[What are the methods to reduce the polypropylene BCF yarn?]
Release date:[2019/7/4] Is reading[741]次

According to the actual production, the causes and control measures of the polypropylene BCF yarn are discussed. By optimizing the original science and adjusting the process to keep the equipment in good condition, the wool is obviously reduced. In the production process of polypropylene BCF yarn, the filaments in the tow are broken and the filaments are formed due to uneven tensile properties of the tow, bubbles in the monofilament, excessive stretching ratio or insufficient oiling.


Wool is one of the factors affecting the quality of polypropylene BCF yarn. It not only affects the appearance quality of the fiber, but also affects the physical and mechanical properties of the fiber. If there are too many filaments, the skein will appear during the processing of the carpet, and the tow will not break through the pinhole. Based on the actual production, we have done a lot of experiments on the introduction of polypropylene BCF yarn production equipment to explore ways to reduce the polypropylene BCF yarn.


in conclusion:

1) Selecting polypropylene chips with high isotacticity and low moisture and ash content is beneficial for reducing wool.


2) Keep the melt rheology uniformity of the spinning box, select the lower spinning temperature, and choose the appropriate side blowing temperature, wind speed and suitable stretching process to reduce the filament.


3) Keep the equipment clean and have a positive effect on reducing the hair.
