The main application field for pp non-woven fabric

Non-woven fabric has high economic benefit, its variety, widely used, its raw materials not only include the natural fibers such as cotton, also includes the viscose, chemical fibers such as polypropylene, nonpoisonous and harmless, and color is rich, have extremely strong wear resistance, acid-proof alkaline, and chemical corrosion resistance, and won't mildewy, bug eat by moth, is one of the largest production in the non-woven fabric. Look from the functional division, can be divided into the antibacterial, hydrophilic, anti-static, anti-aging, flame retardant, such as category, mainly used in medical and health care, health care, agriculture and industry, construction, civil and family decoration etc. This paper mainly studies the anti-aging type, the application of PP non-woven fabric and summarized as follows: 1, geotechnical greening PP non-woven fabrics because of its strengthening alkali acid resistance, resistance to mildew and bug eat by moth, decomposition resistance, weathering resistance, not easy to deformation characteristics, widely used in the geotechnical field. And the storage and transportation is convenient, the price is relatively cheap, look from its function, including strengthening, isolation, filtration, drainage, etc. , can be applied to the dam construction and railway, airport and highway facilities construction. Among them, in terms of railway construction, can be combined with its characteristics, to effectively solve the mud pumping of roadbed and other risks; In the dam construction, by laying such geotextile can effectively resist the soil erosion, to avoid the bank collapse and used in the underground drainage, retaining wall and soft soil foundation drainage construction process [ 1] 。 In addition, in the urban construction, anti-aging PP non-woven can be used for green planting lawn, not only less harmful to the environment, but also can heat preservation, facilitate irrigation, even in the period and withered and yellow phase can also make the lawn full of vitality, and convenient maintenance, can reduce the intensity of construction, and promote the lawn beautiful degree, reusable. Of course, this kind of fabric can also be used slope protection of highway greening and mountain rock to spray and sow grass. 2, agricultural past agricultural PP non-woven fabric under the long time of sunlight, prone to aging, cracking and other phenomena, shorter life cycle. And anti-aging type of PP non-woven fabric is made of polyester, PP raw materials such as processing of PP content is higher, not to the water or air has strong penetrability, and permeable chemical structure is relatively loose, can be used together with the agent of pesticides, chemical fertilizers, etc. In addition, anti-aging type PP non-woven fabric has good microclimate regulation, can not only heat insulation, heat preservation, can effectively resist ultraviolet ray, thus effectively improving plant growth environment. Looked from the field of agricultural production, mainly for the cover crop, plant growth substrate, greenhouses, farmland soil and water protection, etc. Due to the low cost of anti-aging type PP non-woven, and machining process short, good toughness, strength, has a good mechanical performance, can be repeated use, easy to recycle, etc. , thus providing guarantee good for farming. 3, in addition to the construction industry and agriculture industrial production field, anti-aging type PP non-woven fabric because of its fits the characteristics of environmental friendly, has been widely used in industrial production, including ceiling, sound insulation and heat insulation inner decoration, automobile dashboards, hood lining. Especially in car inner decoration, because many manufacturers want to use the strong durability, corrosion resistance of the material, rather than not recycled foam instead of, therefore, anti-aging type PP nonwoven is applied. , of course, in other areas, such as outdoor billboards, outdoor sportswear, sun hat, sunshade product and tents, outdoor home textile, anti-aging type PP non-woven fabric also has a broad application space.
