In recent years, with the improvement of textile technology and textile industry demand, sea-island composite microfiber has become one of the important textile materials.
Characteristic of Fibers
From the cross-section, sea-island composite microfiber is a component in a fine and dispersed state surrounded by another one, as if there are many islands in the sea. The islands are the main component, usually composed of PET, and the sea is the secondary component composed of alkali-soluble chips (usually called COPET). Our company is committed to the research of COPET. For more information, please refer to https://www.polyestermfg.com/alkali-soluble-polyester-chip/.
The “island” and “sea” components are continuous, dense, and uniformly distributed in the axial direction of the fiber. During the production process, it has the slenderness of conventional fibers. But when the “sea” component is dissolved with solvent, it can be obtained as a bundle of ultra-fine fiber. After the separation of sea island fibers, the single filament slenderness can reach 0.05D. According to the general classification, 0.05D is a superfine fiber. Conventional spinning can not get so fine fiber.
The fabric made from sea-island fiber does not lose hair, and will not pill or fade. The product is more wear-resistant, breathable, and has no stimulation to the skin. Since ultra-fine fiber is softer, its fabric can produce a capillary core suction effect. As a result, the fabric absorbs more water and can move this water to the surface, where the water evaporates. In this way, comfort and drapability are greatly improved. At the same time, the smaller the diameter of the microfiber, the smaller the radius of curvature of the fiber, and the greater the proportion of scattered light reflected on its surface so that the surface of the fabric is softer.
The performance of the imitation suede fabric developed by Sea Island Fiber is no less than that of natural suede, and many properties are even better than natural suede. Its fabric feels soft, has good drapability, light texture, and half of the real leather, and can be woven into different thicknesses and weights of the fabric. It can obtain a variety of surface effects with a variety of surface treatments. At the same time, the fabric drapes well, has a good breathable waterproof effect, high fabric strength, far better than the natural suede.
Through fabric design and processing, many special fabric styles, such as imitation suede and ultra-high-density fabrics, can be obtained by using the extremely fine fibrillation characteristics of sea island fibers. These fabrics can be widely used in footwear, home textiles, luggage, interior goods, and industrial fields, etc.
