Preparation process of polyester fabric

Abstract

The invention discloses a preparation process of a polyester fabric. The preparation process comprises the following steps: preparing a polyester gray fabric, performing alkali weight reducing treatment, dyeing, performing flame retardant finishing, drying, baking, washing with water and drying; performing dyeing and flame retardant finishing in one bath in the bath ratio of 2:25 at the temperature of 115-120 DEG C in a two-dipping and two-rolling way, wherein the rolling excess rate is 75-80 percent, the pH of the bath foam is 6.6-6.8, and the bath foam comprises a 30-35 weight percent phosphorus based flame retardant, a 3-4 g / L hexyldecanol, 35-40 g / L disperse dyes, 2-3 g / L hydroxyethyl cellulose and a 6-7 g / L penetrating agent; and performing coating and flame retardant treatment on the cloth which undergoes the two-dipping and two-rolling treatment. According to the preparation process of the polyester fabric provided by the invention, the defects of easiness in ageing and cracking at a low temperature and no flame retardant function existing in the polyester fabric are overcome.

Description

technical field

[0001] The invention relates to a preparation process of polyester fabric. Background technique

[0002] Currently commonly used polyester fabrics for clothing are prone to aging and splitting at low temperatures, and have no flame retardant function. Contents of the invention

[0003] The object of the present invention is to provide a preparation process of polyester fabrics to overcome the disadvantages of polyester fabrics being easy to age, split and have no flame-retardant function at low temperature.

[0004] In order to achieve the above object, the technical solution of the present invention is to design a preparation process of polyester fabric, comprising the steps of:

[0005] Preparation of polyester gray fabric, alkali weight reduction treatment, dyeing and flame retardant finishing, drying, baking, washing and drying;

[0006] Dyeing and flame retardant finishing are carried out in the same bath, the bath ratio is 2:25, the temperature is 1...
