PP non-woven fabrics used in the raw material is polypropylene (PP) olefins, in the production before the first need to crush the PP raw material fusion process, in this process, the resulting fine fabric dust, will cause harm to the human body, so the first is to Pay attention to the health of the workers.
PP non-woven fabrics are high-grade insulation materials in the insulation products, production as far as possible to avoid all aspects of the rejection rate, PP Nonwoven Fabric improve product success rate is to win the fundamental market, it must strengthen the regular maintenance of production equipment, so as not to affect the product quality.
PP nonwovens is widely used, not only because of the unique advantages of the product itself, but also because of its process is also in other processes are more dominant, PP Nonwoven Fabric from the production process to the product itself, have been more than the same Market sales of products.
PP non-woven characteristics
Nonwovens break through the traditional textile principles, and has a short process, PP Nonwoven Fabric production speed, high yield, low cost, wide use, raw materials and more features.
The type of non-woven non-woven fabrics according to the different production processes can be divided into: 1, Spunlaced non-woven fabrics: the high-pressure micro-jet is sprayed onto one or more layers of fiber network, so that the fibers tangled together, so So that the network can be reinforced with a certain strength. 2, heat-bonded non-woven fabrics: refers to the fiber in the fiber or powder-like hot-melt adhesive reinforcement materials, fiber and then heated by heating and cooling into a cloth. 3, pulp air into non-woven fabrics: PP Nonwoven Fabric also known as clean paper, dry paper non-woven fabrics. It is the use of air-laid technology to open the wood pulp fiber board into a single fiber state, and then use the air flow method to agglutinate the fiber into the curtain, the fiber mesh and then reinforce the cloth. 4, wet non-woven fabric: is placed in the water medium in the fiber raw materials open into a single fiber, while mixing different fiber raw materials, made of fiber suspension pulp, PP Nonwoven Fabric suspended pulp transported to the network, the fiber in the wet Into the network and then reinforce the cloth. 5, spunbond non-woven fabrics: the polymer has been extruded, stretching and the formation of continuous filament, the filament laying into a net, the fiber mesh and then through their own bonding, thermal bonding, chemical bonding or mechanical reinforcement Method to make the web into a nonwoven fabric. 6, meltblown non-woven fabrics: the process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into the network --- reinforced into cloth. 7, acupuncture non-woven fabric: a dry non-woven fabric, acupuncture non-woven fabric is the use of puncture needle puncture, the fluffy fiber reinforced into a cloth. 8, sewing non-woven fabric: is a dry non-woven fabric, sewing method is the use of warp-knitted coil structure of the network, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or The combination of them is reinforced to form a nonwoven fabric.
