Sea Island Fiber
Island Fiber
Sea-island fiber is a polymer dispersed in another polymer. The dispersed phase in the cross-section of the fiber is in an “island” state, while the matrix is equivalent to the “sea”. From the cross-section of the fiber, it is a component with tiny And the dispersed state is surrounded by another component, as if there are many islands in the sea. Its “island” and “sea” components are continuous, dense and evenly distributed in the axial direction of the fiber. During the production process, it has the fineness of conventional fibers, but by using a solvent to dissolve the “sea” component, bundled ultra-fine fiber bundles can be obtained.
According to the general classification of fibers, after the sea-island fiber is separated, the single fiber fineness is only 0.05D, which is an ultra-fine fiber. Conventional spinning is impossible, so it has characteristics that ordinary fibers cannot have.
a. High coverage:
As fiber denier decreases, the diameter becomes thinner and the surface area per unit weight of fiber increases. As the surface area increases, the covering ability of the fiber increases and the moisture absorption performance is greatly improved.
b. Soft to the touch and comfortable to wear:
Because the fibers are ultra-fine, the fibers are softer and can be made into fabrics, which can produce capillary wicking, allowing the fabric to absorb more moisture, and move the moisture to the surface of the fabric to evaporate, increasing the comfort of wearing it.
c. The fabric has soft luster:
The smaller the diameter of the ultrafine fiber, the larger the radius of curvature of the fiber, and the greater the proportion of scattered light reflected on its surface, making the tone of the fabric surface softer.
Through fabric design and processing, many special fabric styles can be obtained by taking advantage of the extreme fineness of island fiber, such as cashmere-like, suede-like, ultra-high-density fabrics, etc. This type of fabric can be widely used in clothing, clothing, luggage, indoor supplies and industrial fields.
Many properties of the suede-like fabric developed using sea-island fibers are no less than those of natural suede, and many properties are even better than those of natural suede. Its fabric feels soft, has good drape, and is light and thin in texture. It is half the thickness of real leather. It can be woven into fabrics of different thicknesses and weights; it can be subjected to various surface treatments to achieve various surface effects. The surface has a writing effect and a good three-dimensional effect; it has small shrinkage and deformation due to heat and humidity, has good breathability, waterproof and vapor permeability effects, and the fabric has high strength, which is much better than natural suede.
