Abstract

The invention relates to a hydrophobic stiffening agent and a preparation method and a use method thereof. The hydrophobic stiffening agent is prepared from the following raw materials and components in percentage by weight: 2 to 5% of dispersive stabilizer, 45 to 50% of comonomer, 0.05 to 0.3% of initiator, 0.4 to 1% of adjusting acid, 0.1 to 0.6% of neutralizing alkaline, and 43 to 53% of deionized water.

Description

technical field [0001] The invention belongs to dyeing and finishing auxiliaries of textile products, and in particular relates to a hydrophobic stiffening agent and a preparation method and a use method thereof. Background technique [0002] Stiffening agent refers to a kind of textile auxiliary agent used for stiffening and finishing of textiles. Its main function is to improve the appearance of textiles, increase the elasticity and fullness of textiles, and endow textiles with stiffness, so that textiles can obtain rigidity, stiffness, elasticity, Thick feel. It has a wide range of applications in the textile industry, and can be used in curtains, mosquito nets, bags, tooling, interlinings and non-woven fabrics, etc. [0003] At present, the common stiffening agent products on the market mainly include: [0004] (1) Thermosetting type: such as (etherified) melamine resin, urea aldehyde resin, etc.; [0005] (2) Thermoplastic type: such as polyacrylate emulsion, polysty...
