Abstract

The invention relates to a preparation method of composite phase change coating fabric for cold-proof gloves and belongs to the technical field of functional fabric. The composite phase change coatingfabric for the cold-proof gloves is prepared by adding polyacrylate to wrap paraffin phase change microcapsules, the microcapsule technology is a technology for wrapping a solid or liquid material with a film forming material to obtain core-shell structure particles, capsule walls provide a stable enclosed environment for the phase change material, the stability of the phase change material can be enhanced, meanwhile, solid-liquid phase change can be changed into solid-solid phase change, the phase change material is composited with fiber and textile more easily, the phase change material isdispersed into small particles and thus has better thermal conductivity, the specific surface area of the phase change material can be obviously increased by the microcapsule technology, phase separation and supercooling can be eliminated, and the durability and service life can be prolonged.

Description

technical field [0001] The invention relates to a preparation method of a composite phase-change coating fabric for cold-proof gloves, belonging to the technical field of functional fabrics. Background technique [0002] The human body often reduces heat loss by reducing the local blood circulation of the human body in a cold environment. Hands and feet are far away from the heart, and the blood circulation function is reduced in a cold environment. Because of their small output, their heat balance is almost completely dependent on blood circulation transmission, and improper protection can easily cause frostbite. Hand dexterity and tactile sensitivity decrease during hand temperature reduction and the risk of accidents increases. When the hand temperature is <4.4°C, the hand completely loses the ability of fine work; when the temperature is between 4.4 and 12.8°C, the tactile discrimination ability of the hand drops significantly; when the temperature is >15.6°C, the...
