Textiles Notes 2/8 – 2/10 2/8 Manufactured Fibers (synthetic) 1910 – Rayon 1939 – Nylon 1959 – Spandex 1980 – Microfibers 2002 – PLA Now – Nanotechnology Rayon First ever manufactured fiber in U.S. Primarily cellulose in content Greatly resembles cotton in its chemical properties Flammable Polyester #1 produced manufactured fiber in U.S. Medium weight, very good strength and abrasion resistance Almost completely hydrophobic CoolMax fabric example of sports ware made of polyester because of wicking properties Nylon #2 produced manufactured fiber in U.S. Light weight, excellent strength and abrasion resistance Good elasticity and resilience Acetate From cellulose acetate substance Excellent drape and luxurious hand Fair strength, pilling and static Acrylic Manufactured fiber used as wool substitute Lightweight fiber, good sunlight resistance, good drape, resiliency and elasticity fair strength, pilling and static 2/10 Olefin Polypropylene and polyethylene types Lightweight, good strength, abrasion resistance Almost completely hydrophobic End use: running, cycling, diving, surfing apparel Spandex First commercially available in 1959 by DePont Elastomeric manufactured fiber (stretch up to 500% and back) Filament/Monofilament Called ‘elastane’ in Europe Yarns Spun Yarns Fuzzy surface Composed of relatively short fibers twisted or spun so they hold together Less yarn uniformity, smoothness, luster, strength than filament yarns End uses include tshirts, sweaters, blankets, etc. Ex. Cotton, acetate, wool, polyester, rayon, nylon Filament yarns Smooth surface Composed of continuous strands of fibers that may be miles long Usually twist is not high Special effects require high twist for filament yarns More yarn uniformity, smoothness, luster, strength than spun yarns End uses include linings/outer shells of active jackets Multifilament (flexible) and Monofilament (stiff) Ex. Silk, acrylic, polyester, spandex, rayon, nylon, acetate Staple Fibers Made into yarn by a mechanical process that first makes the fibers parallel, then alternately pull and twist them Twist is critical Microfilament Improved characteristics o Softer hand, better drape, better wicking effect, more vivid color contrast
