Abstract
There is provided a laminate material having stretchability and recovery, breathability and barrier properties, and being made from a nonwoven elastomeric web having at least one web of textile material discontinuously adhesively bonded to each side thereof. The laminate material is free of an elastomeric film, the elastomeric web is substantially flat when the laminate is unstretched, and the nonwoven elastomeric web provides recovery to the laminate. The nonwoven elastomeric web is preferably a web of meltblown elastomeric fibers and the other webs may be knits, wovens or scrim materials. These laminates are well suited for infection control products, personal care products and garments.
Claims18
A laminate material having stretchability and recovery, breathability and barrier properties, comprising:
- a nonwoven elastomeric web having at least one web of textile material discontinuously bonded to each side thereof with an adhesive,
- wherein the laminate material is free of an elastomeric film, said elastomeric web is substantially flat when said laminate is unstretched, and the nonwoven elastomeric web provides recovery to the laminate.
A multi-use, launderable, laminate material having stretchability and recovery, breathability and barrier properties, comprising:
- a nonwoven meltblown polyester elastomeric web having at least one web of continuous filament polyester textile material also comprising about 4 weight percent of carbon fibers, discontinuously bonded to each side thereof with an adhesive to form a laminate,
- wherein the laminate material is free of an elastomeric film, said elastomeric web is substantially flat when said laminate is unstretched, and the nonwoven meltblown polyester elastomeric web provides recovery to the laminate, and;
- a topically applied low formaldehyde repellent material on said laminate.
A process for forming a laminate material having stretch and recovery, and having a flat surface when the laminate material is in the unstretched state, the laminate material being free of an elastomeric film, comprising the steps of:
- providing a first web of a material selected from the group consisting of a knit material, a woven material and a scrim material, proximate to a nonwoven elastomeric web;
- and
- joining the first web to the nonwoven elastomeric web through the agency of a discontinuously applied adhesive such that, when the joined first web and nonwoven elastomeric web are not stretched, the first web is substantially flat, the forming being performed without a elastomeric film such that the laminated material is free of an elastomeric film.
