Towel materials mainly include cotton, viscose (including bamboo fiber, wood fiber, modal, etc.), silk and functional ultra-fine polyester fiber. In the past two years, kapok yarn was also popular for making towels. The reason was that a professor from Donghua University patented kapok spinning, claiming that kapok fiber has better water absorption and warmth retention than cotton fiber. In fact, the professor was just imagining it. He only noticed that the middle cavity of kapok fiber was larger, but did not notice that the cavity wall of kapok fiber was extremely thin and brittle.
Cotton fiber and viscose fiber are widely used in towels due to their good water absorption and relatively good skin-friendly properties; silk itself has excellent skin-friendly properties because it is a protein component. The towels woven from it are the best beauty towels, but because of the high cost, domestic consumers rarely see them. As for microfiber towels, which are known as absorbent towels, they are more commonly used as rags.
By the way, to correct what the previous netizen said, kapok has nothing to do with beech. Kapok is the fiber in the fruit of the kapok tree. Because it is very similar to cotton, it is called kapok.
