In the conversion chain of industrial fabrics from raw materials to finished products, the silk joining process is not simply "silk splicing", but the core link that determines product performance and production efficiency. Its existence is essentially to solve the inherent defects of single fibers themselves - single stranded fibers (such as PP and PET single fibers) often have low strength, are prone to breakage, and are prone to "drifting" due to uneven tension during weaving, making it difficult to meet the strict requirements of industrial fabrics for "high strength and high stability".

From a performance perspective, composite fibers are the "strength amplifiers" of industrial fabrics. By combining or twisting multiple monofilaments, the mechanical improvement of "1+1>2" can be achieved through the process of merging: the merging process allows parallel monofilaments to work together under force, avoiding single filament breakage and overall failure.

From a production perspective, the diameter of the single filament is small, the tension is difficult to control, the breakage rate during weaving is high, and the downtime is frequent. However, after merging, the filament bundle becomes thicker and the shape is stable, and the breakage rate can be reduced. In addition, the yarn can accurately control the yarn count and uniformity, ensuring that the industrial fabric texture is flat and the aperture is consistent.

It can be said that without the empowerment of the silk process, there would be no widespread application of high-performance industrial fabrics. It is not only the "bridge" connecting the preparation and weaving of silk materials, but also the "key password" for industrial fabrics to achieve breakthroughs in strength, function, and efficiency.
