Abstract

The invention relates to an in-bath crease-resisting agent used in polyester fiber fabric, and a preparation method thereof. The agent comprises the following components, by weight: 2-5% of a polyester-polyether-silicon oil block copolymer, 1-5% of sorbitan 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 in-bath crease-resisting agent provided by the invention, good crease-resisting effect of the polyester fiber fabric is provided, and excellent fluffy and soft texture, good antistatic property, and good hydrophilic smoothness are provided with dyed polyester fiber fabric. Dyed polyester fiber or fabric thereof can be provided with excellent comfortableness without other finishing.

Description

technical field [0001] The invention relates to an in-bath anti-wrinkle agent, in particular to an in-bath anti-wrinkle agent for polyester fabrics 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 polyester fiber fabrics, in order to avoid wrinkles in the dyeing and post-treatment process of the fabric and effectively prevent wrinkles, an anti-wrinkle ag...
