Polypropylene stretch filament purchasing guide: Easy way to distinguish the quality of the filament! 

1. Observe the appearance to screen out basic quality issues

High-quality polypropylene elastic yarn has a clean and tidy appearance, with uniform and smooth yarn strands, and a unified overall color. There are no obvious color differences, stains, or impurities. Carefully inspect the yarn spools, and the formation is tight and regular, with uniform thread arrangement, without loose edges, overlapping threads, or disordered threads. 

II. Feel the texture and test the elasticity to determine the core performance

The texture is an intuitive way to distinguish the quality of polypropylene elastic filament. High-quality filament has a soft and smooth texture, with natural rebound when held, and can smoothly return to its original shape after stretching. The elasticity is durable and stable, and it does not easily loosen or deform after repeated stretching. Poor-quality filament has a harder, dry and rough texture, with sluggish rebound and incomplete recovery after stretching. Over time, it is prone to elasticity loss, resulting in loose and deformed finished products with significantly reduced service life. At the same time, you can simply compare the filament from the same batch. The quality products have good batch consistency and no significant performance differences. 

When purchasing polypropylene elastic yarn, there is no need to blindly choose low-priced products. Instead, prioritize selecting raw materials with uniform appearance, regular shape, stable rebound, and stable batches. These materials should be compatible with one's own weaving process, which can not only reduce production losses but also ensure the stability of the finished product quality.
