Abstract
The present invention relates to a threadlike adhesive body including a threadlike core material and an adhesive layer covering a circumferential surface of the core material in a longitudinal direction, in which the core material contains a recycled resin, and a coverage rate of the circumferential surface with the adhesive layer is 50% or more.
Claims9
A threadlike adhesive body comprising:
- a threadlike core material and an adhesive layer configured to cover a circumferential surface of the core material in a longitudinal direction,
- wherein the core material contains a recycled resin, and
- a coverage rate of the circumferential surface with the adhesive layer is 50% or more.
A method for producing a threadlike adhesive body including a threadlike core material and an adhesive layer configured to cover a circumferential surface of the core material in a longitudinal direction, comprising
- a step of forming the adhesive layer by applying a coating liquid to the circumferential surface of the core material in the longitudinal direction,
- wherein the coating liquid has a solution viscosity of 0.03 to 6 Pa s under a condition of a shear rate of 100 (1/s) and a solution viscosity of 2 to 140 Pa s under a condition of a shear rate of 0.1 (1/s).
A method for producing a threadlike adhesive body including a threadlike core material and an adhesive layer configured to cover a circumferential surface of the core material in a longitudinal direction, comprising
- a step of forming the adhesive layer by applying a coating liquid to the circumferential surface of the core material in the longitudinal direction,
- wherein a tension of the core material during coating is 6 mN/dtex or less.
