Abstract
A process for dyeing a thermoplastic elastomeric substrate comprising immersing the substrate into a dye system comprising at least one metal complex dye and a solvent system comprising water and an organic solvent. The organic solvent may be soluble, partially miscible with water or insoluble or nearly insoluble in water. In particular, the substrate is an inflated bladder such as an airbag used in athletic shoes.
Claims25
A process for dyeing a thermoplastic elastomeric substrate comprising immersing the substrate in a heated dyeing system for a time sufficient to allow an amount of dye to diffuse into the substrate wherein the heated dyeing system comprises at least one metal complex dye and a solvent system comprising water, wherein the temperature of the heated dye solution is at least about 30 to about 70° C. wherein the thermoplastic elastomeric substrate comprises thermoplastic polyurethane or polyether block amide and wherein said metal complex dye is an acid solvent dye selected from the group consisting of Bezanyl Black, Bezanyl Red, Bezanyl Yellow, Orasol Black, Orasol Blue GN, Orasol Red G, Orasol Yellow 2GLN, Isolan Blue SR-R, Isolan Grey SP-G, Isolan Red SP-G, Isolan Yellow SP-2RL, Pylam Solvent Blue, Pylam Solvent Red, Pylam Solvent Yellow, Resofast Blue, Resofast Orange and Resofast Yellow.
A process for dyeing an inflated bladder comprising immersing at least a portion of the inflated bladder in a heated dyeing system for a time sufficient to allow an amount of dye to diffuse into the bladder wherein the heated dyeing system comprises at least one metal complex dye and a solvent system comprising water;
- wherein the temperature of the heated dye solution is at least about 30 to about 70° C. wherein the bladder comprises themoplastic polyurethane or polyether block amide and wherein the metal complex dye is selected from the group consisting of Bezanyl Black, Bezanyl Red, Bezanyl Yellow, Orasol Black, Orasol Blue GN, Orasol Red G, Orasol Yellow 2GLN, Isolan Blue SR-R, Isolan Grey SP-G, Isolan Red SP-G, Isolan Yellow SP-2RL, Pylam Solvent Blue, Pylam Solvent Red, Pylam Solvent Yellow, Resofast Blue, Resofast Orange and Resofast Yellow.
