Problems solved by technology

In addition, due to the increasingly complex size components on polyester and nylon fabrics, the commonly used desizing methods such as alkali desizing, oxidant desizing, hot water desizing and mechanical desizing have their own defects and cannot achieve satisfactory desizing. Effect

Embodiment 1

[0013] Example 1: Cold pile fiber splitting

[0014] Process prescription (g / L) and conditions are as follows:

[0015]

[0016] In the above process, the chelating dispersant TF-133A can prevent equipment and fabrics from being stained, has the functions of scale inhibition and scale removal, and has good compatibility with desizing liquid. The degreasing agent TF-126A can remove the degreaser, and can quickly penetrate into the fabric. It has good emulsification and dispersibility, strong detergency, and has the functions of desizing, scouring and cleaning.

[0017] In view of some customers who have high requirements on the velvet feel in the hand feel, cold-pile fiber opening is required. After fiber opening by this method, the fabric has a softer cotton feel, which greatly improves the hand feel of the fabric and makes it more drape. In the process of cold stacking and rolling, the rolling and the speed of the machine should be synchronized to reduce the tension of th...

Embodiment 2

[0018] Example 2: OS open-width desizing

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

[0020]

[0021] 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, has weak alkalinity, and is non-corrosive. It has obvious effects in preventing slurry from sticking back and removing waterproof stains during desizing.

[0022] After OS open width, the excess size on the cloth surface can also be removed, and more importantly, the wrinkles on the cloth surface can be removed, which is conducive to maintaining the flatness of the cloth surface after dyeing.

Abstract

The invention discloses a front section treatment method of polyester and nylon interwoven fabric. The method comprises steps of cold batch fiber opening and open-width desizing, wherein the technical formula in the cold batch fiber opening step comprises 100 to 110g / L liquid caustic soda, 5 to 6g / L degreaser TF-126A, 10 to 12g / L hydrogen peroxide, 5 to 6g / L high effective scouring penetrant TF-125D, 2 to 3g / L chelating dispersant TF-133A, 2 to 3g / L cold batch agent and 3 to 4g / L desizing agent TF-127K; and the technical formula in the open-width desizing step comprises 3 to 4g / L desizing agent TF-127K, 2 to 3g / L hydrogen peroxide and 25 to 27g / L liquid caustic soda. The method effectively improves the production efficiency, shortens the production period and realizes purposes of energy conservation, emission reduction and cost reduction on the basis of guaranteeing the dyeing reproducibility, stability and one-time success rate.

Description

technical field [0001] The application relates to a pre-treatment method of fabrics, in particular to a pre-dyeing method of polyester-nylon interwoven fabrics. Background technique [0002] With the wide application of chemical fiber raw materials, the quality of the most popular nylon and polyester fabric products in the market has been greatly improved under the careful research and development and stable maintenance of major chemical fiber companies, and the product fineness is getting higher and higher. Brocade intertwined fabric products are especially favored by consumers. It integrates elasticity, softness, wrinkle resistance and drape, and is a fashion fabric product that consumers love very much. [0003] The technical difficulty of producing polyester-nylon interwoven fabrics mainly lies in the control of hand feeling, the two-color effect of polyester-nylon dyeing, and the color fastness of nylon yarn. Special attention is required to ensure the consistency and ...
