FIBERS OF CRUST - LINEN

Apstract

In the seminar work is a brief description of the coral linen fibers, the way of obtaining

flax fiber and its technical characteristics.

Initially described are general terms for Leno, given ways to obtain technical fibers or

getting tow and skein. Given the structure, thickness and length properties, chemical

composition of cellulose, pectin, protein and wax. Finally given the use od the linen

fibers.

Key words:skein, tow, cellulose, pectin, protein and wax.
