The polyester clean cloth industry in my country started late, mainly after the 1980s. With the national industrial policy listing the electronic information industry as an important national development direction, the color TV, computer, communications, integrated circuit and other industries have entered rapid development At the same time, the introduction of a large amount of foreign investment puts forward new ultra-clean concepts and requirements for the microelectronics production environment, which has accelerated the rapid development of the industry.
Polyester dust-free cloth is a clean room wiping cloth made of 100% continuous polyester fiber filaments. It has a grid structure, excellent water and oil absorption performance, and extremely low ion residue, which can effectively prevent dust particles and fibers. Dispersion; the surface is soft, wear-resistant, has an efficient cleaning and wiping ability, and is suitable for cleaning and wiping sensitive surfaces. Polyester dust-free cloth is an ideal material for cleaning applications in high-level clean rooms. It is widely used in semiconductor production lines, microelectronics production lines, semiconductor assembly production lines, disc drive composite materials, LCD display products, circuit board production lines, precision instruments, Optical products, aviation industry, PCB products, medical equipment, laboratories and other fields.
According to the classification of purification level, polyester dust-free cloth can be divided into: 100-level dust-free cloth, 1,000-level dust-free cloth, and 10,000-level dust-free cloth; according to the classification of functions, polyester dust-free cloth can be divided into: nuclear industry Dust cloth, anti-radiation dust-free cloth, photoelectric dust-free cloth, PCB dust-free cloth, anti-static dust-free cloth, conductive dust-free cloth, etc.; according to the size and packaging classification, the conventional packaging of polyester dust-free cloth is 9*9 inches , 6*6 inches, 4*4 inches, etc.; according to the edge banding, it can be divided into: laser edge banding, ultrasonic narrow edge banding, ultrasonic wide edge banding and thermal cutting edge banding.

In recent years, in the field of semiconductor integrated circuits, the state has provided support from various aspects such as tax incentives, investment approvals, equipment imports, land plants, etc., attracting a number of leading IC companies including Intel, TSMC, SMIC, Samsung Semiconductor, etc. Domestic investment in the establishment of factories and project expansion; in the field of pharmaceutical manufacturing, the implementation of the new version of GMP standards has greatly increased the demand of domestic pharmaceutical companies for the upgrading of clean room and clean cloth products. In 2018, the domestic polyester clean cloth industry market reached 2.765 billion yuan.
At present, domestic polyester clean cloth production enterprises are mainly distributed in the Beijing-Tianjin-Hebei region, the Yangtze River Delta and the Pearl River Delta, which have convenient transportation, developed economy and convenient supply of raw materials. There are a large number of production enterprises in the industry, most of which are small in scale. The products with low cleanliness level have serious homogeneity, low concentration and fierce competition; products with high cleanliness level have stricter production environment and technical requirements, and the market is concentrated Degree is relatively high, and competition is relatively moderate.
