Document Summary
Can have as many as 10,000 glucose monomers per molecule conneted on long linear chains and marraged n a spiral form within the fiber. Can be altered by using chemical treatments or finished. Mercerization: treating yarns or fabrics with sodium hydroxide nauses permentnt physical change. Increases absorbancy and imporaces the dyeability of cotton yarns and fabrics. When treated to be wrinkle resistant: not as stiff and hard as mercerized wrinkle resistant fabrics. Most preferred for many interiors and for warm-weather apparel esp where it is hot and humid. Washed with strong detergents reqires no special care during washing and drying. Soil resistant finished are desirable for some interior and apparel uses. Use of chlorine bleach is good for spot removal excessive bleach weakens cellulose fibers. Less wrinkling occurs in dryer if items are removed immediately. Fabric blends//heat sensitive fiber need to be ironed at low temperature to avoid melting the heat sensitive fiber.
