The present invention is directed to a substrate, in particular textile material to which one or more antimicrobial and/or hydrophilic and/or stain release agents are adhered. The agent(s) is/are adhered to the substrate in such a manner that they are not released from the textile even if the textile is wetted or washed, so that the textile is reusable. Washability and/or usability of the textile are improved where one or more hydrophilic and/or stain release agents are adhered to the textile. The substrate can be used, e.g., in a reusable sanitary napkin or other hygiene product. The structure of the hygiene product is disclosed, together with a process of attaching the different layers of the hygiene product together by ultrasonic welding. The invention further relates to a method of finishing a substrate by applying and binding antimicrobial and/or hydrophilic and/or stain release agents to the substrate so that the agents are essentially irreversibly adhered to the finished substrate.

A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

Disclosed herein are nucleotide analogs, methods of synthesizing nucleotide analogs and methods of treating diseases and/or conditions such as a HBV and/or HDV and/or HIV infection with one or more nucleotide analogs.

The present disclosure presents a process of forming an aqueous ink onto an ink receptive laminate of a liquid impermeable absorbent article film by ink-jet printing. The process generally includes the steps of corona treating the laminate, applying meltblown fiber onto the laminate and applying ink droplets that are smaller than the meltblown fiber onto the fiber and laminate. An ink-jet printed laminate is also disclosed.

The invention relates to a strip or lap comprising loops, in the form of a laminate with printed patterns. The laminate for forming a loop strip or lap, in particular the landing zone of nappies, includes at least one nonwoven layer having a lower face and an upper face opposite the lower face; at least one layer of ink applied to the upper face of at least the nonwoven layer; and at least one external textile layer from which loops project externally in order to engage with hooks of a self-fastening hook and loop device, at least one textile layer being secured to the upper face of at least the nonwoven layer.

The present invention relates to a disposable absorbent product such as a disposable diaper, a sanitary napkin, and the like and, more specifically, to: an absorbent product having a nano-coating layer, which is formed on the outer surface of a disposable absorbent product for absorbing excrement to be excreted from the body, thereby enabling overall air permeability of the product to improve and moisture to be blocked; and a manufacturing method therefor. To this end, in the absorbent product making contact with the body so as to absorb and store the excrement and the like to be excreted or discharged from the body, the present invention is characterized in that a nano-coating layer is formed on the outer surface, exposed to the outside, of the absorbent product in order to prevent the absorbed and stored moisture from being discharged to the outside and to ensure air permeability allowing outside air to circulate inside.

A biodegradable, disposable absorbent article, such as a diaper, having a non-woven inner layer of natural fibers and a non-woven outer layer of natural fibers and a treatment applied to at least one surface thereof. The treatment includes at least one compound selected from the group consisting of waxes, urethanes, silicones, fluorocarbons, and non-fluorochemical repellants. The absorbent article has a core of natural fibers or fibrous material, and optionally polyacrylate superabsorbent particles, positioned between the inner layer and the outer layer. The article may contain polylactic acid films between the layers.

A disposable absorbent article, having a front-back direction that is perpendicular to a width direction and a thickness direction that extends from a skin contact surface side to a non-skin contact surface side of a wearer, includes: an absorbent constituent; a liquid-permeable topsheet that is disposed on the skin contact surface side of the absorbent constituent; and a leakage-preventing sheet that is disposed on at least one of an outside, in the thickness direction, of the absorbent constituent, and an outside, in the width direction, of the absorbent constituent. The leakage-preventing sheet includes a water repelling layer including a nonwoven fabric. The nonwoven fabric of the water repelling layer includes fiber and has an average fiber diameter of 0.5 to 10 m. The water repelling layer includes a water repelling section where a group of particles adhere to a surface of the fiber.

The present disclosure includes cellulosic fiber barrier layer having a hydrophobic sizing to cause the barrier layer to exhibit hydrophobic properties. For example, the present cellulosic fiber barrier layers can be configured to have a high hydrostatic head (e.g., more than 200 mm H.sub.2O) while retaining a high air permeability (e.g., 0.5 ft.sup.3/min-ft.sup.2). The present disclosure also includes laminates (e.g., a breathable backsheet assembly) including one of the present cellulosic fiber barrier layers and a nonwoven support layer positioned beneath and coupled (e.g., bonded) to the barrier layer, such that the laminate is configured to exhibit desirable liquid-barrier performance (e.g., pinhole-free performance at 400 mm H.sub.2O for 10 minutes, and/or the like). The present disclosure also includes disposable absorbent garments including at least one of the present cellulosic fiber layers and laminates (e.g., including one of the present laminates as a backsheet for the disposable absorbent garment).
