A porous material is printed with a sublimable dyestuff designed to achieve substantial pattern depth penetration. After the porous fabric has been printed it is consolidated by compression and fusion to a desired degree. This then provides a product which has a through color printed effect.

Through-color printing

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 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 process for flatting a glossy polyurethane surface is disclosed. The process involves the steps of forming a wear layer on a carrier member, such comprising a polyurethane-forming composition. The coated carrier member is then treated with vaporous water at a temperature below the dew point of the vaporous water so that a film of liquid water is deposited on the surface of the coating. The coating with the liquid water deposited thereon is then cured to a tack free state and then subjected to elevated temperatures where the curing of the polyurethane coating is completed.
