Car nonwoven manufacturing principles
2015-04-03
1. Non-woven weave without means, but with a lot of barbed needles intertwined fibers, or make it part of the fabric from sticking together.
2. In the early 20th century, people have invented nonwoven manufacturing principles, the first factory-scale production is the 1939 American Felt Company (American Felt Co.), About 1944 companies in Europe, Germany KARLFREUDENBERG also began production of non-woven fabrics.
Japan's non-woven production began in 1958 DAINIKKU Corporation, followed by another two years, seven companies to join. Purposes, the use of materials, manufacturing methods are now non-woven fabrics have increased, has become an integral part of our lives. Its secret lies according to different raw materials and processing methods, flexibility, thickness degree, various properties and shapes can freely create.
3. The nonwoven fabric has many advantages: 1) breathable 2) filterability 3) insulation 4) water-absorbent 5) waterproof 6) stretchable 7) does not disheveled 8) feel good, soft 9) light 10) elastic can recover 11) no directional fabric 12) compared with the production of textile fabrics with high production speed 13) low price, can be mass-produced, and so on.
The disadvantage is that: 1) Compared with the poor strength and durability of the textile fabric 2) is not the same as other fabrics washed 3) fibers are aligned in a certain direction, it is easy to cleave from the perpendicular direction, and so on. Therefore, the recent improvement in the production process primarily on improvements to prevent splitting.
4. A method of manufacturing a wet method is broadly divided into water (7% in Japan, accounting for 1-2% worldwide) and no water in the dry method (93% in Japan, the world 98 to 99%) . Others include hot air or heat and pressure fixing method (thermal bonding, wire bonding, etc.) and a method using an adhesive (chemical bonding), and so on.
Japan 2001 manufacturing methods were as follows:
Chemical bonding 42,975 tons (14%)
Thermal bonding 40,610 tonnes (14%)
Needle punching method 86,127 tons (29%)
Pull Ties France 16,431 tons (.6%)
Wire bonding 81,248 tons (27%)
Other dry process 9,022 tons (.3%)
Wet process 21,625 tons (.7%)
Total 298,038 tons (100.0%)
Wire bonding is used only for long fibers. Other full use of short fibers.
5.2001 in the domestic share of different materials as follows:
Polyester 104,757 ton (33%)
Polypropylene 81,678 tons (26%)
Nylon 13,370 tons (4%)
Other synthetic 40,062 tonnes (13%)
17,735 tons of viscose rayon fiber (6%)
Wood pulp 20
