1. Building Materials
The products are widely used as construction materials, mainly including composite roof waterproof, soundproof walls, insulation, wall-based waterproofing, pipe protection, underground drainage and root growth preventing against etc.
Application of Polyester bitumen-substrate nonwoven began around the early 90s of last century, mainly including SBS, APP modified bitumen waterproof substrate nonwoven by staple needle-punched and PET spunbonded needle-punched process. There is also waterproof materials by using PP spunbonded non- woven as cooling coated substrate. Since these products appear recently, they are not fully used in the market. But they could be potential materials with its predominant heat resistance and weather ability in the aspect of heat and sound insulation for construction walls, wall-based waterproofing, pipe protection, underground drainage and root growth preventing against buildings, etc. PET spunbonded material can be more suitable in this field.
2 Geo-textiles materials
The use of geo-textile began in the early 80s in and consumption of geo-textile is over 200 million m2 by 2001 in China, in which the proportion of the non-wovens is more than 40%. According to the demand of construction in later 20 years, geo-textile consumption will have an annual growth rate of 50% or more, and consuming growth of PET spunbonded geo-textile will be faster.
At present, China's largest amounts of non-woven geotextile are PET staple needled-punched non-wovens and PET spun-bonded non-wovens. PET spunbonded non-wovens is mainly used for drainage board, filter separators and enhanced composite geo-textiles. At present the application of the quantity was small, but potential uses are large.
3 carpet substrate
Carpet products are mainly tufted and acupuncture carpet in China. To the mid-and late 90s, tufted carpet got rapid development. At present, production and sales volume of tufted carpet in China is about 100 million m2.
So far in China a large proportion of tufted carpet fabric still follows the traditional way, PET spunbonded nonwovens used for carpet substrate still has a small proportion , According to incomplete statistics, China's imports of PET spun-bonded carpet substrate quantity is about 1000～1800 t. PET spunbonded nonwoves used for such purposes has character of coarse denier (about 10 ~ 15d or so), Oil on stiffness, high strength, flexible small and hot-calender products by plane roller
4 Auto Interior Trim Materials
Automobile industry in China is a rapidly developing pillar industry in recent years. At present, China auto production and sales have more than 7 million.
Automotive textiles include automotive carpets, headlining, hood lining, automotive filter materials, luggage liner, car seat cover and door panel trim material. Automotive Textile is more used in car trim, generally 25m2 fiber used for a car According to the present China's car output, if 10% of them adopt tufted carpet, requirement of spunbonded substrate for tufted carpet will amount to approximately 6 million m2. Textile is also popular used in roof and hood lining. In Japan', 80% of the roof material is non-wovens.
The field of automotive filters is also a larger market, It is estimated that automotive non-wovens will be up to 350 million m2, and automotive filter materials more than 100 million m2 in the world'sby 2010. PET spunbonded hot-calender nonwovens can be used widely in the field of air filter materials for cars and buses. At present the use of PET spunbonded nonwovens is about 250,000 m2 in China. If there are 400 million cars in China, the demand of PET spunbonded nonwovens using as air filtration materials will be at least 1.2 million m2.
5 Agricultural cloths
In recent years, China's agriculture textile application has been gradually increased. Agricultural non-woven cover material will reach an annual amount of 160,000 t in 2010 according to the estimation. PET spunbonded hot-calender non-wovens is the most suitable material for agricultural use. Its anti-aging, weather-ability is more superior than PP spun-bonded nonwovens and its life is about 3 times longer than PP spun-bonded nonwovens. Its specification in agricultural use is commonly at 10 ~ 70 g /m2.
6 Packaging Materials
Packaging Textiles (including non-wovens) has developed rapidly since the 21st century. With double-digit growth every year, the growth was mainly attributable to a lot of paper packaging replaced by textile, non-woven materials and composite materials of paper and non-woven materials in the past, including garment bags, shoe bags and so on. Some department stores and exhibition spaces has also adopted non-woven bags to replace paper and plastic shopping bags, information packs, packing bags and so on.
At present, most nonwovens packing materials are PP spunbonded nonwovens or other materials which are composited by PP nonwovens and paper, or pp nonwovens and plastic. But PET spun-bonded nonwovens can be used to meet some special requirements, like fine dyeing, printing packaging materials, such as high-grade garment bags, boutique bags and so on.
7 Travel, toiletries
In more than 10 years ago, some people utilized spunbonded nonwovens and spunlaced nonwovens to produce travel underwear, travel hats, tents, sauna clothes and so on. In recent years, with the rapid economic development in China, tourism and recreation have vigorous development and demand of tourism products and bath supplies continues its increasing. In recent years, during the period of "5.1", "10.1" long vacation, the number of tourist has gone beyond 100 million persons one-time, so travel goods has a huge market.
8 Decorative Materials
Non-woven has extensive use in decorative area, such as curtains, blinds, and pasted Wall Cloth, Table cabinet cladding fabrics and paintings, artificial flowers, etc. Dye ability of PET fibers is much better than PP, since PET spun-bonded nonwovens can produce beautiful decorative products with bright pattern through dye printing system to beautify the indoor environment. In recent years, there is a fashion in foreign countries to produce shutter shade by spunbonded nonwovens. China has begun to develop the same products and this will have broad development prospects. At present, several spunbonded PET hot-calender enterprise have developed these products and to expand sales in China.
9 Industrial Protective Clothing
Protective clothing is a high-end, high-tech, and high value-added products, including chemical protective suits, smelting temperature with anti-protective clothing, anti-radiation protective clothing, anti-electromagnetic protective clothing, anti-asbestos-protective clothing, room cleaning and anti-dust clothing, medical ambulance service, bullet-proof clothing, paint work clothes, etc. According to their use, most of these products has strict requirements against the permeability. For the strict requirements, the products are produced by high-density polyethylene flash spun non-woven or woven fabric through composite or coating system. But for the liquid infiltration of anti-chemical warfare suits, ambulance service and paint work clothes, etc. PET spun-bonded nonwovens can be used. DuPont uses a low viscosity of the polyester (PET) to developed superfine spun-bonded nonwovens for protective clothing with its good nature of permeability and effective anti-liquid permeability.
10 Filter materials
Spunbonded non-woven can also be used as filter applications. This is a high technological content and added value area. The use of Spunbonded non-woven, in most cases is based on a composite form, primarily to have strengthening role. In a few special usages, it is also used alone. In normal circumstances, people are more willing to use the PP spunbonded nonwovens, but PP spun-bonded nonwovens softening point and melting point are very low, only in an environment below 90 ℃, and at the range of 90 ℃ to 200 ℃, PET spun-bonded nonwovens is the best-reinforced composite materials. Currently some foreign multinational companies are using PET spun-bonded nonwovens to develop filtering materials (including automotive filters). Development of such products will choose even net uniform and finer denier materials.
11 Composite materials and others
Non-woven products are no longer single-mass-string, non-woven with a wide range of end-use has begun to adopt a comprehensive performance of the composite material. For example, to develop ultra-thin and moisture adjustment function composite materials
by taking advantage of PET spun-bonded nonwoven, composite acrylic acid salt particles and 2 pieces of PET spunbonded non-woven together to produce cushions, sofas , mattress, car seat cover, construction materials, insoles and so on.
Some products, such as electrostatic flocking foundation fabricat and others could use PET spunbond fabrics as their material. If the PET spunbond fabric can have a breakthrough in the uniformity, softness, anti-permeability, etc., it could be used to produce leather cloth, wire and cable knitted fabrics and garments lining cloth.
PET spunbonded noonwovens can also be used to make battery clapboard, geothermal heating plate, and inkjet printing display media, sound-absorbing material, fiber fabric and anti-static fabric, etc
