  • Patent number: 11479888
    Abstract: A nonwoven fabric having polylactic acid-containing fibers forming a nonwoven web is provided. The web has a side having an alternating pattern of individualized bonded areas which bonded areas define rods arranged in the cross direction of the web. The rods are arranged so that in the machine direction of the web no uninterrupted regions exist along the web while in the cross direction the arrangement of rods defines uninterrupted regions that extend continuously along the web, the alternating pattern of individualized bonded areas defines a non-bonded area. The web has a basis weight from 5-50 g/m2, the surface of the bonded areas is from 5-20% of the total surface of the side, and the surface of the non-bonded area is from 80-95% of the total surface of the side. Processes for forming the nonwoven fabric and an absorbent article including the nonwoven fabric are also provided.
