Historical evolution of non-woven bag fabric
First, the development of non-woven textile industry
As of 1998, the world's non-woven fabric consumption has reached 2.4 million tons. In 1970, its consumption was only 400,000 tons, and by 2007, its consumption is expected to reach 4 million tons.
Non-woven fabric producers are mainly concentrated in the United States (41% of the world), Western Europe accounts for 30%, Japan accounts for 8%, China's production accounts for only 3.5% of the world, and its consumption is 17.5% of the world. .
Man-made fibers still dominate the production of non-woven fabrics, and this situation will not change much until 2007. Of the fibers used in nonwovens production worldwide, 63% are polypropylene, 23% are polyester, 8% are viscose, 2% are acrylic, 1.5% are polyamide, and the remaining 3% are others. fiber.
The application amount of non-woven fabrics in sanitary absorbent materials, medical uses, vehicles, and textile materials for shoes has increased significantly.
Second, non-woven production and consumption
The global consumption of non-woven fabrics was 800,000 tons in 1983, and it 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. In 2005, its consumption could reach 3.7 million tons.
The consumption of man-made fibers for various textiles was 16.9 million tons in 1983, and increased to 20.4 million tons in 1988. It reached 30.4 million tons in 1998. It is estimated that by 2005, its consumption will be 37 million tons. It can reach 38.3 million tons per year.
The growth rate of man-made fiber consumption in non-woven fabric production is expected to reach 10% in 2005, and will reach 10.4% by 2007. Part of the reason for the soaring consumption of the nonwovens industry is the increase in auxiliary industries in China, Southeast Asia, Latin America and the Middle East.
Third, the factors affecting the growth rate of nonwovens
All factors affecting the growth of man-made fibers can have a certain impact on textiles made from rayon, which has the greatest impact on non-woven textiles. The population growth factor has less impact on non-woven fabrics than other textiles used in apparel. But if the important application of non-woven fabrics in baby diapers is taken into account, population growth is also an important factor. The replacement of the natural fiber portion has a greater influence on the textile, but has little effect on the nonwoven fabric because the production of the nonwoven fabric is basically dependent on the rayon.
The commercial development of man-made fibers and the professional application of non-woven fabrics: The trade in micro-fibers, composite fibers, biodegradable fibers and new polyester fibers has increased due to the establishment of international economic treaties. This has a great influence on non-woven fabrics, but has little effect on apparel and knitted textiles. Replacing textiles and other supplies: This includes being replaced by non-woven textiles, knitted textiles, plastic films, polyurea foams, wood pulp, leather, and the like. This is determined by the cost and performance requirements of the product. Introducing new, more economical and efficient production processes: the use of polymers to make a variety of articles, the application of competitive new nonwovens and the introduction of specialty fibers and nonwoven textile additives.
The three major fibers used in the production of nonwovens are polypropylene fibers (62% of the total), polyester fibers (24% of the total) and viscose fibers (8% of the total). Between 1970 and 1985, viscose fiber was the most widely used in the production of non-woven fabrics. Between 2000 and 2005, the use of polypropylene fibers and polyester fibers began to dominate in the field of sanitary absorbent materials and medical textiles. In the early days of nonwovens production, nylon was used in large quantities. Since 1998, the amount of acrylic fiber has started to rise, especially in the field of artificial leather manufacturing.
There are many large-scale projects in China's various construction projects, such as the Three Gorges Project, Xiaolangdi Project, environmental protection projects, western development, infrastructure construction, etc., which will greatly promote geotextiles, filter materials, waterproof materials, packaging materials. consumption. In addition, the increase in domestic consumer income will also effectively promote the consumption of various hygienic absorbent products and air filter materials, medical and health supplies and labor insurance and sports supplies. Therefore, the Chinese non-woven fabric industry has great growth potential in the future.
Disposables: Medical nonwovens are medical and sanitary textiles made from chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and fiberglass. Including disposable masks, protective clothing, surgical gowns, gowns, lab coats, nurse caps, surgical caps, doctor hats, surgical bags, maternity bags, first aid kits, diapers, pillowcases, sheets, quilt covers, shoe covers, etc. . Compared with traditional cotton woven medical textiles, medical nonwoven fabrics have the characteristics of high filtration efficiency to bacteria and dust, low surgical infection rate, convenient sterilization and sterilization, and easy compounding with other materials. As a disposable disposable product, medical nonwoven products are not only convenient, safe and hygienic, but also 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 is about 64 billion yuan, and it is developing in a diversified direction.
Flour fine bag: Flour bag made of non-woven fabric, which is light, environmentally friendly, moisture-proof, breathable, flexible, flame-retardant, non-toxic, non-irritating and recyclable. It is an internationally recognized environmental protection for the earth's ecology. Products, are widely used in various types of rice noodles, such as: wheat flour, corn flour, buckwheat flour. Rice and so on. This kind of non-woven products are printed with ink, beautiful and vivid, non-toxic, tasteless and non-volatile, more environmentally friendly than ink printing, fully satisfying the environmental protection requirements of modern people. Due to the reliable quality, affordable price and long service life. The main specifications are 1 kg, 2.5 kg, 5 kg, 10 kg and other specifications of rice noodle bags, bags and so on.
Fashion shopping bag: non-woven bag (also known as non-woven bag, English: Nonwoven bags) is a green product, tough and durable, beautiful appearance, good breathability, reusable, washable, silk screen advertising, hoe, It has a long service life and is suitable for any company or any industry for advertising and gifts. Consumers get a beautiful non-woven bag while shopping, and the merchants get intangible advertising, the best of both worlds, so non-woven fabrics are becoming more and more popular in the market.
