Polypropylene BCF silk is a new type of differentiated fiber, suitable for the development of thick and thick decorative fabrics. The polypropylene BCF silk woven fabric produced by our factory has a rich and thick hand feeling, a rough appearance, and a rich luster.

Process design of polypropylene BCF silk products: polypropylene BCF silk has good fluffiness and is suitable for making sofas, Simmons bedspreads, car seat cushions and other masked decorative fabrics.

The carpet made of polypropylene BCF silk  has strong abrasion resistance, antistatic, its hand feel is better than wool, and it has excellent resilience and is not easy to pilling.

What are the reasons for the chromatic aberration of polypropylene BCF yarn?

Polypropylene BCF silk is widely used in carpet production. The minimal chromatic aberration of the filament will cause a large amount of chromatic aberration in the carpet and customer complaints. Thus, the chromatic aberration of the filament is the top factor affecting sales. Color difference usually refers to the difference in color that can be seen with the naked eye during production and use of the same batch of BCF filaments, which is specific to the difference between sections and sections, tube to tube, and even layer to layer color changes.

1. The quality of masterbatch. Since polypropylene fiber itself cannot be dyed, it is necessary to add color masterbatch in spinning to produce excellent yarn. However, the color difference caused by the quality of masterbatch is not rare. The color masterbatch itself is not uniform, and the existence of continuous cutting and clumping will now cause color difference. The measure taken is to frequently check the condition of the pelletizer, and the masterbatch produced is formed into slices of uniform size.

2. Temperature. The temperature of the polypropylene filament during the spinning process is also a major cause of the chromatic aberration. Because polypropylene itself has a low melting point, it is necessary to ensure that the spinning temperature is higher than 60° of the solubility of polypropylene itself in the spinning process to better produce colored yarn. However, the spinning temperature is very sensitive to color. This requires the technicians of Dr. Yarn to control the spinning temperature for different colored yarns.

3. Drafting deformation. People are skeptical that "drawing deformation" will cause chromatic aberration, which is generally considered impossible. However, it is very common from the customer's point of view. The measures taken are to ensure that the oil is applied at each position, the selection of the deformer and the generation of tension, all the consistency, which will effectively control the color difference.

4. The influence of stretching temperature. The drawing temperature is very important. The temperature should be controlled above the glass transition temperature of 10°-20°C. Too high temperature will dissolve and cause the thread to break. Too low temperature will also cause the filament end to be unsatisfactory and the color will be uneven. Studies have certified that the best stretching temperature is 130°.
