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.
The main properties of non-woven fabrics
Non-woven fabric is composed of filaments that are laid on each other to form a net, with high porosity, good light transmission, strong moisture permeability, high air permeability, non-toxic and non-irritating [2]; in addition, It can be recycled for many times, can be degraded or recycled, and has the advantages of lightness, 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.
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.
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.
