Improving Yarn Strength and Process Stability
In weaving and knitting operations, yarn breakage and abrasion are major causes of production loss. Sizing plays a critical role in protecting yarns during high-speed mechanical processing.
Polyacrylamide-based sizing agents are increasingly used in textile mills to improve yarn strength, surface smoothness, and processing stability.
Why PAM Is Used in Sizing Formulations
PAM forms a uniform and flexible polymer film on yarn surfaces, which:
- Reduces friction during weaving
- Improves tensile strength
- Enhances resistance to abrasion
Compared with starch-based sizing, PAM offers more consistent performance and easier control.
Operational Benefits for Textile Mills
- Fewer yarn breaks
- Higher loom efficiency
- Reduced machine downtime
- Improved fabric quality
Procurement perspective:
Stable sizing performance directly impacts production efficiency, not just chemical cost.
Selection Considerations
- Molecular weight suited to yarn type
- Film-forming ability
- Ease of desizing
- Compatibility with downstream dyeing
Conclusion
PAM-based sizing agents help textile plants improve productivity and fabric consistency. Proper selection ensures both performance and cost efficiency.
