Man-Made Fiber

Part 1: Man-made Fiber

1.Fiber Name: Rayon
Spinning Method: Wet spun
Trade Name(s): Viscose Rayon, Bemberg Rayon, Micromodal Rayon
Major Advantages: Highly absorbable, easy to dye, cool hand, soft drape, can be made to resemble fibers
Major Disadvantages: Much weaker when wet, poor resiliency, low appearance retention, very low elasticity
Common End Use(s): Woven fabrics, apparel, draperies, upholstery, technical wipes, medical supplies
Major Modifications and/or associated Trade name(s):
- Optically brightened
- Lenzing FR (flame retardant)
- High Absorbancy
- Hollow cupromonium Rayon (Bemberg) (Copper)
- HWM Rayon (High Wet Modulus)
- High Tenacity Rayon (used in tire cord)
- Micro Modal Rayon (cross sections and sizes)

2.Fiber Name: Lyocell
Spinning Method: Wet spun
Trade Name(s):
Major Advantages: Strongest of all manufactured cellulose fibers, comfortable hand, nice fluid drape, can resemble many different fibers, conducts heat/electricity well
Major Disadvantages: Weaker when wet, can shrink, subject to mildew damage, flammable, dryclean only, poor abrasion resistance - fibrillates
Common End Use(s): Professional buisiness wear, leotards, hosiery, casual weat, upholstrey, window-treatment fabrics
Major Modifications and/or associated Trade name(s):
-Tencell 100A

3.Fiber Name: Acetate
Spinning Method: Dry spun
Trade Name(s): Celanese Acetate, Celstar Acetate, Chromspun Acetate, Estron Acetate, MicroSafe Acetate
Major Advantages: Good body, good drape, resistant to mildew
Major Disadvantages: Poor thermal retention, weak when wet, low absorbancy, poor conductor of electricty, poor resiliency, can shrink, poor sunlight resistance, flame retardent
Common End Use(s): Clothing, cigarrette filter
Major Modifications and/or associated Trade name(s):
-Different cross section & fiber sizes
