Document Summary

Fibers are the most basic unit of most fabrics. Fibers have very high aspect ratio: natural fiber: those that are in fiber form as they grow or develop and come from animal, plant, or mineral sources. Plants: manufactured (or man-made) fibers: made into fiber form from chemical compounds produced in manufacturing facilities. Manmade fibers can be made from natural fibers if you chemically process these natural fibers. Manmade fibers can be: petroleum based, cellulose based. Physical aspects: length staple or filament. Staple fibers are short fibers measured in inches or centimeters. Filaments are long, continuous fiber strands of indefinite length, measured in miles or kilometers. Filament tow: produced as a loose rope of several thousand fibers, is crimped or textured, and cut to staple length: diameter thickness of fiber (measured in microns, fineness or linear density. Denier measure of fiber fineness/size, dpf=denier per filament, weight in grams/9000 meters. Denier= (fiber weight (g) x 9000m)/(fiber length)
