Abstract
A method for manufacturing a non-woven/sheet laminate, involves preparing a sheet having a first and a second side, the sheet being made from a film or foil which is not a non-woven material. A first non-woven layer is disposed on the first side of the sheet and a second non-woven layer is disposed on the second side of the sheet, a visible side of the second non-woven layer having a linting coefficient of less than 2.7 and a sliding coefficient of friction of between 0.35 and 0.75. At least one of the first and the second non-woven layers comprises spunbond and meltblown layers with an outwardly facing spunbond layer. The non-woven/sheet laminate is subjected to a thermal treatment process and associated reduction in length in a flat direction.
Claims23
A method for manufacturing a non-woven/sheet laminate, the method comprising the steps of:
- a) preparing a sheet having a first and a second side, said sheet being made from a film or foil which is not a non-woven material;
- b) disposing a first non-woven layer on said first side of said sheet;
- and
- c) disposing a second non-woven layer on said second side of said sheet, wherein a visible side of said second non-woven layer has a linting coefficient of less than 2.7 and a sliding coefficient of friction of between 0.35 and 0.75, at least one of said first and said second non-woven layers comprising spunbond and meltblown layers with an outwardly facing spunbond layer;
- and
- d) subjecting, following steps a) through c), the non-woven/sheet laminate to a thermal treatment process and associated reduction in length in a flat direction.
