maintenance and cleaning methods: 1. Stain spots Use a clean sponge dipped in a mild soap solution to wipe the dirt, then wipe it off with water, and then let the leather dry naturally. If the stain is very stubborn, you may need to use a detergent solution to deal with it, but you must wipe it carefully to avoid damaging the leather surface. 2. High temperature and sunlight Try not to let the leather products come into contact with the sunlight or close to any heater, otherwise the leather will become more and more dry, and the elasticity and softness of the leather will gradually disappear. 3. Juice Use a clean cloth or sponge to dry the juice immediately. If necessary, use a cloth dipped in clean warm water to wipe off the juice, and then let the leather dry naturally. 4. Butter or grease Use a clean cloth to wipe off the grease on the surface, and let the remaining grease stains slowly penetrate into the leather. Never use water to wipe the grease stains. Common materials and properties of computer bags
: Generally, the raw materials of the fabrics used on computer bags are nylon (nylon) and polyester (polyester). Occasionally, there are two kinds of materials mixed together, nylon and polyester (also called polyethylene). ) Both materials are extracted from petroleum. Nylon is of better quality than polyester, and of course it is a bit more expensive. In terms of performance. Nylon is softer. Polyester, also commonly known as 'XinliangPolyester yarn formed by texturing and other processes. The most prominent feature is its good shape retention. Wearing polyester clothes are crisp and not wrinkled. Looks very energetic and fit. After he washes it, he doesn't need to iron it, and it is smooth as usual. Polyester has a wide range of uses. Polyester is usually combined with wool and cotton. Silk is blended, and all kinds of polyester cotton, polyester wool, polyester silk and polyester viscose clothing and garments on the market are the products. Polyester fabric performance 1. Good wrinkle resistance and heat preservation. 2. High strength, easy to wash quickly. 3. Good heat resistance. 4. Good stability against sunlight. 5. Strong wear resistance. 6. The chemical performance is relatively stable. 7. Antibacterial and microbial effects. Nylon, also called nylon, is made by the polymerization of hydantoin. His abrasion resistance can be called champion among all heavenly fibers and chemical fibers. In many textiles, nylon is mixed. Improve abrasion resistance. Nylon is the earliest synthetic fiber variety in the world. Nylon fabric performance 1. Good abrasion resistance. 2. High intensity. 3. High elastic restoring force and good fatigue resistance. 4. Good moisture absorption performance. 5. It has the characteristics of light specific gravity. 6. Good alkali resistance.
