Definitions
- Breathable elastic laminates are used in the manufacture of many goods, including, for example, disposable articles such as diapers, feminine sanitary articles, and bandages. These applications require that the laminate be strong, stretchable, and soft to the touch. Improving one of these features, however, tends to diminish the others. Consequently, previously-introduced laminates tend to represent a compromise among softness, elasticity, and strength.
- FIG. 2 shows a schematic of a manufacturing line for making the elastic laminate of FIG. 1 .
- the elastic laminate 10 comprises an elastic layer 12 having a first and second side, 14 , and 15 .
- the elastic layer has apertures 13 or is otherwise modified to be breathable.
- On the first side 14 is an activated nonwoven layer 16 bonded to the elastic film material 12 .
- the terms “activated” or “activation” refer to a method or state in which a laminate comprising an elastic layer and at least one less-elastic layer is stretched to an extension limit beyond the deformation point of the less-elastic layer to allow the elastic layer to elongate to the extension limit essentially unimpeded by the less-elastic layer.
- the first nonwoven layer 16 provides a soft and breathable surface once activated (discussed below) on the first side 14 of the elastic layer.
- Suitable nonwovens are capable of being activated and are less elastic than the elastic layer 12 .
- Suitable nonwovens include loose fibers and webs prepared using know techniques such as, for example, air laying, spun bond, spun lace, bonded melt blown, thermobond, bonded carded.
- the nonwoven material may be homogeneous or contain a variety of woven materials including bi-component fibers (e.g. having an inner core of one material and an outer core of a second material), fibers of different morphologies, geometries, and surface finishes.
- Suitable nonwovens materials include, for example, fibrous polyolefins such as polyethylenes and polypropylenes, and natural fibers such as cotton and cellulose.
- the degree of activation may be varied, for example, a lightly activated area may be used to give a laminate low elasticity, while a heavily activated area may be used to give a laminate high elasticity.
- activated regions may be interposed with nonactivated regions as well, to provide zones or regions of extensibility to the laminate.
- Varying the materials and method conditions may vary the characteristics of the laminate. For example, selection of particular elastic and/or nonwovens, or selective processing of those materials, can result in optimization of desired properties such as bond strength, softness, elasticity, breathability, etc.
- Examples of method variables that may be used to modify laminate characteristics include modifying the phase of the elastic layer prior to bonding; modifying the pressure differential applied by a pressure differential source; modifying pressure imposed by a pressure source; modifying apertures in a nonwoven; modifying apertures provided in an aperture definition device; various secondary treatments of the laminate and/or components of the laminate (e.g. plasma treatment), modifying stretching of a laminate following lamination, and combinations thereof.
- a laminate may also be modified in any suitable fashion, for example, a laminate may be sewn, bonded, printed, cut, shaped, glued, fluted, sterilized, etc.
