Embodiment 1

[0018] Example 1: cold stack

[0019] Process prescription (g / L) and conditions are as follows:

[0020]

[0021] In the above process, the chelating dispersant TF-510C can prevent equipment and fabrics from being stained, has the functions of scale inhibition and scale removal, and has good compatibility with desizing liquid. Used in combination with Quyouling TF-104, it has good dispersing and emulsifying effects on spandex oil and silicon-containing additives, strong detergency, and desizing, scouring and cleaning functions.

[0022] Low tension during the cold stacking process, the fibers can fully swell and release the internal stress generated during spinning and weaving, which better solves the problems of uneven tension and easy wrinkles of the fabric in the cylinder. This process is carried out under normal temperature and pressure, the energy consumption is reduced, the chemical stability of the treatment liquid is good, and the damage to the fiber is small. The...

Embodiment 2

[0025] Example 2: OS open-width desizing

[0026] Process prescription (g / L) and conditions are as follows:

[0027]

[0028] TF-127K has excellent permeability, emulsification and dispersibility, and it can emulsify and decompose the slurry with liquid alkali to prevent the slurry from agglomerating. Sodium tripolyphosphate has significant chelating ability to metal ions such as calcium and magnesium, and is weakly alkaline and non-corrosive. This set of process combinations has obvious effects in preventing the size from back-staining and removing waterproof stains during desizing.

[0029] At this stage, the tension of the elastic frame of the desizing machine should be reduced, and the speed should be slowed down to reduce the damage to the elasticity of the fabric. After OS open width, the excess size on the cloth surface can be further removed.

[0030] Evaluation

[0031] The fabric in this case can remove the wrinkles of the cloth surface after being opened by t...

Abstract

The invention discloses a front section treatment method of polyester spandex face fabric. The method comprises the following steps of: gray batching, cold batch and open-width desizing; spandex in the polyester spandex face fabric adopts polyester type; the technical formula in the cold batch step comprises 100g / L liquid caustic soda, 2g / L hydrogen peroxide, 1g / L penetrating agent JFC, 3g / L chelating dispersant TF-510C and 5g / L deoil agent TF-104; and the technical formula in the open-width desizing step comprises 30g / L liquid caustic soda, 2g / L TF-127K and 2g / L sodium tripolyphosphate.

Description

technical field [0001] The invention relates to a fabric processing method, in particular to a front-end processing method of polyester spandex fabric. Background technique [0002] With the continuous improvement of living standards, people have more and more functional requirements for clothing fabrics. For traditional winter clothing that only has the function of keeping warm, its bloated, cumbersome and lack of novelty style has been difficult to satisfy consumers' consumption concepts. Moreover, with the frequent occurrence of warm winters, people are eager for more novel and dynamic winter clothing fabrics. Nowadays, elastic fabrics containing spandex are very popular in domestic and foreign markets. This kind of products has high elasticity and excellent rebound performance, soft hand feeling, comfortable to wear and can show the beauty of the body. In addition, it is easy to absorb sweat and will not generate static electricity. , so that it has always had a very st...
