Sizing Machine

In the sizing process, the warp sheet is immersed in an adhesive and binder paste, squeezed to remove excess adhesive, dried, and then wound onto the weaver’s beam. This process enhances warp yarn strength and reduces hairiness, but the moderate tension applied can cause yarn elongation, a drawback of sizing. The choice of sizing agents is crucial, as improper sizing can lead to weaving difficulties, while excessive sizing can create additional challenges. Optimal process and quality control ensure better yarn performance, making precise application and selection of sizing ingredients essential for efficient weaving.

Typical problems include

• Lower productivity – machines operate at less than rated capacity
• Excessive steam consumption
• Over or undersizing resulting in weaving defects
• Comb breakage caused by yarn breaks after passing through the drying cylinders, often due to improper temperature profiles.
• Yarn breakage near the sow box due to starch temperature inconsistencies
