What are the factors affecting polypropylene BCF yarn?
1. The quality of masterbatch. Since polypropylene fiber itself cannot be dyed, it is necessary to add color masterbatch to produce excellent yarn during spinning. 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 polypropylene BCF yarn in 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. Excessive 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. According to research certification, it is better to control the stretching temperature at 130°.
There are many factors that affect polypropylene BCF yarn. The above four factors are the main factors affecting polypropylene BCF yarn. If you want to completely avoid chromatic aberration, you need to consider many small factors. This requires accumulating experience in practice and learning from failure. So as to achieve the final goal.
