The application prospect of non-woven shopping bags

The production of non-woven fabrics breaks through the conventional textile processing principle. It is a kind of textile material that does not require spinning and weaving. As long as the short fibers or filaments for textile use are oriented or randomly arranged to form a web structure , and then it can be formed by mechanical, thermal bonding or chemical reinforcement.

1. 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 transmission and moisture permeability It has the characteristics of strong, high air permeability, non-toxic and non-irritating; in addition, it can be recycled for many times, degradable or recycled, and has the advantages of light texture, softness, elasticity, corrosion resistance, and washability. Non-woven fabrics have fast production speed, short process flow, low cost, high output, wide raw material sources and uses, and rich colors.

2. 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 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.

3. Characteristics of non-woven shopping bags

Plastic bags commonly used in daily life are non-degradable, or the degradation years will take decades or even several 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.

4. 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.
