Use
The main applications of needled nonwovens are carpets, decorative felts, sports mats, mattresses, furniture mats, shoes and hats, shoulder pads, synthetic leather base fabrics, coated base fabrics, ironing mats, wound dressings, Artificial blood vessels, heat pipe sleeves, filter materials, geotextiles, paper felts, linoleum base fabrics, sound insulation materials, and automotive decorative materials.
At present, the use of acupuncture machines in high temperature filtration products is relatively large. The high-performance fibers of high-temperature filtration products mainly include glass fiber, Nomex fiber, P84 fiber, PPS fiber, and PETT fiber. Due to the characteristics of the first few fibers, the scope of use has been affected. glass fiber
More brittle, Nomex fiber is poor in oxidation resistance, P84 fiber is easily hydrolyzed and aged, and PPS fiber is used at a lower temperature. PETT fiber is resistant to chemical corrosion and high temperature, can be used in a variety of harsh environments and achieve better results, and has a longer service life than filter materials made of other fibers.
Although PETT has good temperature and chemical resistance, it is expensive and has no advantage in filtration efficiency compared to other fibers. To this end, some companies add an appropriate amount of ultra-fine glass fiber, which does not affect the temperature resistance performance, but also improves the filtration efficiency of the filter material and reduces the price of the material, and also expands the scope of application and prolongs the service life.
