The present invention relates to a threadlike adhesive body including a threadlike core material and an adhesive layer covering a surface of the core material in a longitudinal direction, in which the core material is a multifilament yarn including two or more filaments obtained by intertwining or twisting a filament containing a recycled resin and a filament not containing a recycled resin.

Apparatuses, methods, and systems are disclosed for an adhesive including an activated portion and an unactivated portion. The adhesive is interposed between and binds the first substrate to a second substrate. The unactivated portion includes moisture, and the activated portion is activated to adhere in response to the removal of moisture. Similarly, the unactivated portion of the adhesive may be activated in response to the removal of moisture, removal of air, applying radiation, heating, and/or catalyzing a functional group.
