A biocidal composite wall or surface fabric installable within an aircraft cabin or other vehicle interior space includes a flexible woven layer. The woven layer is treated on its outer surface with a biocidal polymer coating. For example, the polymer coating may incorporate biocidal microcapsules or nanocapsules configured for controlled release of biocidal compounds in response to physical contact or other stimuli. The released biocidal compounds compromise or kill microbial compounds deposited on the outer surface, e.g., via physical contact by passengers or crewmembers. The woven layer includes additional biocidal molecules incorporated into its fibers and strands, the biocidal molecules capable of biocidal action in response to contact with the fabric.

A self-healing fabric for an inflatable of an evacuation system may comprise a fabric layer, an interior thermoplastic polymeric layer formed over a first side of the fabric layer, and an exterior thermoplastic polymeric layer formed over a second side of the fabric layer. The interior thermoplastic polymeric layer may include a first healing agent. The exterior thermoplastic polymeric layer may include a second healing agent.

Disclosed is a method for preparing an automatic temperature control light conveyor belt, including: drying and setting a polyester fabric, to obtain a pretreated polyester fabric; blending microcapsules and TPU, and granulating, to obtain a modified TPU; coating a glue onto a surface of the pretreated polyester fabric, to obtain a coated polyester fabric; and calendering the modified TPU onto a surface of the coated polyester fabric, to obtain the automatic temperature control light conveyor belt.

The present invention provides a sheet structure comprising a carrier layer and a foamed cover layer which contains polyvinyl chloride, lignocellulosic based components and hollow microspheres, and a method for producing the sheet structure. The sheet structure can be used as an artificial leather, e.g. for flexible automotive interiors.

A non-solvent two-component polyurethane artificial leather composition is provided. The polyurethane composition comprises (A) a polyurethane-prepolymer component, comprising one or more polyurethane-prepolymers prepared by reacting at least one polyisocyanate compound with at least one first polyol, wherein the polyurethane-prepolymer comprises at least two free isocyanate groups; and (B) a polyol component, comprising at least one second polyol; wherein the polyol component further comprises an encapsulated foaming agent comprising at least one foaming core phase encapsulated within an outer shell. The polyurethane leather product derived from the polyurethane composition exhibits enhanced stability, mild bubble generation and improved cost effectiveness. A polyurethane leather product prepared with said composition and the method for preparing the same are also provided.

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 object of the present invention is to provide an interior trim surface material with a more excellent texture. The interior trim surface material of the present invention comprises a print layer on at least one main surface of a fiber aggregate, and has a main surface (a main surface on which the print layer is exposed in the interior trim surface material) with a surface roughness (SMD) of less than 2.71 m and an average frictional coefficient (MIU) of more than 0.27. When these conditions are satisfied, it is possible to provide an interior trim surface material that has an excellent texture, such as a feeling of high moistness, while still imparting a sensation that feels smooth and fine texture. Further, the interior trim surface material of the present invention comprises a print layer containing hollow particles having an average particle size of 106 m or less, whereby a feeling of resistance or sliminess is imparted, thereby achieving an interior trim surface material with a more excellent texture, such as a feeling of high moistness.
