Performance
The surface structure of PTT fiber is in the shape of smooth strips, and the light reflection and refraction are strong, and the fiber luster is strong; there are gaps on the surface, and it has certain moisture conductivity, air permeability and warmth retention; it can be made into fibers of various cross-sectional shapes Products can also be directly processed into colored PTT fibers during the manufacturing process, which is convenient for selection.
The "Z" helical structure of PTT fiber makes it superior to other fibers in high elasticity and good rebound performance. Due to the lower glass transition temperature of PTT fiber, it can be dyed at normal pressure. Due to the special structure of PTT, the dye is more likely to enter the fiber, so the dyeing performance is better than that of PET fiber. PTT fiber combines the advantages of various fibers, such as the stain resistance of polyester, the softness of nylon, and the bulkiness of acrylic. Compared with elastic fiber spandex, it is easier to process and is very suitable for textile and garment fabrics.
PTT fiber also has good thermal stability, anti-wrinkle, antistatic, anti-ultraviolet and so on. The performance comparison between PTT fiber and other fibers is shown in Table 2.
Application:
The excellent performance of PTT fiber makes it very suitable for clothing fabrics. Its good dyeing and printing adaptability can be used to produce a variety of dyed fabrics, stain resistance can make clothes easier to care and wash, its soft feel and elasticity, low water absorption and good drape can Improve the wearing comfort of clothing. Blending PTT fiber with other fibers can obtain products with better performance. For example, PTT fiber is interwoven with cellulose fibers such as cotton, viscose, tencel, and hemp, which has good hand feeling and crease resistance, and can be used for knitted underwear, woven fabrics, etc.
PTT and mulberry silk are interwoven for memory fabrics, which not only makes up for the difficult-to-manage defects of mulberry silk products, but also makes its performance far exceed that of pure fiber memory fabrics. The use of PTT fiber in memory fabrics can make it lighter, softer, skin-friendly, sweat-absorbent and breathable.
PTT has excellent anti-fouling properties and good antistatic properties, and can be used in the production of carpets. At the same time, PTT fiber is also a good material that can be used to prepare nonwovens, and can also be used in other fields, such as bedding, decorations, car mats, webbing, etc. At present, the unique properties and advantages of PTT fiber make it develop rapidly and have a very good development prospect. With the continuous deepening of research on PTT fiber processing and application, its application fields will be more diversified.
