The polyurethane synthetic leather prepared by the present invention has daily life antifouling properties, a good durability, is soft to the touch, is strongly skin-friendly, and has a very superior flame-retardant performance, and also has excellent antifouling, scratch resistance and flexure resistance properties; the production process is simple, efficient and environmentally friendly and same can satisfy market demands.
LARGE SCALE MANUFACTURING OF HYBRID NANOSTRUCTURED TEXTILE SENSORS
A process for the large-scale manufacturing vertically standing hybrid nanometer scale structures of different geometries including fractal architecture of nanostructure within a nano/micro structures made of flexible materials, on a flexible substrate including textiles is disclosed. The structures increase the surface area of the substrate. The structures maybe coated with materials that are sensitive to various physical parameters or chemicals such as but not limited to humidity, pressure, atmospheric pressure, and electromagnetic signals originating from biological or non-biological sources, volatile gases and pH. The increased surface area achieved through the disclosed process is intended to improve the sensitivity of the sensors formed by coating of the structure and substrate with a material which can be used to sense physical parameters and chemicals as listed previously. An embodiment with the structures on a textile substrate coated with a conductive, malleable and bio-compatible sensing material for use as a biopotential measurement electrode is provided.
MAN-MADE LEATHER HAVING EXCELLENT AIR PERMEABILITY AND MANUFACTURING METHOD THEREOF
The present invention relates to a man-made leather having excellent air permeability and manufacturing method thereof, and more particularly, to a man-made leather having excellent air permeability capable of maintaining a permeability by urethane-coating only on a cotton portion of base fabric (20) formed with holes and capable of pattern transfer on release paper, and manufacturing method thereof.
According to the man-made leather having excellent air permeability and manufacturing method thereof, the air permeability can be maintained on the man-made leather by urethane-coating only on a cotton portion of base fabric (20) formed with holes while maintaining the luxury of fabric texture per se and toughness.
Method of preparing water-based surface treatment agent and water-based surface treatment agent prepared using the same
The present invention relates to a method of preparing a water-based surface treatment agent and a water-based surface treatment agent prepared using the same. More particularly, the present invention relates to a water-based surface treatment agent used to form a surface treatment layer included in artificial leather for automobile seat covers and a method of preparing the water-based surface treatment agent. According to the present invention, when the water-based surface treatment agent is used to manufacture artificial leather, occurrence of whitening of the surface of the artificial leather may be prevented.
