What Is Non Woven Reusable Bags?

Abstract

This paper introduces the excellent characteristics of non-woven fabrics and non-woven eco-friendly bags. Through experimental comparison, it is known that non-woven eco-friendly bags are superior to ordinary plastic bags in terms of durability and degradation performance. Thus, the white pollution caused by ordinary plastic bags is reduced, and people's awareness of environmental protection is enhanced.

With the enhancement of people's awareness of environmental protection, 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 mandatory policies and regulations related to China have been promulgated one after another. From June 1, 2008, the provision of free plastic shopping bags in major supermarkets across the country has been suspended [1]. How to carry out the development of alternative products that are beneficial to environmental protection and generally accepted by low-income groups has become a research hotspot to solve the problem of plastic bags. Among several substitutes, non-woven eco-friendly shopping bags are considered to be the best substitutes for plastic bags because of their short technological process, high output, fast variety changes, wide source of raw materials, long service life, and degradability. . This article mainly discusses the bursting strength and wear resistance of non-woven eco-friendly shopping bags, in order to advocate the use of eco-friendly bags, protect the earth and protect human beings.

1. Introduction of non-woven fabrics

1.1 The concept of non-woven fabrics

The production of non-woven fabrics breaks through the conventional textile processing principle and is a kind of non-woven fabrics. Textile materials formed without spinning and weaving can be formed by orienting or randomly arranging short fibers or filaments for textiles to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods.

1.2 Main properties of non-woven fabrics

Non-woven fabrics are made of filaments laid on each other to form a network, with high porosity, good light transmittance and strong moisture permeability , High air permeability, non-toxic and non-irritating characteristics; in addition, it can be recycled many times, degradable or recycled, and the texture is light, soft, elastic, corrosion-resistant, washable and so on. The production speed of non-woven fabrics is fast, the process flow is short, the cost is low, the output is high, the raw material sources and uses are wide, and the colors are rich.

1.3 Production process of non-woven fabrics

The production process of non-woven fabrics can be divided into: needle-punched non-woven fabrics, spunlace non-woven fabrics, wet-laid non-woven fabrics according to different processing technologies Non-woven fabrics, stitch-bonded non-woven fabrics, heat-bonded non-woven fabrics, melt-blown non-woven fabrics, spunbond non-woven fabrics, pulp air-laid non-woven fabrics, etc. Among them, non-woven environmental protection bags are mostly heat-sealed non-woven fabrics.

2. Characteristics of non-woven shopping bags

The plastic bags commonly used in daily life are not degradable, or the degradation years will take decades or even a few years. century. Due to the non-degradable properties of ordinary plastic bags, soil and groundwater are polluted. In addition, a complete plastic bag can only be used for garbage or directly thrown away after carrying the items from the supermarket to the residence, and 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 shopping bags after use can be degraded, or can be recycled and reused.

3. Application Prospects

With the rapid development of China's economy and the continuous improvement of people's quality of life, people's awareness of environmental protection is increasing. The requirements of environmental protection and saving can be achieved by using non-woven environmental protection bags produced from natural fibers or degradable fibers. If polyamide fibers are added to the production of nonwovens, they can have better load-bearing capacity and durability. In addition, the non-woven bags that have been processed by water and oil repellent, antibacterial and easy decontamination are not easy to be stained by water and oil, and also have antibacterial properties, and it is more convenient to clean when necessary. After being folded and folded, the shopping bag is small in size, convenient to carry and store, and meets the requirements of repeated use. With the maturity of non-woven processing technology and the reduction of processing costs, non-woven environmental protection bags will have good application prospects.

Uneven thickness of non-woven fabrics may be caused by the following points under the same processing conditions:

(1) The uneven blending of low-melting fibers and conventional fibers: different fibers have different holdings Cohesion, generally speaking, low melting point fibers have greater cohesion than conventional fibers, and are not easy to disperse. For example, Japan 4080, South Korea 4080, South Asia 4080 or Far East 4080 have different cohesion. The melting point fibers are unevenly dispersed, and the part with less low melting point fiber content cannot form a sufficient network structure, and the non-woven fabric is thinner, which is thicker than the part with more low melting point fiber content.

(2) Incomplete melting of low melting point fibers: The melting of low melting point fibers is incomplete, mainly due to insufficient temperature. For non-woven fabrics with low basis weight, it is usually not easy to cause insufficient temperature. But for products with high basis weight and high thickness, special attention should be paid to whether it is sufficient. The non-woven fabric at the edge has enough heat, and the non-woven fabric is usually thicker, and the non-woven fabric in the middle part is easy to form a thinner non-woven fabric because of insufficient heat.

(3) The shrinkage rate of the fiber is high: whether it is a conventional fiber or a low-melting fiber, if the hot air shrinkage rate of the fiber is high, it is easy to produce uneven thickness due to shrinkage during the production of non-woven fabrics. The problem.
