    摘要： A composite material adapted for barrier garment applications is made by laminating a film with an amorphous polymer layer to a prebonded nonwoven web under conditions producing laminate bonds corresponding to the prebond locations, and unbonded areas between the bonds while maintaining constant film thickness. The composite has enhanced resistance to viral penetration for use as a surgical gown material, for example, and also desirably has a MVTR of at least about 300 g/m2/24 hours and a hydrohead of at least about 50 mbar. In use as a component of a protective apparel such as a surgical gown or drape, the composite provides comfort and protection with reduced risk of film damage.

    摘要： A creped nonwoven web having permanent crepe includes regions of interfilament bonding which are permanently bent out-of-plane, alternating with regions of no interfilament bonding. The non-bonded regions include a multiplicity of filament loops which terminate at both ends in the creped interfilament-bonded regions. The creped nonwoven web is useful as the female component of a hook-and-loop fastener, and can also be used in diaper outercovers, liners, transfer and surge layers, wipers, and other fluid handling products.

    摘要： The present invention relates to an improved loop portion of a hook and loop fastening system. The loop portion is a two-layer composite including a compressively resilient backing material and a layer of fibrous loop material. The loop material is placed adjacent the bottom surface of the backing material and then a plurality of the loop fibers are needled or stitched through the backing material to form a plurality of loops which project above the top surface of the backing material. Due to the resilient nature of the backing material, when a hook member is brought into engagement with the loop material, the backing material compresses thereby exposing a greater portion of the individual loops for engagement with the hooks. Once the hooks have been engaged, the backing material expands back to make the exposed portion of the loops smaller. As a result, more individual engagements between hook and loop elements occur and there is less play between the hook members and loop elements thereby yielding a more firmly engaged hook and loop system as evidenced by increased peel strengths when compared to conventionally-backed loop structures. To add increased strength to the structure, the layer of loop material may contain an adhesive to bond the fibers and more firmly anchor the loops so as to lessen the chance of their disengagement during separation of the hook members from the loop members. Lastly, the adhesive employed may be a pressure-sensitive adhesive to permit the adherence of the loop structure to another substrate such as a diaper outercover.

    摘要翻译： 本发明涉及一种钩环紧固系统的改进的环部分。 环形部分是包括压缩弹性背衬材料和纤维环材料层的双层复合材料。 将环材料放置在背衬材料的底表面附近，然后多个环形纤维被针刺或缝合穿过背衬材料以形成多个环状物，该环状物在背衬材料的顶表面上方突出。 由于背衬材料的弹性，当钩构件与环材料接合时，背衬材料压缩，从而暴露出大部分单独的环以与钩接合。 一旦钩已经接合，背衬材料就会膨胀回来，使得环的暴露部分更小。 结果，钩和环元件之间发生更多的个体接合，并且在钩构件和环元件之间的游隙较少，从而产生更牢固地接合的钩环系统，如与常规支承的环结构相比，剥离强度增加所证明。 为了增加结构的强度，环材料层可以包含用于粘合纤维的粘合剂，并且更牢固地锚定环，以便在钩构件与环构件分离期间减少它们脱离的机会。 最后，所使用的粘合剂可以是压敏粘合剂，以允许环结构粘附到另一基底如尿布外罩上。

    摘要： The present invention is directed to a mechanical fastening system for use with disposable absorbent products. More particularly, a reinforced landing surface is disclosed for securing a hook-type mechanical fastener thereto. The reinforced landing surface includes a fibrous non-woven layer and a scrim-like web that is attached in a composite arrangement to the fibrous non-woven layer. The mechanical fasteners include a plurality of hooks, such as those used in a hook and loop type fastener which extend through the scrim-like web and penetrate the non-woven fibrous layer and become intertwined therewith. Depending upon the fastening requirements, the pattern of the scrim-like web may be repetitive, variable, continuous or discrete.

    摘要： A female component is provided for engaging a complementary hook component in a refastenable fastening device. The female component comprises a nonwoven web secured to a backing. The nonwoven web has characteristics that are specifically suited for entangling and holding the hooks of the mating hook component. The nonwoven web has a basis weight of between about 6 and about 42 grams/meter.sup.2. The nonwoven web may comprise, among other types of nonwovens, a carded web with fibers between about 2.5 cm. and about 13 cm. long, or a spunbonded web with continuous length fibers. The denier of the fibers should be between about 0.5 and about 15. The total area occupied by any bonds between the fibers comprising the nonwoven web is less than about six percent of the total area of the web. The nonwoven web is secured to the backing, preferably autogeneously. The total area occupied by both the bonds between the fibers comprising the nonwoven web and by the bonds between the nonwoven web and the backing is between about 10 percent and about 35 percent of the total area of the female component. A fastening device having a hook fastening component and a female component that comprises the nonwoven female component of the present invention is also provided. The fastening device can be used on disposable articles, such as disposable diapers.
