  With the development of society and the improvement of material living standards and civilization, people’s requirements for the quality of life are also getting higher and higher, and higher requirements are also put forward for the cleaning of the environment, equipment and households, especially electronics, precision machinery and aerospace, hospitals and other industries. Precision testers and optical instruments are required to have a higher clean surface, and a clean cloth with excellent performance is required. At this time, all kinds of cleaning products in the past are more and more unable to meet people’s needs. Large companies have devoted themselves to the development of high-performance cleaning cloths made of microfiber fabrics. Microfiber high-performance cleaning cloths are more and more widely used because their wiping and cleaning efficiency is much higher than that of ordinary fiber cleaning cloths.
   Microfiber and its cleaning cloth Microfiber is one of the differentiated fibers that has developed rapidly in recent years. It is a new generation of synthetic fibers whose origin should be traced back to bicomponent composite fibers. From around 1960, Japan’s Zhongfang Company successfully trial-produced composite fibers with “skin-core” and “side-by-side” types. After 1988, Western Europe, the United States, South Korea, mainland China, and Taiwan Province successively produced and sold fine denier and ultra-fine denier fibers. and products. Microfiber, a high-tech, high-value-added product, has set off a global boom. Taken together, microfiber and its products have the following excellent properties. a) Geometric characteristics: The small diameter of the fiber brings about the “micro air chamber” effect, which makes the fabric have better moisture retention and sound insulation, and has obvious and special capillary phenomenon and wearing comfort, filtering, and “moisture-permeable and waterproof” when wearing. ” Features.
b) Mechanical properties: high specific strength, high strength, low elongation, high flexibility, and high torsion due to reduced fineness.

  This results in a significant reduction in flexural and torsional rigidity, so microfiber products have an extremely soft touch and excellent durability. c) Surface characteristics: The specific surface area of microfibers is larger than that of ordinary fibers, which improves the bulkiness and coverage of the fabric. At the same time, the gaps between fibers are large and dense, and their capillary action can be used to improve water and oil absorption properties so that they have good cleaning ability. There is a fined light) effect photo effect. Features: The number of fibers is large and the density is high.) Chemical properties: As for synthetic fibers, polyester, polypropylene, and other ultra-fine fibers have good chemical stability and the performance of inhibiting shellfish and seaweed. They can be used as enzyme supports, permeable membranes, Artificial blood vessels, artificial skin, and other biomedical fields. As a high-quality, high-tech textile raw material, microfiber not only has high-quality and comfortable wearing properties, but also is an optional fabric for medium and high-end clothing, and has also been widely used in biology, medicine, electronics, water treatment, and other industries.
2 Design of microfiber cleaning cloth 2∙1 Yarn requirements a) Fiber selection: Whether it is natural fiber or synthetic fiber, short fiber is easy to fall off compared to the filament and becomes a source of dust, so it is not suitable as a raw material for cleaning cloth. Among the filaments, silk, rayon, and acetate silk have low strength, such as long-term repeated use, which is easy to fluff and causes monofilament breakage due to friction during washing. Of course, if the organic conductive fiber is mixed, the cleaning cloth and the electrostatic cleaning ability will be used more widely. Considering that the fabric has to be sand washed and sanded, and the wool mainly acts on the weft fiber, the weft direction must use microfiber. The warp direction can use microfiber or fine denier polyester-drawn yarn.
b) Fiber fineness: The surface area of the fiber is inversely proportional to the fineness of the fiber. The finer the fiber, the larger the specific surface area, the stronger the cleaning ability. Both theory and experiment show that the linear density of microfiber used in high-performance cleaning cloth is generally 0∙11~0∙22dtex (0∙1~0∙2D).

  Fabric organization and specification design Clean cloth can be divided into three categories: woven fabric, knitted fabric, and non-woven fabric according to the manufacturing method. Traditionally speaking, high-performance cleaning cloths generally use woven fabrics, which are characterized by compact structure, high strength, good durability, and not easy to lint. The organization of the woven cleaning cloth basically adopts the three original organizations, and the fabric organization form mainly affects the smoothness of the surface of the fabric and the shape and size of the gap, thereby affecting the performance of the cleaning cloth. In order to obtain the desired appearance, the fabric is often brushed and sanded on both sides. Microfiber cleaning cloths with knitted structures have developed rapidly in recent years. The weft-knitted structure is soft, delicate, and has good elasticity; the warp-knitted structure has the characteristics of high production efficiency, stable size, and small detachment, so there are more and more warp-knitted clean cloths on the market.
