Patent number: 10028866Abstract: An article having as a component a section of nonwoven web formed predominately of polymeric fibers is disclosed. The section of nonwoven web may have a pattern of consolidating bonds impressed on the surface. The bonds may have at least one bond shape; and the bond shape may have a perimeter with a greatest measurable length and greatest measurable width. The perimeter may have a convex portion and an aspect ratio of length/width of at least 2.5. Other features may be imparted relating to the density and orientations of the bonds relative machine and cross directions of the web. The bond shape reflects the shape of a corresponding bonding protrusion on a bonding roller. It is believed that the shape, density and/or orientation of the bonding protrusions affect air flow through the bonding nip in a way that may be utilized to enhance loft of the resulting bonded nonwoven web.Type: GrantFiled: July 20, 2016Date of Patent: July 24, 2018Assignee: The Procter & Gamble CompanyInventors: Han Xu, Antonius Lambertus DeBeer, Olaf Erik Alexander Isele, Frantisek Klaska, Jiri Kummer, Zdenek Mecl, Pavlina Kasparkova

Patent number: 9993369Abstract: An article having as a component a nonwoven material, which includes a layer of spunbond fibers. The fibers of the nonwoven material are made of a composition that includes a first polyolefin, a second polyolefin that is a propylene copolymer and is different from the first polyolefin and a softness enhancer additive. The layer of fibers also includes a plurality of calendering bonds with an aspect ratio of at least 2.5.Type: GrantFiled: September 19, 2013Date of Patent: June 12, 2018Assignee: The Procter & Gamble CompanyInventors: Han Xu, Antonius Lambertus De Beer, Frantisek Klaska, Jiri Kummer, Zdenek Mecl, Pavlina Kasparkova, Jitka Zerehsaz, Jaroslav Kohut

Publication number: 20140072767Abstract: The present invention relates to a process of forming a soft bulky nonwoven web from a batt using thermobonding and to a soft bulky nonwoven web with a bond impression pattern and shape. The process comprises several steps including feeding a batt to a nip between first and second surface of first and second roller, where at least the first of the surfaces comprises spaced apart bonding protrusions surrounded by recessed areas. The bonding protrusions and the bond impression shape in the web exhibit a ratio of the greatest measurable width to the greatest measurable length of at least 1:2.5 and the perimeters thereof comprise a convex portion. The bonding protrusions are symmetric and/or have a certain angle to the machine direction.Type: ApplicationFiled: March 23, 2012Publication date: March 13, 2014Applicant: PEGAS NONWOVENS S.R.O.Inventors: Frantisek Klaska, Jiri Kummer, Zdenek Mecl, Pavlina Kasparkova, Han Xu, Olaf Erik Alexander Isele, Antonius Lambertus Johannes de Beer
