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

Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric, which is to open, card and spread short fibers into a fiber web, and then reinforce the fiber web into a cloth with needles. The needles have barbs, and the fiber webs are repeatedly punctured. , Hook belt fiber reinforcement, forming needle punched non-woven fabric, non-woven fabric has no warp and weft, the fabric fiber is messy, and the warp and weft performance is not much different. Typical products: synthetic leather base cloth, needle-punched geotextile, etc.


Needle-punched non-woven fabrics have been used in various industries, especially agriculture, aquaculture, industry, and construction. Needle-punched non-woven fabrics have many characteristics such as low cost, economical application, convenient and simple use, and environmental protection. The common people and the majority of users like it.


As the thickness increases, the air permeability of the packaging material will also be affected, and the probability of wet packs will increase. Using a thick non-woven fabric, the increase in the weight of the spunbond layer can not effectively increase its anti-bacterial performance. Only when the pore size of the key filter layer (ie the melt blown layer) can effectively filter the intrusion of microorganisms and dust, it can prevent bacteria Performance meets the requirements. The increase in thickness does not mean 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 will also increase, but due to the structure. Non-woven fabrics are not divided into warp and weft, the fibers of the fabric are messy, and the warp and weft performance is not much different. The felting needle has barbs, and the fiber web is repeatedly pierced, and the hooks are reinforced with fibers to form a needle-punched non-woven fabric. Needle-punched non-woven fabrics are made by opening, carding, and spreading short fibers into a fiber web, and then the fiber web is reinforced by felting needles to form a cloth.
