Sizing:
What is Sizing Process?
The sizing process in textile is a preparatory treatment
applied to warp yarns before weaving. This process involves applying a
protective coating, known as sizing, to the yarns to improve their strength,
flexibility, and smoothness, and to prevent them from breaking during weaving.
The sizing process typically involves the following steps:
Preparation of sizing mixture: The sizing blend is generally comprised of a mix of natural or synthetic polymers, lubricants, and other chemicals. The blend is prepared in large tanks or vats and heated to a specific temperature.
Application of sizing: The warp yarns are then passed through the sizing blend, which coats each yarn with a thin layer of sizing. The yarns are then squeezed to remove excess sizing and dried.
Sizing drying: The drying process can occur on a cylinder, using hot air or infrared radiation. The temperature of the drying process must be controlled to avoid degradation of the yarn.
Sizing removal: After the yarns are woven, the sizing is generally removed by washing or steaming. This process helps to restore the natural properties of the yarn and improves the quality of the finished product.
