Document Summary

Polymerization: process of joining many small molecules (monomers) to form one large compound. Degree of polymerization: the number of monomers connected to form polymer. Amorphous: polymer chains arranged in a random disorganized way, not parallel. Crystalline: polymer chains are parallel and affect the strength of fiber. Tenacity: ability to withstand a heaving pulling force. Ability to return to original shape after bending, twisting, or crushing. Regain: measure of moisture content of fiber in. The ability to retain given size and shape through use and care. Shrinkage resistance: ability of fabric to retain given size through care or cleaning. Elasticity or elastic recovery: ability of extended fiber, yarn, or fabric to return immediately to its original length. Fab: bend caused by distortion of yarns due to weave/crimp. Fib: waves/twists along fiber filament: long continuous fiber greige goods: chains parallel to each other and to the fiber"s longitudinal axis stretching or drawing: increase fiber orientation and equilibrium with standard testing atmosphere.
