1、 Definition
Superfine fiber is a kind of differentiated fiber developed rapidly in recent years. It is called a new generation of synthetic fiber. It is a high-quality and high-tech textile raw material. It is a kind of chemical fiber developing towards high technology and high simulation. Typical representative of new synthetic fiber.
2. Performance
Because the diameter of microfiber is small, its bending stiffness is very small, and the fiber feels very soft; The specific surface area of microfiber is large, so the coverage, bulkiness and warmth retention of microfiber fabric are significantly improved, and the specific surface area is large. The fiber has a higher frequency of contact with dust or oil, and the oil has more opportunities to penetrate through the cracks on the fiber surface, so it has a strong cleaning function; The ultra-high density fabric is made of ultra-fine fibers, and the gap between fibers is between the diameter of water droplets. And the diameter of water vapor droplets, so that the ultra-fine fabric has the effect of water and steam permeability; Microfibers have many micropores between microfibers to form capillary structure. If it is processed into a towel like fabric that can be wetted by water, it has high water absorption. Washed hair can absorb water quickly with this towel to make the hair dry quickly.
3、 Apply
Superfine fibers can be made into silk like, peach like, suede like, wool like and high-density products. The main application fields of microfiber include high-quality fashion fabrics, high-density fabrics, high-performance wet wipes, peach skin fabrics, human skin, high-quality lens cleaning paper, gas filter materials, etc. it can also be used in biomedicine, such as artificial blood vessels. Engineering field.
1. Silk like fabric
With the development of synthetic fiber spinning technology, the appearance and wearing performance of chemical fiber simulated silk fabrics are closer and closer to real silk, even to the point of fake and shoddy. The rayon fabric made of superfine fiber not only has the advantages of soft, comfortable, luxurious and elegant silk fabric, but also overcomes the shortcomings of silk fabric, such as easy wrinkling, sticky and poor fastness. Enough to meet people's desire for diversified and excellent clothing materials. requirement. From the development of ultra-fine rayon fabric, the fiber density is generally about 0.1-0.5dtex.
2. Ultra high density waterproof and breathable fabric
The ultra-high density fabric made of superfine fiber has high density, but light texture, good drapability, soft and plump feel and fine structure. Although it is not coated and waterproof, it is also highly waterproof and light. It is a textile product with high added value. This kind of fabric generally adopts polyester nylon stripped ultra-fine composite yarn, and the linear density of single silk is generally 0.1-0.2dtex.
3. Suede and artificial leather fabrics
Knitted fabrics, woven fabrics or non-woven fabrics made of superfine fibers can be sanded or roughened, then immersed in polyurethane solution, dyed and finished to make suede or artificial leather fabrics. Many properties of the fabric are as good as natural suede leather. It has light, thin, soft and smooth surface texture, waterproof, breathable, strong and deformation free.
4. High performance cleaning cloth
It is another representative product of microfiber products. The fabric has countless times of micropores than ordinary fabrics, and has higher specific surface area and micropores. Therefore, it has strong cleaning ability, rapid and complete decontamination, no fuzzing, and can be reused after washing. It is widely used in precision machinery, optical instruments, microelectronics, dust-free rooms and families. Microfiber will be widely used in various fields because of its excellent properties and a wide range of varieties.
