Document Summary
Fibers grown or developed in nature in recognizable forms. Fibers are made from chemical compounds produced in manufacturing facilities. Original form not recognizable as a fiber. Physical structure: evaluated with nakes eye or microscope. Length of fiber: staple fibers short. Filament: long continuous fiber, yards and meters. Filament two: filament crimped then cut. Process of joinging many small molecules (monomers to form one large compound. Amorphous: polymer chains not parallel, fibers are weak, flexible, absorbent, low elastic, but good elongation properties. Oriented: polymer chains parallel to each other & to longitudinal axis, stiff, nonabsorbent, low elongation, good elasticity. Stretching or drawing: increase orientation & crystallinity. Cover: ability of a fiber to conceal or protect. Drape: ability of a fiber to allow light to pass through, sheen caused by light reflected from a fiber"s surface, the manner n which a fabrics hangs over a form. Texture: nature of a textile surface, tactile quality.
