Product Description

Sea-island fiber (Island-in-the-sea fiber) as one of bicomponent fibers, also known as super-conjugate fiber or butterfly polyester yarn, is formed by a core component dispersed in another polymer in a longitudinally continuous way. Bicomponent (bico) fibers represent a special class of synthetic fibers / filaments that are made up of two different polymers. It is also called heterofil fiber. There are a number of arrangements that can be used, but the three most common are side-by-side, core-sheath and mixed polymer or islands in the sea effect. 

A bicomponent fiber is made from two or more polymers of different chemical (e.g. composition, additives) and/or physical (e.g. average molecular weight, crystallinity) nature, extruded from one spinneret to forma single fiber. This type of fiber is common in the carpet industry where one polymer has a different shrinkage temperature compared to the other.

Through spinneret design, it is possible to form fibers containing more than one polymeric component. In this arrangement, the polymers are not blended together but remain as discrete regions within the fiber.As for Sea-island, polymer material forms the core part, which is also called the island phase or dispersed phase. Another polymer is called sea component, sea phase, or continuous phase. Because original dispersed phase fiber presents as an island state in the fiber section, it is called sea-island fiber.

The island phase is formed by PET and PA, and the sea phase is formed by COPET.


Characteristic :
- Good dyeing with  continuously condensed and even structures. 
- Suede and leather made by sea-island fiber have good performance at: wearability, folding-resistance, hygroscopicity, breathability and easy clipping. Their color fastness is better than natural leather.

Applications :
 facial mask, ultra-fine PU leather fabric, high - end fashion leather, shoe leather, bag leather, leather for automobile, etc
