Curable prepregs possessing enhanced ability for the removal of gases from within prepregs and between prepreg plies in a prepreg layup prior to and/or during consolidation and curing. Each curable prepreg is a resin-impregnated, woven fabric that has been subjected to a treatment to create an array of openings in at least one major surface. Furthermore, the location of the openings is specific to the weave pattern of the fabric.

The present invention provides a process for modifying the surface of a polyvinyl alcohol film or fabric by applying heat and pressure to the film or fabric to increase the moisture on the surface which is held by the fabric and to coalesce the surface fibers and reduce the porosity of the surface.

Methods of making an artificial leather substrate from leather waste (e.g., shavings, such as wet blue, and/or pulverized trim scrap) and products formed using the artificial leather substrate are disclosed. In one example, the artificial leather substrate comprises a composite web comprising leather waste mixed with a lightweight web, a lightweight web atop the composite web, and another lightweight web atop the first lightweight web. A method of making the artificial leather substrate includes the steps of mixing one or more fiber components, leather shavings, and/or pulverized leather trim scrap to form the composite web; needle punching the composite web; and bonding the composite web.

Compositions are described that include an oil, a surfactant, and optionally a charged polymer complex, where the composition may also include an aqueous phase to provide a microemulsion. Methods of manufacturing the compositions are also described, along with methods of using the compositions in home care and personal care.

A polyamide woven fabric and has a light feeling and a chambray tone hue, as well as heat retaining properties due to sunlight absorption, and wind breaking properties. The polyamide woven fabric is a woven fabric including 20% or more by mass of a polyamide carbon black pigmented yarn that includes carbon black in a proportion of 1 to 5% by mass. The woven fabric has a total fineness of 5 to 55 dtex and a monofilament fineness of 0.5 to 2.2 dtex; and has a cover factor of 1000 to 2500. A down product incorporating the polyamide woven fabric is a product finished by stuffing downs into shell fabrics of this woven fabric in an amount of 100 to 500 grams per square meter of the shell fabrics, and then sewing together the shell fabrics.
