摘要:
There is provided a laminate of a thermoplastic backing to a fibrous web. This laminate, for example, could be used as a loop laminate for use in a hook and loop fastening system or an intermittently bonded elastic fibrous laminate. The laminate comprises a thermoplastic backing layer, having a first face and a second face. The backing layer has a plurality of projections extending from at least the first face of the backing. A fibrous web is attached to the backing at the location of at least some of the projections. The thermoplastic material of the backing, at the location of the projections, penetrates into the fibrous web encapsulating at least in part fibers of the fibrous web. The fibrous web preferably penetrates into at least some of the projections. The fibrous web is generally not attached, or very lightly attached, to the backing layer over at least some portion of the distance between adjacent projections. This allows for a low cost fibrous web laminate that can be directly extrusion formed with a backing without compromising the fibrous web's performance between the attached projections.
摘要(中):
提供了热塑性背衬到纤维网的层压材料。 例如,该层压体可以用作环形层压板,用于钩环紧固系统或间歇粘合的弹性纤维层压材料。 层压板包括具有第一面和第二面的热塑性背衬层。 背衬层具有至少从背衬的第一面延伸的多个突起。 纤维网在至少一些突起的位置处附着到背衬上。 背衬的热塑性材料在突起的位置处穿透至纤维网中至少部分地包裹纤维网的纤维。 纤维网优选地渗入至少一些突起中。 纤维网通常在相邻突起之间的距离的至少一些部分上不附着或非常轻微地附接到背衬层。 这允许低成本的纤维网层压板,其可以直接用背衬挤出形成,而不会影响纤维网在附接的突起之间的性能。
