Profiled Fiber synthetic fiber

A non-circular cross-section synthetic fiber spun from a profiled spinneret. Synthetic fibers have a variety of unique properties. But after making the fabric after some of the performance is often not as natural fiber. In order to make the synthetic fiber with the advantages of wool or silk, often imitate the characteristics of natural fiber structure, without compromising the basic properties of the fiber under the premise of the spinning fluid through a specific nozzle hole forming, made of the corresponding cross-section of the synthesis Fiber, which is a physical modification method. Viscose or acrylic fiber spinning fiber cross section is not circular, and was serrated

Or dumbbell-shaped, but not alien fiber.

The sections of the profiled fibers are triangular, pentagonal, trilobal, leafy, dumbbell-shaped, elliptical, l-shaped, lotus-shaped and round and hollow. Different types of profiled fibers have different properties. Triangular fibers have a flash, can make beautiful flash wool and coat. Pentagonal fiber has a significant sense of wool, with a good anti-pilling, can be made of senior silver gun coat it. Five leaf-shaped fiber is like silk, fabric soft and smooth and no wax sense, can be made into a sense of silk and very cool fiber characteristics of the material. L-shaped fiber has a good hygroscopicity; hollow fiber light weight, warm, feel good, can be made of cotton or blankets and so on.

  Shaped fiber cross section and nozzle hole shape

The profiled fibers are generally made of profiled spray holes. Choose different shapes of the nozzle hole can be made of different sections of the shaped fiber. It is also possible to use a technique such as melt-to-tack, composite wire separation, post-treatment deformation, center blow molding, composite filament or the like, or to use profiled fibers such as fiber surface deformation.

Shaped fiber can be woven into monofilament, multifilament, short fiber and fiber bundles, stretch yarn and so on. Fabrics made of profiled fibers have a flash and soft, smooth, bulky feel, close to wool or silk. Shaped fiber suitable for making a variety of new fabrics, artificial fur, synthetic leather base fabric, artificial suede, etc., in the medical, waste treatment and cigarette filter, etc. have also been applied.

With the cotton prices hit record high, as the textile industry in the important varieties and an important alternative to cotton, polyester fiber demand gradually increased. According to Wind information, as of last Friday, polyester staple fiber prices rose to 14,900 yuan / ton, compared with the beginning of this year rose 14.2%, other polyester products, including polyester partial yarn (POY), polyester full stretch silk (FDY ) And polyester stretch yarn (DTY) this year's price increases are also in the 7% -10%. At present, the polyester industry is in the process of rising economy, the profitability of production enterprises to improve rapidly. Among the many listed companies in the polyester, we are most optimistic about the upstream raw material PTA production capacity of the integrated polyester production enterprises.

Downstream demand growth to promote the development of the industry

Polyester is an important variety in synthetic fibers. In 2003, in the global fiber consumption structure, the proportion of polyester reached 38.3%, the first time beyond the cotton to become the largest fiber varieties. At present, polyester as the largest textile fiber varieties, has more than cotton, wool, silk, linen and other natural fibers and the sum of other chemical fiber. Therefore, the growth of the demand for the textile industry is the main driving force for the development of polyester industry.
