Abstract

The invention provides a microcapsule finishing agent for cool and refreshing functional fabric. Polystyrene is used as a wall material, n-tetradecanol and mint essence are used as a composite core material, mass fraction of the mint essence is 5-20% of total mass of the core material, and a mass ratio of the core material to the wall material is 1-3:1. The invention further provides a preparation method of the microcapsule finishing agent. The preparation method includes: mixing n-tetradecanol, the mint essence, a dispersant, an emulsifier, a crosslinking agent and distillated water, homogenizing, and then performing water bath; adding styrene and an initiator into an emulsifying system, and performing prepolymerization and polymerization sequentially under protection of nitrogen; after reaction is finished, suction-filtering, washing, and drying to obtain the microcapsule finishing agent. N-tetradecanol and the mint essence are wrapped, the characteristics that phase transformation point of n-tetradecanol is close to human normal body temperature and latent heat of phase transformation is high are utilized, heat released in the process of phase transformation of n-tetradecanol is conducive to the mint essence to emit special faint scent and present coolness.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and relates to a finishing agent, in particular to a microcapsule finishing agent for cooling and toning functional fabrics and a preparation method thereof. Background technique [0002] The so-called phase change material refers to a temperature control material that changes its state or structure within a specific temperature range (that is, the so-called phase change range) to realize thermal energy storage and release. Microcapsule phase change material is a new type of phase change material with a core-shell structure formed by coating the surface of the phase change material with a layer of stable polymer film using microcapsule technology. Compared with ordinary phase change materials, microcapsule phase change materials improve the use efficiency of phase change materials, broaden the application fields of phase change materials, and effectively solve the problems of easy leaka...
