Absorbent article with improved fluid movement and soft touch
A recently granted patent (Publication Number: US11992395B2) discloses a method for manufacturing an absorbent article with specific features. The method involves creating a top-surface sheet with a non-heat fusible layer made of 100% cotton fiber on the skin side and a heat-fusible layer on the non-skin side. A second sheet made of heat-fusible fiber is added to the non-skin side of the top-surface sheet, with compressed parts formed on its surface. The manufacturing process includes passing the laminate of the top-surface sheet and the second sheet between a flat roll and a convex roll, where heat-fusing and joining occur, resulting in the formation of the compressed parts.
Furthermore, the patent details an alternative method for manufacturing the absorbent article, which involves additional steps to create compressed parts on the non-skin side surface of the top-surface sheet. This method includes passing the top-surface sheet between a flat roll and a convex roll to form intermediate compressed parts, followed by laminating the second sheet on the non-skin side of the top-surface sheet. Subsequently, the top-surface sheet passes between a second set of rolls for further heat-fusing and joining, resulting in the final formation of compressed parts. Both methods emphasize the formation of compressed parts in an intermittent pattern, enhancing the overall design and functionality of the absorbent article.
