The present invention provides: a rubber composition that is attached as a thin film to a urethane layer so as to be coatable, and thus can be adhered to the surface of a rubber material in a no-sew manner by being melted together with the urethane layer; and a method for manufacturing the film. To this end, the present invention is characterized in that a solute material, including a solid rubber raw material and at least 10 parts by weight of an acrylonitrile butadiene rubber (NBR)-based resin with respect to 100 parts by weight of the solid rubber raw material, at least 50 parts by weight of a bonding additive per 100 parts by weight of the solute material, and at least 150 parts by weight of a solvent material per 100 parts by weight of the solute material are mixed to form a liquid state.
The present invention relates to a continuous printing apparatus using a vacuum suction roller, and it is to provide a continuous printing apparatus and method using a vacuum suction roller capable of reducing costs and improving productivity by continuously printing on the surface of a woven fabric using the vacuum suction roller.
The present invention relates to a powder puff sheet having alcohol resistance, and a manufacturing method therefor. According to the present invention, a powder puff sheet simultaneously having improved flexibility and alcohol resistance is provided.
The present invention relates to a multicolored thread having multiple coating layers obtained by coating a single yarn with multiple layers so as to exhibit various color impressions. The present invention is advantageous in that various colors can be implemented by a single yarn, and, when the same is used for weaving, a distinctive aesthetic appearance can be provided. The present invention is also advantageous in that, by forming multiple urethane coating layers, the same has better resistance to wear than that of the yarn, the mechanical characteristics and durability can be improved, and excellent thermal molding characteristics and bonding can be implemented.

The present invention provides: a film having high dew-suppressive capabilities in a low-temperature state and excellent moisture-permeability in a high temperature state; and a moisture permeable waterproof fabric using this film, which is suitable for precipitation (snow) use, sports use, outdoor use, work use, and the like. This moisture permeable waterproof film is characterized by: containing a polyurethane resin modified with an acrylic resin; and having an LCST (lower critical solution temperature).
The present invention relates to a method for continuously manufacturing a sponge sheet for a powder puff, comprising: a coating step for coating a fabric using a mixed solution; a solidification step for solidifying the coated fabric, which has been coated with the mixed solution, in a solidification bath; a cleaning step for cleaning the fabric, which has passed through the solidification bath, in a cleaning bath; a coated fabric manufacturing step for carrying out a heat dry step for drying the fabric which has passed through the cleaning bath and then winding the fabric; a coated fabric buffing step for buffing the coated fabric, which has passed through the coated fabric manufacturing step, using a buffing roller and then winding the coated fabric; and a separation step for separating the fabric from the buffed and coated fabric and winding the fabric separately from a sponge sheet for a powder puff. Accordingly, there are provided effects that a sponge sheet for a powder puff can be continuously manufactured during a process time within a day, and a buffing method is selected instead of a slicing method so that processing is possible even though the thickness becomes smaller, thereby manufacturing various sizes of sponge sheets for a powder puff.
