Abstract: A kind of yarn of animal collagen fiber and the manufacture process thereof, characterized in that the yarn is made of 1-100 WT % of collagen fiber of animal leather, and 0-99 WT % of textile fiber. The yarn of animal collagen fiber is made by the following procedure: choosing raw materials, loosing fiber, assorting, blending, carding, drawing, and twisting, if using the rawhide, the above procedure should add the steps of liming, washing, deliming, tanning and dehydrating. The raw material of the yarn can be the rawhide of any animal, as well as the leftover material or worn-out leather. The yarn has excellent properties, high tensile strength, abrasion resistance, softness, water adsorbent, oil adsorbent, flame-retardant, and can be woven, knitted and braided.
Abstract: An aqueous dispersion for use as a finishing agent for textiles, wherein the dispersion contains a pyrogenically produced, aggregated silicon dioxide powder and a cationic polymer which is soluble in the dispersion, wherein the cationic polymer is present in a quantity such that the particles of the silicon dioxide powder exhibit a positive zeta potential.

Abstract: Compositions are described with organopolysiloxanes which contain crosslinked units and are further crosslinkable. The compositions further contain a polyurethane containing blocked isocyanate groups. They are useful for treating fiber materials, especially textile sheet materials, and can be applied thereto in the form of aqueous solutions or dispersions. Textiles which are 50 to 100% by weight wool and have been finished with the compositions exhibit low shrinkage and low felting tendency during washing operations and also a pleasant, soft hand.

Abstract: Organic fibers are treated with aqueous preparations comprising amino-functional organosilicon compounds of the general formula
H2N—R1—SiR2O(SiR2O)iSiR2—R1—NH2
where
i is an integer from 1 to 1000,
R is an identical or different monovalent hydrocarbon radical having 1 to 18 carbon atoms per radical, and
R1 is a divalent hydrocarbon radical having 2 to 10 carbon atoms. The treated organic fibers, particularly in the form of textiles, exhibit a soft hand and good rewettability.
