Abstract
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.
Claims3
A process for forming a printed through color sheet structure comprising the steps of:
- (a) forming a non-woven or open cell foam porous base material,
- (b) preparing a transfer sheet with a sublimable dye thereon
- (c) transfer printing the sublimable dye from the transfer sheet to the non-woven or open cell base material to secure complete penetration of the dye through the porous base material, and
- (d) applying pressure to the base material to compress the base material, consolidate its porous structure into a non-porous structure and fuse the porous base material into a non-porous sheet material of about 1/20 the thickness of that of the original thickness of the base material, thereby there is formed a through color sheet material.
