Nonwoven fabrics are called nonwoven fabrics in the standard. my country’s national standard GB/T 5709-1997 “Textiles Nonwoven Fabrics Terminology” defines nonwoven fabrics as: “Directed or randomly arranged fibers, combined with each other by friction, cohesion, or adhesion, or a combination of these methods to form sheets, webs or pads, excluding paper, woven fabrics, knitted fabrics, tufted fabrics, and wet-shrink felt products. The fibers used can be; can be short fibers, filaments or fibrous materials formed on the spot.”
Among them, the word “cloth” may make people think that its raw materials are natural materials, but in fact, the three major fibers used to produce non-woven fabrics are (accounting for 63% of the total), polyester (accounting for 23% of the total) and viscose fiber (accounting for 8% of the total), the remaining 2% are acrylic fiber, 1.5% are polyamide, and 2.5% are other fibers.
Among them, viscose fiber is a processed product of natural fiber, while polyester, polypropylene, acrylic acid and polyamide fibers are all chemical fibers, which are also the main polymer components of synthetic plastics. Non-woven fabrics made of these chemical fibers are all plastic products. It can be seen that the vast majority (89.5%) of non-woven fabrics on the market are difficult to degrade plastic products.
