Are There Islands In The Island Fiber?

Island fiber, also known as super conjugated fiber and matrix precursor fiber, is formed by a core component (also called "island" or dispersed phase) composed of a polymer material, which is dispersed vertically and continuously in the sea component (also known as "sea" or continuous phase) of another polymer material.

Because the dispersed phase fibrils are islands in the fiber cross section, they are called Island fibers.

Island fiber was first developed in the early 1970s, and was originally used for production.

。

In 1970, the Japanese Dongli company first introduced the artificial deer skin fabric "ECSAINA", which was made of dissolved superfine fiber (sea island superfine fiber), marking the beginning of the industrial production of sea island composite microfiber.

In 1972, Japan's China textile company also successfully developed dissolving polyester - brocade.

The trade name is "BELIMA".

In recent years, Japan, Korea, China, Taiwan, the United States and Italy have all developed and produced.

In Japan, the United States and Europe, the island fiber has been industrialized and the technology is relatively perfect. South Korea and Taiwan also have some representative products.

China began to study Island complex in early 1970s.

However, only substantive progress was made in 90s. During the "75" period, it was included in the national science and technology development plan.

Island fiber has two production methods: composite spinning method and blended spinning method. The composite island fiber and blended island fiber are obtained respectively. The island components are generally PET and PA, and sea components are mostly COPET, PVA, PE and PS.

The production methods of island fiber are as follows:

According to the difference between the soluble components in the fibers as islands or marine facies, the composite island fibers are also divided into island type island fibers and non Island Island fibers.

After the island was dissolved, the "island" of the island shaped island was obtained and hollow fibers were obtained.

Island fiber has excellent properties that ordinary fibers can not achieve. Its main characteristics are as follows:

The fabric feels soft and smooth, and has obvious advantages in comfort. It can obtain high density, hygroscopicity, water repellency and unique aesthetics.

Stylish fabrics.

At the same time, multi-layer structure can be formed on the surface of the fabric, so that the reflective spot of the fabric is small, luster, color and luster are soft, and the appearance is full, fine and clean.

The interspace between the fibers is dense and dense, which can make the fabric obtain better water absorption and oil absorption by using its capillary action.

In addition, the gap between the fibers can be properly changed, and it can be woven into the island high density fabric with a gap of only 0.2 mu m~10 m.

The microporous structure of fabric allows more static air in the fabric, thus obtaining better heat insulation and warmth retention function.

The bending stiffness of the fiber is small, and the fabric is easy to get elegant and natural effect. The core layer is high shrinkage silk, which gives the fabric excellent drape and visual comfort.

The fiber has a large surface area and lots of space, so that the fabric has strong dust absorption, decontamination and filtration. The fiber is thin and soft, which can protect the cleaned items from being hurt, and is a high-performance cleaning product.

In addition, the island fiber fabric not only has the advantages of ironing, good dimensional stability and small shrinkage, but also has the advantages of good natural fiber drape, moisture absorption and moisture permeability.

Application of island fiber

1, fashion fabrics

Because the number of monofilament of the superfine fiber is more than that of the ordinary filament, the surface area of the fiber is large and the permeability of the fabric is increased. The nonwoven fabric is used as the base cloth after the non woven fabric. After the polishing and sand washing, the super natural fabric is made. Because its permeability and softness are superior to that of the natural textile, the fabric is ranked in the high grade.

Field.

2, artificial leather

The PU leather with fine fiber as the base has not only the micro structure similar to the natural leather, good moisture permeability and dimensional stability, fastness is superior to natural leather, but also avoids the defects of natural products due to the difference of the species, size and location of animals, resulting in the unevenness and low utilization rate.

In addition, PU leather has overcome the natural leather due to its own protein fiber easily damp, moldy and smelly, and is well received by consumers.

3, high-performance wipes

Microfiber, due to its small size, large surface area, good softness and strong water absorption and absorption, will not only damage the substrate without cleaning the thin oil film, but also wipe it clean, leaving no residue. It can be used as a high-performance cloth, such as top grade mirror cloth.
