CMC In The Textile Printing And Dyeing Industry And The Detail Specifications And Requirements

- Dec 08, 2017 -

YUYU ® sodium carboxymethyl cellulose CMC(CAS 9004324) can be widely used in the textile industry as sizing agent, which can be used in chemical fiber, chemical fiber or blended fabric, warp yarn. CMC aqueous solution is transparent, uniform, good stability. Dyeing and printing grade sodium carboxymethylcellulose CMC solution has rich viscosity and film-forming property. The surface of the warp yarn can form a smooth, wear-resistant and pliable film that can withstand the absolute strength of the loom and provide favorable conditions for high-speed production. Yarns treated with a CMC aqueous solution are easy to dry, shiny and soft to the touch. Printing paste CMC as a thickener, emulsifier for printing paste. Especially suitable for silk printing paste. In man-made fiber fabrics, such as cellulose acetate printing pastes, should contain high boiling point solvents, dyes, water and appropriate thickeners.

Normally in the printing and dyeing industry CMC sodium carboxymethyl cellulose is demanded for good physical and application performance requirements. Performance generally requires degree of substitution of at least 1.0 or more, 1.3,1.5 or 1.8 degrees of substitution are required for higher requirements. In Japan, DS 2.0 or more are usually available because of its excellent workmanship, advanced equipment and advanced technology degrees, we can imagine how good the application effect, but for consumers, the high cost is a factor to be considered, because it is not an order of magnitude price consideration. In addition to the gel particles to be few, the laboratory requires technical conditions for system testing, generally requires at least not more than 4 gel per square centimeter, which can be regarded as qualified. Secondly, the free fibers in the solution should be almost invisible, so that it will not appear in the actual use of the phenomenon of congestion.

Here only by the performance of CMC printing itself to determine how to better apply the printing and dyeing industry, printing and dyeing applications as a good thickener and emulsifier, corresponding to the actual printing effect, such as to provide good permeability, increase Color paste stability and adhesion, increase the softness of the texture.
