Description

Multi-layer towel capable of being dyed in one bath and having excellent water absorbability Technical Field The present invention relates to a multi-layered towel excellent in water absorbency, which can be double-dyed in one bath, and more particularly, to a multi-layered towel which can be dyed into various patterns by double-dyeing a terry cloth woven by alternately arranging and weaving first pile yarns and second pile yarns in one bath. Background Recently, studies on complex high-functional fibers having various functions are actively being conducted in the fiber industry. In particular, the technological development trend of raw yarn and fabric is proceeding toward differentiation and further improvement of the functionality of clothing, and in order to improve the quality of life of human beings, development of functional materials including safe, healthy, high-quality products is proceeding. The development of such functional materials is being carried out in various fields of the fiber industry, and is no exception in the field of daily necessities. Importantly, living necessities such as towels that are in direct contact with the skin need to have a soft feel and good absorbency, and to maintain a clean feel. Further, since frequent washing is required for the purpose of use, durability against washing is required. For this reason, cotton fibers are mainly used as a material of towels. Although the cotton fiber has high hygroscopicity, the cotton fiber contains a large amount of hydroxyl groups (-OH) as hydrophilic groups in the main chain of cellulose as a main component, and thus has a problem that absorbed moisture cannot be removed rapidly and a problem that feel is deteriorated due to repeated washing. In addition, in general, a towel used for removing moisture or sweat occurring after bathing or exercising needs to be capable of rapidly removing moisture or sweat remaining on the skin without causing irritation to the skin, but there is a limitation in the case of using 100% cotton yarn. In order to solve such a problem, although there are cases where a blended yarn of synthetic fibers and natural fibers or a blended yarn of bamboo fibers and synthetic fibers is used, there are problems in that a finished product is colored due to the difference in dyeability and fastness of the synthetic fibers and natural fibers and a part is whitened due to repeated washing and rubbing.
