Abstract
A bright-finish metal-coated fabric having a metal layer directly deposited on the fabric. A fabric, selected to be capable of flattening or polishing under heat and pressure, is pressed against a heated surface and is then vacuum metalized. In a preferred embodiment, a thermoplastic fabric is flattened against a hot roll in a calender press under high pressure, and aluminum is then vapor-deposited.

A method of producing a fabric having a bright-finish metallic appearance, comprising:
- (a) providing a fabric comprising fibers which can be flattened by heat or pressure,
- (b) flattening or polishing a surface of said fabric by pressing it against a smooth heated surface, and
- (c) then depositing a reflective metal material directly onto the flattened or polished surface.
A method of producing a thermoplastic fabric having a bright-finish metallic appearance, comprising:
- (a) providing a fabric comprising yarns including a thermoplastic material,
- (b) heating a hard roll of a calendering press to a temperature sufficient at least slightly to soften a surface of the fabric upon contact with the roll,
- (c) calendering said fabric under high pressure between said heated hard roll and a second roll of the press, and then
- (d) depositing a metal layer on the surface of the fabric contacted by said heated roll.
A method of producing a fabric having a bright-finish metallic appearance, comprising:
- (a) providing a fabric comprising thermoplastic material,
- (b) selecting a calendering press having a hard metal first roll and a second roll,
- (c) heating said first roll to a temperature of at least approximately 250.degree. F.,
- (d) then calendering said fabric between said rolls at a pressure of at least approximately 21/2 tons per foot, and then
- (e) depositing a reflective metal layer at least on the fabric surface contacted by the first roll.
