There are snow boots made of chemical fiber, artificial wool, wool and other materials on the market. Among them, the selection of wool snow boots is the most pure. There are many inferior products or counterfeit products flooding the market, so when choosing wool snow boots, four tips teach you to choose pure wool snow boots, which can be distinguished by looking, touching, smelling and burning:
（1） Look
Carefully observe the wool color. The high-quality wool snow boots are processed with foreign high-quality environmental protection dyes and additives and advanced technology. The wool color is bright, vivid and soft; Inferior goods are dim in color, easy to fade and cross color; If the snow boots are spliced from different colors, pay attention to whether there is color difference in the same color; The evenness and density of the suede of the cut snow boots should be paid special attention to
（2） Touch
1. Gently touch the wool surface with your hand. High quality wool snow boots are strictly selected with good density. When gently wiped with your hand, it feels fine and velvety; The poor hand feel is rough and sticky. This is because the high-quality wool snow boots are made of high-quality Australian lamb skin, which has a short growth period, well preserved wool scales, fine fur fibers, uniform density and elasticity.
2. Separate the fur by hand to check whether there are fur cracks, whether the leather pieces are spliced firmly, whether there are obvious seams, etc.
3. Gently pull the fur by hand to see if there is hair loss. The leather board of high-quality wool snow boots has great strength, especially Australian wool. Its breaking load is twice that of rabbit skin, so it is not easy to shed hair, and it will not let broken hair stick to clothes.
（3） Smell:
Take the product close and smell it. The high-quality wool is processed with imported tanning agent and advanced technology, and sterilized before leaving the factory, which can prevent the breeding of mites and bacteria without any peculiar smell; Poor quality wool will give off an unpleasant smell due to the unclean removal of oil.
After using wool snow boots for a period of time, just use a special comb to gently comb the fur, which can be restored to its original state. If there is a slight stain, gently wipe it with a clean towel dipped in volatile dry cleaner and dry it. If the stain is too big, you must send it to a professional shop for cleaning.
When not in use in hot weather, wool snow boots must be stored in a ventilated and dry place, and cannot be folded and pressed for a long time. If you use insect and moth proofing agents, do not directly contact the fur. In addition, before collection, it must be dried in a ventilated place, not exposed to the sun.
（4） Burn
1. For wool products, gently pull out a trace of fine wool along the edge of wool snow boots, remove a little thread, and ignite it with fire. Pure wool will curl and smoke first, with a yellow flame, with the smell of burning hair, leaving dark brown gray blocks, which can be pressed into fine powder with your fingers; After burning, fake wool forms hard lumps and cinders, which are not easy to twist and break, and there is no smell of burning hair. When burning, it will smoke and bubble while burning, accompanied by the smell of burning hair. There are many ashes, and shiny black will be brittle and massive.
2. Acrylic fiber products, when burning, melt and burn slowly at the same time. The flame is white, bright and powerful, slightly black smoke, fishy smell, gray is white, round, brittle and fragile.
3. Nylon products, while melting, burn slowly. When burning, there is a little white smoke. The flame is small, blue, with celery flavor. It is bound into light brown hard blocks, which are not easy to twist.
