Time and temperature additive scheduling
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.
1. 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 (T 1 ) to temperature (T 2 ) for a period of time (S), defined by Q=M·(T 1 −T 2 )·S, wherein Q is energy in calories to sublimate the donor and M is the mass of the receiver.
2. The method of claim 1 wherein at least one of the catalysts is selected from the group consisting of olefins, sulfonium compounds, polyaniline compounds, and tetra-amido macrocyclic ligands.
3. The method of claim 1 wherein the first and second temperatures differ by at least 20° F.
4. The method of claim 1 wherein the first and second temperatures differ by at least 30° F.
5. The method of claim 1 , further comprising sublimating a donor onto the receiver to produce a fabric wherein the fabric contains visually detectable amounts of both first and second colorants and the fabric further contains a detectable amount of the first fabric enhancer.
6. The method of claim 5 , wherein the first and second colorants are sublimated onto the fabric in a continuous disposition.
7. The method of claim 5 , wherein the fabric contains a detectable amount of the second fabric enhancer.
8. 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 a 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 260° F. to 385° F. over a time period of at least 0.35 seconds.
