Abstract

The invention discloses a functional yarn and application thereof, and the preparation method of the functional yarn comprises the steps of laminating a first material layer and a second material layer in the thickness direction to obtain a composite material layer, winding the composite material layer to obtain a cylindrical composite material roll, filling the composite material roll with the composite material layer from inside to outside along the radial direction of the composite material roll, and stretching the composite material roll in the axial direction of the composite material roll to obtain the functional yarn, wherein the diameter of the composite material roll is 1.68-2 cm, and the composite material roll is wound in the width direction of the first material layer or the second material layer and is curled from one side to the other side. The functional yarn is obtained by winding and stretching the composite material layer, and the fabric woven by using the functional yarn has good cool feeling and ultraviolet resistance, does not need to be compounded with other functional fibers, does not need to be subjected to post-treatment or film coating, and has good ultraviolet resistance while having good cool feeling.
