Title: A process for the treatment of yarns and threads
IPC: D06M15/564
Filed: 1957-02-12
Abstract: Fully synthetic yarns or threads for use in the production of knotted fabrics, e.g. nets, are given a reduced tendency to slip by treatment with a solution containing (1) a diisocyanate and/or a polyisocyanate and (2) a dihydroxy and/or polyhydroxy compound with a molecular weight of at least 500, followed by after-treatment at an elevated temperature.  The threads or yarns may be composed of polyamides, polyurethanes, polyesters or acrylonitrile.  Isocyanates specified include 1,2,4-toluylene diisocyanate, m-phenylene diisocyanate, dimethyl-diphenyl methane-4,41-diisocyanate, reaction products containing isocyanate groups obtained from di-isocyanates and less than the stoichiometric amount of polyhydroxy compounds such as glycol, glycerol, trimethylol propane or hexanetriol, and compounds which, under the influence of heat, split into an isocyanate and the relevant addition components, e.g. hydrocyanic acid, phenol, or malonic or acetoacetic acid ethyl ester.  The polyhydroxy compounds include polyesters produced by esterifying dicarboxylic acids with an excess of di- and/or polyalcohols in the presence or absence of hydroxycarboxylic acids, e.g. citric acid; polyester amides with terminal hydroxyl groups obtained by the esterification of dicarboxylic acids with an excess of di- and/or polyalcohols in the presence of amino alcohols, e.g. di-ethanolamine; polyethers and polythioethers containing terminal hydroxy groups, and polyesters of phthalic acid and glycerol modified with fatty acids.  The compounds may be applied in solutions in ethyl acetate, acetone or tetrahydrofurane which may contain catalysts, e.g. tertiary amines or iron acetylacetonate.  The coated threads may be passed through a chamber heated to 200 DEG  C. at a speed such that the thread temperature does not exceed 120 DEG  C.  In Examples: (1) a polyamide cable, after being coated with an ethyl acetate solution containing a polyester produced from adipic acid, trimethylol propane and butylene glycol, a polyester produced from adipic acid, trimethylol propane and diethylene glycol, the reaction product of toluylene di-isocyanate and hexanetriol, and iron acetylacetonate, is passed rapidly through a closed tube through which air heated to 190 DEG  C. is blown and is wound under tension; (5) in a similar process, the coating composition comprises an ethyl acetate solution containing a branched polythioether produced from thiodiglycol, butylene glycol, bis - hydroxyethyl diphenyl - dimethylmethane and trimethylol propane, a linear polythioether produced from thiodiglycol and butanediol and a reaction product of dimethyl - diphenyl methane-4,41-diisocyanate and hexanetriol.
