Embodiment 1

[0028] A preparation method for sizing slurry for poplin compact fabrics. Polyoxyethylene, polyoxypropylene ether, polyacrylamide, double rhamnolipid and sizing paste are added to a mixer equipped with a stirrer, a thermometer and a reflux condenser. In the flask, add deionized water and sodium taurine, raise the temperature to 85°C, pass through nitrogen protection, stir for 40-50min, then slowly add citric acid dropwise, the dropwise addition is completed in about 2h, after keeping warm for 2h, add PMA slurry and lauryl alcohol Polyoxyethylene ether, ethanol, and then react for 9-12h, and cool to room temperature to obtain the size for poplin compact fabric sizing;

[0029] The specific component content of the slurry for sizing is as follows in parts by weight:

[0030] Polyoxyethylene 20

[0031] Polyoxypropylene ether 15

Abstract

The invention relates to a method for preparing a sizing agent for sizing of poplin type tightly-woven fabric fiber. According to the method, polyoxyethylene, polyoxypropylene ether, polyacrylamide, di-rhamnolipid and sizing paste are added to a flask containing a stirrer, a thermometer and a reflux condensing tube, deionized water and taurine are added, temperature is increased to 85 DEG C, nitrogen is introduced for protection, stirring is conducted for 40-50 min, citric acid is slowly added for about 2 h, heat preservation is conducted for 2 h, then a PMA sizing agent, laurinol polyoxyethylene ether and ethanol are added for reaction for 9-12 h, temperature is lowered to indoor temperature, and then the sizing agent for sizing of the poplin type tightly-woven fabric is obtained. The sizing agent prepared with the method has high fiber adhesive force and high cohesive force after sizing is conducted, and fiber fuzzing can be prevented through a surface film formed on the surface of the fiber; furthermore, decoating or reduction of fiber strength caused by friction is avoided, fiber strength can be improved, and meanwhile, the elasticity, flexibility and extensibility of the fiber are maintained.

Description

technical field [0001] The invention relates to a preparation method of a textile sizing agent, in particular to a preparation method of a size material for sizing poplin compact fabrics. Background technique [0002] In the textile industry, sizing agent is an important textile auxiliary. At present, starch or modified starch is basically added with a certain amount of polyvinyl alcohol (PVA) for mixing, and then boiled for sizing. The above-mentioned sizing agent foams greatly when the polyvinyl alcohol PVA is desized, is not easy to degrade, and will seriously pollute the environment. At present, if purely modified starch or starch is used for sizing, no matter the adhesion to the line, or the breaking strength of the size film, the elongation at break of the size film, and the abrasion resistance, etc., cannot meet the standard requirements. [0003] The research on sizing agents abroad has been relatively mature, and there is a certain gap in domestic development. Mo...
