FASH 290 Lecture Notes - Lecture 2: Hydroxy Group, Kenaf, Bamboo Textile
Document Summary
Fash 290 class #3 boardnotes: natural cellulose fibers chapter 4. Natural cellulose fibers: high density, sensitive to mineral acids, absorb moisture, good conductors of heat, heat resistant (don"t melt), you can boil them to sterilize them. Class of insects eat cellulose fibers (glucose), sun resistant, flammable. Convolutions- ribbon like twist that can be turned into a yarn. 19 staple lengths: short staple: , grown in india & eastern asia, uplands: 97% of the us crop. medium staple: 7/8 1 , long staple: 1 3/8 1 (egyptian, pima, sea island) Hydroxyl units- allows cellulose molecule to react with dye and finishes (absorbent), sensitive to damage. Environmental impact is significant many reasons understand these! Bast fibers -from plant stems (longer and stronger than those from a seed) Flax one of the oldest textile fibers (8,000 10,000 bc)- northern ireland, belgium. Hemp - 3-15 feet in length more environmentally sustainable. Kenaf - cordage and other uses similar to jute.
