What characteristics does the Polyester Trilobal Shaped Filament possess through the triangular spinneret spinning process?

1、Traditional ordinary polyester filaments are produced with circular spinnerets, forming smooth round cross-sections, which lead to single structural performance and limited fabric presentation effects. Different from conventional spinning methods, Polyester Trilobal Shaped Filament is manufactured with professional triangular spinnerets. The molten polyester raw materials pass through special triangular holes for extrusion and molding, forming a stable trilobal cross-section structure after cooling and stretching. This unique molding method changes the single circular structure of common polyester fibers, laying a foundation for the fiber’s special physical properties. The improved spinning process stabilizes the structural uniformity of each filament, ensuring consistent fiber shape and specification in batch production, which creates favorable conditions for subsequent textile weaving and finishing processing.
2、The triangular spinneret spinning process endows Polyester Trilobal Shaped Filament with unique optical and tactile characteristics. The trilobal section forms multiple refraction surfaces on the fiber surface. When light irradiates the fabric woven from this filament, multi-angle light refraction occurs, presenting soft and layered luster effect. This feature makes up for the dull visual state of ordinary polyester fabrics and enriches the surface texture of textile products. Meanwhile, the special cross-section structure changes the contact mode between fibers and human skin. The gap formed by the trilobal structure increases air permeability inside the fabric, reduces skin adhesion, and improves the dry and comfortable wearing experience of polyester textiles in daily use.
3、The special spinning structure brings outstanding structural stability and weaving adaptability to Polyester Trilobal Shaped Filament. The trilobal stereo structure enhances the cohesion between fibers during yarn twisting and weaving. Fibers are not easy to loosen and slip, which improves the structural compactness of yarns and fabrics. In the post-processing process such as dyeing and finishing, the special fiber structure can absorb dyes more evenly, promoting uniform color attachment and reducing color difference on the fabric surface. This shaped polyester filament can adapt to the production of various textiles including clothing fabrics, decorative cloth and home textile materials, matching different weaving processes and production modes of modern textile workshops.
