The present invention is directed to a heat-activated adhesive patch with integral attachment device wherein said patch can be permanently attached to an article of clothing or other article made of natural or synthetic substrate by means of using heat and pressure, whereby said patch with integral attachment device can be used to attach or hang an article or device from said heat-activated patch using said integral attachment device.

A method for producing an adhesive layer composition for producing a cooling sheet including a backing layer, an adhesive layer, and a liner layer, the method comprising the step of:

mixing a composition to be mixed containing water, an alum, sodium edetate, a polyacrylic acid, and a neutralized polyacrylic acid such that a mixing temperature becomes 5 to 23° C., to obtain an adhesive layer composition, wherein

in the composition to be mixed,

a content of the water is 69 to 938.24% by mass relative to a total mass of the composition to be mixed,

a content of the alum is 0.18 to 0.42% by mass relative to the total mass of the composition to be mixed,

a content of the sodium edetate is 0.08 to 0.18% by mass relative to the total mass of the composition to be mixed, and

a mass ratio between the content of the alum and the content of the sodium edetate (the content of the alum:the content of the sodium edetate) is 1:1 to 5.25:1.

An object of the invention is to provide a moisture-curable polyurethane resin composition containing a biomass raw material and having excellent adhesiveness to a fabric (particularly, a water-repellent fabric) and excellent film strength. The invention provides a moisture-curable polyurethane hot-melt resin composition containing: a urethane prepolymer (i) having an isocyanate group, which is a reaction product of a polyol (A) and a polyisocyanate (B), the polyol (A) containing a polyester polyol (a1) containing, as raw materials, a biomass-derived polybasic acid (x) and a biomass-derived glycol (y), and another polyester polyol (a2). In addition, the invention provides an adhesive containing the moisture-curable polyurethane hot-melt resin composition.

A laminate for use in a process for strengthening a selected area of a raw textile or manufactured textile product to enhance properties and performance. The process comprising the steps of applying a laminate trimmed to match the selected. area, then placed on the textile and heated in a hot press. The laminate can be comprised of a polymer film and a nonsolvent adhesive. The polymer film can be tailored from a blend of hard acrylic and tough poly-urethane to adjust for rigidity and strength. The adhesive can he a hot melt or pressure sensitive types as well as any type that provides a secure adhesion.

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 with an adhesive. The methods include converting the composition to the adhesive. The adhesive including a material having a disulfide bond.
