Optical White Polyester Trilobal Shaped Filament, with the core feature of polyester (PET) substrate+trilobal cross-section+optical white (high whiteness, high gloss/high extinction optional), is mainly used in four major fields: textile and clothing, home textile decoration, industrial textiles, and functional filling/coating materials, thanks to the flash/extinction effect, fluffiness, coverage, and whiteness stability brought by the cross-section, as well as the strength, weather resistance, and easy dyeing characteristics of polyester itself. The specific subdivision scenarios are as follows:
1、 Textile and clothing industry (most mainstream application)
The core advantage of a three leaf cross-section is the glossy/sparkling effect generated by light refraction, combined with the high whiteness of optical white, making it a distinctive yarn choice for clothing fabrics. Subdivision scenarios include:
Fashion women's clothing and dress fabrics
Fabric used for making evening gowns, bridesmaid gowns, and stage performance costumes, utilizing the optical refraction effect of the three leaf cross-section to give the fabric a soft pearl or sparkling texture. The optical white base can make subsequent dyeing purer, and can also be directly used as the original white fabric to enhance the delicacy and visual hierarchy of the clothing. It is commonly found in lightweight fabrics such as chiffon, chiffon, and polyester.
Knitted and woven decorative fabrics
Applied to the jacquard/inlay parts of women's knitted shirts, shirts, and dresses, or the warp and weft yarn embellishment of woven fabrics, the high whiteness of optical white combined with the fluffy feeling of the three leaf shape makes the fabric texture more three-dimensional, while improving the coverage of the fabric and reducing the problem of transparency, suitable for light luxury and commuting women's clothing fabrics.
Sports and outdoor functional clothing (auxiliary yarn)
As a blended component of functional fabrics, it is blended with nylon and spandex and used as a fabric or accessory for outdoor sun protection clothing and sports and leisure clothing. Polyester itself has UV resistance and wear resistance characteristics, combined with the fluffiness of the three leaf section, to enhance the breathability and visual texture of the fabric. Optical white also meets the demand for light color and high whiteness in outdoor clothing.
Socks and Knitwear Accessories
Used for wrapping yarn in mid to high end stockings and cotton socks, or knitted ribbed and lace accessories. The delicate luster of the trilobite filament gives the socks a more textured feel, and the optical white base is suitable for various dyes, while improving the elasticity and wear resistance of the yarn and extending the service life of the accessories.
2、 Home textile decoration field (high whiteness+gloss/extinction dual adaptation)
The optical white color is resistant to yellowing and has high whiteness, combined with the fluffy and covering properties of the three leaf shape, balancing aesthetics and practicality in home textile scenes. Its core applications include:
Decorative fabrics and curtains
The main yarn or decorative yarn used in the production of blackout curtains, gauze curtains, sofa covers, and pillows can be adjusted to have a glossy/semi matte cross section according to the process. The glossy version is used for light luxury curtains and decorative fabrics, presenting a soft luster; The semi matte version is suitable for minimalist home textiles, with high stability in optical white to avoid yellowing after long-term exposure to light. At the same time, the polyester's sun resistance and easy cleaning characteristics are suitable for long-term use of home textiles.
Bedding and filling materials
Jacquard fabric, bed flag, and pillowcase decorative edge for a four piece bedding set. The optical white base makes the bedding cleaner, and the fluffy three leaf shape enhances the softness of the fabric; It can also be used as a filling and wrapping yarn for down comforters and pillows, enhancing the wrapping and fluffiness of the filling material and optimizing the hand feel.
Carpets and tapestries (decorative)
Used for the surface layer yarn of handmade/woven tapestries and light luxury carpets, the light reflection effect of the three leaf cross-section makes the pattern more three-dimensional, and optical white is used as the base color or color scheme to enhance the visual brightness of tapestries and carpets. The wear-resistant and anti pollution properties of polyester material are suitable for ground decoration scenes.
3、 Industrial textile field (dual requirements of function and appearance)
Based on the physical properties of polyester and the structural advantages of its three leaf cross-section, it meets the needs of visual identification, filtration, protection, etc. in industrial scenarios. Optical white is suitable for high recognition and cleanliness requirements:
Textiles for filtration and cleaning
The base fabric yarn for producing industrial dust removal filter bags, air filtration materials, and clean room wiping cloths has a larger specific surface area with a three leaf cross-section, which enhances filtration and adsorption effects. The optical white color is easy to detect stains and impurities. The acid and alkali resistance and high temperature resistance of polyester are suitable for industrial filtration conditions, and can also be used for non direct contact decorative fabrics and isolation curtains in medical clean areas.
Geotechnical and architectural decorative textiles
Auxiliary decorative yarn for building membrane structures, identification yarn for geotextiles, optical white enhances outdoor scene recognition, tri leaf cross-section enhances yarn tear resistance, polyester weather resistance is suitable for long-term outdoor use, and can also be used for shading decorative mesh in parking lots and venues.
Automotive interior textiles
As a blended yarn for car seat covers, ceiling fabrics, and door decorative fabrics, optical white is suitable for the light colored design of car interiors. The three leaf shaped fluffiness enhances the softness of the interior, while the polyester's wear resistance, aging resistance, and easy cleaning characteristics meet the requirements of car interiors. At the same time, the glossiness can enhance the delicacy of the interior.
4、 Special filling and coating materials field
Using the fluffiness, resilience, and high whiteness of trilobite shaped filaments as filling or coating core materials, replacing traditional circular cross-section filaments to enhance performance:
Toys and Home Fillers
The filling fiber used for plush toys, pillows, and cushions has a three leaf cross-section with better fluffiness and resilience than circular filaments. The optical white color makes the appearance of plush toys cleaner, brighter, and less prone to yellowing. The anti caking and easy to maintain properties of polyester material improve the service life of the filling material.
Cable and pipe wrapping yarn
As the outer layer of braided yarn for wires, cables, and fire hoses, optical white is easy to identify cable specifications and detect damages. The three leaf cross-section enhances the tightness and wear resistance of the braided layer, and the insulation and temperature resistance characteristics of polyester are suitable for the functional requirements of cable wrapping.
Craftsmanship and Decorative Filling Materials
The filling fiber used for floral decoration and craft ornaments has a high gloss/extinction effect in optical white, which is suitable for visual design of floral art and crafts. The three leaf shaped filament has strong plasticity and can shape different shapes, while being resistant to moisture and not easily deformed.
