紫外线与温度协同感应变色凉爽织物的制备及性能
Preparation and properties of UV and temperature synergistic induction color-changing cool fabrics
摘要
Abstract
In view of the intelligent,environmental protection and functional requirements of summer textiles,intelligent textiles that integrate the cool-feeling effect and the color-changing function of common induced conditions such as ultraviolet light and temperature are developed by combining color-changing microcapsules and cool-feeling fabrics.They broad application prospects in the field of functional clothing. A breathable and cool woven fabric was developed by using ordinary polyester yarn as the warp yarn and PE/PA,cool polyester and cool nylon filament as the weft yarn.The effects of weft raw materials,weft density and weave structure on the wearability of the fabric were investigated.The fabric with the best comprehensive performance was selected by fuzzy mathematics and the screen printing discoloration coating was carried out,which had both cooling feeling and UV and temperature discoloration effect.The effects of binder concentration,baking temperature and baking time on the wearability were investigated,and the best preparation process was finally selected.The results show that the coolness coefficient of PE/PA silk fabric was higher;the cool feeling polyester fiber had good air permeability;the stiffness value of cool nylon wire was the smallest.The contact coolness and stiffness of the fabric increased with the increase of weft density,and the air permeability decreased with the increase of weft density.The coolness,air permeability and softness of satin weave were the best.Y6 cool nylon satin fabric had the best comprehensive performance,which can be attached to the surface by thermal/photochromic microcapsules to give the fabric discoloration function.At room temperature,the fabric was red;when only ultraviolet light was sensed,the fabric was purple red;only when the temperature was induced,the fabric was yellow;during temperature/ultraviolet synergistic induction,the fabric changed to green.The discoloration effect was obvious,the color was clear,and the multi-level discoloration was realized.The thermochromic and photochromic microcapsules had good sensitivity,and the discoloration/fading response speed of the color-changing cool fabric was faster than that of the ordinary color-changing fabric.After 100 cycles of testing,the fabric still had good thermal/light reversibility and durability.The dry friction resistance of the color-changing cool fabric was grade 5,and the wet friction resistance and soaping resistance grade increased with the increase of the binder concentration.The stiffness of the fabric decreased first and then increased with the increase of the binder concentration.The finished fabric still had good softness and good air permeability and moisture permeability.By combining the results of grey comprehensive evaluation and orthogonal analysis,the optimum process for preparing color-changing and cool-feeling fabrics was optimized as follows:the concentration of adhesive was 25%,the baking time was 5min,and the baking temperature was 120℃. A smart fabric with both coolness and temperature/ultraviolet dual response discoloration was developed by combining color-changing materials with cool fabrics.The fabric improves the adaptability of the human body to the thermal environment,saves energy and protects the environment,and timely feedbacks the skin temperature,which provides an important reference and basis for the development of multifunctional intelligent textiles.关键词
