First, smell: knitted clothing more, in order to save costs, some manufacturers use inferior materials to produce knitted clothing, such as chemical fibers, chemical fibers are harmful to the human body and hurt the skin, especially women with soft skin, easy to buy poor quality knitted clothing allergies. Children's sweater manufacturers suggest that before buying knitwear, it is recommended to smell the clothes, if there is a strong odor, try not to buy such knitwear. Second, pull a pull:One of the more common problems with knitwear is the elasticity of the clothes. Many look very beautiful knitwear, buy back less than a few days, the clothes like a rubber band infinite extension, deformation, after that you certainly do not want to wear that clothing. This is because the elasticity of the clothes was not checked at the time of purchase. If the elasticity is not enough, the knitwear will be deformed after washing, and if you don't pay attention when drying, the knitwear will become longer and the deformation will become more serious. Therefore, remember to pull before buying, choose knitwear with good elasticity, do not just look at the design of the clothes, do not pay attention to the quality. It is still necessary to go to the store to buy the famous knitted brand. Third, ask about the cleaning:Some knitwear is very expensive and can not be washed with water only dry cleaning. For such knitwear, if you are not particularly patient and economical, try not to buy knitwear that can only be dry-cleaned. Even if you can really afford it, every time you wear it you have to take it to the dry cleaners to clean it, so be sure to ask about the cleaning when you buy it. Fourth, check the threads on the surface:If a knitted garment is badly beaten, even if only one thread is not attached, the garment will be scattered after many pulls. People who have beaten sweaters should understand this. A thread can not be connected, the whole piece of clothing is white knitting, the remedy is useless.
