Problems solved by technology

[0003] In the existing technology, the processing flow of the traditional process for PBT fabrics is: overflow preshrinking → dehydration → opening width → high temperature reservation → dyeing → dehydration → opening width → drying → finishing → finished product rolling, the processing flow is relatively Long, low production efficiency, high energy consumption, high cost

Embodiment 1

[0020] Embodiment 1: as attached figure 1 As shown, a new PBT fabric processing technology, the process is open-width pre-shrinking → dyeing → dehydration → opening → finishing → finished product rolling, the specific steps are as follows:

[0021] (1) Open-width pre-shrinking process: use an open-width washing machine, which is divided into seven washing boxes, and the temperature of each washing box is set at 40°C → 50°C → 60°C → 90°C → 90°C ℃→70℃→40℃, add 2.0g / L degreaser to the washing box in the first two sections, adjust the pH value to about 5.5, the water temperature in the washing box in the third and fourth sections will gradually increase, and the fabric width will further return shrink, and wash off the oil stains on the cloth surface by means of hot water spray and overflow out of the third and fourth sections of the washing tank, and the temperature of the last three sections of the washing box gradually decreases;

[0022] (2) Dyeing process: after being pre-sh...

Embodiment 2

[0027] Embodiment 2: as attached figure 1 As shown, a new PBT fabric processing technology, the process is open-width pre-shrinking → dyeing → dehydration → opening → finishing → finished product rolling, the specific steps are as follows:

[0028] (1) Open-width pre-shrinking process: use an open-width washing machine, which is divided into seven washing boxes, and the temperature of each washing box is set at 40°C → 50°C → 60°C → 90°C → 90°C ℃→70℃→40℃, add 3.0g / L degreaser to the washing box in the first two sections, adjust the pH value to about 5.5, the water temperature in the washing box in the third and fourth sections will gradually increase, and the fabric width will further return shrink, and wash off the oil stains on the cloth surface by means of hot water spray and overflow out of the third and fourth sections of the washing tank, and the temperature of the last three sections of the washing box gradually decreases;

Abstract

The invention discloses a brand new PBT fabric processing process. The brand new PBT fabric processing process includes: performing open-width preshrinking; dyeing; dewatering; scutching; finishing; rolling finished products. The brand new PBT fabric processing process has the advantages that the PBT fabric processing process flow is simplified greatly, and smoothness in processing is achieved; overall processing steps are reduced, processing time is shortened, and accordingly production efficiency can be increased; the use amount of water, electricity and gas is reduced, and sewage dischargequantity is lowered; in the dyeing step, fabric color yield is increased, the use amount of dye for acquiring the same color can be reduced as compared with a conventional processing process, and dyecost is further saved; the finishing step allows the fabric to further acquire elasticity, the stretching resilience of the fabric is increased, and garment wearing comfortableness is further increased.

Description

technical field [0001] The invention relates to a fabric processing technology, in particular to a brand-new PBT fabric processing technology. Background technique [0002] The chemical name of PBT (Polybozothiazole) is polybutylene terephthalate, which is formed by polycondensation of dimethyl terephthalate (DMT) or terephthalic acid (TPA) and butanediol after esterification. This is a new type of polyester fiber that was born recently. Because PBT fiber has the characteristics of good elasticity, high dyeing rate, and good color fastness, it also maintains the washable, crisp, and stable dimensions of ordinary polyester (PET). Therefore, PBT fiber has developed rapidly at home and abroad in recent years. Because the flexible part of the basic chain link of PBT macromolecules is longer, the melting point and glass transition temperature of PBT fibers are lower than those of ordinary polyester fibers, and the flexibility and elasticity of fiber macromolecular chains are imp...
