Problems solved by technology

[0002] As we all know, polyester fiber is poor in fluffy softness, moisture absorption and perspiration, antistatic performance, and easy decontamination performance.
Therefore, the textiles processed with polyester fibers have poor wearability and are prone to static electricity, which has caused certain harm to the health of the human body. Although the modified agent can also modify polyester fibers, it will become invalid after 5 to 10 times of washing.

Abstract

The invention relates to a washing-resistant agent used for polyester fiber, and a preparation method thereof. The washing-resistant agent comprises the components of, by weight: 60-160 parts of polyethylene glycol, 13-40 parts of glycol, 14-26 parts of dimethyl terephthalate, 15-100 parts of polyamide, and 0.2-1 parts of metal acetate as a catalyst. The washing-resistant agent provided by the invention can be used for modifying polyester fiber. Modified polyester fiber has fluffy and soft texture, antistatic property, hydrophilic smoothness, and the like. The modification agent has excellent washing resistance, and does not fail for at least 30 times of washing.
