The invention discloses a heat-storage light-emitting warm-keeping knitted fabric and a preparation method thereof. The heat-storage light-emitting warm-keeping knitted fabric sequentially comprises an inner layer, a functional
acrylic fiber layer and a light-emitting layer from inside to outside, the inner layer and the functional
acrylic fiber layer are interwoven together through tucking to form a double-layer structure, and the light-emitting layer is woven and fixed to the functional
acrylic fiber layer in a knitting mode; and the surface of the light-emitting layer is coated with a light-emitting
coating layer. The heat-storage light-emitting warm-keeping knitted fabric sequentially comprises the inner layer, the functional acrylic
fiber layer and the light-emitting layer from insideto outside, and the inner layer is made of cotton fibers which are good in
moisture absorption and breathability, soft and capable of keeping warm; the functional acrylic
fiber layer provides the heat-storage light-emitting warm-keeping knitted fabric with
far infrared performance, and the knitted fabric has quick heating performance under
sunlight, and can realize the functions of heat storage,warm keeping, dehumidification, quick
drying and the like; the light-emitting layer is formed by weaving light-emitting
polyester terephthalate fibers; and the surface of the light-emitting layer is coated with the light-emitting
coating layer, light irradiated by visible light is stored in the fibers, and the knitted fabric continuously emits light for a very long time in a
dark state.
