What are the performance indicators of polypropylene BCF yarn?

Polypropylene BCF yarn is treated by putting the yarn in steam or hot air or boiling water. At this time, the fiber with high shrinkage produces greater shrinkage and is located in the center of the yarn. The low shrinkage fiber mixed together is Extruded to form a loop on the surface of the yarn, thereby obtaining a fluffy, full, elastic BCF yarn.

Polypropylene BCF yarn characteristics: it combines the high strength of continuous long fibers and the bulkiness of short fibers, with the characteristics of high temperature resistance, friction resistance, and corrosion resistance.

Performance index of polypropylene BCF yarn: The grey cloth woven from polypropylene BCF yarn is generally finished by dyeing, raising (single or double-sided), etc. The fabric requires soft, fluffy, elastic and uniform dyeing. Therefore, the bulkiness of bulked yarn, the specifications of raw materials, and the uniformity of mixing are its main performance indicators.
