The characteristics of non-woven sheets, the advantages of non-woven sheets, people who have been to the hospital know that in the hospital some inspection or rest of the bed, will be covered with a thin layer of sheets that look like paper, basically, it is disposable. We call this kind of bed sheet non-woven bed sheet. Non-woven bed sheet is generally used very little in the home. Features of non-woven sheets: non-woven sheets have no sewing thread, cutting and sewing are very convenient, and they are light and easy to shape; Non-woven sheet is a fabric formed without spinning and weaving. It only orders or randomly arranges textile staple fibers or filaments to form a fiber mesh structure, then it is reinforced by mechanical, thermal or chemical methods; Non-woven sheets are not interwoven and knotted by one yarn, but are bonded directly to each other by physical means. Therefore, when you get the stick in your clothes, you will find that you can't draw a thread. Non-woven fabric breaks through the traditional textile principle and has the characteristics of short process flow, fast production rate, high output, low cost, wide use and many sources of raw materials. Advantages of non-woven sheets: 1. Light weight: polypropylene resin is the main raw material for production, with a specific gravity of only 0. 9, only cotton non-woven fabric finished product 3/5, fluffy, feel good. 2, soft: composed of fine fibers (2-3D) Light-shaped hot melt bonding, non-woven sheets are moderately soft and comfortable. 3. Water allocation and ventilation: polypropylene slices do not absorb water, have zero water content, have good water allocation for finished products, have porous properties composed of 100% fibers, have good air permeability, and are easy to keep the cloth surface dry and easy to wash. 4, non-toxic, non-irritating: The product is produced in accordance with FDA food grade raw materials, does not contain other chemical components, stable performance, non-toxic, no smell, does not irritate the skin. 5, antibacterial, anti-chemical agents: polypropylene is a chemical blunt substance, no insects, and can isolate the erosion of bacteria and insects in the liquid; Antibacterial, alkali corrosion and finished products do not affect their strength due to erosion. 6, antibacterial: non-woven sheets are water-drawn, not moldy, and can isolate the erosion of bacteria and insects in the liquid, no mold. 7. Good physical properties: it is directly made of polypropylene spinning into mesh heat bonding. The strength of the product is better than that of General staple fiber products, the strength is non-directional, and the vertical and horizontal strength is similar. 8. In terms of environmental protection: the raw material of most non-woven sheets used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, they are far from each other in chemical structure. The chemical molecular structure of Polyethylene has considerable stability and is extremely difficult to degrade, so it will take 300 years for plastic bags to be decomposed; However, the chemical structure of polypropylene is not firm, and the molecular chain can easily break, thus effectively degrading and entering the next environmental cycle in a non-toxic form, A non-woven shopping bag can be completely decomposed in 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the pollution to the environment after disposal is only 10% of that of plastic bags.
