The new spunbond technology developed by Kobe Steel Co., Ltd. can be used for spunbonding, meltblown nonwovens and SMS, and can process raw materials such as PP, PET, PA and PLA. The company's twin-screw extruder is especially suitable for the melting of PET. The density of the web is up to 150g/m2, the production speed is 500m/min, and the ultra-fine fiber of 0.5dtex can be processed. The product is soft, strong and uniform. Good sex.
Kobe Steel's spunbond process has the ability to process a wide range of polymers. It can be made into fine denier, fine denier and ultrafine denier fibers. It has a high spinning speed and good product uniformity. It can produce PP and on the same production line. PET spunbond products. The device directly feeds the wet, non-crystalline polymer chips into the extruder, eliminating the need for crystallization equipment or drying equipment for polyester chips. The extruder has good polymer mixing properties, all using electric heating, high precision and wide temperature control, a wide enough spinning crossbar and a spinneret with 8 built-in spinning pumps. A stretching nozzle of sufficient width can change the direction and speed of the fiber at will.
Kobe Steel's twin-screw extruder has the ability to degas and dehumidify, and the oligomers contained in the slicing can be emptied and removed in the screw sleeve. This equipment is the world's deepest screw-spinning twin-screw extruder, which can more effectively mix materials and reduce the shear rate. When the polymer changes, it can shorten the material conversion (such as from PP to PET). The time required to significantly reduce the amount of transition material; the machine has the unique flexibility to squeeze a variety of polymers, such as PET, PP, PA, CoPET and recycled PET, and without the need to replace the screw in production, and conventional Compared with the single-screw extruder, it has the advantages of high efficiency, high output, uniform melting and low temperature. The twin-screw extruder has a ventilation device, and various additives can be added and mixed in the extruder when processing PP, and the spinning operation can be performed well. The twin-screw extruder has better spinning performance and better mixing performance than the single-screw extruder.
