Embodiment 1

[0037] refer to figure 1 , this embodiment discloses a dyeing process of polyester cloth, the polyester gray cloth is carried out as follows:

[0038] S1: pre-processing. Firstly, the polyester gray cloth is sent to the setting machine for presetting, and the setting temperature in the setting machine is adjusted to 190°C, and the presetting is continued for 15 minutes, and then the polyester gray cloth is cooled to room temperature. Then, the pre-shaped gray cloth is transported to the padding machine, and the desizing liquid is added. The material composition of the desizing liquid includes 28 g / L of caustic soda and 9 g / L of oil-removing refining agent. When adding, first add caustic soda to the padding machine and stir for 25 minutes; then add oil-removing refining agent to the padding machine, control the bath ratio of 1:25, and stir for 40 minutes; then pad the polyester gray cloth in the padding machine for 5 hours. After padding in the padding machine for 5 hours, th...

Embodiment 2

[0049] The difference between embodiment 2 and embodiment 1 is: in S2 dyeing, the dispersant in the dyestuff is the mixture of sodium dodecylbenzenesulfonate, sodium succinate and dicetyl phosphate aluminum, and the weight ratio of the three It is 10:3:4.

Embodiment 3

[0050] The difference between Example 3 and Example 1 is that in S2 dyeing, the dispersant in the dye is dispersant MF.

Abstract

The application relates to the technical field of fabric dyeing and finishing, and discloses a dyeing process for polyester fabrics. A polyester grey fabric is subjected to the following operations: S1: pretreatment; S2: dyeing, namely, dyeing the grey fabric after the treatment in S1, wherein a dye used for dyeing comprises the following components in parts by weight: 20-40 parts of a disperse dye, 13-27 parts of a dispersant, 4-10 parts of 2,3-butanediol, 5-14 parts of cetyl ethyl hexanoate, 3-19 parts of carboxymethyl cellulose acetate butyrate, 20-40 parts of hydroxyethylidene diphosphonicacid, 20-40 parts of octadecylisocyanate, 3-9 parts of acetic acid and 230-310 parts of water; S3: continuous cleaning, namely, continuously cleaning the grey fabric after the treatment in S2; S4: dehydration; S5: scutching; and S6: setting; and the grey fabric after the setting in S6 is a dyed polyester fabric. The color fastness of polyester fabric dyeing can be improved.

Description

technical field [0001] This application relates to the field of cloth dyeing and finishing, in particular to a dyeing process of polyester cloth. Background technique [0002] Polyester, scientific name, polyester fiber, is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, referred to as PET fiber, which belongs to polymer compounds. It belongs to the largest variety of synthetic fibers at present. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery ability. It is strong and durable, anti-wrinkle and non-ironing, and non-sticky. [0003] Common polyester fibers are hydrophobic fibers made from polyethylene terephthalate. Due to the tight molecular chain structure of polyester and the lack of hydrophilic groups such as carboxyl and sulfonic acid groups, direct dyes, acid dyes, and basic dyes cannot be used for ...
