fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form new fiber products with soft, air-permeable and flat structure through various web forming methods and consolidation technologies. Compared with traditional plastic bags, non-woven bags have the following advantages: non-woven bags are inexpensive and good-quality, environmentally friendly and practical, widely used, and have prominent advertising positions. It is suitable for all kinds of business activities and exhibitions, and is an ideal advertising promotion gift for enterprises and institutions.
The raw material of the non-woven bag is polypropylene, while the raw material of the plastic bag is polyethylene. Although the two substances have similar names, their chemical structures are quite different. The chemical molecular structure of polyethylene is very stable and difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded. And enter the next environmental cycle in a non-toxic form, a non-woven bag can be decomposed within 90 days.
Non-woven fabric is a product that does not require a weaving process and is made into a non-cloth-like product, also called non-woven fabric. Because it only needs to oriented or randomly support the textile short fibers or filaments to form a fiber network structure, and then use mechanical, thermal bonding or chemical methods to strengthen it. Most non-woven bags are made of spunbonded non-woven fabrics.
To put it simply, non-woven fabrics are not interwoven and braided one by one, but the fibers are directly bonded together by physical methods. Therefore, when you get the sticky weight in your clothes At that time, you will find that it is impossible to draw out the thread ends. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials.
Laminated non-woven bag, the product adopts the casting method, the compound is firm, it is not glued during the compounding process, it has a soft hand, no plastic feeling, and no skin irritation. It is suitable for disposable medical sheets, bed sheets, surgical gowns, Isolation clothing, protective clothing, shoe covers, and other health protection products; bags made of this kind of cloth are called laminated non-woven bags.
