Description of the invention (1) The present invention relates to a method for making synthetic leather, and more specifically, it refers to a method for manufacturing elastic synthetic leather that is simple to manufacture and has better elasticity and moldability. According to the practice, a synthetic leather manufacturing method is used, which mainly uses a rolling method to form a film layer, and then manufactures a braided layer, which is consolidated by gluing and hot pressing. It is true that the above-mentioned synthetic leather has been widely used in various industries by the Central Standards Bureau of the Ministry of Economic Affairs and Consumer Cooperatives. However, it often faces three major problems in various applications, namely the processability, comfort and durability of synthetic leather. , Both have a considerable gap with natural leather, this situation is particularly obvious in the shoe industry; for example, the general Futong synthetic leather in the shoe lasting process, because it does not have structural elasticity, it is easier Stress residues occur at certain stress points, especially when bent at right angles or at large angles, often with convex corners and wrinkles. Therefore, when finished into finished shoes, the appearance of synthetic leather uppers after processing is not as good as Genuine leather products are beautiful. Furthermore, due to structural limitations, synthetic leather generates excessive stress during use, making the stress residues easily rupture due to tortuous movements during wearing. Therefore, it is not as durable as genuine leather. The upper made of traditional synthetic leather, because it does not have structural elasticity, so it is not as natural leather as it is to adjust its fit with the shape of the foot, so it is not Leather comfortable. Moreover, the manufacturing process of the synthetic leather made by the above-mentioned manufacturing method is not able to complete the trouble of the manufacturing process by a consistent operation. In view of this, the inventor of this case has pondered carefully and accumulated many years of professional research and development experience, and finally has the invention of this invention. That is, the main purpose of the present invention is to provide a system of elastic synthetic leather. 83. 3. 10,000 (谙 Please read the precautions on the back before filling in this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm)

Weaving method, and during the weaving process of the needle sickle base material, an elastic fiber M is woven, and the elastic fiber material is an elastic fiber made of a PU split surface, which is covered with a weaving method or bare. Knitting fabric made by weaving. The covering method is that the outer part of the elastic fiber is covered with a layer of polyurethane or nylon. The polyester fiber can also be covered with a layer of natural fiber (or a mixture of natural polyester). Stranding), naked weaving method is made by elastic fiber and polyester iron (or natural polyester mixed fiber) directly on the knitting machine under uncovered conditions, and the polymer is Is to dissolve the high-molecular polymer in a solvent according to a specific ratio to form a solution, and to form the solution at least once on at least one side of the knitted substrate, and form a predetermined thickness on the surface of the knitted substrate; Has been coated with a polymer The Val substrate is impregnated in a complex solution containing a solvent and a non-solvent, and is left for a certain period of time, so that the solvent in the polymer polymer and the non-solvent of the complex solution have an internal displacement effect, resulting in a polymer coating layer. The polymer solidifies and forms an open microporous structure. Next, the solvent remaining on the surface of the solid substrate of the solidified polymer is washed with water, and finally, a drying step is performed to crack into an elastic synthetic leather.

Description of Invention (6) Method (Dipping) It is then made with a coating method. The process is as follows: when the knitted substrate 10 enters a slot 1A, and is impregnated with a polymer polymer compound solution, the knitted substrate 10 is then rolled through the rollers 2A, 2A '. Rolling, so as to control the thickness of the impregnated compound solution on the substrate, and allow the excess compound solution to flow back into the groove 1A, and then the knitted substrate 10 impregnated with the compound solution enters the first solidification 棰 3A, so that it solidifies and forms an opening Type microporous structure, and then the rollers 4A, 4A 'roll to squeeze out the excess water, and then through the heating function rollers 5A, 5A', the remaining water is ironed and ironed, so that the knitted base The moisture content in the material 10 is about 5 to 10%. Then, the knitting substrate 10 with the compounding liquid solidified on the surface is passed through a coating device 6A, and a second layer of the compounding liquid is applied thereon. The second layer of impregnated and coated resin can be the same or different Resin, then re-solidified 7A through the second coagulating bath, water washing tank 8A, 9A drying device drying, may also be formed of another elastic synthetic leather. According to the description of the two embodiments described above, it can be known that the elastic synthetic leather of the present invention can be processed by a consistent operation method, the process is complete, and because its base structure contains the effect of elasticity, it can show harmony The skin layer has a very similar structural elasticity. When it is pulled by force, it can be fully stretched. When the tensile force disappears, it can quickly return to the state before the force. This makes the product manufactured by applying the elastic synthetic leather of the present invention. , It will not be easily deformed due to the use of the user, and therefore its formability and durability are improved, and the elastic leather can be treated differently according to the needs of the user, so that it has a different appearance, such as nubuck leather , Calfskin, mirror leather, etc., can be further processed to make the surface and color match the user's needs, such as: (1) the surface of the substrate is treated with abrasive material, and the effect of grinding leather is obtained.

(3) Apply or transfer PU film or colored polymer film to synthetic leather to get the desired skin effect. (4) Embossing a predetermined pattern on the synthetic leather with a concave or convex wheel to obtain the desired skin feel. In addition, in the production of synthetic leather, the cooperation of each process is as follows: 1. The coagulation tank 7 of the first embodiment, the best tension is controlled below 1kg / cm2, and the coating layer 窿 avoids contact with the idler. Because the coating layer is not completely solidified, the structure of the coating layer encountered will be squeezed and the elasticity of the structure will be reduced. 2. After the needle-wound base material 10 covered with the polymer polymer 20 is transported to the internal solidification tank 7, the polymer polymer 20 coated thereon has also coagulated. When it enters the water washing tank 8 again, it can be used The non-solvent cleans the solvent remaining in the porous structure of the coating layer, thus completing the entire solidification process. 3. When entering the drying device 9 for drying, it can be adjusted to a predetermined temperature so that it can be completely dried without harming the product (the upper temperature limit is 150T). 4. After drying, the product is wound by a take-up roll. take.
