Abstract
In a process for forming a nonwoven reinforced cellulosic material, for use in applications such as wipes and disposable clothing, which comprises applying adhesive to a ply of nonwoven scrim, bringing at least one cellulosic ply into contact with the scrim to form a substantially unbonded laminate, the improvement comprising applying pressure to discrete regions of said substantially unbonded laminate while said adhesive is in an activated condition. The application of pressure to discrete regions achieves ply attachment at only intermittent points on the scrim and can also serve to provide an embossed laminate texture. The product so formed is strong and has desirable absorbency, texture, bulk, hand and limpness.
