Document Summary
Three main regenerated fibers: (primarily cellulosic) rayon, acetate/ triacetate, lyocell. Chapter 8: synthetic fibers (melt spin fibers, thermoplastic fibers, petro) Raw material is made (synthesized from other shorter molecules) then that raw material is made into fibers (or other things) Raw material is produced through addition or condensation polymerization -cold or hot drawn often modified/engineered. Solubility only reliable test - most are melt spun (acrylic isn"t and has significantly different properties: 1939- first syn. fiber (research started in 1928) melt spun polyamide, condensation polymer cold drawn, most elastic of reg. syn. Made from polymers that do not exist in nature. Nylon and polyester have more in common than nylon and anything else. Electro static, abrasion resistance and strength, resilience is good to excellent (except acrylic) Pilling can be a problem and non biodegradable. Polyester: 1951 (usa dacron by dupont) melt spun, condensation polymer hot drawn, work horse of apparel industry - like most syn.
