针刺无纺布是干法非织造布中一种，是将短纤维经过开松、梳理、铺成纤维网，然后将纤维网通过刺针加固成布，刺针有钩刺，将纤维网反复穿刺，钩带纤维加固，形成针刺无纺布，无纺布没有经线纬线之分，成布纤维杂乱，径向纬向性能差别不大。典型产品：合成皮革基布、针刺土工布等。

Acupuncture is a kind of dry non-woven non-woven cloth, is the short fibers by opening, carding, Pu fiber network, then the fiber mesh reinforcement into cloth by a needle, needle hook, fibre mesh hook with repeated puncture, fiber reinforcement, formation of non-woven cloth, non-woven warp weft not divided into cloth. Fiber clutter, radial zonal difference performance. Typical products: synthetic leather base cloth, acupuncture geotextile and so on.

是以涤纶、丙纶原料制造，经粗梳、精梳、预针刺，主针刺。中心加网布夹层，再经双道核理，气流成网针刺复合成布，后压滤布具有三维结构，经热定型，烧毛后，在表面最经化学油剂处理，使滤布外表光滑，微孔分布均匀，从表面看该产品的密度好，两面表面光洁和透气程度较好，在板框压缩机上过滤使用证明，可使用高强压力，过滤精度高达4微米以内，可根据用户需要提供丙纶和涤纶两种原料。

It is made of polyester and polypropylene fiber, through carding, combing, pre needling, main acupuncture. Center with mesh dissection, the double nucleus, airlaid acupuncture combined into cloth, then press cloth has a three-dimensional structure by heat setting, singeing, on the surface of the oil by chemical agent, make cloth smooth appearance, uniform pore distribution, from the surface density of the product is good, good sides smooth surface and air filtration, proof of use of the compressor can be used in the frame, high pressure, high filtration accuracy of less than 4 microns, can provide two kinds of raw materials of polypropylene and polyester according to user needs.
