Non-woven fabrics are also called non-woven fabrics and non-woven fabrics.
It is a new type of fiber product with soft, breathable and flat structure. It has many types, and imported spunbond filament non-woven fabric is one of them.
The main reason for incomplete melting of low-melting-point fibers is insufficient temperature. For non-woven fabrics with low basis weight, the problem of insufficient temperature is usually not easy to occur. However, special attention must be paid to products with high basis weight and high thickness. Is it enough?
The non-woven fabrics located at the edges are usually thicker because they have enough heat. The non-woven fabrics located in the middle part are prone to insufficient heat to form thinner non-woven fabrics. Imported spunbond filament non-woven fabrics The cloth is made of 100% pure fiber by needle punching method to form a highly fluffy filter layer with three-dimensional depth.
It is characterized by loose fiber structure and high porosity, which increases the amount of impurities held. It is a compound interception mode that can effectively remove solid and soft particles. Larger particle impurities are trapped on the surface of the fiber, while fine particles It is captured in the deep layer of the filter material, so it has high filtration efficiency.
Imported spunbond filament non-woven fabrics are prepared using unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
