Methods of assembling apparel products having imine adhesives
Embodiments provide methods of assembling apparel products. The methods include applying a composition to a portion of a major component of the apparel product or a portion of a minor component of the apparel product. The methods include coupling the portion of the minor component with the portion of the major component via the composition. 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 via an adhesive. The methods include converting the composition to form the adhesive and the apparel product. The adhesive includes a material having an imine bond or an iminium bond.
1. A method of assembling an apparel product, comprising:
applying a pH reversible adhesive to a portion of a major component of the apparel product or a portion of a minor component of the apparel product, the pH reversible adhesive having cross-linked imine bonds or iminium bonds, wherein the pH reversible adhesive is generated by reacting a first component comprising one or more aldehyde groups or one or more ketone groups with a second component comprising one or more amine groups to form the pH reversible adhesive having cross-linked imine bonds or iminium bonds;
coupling the portion of the minor component to the portion of the major component via the pH reversible adhesive, the major component forming a base portion of the apparel product and configured to be supported and worn at least partially over a portion of a wearer, and the minor component forming a secondary portion configured to be coupled to the major component with the pH reversible adhesive; and
curing the pH reversible adhesive to form the apparel product, wherein the pH reversible adhesive is configured to enable separation of the major component from the minor component by submerging the apparel product in a solution having a particular pH value for a particular period of time.
2. The method of claim 1 , wherein said applying the pH reversible adhesive comprises applying the pH reversible adhesive by a heat gun, printing, spraying, painting, dipping, roll on, screen printing, or combinations thereof.
3. The method of claim 1 , wherein the pH reversible adhesive comprises polyethyleneimine.
4. The method of claim 1 , wherein the apparel product is selected from the group consisting of a shirt, a pant, a skirt, a coat, a dress, a sweater, a body suit, and combinations thereof.
5. The method of claim 1 , wherein the major component comprises a material selected from the group consisting of a polyester, a polyamide, a cotton, mixtures thereof, and combinations thereof.
6. The method of claim 1 , wherein the pH reversible adhesive has a T-peel strength of about 5 N/cm-width to about 100 N/cm-width.
7. The method of claim 1 , wherein the pH reversible adhesive is applied such that a thickness of the pH reversible adhesive is about 0.025 mm to about 5 mm.
