How to judge the quality of needle punched non-woven fabrics

Needle-punched non-woven fabric is one of dry-laid non-woven fabrics. The net is repeatedly punctured, and the hook and belt fibers are reinforced to form a needle-punched non-woven fabric. Typical products: synthetic leather base fabrics, needle-punched geotextiles, etc.

Needle-punched non-woven fabrics have been used in all walks of life, especially in agriculture, aquaculture, industry, construction, and needle-punched non-woven fabrics. Features, by the common people and the majority of users like.

As the thickness increases, the air permeability of the packaging material will also be affected, and the probability of wet packs will also increase. Using a thickened non-woven fabric, the increase in the weight of the spunbond layer cannot effectively increase its antibacterial performance. Only when the pore size of the key filter layer (ie, the meltblown layer) can effectively filter the intrusion of microorganisms and dust, its antibacterial performance meets the requirements. An increase in thickness does not imply an increase in the barrier properties of microorganisms. The increase in the thickness of the non-woven fabric means that the weight per unit area increases, and the strength also increases, but due to the structure. Non-woven fabrics are not divided into warp and weft, and the fibers of the fabric are disordered, and the performance of warp and weft is not very different. The needle has a barb, the fiber web is repeatedly punctured, and the hook belt fiber is reinforced to form a needle-punched non-woven fabric. Needle-punched non-woven fabrics are made by opening, carding, and laying short fibers into fiber webs, and then reinforcing the fiber webs into cloth through felting needles.
