Non-woven fabric, also called non-woven fabric, is a fabric that does not require spinning and weaving. There are many types of it on the market, and imported filament non-woven fabric is one of its many types. kind.
Commonly used non-woven materials are polypropylene (PP in English, commonly known as polypropylene) non-woven bags or polyethylene terephthalate (PET in English, commonly known as polyester), which are environmentally friendly and ordinary plastic shopping bags Likewise, they cannot be completely degraded.
In terms of specific cost performance, non-woven bags under the same conditions are not as strong as plastic bags and are not waterproof, and their prices are several times higher than plastic bags.
Imported filament non-woven fabrics have good heat resistance, with a melting point of 164~170°C, and the products can be sterilized at temperatures above 100°C.
It will not deform at 150℃ without being affected by external force.
The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE.
It also has good chemical stability. In addition to being corroded by acids, it is relatively stable to various other chemical reagents. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can soften and swell the non-woven fabric. Chemical stability It also improves with the increase of crystallinity.
Suzhou ptfe filter membrane manufacturer supplies imported filament non-woven fabrics, and the polytetrafluoroethylene microporous membrane we produce is prepared using unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities, and at the same time has a relatively high Large throughput.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
