  • Patent number: 6809048
    Abstract: The present invention provides a process for producing a three dimensionally texturized liquid resistant laminate having a fibrous nonwoven layer and a liquid resistant layer. The process has the steps of placing the fibrous layer and the liquid resistant layer in juxtaposition to form a laminate, attaching the fibrous layer and the liquid resistant layer at a plurality of spaced-apart bond locations, heating the bonded laminate to a temperature that activates the latent shrinkability of the liquid resistant layer, and allowing the heated laminate to retract such that the liquid resistant layer shrinks and said fibrous layer forms gathers between said bond locations, thereby forming a three dimensional texture and heat annealing the laminate. The invention additionally provides a three dimensionally texturized laminate having a fibrous layer and a nonelastic liquid resistant layer.

  • Patent number: 6479061
    Abstract: The present invention pertains to an airlaid composite which is made of pulp fibers, at least about 2% by weight bicomponent fiber, and moisture. This airlaid composite is unique in that a uniformly even composite is made which upon calendering, becomes a thin structure which maintains significant absorbency when saturated. The bicomponent fibers of the present invention include a first polymer component and a second polymer component, and the first polymer component melts at a temperature lower than the melting temperature of the second polymer component. Mixing of the pulp fibers with the bicomponent fibers is done in such a way that the fibers are evenly dispersed in the airlaid composite. This airlaid composite is then heated such that at least a portion of the first polymer component of the bicomponent fiber is melted, which bond the bicomponent fibers to many of the pulp and bicomponent fibers when cooled.

  • Patent number: 6245271
    Abstract: Process for die extrusion of melted polymers that reduces die lip buildup and its deleterious effects. Direct extrusion of mixed polymer pellets and filler concentrate pellets in one embodiment avoids a precompounding step and reduces the tendency of polymer and filler particles to adhere to the exit portion of the die. In other embodiments a reduced die lip radius and lower melt processing temperatures further enhance the benefits obtained. For co-extruded muitilayer film embodiments elimination of fillers and antiblock additives in skin layers add to the levels of die lip buildup reduction obtained. Hours of continuous operation without excessive die lip buildup in one arrangement have been increased from a level of 4 to 6 hours, for example, to in excess of 20 hours. Reduced product defect levels have also been attained.
