Abstract

Embodiments provide methods of disassembling an apparel product. The methods include exposing an adhesive of the apparel product to electromagnetic energy. The adhesive is disposed at least partially between a major component and a minor component of the apparel product. The adhesive includes a polymer having a cyclodextrin moiety bonded to an azobenzene moiety. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.
