What are the different types of sizing process?
The sizing process is a critical step in textile manufacturing that involves applying a temporary coating or film on the surface of the fabric to improve its weaving, processing, and handling properties. There are different types of sizing processes used in textile manufacturing, including:
Starch Sizing: In this process, starch is applied to the fabric to provide strength and stiffness to the fibers, making them easier to handle during weaving.
Synthetic Sizing: This process involves using synthetic polymers, such as polyvinyl alcohol, to improve the fabric’s strength, smoothness, and wrinkle resistance.
Protein Sizing: In this process, proteins, such as casein or soybean protein, are applied to the fabric to improve its strength and stability.
Wax Sizing: In this process, wax is applied to the fabric to improve its water repellency and to prevent the fibers from sticking to each other.
Mineral Sizing: This process involves using minerals, such as kaolin or talc, to improve the fabric’s stiffness, smoothness, and strength.
The selection of the sizing process depends on the fabric type, the desired properties, and the intended end-use of the fabric. Each sizing process has its advantages and limitations, and the selection of the right sizing process can significantly impact the quality and performance of the finished fabric.
