New description: [New technical field] This creation is about a shoe with yellowing resistance and low density film, especially for the film layer which is bonded to the leather layer to achieve yellowing resistance. [Previous technique #f] According to the general practitioners, such as the Republic of China Patent Gazette, Announcement No. 526303, "artificial leather shoes and artificial leather suitable for this", according to the fine fiber network containing less than 0.01 dtex (decitex) a base layer (A) of an elastic polymer in a non-woven fabric, a binder layer (B), and a base layer of an elastic polymer in a nonwoven fabric comprising a fiber of 〇.05 dtex or more ( a sequential laminated layer of c), the upper material and the sole material formed by placing the side of the laminated body (A) layer on the outer side with a cement; on the bonding portion of the upper material and the sole material , substantially removing the (A) layer and the (b) layer of the upper material, and directly fixing the (C) layer and the sole material with a cement; the (A) layer of the composite non-woven fabric is composed of poly The ultrafine fiber bundle of the amine is formed such that at least a portion of the outer surface thereof is fuzzed, or a resin layer of the polymer elastomer is laminated on the outer surface, and the adhesive peel strength of the substrate (c) is 7.0kg/2.5cm or more, and the base (A) layer is bonded to the peel strength (C) The ratio of the peel strength of the layer adhesive is 1.5 times or more, the color difference aea of the base (A) and the adhesive layer (b), and the color difference Δ£ of the base (C) and the adhesive layer (B): M297647 Although the above method can be used to make artificial joints, the layers are fixed by the splicing agent, and the second:: unstable::: the protective layer "so" not only makes the upper layer of the upper material more Heart, also valley easy to make the upper surface become dirty and yellow. [New content]

The main purpose of this creation is to have the effect of resistance to yellowing. The film is bonded to the leather layer for the above purpose, and the present invention is a shoe with a yellowing resistance and a low density enamel film. The shoe includes at least one sole and one upper, and the material of the upper is Formed by a film layer and a leather layer in a high-frequency manner, wherein the material of the leather layer is an artificial leather or fabric layer; the film layer is composed of different proportions of styrene-ethylene/butylene-styrene block Copolymer (Styrene_Ethyiene/Buty丨ene Styrene

Block C〇po丨ymer, SEBS), polyolefin elastomer (p〇iy〇iefin Elastomer, POE) and ethylene/vinyl acetate copolymer fthylene_Vinyi Acetate, eva) mixed with a slip agent into a fluid-like substance, which is extruded and granulated. The granule material is formed and extruded by a τ-type die to form an nascent embryo, which is then pressed by a roller. [Embodiment] Please refer to the "1A and 1B" diagrams for the schematic diagram of the creation of the shoe and the enlarged cross-section of the partial upper of the creation. 6 M297647 As shown in the figure: This creation hurts j #You are a shoe with yellowing resistant and low-density film. 'The shoe 1 of this creation includes at least the sole 11 and the upper 19 provided on the sole 11 乂2 It can be seen from the partial enlargement area 2 that the upper is composed of a leather layer 121 and a film layer (2). Top 5? The material of the leather layer 12 is an artificial leather or fabric layer. For example, the above structure constitutes a brand new shoe with a yellow and low density film. • Refer to Figure 2 for a schematic representation of the film layer. As shown in the figure: the film layer 122 is composed of 5 to 5 % of styrene-Ethylene/Butylene-Styrene Block Copolymer (SEBS) 1221, 30~ 80% polyolefin elastomer (p〇ly〇lefin

Eiast (10) er, POE) 1222, 5 to 15% Ethylene-Vinyl Acetate (EVA) 1223 and slip 1224 are made, and the slip agent 1224 can be a sarcophagus or an amine system, and The thickness of the film is less than 1 and the thickness is between 〇17~2 〇. ★ 凊 Refer to “3rd to 6th” for the steps of step a of creating a film layer for this creation, the step b of creating a film layer for this creation, the diagram of step c of creating a film layer and the creation of the creation. A schematic view of the step d of making a film layer. As shown in the figure: when the film layer 122 of the present invention is produced, the following steps are included: Step a: Take 45% "KRATON" company code G1651 material styrene-ethylene/butylene-styrene block copolymer 1221. , 4〇0/〇7 M297647

Mitsui Elastomers Singapore" company number DFl 10 polyolefin elastomer 1222, 15% "USI" company number UE629 ethylene / vinyl acetate copolymer 1223 and with the lubricant 1224 as a twin screw 31 mixing machine 3 in Celsius 180 The materials were uniformly mixed into a fluid-like substance 122a at a shear force of a twin-screw 31 at ~250 degrees. Alternatively, the film layer 122 can be added to the kneader 3 to add the desired pigment so that the film layer 122 has the desired color. Step b: The mixed fluid-like substance 丨22a is extruded and granulated at an extruder 4 having a double screw 41 at a temperature of 18 degrees Celsius to form a particulate material 122b. Step c: The granule material is extruded with a τ-type die a (t_Die) to form an primordial 122c.

y step d: The initial layer 122c is formed by rolling the b to form a film layer 122. The density of the film layer 122 after molding is less than 1, and the thickness is between 0.17 and 2.0 mm. In addition, after the film layer 122 was completed, the actual test was carried out. The film 22 was irradiated with a UV bulb of 300 W for 2 hours, and the ring of Na Na was continuously irradiated for 24 hours. After that, the film layer 122 was taken out and the JIT 2 standard color card was taken out. For comparison, the number of yellowing turns is 4 to 5, so it can be proved that the film layer 122 has the effect of resisting yellowing. 8 M297647 Please refer to "Fig. 7", which is another society of the present creation. As shown in the figure, the upper layer of the upper layer (2) is covered with leather according to Fig. 3, and: 6 weeks high = :: the film layer 122 is bonded to the leather layer 121 to form the upper 12j. Figure 8 is the other part of the creation - the upper name of the shoe: intention. As shown in the figure: the upper 12a can be sandwiched between the leather layer ^ and the film layer 122.
