  • Patent number: 11622919
    Abstract: A water disposable nonwoven web having good MD and CD strength is provided. The nonwoven web is obtained by hydroentangling an airlaid web of no less than 50% by weight of natural cellulose fibers having a fiber length of no more than 3.5 mm and no more than 50% by weight staple fibers having a fiber length of no less than 8.0 mm. The nonwoven web contains no adhesive, binder or thermal bonding fibers. Products containing the disposable nonwoven web meet municipal guidelines for flushability.

  • Publication number: 20200255991
    Abstract: A fabric comprising a plurality of textile fibres, wherein said plurality of fibres comprises fibres that have been selected from two groups of fibres. The first group of fibres comprises multiple fibres having a first average length, and the second group of fibres comprises multiple fibres having a second average length, the first average length being shorter than the second average length. Further, the fibres of the first group have a first length variance being greater than a second length variance of the fibres of the second group. Thereby, the elongation properties of the fabric is changed in respect of the cross direction of the fabric, whilst maintaining almost unchanged strength in the longitudinal direction at a low basis weight.

  • Patent number: 10415166
    Abstract: A method to prepare nonwoven webs suitable for use as an industrial wipe which have good MD and CD strength is provided. The method includes hydroentangling an airlaid web of natural cellulose fibers having a fiber length of no more than 3.5 mm, bonding fibers having a fiber length of from 6.0 to 12.0 mm and optionally, manmade fibers having a fiber length of from 6.0 to 12.0 mm. The airlaid web is a homogeneous mat of the natural cellulose fibers, the optional manmade fibers and the bonding fibers and is not laid on a precursor web. No non-fiber adhesive or binder is utilized. The airlayering and hydroentangling are conducted in a continuous operation. The method to manufacture the nonwoven web may include an embossing or crepeing operation.

  • Publication number: 20180251925
    Abstract: A hydroentangled nonwoven fibrous composition, comprising as a hydroentangled web from 60 to 90% by weight of defibrated or refined natural cellulose fibers; and from 10 to 40% by weight of manmade sustainable fibers and a method to prepare the fibrous composition is provided. The nonwoven fibrous hydroentangled web comprises no binder, adhesive or thermal bonding fiber and has sufficient wet strength to be usable as a wipe and water dispersibility to be suitable as a flushable product for disposal in a municipal sewer system. A disposable wipe containing the hydroentangled nonwoven fibrous composition is also provided.
