Problems solved by technology

[0004] Since the German Gminder company developed a water-soluble cold size (it can be easily desized at neutral and 40°C) with a PVA-based copolymer as the main component in 2007, it has been reported that (CN103498340) is used for cotton spinning and wool spinning. Cold slurry agent, the main components of this cold slurry agent are emulsifier, methyl acrylate and acrylic acid, etc., with a solid content of about 55%, which has the disadvantages of high cost and easy pollution and yellowing of spinning yarn after desizing; and in its preparation During the process, acrylate, acrylic acid and other monomers and initiators introduce acrylate polymerization components through chemical reactions, which brings stability risks to product quality
Although acrylate polymers have the advantages of excellent weather resistance, film-forming properties and decorative properties, rich sources of raw materials and easy production and implementation, and some new acrylate materials have achieved certain results in some cold pastes, but acrylates The "cold brittle and hot sticky" property of polymers limits its application, and there are many difficulties in its promotion and application
Fu Xiurong and others used acrylic acid and modified starch as the main raw materials to prepare cold sizing agent (Proceedings of the Second National Wool Spinning Industry Technical Transformation Symposium of "Dekai Cup", 248-255). And it is not easy to degrade and will seriously pollute the environment

Abstract

The invention relates to an efficient cold sizing agent containing polysiloxane acrylate and a preparation method of the efficient cold sizing agent. The efficient cold sizing agent containing the polysiloxane acrylate comprises the following components in parts by mass: 52 to 69 parts of water, 2 to 4 parts of the polysiloxane acrylate, 7 to 10 parts of an emulsifier EL-40, 10 to 13 parts of an emulsifier TX-12, 3 to 6 parts of fatty alcohol-polyoxyethylene ether, 4 to 7 parts of a plasticizer and 5 to 8 parts of coconut oil fatty acid diethanolamide. The efficient cold sizing agent is colorless transparent viscous liquid and is in a nonionic state, the pH value is 6-8, the viscosity is 130-200 mps.s under the condition of 25 DEG C, the excellent permeability and antistatic property are achieved, the efficient cold sizing agent is suitable for cotton spinning and chemical fibers and is also suitable for pure cotton and wool blended yarns, the weaving function of spun yarns can be transformed, the cost is low, the efficient cold sizing agent is green, environment-friendly and degradable, and the efficient cold sizing agent can be widely applied to the technical field of sizing agents for textile warp sizing.

Description

technical field [0001] The present invention relates to a kind of sizing material for textile warp yarn sizing, in particular to a high-efficiency cooling sizing agent containing polysiloxane acrylate for cotton-spun wool-spun chemical fibers suitable for sizing pure wool and wool blended yarns and a preparation method thereof. Background technique [0002] In the textile industry, sizing agent is an important textile auxiliary. Basically all are to add quantitative polyvinyl alcohol (PVB) after mixing with starch or modified starch at present, boil sizing. The above-mentioned sizing agent not only consumes heat in the sizing process, but also has high requirements on the sizing process equipment. It is urgent to find a special sizing agent that can improve the lubricating performance of the warp at room temperature without drying and drying. question. [0003] Cold sizing is a warp preparation technique that is sized at room temperature with liquid size aids without dryin...
