Abstract
The present invention is directed to a method of making a laminate nonwoven fabric which entails integration of a continuous filament web with a web of cellulosic fiber material, typically wood pulp. In order to abate loss of cellulosic fiber material during integration by hydroentanglement, the present invention contemplates that the continuous filament web is first subjected to hydroentanglement, with the cellulosic fibrous material thereafter integrated, by hydroentangling, into the partially entangled continuous filament web.
Claims10
A method of making a laminate nonwoven fabric, comprising the steps of:
- providing a continuous filament web;
- hydroentangling said continuous filament web to form a partially entangled web;
- juxtaposing a cellulosic fiber web with said partially entangled web;
- hydroentangling said juxtaposed partially entangled web and cellulosic fiber web;
- and
- drying said hydroentangled webs to form said nonwoven fabric.
A method of making a laminate nonwoven fabric, comprising the steps of:
- providing a continuous filament web;
- providing a foraminous surface;
- hydroentangling said continuous filament web to form a partially entangled web;
- juxtaposing a cellulosic fiber web with said partially entangled web;
- advancing said juxtaposed partially entangled web and cellulosic fiber web onto said foraminous surface and hydroentangling said webs on said surface so as to impart at least one three-dimensional image into said laminate;
- and
- drying said hydroentangled webs to form said nonwoven fabric.
A method of making a laminate nonwoven fabric in accordance with claim 6, wherein said foraminous surface is a three-dimensional image transfer device.
