Introduction: non-woven fabrics, also known as non-woven fabrics, this material is widely used because of the environmental protection and convenience, it is a lot of material components, you can distinguish a variety of non-woven styles, used for disposable products is very suitable, because of its non-toxic and tasteless, relatively inexpensive, can be discarded after the use of the replacement, for the user of the hygiene and cleanliness, for the use of the material is also very Environmentally friendly. This colorful and colorful non-woven sheets, we can see in hospitals and other public **** places, so what are the advantages and disadvantages of using non-woven sheets, and what are the characteristics of the non-woven sheets themselves?
Nonwoven sheet material characteristics
1. Lightweight: polypropylene resin as the main raw material, specific gravity is only 0.9, only three-fifths of cotton, with fluffy, feel good.
2. Soft: composed of fine fibers (2-3D) light point-like hot melt bonding molding. The finished product is moderately soft and comfortable.
3. Water-repellent and breathable: Polypropylene slices do not absorb water, water content is zero, the finished product has good water-repellent properties, composed of 100% fibers with porous, breathable, easy to keep the cloth dry, easy to wash.
4. Non-toxic, non-irritant: the product is produced with FDA food-grade raw materials, does not contain other chemical components, stable performance, non-toxic, no odor, does not irritate the skin.
5. Antibacterial, anti-chemical agents: polypropylene is a chemical passive substance, not insect, and can isolate the presence of bacteria and insects within the liquid erosion; antimicrobial, alkali corrosion, the finished product does not affect the strength due to erosion.
6. Antibacterial. Products with water pulling, not moldy, and can isolate the existence of bacteria and insects in the liquid erosion, not moldy.
7. Good physical properties. Spun by the polypropylene directly laid into a network of thermal bonding, product strength is better than the general short-fiber products, strength is not directional, longitudinal and transverse strength is similar.
8. In terms of environmental protection, most of the current use of non-woven raw materials is polypropylene, while the raw material of the plastic bag is polyethylene, the two substances, although the name is similar, but in the chemical structure is very different. Polyethylene's chemical molecular structure has a fairly strong stability, extremely difficult to degrade, so plastic bags need 300 years to decompose; and polypropylene's chemical structure is not strong, the molecular chain can be easily broken, which can be effectively degraded, and in the non-toxic form to enter the next step of the environmental cycle, a non-woven shopping bags in 90 days can be completely decomposed. And non-woven shopping bags can be reused more than 10 times, after the disposal of the environmental pollution degree is only 10% of the plastic bag.
Advantages of using non-woven sheets
Non-woven sheets are disposable bedding, convenient and hygienic. If necessary, you can also add antimicrobial masterbatch in the production process of non-woven fabrics, to achieve antibacterial effect, safer and more reliable to use; you can also add flame retardant masterbatch in the production process of non-woven fabrics, to achieve flame retardant effect. And the use of cloth sheets need to be replaced, cleaning, waste a lot of human and material resources.
Disadvantages of non-woven sheets
1)Compare with the textile strength and durability is poor
2)Can not be cleaned like other fabrics
3)Fiber arranged in a certain direction, so it is easy to split from the direction of the right angle and so on. Therefore, recent improvements in production methods have been focused on preventing splitting.
After a small introduction, I believe you have some in-depth understanding of the characteristics of non-woven sheets, for the use of non-woven sheets advantages and disadvantages are also known. In fact, although the non-woven sheet is disposable, but this non-woven environmental protection material is very environmentally friendly, will not bring harm to the environment, placed in the outdoors can be naturally decomposed, so the general non-woven sheet also has a service life, so do not need to worry about how to deal with its replacement. If you have this demand, you can consider the hygiene and environmental protection of non-woven sheets instead of traditional sheets.
