摘要

A wipe having a multi-layer structure which is suitable for sanitary purposes is disclosed, wherein the wipe comprises: first and second non-woven web layers of discontinuous fibers which comprise rayon fibers, natural fibers and polymeric fibers, the first and second non-woven web layers being hydrophilic; anda spunbond-meltblown-spunbond web layer of continuous fibers disposed between the first and second non-woven web layers and positioned in facing and adjacently contacting relation with the first and second non-woven web layers, wherein the spunbond-meltblown-spunbond web layer comprises polypropylene or polylactide, and wherein at least one of the first and second non-woven web layers is bonded to the spunbond-meltblown-spunbond web layer by hydroentanglement, and 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).
