Chapter 6 Exam Notes
Textile Exam Notes Chapters 6,7 and 8
* Generic Names – Similar chemical composition * Cross-dye able fibers – NOT colored * Trade Names- Company Name * Three General Steps of spinning process:
P-Prepare4 dope/melt
E- Extrude
S- Solidify * Fiber Size largest to smallest:
Macrofiber
Microfiber
Ultrafine
Nanofiber
* Microfiber-Strength
* Ultrafine
Microfiber – Technical Application
Nanofiber
* Dope- raw materials dissolved * Melt- polymer generated * Wet spinning: -Dissolved by chemicals -Spun into chemical bath -Solidifies * Example generic name: DACRON * Tencity- Increase Stretching or drawing * Antisitatic -Additives to polymer or spinning Solution process
Delustering – Additives to polymer or spinning Solution process
Change in cross sectional shape -Spinneret Modification
Fiber size and shape- Spinneret Modification
* Bicomponet- COMPLEX modification * Low pilling- Molecular structure * Self-crimping- Modification of fiber spinning
* Azlon- regenerated protein fiber
* Fiber spinning is the process used whereby a chemical solution isd converted into filament fiber.
* Lyocell is NOT a type acetate
* Rayon is significantly heavier than cotton.
* Solution dyed Fibers are NOT modified for to accept dye more readily.
* Parent Fibers are NOT fiber that a have been modified for specific end uses.
* Cross-Dyeable fibers are NOT colored when they are extruded.
* Acetate is often used in lining fabrics because of its smooth, slick surface and ease of handling in sewing facilities.
* Acetate has poor abrasion and heat sensitive.
* Antistatic compounds increase the electrical conductivity of fibers
* Dry Spinning is the spinning method used to produce acetate.
Lyocell
-cotton-like
-fibrillate with abrasion
Nylon * Picks up color from soil and wash water * Excellent
