UD nonwovens manufacturers talk about what nonwovens are
What is nonwovens? Why is it called weft free cloth? What industry does nonwovens belong to? The high-performance fiber "UD" non weft cloth is made of ultra-high strength and high modulus polyethylene fiber as the base material, evenly laid with advanced high-tech equipment, impregnated with high-strength elastomer resin, glued and bonded with film, and then 0 ° / 90 º Bi orthogonal composite lamination. The product has excellent properties such as soft feel, low density, wear resistance, impact resistance and strong cutting toughness. The product is widely used in soft bulletproof clothing, light bulletproof helmets, light bulletproof armor plates, stab proof and cutting proof clothing linings and special public anti riot facilities. It is a bulletproof material with high strength and light specific gravity in the world.

The utility model relates to a continuous weft free cloth preparation equipment and process, which belongs to the technical field of machinery. The equipment is successively provided with a wire laying equipment, a release paper unwinding equipment, a multi roll hot pressing equipment, a release paper unwinding equipment, an isolation film unwinding equipment, a cutting device and a winding device from front to back, which is characterized in that the hot pressing equipment is provided with a pressing hot roll and a pressing cold roll; A release paper stripping device is arranged on the winding support of the release paper winding equipment; The isolation film unwinding equipment comprises an isolation film unwinding box body, the front of the box body is provided with a transition roll, and the middle of the box body is symmetrically provided with a pressing roll up and down; A rotating shaft is symmetrically arranged up and down between the supports on both sides of the cutting device, and a preset number of toothless circular saw blades are arranged on the rotating shaft. The beneficial effect of the invention is that the equipment and process can effectively and continuously produce unidirectional weft free cloth, with neat cutting and winding, convenient operation, low cost, effectively preventing fiber breakage and distortion, and improving the production quality of weft free cloth.
