Document Summary

How it"s made: prepare a viscous dope (a thickening solution) extrude dope through spinneret (no more than 350 fibers per spinneret) solidify fiber. Fiber is spun through spinneret in a chemical bath. Dry: fiber solidifies by evaporation once extruded through spinneret. Types: only need to know mineral is from solid or crystal structure and azlon is protein made from soy or corn. Fiber modifications: size & shape//molecular structure//additive// modification of procedure. Regenerated fibers: modified cellulosic fiber & protein fibers//only been around for 80 years. First regenerated cellulose fiber made from wood pulp. Can now be made to imitate cotton and linen. Similar to cotton: absorbency//soft//good dyeability// biodegradable// similar burn identification and chemical solubility. Differences to cotton: high dry strength than wet strength//luster, length and diameter can be controlled. Lyocell introduced in 90s us and europe started as type of rayon wet spun. Actate first thermoplastic fiber// 2nd manufactured fiber in us. Fair water absorbency- static build up and resists mildew.
