The treated full grain leather is soft, breathable and waterproof, and is suitable for manufacturing upper leather of leather shoes of single leather shoes, leather sandals, cotton leather shoes, fur leather shoes, training shoes, combat and training boots and the like.
Description
Technical Field
The invention belongs to the technical field of C14C9/02, and particularly relates to application of breathable soft leather to shoemaking.
Background
Before being applied to shoe preparation, the animal leather needs to be processed to remove hair on the surface of the animal leather and remove redundant grease of the leather, and protein in the leather is denatured through the treatment of physical means and chemical reagents, so that the effects of wear resistance, difficult putrefaction and softness of the leather are achieved. However, because the leather fabrics are modified by leather, the leather fabrics easily swell when being in water, and the quality of leather and shoes is reduced, so most enterprises can perform waterproof treatment in the leather processing process in order to solve the problem of quality reduction of leather when being in water. However, the waterproof effect and the air permeability effect of leather are affected, and after the leather is made into shoes, the problems of foot stuffiness, sweat stuffiness, foot odor and the like can be caused, and particularly for special shoes such as training shoes, combat training boots and the like, the leather needs to have the waterproof and air permeability effects and to be soft and not to hit feet.
Chinese patent CN101993962B discloses a soft leather, which is obtained by adding fluorine-containing substance as water-proofing agent and thermoplastic resin as finishing agent on the surface of leather during the leather treatment process, but the leather has poor air permeability.
Based on the application, the invention provides application of the breathable soft leather to shoe making.
Disclosure of Invention
In a first aspect of the present invention, there is provided a breathable soft leather, wherein the leather is at least one selected from the group consisting of natural leather, synthetic leather, regenerated leather, and artificial leather.
In a preferred embodiment, the natural leather is selected from at least one of pig leather, cow leather, sheep leather, horse leather, donkey leather, and camel leather.
In a preferred embodiment, the bovine leather is selected from at least one of yellow cattle leather, buffalo leather, yak leather.
In a preferred embodiment, the buffy leather is selected from the group consisting of top leather and split leather.
In a preferred embodiment, the buffalo leather is top leather.
In a preferred embodiment, the top layer leather is selected from at least one of full grain leather, suede leather, soft top leather, and shredded leather.
In a preferred embodiment, the top leather is finished.
The full grain leather has complete surface layer, can clearly show the leather with special texture on the surface of the animal skin, is soft and elastic, has good air permeability, and is suitable for being used as shoe upper leather. The full grain leather without finishing treatment has poor texture and granular official feelings and unclear textures and granular surfaces. Compared with full grain leather, the leather of the finished leather is hard, and the product is not easy to deform. Compared with full grain leather, the soft top leather is brighter, softer and more delicate in hand feeling, and is suitable for serving as shoe lining leather and inner pad leather.
In a preferred embodiment, the raw material for the coating treatment is at least one selected from the group consisting of polyacrylic acid derivatives, silicone resins, polyurethane resins, sulfate ester derivatives, hydrocarbons, and synthetic fats and oils.
In a preferred embodiment, the raw materials for the finishing treatment include polyacrylic acid derivatives and silicone resins.
In a preferred embodiment, the polyacrylic acid derivative is available from Fulvin chemical, inc. under the model Jinton PA-11.
In a preferred embodiment, the silicone resin is purchased from fugine chemical (suzhou) limited under the model number jintanquor sid.
In a preferred embodiment, the mass ratio of the polyacrylic acid derivative to the silicone resin is (2-5): (10-13).
In a preferred embodiment, the raw materials for the coating treatment further comprise deionized water and a volume-promoting dispersant.
In a preferred embodiment, the pro-volume dispersant is ethyl hexanediol.
In the experimental process, the applicant finds that the polyacrylic acid derivative and the organic silicon resin are used as active substances in the upper leather treatment agent, and particularly the mass ratio of the polyacrylic acid derivative to the organic silicon resin is limited to (2-5): (10-13), the applicant found that the prepared upper leather has good waterproof, light-resistant and breathable effects. The applicant speculates that the possible reasons are that the existence of the polyacrylic acid derivative promotes the combination of the organic silicon resin and the leather surface, the absorption capacity of the leather surface to the organic silicon resin is improved, the organic silicon resin is uniformly distributed on the leather surface, and the waterproof capacity of the leather is improved on the premise of not changing the air permeability and the soft characteristic of the leather by adding the organic silicon resin. However, the applicant finds that if the content of the organic silicon resin is increased in the application, the increased organic silicon resin forms a film layer with a dense molecular structure on the leather surface, a sealing effect is formed on the leather surface, and the air permeability of the leather is reduced.
In a second aspect, the invention proposes the use of a breathable soft leather, said leather being used in the field of footwear.
In a preferred embodiment, the method is applied to manufacturing upper leather, lining leather and inner pad leather.
In a preferred embodiment, the upper leather is full grain leather, and the shoe lining leather and the inner pad leather are soft upper leather.
In a preferred embodiment, the method is applied to the manufacture of leather shoes, including leather shoes, sandals, cotton leather shoes, training shoes and combat and training boots.
In a preferred embodiment, the leather of the leather shoes can decompose harmful aromatic amine dye, the content of formaldehyde and the content of heavy metal meet the national standard.
Compared with the prior art, the invention has the following beneficial effects:
the invention adopts full grain leather as upper leather for shoemaking, which improves the air permeability and flexibility of the prepared shoes, meanwhile, the full grain leather adopted by the invention is tanned and coated and then treated by a coating agent containing organic silicon resin, polyacrylic acid derivative and the like, the polyacrylic acid derivative promotes the combination of the organic silicon resin and the leather surface, the absorption capacity of the leather surface to the organic silicon resin is improved, the organic silicon resin is uniformly distributed on the leather surface, the addition of the organic silicon resin improves the waterproof capacity of the leather on the premise of not changing the air permeability and the soft characteristic of the leather, and the leather is endowed with certain light resistance and heat resistance. The upper leather provided by the invention can be used for manufacturing various types of leather shoes, such as single leather shoes, leather sandals, cotton leather shoes, training shoes and combat training boots, and ensures the wearing comfort, good ventilation and waterproof effects of various types of leather shoes.
