Abstract:
Thermoplastic polyether polyurethane polymers are disclosed which are mixed with a crosslinking agent to achieve long run times in a melt spinning process to make elastic fibers. The crosslinking agent is preferably a polyether or polyester polyol reacted with a diisocyanate. A melt spinning process is also disclosed using a polyether polyurethane with a crosslinking agent. Long melt spinning run times can be achieved without experiencing excessive pressure buildup in the spinneret and fiber breakage. The thermoplastic polyether polyurethane polymers are made by reacting: (1) a blend of two or more hydroxyl terminated intermediates wherein one intermediate is a polyether intermediate and has a higher number average molecular weight than the other said polyether intermediates, and wherein the weighted average number average molecular weight of said blend is greater than 1200 Daltons; (2) at least one polyisocyanate; and (3) at least one hydroxyl terminated chain extender. Melt spun fibers disclosed have excellent dye pickup, bleach resistance, and color fastness. The melt spun fibers can be dyed with polyester fibers and retain excellent physical properties.

Abstract:
A method for manufacturing dyed woven or knitted fabric includes preparing woven or knitted fabric using metallic yarn and normal-pressure dyeing polyester yarn having an elasticity modulus of 400 to 600 kg/mm2 and an elongation of 30 to 40%, fabricating a dye bath by putting a dye solution obtained by dispersing a dye in water, dyeing the woven or knitted fabric by putting the prepared woven or knitted fabric into the fabricated dye bath, raising a temperature of the dye bath starting from 35 to 45° C. for 30 to 50 minutes at a rate of 1.2 to 1.5° C./min, and maintaining the heated dye bath at 90 to 100° C. for 15 to 25 minutes, and washing the dyed woven or knitted fabric. The dyed woven or knitted fabric has a light reflection reduction rate of 20% to 30%.

Abstract:
A process for making multi-colored fabrics from a single dye formula is described. The process involves providing a substrate including synthetic fibers, with the substrate having defined regions where the synthetic fibers have differing levels of fiber orientation, and dyeing the substrate with a dye bath containing at least one dye from at least two of the categories of a) high contrast dyes, 2) medium contrast dyes and c) low contrast dyes, to thereby produce a multi-colored substrate from a single dye formula. The substrates are characterized by having a base of a first color and patterned regions of a different color, with the regions of different colors corresponding to regions of different levels of fiber orientation.
