  • Publication number: 20210348316
    Abstract: Fabrics are provided that include mono-component staple fibers, a first group of split staple fibers comprising a first polymeric material, and a second group of split staple fibers comprising a second polymeric material that is different than the first polymeric material. The mono-component staple fibers, the first group of split staple fibers, and the second group of split staple fibers are physically entangled together to define a consolidated nonwoven. The fabrics may be physically entangled by hydroentanglement.

  • Patent number: 7816287
    Abstract: A flame retardant cellulosic-based nonwoven fabric is provided having a synergistic blend of cellulosic and acrylic fiber that imparts unexpectedly enhanced flame retardant performance. The flame retardant finished nonwoven fabric can have at least about 15 wt % and no greater than about 35 wt % acrylic fiber and at least about 65 wt % and no greater than about 85% cellulosic fiber, where the nonwoven fabric has a char strength of at least 0.9 Newtons and exhibits a basis weight loss of no more than 7 wt % when exposed to a gas flame for 240 seconds. Bedding articles including the flame retardant finished nonwoven fabric are also provided.

  • Publication number: 20040110456
    Abstract: A method of forming a nonwoven fabric suitable for metal-finishing buffing operations includes providing a precursor web comprising polyester, staple length fibers, with hydroentanglement of the web effected to impart desired physical characteristics. Hydroentanglement is effected on a three-dimensional, image transfer device having an array of three-dimensional surface elements for patterning the fabric which is formed. Application of a binder composition lends desired durability to the fabric, with the binder composition preferably including a melamine polymeric composition to achieve the desired strength and abrasion resistance.
