Proposed are an organic-inorganic composite synthetic resin using a highly flame-retardant organically modified nanoparticle, and a production method thereof. The method for producing the organic-inorganic composite synthetic resin using a highly flame-retardant organically modified nanoparticle includes the steps of: adding and stirring metal ion-based phosphinate, melamine cyanurate, and nanoclay to a container containing an aqueous or oily solvent, applying ultrasonic waves and high pressure energy to the stirred solution to prepare a highly flame-retardant organically modified silicate solution through a chemical bonding, and then adding a synthetic resin to form synthetic leather and foam used as life consumer goods to the silicate solution, processing and drying it.

Proposed are an eco-friendly automotive interior part, a method of manufacturing the same, and a method of designing the same automotive interior part. The automotive interior part can not only optimally correct physical properties thereof using manufacturing and design methods, but also have eco-friendliness by significantly reducing harmfulness to the human body due to the minimized use of chemicals, while realizing natural wrinkles resembling those of natural leather.

A method for producing a support for polyurethane-based imitation leather free of dimethylformamide or other solvents or water involves preparing a base. A two-component polyurethane layer is sprayed on the base which includes preparing a first component and a second component. The first and second components are combined to obtain a mixture, and the mixture is sprayed uniformly on the base forming the polyurethane layer. A backing is applied on the two-component polyurethane layer forming a support and the support is dried.

An imaging system includes a pixel array configured to generate image charge voltage signals in response to incident light received from an external scene. An infrared illumination source is deactivated during the capture of a first image of the external scene and activated during the capture of a second image of the external scene. An array of sample and hold circuits is coupled to the pixel array. Each sample and hold circuit is coupled to a respective pixel of the pixel array and includes first and second capacitors to store first and second image charge voltage signals of the captured first and second images, respectively. A column voltage domain differential amplifier is coupled to the first and second capacitors to determine a difference between the first and second image charge voltage signals to identify an object in a foreground of the external scene.

A method of manufacturing a functional fabric includes the steps of: (a) providing an undyed base fabric having a top surface and a bottom surface opposite to the top surface; (b) forming a moisture-permeable waterproof layer on the top surface of the base fabric; and (c) forming at least one pattern layer on at least one of the moisture-permeable waterproof layer or the bottom surface of the base fabric.

A skin material includes a loop pile fabric including fibers including polyester fibers, and an adhesive layer and a skin layer, which are disposed, in this order, on a surface of the loop pile fabric at a side at which pile yarns are provided, in which at least top parts of the pile yarns are located in the adhesive layer, and a gap is formed between a ground structure of the loop pile fabric and the adhesive layer.

The description relates to solvent free films and textiles that receive the solvent free films.

A skin material containing, in the following order: a base fabric that is configured to contain fibers having a synthetic resin coating layer, wherein fibers adjacent to each other in the base fabric are at least partially fused with each other; and an adhesive layer and a skin layer, which are provided at a surface of at least one side of the base fabric in this order from the base fabric, the skin material having a plurality of ventilation holes passing through the skin material in a thickness direction.
