  • Patent number: 9803072
    Abstract: Disclosed are a resin composition and a molded article using the same. The resin composition may be obtained by mixing a thermoplastic vulcanizate and a polyethylene resin with a thermoplastic olefin resin, a polypropylene resin, an inorganic filler and a thermoplastic rubber, and in particular, the thermoplastic vulcanizate and the polyethylene resin may be obtained from biologically obtainable materials (biomass). Thus, the resin composition may be environmentally-friendly because it does not emit offensive odor of harmful compounds due to decreased generation of carbon dioxide and volatile organic compounds unlike petroleum-based materials. Further, superior mechanical properties such as elongation, hardness, strength, etc. that cannot be achieved only with conventional biodegradable resin may be ensured, and, at the same time, processability and moldability may be improved.

  • Patent number: 9644312
    Abstract: Disclosed is a synthetic leather produced by directly coating a water-soluble synthetic resin solution on the surface of a fabric to form a film thereon such that fine gaps formed on the fabric are partially left open to have a certain degree of air permeability. In particular, a brushing process is used for brushing the surface of a fabric using a brushing machine to raise a nap. Next, a hydrolysis-resistant and flame-retardant resin solution is coated on the back of the fabric, which is opposite to the surface on which the nap is raised, to reinforce the back of the fabric. A film forming process then applies a water-soluble polyurethane resin solution to the nap raised on the surface of the fabric to form a film on the surface of the fabric thereby producing a synthetic leather product that has air permeability properties that are superior to genuine leather.

  • Patent number: 9523192
    Abstract: Disclosed are a sound-absorbing material with improved sound-absorbing performance and a method for manufacturing the sound-absorbing material. The sound-absorbing material may improve sound absorption coefficient and transmission loss by forming large surface area and air layer, so as to induce viscosity loss of incident sound energy, and may provide light-weight design of a sound absorbing part or material since sound-absorbing performance may be substantially improved using reduced amount of fiber. Further, the sound-absorbing material may improve sound-absorbing performance by using binder fiber having rebound resilience, so as to maintain enough strength between fibers and also to maximize viscosity loss of sound energy transmitted to fiber structure.
