AI Technical Summary

Technical Problem

The textile industry faces challenges in desizing and shrinking fabrics in an environmentally friendly and cost-effective manner without using excessive amounts of solvents, water, and chemicals, while ensuring controlled and reliable processing at high speeds.

Method used

A method and apparatus that involves wetting the fabric with a first pool of liquid, passing it through a heatable roller chamber, soaking it in a main pool of liquid, and treating it with ozone gas to achieve desizing and shrinking, optimizing conditions such as temperature, pH, and liquid flow to enhance efficiency and throughput.

Benefits of technology

The method and apparatus enable high-speed, controlled desizing and shrinking with reduced water and chemical use, achieving significant fabric shrinkage and desizing while maintaining fabric quality and reducing environmental impact.

Abstract

An apparatus for desizing and / or shrinking a textile fabric, the textile fabric having a length and a width, the method including moving, lengthwise, the fabric, and wetting the fabric within a first pool of liquid, the first pool of liquid including water; passing the fabric through a chamber, and in the chamber contacting the fabric with at least one heatable roller heated at a treatment temperature; soaking the fabric with a main pool of liquid, the main pool of liquid including water; and treating the fabric with ozone. The apparatus includes a first module for wetting the fabric, a second module with a heatable roller for heating the fabric, a third module for soaking the fabric, and fourth module for treating the fabric with ozone. The second module may optionally be integrated with the first module.
