Problems solved by technology

The melting temperature of polyester fiber is about 270°C. At this temperature, ordinary phase change materials and their capsules will carbonize, melt, shrink, etc., causing the capsule wall to rupture, causing the internal phase change materials to leak out and burn. , so there is no polyester-based fiber product in the smart temperature-regulating fiber

Abstract

The invention relates to the field of intelligent temperature-adjusting fiber, in particular to terylene-based intelligent temperature-adjusting fiber and a manufacturing method thereof. The terylene-based intelligent temperature-adjusting fiber comprises polyester fiber, a PCM (phase-change material) capsule body, and a PCM capsule wall. The terylene-based intelligent temperature-adjusting fiber is characterized in that the mass percentage of the PCM capsule body and the mass percentage of the PCM capsule wall are 55-60% and 40-45% respectively; the PCM capsule body internally comprises the following materials in percentage by mass: 70% of low-melting-point paraffin, 20% of high-purity activated carbon powder and 10% of a dispersing agent, wherein the melting point of the paraffin is 25-35 DEG C, the purity of the high-purity activated carbon powder is higher than 95%, and the dispersing agent is an emulsification dispersing agent; the capsule wall is made of a polysulfone amide material, and the heat shrinkage rate of the polysulfone amide material is smaller than or equal to 1%. Compared with the prior art, the polysulfone amide material is used in the capsule wall of the intelligent temperature-adjusting fiber capsule body, so that the heat shrinkage rate of the intelligent temperature-adjusting fiber capsule body is smaller than 1% in 30 min, and an obtained terylene-based intelligent fiber material has excellent spinnability and enthalpy value.

Description

technical field [0001] The invention relates to the field of intelligent temperature-regulating fibers, in particular to a polyester-based intelligent temperature-regulating fiber and a manufacturing method thereof. Background technique [0002] Intelligent temperature-regulating fiber is a high-tech product developed by combining phase change thermal storage material technology with fiber manufacturing technology. When the temperature of the external environment rises, the textiles containing phase change materials absorb heat and change from solid to liquid, reducing the body surface temperature. On the contrary, when the temperature of the external environment is lowered, the phase change material releases heat and changes from liquid to solid, which reduces the heat emitted by the human body to the surroundings, so as to maintain the normal body temperature of the human body and provide a comfortable "inner clothing microclimate" environment for the human body. The huma...
