Non-woven knowledge training

SMS Introduction Course Introduction to Non-woven Knowledge Non-woven (Fabric) The scientific name is non-woven, or non-woven. Because it is a kind of fabric that does not need to be spun and weaves, it just oriented or randomly arrange the textile short fibers or filaments to form a web structure, which is then consolidated by mechanical, thermal bonding or chemical methods. Simply put, non-woven fabric is a cloth-like material made of fibers that does not require a weaving process.  Features of non-woven fabric Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple sources of raw materials. The history of non-woven fabrics Woven fabrics can be traced back to 7000 years ago. Modern non-woven fabrics really started with needle punched non-woven fabrics born in the UK in 1870; meltblown fabrics were produced in the United States in 1951; spunbond fabrics were invented in the United States in 1959. Non-woven fabric production in 2004, the world’s output was 4.5 million tons (110 billion square meters), and the fiber consumption accounted for 8% of the world’s fiber production. In 2004, China’s non-woven fabric production was 755,000 tons, accounting for 16.8% of the world’s total production.
