The polypropylene fiber testing project mainly focuses on the detection of physical and chemical performance indicators. Bain Testing recommends physical and chemical performance testing projects mainly including density, linear density and deviation rate, coefficient of variation, fracture strength and coefficient of variation, elongation at break and coefficient of variation, solvent residue rate, boiling water shrinkage rate, oil content, cylinder weight, double length fiber content, curl rate, ash content, and other indicators, Of course, some composite short fibers may need to be tested for electrical resistance, such as specific resistance indicators, hygiene performance indicators such as the total number of bacterial colonies and fungal colonies. In addition, the determination of polypropylene fiber content is also a common testing item
