  • Patent number: 4637859
    Abstract: Soft, absorbent paper webs and processes for making them. In the process, an aqueous dispersion of the papermaking fibers is formed into an embryonic web on a first foraminous member such as a Fourdinier wire. This embryonic web is associated with a second foraminous member known as a deflection member. The surface of the deflection member with which the embryonic web is associated has a macroscopic monoplanar, continuous, patterned network surface which defines within the deflection member a plurality of discrete, isolated deflection conduits. The papermaking fibers in the web are deflected into the deflection conduits and water is removed through the deflection conduits to form an intermediate web. Deflection begins no later than the time water removal through the deflection member begins. The intermediate web is dried and foreshortened as by creping. The paper web has a distinct continuous network region and a plurality of domes dispersed throughout the whole of the network region.

  • Patent number: 4636207
    Abstract: Disposable diapers provided with breathable leg cuffs. Disposable diapers comprise a topsheet, an absorbent element, and a backsheet. The leg cuff of a disposable diaper is that part of the diaper which fits about the wearer's leg. Extensions of the backsheet can be used to form cuffs which are frequently elasticized. In the present invention the cuffs are formed of a material which allows passage of vapor ("breathes") while tending to retard the passage of liquid. Apertured thermoplastic films are examples of such materials. Certain advantages accrue in cuffs which are permeable to vapor in their distal portions and impermeable in the portions adjacent the absorbent element. If the disposable diaper has a breathable backsheet, the cuffs are constructed to be more permeable to vapor per unit area in their breathable portions than is the backsheet.

  • Patent number: 4528239
    Abstract: Foraminous members useful in making paper webs. The foraminous member of this invention has a macroscopically monoplanar, patterned, continuous network surface which serves to define within the member a plurality of discrete, isolated, deflection conduits. A foraminous woven element, such as a screen, is thoroughly coated with liquid photosensitive resin to a controlled depth above the upper surface of the woven element. A mask or a negative having opaque and transparent regions which define the pattern is brought into contact with the surface of the liquid photosensitive resin and the resin is exposed to light of an activating wavelength through the mask. The resin exposed to the activating light is hardened (cured). Uncured resin is removed from the composite leaving behind the woven element with the solid network formed by the cured resin.

  • Patent number: 4515595
    Abstract: Disposable diapers having elasticized waistbands which allow the diapers to breathe and which reduce the incidence of waistband rollover. The waistbands are formed by affixing elastic elements between the topsheets and the backsheets (in the waistband region of the diapers) using regularly spaced, transversely extending regions of securement. Regions of nonsecurement are formed between pairs of the regions of securement thereby forming channels which allow the diaper to breathe and also forming corrugations which tend to inhibit waistband rollover.
