The terry is formed by wrapping untwisted yarn of superfine fibers outside natural fibers, after the untwisted yarn is washed with water and dyed and shaped, the superfine fibers slide down at the top of the terry to form a low terry due to different shrinkage rates of the superfine fibers and the natural fibers such as cotton, bamboo fibers or silk which directly contact skin. The superfine fiber forming the low-looped pile can exert excellent water absorption performance, and the water absorption of the whole fabric is increased. In addition, because the twist of the cotton at the middle lower part of the terry and the superfine fiber is still in place, the hair falling rate of untwisted yarn is effectively reduced. Therefore, the soft and fluffy characteristics of the untwisted yarn fabric are preserved, the water absorption and skin affinity of the fabric are effectively improved, and the hair loss rate is reduced; and the double-layer looped pile increases the looped pile fullness of the towel fabric.

The untwisted yarn looped pile fabric produced by the invention does not use water-soluble yarn, so that the environment is not polluted, the production process is simple, and the waste is not caused.
