Abstract:
A METHOD FOR IMPARTING A DURABLE PRESS FINISH TO CELLULOSIC TEXTILE MATERIALS BY TREATING WITH N-METHYLOLACRYLAMIDE AND ZINC NITRATE AND HEATING TO CURE AND EFFECT CROSS-LINKING THE TEXTILE FINISH FOR PERFORMING THE METHOD AND THE RESULTING CELLULOSIC TEXTILE MATERIAL.
Abstract:
HEATING CRIMPED SYNTHETIC, LINEAR, WHOLLY AROMATIC POLYAMIDE AND POLYIMIDE FIBERS TO A TEMPERATURE IN THE RANGE OF 275*C. TO 400*C. FOR 1 TO 10 MINUTES INCREASES THEIR HYDROLYTIC DURABILITY AND SOLVENT RESISTANCE.
Abstract:
Cellulosic fabric is dyed by affixing a hydroxymethyl phosphonium-nitrogen based polymer to the fabric and thereafter dyeing it with a cotton dye having anionic groups, in an acidic or neutral environment. In addition, a new method of affixing the polymer to the fabric is provided comprising contacting the fabric with a solution of urea and a precondensate of urea and tetrakis hydroxymethyl phosphonium salt.
Abstract:
Capped 1,2-propylene terephthalate-polyoxyethylene terephthalate polyesters useful as soil release agents are disclosed. Preferred polyesters have the formula: ##STR1## wherein each R.sup.1 is a 1,4-phenylene moiety; the R.sup.2 are essentially 1,2-propylene moieties; the R.sup.3 are essentially the polyoxyethylene moiety--(CH.sub.2 CH.sub.2 O).sub.q --CH.sub.2 CH.sub.2 --; each X is ethyl or preferably methyl; each n is from about 12 to about 45; q is from about 12 to about 90; the average value of u is from about 5 to about 20; the average value of v is from about 1 to about 10; the average value of u+v is from about 6 to about 30; the ratio u to v is from about 1 to about 6.
Abstract:
Water-soluble or water-dispersible segmented polyetheresters having a predominantly linear molecular structure and containing(a) 3-45% by weight of terephthalate groups of the formula ##STR1## wherein R denotes hydrogen or methyl,(b) 0.4-6% by weight of terephthalate groups of the formula ##STR2## wherein R.sub.x denotes hydrogen or C.sub.1 -C.sub.4 -alkyl andMe denotes an alkali metal or ammonium ion, and(c) 49-96.6% by weight of terminal polyalkylene glycol groups, all the weights being relative to that of the polyetherester,are used for finishing synthetic fibre textile material.
Abstract:
A process for effecting flame retardation of fibrous structures, such as fabrics, particularly fabrics made from mixtures of natural and synthetic fibers, such as cotton and nylon. The process includes the steps of contacting the fabric to be treated with halomonomers and/or inorganic salts, followed by fluorocarbon grafting, and then by photohalogenation. The aforesaid treatment results in fabrics which are not only flame resistant but also have improved hand, manifested by softness, silkiness, and unwettability of the resulting fabric.
Abstract:
The invention provides compositions intended for the treatment of fibrous materials. These compositions contain at least one cationic polymer, at least one anionic polymer, at least one alkali metal salt and at least one non-ionic surface-active agent or surface-active agent which contains one or more carboxyl or carboxylate groups in addition to non-ionic groups.
