Phase change materials, yarns, fabrics and wearables based on microporous membranes for fabrics

Abstract

The invention relates to a phase-change material for fabric based on microporous membrane, yarn, fabric and wearings. The microporous membrane phase-change material is a microporous microcapsule thatcomprises a shell material with the microporous polymer ionic liquid polymer membrane and a core material with the phase-change material; the microporous microcapsule phase-change material is not easily soluble in water, is environmentally friendly, and has good heat absorption and heat release properties, good resistance to acid and alkali and high stability without toxic or hazardous compounds;the phase-change material is not easy to peel off or cause damage to the machine with high reuse rate and small particle size, and can be easily mixed with the spinning solution with even distributionand simple operation; the microporous microcapsule can be used for making yarn after spinning with viscose and plant powder, and the yarn can be weaved to be fabric and further processed to be wearings; the wearings manufactured are soft, smooth and comfortable without fluorescent, and can sterilize and protect skin, adjust temperature automatically under different environments, and keep body comfortable for a long time.

Description

technical field [0001] The present invention relates to microporous membrane-based phase change materials for fabrics, yarns, fabrics and wearables. Background technique [0002] Phase change material (PCM) refers to a substance that changes the state of matter and provides latent heat under the condition of constant temperature. Generally, phase change materials can be divided into solid-solid phase change materials, solid-liquid phase change materials, and solid-gas phase change materials. Since the late 1970s, NASA Space Research Institute has developed a phase change material suitable for indoor temperature ranges in order to better protect astronauts and precious equipment from the sharp changes in the temperature of the outer space. It is also applied to astronaut's clothing, shell of return capsule, etc. After entering the 21st century, through the continuous efforts of scientists, phase change materials have begun to be put into practical use. Phase change textile...

Problems solved by technology

However, the heat transfer effect of the methyl methacrylate polymer film is poor, so that the phase change heat of the core paraffin can not be well transmitted, and the heat loss is large, resulting in a waste of energy.
