Problems solved by technology

The solid content of polyacrylic acid emulsion is only 25%, and the transportation cost is high; and the presence of emulsifiers often deteriorates its performance, such as producing foam and affecting its compatibility with other types of slurries, etc.
Solid acrylic paste is more popular, but the solid acrylic paste on the market absorbs moisture and sticks again seriously, and the strength of the paste film is not enough
Therefore, neither polyacrylic acid emulsion nor solid acrylate can completely replace polyvinyl alcohol.
[0003] Using the existing size sizing method, the existing size must be above 90°C when sizing, to prevent the viscosity increase after the temperature drops from affecting the sizing quality, and also prevent many sizing defects s

Abstract

The invention relates to textile a sizing agent and a preparation method thereof. The textile sizing agent comprises, by mass percentage, 82-88% of main materials and 12-18% of auxiliaries. The main materials comprise nano silicon dioxide modified starch, pea starch, phosphate starch, acrylic acid, butyl acrylate, acrylamide, sodium sulfamate, diphenylmethane and protein amino acid. The auxiliaries comprise methyl alcohol, 2-naphthol, monochloroacetic acid and NaOH. The preparation method of the textile sizing includes the steps that firstly, the main materials are prepared; secondly, the main materials and the auxiliaries are evenly mixed to obtain the textile sizing agent. When the textile sizing agent is used for sizing, textiles can be subjected to sizing in the temperature range of 25-28 DEG C; after sizing, yarn is stable in performance, and strength and wear resistance are enhanced.

Description

technical field [0001] The invention relates to the technical field of textile sizing, in particular to a textile size and a preparation method 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 fiber, and its desizing...
