Abstract
A shoe upper is non-yellowed by using a film. The film is covered on a leather. The film has the function of discoloration and has a low density.
Description
- The present invention relates to a footwear; more particularly, relates to a film layer adhered to a leather layer for obtaining a shoe upper with discoloration.
- A prior art is claimed in a US patent, U.S. Pat. No. 6,739,076, “Artificial leather shoe and artificial leather suited therefore”, comprising a shoe upper and a shoe sole. The shoe upper orderly comprises a first substrate layer, an adhesive layer and a second substrate layer. The first substrate layer comprises a first entangled nonwoven fabric and a first elastomeric polymer impregnated in the first entangled nonwoven fabric, where the first entangled nonwoven fabric comprises ultrafine fibers having a fineness of not more than 0.01 decitex. The second substrate layer comprises a second entangled nonwoven fabric and a second elastomeric polymer impregnated in the second entangled nonwoven fabric, where the second entangled nonwoven fabric comprises fibers having a fineness of not less than 0.05 decitex. The outer surface of the first substrate layer forms an exterior surface of the shoe upper. The shoe sole is fixedly bonded to a portion of the shoe upper with an adhesive. At the portion of the shoe upper that is fixedly bonded to the shoe sole, the first substrate layer and the adhesive layer have been substantially removed such that the second substrate layer is directly bonded to the shoe sole with the adhesive. The outer surface of the first substrate layer is at least a partially napped outer surface or is at least partially covered with a macromolecular elastomer. A bond peel strength of the second substrate layer is not less than 7.0 kg/25 cm. A ratio of the bond peel strength of the second substrate layer to a bond peel strength of the first substrate layer is not less than 1.5. In addition, a color difference between the first substrate layer and the adhesive layer, and a color difference between the second substrate layer and the adhesive layer, are both not less than 2.0.
- Although the above prior art constructs an artificial leather shoe, the layers of the shoe upper is unstable because they are bond by using adhesive. Besides, without a protection layer on the shoe upper, the shoe upper may get dirty easily and become yellowed. Hence, the prior art does not fulfill users' requests on actual use.
- The main purpose of the present invention is to obtain a discoloration through a film layer adhered to a leather layer.
- To achieve the above purpose, the present invention is a footwear having a non-yellowing film, comprising a shoe sole and a shoe upper, where the shoe upper is obtained by adhering a film layer and a leather layer through a high frequency waving; the leather layer is made of an artificial leather or a fabric; the film layer is made of a fluid-type material mixture of a Styrene-Ethylene/Butylene-Styrene (SEBS) block copolymer, a Polyolefin Elastomer (POE), an Ethylene-Vinyl Acetate (EVA) and a slip agent with different ratios; the mixture is extruded to obtain a pellet-type material; the pellet-type material is extruded through a T-die to obtain a raw material; and the film is made of the raw material through a two rolls mill. Accordingly, a novel footwear having a non-yellowing film is obtained.

Thus, a footwear having a non-yellowing film is obtained. - Please refer to
FIG. 2 , which is a view showing the film layer. As shown in the figure, thefilm layer 122 is obtained by mixing ingredients of a 5˜50% of Styrene-Ethylene/Butylene-Styrene (SEBS)block copolymer 1221, a 30˜80% of Polyolefin Elastomer (POE) 1222, a 5˜15% of Ethylene-Vinyl Acetate (EVA) 1223 and aslip agent 1224, where theslip agent 1224 is a wax or an amine; the density of thefilm layer 122 is smaller than 1; and the thickness of thefilm layer 122 is between 0.17 millimeters (mm) and 2.0 mm. - When making the
film layer 122, the following steps are included: - Step (a): Please refer to
FIG. 3 , which is a view showing step (a) for making the film layer. As shown in the figure, a 45% ofSEBS block copolymer 1221 of G1651 by KRATON Polymers, a 40% ofPOE 1222 of DF110 by Mitsul Elastomers Singapore, a 15% of EVA of UE629 by USI Corporation, and a slip agent are well mixed to obtain a fluid-type material 122 a by a slicing force thoughtwin screws 31 of amixer 3 under 180˜250 Celsius degrees (° C.). Furthermore, when mixing the material of thefilm layer 122 in themixer 3, a required pigment can be added for thefilm layer 122 to obtain a required color. - Step (b): Please refer to
FIG. 4 , which is a view showing step (b). As shown in the figure, after the mixing, the fluid-type material 122 a is extruded withtwin screws 41 of anextruder 4 under 180° C. to obtain a pellet-type material 122 b. - Step (c): Please refer to
