The carpet made of polypropylene BCF is extremely strong, anti-static, its hand feels like wool, and the elasticity is also excellent, not easy to start. Where is the polypropylene BCF?

The polypropylene BCF is refined by the polypropylene raw material, and the filament obtained by polymerization, in recent years, due to the characteristics of the strong fibers in the polymerization of the polypropylene BCF, the sales supply in the market is in short supply, and the factory should press time. High quality completion.

What are the reasons for the color difference of polypropylene BCF?

The polypropylene BCF is widely used in carpet production. The color difference of filament is poorly caused by a large number of colors of color differences and customers, thereby forming long-filament differences and other factors affecting sales. The color difference is generally referred to in the same batch of BCF filaments, production and use, which can be seen in the naked eye, specifically to the difference between the sections, the cartridge, and even the color change of the layer and the layer.

Quality of color masterbatch. Since the polypropylene itself cannot be dyed, the spinning is appropriately added to the color masterbatch to produce a good yarn. However, the color difference caused by the quality of color masterbatch is not a small number. The color master is uneven, and there is a knife, and it will now cause color difference. The measures taken are frequently inspected the particularging machine, and it is a size uniform slice of production.

2. Temperature. The temperature in the spinning process is also a major cause of color difference during the spinning process. Because the polypropylene itself has a high melting point, it is necessary to ensure that the spinning temperature is 60 ° higher than the solubility of the polypropylene itself during the spinning process. However, since the spinning temperature is very sensitive to the color. This requires a doctors of the yarn to control the spinning temperature for colorless yarns of different colors.

3. Drop the deformation. People will lead to color differences in "drafting deformation", and their attitudes are generally considered to be impossible. However, it is common from the customer to see this. The measure is to ensure that the oil, the selection and tension of the deformer, all consistency, which will effectively control the color difference.

4. The effect of tensile temperature. Tropic temperature is very important. The temperature should be controlled in the glass transition temperature of 10 degrees - 20 degrees or more. The temperature is too high to dissolve cause the wire to break. The temperature is too low, which will cause the filament to do not disagree with the color. The study is certified, the tensile temperature is controlled in 130 °.
