Method of producing decorative vertical louver window covering material and decorative vertical louver material so produced

A method for producing an improved embossed wall or window covering product, the method comprising:

• (a) applying a heat stabilized, pigmented, solvent soluble, thermoplastic resin composition to one planar surface of an heat set nonwoven polyester web, wherein said composition includes:
• i) low molecular weight homopolymer polyvinyl chloride resin,
• ii) copolymer polyvinyl chloride/vinyl acetate resin,
• iii) solvent,
• iv) plasticizer,
• v) pigment predispersed in a vinyl compatible binder system with solvent and stabilizer,
• vi) heat stabilizer,
• vii) antistat, and
• viii) light stabilizer;
• (b) heating the web to remove substantially all of the solvents and cure the thermoplastic resins;
• (c) cooling the web;
• (d) applying a second heat stabilized, pigmented, solvent soluble, thermoplastic resin composition to the opposite planar surface of the nonwoven web;
• (e) heating the web a second time to remove substantially all of the solvents and cure the thermoplastic resin of said second composition;
• (f) preheating the twice-cured web to a temperature of about 275.degree. F.;
• (g) further heating the twice-cured web just prior to pressing the web between an embossing roll and a rubber back-up roll having a Shore A hardness of at least 90 to emboss a pattern into the web, wherein said further heating is at a temperature ranging from about 290.degree. F. to a temperature that is insufficient to melt the cured resin solids and wherein said back-up roll is being cooled during said embossing;
• and
• (h) rapidly cooling the embossed web.

A method for producing an improved wall or window covering product, the method comprising:

• (a) applying a thermoplastic resin dissolved in a solvent to a heat set non-woven polyester web;
• (b) curing the thermoplastic resin;
• and
• (c) embossing the web against a rubber back-up roll having a Shore A hardness of at least about 90 to produce a predetermined embossed pattern in the web.
