Non-woven fabric is a new generation of environmentally friendly materials. It has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, difficult to decompose, non-toxic and non-irritating, diverse colors, low price, and recyclable. Non-woven fabrics are widely used in automobiles, and have gradually replaced the raw materials of many materials such as previous automobile interiors and sound insulation cotton.
The manufacturing principle of non-woven fabrics used in automobiles:
1. Non-woven fabric refers to the fabric that is never woven, so many punctured needles are used to wind the fibers together, or partially adhere to the fabric.
2. People have invented the manufacturing principle of non-woven fabrics at the end of the 20th century. The first company that produced this factory scale was a company in the United States in 1939, and a company in Europe and Germany also started non-woven fabric production around 1944. produce.
The production of non-woven fabrics in Japan started with a company in 1958, and seven companies joined in the following two years. Now the uses, materials, and manufacturing methods of non-woven fabrics have increased, and they have become an inseparable part of our lives. The mystery is that depending on the raw materials and processing methods, flexibility, thinness, various properties and shapes can be created by rights.
Advantages of non-woven fabrics:
Breathability, filtration, heat preservation, water absorption, water resistance, stretchability, never messy, good hand feel, soft, light, elastic, recoverable, no directionality of the fabric, low productivity compared with textile fabrics, The production speed is slow, the price is high, and mass production is possible.
