Abstract

The invention relates to a slurry composition used for spinning, and a preparation method and application thereof. The composition is prepared in a way that an acrylic ester composition and nanometer SiO2 compound modified starch are mixed, wherein the acrylic ester composition is prepared from (A), (B), (C), (D) and (E); the (A) is (methyl) acrylate which are selected from (methyl) acrylate modified silicone oil, alkyl (methyl) acrylate having an alkyl of which the carbon number is 12 or above, and poly alkylene glycol alkyl (methyl) acrylate of which the number-average molecular weight is 400 or above, (B) is (methyl) acrylic compound which is subjected to ester bonding with alicyclic ring hydrocarbyl of which the carbon number is 6 or above, (C) is methacrylic acid-2-sulfonic acid ethyl ester, (D) is composite initiator and (E) is chain transfer agent; the nanometer SiO2 compound modified starch is prepared in a way that starch is subjected to acidification, crosslinking, oxidization, and the introduction of nanoscale SiO2 subjected to surface modification and ultrasonic dispersion. The slurry can obviously improve warp sizing performance and improve spinning efficiency, and can be widely suitable for the warp sizing of pure cotton, terylene, fiber and blended yarn.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a size composition for textiles, a preparation method and application thereof. Background technique [0002] There are four main types of size widely used for textile sizing: modified starch, polyvinyl alcohol, polyester and polyacrylate size. Modified starch sizing has good film-forming properties, strong affinity with natural fibers, and is easy to desizing. It is the main sizing component of textile sizing; not enough. Polyvinyl alcohol size film has high strength, good flexibility, and good slurry fluidity; however, polyvinyl alcohol is difficult to desizing, and because polyvinyl alcohol is difficult to degrade, it is easy to cause white environmental pollution, and the European Union has banned its use by legislation. The chemical structure of polyester size is similar to that of polyester, so it has strong affinity with polyester fiber, especially suitable for polyester...
