Document Summary

Provide characteristics needed for serviceability: need to be readily available. Textile fibers and their properties: natural fibers: fibers grown or developed in nature in recognizable forms. All natural fibers are staple fibers, except for silk. Examples: cotton, silk, bamboo, linen, wool, hemp, leather (not really fabricated/not a fiber: manufactured or man-made fibers: made from chemical compounds produced in manufacturing facilities, original form not recognizable as a fiber. All manufactured fibers produced in filament form, but many are cut into short, staple lengths for further processing.

Denier: weight, in grams, per 9000m; manufactured fibers and yarns, smaller the number, finer the fiber. Tex: weight in grams of 1000m of fiber and yarns, smaller number finer fiber.
