Application Techniques for CMC in Fabric Sizing

Carboxymethyl cellulose (CMC) is a versatile polymer that has found widespread application in various industries, including the textile industry. One of the key uses of CMC in textiles is as a sizing agent, which is used to improve the strength and handling properties of yarns and fabrics. In this article, we will explore the application techniques for using CMC in fabric sizing.

Fabric sizing is a crucial step in the textile manufacturing process, as it helps to improve the strength and appearance of the fabric. Sizing agents are applied to the yarn before weaving to provide lubrication and reduce friction during the weaving process. CMC is an ideal sizing agent due to its excellent film-forming properties and ability to provide good adhesion to the yarn.

There are several application techniques for using CMC in fabric sizing, depending on the type of fabric and the desired properties. One common method is to prepare a CMC solution by dissolving the polymer in water at a specific concentration. The yarn is then immersed in the CMC solution, ensuring that it is evenly coated with the sizing agent. The excess solution is then removed by squeezing or centrifuging the yarn.

Another popular technique is to apply CMC as a paste or gel directly onto the yarn. This method is particularly useful for fabrics that require a thicker sizing layer or for fabrics with special finishing requirements. The paste or gel is prepared by mixing CMC with water and other additives, such as lubricants or antistatic agents, to enhance the performance of the sizing agent.
