热变色织物的制备及其热响应机制与储能性能研究
A study on the preparation of thermochromic fabrics and their thermal response mechanism and energy storage properties
摘要
Abstract
Reversible thermochromic textiles exhibit dynamic thermal-responsive color changes,offering significant application potential in smart textiles,wearable devices and medical monitoring.Currently,integrating thermochromic microcapsules with fabrics or fibers via microencapsulation technology has become one of the primary approaches for developing thermochromic textiles.Common processing methods include printing,coating and thermochromic fiber weaving.Specifically,screen printing is widely preferred due to its simplicity,ease of operation and flexible pattern design,making it an optimal technique for achieving patterned thermal-responsive effects on textiles. Poly ester/cotton blended fabrics were selected as the substrate due to their excellent combined properties.The polyester component provides high strength,durability and wrinkle resistance,while the cotton component ensures good moisture absorption and breathability,offering a balanced combination of functionality and comfort.Additionally,the twill weave structure further enhances the fabrics' abrasion resistance and wrinkle resistance,endows it with a desirable three-dimensional texture and facilitates uniform adhesion of the printing paste,contributing to clear pattern edges and vivid thermochromic effects. Based on this,this study utilized screen printing to fabricate thermochromic textiles with excellent thermal responsiveness and energy storage performance.The effects of sodium alginate,crystal violet lactone-based thermochromic microcapsules and waterborne polyurethane adhesive on the properties of the printing paste and the final printing quality were investigated.The thermal-responsive color change behavior and thermal energy storage performance of the printed fabrics were also analyzed.Experimental results demonstrated that when the mass concentrations of sodium alginate,polyurethane adhesive and reversible thermochromic microcapsules were 2％,6％and 10％,respectively,the prepared thermochromic fabrics exhibited good colorfastness and uniform surface quality.The color change temperature range of the thermochromic microcapsules was 35-38 ℃,making them suitable for body temperature monitoring.During heating and cooling cycles,the core material inside the microcapsules underwent a reversible color change through the crystallization-melting cycle of the eutectic phase.After 50 thermal cycles,the thermochromic fabric still maintained rapid,stable and reversible thermal response performance.Additionally,the fabric exhibited a certain degree of thermal energy storage,providing localized insulation during temperature changes. This study confirmed the feasibility of applying thermochromic microcapsules to polyester/cotton fabrics via screen printing,providing technical support for the development of thermochromic textiles in smart wearable temperature sensing and personalized thermal-responsive applications.However,challenges remain in improving the durability,environmental stability and response speed of the microcapsules.Future work may focus on optimizing microcapsule wall materials,enhancing interfacial bonding,and improving washing and abrasion resistance to further expand the application potential of thermochromic textiles in multifunctional smart textile fields.关键词
