Problems solved by technology

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

Abstract

The invention relates to the field of phase-change materials for fibers, and particularly speaking, relates to a phase-change-material master batch capable of being used for a dacron-based air conditioning fiber and a manufacturing method thereof. The phase-change-material master batch comprises a phase-change-material capsule particle and a phase-change-material capsule capsule-wall. The phase-change-material master batch is characterized in that the percentage (by mass) of the phase-change-material capsule capsule-wall and the phase-change-material capsule particle are 55 to 60 percent and 40 to 45 percent respectively; the phase-change-material capsule particle is prepared from the following materials in percentage by mass: 70 percent of low-melting-point paraffin, 20 percent of high-purity activated carbon powder and 10 percent of dispersing agent, wherein the melting point of the paraffin is 25 to 35 DEG C, the purity of the high-purity activated carbon powder is 95 percent or above, and the dispersing agent is emulsion dispersing agent; the capsule-wall is made from a polysulfone amide material; the thermal shrinkage rate of the polysulfone amide material is not more than 1 percent. According to the phase-change-material master batch capable of being used for the dacron-based air conditioning fiber, in comparison with the prior art, the polysulfone amide material is used in a capsule-wall of a capsule body of an intelligent temperature-regulation fiber; the thermal shrinkage rate of the intelligent temperature-regulation fiber within 30min is less than 1 percent; an obtained dacron-based intelligent fiber material has excellent spinnability and enthalpy value.

Description

Technical field [0001] The invention relates to the field of fiber phase change materials, in particular to a phase change material masterbatch that can be used for polyester-based air conditioning fibers and a manufacturing method thereof. Background technique [0002] Air conditioning fiber is a kind of intelligent temperature-regulating fiber, which is a high-tech product developed by combining phase change heat storage material technology with fiber manufacturing technology. When the temperature of the external environment rises in textiles containing phase change materials, the 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 decreases, the phase change material emits heat, changing from a liquid state to a solid state, which reduces the amount of heat the human body emits to the surroundings, so as to maintain a normal body temperature of the human bod...
