2. End Uses of Rayon:
Apparel - dresses, jackets, slacks, sport shirts, sportswear, suits, ties
Home Furnishings - Bedspreads, blankets, curtains, sheets, tablecloths
Industrial Uses - Industrial products, medical surgical products, nonwoven
products, tire cord
Rayon is a versatile fiber
• Rayon is very soft, cool comfortable and very good absorbent property but
could not be able to protect body heat and used in humid steamy climatic
conditions.
• Rayon fibre has the same comfort property as natural fibres.
• Rayon can replicate the feel and texture of silk, cotton linen and wool.
• Rayon can easily be dyed in variety of colors
• Rayon has very lower elastic recovery of any fibre.
• HWM rayon is very stronger and reveals good durability. HWM rayon can be
machine washed.
• Usual rayon fibres recommended care for dry cleaning purpose only.
Rayon is a major feedstock in the manufacture of carbon fibre. Grasim of India
is the major producer of rayon in the world which is claiming 24% market share.
3. End Uses of Acetate:
Apparel - dresses, wedding and party attire, home furnishings,
draperies, upholstery
Industrial Uses - Cigarette filters
Fiber properties
Acetate is a very valuable manufactured fiber that is low in cost and has
good draping qualities. Acetate is used in fabrics such as satins, brocades,
and taffetas to accentuate luster, body, drape and beauty.
Hand: soft, smooth, dry, crisp, resilient
Comfort: breathes, wicks, dries quickly, no static cling
Drape: linings move with the body linings conform to the garment
Color: deep brilliant shades with atmospheric dyeing meet colorfastness
requirements
Luster: light reflection creates a signature appearance
Performance: colorfast to perspiration staining, colorfast to dry cleaning,
air and vapor permeable
Tenacity: weak fiber with breaking tenacity of 1.2 to 1.4 g/d; rapidly loses
strength when wet; must be dry cleaned
Abrasion: poor resistance
4. End Uses of Aramid:
Flame-resistant clothing, protective vests and helmets, tire and mechanical
rubber goods reinforcement, ropes and cables, sail cloth, sporting goods.
Aramids share a high degree of orientation with other fibers such as ultra
high molecular weight polyethylene, a characteristic that dominates their
properties.
Properties
good resistance to abrasion
good resistance to organic solvents
nonconductive
no melting point, degradation starts from 500°C
low flammability
good fabric integrity at elevated temperatures
5. End uses POLYESTER
Apparel: Every form of clothing
Home Furnishings: Carpets, curtains, draperies, sheets and pillow cases, wall
coverings, and upholstery
