A process is disclosed for the making of a decorative carpet through the use of sublimable dyes. A shading effect is secured through the use of air flow control sheets that affect the flow of air through a transfer sheet and a carpet product adjacent thereto. By lessening air flow, the intensity of dye being transferred is also lessened so that shades of a certain color can be secured.

Process for shading during the vapor phase dyeing of carpet

A process for the preparation of a metal halide-amide reaction product, useful in the preparation of metal-modified amide-aldehyde polymers, which comprises (1) reacting in a water-immiscible inert liquid medium a metal halide with at least one amide having at least two replaceable hydrogens to obtain a reaction product therebetween; (2) hydrolyzing the reaction product obtained in step (1) above with water to form an aqueous solution of the reaction product; (3) partially neutralizing the aqueous solution of the reaction product obtained in step (2) with a bicarbonate, and (4) recovering the metal halide-amide reaction product obtained.

Process for producing metal halide-amide reaction product

A transfer sheet is printed with inks containing sublimable dyes. A carpet having face fibers and a backing is prepared. The inked surface of the transfer sheet and the carpet are positioned adjacent the openings on opposite sides of a honeycomb structure. Heated air is applied to the transfer sheet to sublime the dyes in the ink and to transfer the sublimed dyes from the carrier, through the passageways of the honeycomb structure, to the carpet. The fibers of the carpet are thereby dyed.

Method of no-contact printing of carpet with a transfer sheet

The invention is directed to a transfer sheet for use with sublimable dye. It is used in a dry transfer printing operation. An ideal transfer sheet must have certain porosity, strength, and other structural characteristics to permit its use in a manufacturing operation wherein a continuous printing operation is carried out.

Transfer sheet

A pattern is placed on a porous transfer sheet by the use of sublimable dyes. Carpet face yarns are tufted into a backing material. The transfer sheet is placed adjacent the back of the carpet on the side of the carpet opposite from the carpet face yarns. Heated air causes the sublimable dye to move from the transfer sheet, through the carpet backing to the face yarns of the carpet to provide the dye pattern on the face yarns.
