Different Fabric Structures

Woven Knit Non-woven

Woven Fabric Structures Plain Weave

Basic Weave Pattern Yarns are square Modified Version

Rip Stop Based On Plain Weave w/ Extra Yarns in the Rips 2 or 3 ends Increases trap tear strength, does not increase tensile strength

Twill Weave Series of diagonal lines, or twill lines Good Flexibility

International Firefighting Protective Clothing Standards

AS/NZS 4967:2009 - Protective clothing for firefighters - Requirements and test methods for protective clothing used for structural firefighting

NFPA 1971 – 2013 Edition – Standard on protective ensembles for structural firefighting and proximity firefighting.

EN 469:2005 – Protective clothing for firefighters – Performance requirements for protective clothing for firefighting.

ISO 11613-1999 – Protective clothing for firefighting – Laboratory test methods and performance requirements.

What is the Function of the Outershell?

Provides tough, durable first line of defense against heat, flame and abrasion

Protects the moisture barrier and thermal barrier

Offers resistance to rips, cuts, and tears

Allows garment to shed water

Typically made from woven fabrics

Trapezoid Tear Strength ASTM 5587 Fabric begins with a small cut

Large clamps are placed along two lines in the shape of a trapezoid

As the fabric is torn, the machine measures the average of five “displacements” or tears

Results are pounds of force or Newtons
