Problems solved by technology

However, in the impregnation method, the phase change material is easy to lose, and the filling amount of the phase change material in the fiber is low. In the composite spinning method, the phase change material is easy to lose, and the spinning performance is restricted. However, the microcapsule method can stabilize the phase change material. Exist in fibers, but with low addition of phase change material and high manufacturing cost

Abstract

The invention discloses a phase-variable energy-storage fiber and relative production, which comprises that using cellulose slurry to prepare cellulose adhesive solution, to be mixed with phase-variable wax fused solution to prepare spinning dope to obtain the phase-variable energy-saving adhesive fiber. The functional fiber is mainly formed by cellulose and wax, while the wax content is 10-40% (relative to the cellulose content). And the inventive production has simple process, significantly reduced phase-variable material loss in the process, improve the phase-variable material content and improve the phase-variable energy-saving function and mechanical function.

Description

technical field [0001] The invention relates to a composite fiber, in particular to a phase change energy storage fiber with temperature change buffering function and a preparation method of the fiber. Background technique [0002] Substances in nature exist in three states: solid, liquid, and gas, and substances can be transformed between solid, liquid, and gas under certain conditions and temperatures. The transformation process is called phase transition. Heat and release heat, this property of matter has been widely used by people. Among them, the phase change energy storage fiber is the application of people to this characteristic of matter. [0003] The most important function of clothing is to maintain the normal temperature of the human body and make the human body feel comfortable. The heat transfer of clothing can basically be divided into sensible heat transfer, that is, the heat transfer caused by the difference between the human body temperature and the extern...
