Abstract

The invention provides a textile size combination which is prepared by mixing solid acrylate with nano SiO2 compound modified starch in proportion, wherein the solid acrylate is prepared by the following steps: mixing acrylonitrile, methyl acrylate, butyl acrylate, methyl methacrylate, acroleic acid, methacrylic acid with acrylamide in proportion, and enabling the mixed solvent to be subject to internal polymerization under the action of compound initiator and chain transfer agent, neutralizing with sodium hydroxide and drying; and the nano SiO2 compound modified starch is prepared by the following steps: sequentially acidifying, crosslinking and oxidizing starch, introducing surface-modified nano-level SiO2 and carrying out ultrasonic dispersion. The size can obviously improve the warp sizing performance and improve the weaving efficiency, can be completely replace PVA and imported sizes in the same amount or partial amount, and is widely used for the warp sizing of purified cotton, terylens, novel fibers and mixed yarns of various counts.

Description

technical field [0001] The invention relates to a sizing material used in the weaving process of textiles, in particular to a textile size composition. 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 fiber, and its desizing ...
