摘要： 染料在日常生活中应用广泛，但公众对其织染及化学知识了解甚少。本实验以天然染料(姜黄粉、五倍子粉)和合成染料(直接蓝71、活性红2)为媒介，展示直接、媒染、反应性三种染色过程，对比不同酸碱条件下织染物的颜色变化，考察织染稳定性。实验联系生活，由浅及深传播知识，提高公众科学素养，过程简单易操作，易推广。

Abstract: While dyes permeate daily life, public understanding of their application chemistry remains limited. This experimental study employs natural dyes (turmeric and gallnut powders) alongside synthetic counterparts (Direct Blue 71 and Reactive Red 2) to demonstrate three distinct dyeing mechanisms: direct application, mordant-assisted, and reactive dyeing processes. The investigation systematically examines colorimetric variations in dyed textiles under controlled pH conditions, with particular emphasis on dye stability assessment. Designed as an accessible public outreach initiative, this experiment progresses from fundamental concepts to advanced applications, effectively bridging chemical principles with practical textile technology while promoting scientific literacy through reproducible, user-friendly protocols.
