Summary
This article introduces the excellent characteristics of non-woven fabrics and non-woven environmental protection bags. Through experimental comparison, it is found that non-woven environmental protection bags are better than ordinary plastic bags in terms of durability and degradation performance, thereby reducing the cost of ordinary plastic bags. The white pollution has enhanced people’s environmental awareness.
As people's awareness of environmental protection has increased, the 'white pollution' caused by plastic bags has attracted the attention of various countries. Countries around the world have formulated regulations for shopping plastic bags to restrict or prohibit their use. Various relevant mandatory policies and regulations in my country have been promulgated one after another. From June 1, 2008, all major supermarkets across the country have stopped providing plastic shopping bags for free [1]. How to develop alternative products that are conducive to environmental protection and generally accepted by low-income groups has become a research hotspot in solving the problem of plastic bags. Among several alternatives, non-woven shopping bags are considered the best alternatives to plastic bags due to their short process flow, high output, rapid variety, wide raw material sources, long service life, and degradability. . This article mainly discusses the bursting strength and abrasion resistance of non-woven eco-friendly shopping bags, in order to encourage people to use eco-friendly bags to protect the earth and humans.
1. Introduction of non-woven fabric
1.1 The concept of non-woven fabrics
The production of non-woven fabric breaks through the conventional textile processing principle. It is a textile material that does not require spinning and weaving. As long as the short fibers or filaments for textile are oriented or randomly arranged to form a web structure , And then use mechanical, thermal bonding or chemical methods to strengthen the shape.
1.2 The main properties of non-woven fabrics
Non-woven fabric is composed of filaments laid on each other into a net, with high porosity, good light permeability, strong moisture permeability, high air permeability, non-toxic and non-irritating; in addition, it can be recycled more Reusable, degradable or recyclable, and has the advantages of light, soft, elastic, corrosion-resistant, and washable. Non-woven fabrics have fast production speed, short process flow, low cost, high output, wide raw material sources and uses, and rich colors.
1.3 The production process of non-woven fabrics
According to different processing technologies, non-woven fabrics can be divided into production processes: needle-punched non-woven fabrics, spunlace non-woven fabrics, wet-laid non-woven fabrics, stitched non-woven fabrics, heat-bonded non-woven fabrics, and melt-blown non-woven fabrics. Woven fabrics, spunbond non-woven fabrics, pulp air-laid non-woven fabrics, etc. Among them, non-woven eco-friendly bags are mostly heat-sealed non-woven fabrics.
2. Characteristics of non-woven shopping bags
The plastic bags commonly used in daily life are non-degradable, or the degradation period can take decades or even hundreds of years. Due to the non-degradable properties of ordinary plastic bags, soil and groundwater are contaminated. In addition, a complete plastic bag can only be used to store garbage or throw away after the items are carried from the supermarket to the residence. There is still a serious waste problem.
The environmentally friendly shopping bags are safe and hygienic during use, and can be recycled many times; the used shopping bags can be degraded, or can be recycled and reused.
3. Application prospects
With the rapid development of my country's economy and the continuous improvement of people's quality of life, people's awareness of environmental protection is increasing day by day. Non-woven environmental protection bags produced by using natural fibers or biodegradable fibers can meet the requirements of environmental protection and saving. If polyamide fiber is added in the production of non-woven fabrics, it can make it have better load-bearing capacity and durability. In addition, non-woven bags that have been processed after water and oil repellency, antibacterial, and easy decontamination are not easily stained by water and oil, and they also have antibacterial properties, and it is convenient to clean when necessary. The shopping bag has a small volume after being folded, convenient to carry and store, and meets the requirements of repeated use. With the maturity of non-woven processing technology and the decline of processing costs, non-woven environmental protection bags will certainly have a good application prospect.
