Backing material for laminations

The non woven material (12), as a backing for laminations (10), is bonded by a water jet action. The non woven has a resistance to cracking of \- 450 kPa with a lateral draw strength of \- 4.8 N, in a thickness of \- 0.1 mm. The material is a wet non woven, in a mixture of cellulose and polyester fi...

Beschreibung
Zusammenfassung:	The non woven material (12), as a backing for laminations (10), is bonded by a water jet action. The non woven has a resistance to cracking of \- 450 kPa with a lateral draw strength of \- 4.8 N, in a thickness of \- 0.1 mm. The material is a wet non woven, in a mixture of cellulose and polyester fibers, with a bonding agent pref. using an acrylate dispersion. Or the material is a dry non woven composed of polyester or other man-made fibers. The non woven can be coated with a layer of glue, polyvinyl acetate (PVAc) or polyacrylate. The lamination has a thickness of \- 0.1 mm and preferably 0.1-0.8 mm. The lamination is ground to the required thickness for flexibility.
