Generally speaking, cashmere products can be divided into two categories: pure cashmere products and cashmere products: the cashmere content standard for pure cashmere products is more than 95%, and the cashmere product content standard is more than 30%. Those with cashmere content below 30% cannot be called cashmere products. Therefore, when purchasing a cashmere sweater, you must carefully identify it. The usual method is to take a look, weigh it twice, and pinch it three times. At first glance, look at the brand first. You must first choose a brand that emphasizes credibility, quality, and reputation. This can save you a lot of trouble and worries. Never randomly choose cashmere products that do not have a factory address, trademark, or cashmere content indicated. Then look at the quality of the product. A high-quality cashmere sweater has a soft luster, plump suede, and strong wool texture. Its surface is milled with a layer of fine velvet, and the density of horizontal and vertical coils is even. This is more obvious if looked at under bright light. Weigh twice, that is, weigh once with your hands when purchasing. Because cashmere is a very soft fabric, lighter than wool, pick up the product and weigh it when purchasing. This is an easy way to distinguish cashmere products from wool products. Three pinches, that is, one pinch with your hands. Cashmere sweaters have a strong fluffy feel and are extremely flexible. Therefore, when purchasing, you can pinch them with your hands and observe their recovery. This is not only a way to identify its authenticity, but also a way to distinguish its quality.
