Top 10 sizing agent Manufacturers in China 2026

Introduction to Sizing Agent

Sizing agents are substances used in various industries, especially in the textile and paper industries. In the textile field, sizing agents are applied to yarns to improve their strength, abrasion resistance, and smoothness, which helps in the weaving process. They form a protective film on the yarn surface, reducing hairiness and preventing breakage during weaving. In the paper industry, sizing agents are used to control the absorption of liquids, such as ink, by the paper. They can enhance the paper's water - resistance, printability, and surface strength.
