PVC leather for automobiles needs to meet specific technical requirements and construction processes.
First, when PVC leather is used for automobile interior decoration, it needs to have good bonding strength and moisture resistance to ensure good adhesion with various types of floors and resist the influence of humid environments. In addition, the construction process includes preparations such as cleaning and roughening the floor, and removing surface oil stains to ensure good bonding between PVC leather and the floor. During the composite process, it is necessary to pay attention to excluding air and applying a certain amount of pressure to ensure the firmness and beauty of the bond.
For the technical requirements of automobile seat leather, the Q/JLY J711-2015 standard formulated by Zhejiang Geely Automobile Research Institute Co., Ltd. stipulates the technical requirements and experimental methods for genuine leather, imitation leather, etc., including specific indicators in multiple aspects such as fixed load elongation performance, permanent elongation performance, imitation leather stitching strength, genuine leather dimensional change rate, mildew resistance, and light-colored leather surface anti-fouling. These standards are intended to ensure the performance and quality of seat leather and improve the safety and comfort of automobile interiors.
In addition, the production process of PVC leather is also one of the key factors. The production process of PVC artificial leather includes two methods: coating and calendering. Each method has its own specific process flow to ensure the quality and performance of the leather. The coating method involves preparing the mask layer, foaming layer and adhesive layer, while the calendering method is to heat-combine with the polyvinyl chloride calendering film after the base fabric is pasted. These process flows are essential to ensure the performance and durability of PVC leather. In summary, when PVC leather is used in automobiles, it needs to meet specific technical requirements, construction process standards, and quality control during the production process to ensure that its application in automobile interior decoration can meet the expected safety and aesthetic standards. PVC leather is a synthetic material made of polyvinyl chloride (PVC) that simulates the texture and appearance of natural leather. PVC leather has many advantages, including easy processing, low cost, rich colors, soft texture, strong wear resistance, easy cleaning, and environmental protection (no heavy metals, non-toxic and harmless) Although PVC leather may not be as good as natural leather in some aspects, its unique advantages make it an economical and practical alternative material, widely used in home decoration, automobile interior, luggage, shoes and other fields. The environmental friendliness of PVC leather also meets national environmental protection standards, so when choosing to use PVC leather products, consumers can rest assured of its safety.
