Abstract
A method for making a burnout fabric includes: (1) pre-treating a greige fabric; (2) processing the pre-treated greige fabric with a burnout paste containing sulfuric acid, synthetic gum tragacanth, and sodium alginate; and (3) post-treating the greige fabric after the burnout treatment to obtain a burnout fabric. The method according to the present invention is simple in process, low in cost, and easy to implement, and the burnout fabric obtained thereby has an attractive and clear pattern, featuring a three-dimensional effect and a high quality.
Claims6
A method for making a burnout fabric, comprising the steps of:
- (1) pretreating a greige fabric, which comprises:
- stitching, washing with water, oxygen bleaching, and stoving the greige fabric for the first time;
- (2) performing burnout treatment on the pretreated greige fabric by means of a burnout paste containing sulfuric acid, synthetic gum tragacanth, and sodium alginate;
- and
- (3) performing post-treatment on the greige fabric that has experienced the burnout treatment, to obtain a burnout fabric, the post-treatment including:
- stoving for the second time, steaming, washing, and drying;
- wherein in step (1), the greige fabric is obtained by subjecting a core-spun yarn to spooling, heat setting twisting, warping, quilling, sizing, and weaving process, sequentially, and
- wherein the core-spun yarn comprises a hydrophobic polyester filament as a yarn core wrapped with a hydrophilic cotton fiber;
- a twist factor of the core-spun yarn ranges from 300 to 450;
- a cotton coverage of the core-spun yarn ranges from 43% to 48%.
