Optical White Polyester Trilobal Shaped Filament is a special shaped filament. Its trilobal cross-section acts like tiny prisms to create unique pearl-like and silk-like luster. With high-purity optical white base, it delivers brilliant and clear color after dyeing. It also features high tenacity, stable dimension, weather resistance and good wash fastness. It is widely adopted in fashion, home textiles, embroidery, automotive interior and technical textile sectors.
1. High-End Fashion & Apparel Fabric Industry
This is its largest application field. The trilobal profile generates soft pearlescent shine similar to real silk. The optical white raw yarn can be used as off-white fabric directly or dyed and printed for bright, clean color performance. It is widely used for evening gowns, stage costumes, bridesmaid dresses, silk-like charmeuse, georgette, chiffon, lightweight woven and warp-knit fabrics for women’s wear, wedding dresses and tulle fabrics. Fabrics made from this filament have excellent drape and wrinkle resistance. It fits well with weaving, warp knitting and weft knitting processes.
2. Home Textile & Decorative Fabric Industry
It is popular for curtains, sheer curtain, upholstery fabric, cushion fabric, jacquard bedding, decorative tapestry and carpet face yarn. The shimmering luster upgrades the premium look of home textiles. It has good fiber cohesion and abrasion resistance, so its luster lasts well after long use. Many hotel and villa decoration orders select optical white trilobal filament for light and macaron color dyeing.
3. Computer Embroidery & Special Sewing Thread Industry
After twisting, it becomes high-luster embroidery thread, a favored raw material for embroidery. The optical white base ensures uniform color uptake and attractive shimmer. It resists breakage on high-speed embroidery machines. It is suitable for brand logo embroidery, garment embroidery, home textile embroidery, decorative labels and curtain lace embroidery. Compared with normal round embroidery thread, it offers better 3D effect and sparkling appearance.
4. Automotive Interior Textile Industry
It is applied to car headliner fabric, door decorative fabric, blended seat fabric and sunshade curtain. Polyester features heat resistance, low shrinkage and anti-aging performance. Optical white works well for light-color interior design. The trilobal structure improves fabric bulkiness and soft hand feel, meeting automotive standards for low odor and light fastness.
5. Technical Textile Industry
Filtration & cleanroom textiles: filter fabric and cleanroom wipe base material. Trilobal shape brings larger specific surface area and better adsorption capacity. Optical white makes dirt and impurities easy to spot.
Construction & geotextiles: auxiliary yarn for membrane structure, shading mesh and marking yarn, good UV resistance for outdoor service.
Non-contact isolation fabric for clean medical zones with controlled cleanliness.
6. Outdoor & Sportswear Fabric Industry
It is used for lightweight sport fabric, beach fabric and outdoor shading fabric. The fabric is breathable and quick-drying. After anti-UV finishing, it performs well for outdoor products with soft non-glare luster.
