Glass fiber needle-felt cloth bag

Product introduction

Glass fiber needled felt bag is a kind of filtering material with reasonable structure and good performance. It is a felt-like nonwoven cloth filtering material made by using glass fiber as raw material and needling the carded short glass fiber felt with thorns. The fibers between felt glass fiber layers and between felt glass fiber layers and reinforced glass fiber base cloth are intertwined by mechanical method, and the fiber webs are reinforced.

Product characteristics

1. Good heat resistance: glass fiber needled felt can withstand the high temperature below 260℃ for a long time, which is an important characteristic of the general fiber and synthetic fiber, but also the internal factor of its increasing dosage in the field of high temperature filtration year by year. The temperature of glass fiber needled felt can reach 287℃ for a short time.

2.Size stability touch good: Xuan glass brazed dimension needle felt not only good heat resistance, dimensional stability is good, shrinkage rate is equal to zero.

3。Filtration, resistance is small: fabric filter cloth is a kind of flat structure filter material, filter unit is yarn, the porosity between the warp and weft yarn line is large, at the beginning of filtration or filtration speed is high, easy to produce filtration phenomenon. The needled felt is a kind of filter material with body type structure. The filter unit is single fiber with numerous fibers interleaved together and very small pores. Moreover, its filtration process does not occur on the surface layer, but also in the interior of the filter material, therefore, needle felt filter material filtration.
