What are the main components of sizing agents for Shaanxi cotton-polyester grey cloth?

The main components of the sizing agent for Shaanxi polyester-cotton grey cloth include polyester fibers, cotton fibers, as well as various additives and functional components. Specifically:

Polyester fibers and cotton fibers: These are the basic components of the sizing for polyester-cotton grey cloth. Generally, polyester fibers account for 50-60%, and cotton fibers for 40-50%. Through sizing treatment, these fibers can enhance the fabric's abrasion resistance, crease resistance, and dimensional stability, while also improving its drape and hand feel.

Additives: To improve the functionality of the slurry, a variety of additives need to be added, including:

Thickener: Increases the viscosity of the slurry, enabling it to better coat the fiber surface and enhance the adhesion between fibers.

Softener: Makes the fabric more soft after sizing and reduces the roughness of the hand feel.

Antistatic agent: Reduces the accumulation of static electricity on the fabric surface, preventing dust adhesion and malfunctions caused by static discharge.

Antimicrobial agent: Inhibits bacterial growth and enhances the hygiene performance of fabrics.

Ultraviolet absorbers: Prevent fabrics from discoloring and aging under sunlight.

Functional components: To endow the sizing agent for polyester-cotton fabrics with more functionalities, some functional components such as water repellents, flame retardants, and UV absorbers can be added. These components can enhance the protective performance of the fabric and prolong its service life.

Solvent: It is used to dissolve and dilute the slurry, enabling it to better cover the surface of the fibers. Commonly used solvents include water and organic solvents such as alcohol and ether.
