Description

A kind of pure cotton fabric and its softening, antibacterial and anti-mildew technology

Technical field

The invention relates to the technical field of pure cotton embryonic fabric processing, and specifically relates to a pure cotton embryonic fabric and its softening, antibacterial and mildew-proofing process.

Background technique

Pure cotton gray fabrics formed through weaving processes such as printing, dyeing, and bleaching are used to form a series of products such as towels, bath towels, and pillow covers through post-processing processes such as slitting, cutting, and hemming. In the production process of the existing pure cotton gray cloth in the towel factory, due to the natural fiber characteristics of pure cotton, it is not easy to change its properties. It is necessary to add a variety of single-function fabric finishing agents to achieve softness, antibacterial, anti-mildew and other functions for pure cotton gray fabrics through dipping or padding. Since different functional types of fabric finishing agents need to be added in order for pure cotton gray fabrics to achieve functional effects such as softening, antibacterial, and anti-mildew, the current production process is very complex, and fabric finishing agents with different functions are not compatible with each other during the production process. There is a huge difference, so the relevant process operation settings are cumbersome, and most of them require the use of chemical additives containing heavy metal ions to complete the relevant processes, resulting in great process wastewater pollution.

Due to the single efficacy and poor compatibility of various fabric finishing agents in the existing pure cotton gray fabric production process, the produced pure cotton gray fabrics have unstable functions such as softening, antibacterial, and anti-mildew, are short-lived, have poor durability, and have serious problems. Process wastewater containing heavy metal ions can easily cause environmental pollution.

In view of this, the present invention is proposed.
