Problems solved by technology

However, the existing leveling agent only has a leveling effect and does not have other finishing effects
For polyester fibers or their fabrics, it is necessary to carry out antistatic finishing such as antistatic, fluffy and soft after the dyeing is completed, so that the production process is more complicated and the cost is higher

Abstract

The invention relates to a high-temperature leveling agent, and a preparation method and an application thereof. The high-temperature leveling agent is prepared from 0.1-1% of a polyester-polyether-silicon oil block copolymer, 9-10% of polyethylene glycol monostearate, and balance of water. The polyester-polyether-silicon oil block copolymer is prepared from the raw materials of, by weight: 120-160 parts of polyethylene glycol, 18-30 parts of glycol, 15-25 parts of dihydroxy polyether, 20-28 parts of dimethyl terephthalate, 10-30 parts of an amino-terminated double-head sealant organosilicon, 5-10 parts of 3-piperazine propyl dimethoxysilane, and 0.2-2 parts of metal acetate. With the high-temperature leveling agent provided by the invention, dyeing quality of polyester fiber or fabric thereof can be improved, and the dyed polyester fiber or fabric thereof is provided with excellent fluffy and soft property, good antistatic performance, and good hydrophilic property. The dyed polyester or fiber thereof can be provided with excellent comfortableness with no other finishing.

Description

technical field [0001] The invention relates to the technical field of fabric finishing agents, in particular to a high-temperature leveling agent and a preparation method thereof. Background technique [0002] As we all know, polyester fiber has poor fluffy softness, moisture absorption and perspiration, antistatic performance and easy decontamination performance. Therefore, the textiles processed with polyester fibers have poor wearability, are easy to stick to dirt, and are prone to static electricity. This will undoubtedly cause certain harm to human health. In order to overcome the shortcomings of polyester fiber and to meet the increasingly high requirements of the market for textiles, polyester fiber must be finished in order to improve its performance. [0003] It is also known that in the dyeing process of fiber yarns, threads or fabrics, it is often necessary to add a leveling agent in order to promote uniform dyeing and avoid defects such as color stripes and st...
