Provided herein is an eco-friendly artificial leather for an interior of an automobile and a manufacturing method thereof. The eco-friendly product is manufactured using a method that is compatible with various environmental regulations such as reduction of greenhouse gas emissions. The artificial leather includes a bio urethane-containing skin surface layer which uses biomass-derived components extracted from vegetable components, a solvent-free bio urethane adhesive layer, and a bio fiber base layer. The layers are sequentially stacked to minimize the use of organic solvents and components that are harmful to the human body.

Eco-friendly artificial leather for interior of automobile and manufacturing method thereof

A method for manufacturing hybrid-natural leather having excellent appearance quality and good durability such as light resistance, water resistance, elongation and abrasion resistance is provided. Particularly, the fiber layer having a similar structure to the natural leather is introduced to the natural leather and the natural leather and the fiber layer are bonded and fused with each other under a specific condition to manufacture hybrid-natural leather having excellent durability while preventing wrinkles, stretching, and the like from being generated.

Method for manufacturing hybrid-nature leather having excellent appearance quality and durability

A method is provided for removing a volatile organic compound (VOC) contained in an artificial leather fabric and odor caused by the volatile organic compound by coating the artificial leather fabric with an adsorbent which reacts with a noxious substance containing the volatile organic compound (VOC); and immersing; washing; and drying the reacted artificial leather fabric. The method includes coating the adsorbent and immobilizing the volatile organic compound through a reaction, to prevent volatilization of the organic compound or reduce an amount thereof. Further, after the reaction between the artificial leather fabric and the adsorbent, the artificial leather fabric is washed, to remove the volatile organic compound immobilized on a surface of the fabric from the artificial leather.

Method for removing odor of artificial leather and artificial leather manufactured using the same

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.

Method for producing synthetic leather having air permeability

An ultra-light polyurethane artificial leather composition comprises a one-component type blocked polyurethane high solid resin of 100 parts per weight, a capsule-type hollow microsphere of 1 to 10 parts per weight, a curing agent of 1 to 10 parts per weight, and a high solid type toner of 1 to 20 parts per weight.

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.

Stainproofing method of fabric

The present invention relates to methods of forming an aqueous coating on a plastic sheet surface for vehicle interior equipment, comprising the steps of: coating the plastic sheet with a primary composition, the primary composition comprising chlorinated aqueous olefin resin; baking the resulting plastic sheet; coating the baked sheet with a secondary composition, the secondary composition comprising aliphatic urethane; and baking the resulting plastic sheet.

Method of aqueous coating of plastic sheet surface for vehicle interior equipment

The present invention relates to a thermoelastic polyolefin-based elastomer sheet composition for water based coating treatment, which comprises a partially crosslinked thermoelastic polyolefin-based elastomer resin, a non-crosslinked thermoelastic polyolefin-based elastomer resin, a polypropylene resin, an ethylene octene rubber resin, a linear low density polyethylene resin, polyethylene master batch containing a lubricant, and an inorganic filler, the composition being useful for vehicular inner parts (e.g., crash pad) due to its superior elongation, heat resistance, humidity resistance and molding property.
