Embodiment Construction

[0021] Below in conjunction with specific embodiment, the present invention is described in further detail:

[0022] A preparation process of polyester fabric, which is carried out as follows: polyester gray cloth→alkali weight reduction treatment→dyeing and flame-retardant finishing→drying→baking→washing→drying, wherein:

[0023] The dyeing and flame-retardant finishing includes (1) treating the polyester base fabric that has undergone alkali weight reduction treatment by means of two dipping and two-rolling, and controlling the excess rate of 50% to 70%. The bath for dyeing and flame-retardant finishing The pH of the solution is about 5, the bath ratio is 1:18-22, and it contains the following components: disperse dye X; flame retardant (SAF8078 phosphorus flame retardant, Hutt Group) 10%-20% (weight content); dispersant (Dispersant NNO, Shanghai General Reagent Factory) 1.7~2.5g / l; Penetrant (JFC) 1.7~2.5g / l. (2) Coating and flame-retardant treatment is carried out on the ...

Abstract

The invention relates to a process for preparing polyester fabrics, which comprises the steps of gray polyester fabric selection, alkali deweighting finishing, dyeing and antiflaming processing, drying, baking, washing and drying, wherein the dyeing and the antiflaming processing are in same bath fluid, and the bath ratio of the two is 1: (18 to 22); a way of soaking gray polyester fabrics for two times and rolling the gray polyester fabrics for two times is adopted, and the liquid retention is 50 to 70 percent; the pH value of the bath fluid for dyeing and antiflaming processing is 3 to 6.5, and the bath fluid comprises the following compositions: disperse dyes X, 10 to 20 percent of flame retardant (weight content), 1.7 to 2.5 g / l of dispersing agent, and 1.7 to 2.5 g / l of penetrating agent, wherein the flame retardant is phosphorus flame retardant. The polyester fabrics prepared by using the process of the invention have the advantages of good flame-retardant performance and low temperature resistance (- 43 DEG C), and meet the requirements for clothing performance in the military field and the entertainment items such as climbing and skiing and the like. In addition, the process of the invention is simple, and easy to operate.

Description

technical field [0001] The invention relates to a preparation process of polyester fabric. Background technique [0002] Polyester fabric is a kind of chemical fiber clothing fabric widely used in daily life. Its biggest advantage is that it has good wrinkle resistance and shape retention, so it is suitable for outerwear. Generally, the characteristics of polyester fabrics are as follows: polyester fabrics have high strength and elastic recovery ability, so they are durable, wrinkle-resistant and non-ironing; polyester fabrics have poor hygroscopicity, feel stuffy when worn, and are prone to static electricity and stains Dust affects the appearance and comfort, but it is very easy to dry after washing, and the wet strength hardly decreases, does not deform, and has good washability and wearability; polyester is the best heat-resistant fabric among synthetic fabrics, with thermoplasticity, Creates pleated skirts with long-lasting pleats. At the same time, polyester fabrics...
