Difference between non-woven fabric and dust-free fabric

Non woven fabric, also known as non-woven fabric, is a new generation of environmental protection materials, which has the characteristics of water repellent, breathable, flexible, non combustion supporting, non-toxic, non irritating, rich colors and so on. If the non-woven fabric is placed outdoors and decomposed naturally, its maximum service life is only 90 days. If it is placed indoors and decomposed within 5 years, it is non-toxic, tasteless and free of any residual substances during combustion, so it does not pollute the environment and is suitable for washing. It directly uses polymer chips, short fibers or filaments to form new fiber products with soft, breathable and planar structure through various fiber mesh forming methods and consolidation technologies. It has the environmental protection performance that plastic products do not have, and its natural degradation time is far lower than that of plastic bags. Therefore, non-woven bags made of non-woven fabrics are also recognized as the most economical and environmentally friendly shopping bags.

The dust-free cloth is double woven from 100% polyester fiber. The surface is soft, easy to wipe the sensitive surface, and does not remove fiber when rubbing. It has good water absorption and cleaning efficiency. The cleaning and packaging of products are completed in the super clean workshop. The optional edge banding of dust-free cloth generally includes: cold cutting, laser edge banding and ultrasonic edge banding. Superfine fiber dust-free cloth is usually perfectly sealed by laser and ultrasonic; The dust-free cloth, dust-free wiping cloth, ultra-fine fiber dust-free cloth and ultra-fine fiber wiping cloth are made of 100% continuous polyester fiber double woven cloth. The surface is soft and can be used to wipe sensitive surfaces. The dust production is low and the friction does not remove the fiber. It has good water absorption and cleaning efficiency. It is especially suitable for dust-free purification workshop. The edges of dust-free cloth, dust-free wiping cloth, ultra-fine fiber dust-free cloth and ultra-fine fiber wiping cloth are sealed by the most advanced edge cutting machine, which will not leave particles and thread ends after wiping, and has strong decontamination ability.

Historical background of non-woven fabrics

1. Development of non-woven textile industry

By 1998, the consumption of non-woven fabrics in the world had reached 2.4 million tons. In 1970, its consumption was only 400000 tons. By 2007, its consumption is expected to reach 4million tons. The producers of non-woven fabrics are mainly concentrated in the United States (accounting for 41% of the world), Western Europe accounts for 30%, Japan accounts for 8%, and China's output only accounts for 3.5% of the world, but its consumption is 17.5% of the world. In 2018, China's non-woven fabric output was 5.9322 million tons, accounting for 37.91% of the global total, ranking first in the world.

Man made fibers still dominate the production of non-woven fabrics, and this situation will not change significantly until 2007. Worldwide, 63% of the fibers used in the production of non-woven fabrics are polypropylene, 23% are polyester, 8% are viscose, 2% are acrylic, 1.5% are polyamide, and the remaining 3% are other fibers.

The application of non-woven fabrics in sanitary absorbent materials, medical materials, transportation vehicles and textile materials for footwear has increased significantly.

The global consumption of non-woven fabrics was 800000 tons in 1983, increased to 1.1 million tons in 1985 and 1.4 million tons in 1988. By 1998, the global consumption of non-woven fabrics reached 2.4 million tons. It is estimated that by 2005, the consumption will reach 3.7 million tons.

The consumption of man-made fiber for various textiles was 16.9 million tons in 1983, increased to 20.4 million tons in 1988, reached 30.4 million tons in 1998, and is expected to be 37 million tons in 2005 and 38.3 million tons in 2007.

The consumption growth rate of man-made fiber in non-woven fabric production is expected to reach 10% by 2005 and 10.4% by 2007. Part of the reason why the consumption of non-woven fabric industry increases so fast is the increase of auxiliary industries in China, Southeast Asia, Latin America and the Middle East.

3. Factors affecting the growth rate of non-woven fabrics

All the factors that affect the growth of man-made fiber can more or less affect the textiles with man-made fiber as raw material, among which non-woven fabrics have the greatest impact. The influence of population growth on non-woven fabrics is smaller than that of other textiles used for clothing. However, if we consider the important application of non-woven fabrics in baby diapers, population growth is also an important factor. The partial replacement of natural fibers has a great impact on textiles, but has little impact on non-woven fabrics, because the production of non-woven fabrics basically depends on man-made fibers.

Commercial development of man-made fibers and professional application of non-woven fabrics: due to the establishment of international economic treaties, the trade of microfiber, composite fiber, biodegradable fiber and new polyester fiber has increased. This has a great impact on non-woven fabrics, but has little impact on clothing and knitted textiles. Replace textiles and other products: This includes non-woven textiles, knitted textiles, plastic films, polyurea foam, wood pulp, leather, etc. This is determined by the cost and performance requirements of the product. Introduce new, more economical and effective production processes: that is, the production of various articles from polymers, the application of competitive new non-woven fabrics, and the introduction of special fibers and non-woven fabric textile additives.

The three major fibers used in the production of non-woven fabrics are polypropylene fiber (62% of the total), polyester fiber (24% of the total) and viscose fiber (8% of the total). From 1970 to 1985, viscose fiber was most widely used in the production of non-woven fabrics. From 2000 to 2005, polypropylene fiber and polyester fiber began to dominate in the field of sanitary absorbent materials and medical textiles. In the early non-woven fabric production market, the amount of nylon was very large. Since 1998, the amount of acrylic fiber began to rise, especially in the field of artificial leather manufacturing.

There are many large-scale projects in China, such as the Three Gorges project, Xiaolangdi project, environmental protection project, western development, infrastructure construction, etc., which will greatly promote the consumption of geotextiles, filter materials, waterproof materials and packaging materials. In addition, the increase of domestic consumers' income will also strongly stimulate the consumption of various sanitary absorbent products, air filter materials, medical and health supplies, and labor protection stationery. Therefore, China's non-woven industry still has great growth potential in the future.

Main products of non-woven fabrics

Disposable products

Medical non-woven fabric products are medical and health textiles made of chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber. It includes disposable masks, protective clothing, surgical clothing, isolation clothing, experimental clothing, nurse hats, surgical hats, doctor hats, surgical bags, maternity bags, first aid kits, diapers, pillowcases, bed sheets, quilt covers, shoe covers and other disposable medical consumables. Compared with traditional pure cotton woven medical textiles, medical nonwovens have the characteristics of high filtration of bacteria and dust, low surgical infection rate, convenient disinfection and sterilization, and easy compounding with other materials. Medical nonwovens, as disposable products, are not only convenient to use, safe and hygienic, but also can effectively prevent bacterial infection and iatrogenic cross infection. In China, the investment in the medical and health industry has reached more than 100 billion yuan, of which the total output value of sanitary products and materials has reached about 64 billion yuan, and is developing towards diversification.

Flour hardcover bag
