Abstract

The invention relates to a spinning sizing agent composition and a preparing method and application thereof. The composition is prepared by mixing an acrylate composition and a nanometer SiO2 composite modified starch, wherein the acrylate composition is prepared from a (methyl) acrylate compound selected from one or more of (methyl) acrylate-modified silicone oil, alkyl (methyl) acrylate with alkyl with the number of carbon atoms being 12 or above and poly alkylene glycol (methyl) acrylate with the number-average molecular weight being 400 or above, a (methyl) acrylate compound in ester linkage with alicyclic alkyl with the number of carbon atoms being 6 or above, acrylonitrile, a composite initiator and a chain transfer agent, and the nanometer SiO2 composite modified starch is obtained by carrying out acidification, cross-linking and oxidation on starch, introducing surface-modified nano-scale SiO2 and then carrying out ultrasonic dispersing. The sizing agent can remarkably improve the sizing performance of warp yarns and the spinning efficiency and can be widely applied to sizing of warp yarns made of pure cotton, polyamide, fibers and blended yarns.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a textile slurry composition and 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...
