Method for removing colorant and elastomeric polymers from mixed textile feedstock for recycling

A method for separating components of a mixed textile feedstock, wherein the mixed textile feedstock comprises a colorant, elastomeric polymers and one or more other textile materials, the method comprising:

• extracting at least some of the colorant from the mixed textile feedstock using a first extraction process resulting in an intermediate textile feedstock, wherein the first extraction process comprises contacting the mixed textile feedstock to a first heated solution comprising a first solvent;
• and
• extracting at least some of the elastomeric polymers from the intermediate textile feedstock using a second extraction process, resulting in a purified textile product that excludes the at least some of the colorant and the at least some of the elastomeric polymers, wherein the second extraction process comprises contacting the intermediate textile feedstock to a second heated solution comprising a second solvent different from the first solvent, wherein the first solvent and the second solvent are selected from the first group consisting of an alcohol, an ether, an ester, and a ketone.

• extracting at least some of the colorant from the textile feedstock using a first extraction process resulting in an intermediate textile feedstock, wherein the first extraction process comprises contacting the mixed textile feedstock to a solution comprising a solvent in association with heating the solution to a first temperature, wherein the solvent comprises a cyclic ketone;
• and
• extracting at least some of the elastomeric polymers from the intermediate textile feedstock using a second extraction process, resulting in a purified textile product that excludes the at least some of the colorant and the at least some of the elastomeric polymers, wherein the second extraction process comprises contacting the intermediate textile feedstock to the solution in association with heating the solution to a second temperature higher than the first temperature.
