The production of polypropylene filament is nothing more than conventional spinning speed and high-speed spinning speed, so how do they compare? In the spinning process, polypropylene can't use high-speed spinning system as easily as polyester. The main reason is that the cooling rate of polypropylene is too slow and the curing rate is limited.

In fact, the spinning method is a few kinds. The spinning method produces super fine polypropylene fiber, which is a good method for spinning the spinning of polypropylene fiber. This method avoids all the problems caused by polypropylene cooling and makes the primary spinning smooth. One drawback, however, is that the devices needed for spinning are two, such as extruders and spinning boxes. If the problem of filaments is solved, then the stripping method is the best way to produce the polypropylene filament. The definition of high strength polypropylene filament is at 0.7 dtex polypropylene monofilament, the monofilament is explained in the narrower molecular content in spinning process is easy to implement, technology mainly focuses on in the article to forming, stretching and roll form three aspects.

With ordinary polypropylene production to should notice to filament number more than low, prone to wool yarn, spinning process to overcome the major operating reasonable equipment and carefully research can have reasonable parameters to solve. The production of polypropylene high strength silk has the advanced technology feasibility, the quality of the quality of the yarn has made Shanghai Keats popular with the majority of customers.
