Problems solved by technology

Since the cotton fabric needs to be taken out of the spray chamber before this process is carried out, this process will consume a lot of transfer time and affect the entire non-ironing finishing cycle
[0006] Furthermore, the free formaldehyde content of the cotton fabric obtained by the traditional non-ironing finishing method of the cotton fabric is relatively high, and increases with the prolongation of the storage time, and the surface of the treated fabric is yellowed, which cannot maintain the original color of the cotton fabric; The tearing and breaking strength are also greatly reduced, which affects the wearing life of cotton fabrics

Abstract

The invention provides a non-ironing finishing method for a pure cotton fabric. The method includes the working procedures of cleaning, drying, spraying, removing liquid, pre-drying, pressing, drying,standing, cleaning and re-drying. The adopted finishing liquid comprises the following components in mass concentration: 65-85g / L of a fiber protective agent, wherein the fiber protective agent comprises polyethylene, polyurethane and urea; 45-55g / L of a softener, wherein the softener components comprise a hydrophilic silicone softener and an amino silicone oil; 15-16.5 g / L of a catalyst; 1-1.2g / L of a penetrant; 150-165 g / L of resins; and the balance is water. The method has the advantages of improving the softness and smoothness of the fabric, enabling the fabric to have long-acting hand feeling and excellent wrinkle resistance effect.

Description

technical field [0001] The invention relates to the field of garment processing, in particular to a non-ironing finishing method for pure cotton fabrics. Background technique [0002] With the improvement of the quality of life, people have higher and higher requirements for clothing products. In addition to fashionable styles, they also require certain comfort. Cotton fabrics are highly flexible and comfortable to wear, but they have disadvantages such as poor elasticity, variability, and easy wrinkling, and cannot maintain a flat appearance during wearing. Therefore, the wrinkle resistance finishing of pure cotton fabrics is particularly important. [0003] The non-ironing finishing of pure cotton fabrics includes the process of spraying the finishing liquid, which needs to spray the finishing liquid evenly on the cotton fabrics. At present, the spraying process is mostly to directly place the cotton fabric in the spray chamber, and then rotate the cotton fabric through t...
