How should plant leather be maintained and protected?

In terms of leather tanning methods, the remaining soft tissue after removing the remaining soft tissue is continuously stretched and dried after soaking in lime water. Compared with the leather under further tanning, it will be harder and more brittle, and it will often be used in parts that should not be bent, such as drum leather. In terms of vegetable tanning, plants containing tannic acid will be used for tanning. More soft texture and brown effect. However, with the passage of time, it will continue to fade and be water-resistant. After soaking and drying, it will shrink more and become harder. The dough is also known as embryo skin or tannin tanning. After using aluminum salts such as alum, flour, gluing agent, egg yolk and other proteins are added for component tanning. It is softer than vegetable tanned leather in texture and will rot in water. Since the liquid under the influence of hot water or hot wax will better deal with hard tanned vegetable products, it will be mainly used to make books or armor for revision from a traditional point of view. Chrome tanned leather is usually invented in 1858, and more chrome salts such as chromium sulfate are used for tanning. Compared with vegetable tanned leather, chrome tanned leather will be softer, less discoloration or shrinkage, and more convenient for dyeing. In terms of brain tanned leather, emulsified fat can be used for tanning, which is more soft and water-resistant. Many tanned leather will be treated with water resistance and softness by oiling, In the process of our use, we continue to oil regularly, so as to supplement the continuous loss of oil, so as to achieve our purpose of maintaining leather.
In many non perishable and denatured animal skins that can be obtained after chemical or physical processing such as tanning or depilation, they can be transformed into leather through continuous modification and finishing. The natural protein fiber is composed of leather tightly woven in a three-dimensional space, and there will be a special grain layer on the surface of the leather, which is more comfortable in hand feeling and has more natural luster and grain pattern. Because leather has the properties that natural materials should have, and has high strength, bending resistance, tear resistance and mechanical strength, it will be easier to form and process under a certain elasticity and plasticity, and it will not be easy to change in the process of producing various leather products, which is easier to maintain and maintain the natural appearance for a longer time, It will be more excellent in stability and heat resistance, more resistant than some chemicals and better in aging resistance. Due to excellent moisture absorption, air permeability and moisture removal, it will make wearing more comfortable and hygienic.
In terms of recycled leather, there are many processes in which chemical raw materials can be mixed and processed after crushing the foot materials of animal dermis and waste subcutaneous. Because the surface processing process is similar to the embossed leather or shaving leather of dermis, the main feature is that the utilization rate is relatively high, the edges of the leather are more neat and the price is cheaper, but the existing problem is that the strength of the leather body will be worse and thicker, In terms of lever bag, briefcase and club sleeve, it can be better made into affordable belts and qualitative process products, which are more consistent and uniform under the fiber structure and longitudinal section, so as to better identify the solidification effect under the mixed fiber fluid. In terms of artificial leather, it is also commonly known as rubber and imitation leather. It is mainly a general term for PU, PVC and other artificial materials. Mainly non-woven fabric base and textile fabric base.
