PP spunbond non-woven fabric production technology

Fujian Plastic Industry Co., Ltd. has a series of complete and sophisticated non-woven fabric production equipment. The PP spunbond non-woven fabric produced by it has good high temperature resistance, low temperature resistance, light resistance and water resistance. The following is a specific introduction to PP spunbond Non-woven fabric. PP spunbond non-woven fabrics are light in weight and use polypropylene resin as the main raw material. The specific gravity is only 0.9, only three-fifths of cotton. It is fluffy and feels good. Soft: It is composed of fine fibers (2-3D) and is formed by light-point hot-melt bonding. The finished product is moderately soft and comfortable. Water repellent and breathable: Polypropylene slices do not absorb water, have zero water content, and have good water repellency. The fiber is composed of porous and air-permeable. It is easy to keep the cloth dry and easy to wash. No irritation: The product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, no peculiar smell, and does not irritate the skin. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, not moth-eaten, and can isolate the corrosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and the strength of the finished product will not be affected by erosion. Antibacterial. The product is water-repellent, not moldy, and can isolate the bacteria and insects in the liquid from erosion, and is not moldy. Good physical properties, it is made of polypropylene spun yarn directly spread into a net and thermally bonded. The product strength is better than ordinary staple fiber products, the strength is non-directional, and the vertical and horizontal strengths are similar.　Structural principle of the switchable needle punching machine Needle punching mechanism: The needle is installed on a flat plate that reciprocates with a fixed stroke, and the needle is sandwiched between two flat plates with a fiber web that moves at a certain speed for up and down puncture movement. The two plates are drilled with holes at the same position and correspond to the needle implant position on the needle plate. When the fiber web is fed into the needle punching machine, the fiber web is very fluffy, and the cohesion of the fiber and the fiber is poor, and there is almost no strength. When thousands of barbed needles penetrate the fiber web, the hooks on the needles carry part of the fibers in the web with the needles through the fiber web and compress the web. When the needles penetrate a certain depth, they rise , Due to the forward direction of the hooks, the fibers with the needles are separated and left in the fiber web, so that the compressed fiber web does not return to its original shape and finally becomes a non-woven fabric. The needle plate needles designed and manufactured are arranged regularly, and the needle punch marks of the produced non-woven fabrics are also orderly. Now it has developed into random needle punching, and the needle holes of the non-woven fabric have a uniform and beautiful surface. Polyester filament spunbond production line features: the nozzle draws the air flow to make the filament speed up to 5000 m/min, and the single filament strength is higher: after the filament is formed into a net, the web is random, but the microstructure shows that the filament is in a continuous state. Because of these characteristics, the needle punching machine used in the production of filament non-woven fabrics is determined. Compared with the short fiber cloth, the felting needle makes the fiber web cloth more stressed and easy to break the needle. Due to the short fiber non-woven fabric, both ends of the fiber can be stretched freely, and the needle load is lighter. Another feature of the production line is that the filament non-woven fabric production line is continuous production from chip feeding to product winding. The short fiber non-woven fabric can be stopped at any time to change needles, and the filament non-woven fabric production shutdown will generate a lot of waste. Therefore, the filament spunbond method is easy to break the needle, and it is not suitable to stop. The design of the needling machine proposes the need for the needling depth process characteristics. The need for the needling machine is switchable. The working principle of the needling machine is relative to the production line. The production line continues to produce products when the needle is changed. Each needling machine is installed with two sets of needle beam needle plates, sharing a set of stripping and supporting net plates. When one set of needle beams is working, the other set of needle beams is used as a spare. When the working set needs to change the needles, the spare set is started and the frequency reaches the production requirements, the stripping net board and the net board are moved up and down at the same time to switch to the needle penetration depth required by the process. After the spare needle beam works normally, the original working needle beam is stopped. Change the needle. The basic structure of the acupuncture machine includes a frame, a crankcase, upper and lower opposed needle beams, a net stripping board, a net support board, a cloth conveying and pulling mechanism, a net board lifting device, and an electrical control part. Fujian Plastic Industry Co., Ltd. adheres to the business philosophy of meeting the individual needs of customers, and has won the trust of customers by learning the world's advanced production technology level, continuous innovation of independent products, reliable quality assurance and perfect service system.
