Abstract: The use of 4,4'-azobis(4-cyanovaleric acid) and its salts as water-soluble free radical initiators, and simultaneously or alternatively the addition of catalytic amounts of tetrakis(hydroxymethyl)phosphonium sulfate as a polymerization accelerator, in the sequential polymerization and acid-catalyzed grafting of N-methylolacrylamide on cotton textiles from a single treating bath in a padding and two-stage heat curing operation, is disclosed. The cotton textiles as treated are free from discoloration and excessive tendering produced by peroxide-type initiators, and these textiles exhibit increased smooth drying performance, abrasion resistance and strength relative to textiles treated conventionally with dimethyloldihydroxyethyleneurea to comparable wrinkle recovery angles.

Abstract: The present invention relates to a textile treatment process which comprises applying to a textile substrate of natural or synthetic polyamide either before or after dyeing, a compound of formula I, ##STR1## in which R is an C.sub.6-20 alkyl radical, each ofR.sub.1 and R.sub.2, independently, is --CH.sub.2 --CHOHCH.sub.2 --X or C.sub.1-4 alkyl, with the proviso that the total number of carbon atoms in R+R.sub.1 +R.sub.2 is from 8 to 26;X is chlorine or bromine,Y is a non-chromophoric anion, andn is a whole number from 1 to 3,which treatment before dyeing increases the affinity of the substrate for anionic dyestuffs and after dyeing improves the wet-fastness of the dyed substrate.
Abstract: A pharmaceutical tablet consists of a substrate containing a medicament and may be covered with a coating, said coating including a pigment comprising a natural water insoluble edible powder dyed with an edible natural dye. The pigment for coloring the tablet, or other pharmaceutical products, as well as food and cosmetics, is made by suspending a natural water insoluble edible powdered substrate in an aqueous vehicle and dyeing the suspended powdered substrate with an edible natural dye. The liquid is removed to obtain the dry pigment powder of the invention which then can be suspended in a suspending medium and used for coating products to be colored such as food, drug and cosmetic products.

Abstract: A process for producing a regenerated cellulose fiber having a good hand and a good shrink resistance characterized by attaching a liquid not readily soluble in liquid ammonia and adsorbable on regenerated cellulose fiber to the surface of regenerated cellulose fiber or attaching a polymer to the surface of regenerated cellulose fiber in the form of a film or not carrying out the surface treatment mentioned above, and adjusting the moisture content of said regenerated cellulose fiber to 5% or more based on the absolute dry weight of said fiber, and thereafter impregnating said regenerated cellulose fiber with liquid ammonia, and subsequently removing the ammonia from the regenerated cellulose fiber.
Abstract: Fibers which are equipped with at least one bleaching agent are obtained in that the fibers are contacted with a dispersion or a solution containing at least one bleaching agent, said dispersion or said solution is allowed to interact to the fibers and then the so treated fibers are dried.Preferably the fibers equipped according to the process of the invention are used as screen gauzes.
