Abstract
A wipe including at least one non-woven web layer of discontinuous fibers; and a spunbond-meltblown-spunbond web layer of continuous fibers positioned in facing and adjacently contacting relation with the at least one non-woven web layer, wherein the wipe has an opacity index of at least 1.3, where the opacity index is calculated based on the following equation: opacity index=(opacity of the wipe)/(total basis weight of the wipe).
Claims44
A wipe comprising:
- at least one non-woven web layer of discontinuous fibers;
- and
- a spunbond-meltblown-spunbond web layer of continuous fibers positioned in facing and adjacently contacting relation with the at least one non-woven web layer, wherein the wipe has an opacity index of at least 1.3, where the opacity index is calculated based on the following equation:
- opacity index=(opacity of the wipe)/(total basis weight of the wipe).

A wipe comprising:
- at least one non-woven web layer of discontinuous fibers;
- and
- a spunbond-meltblown-spunbond web layer of continuous fibers positioned in facing and adjacently contacting relation with the at least one non-woven web layer, wherein the wipe has a combination index of at least 0.7, where the combination index is calculated based on the following equation:
- combination index=[((opacity of the wipe)(cross dimensional tensile strength of the wipe)(1/cross dimensional elongation of the wipe))/(total basis weight of the wipe)3](10000).
1 more element
A method of forming a wipe, comprising the steps of:
- forming at least one non-woven web layer of discontinuous fibers;
- forming a spunbond-meltblown-spunbond web layer of continuous fibers;
- and
- bonding the at least one non-woven web layer with the spunbond-meltblown-spunbond web layer, wherein the wipe has an opacity index of at least 1.3, where the opacity index is calculated based on the following equation:
- opacity index=(opacity of the wipe)/(total basis weight of the wipe).
