摘要:
The present invention is directed to a reactive dye-dyeable polyurethane-urea elastic yarn including a reaction product of at least two polyols, a diisocyanate compound, a diamine chain extender, an amine chain terminator, and a diethylenetriamine compound, wherein one of the polyols is polyethylene glycol, which is included in an amount of 20 to 30.0 mol % based on the total amount of the polyols, a polyurethane-urea polymer includes 10 meq/kg to 45 meq/kg of primary amine ends, and the capping ratio (CR) of the diisocyanate to the polyols is 1.8 to 2.0.
摘要:
The present invention relates to a process for providing a bleached look in the color density of the surface of dyed fabric, especially cellulosic fabric such as denim, comprising use of a phenol oxidizing enzyme such as a peroxidase or a laccase, a hydrogen peroxide source and an enhancing agent represented by formula (I). ##STR1##
摘要:
A dyed union knit fabric comprised of at least a polyurethane elastic fiber containing a chlorine-induced degradation inhibitor in a proportion of 0.5-4.5 weight % relative to the weight of the fiber, and a polyamide fiber and/or a cation dyeable polyester fiber, which has been dyed with mixed dyes of acid dyes, dispersion dyes, metal-complex dyes, reactive dyes and direct dyes, and markedly improved in resistance to chlorine-induced change in shade by allowing to contain at least one compound having a reaction amount of chlorine of 50 milliequivalent per gram or more, specifically one member of mono- and/or polyhydroxybenzene derivatives in a proportion of 0.1-20 % relative to the weight of the fiber; and a method for manufacturing same. According to the present invention, excellent resistance to chlorine-induced change in shade as well as chlorine-induced degradation can be afforded to the dyed union knit fabric.
