  • Patent number: 11718962
    Abstract: A nonwoven web, containing at least one first homogeneous layer consisting of a blend of at least one of defibrated natural plant based fibers, individualized natural plant based fibers and staple fibers is provided. The nonwoven web contains no binder, adhesive or thermal bonding fibers and a basis weight of the at least one homogeneous layer is from 20 g/m2 to 100 g/m2. When a weighted average fiber length of the blend is greater than about 4.0 mm, the nonwoven web is a non-dispersible product which does not meet the requirement for dispersibility in accordance with INDA/EDANA GD4, and when a weighted average fiber length of the blend is less than about 4.0 mm, the nonwoven web is a dispersible product as defined in accordance with INDA/EDANA GD4. Methods to prepare the nonwoven web are provided.

  • 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.
