Semi Dull Polyester Trilobal Shaped Filament

      Semi Dull Polyester Trilobal Shaped Filament is a sub category of polyester fiber (polyester), made from polyethylene terephthalate (PET, polymerized from purified terephthalic acid PTA and ethylene glycol EG) as raw material. The fiber cross-section is controlled to form a three lobed shape through a "trilobite spinneret", and an appropriate amount of titanium dioxide matting agent is added to the spinning process. The trilobite cross-section creates natural grooves and gaps on the fiber surface, increasing fiber fluffiness, providing a soft and dry touch, and reducing the feeling of stuffiness and heat near the body; On the other hand, it accelerates the diffusion and evaporation of moisture, enhances moisture absorption and sweat wicking properties, and is suitable for close fitting or sports scenes. The combination of semi extinction characteristics and the "diffuse reflection" effect of irregular cross-sections results in a natural and non glaring luster of the fabric, weakening the wax like texture of ordinary light fibers and making it more high-end and delicate, suitable for the texture needs of clothing and home textiles.
