Polypropylene is extremely soft and lightweight. It is also fluffy, skin friendly, and has good elasticity. It is different from ordinary chemical fibers and has a second skin effect that is close to nature. It will not cause sensitive irritation to the skin. Compared to the commonly used fibers in clothing, we rank among the top with a specific gravity of 0.91, which is the lightest of all fibers.

The commonly used fiber specific gravity is as follows (g/till):

Under the same specifications and weight of fiber filaments, the weight is 50% lighter than cotton, 35% lighter than polyester, and 20% lighter than nylon. Therefore, it has a high cost performance.
