Island composite fiber is mainly used to produce suede, including warp and weft weaving.
When one kind of polymer is dispersed in another kind of polymer, the dispersed phase in the cross section of the fiber is in the state of "island", while the matrix is equivalent to "sea". From the cross section of the fiber, one kind of component is surrounded by another in the state of fine dispersion, as if there were many islands in the sea. When the "sea" component is dissolved by solvent, a cluster of microfibers can be obtained.
The characteristics for sea island:
Core silk and leather silk shrinkage difference, leather silk protruding, velvet feeling more plump, suede series feel more soft, comfortable
Sea-island superfine fiber is a polymer dispersed into another polymer, dispersed in the fiber cross section is "island" shaped, whereas the parent is equivalent to the "sea". Fabric through the de-weighting finishing to dissolve the island component, the single fiber is as high as 0.03DPF(denier per filament) of superfine fiber.
The fiber can spin adding color master batch, fabric made with this fiber has unique style and superior comfort, good breathable and waterproof, strong decontamination ability. It is mainly used for faux suede, synthetic leather, moss velvet fabric, etc.

a,High coverage:with the lower DPF of the filament,diameter gets thinner,surface area per unit weight of the filament increases,With the increase in surface area,filament coverage is increased,hygroscopic property has been greatly improved.
b,Soft,comfortable: Because of fine filament, it gets softer, the finished fabric is able to have capillary effect,which absorbs more water. Moreover, it can transfer the water to the surface and be helpful to evaporation effect, assuring the wearing is much more comfortable.
c,Soft Luster: the diameter of filament is smaller,the radius of curvature of the filament is smaller also,scattering light gets mcuh more,and color tune is softer ,making fabric have soft luster.
Such as imitation Cashmere ,imitation Suede,high-density fabric and so on.This fabric can be widely applied in high-quality apparel ,casual wear,luggage,household and some industrial using.
