bonded knit fabric characteristics -The characteristics of non-woven fabrics
The characteristics of non-woven fabrics: 1. Light weight: Polypropylene resin as the main raw material for production, the proportion of only 0.9, only three-fifths of cotton, with a fluffy, feel good. 2. Soft: Made of fine fibers (2-3D) Light-point hot-melt adhesive. The finished product is soft and comfortable. 3. Water repellent, breathable: Polypropylene chips do not absorb water, moisture content is zero, the finished product is water-repellent, composed of 100% fiber with porosity, good air permeability, easy to keep the fabric dry and easy to wash. 4. Non-toxic, non-irritant: The product is produced in accordance with the FDA food grade raw materials, free of other chemical components, stable performance, non-toxic, no odor, does not irritate the skin.

5. Anti-bacterial and anti-chemical agents: Polypropylene is a chemically inert material, not insects, and can isolate bacteria and insects in the presence of liquid erosion; antibacterial, alkaline corrosion, the finished product will not affect the strength due to erosion. 6, antibacterial. The product is water-pulling, not mildewed, and can isolate the bacteria and insects in the liquid. 7, good physical properties. The direct spinning of polypropylene spinning is made by heat-bonding. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional and the strength in both vertical and horizontal directions is similar. 8, in terms of environmental protection. The raw material of most of the non-woven fabrics currently used is polypropylene, and the raw material of plastic bags is polyethylene. Although the two materials have similar names, their chemical structures are quite different. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade. Therefore, the plastic bag needs 300 years to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken and can be effectively degraded. , And in the non-toxic form into the next environmental cycle, one can completely decompose within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the environmental pollution after disposal is only 10% of the plastic bags.
