Post-treatment method for comfortable and cool terylene silk-like fabric

Abstract

The invention discloses a post-treatment method for a comfortable and cool terylene silk-like fabric. The method includes steps of desizing, alkali decrement treatment on a base fabric and padding finishing. In the step of alkali decrement treatment on the base fabric, a treatment solution includes components of, by weight, 2-3% of caustic soda, 0.15-0.25% of penetrating agent, 0.15-0.25% of scouring agent, and the balance of water; a bath ratio is 1:15-20; a treatment temperature is 120+ / -5 DEG C; a treatment time is 40+ / -3min; and a reduction rate is 10-12%. Adoption of the method in the invention to prepare terylene fabric overcomes the hard handle of terylene fabric, improves wearing conformability of polyester fabric; and the product has the advantages of convenient processing and high resource utilization rate.

Description

[0001] This application is a divisional application of the invention patent application (application number 201010528042.4) filed on November 1, 2010, entitled "Finishing agent for polyester imitation silk fabric and its preparation and post-treatment method". technical field

[0002] The invention relates to a finishing agent for polyester imitation silk fabrics, a preparation method thereof and a post-treatment method for polyester imitation silk fabrics. Background technique

[0003] Polyester fabrics have incomparable excellent properties of natural fibers such as high strength, wear resistance, good wrinkle resistance, no insects, quick drying, and easy care. However, it has low moisture regain, poor moisture absorption and vapor permeability, stuffy clothes, easy to generate static electricity, easy to absorb dirt and breed bacteria. Therefore, the wearing comfort of polyester fabric is poor.

[0004] The shortcomings of polyester fabrics can be improved by chemical f...
