Non woven bag is a kind of green product, which is produced from polypropylene. It is tough and durable, beautiful in shape, good in air permeability, reusable and widely used. Most of it is used in shopping bags, gift bags and advertising bags. What are its advantages and disadvantages?
advantage
1. Light weight: polypropylene resin is the main raw material, with a proportion of only 0.9, only three fifths of that of cotton. It is fluffy and feels good.
2. Softness: it is composed of fine fibers (2-3D) and formed by light spot hot melt bonding. The finished product has moderate softness and comfort.
3. Water drainage and air permeability: polypropylene chips do not absorb water, have zero moisture content, and the finished products have good water drainage. They are composed of 100 percent fibers, have porosity and good air permeability, and are easy to keep the cloth dry and easy to wash.
4. Non toxic and non irritating: the product is made of food grade raw materials conforming to FDA, does not contain other chemical components, has stable performance, is non-toxic, has no peculiar smell and does not stimulate the skin.
5. Antibacterial and chemical resistant agents: polypropylene is a chemical blunt substance, which is not eaten by insects, and can isolate the erosion of bacteria and insects in the liquid; Antibacterial, alkali corrosion, finished products will not affect the strength due to erosion.
6. Antibacterial property. The product has water pulling property and is not moldy. It can isolate the erosion of bacteria and insects in the liquid and is not moldy.
7. Good physical properties. It is made of polypropylene spinning, directly laid into a net and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength has no directionality and the longitudinal and transverse strength is similar.
shortcoming
1. Compared with textile cloth, the strength and durability are poor
2. It cannot be cleaned like other fabrics
3. The fibers are arranged in a certain direction, so they are easy to crack from a right angle
