Application prospects of non-woven shopping bags

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, it is used It can be formed by strengthening by mechanical, thermal bonding or chemical methods.


1. 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.


2. 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 environmental protection bags are mostly heat-sealed non-woven fabrics.


3. The 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.


4. 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 to 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 is small in size 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.
