Problems solved by technology

[0006] Both of these patented products are synthesized by chemical reaction and copolymerization by adding non-polar nano-materials during the reaction process of producing polyacrylic acid slurry. Not only the manufacturing process is complicated, but the use is inconvenient, and the above-mentioned patents are only based on laboratory test data to illustrate The purpose of replacing PVA size, and textile warp sizing is an important link in textile mills. The sizing process is the most complicated, and the selection of size is very strict. If the quality of the size is unqualified, it will cause major damage to the textile mill. loss

Embodiment 1

[0030] In the first embodiment, 2%-8% of the total weight of the ultrafine inorganic material, 20%-30% of the polyacrylic acid slurry and the balance of water are mixed. Among them, the ultrafine inorganic material is powder SiO 2 , The particle size is 10nm-1um, the solid content is 90%-95%, the polyacrylic acid slurry is a granular powder made of acrylamide, acrylonitrile, and vinyl acetate, and the solid content is 90%-95%.

[0031] Since the existing ultrafine inorganic materials and polyacrylic slurries can be divided into liquid and solid forms according to the different solid content, no matter which one you choose, as long as the ratio of the effective ingredients of the ultrafine inorganic materials to the total weight is 1 %-10%, the proportion of the polyacrylic acid slurry to the total weight is 10%-40%.

Embodiment 2

[0032] In the second embodiment, 5%-40% of the total weight of the ultrafine inorganic material, 60%-90% of the polyacrylic acid slurry and the balance of water are mixed. Among them, the ultrafine inorganic material is SiO 2 , TiO 2 And Al 2 O 3The compound is milky white liquid with a particle size of 10nm-1um and a solid content of 10%-50%. The polyacrylic acid slurry is prepared by emulsion copolymerization of acrylamide, butyl methacrylate and styrene with water as a solvent. It becomes a viscous liquid with a solid content of 10%-50%.

Embodiment 3

[0033] In the third embodiment, 5%-40% of the total weight of the ultrafine inorganic material, 10%-30% of the polyacrylic acid slurry and water are mixed. Among them, the ultrafine inorganic material is Al 2 O 3 And TiO 2 The mixture, the appearance is milky white liquid, the particle size is 10nm-1um, the solid content is 10%-50%; the polyacrylic acid slurry is a granular powder made of acrylic acid, acrylamide, acrylonitrile, and vinyl acetate. The solid content is 90%-95%.

Abstract

The invention provides an environment-friendly textile size composition which has simple process and convenient use, and substitutes for polyvinyl alcohol, and a preparation method thereof, which aim at the current status that the sizing of the prior textile fiber warp can not be independent from PVA size and the disadvantages of the prior size. The size composition is prepared by mixing an ultrafine particle inorganic material which accounts for 1 to 10 percent of the total weight, polyacrylic acid size which accounts for 10 to 40 percent of the total weight, and water for the balance. The size composition is matched with modified starch size, can fully substitute for the PVA size during the sizing process of yarns such as pure cotton, polyester cotton, hemp, artificial cotton, and tenel, and meet the manufacturing requirement of high-difficulty varieties.

Description

Technical field [0001] The invention belongs to the field of polymer materials and relates to an environmentally friendly textile slurry that replaces polyvinyl alcohol in textile fiber sizing and a preparation method thereof. Background technique [0002] Polyvinyl alcohol (PVA) is the main sizing agent used for warp yarn sizing in the textile industry. It is considered to be ideal due to its excellent film-forming properties, adhesion, wear resistance and good compatibility with other sizing agents. Sizing, especially for warp sizing on difficult varieties of high-speed shuttleless looms, is inseparable from PVA sizing. However, with the strengthening of environmental protection awareness, in recent years, developed countries, especially Western European countries, have proposed a ban on the use of PVA as textile slurry and the import of gray fabrics containing PVA in response to the current situation that PVA slurry is difficult to biodegrade and causes serious pollution ...
