A kind of production technology of reactive printing paste

Abstract

The invention relates to a production process of reactive printing paste. The production process comprises the steps of preparing carboxymethyl starch, preparing a mixture of carboxymethyl starch and nano silicon dioxide, preparing protein slurry, and mixing the ingredients. The paste mainly comprises carboxymethyl starch, sodium alginate, hydroxypropyl guar gum, nano silicon dioxide and protein slurry as assistants, and all performance of the paste can meet the active printing requirements.

Description

technical field [0001] The invention relates to a production process of active printing paste. Background technique [0002] In reactive dye printing, pastes are generally used as thickeners to adjust the rheological properties of colorants. Sodium alginate has always been the first choice for reactive dye printing pastes because of its advantages of not reacting with reactive dyes, high color yield, complete color spectrum, easy to wash off from fabrics, and soft fabrics. But it is more expensive, and the printing cost is relatively high, so it has become a top priority to find a low-cost paste that can print fine patterns. [0003] Starch is a renewable resource, which is abundant in reserves and easy to obtain. However, there are active hydroxyl groups on its molecules, which are easy to react with dyes, so the application of reactive dye printing pastes is limited. [0004] It was found by the inspection institute that the Chinese invention patent application CN1029659...
