Abstract
A sublimation donor has a first fabric enhancer that sublimates from the donor above a first temperature. That is followed by a second fabric enhancer that sublimates from the donor above a second temperature. Both the first and second temperatures are above 260° F. and the second temperature is at least 10° F. higher than the first temperature. Upon sublimation under a single pass processing unit, first and second catalysts trigger the first and second fabric enhancers to sublimate at the first and second temperatures, respectively.
Claims8
A method of operating a sublimation printing device, comprising:
- providing a donor for sublimation onto a receiver;
- juxtaposing at least a portion of the donor with at least a portion of the receiver;
- sublimating a first fabric enhancer from the donor above a first temperature;
- sublimating second fabric enhancer that sublimate from the donor above a second temperature, and wherein the first and second fabric enhancer is selected from the group consisting of:
- a finishing agent, a conditioning agent, a bleach, an antimicrobial substance, and a stain release agent, and
- wherein the second temperature is at least 10° F. higher than the first temperature and first and second catalysts that trigger the first and second fabric enhancers to sublimate at the first and second temperatures, respectively in one continuous process;
- and
- wherein the donor comprises first and second different colorants, each of which sublimates from the donor at a temperature of at least 260° F. and heating the donor from temperature (T1) to temperature (T2) for a period of time (S), defined by Q=M·(T1−T2)·S, wherein Q is energy in calories to sublimate the donor and M is the mass of the receiver.

- and
- wherein the donor comprises first and second different colorants, each of which sublimates from the donor at a temperature of at least 260° F. and heating the donor from 260° F. to 385° F. over a time period of at least 0.35 seconds.
