Abstract

The invention relates to the technical field of materials, in particular to a preparation method of temperature-adjusting fiber, the temperature-adjusting fiber and a fabric. The preparation method of the temperature-adjusting fiber comprises the following steps of preparing core-shell / phase-change material composite particles; spraying out a first component and a second component containing the core-shell / phase change material composite particles through spinneret orifices in a spinneret plate, wherein the spinneret orifices include first spinneret orifices and second spinneret orifices surrounded by the first spinneret orifices, the first component is sprayed out from the first spinneret orifices, and the second component is sprayed out from the second spinneret orifice; and enabling the first component sprayed out from the first spinneret orifices to wrap the second component sprayed out from the second spinneret orifices to form nascent fiber, enabling the nascent fiber to pass through an air layer and then enter a coagulating bath, collecting the nascent fiber through a winding drum after the nascent fiber is discharged from the coagulating bath, and then stretching the nascent fiber in hot water to obtain the temperature-adjusting fiber. A phase-change material can release heat and become warm when the temperature is low, so that the temperature adjusting effect is achieved; and the phase-change material is located in the fiber and can resist friction and washing.

Description

technical field [0001] The application relates to the field of material technology, in particular, to a method for preparing tree temperature-regulating fibers, temperature-regulating fibers and fabrics. Background technique [0002] At present, with the improvement of people's living standards, consumers have higher and higher requirements for the functionality and comfort of textiles, and the demand for comfortable textiles is increasing day by day. Regenerated cellulose fiber textiles are chemical fibers obtained by spinning natural cellulose and / or cotton linters through a series of processing procedures to prepare spinning solutions. The textile products made of them have the characteristics of softness, moisture absorption and comfort. [0003] In order to achieve a certain temperature-regulating effect in existing technical clothes, the surface of the fiber is usually impregnated with a temperature-regulating material or blended with a temperature-regulating material,...
