Towels for hotel use have to be of a better quality as compared to towels for family use. These towels should be thicker, softer and more absorbent, in addition to being able to endure heavy washes under high temperatures. Whiteness is another important criteria of hotels. Most hotels prefer their towels to be bleached white and this whiteness must be maintained after several washes. As you know, towel is made up of a constrcuction of three layers yarn-bottom layer(warp layer), middle weft layer and top floating thread. The key to prevent the yellowish of the towel is to bleach the yarn for the bottom layer before weaving the towel separatedly and the other two layers should be kept as gray yarn to bleach with bottom layer after weaving. It also reserves softness and absorption of towels。
