摘要:
A method for anti-stain treatment of fabric is disclosed. The method for anti-stain treatment of fabric includes: immersing fabric in an aqueous solution containing a telomerized perfluoroalkyl acrylate copolymer, and a crosslinking agent, such as an isocyanate crosslinking agent; dehydrating the immersed fabric; drying the dehydrated fabric; heat treating the dried fabric; and coating the heat-treated fabric with a flame retardant, such as an acrylic flame retardant, to provide flame retardancy. The method provides a car seat fabric having superior stain resistance, water repellency and oil repellency without degradation of other properties required for the car seat fabric, such as flame retardancy, lightfastness, frictional coloration, or the like. The method is widely applicable to commercially applicable car seat fabrics, including flat woven, flat tricot, double raschel, or the like.

摘要:
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.

Disclosed is an olefinic thermoplastic composition for powder-molding, more particularly to a composition comprising polypropylene resin, hydrogenated styrene-butadiene rubber or styrene-ethylene-butylene-styrene copolymer rubber and ethylene-octene copolymer elastomer, which has a good melt fluidity, tensile strength and folding stability, and can be used for powder-molding of automobile interior materials and covering materials.
摘要:
A polyproplylene-based resin composition for powder slush molding which is a mixture of a polypropylene homopolymer, copolymer, or terpolymer; an olefin rubber; a styrene rubber; a process oil; and a polypropylene wax, wherein the composition is excellent in low-temperature impact resistance and heat resistance and has no offensive odor. The composition can be formed by a cryofreeze pulverization method in the presence of liquid nitrogen into a powder having an average particle size of 200 to 300 μm suitable for powder slush molding. The powder can be adhered to a polyurethane foamed layer and a surface treating agent without a primer coating. The powder is particularly suitable for forming the interior surface for manufacture of an automobile surface such as an instrument panel.
