the production process of artificial grass fibers

Shaping mainly includes heat setting and cooling setting: the stretched fibers are heated again (100-130℃) to eliminate internal stress, then cooled to room temperature to ensure that the fibers do not deform during use. Texturing is to make the surface of the fibers have irregular convex and concave structures or curved shapes, which can enhance the friction between the fibers and improve the simulation of natural grass. Common texturing methods include mechanical texturing and chemical texturing, and the key is to control the texture density and depth to avoid excessive texturing affecting the fiber strength.

Finally, the fibers are cut and inspected. The shaped fibers are cut into fixed lengths (usually 20-100mm, according to the use scenario) using a cutting machine, and the cutting accuracy is controlled to ensure that the length error is within ±1mm. The inspection link includes appearance inspection (no discoloration, no breakage, uniform diameter), performance testing (tensile strength, elongation at break, anti-aging performance, wear resistance) and quality sampling inspection. Unqualified products are sorted out and recycled to ensure the qualified rate of finished products. The key technical point of inspection is to establish strict testing standards and sampling methods to avoid unqualified products entering the market.

In summary, the production process of artificial grass fibers is a systematic project involving raw material selection, melt extrusion, stretching, shaping and texturing, cutting and inspection. Each step has strict technical requirements, especially the temperature control in extrusion and stretching, the proportion of raw materials, the stretching ratio and the texturing effect, which directly determine the quality and performance of the final fibers. With the continuous development of technology, the production process of artificial grass fibers is constantly optimized, and the research on new raw materials and new processes will further improve the simulation, durability and environmental friendliness of the fibers, promoting the sustainable development of the artificial grass industry.
