Needle Punched non-woven fabric is a kind of dry nonwovens, is paved with short fibers after opening, carding and netting, then put the web through the pricker reinforcement into cloth, needle hook, the web of repeated puncture, hook fiber reinforcement, form the Needle Punched non-woven, non-woven no warp weft, into the cloth fiber mixed and disorderly, warp weft to performance.Typical products: synthetic leather base fabric and nonwoven fabric, etc.
Commonly used specification:
Weight:100-1000g per ㎡,
Thickness: ≥ 5 mm
Width: 210 cm or less
Based on polyester, polypropylene raw materials manufacturing, carded and combed, Needle Punched, master of Needle Punched.Center and network cloth sandwich, then through double rationalized, airflow into the net Needle Punched composite cloth, filter cloth has a three-dimensional structure, after the heat setting, singeing, oil on the surface of the chemical agent processing, make the filter cloth surface smooth, uniform pore distribution, on the surface of the product density is good, two sides smooth surface and air permeability is good, in the plate and frame filter used on compressor proved that, can use high pressure, 4 micron filtration precision of less than, can according to user needs to provide polypropylene and polyester materials.Practice shows that non-woven filter cloth on a plate and frame filter performance better, coal preparation plant of coal slurry treatment, steel mill waste water treatment.In a brewery, and dyeing wastewater treatment.As with other specifications will be the press filter cake, filter cloth and hard to fall off, with non-woven filter cloth, filter cake on the filter pressure reached 10 kg - 12 kg is very dry, and open frame filter press filter cake will automatically fall off.User when choosing non-woven filter cloth, mainly according to the air volume, filtering precision, elongation, etc to consider different thickness, the quality of non-woven filter cloth, product parameters, please point polyester fiber needled felt and polypropylene fiber needled felt, specifications varieties can be formulated.
Needle Punched non-woven series products are through the careful combing molding, multiple precision needle or properly in hot rolling.In introducing two high-precision needle production line at home and abroad, on the basis of choosing high quality fiber.Through different production process, and the supplement of different materials, circulation, hundreds of different products on the market at present, which mainly include: geotextile, geomembrane, ji flannelette, speakers blanket, electric blanket, cotton, cotton, cotton clothing, embroidered handicrafts, Christmas leather base cloth, filter material is special cloth.
Production of non-woven fabric by Needle Punched method is entirely through a mechanical function, namely the needle puncture needle machine, held the fluffy fabric reinforced by strong.
The basic principle is:
Using triangular cross-section (or other section) against the fabric edge sideband barbed thorns repeated puncture.Barb through the fabric, the fabric surface and local layer fiber forced to Pierce the fabric inside.Due to the effect of friction of the fiber between, fluffy fabric is compressed.Exit pricker fabric, Pierce the fiber bundle without barb in fabric, in this way, many catches hold of the bundle fiber web can't make it to restore the original state of fluffy.After many times of Needle Punched, a considerable amount of fiber bundle was stabbed into the fabric, the fabric of fiber entanglement with each other, thus forming has certain strength and thickness of needle punching nonwoven materials.
