Described herein is high-energy-violet-light (HEVL) absorbing benzotriazole vinylic monomers that have an adequate solubility in an organic solvent (e.g., 1-propanol), a better compatibility with polymerizable components present in a hydrogel lens formulation, and an absorption peak at a wavelength of from 410 nm to 425 nm. They are suitable for making hydrogel contact lenses that can significantly block HEVL from 380 nm to 450 nm but cannot block significantly blue lights (from 450 nm to 495 nm).

A method for producing a cellulose product from a multi-layer cellulose blank structure, wherein the method comprises the steps; forming the multi-layer cellulose blank structure from at least a first layer of dry-formed cellulose fibres and a second layer of a cellulose fibre web structure, through arranging the at least first layer and second layer in a superimposed relationship to each other and in the superimposed relationship arranging the at least first layer and second layer in contact with each other; arranging the multi-layer cellulose blank structure in a forming mould; heating the multi-layer cellulose blank structure to a forming temperature in the range of 100 C. to 300 C., and forming the cellulose product from the multi-layer cellulose blank structure in the forming mould, by pressing the heated multi-layer cellulose blank structure with an isostatic forming pressure of at least 1 MPa, preferably 4-20 MPa, wherein the multi-layer cellulose blank structure is shaped into a two-dimensional or three-dimensional fibre composite structure having a single-layer configuration.

A method for hydroforming a spun bonded nonwoven web includes applying a plurality of pressurized liquid jets onto an original unexpanded spun bonded nonwoven web having an original loft while the web passes over a forming structure. A plurality of spun bonded fibers in the original unexpanded spun bonded nonwoven web are reoriented from a closely packed substantially horizontal orientation to a more loosely packed orientation with greater vertical spacing between the fibers to produce a hydroformed expanded spun bonded nonwoven web having a loft of at least about 1.3 times greater than the original loft of the original unexpanded spun bonded nonwoven web, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed expanded spun bonded nonwoven web has a surface with a plurality of protuberances in a pattern corresponding to the pattern of apertures in the forming structure.

A method for hydroforming a composite precursor material includes forming a composite precursor material comprising an original spun bonded nonwoven web and a polymer film layer. The method also includes applying a plurality of pressurized liquid jets onto an outer surface of the original spun bonded nonwoven web while the composite precursor material passes over a forming structure to push and reorient a plurality of spun bonded fibers from a closely packed substantially horizontal orientation to a more loosely packed orientation with greater vertical spacing between the fibers to produce a hydroformed composite material comprising an expanded spun bonded nonwoven layer having a loft of at least about 1.3 times greater than the original loft of the original spun bonded nonwoven web, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web.

According to some embodiments of the present invention, there are provided a flowing water channel device, comprising, a tubular conduit made of fluid impervious material and at least one slit extending along a longitudinal axis of the tubular conduit, a first and a second marginal edge of the tubular conduit are opposing to one another, and at least one fluid permeable sheet material layer passing via the at least one slit and having a first marginal portion spread within the tubular conduit along the longitudinal axis and a second marginal portion spread outside of the tubular conduit along the longitudinal axis.

The present invention aims to provide a double container in which an inner bag is easily pulled out from a container body. According to the present invention, provided is a double container, comprising a container body and a cap, wherein: the container body comprises an inner bag, and an outer shell arranged to cover the inner bag; the cap is attached to a mouth part of the container body; the cap comprises an inner cap, and an overcap; the inner cap is engaged with the inner bag in an axial direction; the overcap is screw-engaged with the inner cap; and the double container is configured such that the inner bag can be pulled out from the container body by pulling the overcap in the axial direction.

A hydroformed expanded spun bonded nonwoven web has a first substantially planar surface on one side thereof and a second surface on an opposite side thereof. The second surface includes a plurality of protuberances in a pattern. The hydroformed expanded spun bonded web has an average loft of at least about 1.3 times greater than an original average loft of an original unexpanded spun bonded nonwoven web from which the hydroformed expanded spun bonded nonwoven web was created, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web.

A composite material includes a nonwoven layer having a plurality of fibers and a polymer film layer with a plurality of extended cells. Each of the extended cells are contemplated to include continuous sidewalls extending away from the nonwoven layer. At least one of the fibers extends into one or more of the extended cells.
