Superfine fiber, also known as superfine denier. (Denier is the unit of fiber denier. One gram of 9000 meters long silk is denier, and the unit of silk denier is 1.1 denier). Because it is thinner than traditional fibers, it is more fluffy and soft to the touch than ordinary fibers, and it can overcome the shortcomings of natural fibers such as creases and rayon impermeable. In addition, it also has many irreplaceable excellent characteristics such as warmth, no mold, no insects, light weight, and waterproof. The types of ultrafine fibers include ultrafine denier viscose yarn, ultrafine denier nylon yarn, ultrafine denier polyester yarn, ultrafine denier polypropylene yarn and so on.

The increase in surface area firstly causes the increase in the degree of adsorption and desorption of the dye during dyeing. The increase in the degree of adsorption leads to an increase in the dyeing rate, a decrease in wet fastness and light fastness, and a second cause to a decrease in the color concentration of the dyed fabric. Improving the dyeing properties of polyester microfibers and fabrics has become a topic of great interest for enterprises. In fact, ultrafine fiber is a kind of differentiated fiber that has 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 chemical fiber that is in a high-tech and high-simulation direction. Representative of the development of new synthetic fiber.

The ultrafine fiber monofilament fineness and the cross-section diameter of the monofilament are smaller than any natural fiber, and the thinner the fiber, the larger the number of fibers in the cross section of the same special yarn, and the larger the total surface area of the fiber. Although the strength of the monofilament is small, the total strength of the yarn is high; the flexural stiffness of the monofilament is low, and the structure of multiple monofilaments makes the microfiber fabric have excellent drape and soft feel ; Can use ultra-fine fibers to form a very tight fabric, so that its functionality is improved, waterproof, windproof, moisture permeability, heat insulation is improved, has a silk-like appearance, soft gloss. Fiber fineness has a direct impact on fabric surface coverage and fabric aesthetics. Due to the fineness of the ultrafine fiber and the small strength of the single fiber, the fabric is easy to fuzz and fuzz, which can form a fine fluff on the surface of the fabric. At the same time, more fibers can strengthen the surface cover and make the hand feel softer. The plush effect can be used for fabrics such as imitation suede and peach skin. The fineness of the ultrafine fiber is fine, and the total specific surface area of the fiber in the spun yarn is large, which is good for absorbing water. Compared with conventional fabrics, the porosity in the fabric is high. There are many capillaries or capillary systems, and the material itself is reused. The moisture regain rate allows moisture to be quickly absorbed, transferred, and diffused, so that the fabric has good moisture-conducting comfort.

Performance of microfiber

Due to the small diameter, the ultrafine fiber has a small bending stiffness, and the fiber feels particularly soft; the specific surface area of the ultrafine fiber is large, so the coverage, fluffy and warmth of the ultrafine fiber fabric are significantly improved, and the specific surface area is large The fiber has more contact with dust or oil, and the oil has more chance to penetrate through the gaps between the fiber surface, so it has a strong cleaning function; the ultra-fine fibers are made into ultra-high-density fabric, and the space between the fibers is between the diameter of the water droplets And the diameter of water vapor droplets, so the ultra-fine fabric has a good waterproof and breathable effect; ultra-fine fibers have many fine pores between the micro-fibers, forming a capillary structure, if processed into towels that can be wetted by water Fabrics are highly absorbent. Washed hair with this towel can quickly absorb water and dry hair quickly. Characteristics of microfiber
