| 41 | Method for dyeing plastic lens | JP2000027745 | 2000-02-04 | JP2001214381A | 2001-08-07 | INUZUKA MINORU |
| PROBLEM TO BE SOLVED: To provide a method for dyeing a plastic lens capable of dyeing in a high concentration even in the plastic lens having a high refractive index, that is regarded as having a low dyeability. SOLUTION: This method for dyeing the plastic lens comprises performing the dyeing through a first step of pasting a dyeing material obtained by dissolving or dispersing a sublimating pigment as fine particles based on a color data controlled by an electronic computer on a substrate, a second step of opposing the pasted surface of the substrate pasted with the dyeing material with the plastic lens as non-contacting state in vacuum, a third step of dyeing the plastic lens by heating the substrate for sublimating the sublimating pigment and bringing the sublimed pigment in contact with the plastic lens and a fourth step of heating at >=90 deg.C and <=150 deg.C for fixing the sublimed pigment on the plastic lens dyed in the third process in an oven. | ||||||

| The present invention relates to a process for dyeing sheetlike textile materials with a dye, which comprises a concentrated dye system being applied in a total amount of 1% to 25% by weight, based on the textile material, to the textile material in two or more sub-steps and the dye being fixed on the textile material after each and every sub-step. | ||||||

| The processes and articles of the present invention use thermally stable and loft retentive polymers in sublimation printed flock fibers, which are particularly attractive for forming molded and heat laminated articles. The process and articles use high, medium and low energy dyes on the fibers. A preferred polymer for use in the fibers is poly(cyclohexylene- dimethylene terephthalate). The fibers are heat set before sublimation printing. | ||||||
