For Circular knitting machine:
Diameter of the Machine X Gauge of the Machine X 3.14
For example: Diameter of the machine is 18” and Gauge of the machine is 24. Then thenumber of Needles on the machine would be-
18 X 24 X 3.14 = 1356
For Flat Bed knitting machine:
Length of the Machine needle bed X Gauge of the Machine
For example: Length of the machine needle bed is 56” and Gauge of the machine is 14. Thenthe number of Needles on the machine would be-
56 X 14 = 1568
Faults of Knitting:
1. Hole MarkCauses:
Holes are the results of yarn breakage or yarn cracks. During loop formation the yarn breaks in the rejoin of the needle hook. If the yarn count is not correct on regarding structure, gauge, course and
density. Badly knot or splicing. Yarn feeder badly set.
Remedies:
Yarn strength must be sufficient to withstand the stretch as well asuniform.
Use proper count of yarn. Correctly set of yarn feeder. Knot should be given properly.
2. Needle MarkCauses:
When a needle breaks down then needle mark comes along the fabrics. If a needle or needle hook is slightly bends then needle mark comes on the
fabrics.
Remedies:
Needle should be straight as well as from broken latch.
3. Sinker MarkCauses:
When sinker corrode due to abrasion then some times can not hold a newloop as a result sinker mark comes.
If sinker head bend then sinker mark comes.Remedies:
Sinker should be changed.
4. StarCauses:
Yarn tension variation during production. Buckling of the needle latch. Low G.S.M fabric production.
Remedies:
Maintain same Yarn tension during production. Use good conditioned needles.
5. Drop StitchesCauses:
Defective needle. If yarn is not properly fed during loop formation i.e. not properly laid on to
the needle hook. Take-down mechanism too loose. Insufficient yarn tension. Badly set yarn feeder.
Remedies:
Needle should be straight & well. Proper feeding of yarn during loop formation. Correct take up of the fabric & correct fabric tension. Yarn tension should be properly.
6. Oil stainCauses:
When oil lick through the needle trick then it pass on the fabrics and makea line.
Remedies:
Ensure that oil does not pass on the fabrics. Well maintenance as well as proper oiling.
7. Rust stain
Causes:
If any rust on the machine parts.Remedies:
If any rust on the machine parts then clean it. Proper maintenance as well as proper oiling.
8. Pin holeCauses:
Due to break down or bend of the latch, pin hole may come in the fabric.Remedies:
Change the needle
9. Grease stainCauses:
Improper greasing Excess greasing
Remedies:
Proper greasing as well as proper maintenance
10. Cloth fall- outCauses:
Cloth fall- out can occur after a drop stitch especially when an emptyneedle with an empty needle with closed latch runs into the yarn feederand remove the yarn out of the hook of the following needles.
Remedies:
Make sure all the latches of needle are closed with feeding yarn after adrop stitch.
11. Barre:
A fault in weft knitted fabric appearing as light or dark course wise (width wise)Stripe.
Causes:
This fault comes from yarn fault. If different micro near value of fiber content in yarn. Different lusture, dye affinity of fiber content in yarn. During spinning different similar classes of fiber is mixed specially in
carded yarn & these fibers have similar characteristics.
In draw fame different similar classes sliver is mixed and make one sliver.Remedies:
We can use this fabric in white color.
12. Fly dust:Causes:
In knitting section too much lint is flying to and fro that are created fromyarn due to low twist as well as yarn friction. This lint may adhere orattaches to the fabric surface tightly during knit fabric production.
Remedies:
Blowing air for cleaning and different parts after a certain period of time. By cleaning the floor continuously. By using ducting system for cleaning too much lint in the floor. Over all ensure that lint does not attach to the fabric.
13. Yarn contamination
Causes:
If yarn contains foreign fiber then it remains in the fabric even afterfinishing,
If lot, count mixing occurs.Remedies:
By avoiding lot, count mixing. Fault less spinning.
13. Yarn Faults: Neps. Slubs. Yarn count variations. Thick/Thin place in yarn. Hairiness
Flat Knitting Machines Fault:
1. Holes:

When buyer gives the final approval the fabric is sent to production floor for the bulkproduction.
Properties test
Color fastness to rubbing (wet & dry):
Procedure:
Firstly a sample of size (14 × 5) cm is taken at Wales & Course wise. The crocking cloth is
put on to the finger &is staged by finger clip & run 10 times in 10 seconds manually &
assesses the crocking cloth with gray scale.
The crocking cloth is placed on the water, it will suck some water and crocking cloth is then
squeezed. Then place the wet rubbing cloth on to the finger and stag with finger clip and run
10 times in 10 seconds manually. The crocking is then assessed cloth by gray scale for wet
rubbing. Wet and dry rubbing are checked according to buyer’s requirement.
Color fastness to washing. (ISO/05-CO6):
Procedure:
1. Size of specimen: Sample &multifibre at (10 × 2) cm then stitch.
2. Detergent: 4g/l ECE detergent (WOB) + 1g/l sodium per borate put in distilled water
& cooled at 20°C & measured PH (where necessary).

Pilling test:
Procedure:
The fabric 12.5 x 12.5cm is cut & balanced mark should be 10cm by using template. Thenthe fabric is sewn so that it can be firmly fit in the tube a moulded polyurethane tubes.Thenfour tubes are placed in a box & started 60±2 rev/min for 5 hrs or according to buyerrequirement. Then the fabric is assessed by putting tested specimen on the cabinet &compared with standard photographs.
Shrinkage &Spirality test:
Buyer’s requirements:
Template size: 50cm & 35cm, 25.5cm &18cm (use after quick wash).
Shrinkage: length wise--- 5%

Dyestuff Strength test:
Dyestuff strength test is very important for any textile dyeing industry.
A dye comes to industry then a sample fabric is dyed first to make it a reference. When thatdye is used and finished from inventory, new dye is ordered. But it is not sure the dye thatreached newly, will make a fabric as much dyed as before. That is why after arriving of dyeto the factory it is used to make a sample. Then this newly made sample is checked in respectof previously dyed sample. If the two samples match with each other, it is resulted that thestrength is okay. But if not match then the amount to be given (less or more) is determined.
Thus the strength of dyestuff is measured in this way.
Remarks:
The laboratory of the factory is well enough to make quality products. But more attention tolaboratory is required to make it more efficient. The information’s that lacks about laboratoryin this report is just the result of the unavailability of time of the depart
Chapter Eight:
Dyeing section
Cellulose:
When all impurities have been removed from the natural cotton fiber, cellulose remains.Cellulose has an empirical formula of (C6H10O5) n. pure cellulose is a white substance with a specificgravity of 1.5. It burns freely in air with a luminous smokeless flame. Cellulose is insoluble in waterand alkalis but dissolves in cold concentrated sulfuric acid. Like other carbohydrates, when heatedwith concentrated sulfuric acid it swells up, forming a mass of carbon. It is also attack by hydrochloricacid nitric acids.
When hydrolyzed with dilute acids an almost theoretical yield of glucose is obtained. This indicatesthat cellulose is a long-chain polymer produced by linking together a large number of glucose units.Starch and glycogen are also polymers of glucose but they have no fiber forming attributes.
From the foregoing it will be apparent that cellulose is a polymer of glucose, and it must contain alarge number of – CH2OH and CHOH groups.
The repeating unit in the cotton polymer is cellobiose, which consists of two glucose units. Cellobioseis hydrolyzed by the enzyme emulsion, which it is known, will only break down links between betaglucose molecules. cellobiose consists of two beta glucose molecules linked together at the 1:4 carbonatoms.
The most important chemical grouping on the cotton polymer is the hydroxyl groups or -OH groups.These are also present as methylol groups or – CH2OH. Their polarity gives rise to hydrogen bondsbetween the – OH groups of adjacent cotton polymers. Van der Waal’s forces also occur butcompared with the hydrogen bonds, the Vander Waal’s forces are of little significance.
Chemical composition of raw cotton:
Component Main location Relative amount
Cellulose Secondary wall 86.8 %
Oil and Wax Cuticle 0.70 %
Pectins Primary cell wall 1.0 %
Carbohydrates Primary cell wall 0.50 %
Protein Lumen 1.2 %
Salts Lumen 1.0 %
Water Whole 6.8 %
Others 2.0 %
Classes of dyes on the basis of suitability of dyeing different fibers:
Sl. no Name of dyes Suitable for Fibers
01 Acid dyes Wool, silk and Nylon
02 Basic dyes Nylon, Acrylic, Acetate Rayon, Silk, Wool and Jute
03 Direct dyes Cotton, Viscose Rayon, Linen, Nylon, Wool and Silk
04 Azoic dyes Cotton, Viscose and Linen.
05 Vat dyes Cotton, Viscose and Linen.
06 Sulpher dyers Cotton, Viscose and Linen.
07 Reactive dyes Cotton, Viscose, Linen, Wool, Silk and Nylon.
08 Disperse dyes Polyester, Nylon, Acrylic, Acetate Rayon and Triacetate Rayon.
Theory of Reactive Dyeing:
Reactive dyes are colored compounds and the only class of dyes that form covalentbonds between the dye molecules and the fibers. The dye contain reactive group which reactwith the fiber and make covalent bond with the fibers in the alkaline condition and act as anintegral part of the fiber is called reactive dye. Reactive dyes may be used for coloration of
cellulose and protein fibers and this is the most important class of dyes for dyeing andprinting of cellulosic fiber.
Structural characteristics of Reactive Dye:
Characteristics structural features of reactive dyes are as follows ---
D –B – R - X
Where,
D = Dye part
B = Bridging group
R = Reactive group bearing part
X = Reactive group.
Dyeing mechanism is completed by three stages-
Exhaustion of dye in the presence of electrolyte
Fixation of dye under alkaline condition
Wash of the unfixed dye from material surface
Exhaustion:when the fabric is immersed in the dye liquor an electrolyte is added toassist the exhaustion of dye. Here NaCl is used to neutralize the negative chargeformed on fabric surface & puts extra energy to penetrate dye molecules.
Fixation: fixation of dye means the reaction of reactive group of dye with theterminal -OH group of fiber& thus forming strong covalent bond with fiber.Controlled by maintaining ph by adding alkali properly.
Wash off:as the dyeing is completed a good wash must be applied to remove extraor unfixed dye from surface of fabric & for level dyeing it is important.
Reaction with Cellulose Fiber
Reactive dyes formed covalent bond with cellulosic fiber by Nuclueophilicsubstitution and addition reaction. The reactions are as follows ----
Substitution reaction:
D – R – Cl + HO - Cell D – R – O – Cell + HCl
Addition reaction:
D – F – CH2 = CH2 + HO – Cell D – F – CH2 – CH2 – O – Cell
Reaction with water:
The cold brand reactive dyes are highly reactive in nature. They react also with waterand get hydrolyzed. The reaction is as follows ----
D – R – Cl + HOH D – R – OH + HCl
The hydrolyzed dye is also colored substances and has very low substantivity for thecellulosic fiber. So they are attached with fiber surface after dyeing. If they do not washedaway from the fiber surface the fastness property of the fiber must be very low.
Dyes: The molecules of the organic compounds called dyes are responsible for the color of
dyed and printed lest tile fabric materials. Dye molecules are colored became they are
selectively able to absorbed and reflect incident light. Dyes molecules contain at least one of
each of the radicals called chromophores and auxochromes.
Pretreatment:Pretreatment is the preparation period of fabric fro dyeing. For getting proper fastness offabric and proper dyeing pretreatment is a mandatory process.
Demineralization:It is a process of removing mineral materials from the water. It is done in water treatmentplant. Water from natural sources contains many mineral materials which may hamper thedyeing process. If the mineral materials are present in water then it may lead to uneven shadein dyeing. Besides it may also damage the fabric and the machine.
Scorning:The process to remove fats, oil, waxy substances and added the impurities by
certain percentage of alkali treatment and which increase the absorbing power of the textile
units, is called scouring.
Bleaching:The process by which the natural color of a fiber can be removed and make the
textile this pure white and bright is called Bleaching.
Wetting agent:The chemical which is used for quickly moisten or watering the textile
units is called wetting agent.
Detergent:Detergent are nothing but a chemical which is used for clearing the textile units
or to remove fats, oil and wash. It is know as surface active agent.
Labeling agent:The chemical which are used for dyeing just to give level shade or even
dyeing is called leveling agent.
Enzyme: It is one kind of biocatalyst. It is based on problem. It is soluble in water but
insoluble in acid and alkali.
Salt:Act ad erectility, helps to exhaust dye molecules to the fiber.
Exhaust:The absorption of dye moleules from the dye liquor by the fibers being dyed.
Electrolyte:A compound which is aqueous solution or in the mother state, inducts an
electric current and is simultaneously decomposed by it into inns compounds which
dissociate into inns and /or radicals in aqueous solution.
Hydrolysis:The chemical decomposition of a substance by the action of water, the water
itself being also decomposed. Acids and alkalis often catalyses hydrolysis. The destructive
effect of hydrolysis upon fiber polymers will then also result in the rupture of inter- polymer
forces of attraction.
Hydrophilic:Having a strong affinity for water, or moisture absorbent
Hydrophobic:Having an aversion to water, non-absorbent or water repellent.
Components:Upon which dyeing Process Depends:
(1) Sulostrate
(2) PH
(3) Dyeing Assistant
(4) Temperature
Dyeing AssistanceThese are added in dyeing bath for which dyeing affinity is increased
is called dyeing asst.
(1) Electrolyte
(2) Leveling agent
(3) Carriers
(4) Solvents
Factors to be considered for dye & dyeing process selection:
(1) Hue
(2) Shade
(3) Brightness
(4) Cost
Topping:The application of further colorant not necessarily of the same hue/class to a dyed
substance in order to adjust the lather to the denied final color is called topping.

Chapter Nine:
Finishing section
Introduction of Finishing:
Textile finishing involves treating a textile material in such a way that the product has the
desired properties required for its intended useand therefore has great market value. The
desired properties may include the fabric dimensions and their stability, its weight, drape,
appearance, softness and handle, as well as any required functional properties such as
resistance to creasing, flame, water, oil, dirt or bacteria. Textile finishing is therefore an
extremely diverse field involving an extensive range of chemicals.
The degree of permanency of a particular finish for a fabric depends on its intended use. The
chemicals used may weigh the fabric to make it easy to slide and handle, or allow smooth
penetration of a sewing needle to minimize needle breakage.
Anyone involved in textile coloration must be aware of the influence of preparation process
on the dyeing behavior of the fabrics as well as the finishing chemicals on the final color of
the goods and on their color fastness properties. Without this knowledge, nobody can ensure
the ultimate color and its fastness properties.The techniques of finishing depend on the following:
Nature of the fabric,
i.e. chemical composition, state, weave etc. this determines the appearance,
i.e. transparency, luster, fullness, weight, whiteness etc.
After dyeing, knit fabric is required to finish. During dyeing all knit fabric are dyed in tubular
form. According to buyer's requirement knit fabric are finished in Open form or tubular form.

must ensure that the best qualities of raw material (with economical consideration) are used
in
production.
The Yarn should be with a known concentration and high degree of purity.
The yarn & Lycra should be compatible with each other.
The fabric must be with out faults, with proper absorbency, whiteness as
per requirement of the subsequent process.
Process control: The method chosen for process must be provided with necessary
parameters.
During knitting, samples are taken and G.S.M checks with the reference
samples.
If not properly reset the machine parameter.
Sample is collected after fixation & matched.
During finishing, temperature, speed, padder pressure, overfeed should be
controlled as per requirement.
GSM, width, spirality, shrinkage (both length & width) should be
maintaining as per buyer requirement.

Finish fabric inspection:
Purpose:To ensure that only an acceptable quality fabric is used for producing garments and
proper quantity of shipment is received from the supplier.
Scope:All produced and incoming fabrics of Fakir Knitwears Ltd.
Procedure: Store in charge will check the received fabric with the reported length,
color and type of fabric with the stated shipment document quantity and
the actual order quantity.
The finding will be recorded in inventory report and discrepancy regarding
fabric type, color and length will be notified to the Factory
Manager/Manager (Dyeing & Finishing).
For in-house products quality control officer will guide all over inspection.
1. Body & rib inspection:All rolls are kept in front of the inspection m/c time to time as require. The fabric are
spread over the milky white acrylic inspection board ensures high transparency and even
reflection of light. Then by the inspection machine fabrics are inspected visually at a
standard speed against light. For any major or minor faults like thick-thin, barre mark, fall
out, contamination, fly, holes, oil lines, needle line, slubsetc are recorded in inspection
report to classify the fabric based on the four points system.
2. Collar & cuff inspection:Collar & cuff are inspected visually under the light box. For any major or minor fault in
collar/cuff like having wrong ply, hole, needle line, slubs, wrong design, first round
problem etc are properly counted and recorded.

Color Fastness:-The resistance of a material to change in any of its color characteristics, to transfer its
colorant to adjacent material or both as a result of exposure of the material to any
environment that might be encountered during the processing, testing , storage or use of the
material. Color fastness types:– Wash fastness to hot water as per ISO method– Wash fastness to cool water as per ISO method– Rubbing fastness (dry & wet)– Light fastness– Perspiration fastness– Dry cleaning fastness– Chlorinated or sea water fastness
Factors affecting color fastness:– Dye size or molecular structure of a dye– Types of bonding (i.e., ionic , co-valent, H-bond etc.)– Amount of dye present in fibre– Chemical nature of fibre or compatibility of dye with fibre– Presence of other chemicals like binder– The actual condition prevailing during exposure and after treatment
Reasons of color loss:– Due to decomposition of dye molecules– Due to removal of external media– Due to reaction of dye molecules with acid, alkali, or perspiration– Due to friction with other surface
Color fastness and other test result:Different types of fastness standard are given below:

Grey scale for assessing change in shade:
EN ISO 105-A03 / IUF 132 / VESLIC C 1211This Grey Scale is for assessing the degree of change in shade caused to a dyed Textile
fabric / yarn in color fastness tests. For example, the change of shade of wool and cotton
fabrics in the wash fastness, perspiration fastness etc. The scale consists of nine pairs of gray
color chips each representing a visual difference and contrast.
The fastness rating goes step-wise from:Note 5 = no visual change (best rating) to Note 1 = a large visual change (worst rating).
The gray scale has the 9 possible values:
5, 4-5, 4, 3-4, 3, 2-3, 2, 1-2, 1.
It is now quite common to measure the Grey Scale change in color instrumentally. This is
made using a suitable reflectance spectrophotometer according to the test method
procedure, EN ISO 105-A05.

Note:
In the CAD section normally they calculate the fabric consumption for a large size sample.
For this, the amount of required fabrics is more. So fabric wastages are more. If it is possible
to evaluate the fabric consumption for each then some fabrics may be save. And it will be
beneficial for the Company.

Process loss:
Fabric loss is a major contribution to material utilization. Minimizing fabric loss during
spreading can reduce the total production costs for garment manufacturing. This is the key
point which has been highlighted in this report. Today garment industry is facing very tough
scenario because of more competitors and less buyers, buyers have many options but
suppliers have very limited choices, the time has gone when there was quota system and
garment industry didn't need to be very many efficient but today suppliers are fighting for
price and quality; on fewer prices better quality is expected. Orders are given to the suppliers
who offer better quality and less prices. So within such scenario, only the things which can
increase profit and minimize loss of a company is fabric saving. Fabric loss in cutting section
may be for following reason.
Inefficient marker
Variation of fabric diameter
Higher GSM than required
More fabric faults
More dyeing faults.

Cost Analysis
Cost analysis
Costing of the product:Costing system mainly describe how the cost of the final product is fixed by the company /
top managements. As it is a garments manufacturing factory, so according to the buyer /
customer requirements of final garments, merchandiser give the consumption of fabric with
specifications. Then it is calculated how much dyestuffs & chemicals are required for
processing. After that, the final cost is fixed including some profit. Then the unit price is
offered to the buyer for their approval.
Costing of a product includes: Yarn cost
Knitting cost
Dyes & chemicals cost
Cost of dyeing
Cost of finishing
Cost of cutting ,sewing, accessories etc
Cost of printing (If any)
Labor cost (direct & indirect)
Factory cost
Office & administrative cost
Sales and caring cost

Water Treatment Plant (WPT):Water for a textile plant may come from various sources. But this water can not be used
directly in textile processing because it contains various salts. These salts are mainly the
carbonates (CO32-), Hydrogen carbonates or bi-carbonates (HCO3
-), Sulphates (SO42-) and
Chlorides (Cl-) of Calcium (Ca2+), and Magnesium (Mg2+). These are called hardness in the
water. These must be removed though water treatment plant.
Water is supplied in different sections continuously by using submersible and centrifugal
pumps.
Methods of expressing the water hardness:
1. In Degrees, and
2. PPM (parts per million)
Hardness measurement calculation:Required EDTA * 1000 * EDTA factorTotal amount of waterPPM =
There are different types of water softening process:1. Soda lime process.
3. Base Exchange process.
4. Demineralization.
5. Soda alum process.
6. Aeration process.
7. Chelation on sequestration.
In Fakir Knitwears Ltd. follow the base Exchange water softening process for softening the
hard water.
Base Exchange process:
This methods depends upon the use of zeolite or Base Exchange complexes. The zeolites are
hydrated silicates of sodium & aluminum with a general formula.

Conclusion
ConclusionThere is large difference between the theoretical knowledge and practical experiences.This is truer in case of the study of Textile Technology. Industrial attachment or,Industrial training is an essential part for textile education because it minimizes the gapbetween theoretical and practical knowledge. The Industrial training increase ourthough a lot about textile technology. It also helps us to know a lot about industrialproduction process, machineries, and industrial management and made us suitable for
industrial life. Besides it gives us the first opportunity to work in industry. So we can sayindustrial attachment prepare us for the expected destiny of practical life.We have completed my industrial attachment fromFakir Knitwears Ltd.During my twomonths long industrial training at Fakir Knitwears Ltd. We got the impression that thisfactory is one of the modern export oriented composite knit garments industry of ourcountry. This factory does not compromise in case of quality. So, they have establishedon-line and off-line quality control of each product. Besides, they also use the goodquality yarn, dyes and chemicals in their production process. Due to this, it has earned a“very good reputation” in foreign market for its quality product over many other exportoriented textile mills. It has very well educated and technically experienced manpowerto get rid of any defect in production process. It has also a good organizationalhierarchy.
My Achievements: We have got a lot of knowledge about the laboratory work and the stepsthat should be maintained before bulk production. We have identified the process sequence dyeing and gathered adequateknowledge about each process sequence. We have earned some mechanical knowledge about dyeing machine. We have found some special points that should be considered duringdyeing production. We have understood about industrial environment and administration.
Some suggestion: Industrial salt should not be used because it corrodes the inner parts ofdyeing machine. Dyeing production needs to increase as well as technical persons need tobe employed there?
More skilled labor should be used in a project and the overall efficiencywill have to be increased. Dyeing machine must keep dust free. There need proper handling of the machine. Check all production parameter regularly. Dyeing floor should keep always net and clean. It kept wet after unloadingthe fabric from the dyeing machine specially, for Athena. Water must beswept time to time. During the transport of the fabric and during the loading of the m/c,fabrics get soiled due to their drawing over the floor. This makes thefabric/part of the fabric dirty. It may require more scouring/bleachingagent or may create stain. Due to the pressure of higher production sometimes machine operatorsdo not maintain accurate time according to the actual process so that lessquality product is produced and may reject. So need to be increasedmachine and reduce the pressure on the operator. Should increase understanding between the top level personal and floorlevel personal. Finishing section need to be enlarged well as more technical persons needto be employed there? The m/c stoppage time should be analyzed and minimized. Themaintenance should be carried out when the m/c is out of action(Wherever possible) and routine maintenance should be carried outregularly.
In the Laboratory there is no technical person, a textile engineer may beemployed here. There is shortage of proper light in the dyeing and finishing floor,specially, when smoke is produced from dryer and stenter. Properlighting should be provided in the floor. The person at the top level of a department must take good care of thetrainees & he should provide all kinds of support to them.
Limitations of the report: Because of secrecy act, the data on costing and marketing activities havenot been supplied. We had a very limited time. In spite of our willing to study more it was notpossible to do so. Some information in different sections are not included as these were notavailable. It is not possible to hold the whole thing of a textile industry in such asmall frame as this report. So, try our hard to summarize all theinformation that we are provided.
