Problems solved by technology

These printing pastes mainly have the following three disadvantages: one is that sulfuric acid is used as a burn-in agent, which is easy to burn hands during operation, and the residual acid in the printing is easy to absorb moisture in the air and make the printed patterns extend mutually, resulting in irregular pattern outlines. Clear; second, it is easy to bleed during burn-out printing, making the outline of the printed part unclear, or interpenetrating with the adjacent printing paste, destroying the effect of the pattern; third, the drying temperature in the production process is not easy to control, and the temperature is not enough When the carbonization effect is insufficient, the printed area will be white and opaque, which is difficult to wash off; if the drying temperature is too high, the printed area will be black and difficult to wash off

Abstract

The invention relates to cotton-polyester fabric burn-out printing gum and a preparation method thereof. The raw materials of the gum comprise the following components in parts by weight: 115-120 parts of acrylic acid, 8-10 parts of acrylamide, 17-19 parts of itaconic acid, 76-80 parts of sodium ethylenesulfonate, 220-240 parts of ammonia water, 3.0-3.5 parts of potassium persulfate, 1.8-2.5 parts of sodium bisulfite, 112-116 parts of corn starch and 480-510 parts of water. The preparation method comprises the following steps: performing solution polymerization, then adding corn starch in the copolymer to perform gelatinization and filtering to obtain the gum. The gum of the invention has good fluidity and stability, high permeability, good permeability, high definition of printing patterns and wide range of application temperature, is easy to wash with water and can obviously increase the quality of the printing product.

Description

technical field [0001] The invention relates to printing paste for burnt-out printing of polyester-cotton fabrics. Background technique [0002] Burnout printed fabric is one of the most popular textile products for consumers. Burn-out printing is a printing process in which the surface of a fabric composed of two or more fibers is mixed with a strong acidic substance and a printing paste, and then dried and washed to destroy a certain fiber component to form a pattern. Usually acid-resistant fibers (such as silk, nylon, polyester, etc.) and cellulose fibers (such as viscose fibers, cotton, etc. interwoven or blended) are woven into fabrics, and are printed with strong acidic substances. After drying, the cellulose is Strong acid hydrolysis and carbonization, after washing with water, a semi-transparent, concave-convex pattern can be obtained. [0003] The burnt-out printing on the market now mostly uses sulfuric acid as the burnt-out agent. The pastes for printing include...
