[0029] Embodiment
[0030] Such as Figures 1 to 6As shown in the figure, a soft leather includes a base cloth layer 1, a genuine leather layer 2, and a wear-resistant layer 4. The base cloth layer 1 is a non-woven fabric layer. The genuine leather layer 2 is disposed on the upper surface of the base cloth layer 1. A soft layer 3 with continuous serrations is provided between the genuine leather layer 2 and the wear-resistant layer 4. The upper surface of the soft layer 3 is firmly connected to the wear-resistant layer 4, and the lower surface of the soft layer 3 is fixedly connected to the genuine leather layer 2. An arc groove 41 extending along the width direction of the wear-resistant layer 4 is formed on the wear-resistant layer 4 by hot pressing with a hot press. First ventilation holes 21 and second ventilation holes 11 are respectively formed on the genuine leather layer 2 and the base cloth layer 1 by a punching machine. An air-permeable groove 12 communicating with the second ventilation holes 11 is formed on the upper surface of the base cloth layer 1 by hot pressing with a hot press. The air-permeable groove 12 and the first ventilation holes 21 are staggered. With this structure, through the mutual cooperation of the arc groove 41, the soft layer 3, and the air-permeable groove 12, the softness of the leather can be greatly improved, thereby improving the wearing comfort.
[0031] As Figure 1 and Figure 2 shown in the figure, the soft layer 3 includes a convex portion and a concave portion, which are formed by hot pressing with a hot press. An air-permeable channel 31 is formed between the convex portion and the concave portion. Ventilation openings 32 are formed on both side walls of the convex portion by a punching machine; the first ventilation holes 21 are located directly below the convex portion; the arc groove 41 is located directly above the concave portion; longitudinal holes 42 communicating with the arc groove 41 are formed on the wear-resistant layer 4 by a punching machine; the ventilation openings 32 and the longitudinal holes 42 are formed by... With this structure, by providing the longitudinal holes 42, the first ventilation holes 21, the second ventilation holes 11, the air-permeable channel 31, and the ventilation openings 32, the air inside and outside the leather can circulate and exchange through the longitudinal holes 42, the ventilation openings 32, the first ventilation holes 21, and the second ventilation holes 11, thereby effectively ensuring the air permeability of the leather and improving the comfort of the driver; furthermore, the staggered distribution of the longitudinal holes 42, the ventilation openings 32, the first ventilation holes 21, and the second ventilation holes 11 also makes the leather waterproof to a certain extent.
[0032] As Figure 2 shown in the figure, both the first ventilation holes 21 and the second ventilation holes 11 are trumpet-shaped ventilation holes. The diameter of the first ventilation holes 21 gradually increases from top to bottom, and the diameter of the second ventilation holes 11 gradually decreases from top to bottom. In this structure, the first ventilation holes 21 with a diameter gradually increasing from top to bottom can increase the gas accommodation capacity inside the first ventilation holes 21, and the second ventilation holes 11 with a diameter gradually decreasing from top to bottom can increase the gas accommodation capacity inside the second ventilation holes 11, so that the air entering the air-permeable groove 12 can be better discharged from the air-permeable groove 12, thereby accelerating the air flow inside the leather and enabling the leather to conduct multi-directional ventilation and greatly improving the air permeability.
[0033] As Figure 6As shown, the wear-resistant layer 4 is woven by warp and weft yarns 4c, wherein the weft yarns 4c and the warp yarns are put into a water jet loom and woven to form the wear-resistant layer 4, the warp yarns include a first warp yarn 4a and a second warp yarn 4b that are staggered, the first warp yarn 4a is twisted by Lycra fiber, the second warp yarn 4b is twisted by Lyocell fiber, the weft yarn 4c includes a core yarn and a covering yarn that are processed by a spindle spinning process to form the weft yarn 4c, the core yarn is twisted by flax flame-retardant fiber through a twisting machine, and the covering yarn is twisted by Cordura fiber. With this structure, the first warp yarn 4a is twisted from Lycra fiber by a twisting machine, and the covering yarn is twisted from Cordura fiber by a twisting machine. The Lycra fiber and Cordura fiber have excellent wear resistance, so that the wear resistance of the leather surface can be improved; the second warp yarn 4b is twisted from Lyocell fiber by a twisting machine, and Lyocell fiber has the smooth touch and softness of silk, so that the leather has a better feel; the flax flame-retardant fiber has moisture absorption and heat dissipation, health care and antibacterial, anti-fouling and antistatic properties, UV protection, and excellent flame retardant effect, so that the produced leather has excellent flame retardancy.
[0034] like Figure 5 As shown, the soft layer 3 is woven by the warp and weft of soybean protein fiber yarn 3a and spandex yarn 3b, wherein the soybean protein fiber yarn 3a and spandex yarn 3b are put into a water jet loom and woven to form the soft layer 3. With this structure, the soybean protein fiber has moisture conduction and breathability, good skin affinity and antibacterial properties, and has a cashmere-like feel and silky luster, so that the leather has a good feel and breathability; the spandex fiber has high elasticity, so that the soft layer 3 has the characteristics of soft and smooth feel, good elasticity, etc.
[0035] In this embodiment, the base fabric layer 1, the leather layer 2, the soft layer 3 and the wear-resistant layer 4 are bonded together by hot melt adhesive. With this structure, since the base fabric layer 1, the leather layer 2, the soft layer 3 and the wear-resistant layer 4 are bonded together by hot melt adhesive, the connection is firm, so that the layers are not easily separated, thereby effectively ensuring the stability of the overall structure of the leather.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
