HUEC 2040 Chapter : CHAPTER 6 THE FIBER MANUFACTURING PROCESS
Document Summary
Manufactured fiber: any fiber derived by a process of manufacture from a substance that at any point in the process is not a fiber: difference of fibers is chemistry of the polymer. Generic name: family of manufactured fibers with a similar chemical composition: based on fiber chemistry, approved by ftc-nylon. Trade name: company name used to promote a fiber: engineering for specific end uses, certification requirements, owner sets performance standards for products, tencel-lyocell. Regenerated: from natural material: timber, wood pulp. Convert to liquid form: additives to spinning dope. Prepare viscous dope or melt from chemical compounds. Extrude dope or melt through spinneret to form fiber. Raw material: substance to form solution, cellulose base, crude oil, etc. Spinning solution (dope, melt: material from which fiber is formed. Extrusion: forcing dope or melt through tiny holes in the spinneret. Spinneret: small nozzle through which dope or melt is forced. Filament: spun from spinneret, group to form filament yarns.
