ITS HISTORY :
A non-woven product is any material that looks like a fabric but was not weaved: the long fibers are bonded together by a bonding agent.
The first non-woven appeared around 1890/1900. It is only in the 60’s that industrials started to be interested by this material allowing it to be spreaded widely.
The first patent regarding the hydroentanglement process (spunlace) was applied in 1961. The first non-woven was put on the market in 1973 by a US company.
The comsumption went from 40 000 tonnes in 1970 to 750 000 tonnes in 1997. In the beggining of the 21st century, consumption raised to 2 300 000 tonnes.
MANUFACTURING METHOD :
The production of non-wiven can be described in 3 steps that could be simultaneous:
– Formation of a web : entangling a web of loose fibers to form a sheet structure by subjecting the fibers to multiple rows of fine high-pressure jets of water.
– Consolidation of web by spunlace : the web is then compacted and dried.
With this method, the non-woven has specific properties: It is soft and has good traction resistance. Unlike non-woven chemically bonded, there is no additive.
– Finishing treatment.
PROCESS AND RAW MATERIALS USED BY AU FIL DU SOIN :
The company offers to its clients products made of viscose and polyester produced by spunlace.
