- the step of laminating the skin film layer and the adhesive layer with the base substrate layer is a step of laminating the adhesive layer on the base substrate layer and laminating the skin film layer thereon, applying heat and pressure.
- the heat and pressure to be applied depending on the melting point of the adhesive layer may vary, and may be combined at a temperature of 120 ⁇ 170 °C, about 3.5 to 4.5 bar.
- the adhesive layer is laminated so as to contact the base substrate layer, and then laminated by applying heat and pressure.
- a method of manufacturing artificial leather using polyester includes preparing a skin film layer and an adhesive layer on a surface using polyester; The skin film layer and the adhesive layer may be laminated, and the foam may be inserted between the skin film layer and the adhesive layer, and the base substrate layer may be laminated and laminated to contact the adhesive layer.
- the steps of preparing the skin film layer and the adhesive layer using the polyester and laminating the base substrate layer so as to contact the adhesive layer are as described above.
- the step of laminating the skin film layer and the adhesive layer and inserting the foam between the skin film layer and the adhesive layer is a step for forming the foam layer to improve the elasticity of the artificial leather.
- a foam in the form of a capsule may be inserted between the skin film layer and the adhesive layer, and the foam may be foamed during extrusion in the foaming step to form a foam layer.
- the foam should be adjusted in the amount and composition of the foam so that the thickness of the foam layer is 100 ⁇ 300 ⁇ m, density 0.5 ⁇ 0.8g / cm 3 and the foam may be a foam of polyester material.
- the foam can be selected from the material that the volume is best expanded at 150 ⁇ 250 °C.
- Artificial leather manufacturing method using a polyester according to another embodiment of the present invention forms a foam layer, it is inserted between the skin film layer and the adhesive layer. That is, the foam may be combined by forming a film layer with a foaming agent, rather than forming a foaming layer in the foaming step.
- the present invention can be applied to car interiors, furniture, upper materials for interior materials and the like.
