Large chemical fiber: short fiber spun from PET chips or melt directly. Good color, large batch number, stable strength, few defects, and good spinnability; Sinochem: Spun with PET chips or with PET back material. The price and quality are between Dahua and Xiaohua (mainly some spinning mills are used to blend with Dahua to enhance competitiveness); small chemical fiber: use PET back to spin. The price and quality are uneven, and it is suitable for exporting to some markets and fields where quality requirements are not too high (such as fillers, etc.).
