Description
- 1. Field of the Invention
- The present invention relates to an artificial leather and a method for making the same, and in particular, to a polyester-series artificial leather and a method for making the same.
- 2. Description of the Related Art
- In the conventional method for making an artificial leather, a nonwoven fabric is coated with a polyurethane (PU) and then is extruded, so that the PU infiltrates the nonwoven fabric. Finally, the nonwoven fabric passes through a coagulative water bath, allowing the Dimethyl Formamide (DMF) solvent in the PU to replaced with the water, so that the PU will be solidified, thereby producing an artificial leather. Defects of this method lie in that, a large amount of DMF solvent needs to be consumed, and a large amount of waste water is produced after the washing process. The recycling process of the waste water is also rather complicated. Moreover, in the artificial leather, the PU resin layer cannot be separated from the nonwoven fabric so that the leather cannot be recycled or reused because of the difference in materials. As a result, it will create a large amount of waste, and has a negative effect on the environment.
- Therefore, it is necessary to provide a creative and progressive artificial leather and a method for making the same to solve the foregoing problems.
- The present invention provides a method for making an artificial leather, including: (a) providing a Thermoplastic Polyester Elastomer (TPEE); (b) enabling the TPEE to form a molten TPEE; and (c) enabling the molten TPEE to form a TPEE resin layer, and then attaching the TPEE resin layer on a polyester fiber substrate by using a chilling roller, so as to form an artificial leather.
- The present invention also provides a method for making an artificial leather, including: (a) providing a TPEE; (b) adding a foaming agent to the TPEE to form a first raw material, and then heating the first raw material, so that the first raw material forms a molten foamed TPEE, where the weight of the foaming agent is 1% to 10% of the weight of the TPEE; (c) heating a second raw material, so as to form a molten second material; (d) forming a bi-layer structure from the molten foamed TPEE and the second raw material, where the bi-layer structure has a foamed TPEE resin layer and a second raw material layer; and (e) attaching the bi-layer structure to a polyester fiber substrate, so as to form an artificial leather.
- The present invention further provides an artificial leather, including a polyester fiber substrate and a foamed TPEE resin layer, wherein the polyester fiber substrate has a plurality of polyester fibers, the foamed TPEE resin layer is adjacent to the polyester fiber substrate, and the material thereof is TPEE.
- In the present invention, the method for making the artificial leather does not require any solvent, and in comparison to the conventional process, this method does not produce any waste water, thereby protecting the environment. Additionally, the materials of all layers of the artificial leather are polyester types. Therefore, the method of disposal for the artificial leather is to entirely and directly melt the artificial leather for recycling and reuse, thereby protecting the environment, too.
- The invention will be described according to the appended drawings in which:

raw material 12 is heated to form amolten TPEE 14. In this embodiment, the firstraw material 12 is heated by anextruder 13 and themolten TPEE 14 is extruded by theextruder 13. Theextruder 13 has a flow path (not shown), for the firstraw material 12 to flow. Additionally, different temperatures are set at different positions of the flow path. For example, the flow path can be divided into five sections, and the five sections are set to be 200° C., 220° C., 240° C., 250° C., and 260° C., respectively. - Afterwards, film-forming the
molten TPEE 14, so as to form aTPEE resin layer 16. In this embodiment, the flow path of theextruder 13 is connected with a T-die 15. Furthermore, film-forming is performed to themolten TPEE 14 by using the T-die 15, so as to form theTPEE resin layer 16. Then theTPEE resin layer 16 is attached to apolyester fiber substrate 17, so as to form anartificial leather 2. In this embodiment, thepolyester fiber substrate 17 is formed from a plurality of polyester fibers, and theTPEE resin layer 16 and thepolyester fiber substrate 17 are pressed by achilling roller 18, so as to form theartificial leather 2.

6. The method according to claim 4 , wherein in step (c), the second raw material is a TPEE; in step (d), the second raw material layer of the bi-layer structure is a non-foamed TPEE resin layer; in step (e), the bi-layer structure and the polyester fiber substrate are pressed by using a chilling roller, so as to form the artificial leather, wherein the foamed TPEE resin layer is in contact with the polyester fiber substrate.
7. The method according to claim 4 , wherein in step (c), the second raw material is a polyethylene terephthalate (PET) hotmelt adhesive; in step (d), the second raw material layer of the bi-layer structure is a PET hotmelt adhesive layer; in step (e), the bi-layer structure is attached to the polyester fiber substrate after being hot pressed, so as to form the artificial leather, wherein the PET hotmelt adhesive layer is adhered to the polyester fiber substrate.
8. An artificial leather, comprising:
a polyester fiber substrate, having a plurality of polyester fibers; and
a foamed Thermoplastic Polyester Elastomer (TPEE) resin layer, adjacent to the polyester fiber substrate, wherein the material thereof is TPEE.
9. The artificial leather according to claim 8 , wherein the porosity of the foamed TPEE resin layer is in the range of 30% to 80%, and the foamed TPEE resin layer is adhered to the polyester fiber substrate.
10. The artificial leather according to claim 8 , further comprising a non-foamed TPEE resin layer, located on the foamed TPEE resin layer, wherein the material thereof is the TPEE, and the foamed TPEE resin layer is in contact with the polyester fiber substrate.
