A non-asphaltic breathable sheet is provided that includes at least one breathable polymer layer and at least one nonwoven layer. The breathable sheet may include an open-mesh reinforcing fabric embedded in a breathable polymer layer. The breathable sheet has an advantageous balance of strength, water resistance, and permeability to water vapor.

A composite laminate comprising at least one moisture vapor permeable nonwoven sheet having first and second surfaces and a fluorinated polymeric coating on the first surface of the sheet wherein (i) the fluorinated polymeric coating is present in an amount such that the total fluorine content of the coated non-woven sheet is 0.05 to no greater than 0.4 gsm, and (ii) the composite laminate, after exposure to wet timber, exhibits a retained hydrohead of at least 60 percent.

Disclosed herein are improved methods for bonding textiles using an adhesive composition.

Provided are a sound-absorbing membrane, a sound-absorbing material, and methods of manufacture therefor that can provide suitable sound absorbing performance, suppressed deterioration in appearance quality, and easy production. A sound-absorbing membrane 10 includes: a base sheet 11 made of a nonwoven fabric having a airflow resistance of 0.01 to 0.1 kPa.Math.s/m; and a resin film 12 covering one surface of the base sheet, the resin film 12 made of a thermosetting resin in a semi-cured state. Fillers 13 made of powder having an average particle diameter of 1 to 100 m are dispersed in the resin film 12. The sound-absorbing membrane 10 has a whole airflow resistance of 0.2 to 5.0 kPa.Math.s/m. A sound-absorbing material 20 includes a sound absorbing base sheet 21 made of a porous material, and the sound-absorbing membrane 10 laminated on one surface or both surfaces of the sound absorbing base sheet 21 such that the resin film 12 faces the sound absorbing base sheet 21, the sound-absorbing material 20 has a predetermined shape.

The present invention provides porous polymer coatings having adhesive and air flow resistive properties. The porous polymer coating comprises a polymeric foam having a void fraction of greater than about 15% and an air permeability greater than 3 cubic feet per minute per square foot as measured based on ASTM D737-04, wherein the polymeric foam comprises a clay and/or pigment optionally having an aspect ratio of about 2:1, 5:1, or 10:1 to about 20:1, 50:1, or 100:1. In some embodiments, the porous polymer coating comprises a chlorinated polymer and a fluorochemical.

Aspects herein relate to apparel items and apparel systems that utilize applied or printed foam nodes to provide, among other things, stand-off between an apparel item and a wearer's skin surface. One or more of the foam nodes, or areas of the textile surrounding the foam nodes, may be perforated to provide a fluid communication path between an inner-facing surface and an outer-facing surface of the apparel item. The communication path may be used to facilitate air exchange between the external environment and the wearer's body and/or to provide an exit path for moisture vapor generated by the wearer.

A method for manufacturing gloves includes adding a thickening agent (B) having an oxyethylene group content of 210.sup.2 mol/g or less to an aqueous urethane resin composition containing an aqueous urethane resin (A) having an acid value of 0.01 mgKOH/g or higher in a range of 0.01 to 30 parts by mass relative to 100 parts by mass of the aqueous urethane resin (A) to obtain a thickened liquid; and (i) immersing fiber-knitted gloves in the thickened liquid and subsequently performing coagulation in a coagulation bath (C) containing a metal salt (c-1) or (ii) immersing fiber-knitted gloves previously immersed in a coagulation bath (C) containing a metal salt (c-1) in the thickened liquid to perform coagulation. As the thickening agent (B), a cellulose thickening agent, an acryl thickening agent, or a urethane thickening agent can be used. Furthermore, as the metal salt (c-1), calcium nitrate can used.

Provided is a composite thermal insulation sheet including an aerogel and a method for manufacturing method the same. The methods yield an ultra-thin aerogel composite sheet having characteristics of low dust, high strength and high thermal insulation, thereby having an increased applicability thereof to an electronic device.

A composite formed by combining a perforated face layer and a backing scrim to make a material having sufficient airflow, tear strength and aesthetic features applicable to seating.
