Abstract

The present disclosure relates to an innovative leather and a manufacturing method thereof. The innovative leather includes a Polyester substrate, a Polyester adhering layer, and a Polyester surface layer. The Polyester adhering layer is disposed on the Polyester substrate. The Polyester surface layer is disposed on the Polyester adhering layer. All materials of the innovative leather of the present disclosure are the same Polyester materials, thus the innovative leather of the present disclosure can be recycled after the innovative leather of the present disclosure is used. The innovative leather of the present disclosure has recycling benefit.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An innovative leather, comprising:
 a Polyester substrate;   a Polyester adhering layer, disposed on the Polyester substrate; and   a Polyester surface layer, disposed on the Polyester adhering layer.   
     
     
         2 . The innovative leather of  claim 1 , wherein the Polyester substrate is a PET (Polyethylene Terephthalate) material, a TPEE (Thermoplastic Polyether Elastomer) material or a PBT (Polybutylene Terephthalate) material. 
     
     
         3 . The innovative leather of  claim 1 , wherein the Polyester adhering layer is a PET (Polyethylene Terephthalate) material, a TPEE (Thermoplastic Polyether Elastomer) material or a PBT (Polybutylene Terephthalate) material. 
     
     
         4 . The innovative leather of  claim 3 , wherein the Polyester adhering layer has a weight of 50-400 g/m 2  and a density of 0.2-0.8 g/cm 3 . 
     
     
         5 . The innovative leather of  claim 1 , wherein the Polyester surface layer is a PET (Polyethylene Terephthalate) material, a TPEE (Thermoplastic Polyether Elastomer) material or a PBT (Polybutylene Terephthalate) material. 
     
     
         6 . The innovative leather of  claim 5 , wherein the Polyester surface layer has a weight of 50-400 g/m 2  and a density of 0.5-0.9 g/cm 3 . 
     
     
         7 . The innovative leather of  claim 1 , wherein The Polyester surface layer comprises a thermoplastic Polyester material and a thermoplastic Polyester recycled material, the thermoplastic Polyester material and the thermoplastic Polyester recycled material are mixed in a weight ratio of 75%:25% to 100%:0%. 
     
     
         8 . A manufacturing method of an innovative leather, comprising:
 providing a Polyester substrate;   melt-blowing a Polyester adhering layer onto the Polyester substrate;   melt-blowing a Polyester surface layer onto the Polyester adhering layer; and   thermally compressing and bonding the Polyester substrate, the Polyester adhering layer and the Polyester surface layer.   
     
     
         8 . The manufacturing method of  claim 8 , wherein the step of melt-blowing the Polyester adhering layer further comprises using first thermoplastic Polyester particles having a melting point of 120-150° C. 
     
     
         10 . The manufacturing method of claim  9 , wherein the first thermoplastic Polyester particles are PBT particles or TPEE particles. 
     
     
         11 . The manufacturing method of  claim 8 , wherein the step of melt-blowing the Polyester surface layer further comprises using second thermoplastic Polyester particles having a melting point of 130-170° C. 
     
     
         12 . The manufacturing method of  claim 11 , wherein the second thermoplastic Polyester particles are TPEE particles. 
     
     
         13 . The manufacturing method of  claim 11 , wherein the step of melt-blowing the Polyester surface layer further comprises using thermoplastic Polyester recycled particles, the second thermoplastic Polyester particles and the thermoplastic Polyester recycled particles are mixed in a weight ratio of 75%:25% to 100%:0%. 
     
     
         14 . The manufacturing method of  claim 8 , wherein in the thermally bonding step, a temperature is 140° C.-160° C. 
     
     
         15 . The manufacturing method of  claim 8 , wherein in the step of melt-blowing the Polyester adhering layer, a melt-blowing distance is 250-350 mm. 
     
     
         16 . The manufacturing method of  claim 8 , wherein in the step of melt-blowing the Polyester surface layer, a melt-blowing distance is 150-250 mm.
