Abstract

The invention relates to textile sizing agent composition used for a polyester fabric as well as a preparation method and an application of the textile sizing agent composition. The composition is formed by mixing acrylate composition with nano SiO2 composite modified starch, wherein the acrylate composition consists of (A) a (methyl) acrylate compound selected from one or more of (methyl) acrylate modified silicone oil, alkyl (methyl) acrylate with alkyl with more than 12 carbon atoms and polyalkylene glycol (methyl) acrylate with the number-average molecular weight of more than 400, (B) a (methyl) acrylate compound with ester bonded with alicyclic alkyl with more than 6 carbon atoms, (C) acrylonitrile, (D) a composite initiator and (E) a chain transfer agent; and the nano SiO2 composite modified starch is prepared by acidifying, cross-linking and oxidizing starch, introducing nano SiO2 subjected to surface modification and performing ultrasonic dispersion. The sizing agent is capable of remarkably improving the warp sizing performance and the spinning efficiency, thereby being suitable for warp sizing of the polyester fabric.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a textile size composition for polyester fabrics, 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 suita...
