Yarn Quality Requirements for Industrial Filter Cloth Weaving

In the production of industrial filter cloth, the weaving process is the key stage that determines product quality. High-quality filter cloth relies not only on advanced equipment and technology but also on the quality of the yarn itself. To achieve a stable structure, high strength, and excellent filtration performance, it is essential to strictly control three key factors: yarn strength, yarn faults, and yarn tension.

Requirements for Yarn Strength

Adequate yarn strength is a necessary condition for smooth weaving production, especially in high-speed, high-tension shuttleless weaving. Insufficient yarn strength can lead to frequent warp and weft breakages, which are the main causes of weaving defects such as broken ends and bars.

Yarn strength refers not only to the inherent strength of the raw yarn but also to the strength of warp sizing. Следовательно, it is crucial to ensure that the warp sizing has sufficient reinforcement and uniform strength distribution to maintain consistent weaving performance.

Requirements for Yarn Faults

Irregular yarn levelness, nubs, neps, and impurities can cause surface defects on the filter cloth. Nubs and impurities may lead to warp adhesion, resulting in fabric flaws and affecting filtration uniformity. High-quality industrial filter cloths should be made from high-grade yarns with uniform thickness and no visible defects, which helps reduce loom downtime and ensures a dense structure and smooth surface.

Requirements for Yarn Tension

Uniform warp tension is another critical factor affecting weaving efficiency and fabric appearance. Uneven tension can cause warp breakages, streaks, and other fabric defects, lowering the final product grade. Следовательно, tension must be carefully controlled throughout warping, sizing, and weaving to ensure consistent stress on each yarn sheet, resulting in tightly structured and evenly thick filter cloth.

Conclusion

Yarn quality is the foundation of filter cloth performance. Only by strictly controlling yarn strength, minimizing yarn faults, and ensuring uniform tension can manufacturers produce high-quality industrial filter cloth.
