Abstract: A method for improving the elasticity of a textile material is provided wherein a preshrunk textile material, while maintained in a relaxed state, is impregnated with a liquid admixture consisting essentially of a polyisocyanate, a polyether diol, and a polyether polyol having at least three hydroxyl groups per molecule, reacting the polyisocyanate with the polyether diol and polyether polyol to provide a polymeric impregnated textile material, and curing the polymeric impregnated textile material to provide a textile material having improved elasticity.

Abstract: Fire retardancy and wrinkle resistance are imparted to cellulosic textiles by impregnation of said textiles with the phosphoalkylated reaction product of a polyisocyanate and an alkyleneamine.

Abstract: The addition of certain compounds -- namely mineral acids, oxidising agents, materials capable of producing these acids and agents, or mixtures of the same -- to BAPs or the corresponding mono-iso(thio)cyanate adducts renders these adducts more stable to storage and heat.

Abstract: A process for imparting durable flame-retardant properties to cellulosic fiber-containing materials without detrimentally affecting other properties (e.g., shrinkage, hand, etc.) of the material is disclosed. The material is contacted with cyanamide; at least one phosphonic acid represented by the structural formula: ##EQU1## wherein R.sup.1 represents a monovalent radical selected from the group consisting of hydrogen, halogen, hydroxy, lower alkyl and lower alkoxy, and wherein R.sup.2 represents a monovalent radical selected from the group consisting of hydrogen and lower alkyl; antimony oxide; and a polymeric halogen-containing material.

Abstract: The invention concerns new asymetrical distyrylbenzenes and a process for their preparation, these compounds having the formula ##SPC1##Wherein R.sub.1 and R.sub.2 can be identical or different from one another and denote hydrogen, chlorine or fluorine, lower alkyl or lower alkoxy groups, R.sub.a represents hydrogen, the nitrile group or a carboxyl group, its salts, esters or amides, M denotes a hydrogen, alkali, alkaline earth, ammonium or amine salt ion, m denotes the numbers 1 or 2 and n denotes the numbers 1, 2 or 3, with the proviso that I. at least one of the substituents R.sub.1, R.sub.2 and R.sub.a is different from hydrogen and II. in the case where R.sub.a is different from hydrogen, R.sub.2 represents hydrogen.The new compounds are valuable optical brightening agents, especially in combination with detergents.

Abstract: Textile treating compositions containing the elements phosphorus, nitrogen, and bromine and the processes for imparting flame resistance to organic fibrous materials have been prepared. This is accomplished by impregnating the textile treating compositions consisting of (1) tris(hydroxymethyl)phosphine mixed with nitrogenous compounds containing at least two members of the group hydrogen and methylol radicals (--CH.sub.2 OH) attached to trivalent nitrogen atoms, or (2) soluble methylol phosphine adducts which contain one or more methylol phosphine radicals (P--CH.sub.2 OH) prepared by reacting tris(hydroxymethyl)phosphine with an amide or amine which contains one or more hydrogens attached to a trivalent nitrogen with an organic bromine containing material with at least 10% bromine in the form of bromine atoms attached to carbon atoms, in proportions selected so that generally the phosphorus contained in structures of the group (--CH.sub.2).sub.

Abstract: A paperboard impregnated with polyurethane resin having specific NCO content and average molecular weight at the rate of 0.05 to 5.0 weight percent relative to the paperboard has excellent mechanical properties such as compressive strength, tensile strength, tearing strength, folding endurance, etc., even in wet state.

Abstract: The present invention relates to a process for sizing cellulose fibers or cellulose fiber containing materials and a composition for carrying out the process. According to the process the time for developing full sizing effect of ketene dimers and carbamoyl chlorides is reduced by carrying out sizing in the presence of a chloroformate or an isocyanate. The composition for carrying out the process comprises of a paper sizing composition containing the sizing agents mentioned above in combination with a chloroformate or an isocyanate.
