Modal is a kind of regenerated cellulose fiber developed by Austrian Lanjing Company. The raw material of this fiber is beech from Europe, which is first made into wood pulp and then processed into fiber through special spinning process. The raw materials of this product are all natural materials, which are harmless to human body and can be naturally decomposed without causing environmental pollution. Underwear made of modal has a smooth and bright surface, and feels particularly comfortable. When it touches the skin, it feels cool and refreshing, and its elasticity and toughness are better than pure cotton. It is also moisture-absorbing and breathable, which is beneficial to human circulation and health. At the same time, it is durable and the more you wash it, the softer and brighter it is. It is the first choice for underwear. In this way, we have a clear idea of how modal underwear works. After knowing the benefits of modal underwear, we have a strong interest in this underwear. In real life, we can use the following methods to distinguish whether an underwear is made of genuine modal material. First, look at the tag. Where Modal fiber produced by Lanjing Company is used, every garment has a tag issued by Lanjing Company, which is usually expressed in many languages and marked with Modal registered trademark. Second, look at the price. Underwear made of modal fiber is generally expensive, ranging from tens of yuan to hundreds of yuan. If the underwear you see is extremely cheap, it must be counterfeit. Third, look at the texture. Underwear made of modal fiber is soft, breathable, close-fitting, elastic, durable, smooth to the touch and colorful.
