Light weight: The main raw material is polypropylene resin, the specific gravity is only 0.9, only three-fifths of cotton, with fluffiness and good hand feeling. Soft: Made up of fine fibers (2-3D) with light dotted hot-melt bonding. The finished product is moderately soft and has a comfortable feel. Water repellence and breathability: polypropylene slices do not absorb water, and the water content is zero, so the finished product has good water repellence, and is composed of 100% fibers with porosity and good breathability, which makes it easy to keep the fabric dry and washable. Non-toxic and non-irritating: The product is produced with FDA food-grade raw materials and does not contain other chemical ingredients, with stable performance, non-toxic, odorless and non-irritating to the skin. Antibacterial and chemical resistant: polypropylene is a chemically blunt substance, not insects, and can isolate the presence of bacteria and insects within the liquid erosion; antibacterial, alkali corrosion, finished products do not affect the strength due to erosion. Good physical properties: made of polypropylene spun yarn directly laid into a network of hot bonding, the strength of the product is better than the general staple fiber products, strength is not directional, longitudinal and horizontal strength is similar.
