Good quality theater chairs are mostly made of leather materials. Because they are often used or are not easy to clean, the maintenance problem is very troublesome. Here are some simple methods.
Theater chairs and car seats are generally made of leather surfaces. In particular, the car seat is a special leather, which must be treated with anti-ultraviolet, heat-resistant, light-resistant, wear-resistant, etc., and the cost is high. Therefore, some unscrupulous manufacturers will charge the other low-cost leather, and the car mainly pays attention to distinguishing the true and false of the leather. Good or bad.
Documentary Law: The leather of the factory has clear sources, and the basic materials such as the production site, leather factory standard, leather test table and leather use authorization are all indispensable.
The labeling method: the factory leather, the back will be marked with the date of manufacture, the name of the skin factory and so on. (The date of manufacture should not be too long. If the leather is more than 3 years, it should be noted that there is no mold.)
View: Under the 30 times magnifying glass, it can be seen that the leather looks like the surface of the moon, and the hole is pitted, which is good in gas permeability. The leather is cut across the blade, and the color of the leather from the outer layer to the inner layer must be the same. Pay attention to whether there is any color difference under the outer layer to avoid buying used or dyed second-hand leather.
Olfactory method: good leather, there should be no pungent taste after treatment, so too much solvent smell and paint taste is not good.
Heat-resistance method: It is best to have a small piece of leather material with the manufacturer, and use the cigarette head to touch the hot sample for 2~3 seconds, which can avoid buying PU products. The burning time is large due to the burning of the lighter, so the time needs to be lengthened.
Wiping method: Wipe the surface of the leather with stain-free oil, pay attention to whether there is fading or falling off, and avoid buying 2 times of color-changing leather.
