Environmentally-friendly textile sizing agent and preparation method thereof

Abstract

The invention discloses an environmentally-friendly textile sizing agent and a preparation method thereof. The environmentally-friendly textile sizing agent is prepared from the following components:3 to 9 parts of chitosan, 2 to 8 parts of a crease resistant agent, 15 to 20 parts of maleic anhydride, 2 to 6 parts of dibutyl diacrylate, 0.5 to 1.5 parts of bentonite, 2 to 6 parts of waterborne copolymer ether ester, 5 to 12 parts of acetylated distarch adipate, 5 to 15 parts of acrylamide, 4 to 9 parts of butyl acrylate, 2 to 6 parts of vinyl acetate, 1 to 2 parts of an initiator, 0.8 to 1.5parts of a catalyst, 2 to 6 parts of calcium chloride, 5 to 10 parts of deionized water and 5 to 10 parts of modified starch. By adding the chitosan and the modified starch, textile fiber can be effectively puffed and loosened, so that the sizing percentage of a fabric is increased; by adding the bentonite, the intensity and the toughness of a sizing film can be greatly improved. By reasonable control over the contents of all the components of the sizing agent and preparation process conditions, the prepared textile sizing agent is stable in viscosity, excellent in chemical stability and thermal stability, and easy to size and desize; sizing agent wastewater is easy to treat; the sizing film performance and the sizing performance are high; the hygroscopic reviscosity is low; the environmentally-friendly textile sizing agent is green and environmentally friendly, and can avoid environmental pollution.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an environment-friendly textile slurry and a preparation method thereof. Background technique [0002] With the continuous development of the national economy, modern people have higher and higher requirements for textile products, and more stringent requirements for the experience of use. The textile size coats the surface of the yarn with a layer of smooth, wear-resistant and flexible And there is a certain strength of the sizing film, which makes the overall sliver tighter, reduces the friction coefficient on the surface of the sliver, and at the same time allows part of the sizing to penetrate into the interior of the yarn, increasing the adhesion between fibers and improving the tensile strength of the yarn , to adapt to the large tension and medium beating in the textile manufacturing process, reduce broken ends and improve efficiency. At present, there are three main typ...
