Island polyester yarn is the dispersion of one polymer in another polymer, the dispersion phase in the fiber cross-section is "island" state, and the parent is equivalent to "sea", its "island" and "sea" components are continuous, dense and evenly distributed along the axis of the fiber. In the production process, it has the densification of conventional fibers, but the "sea" component is dissolved with a solvent, and a cluster of microfiber bundles can be obtained.
According to the general classification of fibers, after the separation of island fiber, the monofilament size is only 0.05D, which is a microfiber, which is impossible to achieve by conventional spinning.
Island polyester yarn have properties that are not possible with ordinary fibers
A. High coverage:
As the fiber density decreases, the diameter becomes thinner and the surface area per unit weight of the fiber increases. With the increase of surface area, the covering capacity of the fiber increases, and the hygroscopic property is greatly improved.
B. Feel soft and comfortable:
Because the fiber is ultrafine, the fiber is softer, and the fabric is made into a fabric, which can produce the core suction effect of the capillary, so that the fabric absorbs more water, and the water can be moved to the surface of the fabric, so that it can evaporate, and increase the comfort of wearing.
C. Fabric luster soft:
The smaller the diameter of the microfiber, the smaller the radius of curvature of the fiber, the greater the proportion of the scattered light reflected by the surface, so that the color of the fabric surface is softer.
Product type: High shrinkage polyester island yarn and composite polyester Island yarn.
