Polyester spunbond nonwoven fabric has high strength, good high temperature resistance (can be used for a long time at 150 ℃ environment), aging resistance, UV resistance, high elongation, good stability and breathability, corrosion resistance, sound insulation, mothproof, Non-toxic. Tell us about the main uses of polyester spunbond nonwoven fabric:
1. Household items: fabric softener and additives, vacuum cleaner bags.
2. Packing: cable covering cloth, tote bag, container bag, and packaging material.
3. Decoration: wall decoration cloth, floor leather base layer, electrostatic flocking base cloth.
4. Agriculture: agricultural harvest cloth, crops and plant protection, weed protection belts.
5. Waterproof material: high-grade breathable (wet) waterproof material base fabric.
6. Industrial applications: filter materials, insulation materials, electrical appliances, reinforcement materials, support materials.
7. Automobile decoration materials.
8. Others: composite film base cloth, baby and adult diapers, sanitary napkins, protective equipment, etc., disposable hygiene materials.
Market and Application of Polyester Spunbond Nonwoven Fabric Products
Building materials include a wide range of materials. The materials involved in the use of spunbond nonwovens mainly refer to roof waterproofing materials, followed by wall insulation and sound insulation, wall base waterproofing, pipe protection, underground drainage and prevention of tree root growth. Materials that infringe on buildings and other uses. Currently in China, applications are mainly concentrated in the field of roof waterproofing materials.
In the European and American countries, especially in Europe, this kind of waterproof material with excellent performance has been widely used since the late 1980s and early 1990s. Its market share has reached more than 40%, and most of them are PET spunbond tire bases. The application of polyester linoleum tire base in China started late, and the amount used in 2000 was only 20 million m2. However, since the beginning of the new century, new waterproof materials have developed rapidly. By 2002, the application volume of modified asphalt waterproof coiled material based on PET fiber was 70 million m2, and continued to grow. It is predicted that in the next 5 years, the modified asphalt waterproof coiled material will still develop at a relatively rapid rate, and the proportion of the total volume will increase to more than 20% by 2010. The potential market of new waterproof materials in China is very large (about 800 million to 1 billion m2). With the continuous development of China's economic construction, PET spunbond linoleum tire base has optimistic development prospects.
The application of geotextile abroad started as early as the 1960s. The United States is the world's largest consumer of geotextiles. In the early 1990s, its annual consumption was more than 300 million m2, and in recent years the consumption reached 700 million m2. . Geotextiles in Europe and Japan have also developed rapidly. The annual usage of geotextiles in Europe is also about 400 million m2 in recent years, of which spunbond nonwoven fabrics account for about 60% of nonwoven geotextiles; Japan in the mid-1990s The application of geotextiles will increase significantly in the future. Among the nonwoven geotextiles in Japan, the amount of spunbond method is the largest, accounting for about 60% of the total amount of nonwoven geotextiles, and it is mainly PET spunbond cloth.
The geotextile in China started in the early 1980s, but the amount used was very small at that time, and it was only an experimental application. It was not until the 1998 flood that caused the government's attention that the construction department included the application of geotextiles in the design specifications and formulated relevant national standards. Geotextiles were truly valued and developed. At present, the amount of geotextile in China has exceeded 300 million m2, and the proportion of non-woven geotextile has reached about 40%. China's civil engineering construction has a huge potential market, and its potential is never lower than the current US consumption of 700-800 million m2. Experts estimate that China's geotextile will continue to grow in double digits in the next 15 years, among which the faster growth rate is PET spunbond filament geotextile.
During the period from the Tenth Five-Year Plan to the Eleventh Five-Year Plan, China plans to invest heavily in various projects such as water conservancy, power, transportation, environmental protection, and river management, including water conservancy construction, South-to-North Water Diversion Project, power investment, highway and railway Construction, environmental engineering, as well as ports, airports, garbage disposal, rivers, lakes and seas management, sand control and other projects, the investment amounted to trillions of yuan. In the next 10 years or more, China will have more infrastructure projects to be built, and there will be more and more demand for geotextiles. China will become the world's largest marketing market for geosynthetics.
Domestic PET spunbond nonwoven production capacity
At present, China has about 9 PET spunbond production lines, with a total production capacity of about 31,000 t / a, including Yizheng Nonwoven Fabric Factory, Hunan Nonwoven Fabric Factory, Henan Sanli Company, Shanghai Jiasi Maiwei Company, Jiangxi Guoqiao In order to introduce production lines from Italy or West Germany, Shaoxing Lida, Xinjiang Tianli, Xichuan Nonwoven Fabric, Dalian Hengda, Zhejiang Yongguang Nonwoven Fabric Factory and other domestic production lines have a minimum width of 2.4m and a maximum width of 6m. . The maximum production capacity of these production lines is 4500 t / a, and the minimum production capacity is 1000 t / a. The 4.5m wide PET spunbond geotextile and linoleum base fabric production line designed and manufactured by Xinjiang Tianli Company designed and manufactured by the Nonwoven Fabric Technology Development Center of the textile industry is a domestically produced equipment with the highest product quality and the best quality. The production capacity reaches 3500 t / a.
At present, the main products produced by these production lines include geotextiles, engineering impervious materials, building waterproofing materials, composite reinforcement materials, automotive fabrics, cushioning materials, chemical sheets for shoes, etc. The prospects are very impressive.
Home textiles and composite materials
According to the characteristics of aging resistance and high temperature resistance of spunbond nonwoven fabrics, it is widely used in home textiles, composite materials, luggage materials, etc. Through high-temperature transfer printing, high-end and affordable cloth is produced; and because of its aging resistance; it is widely recognized by consumers.
