Common Sizing Defects & Solutions

Identify defects like hairiness, shedding and uneven pick-up.

By Welchem Technical Support Team · March 2025

Sizing defects can significantly iampct loom efficiency, fabric quality, and overall production costs. Identifying root causes and applying the correct solutions is essential for stable textile operations.

Hairiness & Fuzz Formation

Excessive yarn hairiness often results from inadequate film formation or incorrect viscosity. Optimizing polymer selection and solids content helps reduce fuzz.

Shedding & Size Flaking

Shedding occurs when the size film lacks flexibility. Using plasticized or acrylic-modified sizing agents improves adhesion and reduces flaking.

“Most sizing defects are process-related and can be eliminated with correct formulation and control.”

Uneven Pick-up

Uneven size pick-up is caused by poor penetration, improper squeeze pressure, or unstable viscosity. Regular monitoring ensures uniform application.

Conclusion

With proper troubleshooting and advanced chemical solutions, common sizing defects can be minimized, leading to smoother weaving and higher productivity.
