Abstract

The invention provides a burnt-out processing technology of a polar fleece fabric, and solves the problems of poor safety and environmental pollution caused by the existing alkali etching processing technology as well as the problems of high cost, single fabric design form, no overdyeing allowance after fabric processing and the like caused by the mechanism shear processing technology. The burnt-out processing technology provided by the invention is characterized in that the burnt-out printing is carried out on a polar fleece fabric blank by using a printing pulp material according to a designed flower pattern; and the processing technology comprises the following steps: burnt-out printing, drying, color fixing, water washing, soaping, water washing, dewatering, shaping and packaging, wherein the printing pulp material comprises the following components by mass percent: 45% to 55% of etching agents, 40% to 44% of disperse printing pastes, 2% to 8% of disperse dyes and the balance of water.

Description

technical field [0001] The invention relates to the technical field of functional knitted fabrics, in particular to a burn-out processing technology for polar fleece fabrics. Background technique [0002] At present, the burnt-out or etching process of polar fleece products can generally be carried out in two ways: alkali etching or mechanical shearing. The alkali etching method uses caustic soda and its concentration is high, which is in terms of operational safety. There are great hidden dangers and dangers, and the fabric cannot be registered after alkali etching, which lacks the flexibility of design; the method of mechanical shearing is generally expensive and has a single form, and there are also limitations in the flexibility of color registration. Contents of the invention [0003] Aiming at the defects and deficiencies in alkali etching and mechanical shearing, the present invention provides a burnt-out processing technology for polar fleece fabrics, which can...
