Abstract
A functional fabric is formed by bonding a polyester synthetic resin film mixed with carbon black fine particles to a fabric, in which the synthetic resin film is non-porous and has a thickness of 10 μm to 20 μm. The functional fabric is produced by producing a polyester synthetic resin film mixed with carbon black fine particles and bonding the synthetic resin film to a fabric, and the produced functional fabric is entirely or partially bonded to an inner wear or an intermediate clothes to produce clothing.
Claims7
A functional fabric comprising a fabric and a synthetic resin film bonded to the fabric, the synthetic resin film being made of polyethylene terephthalate (PET) and mixed with carbon black fine particles,
- the particle size range of carbon black fine particles is 80 nm to 500 nm, and
- the synthetic resin film is non-porous, and has a non-crystalline region formed by melting polyester chips containing the PET and 1% by weight of carbon black fine particles to form a melted polyester polymer, the melted polyester polymer forming a sheet-like film by a T-die method, passing the sheet-like film of the melted polyester polymer through a cooling roll at 20° C. to 25° C. to produce a thinner film coat by the T-die method, and cooling the melted polyester polymer at the glass transition temperature or lower to thereby create the non-crystalline region in the synthetic resin film, and is adhered to the fabric by dots of an adhesive resin.
A method for producing a functional fabric, the method comprising:
- producing a synthetic resin film being made of polyethylene terephthalate (PET) and mixed with carbon black fine particles;
- bonding the synthetic resin film to a fabric by dots of an adhesive resin, at the producing a non-porous synthetic resin film, with the particle size range of carbon black fine particles is 80 nm to 500 nm, and the synthetic resin film's thickness of 10 μm to 20 μm;
- and
- forming a non-crystalline region by melting polyester chips containing the PET and 1% by weight of carbon black fine particles to form a melted polyester polymer forming a sheet-like film by a T-die method, passing the sheet-like film of the melted polyester polymer through a cooling roll at 20° C. to 25° C. to produce a thinner film coat by the T-die method to thereby create non-crystalline regions in the synthetic resin film, and cooling the melted polyester polymer at the glass transition temperature or lower.
A clothing comprising a functional fabric including a fabric and a synthetic resin film bonded to the fabric by dots of an adhesive resin, the synthetic resin film being made of polyethylene terephthalate (PET) and mixed with carbon black fine particles,
- the particle size range of carbon black fine particles is 80 nm to 500 nm;
- the synthetic resin film is non-porous, and has a thickness of 10 μm to 20 μm and a non-crystalline region formed by melting polyester chips containing the PET and 1% by weight of carbon black fine particles to form a melted polyester polymer, the melted polyester polymer forming a sheet-like film by a T-die method, passing the sheet-like film of the melted polyester polymer through a cooling roll at 20° C. to 25° C. to produce a thinner film coat by the T-die method to thereby create non-crystalline regions in the synthetic resin film, and cooling the melted polyester polymer at the glass transition temperature or lower;
- and
- an inner wear or an intermediate clothes to which the functional fabric is entirely or partially bonded.
