Optimization strategy of polypropylene BCF yarn
1. Raw material optimization
Select high-quality polypropylene slicing: Polypropylene slicing is the main raw material for the production of polypropylene BCF yarn, and its quality directly affects the performance of the yarn. Polypropylene slices with high isotropy, low ash and water content should be selected to improve the mechanical properties of products and reduce impurities in the production process.
Strict screening of masterbatches: The quality of the masterbatch is critical to the color uniformity and stability of the yarn. Appearance inspection and trial spinning test should be carried out to ensure the mixing uniformity and particle size uniformity of the masterbatch.
2. Process optimization
Adjusting spinning temperature: Spinning temperature has an important effect on the rheological properties of polypropylene melt. The spinning temperature should be adjusted according to the raw material characteristics and product requirements to ensure the quality of the primary fiber.
Optimization of bulking process: bulking temperature and bulking pressure are the key factors affecting the bulking degree of polypropylene BCF yarn. The optimum swelling temperature and pressure should be determined by test to obtain the ideal swelling effect.
Improved oiling device: nozzle type double-sided oiling device is used to ensure uniform oil on the tow, reduce oil pollution and the generation of hair.
Precise control of the metering system: The stability of the metering system is crucial for the generation of color differences. The metering system should be calibrated regularly to ensure that the ratio of masterbatch and slice is accurate and to avoid chromatic aberrations and filaments.
3. Equipment optimization
Introduction of advanced production equipment: the use of international advanced spinning equipment, such as Switzerland Rieter, Germany Neumag and other companies spinning machine, in order to improve production efficiency and product quality.
Upgrade existing equipment: Upgrade the existing equipment, such as increasing the mixing roller, changing the position of the wire cutter, etc., to optimize the production process and improve the uniformity and stability of the product.
