生物质变色染料合成及对涤/棉混纺织物的同浴一步染色
Synthesis of biomass color-changing dyestuff and one-step dyeing of polyester/cotton blended fabrics in the same bath
摘要
Abstract
The global textile industry is accelerating its transition towards green,low-carbon,and sustainable development,within which the clean transformation of the dyeing and finishing sector is crucial.Traditional synthetic dyes,valued for their vivid colors,excellent color fastness,and low cost,are widely used in the textile industry.However,their production and application cause significant environmental pollution,hindering the industry's sustainable development.Consequently,developing novel eco-friendly dyes to replace traditional synthetic dyes has become an urgent priority.Biomass dyes are natural colorants derived from renewable biological resources(such as plants,animals,microorganisms,agricultural and forestry waste)through physical extraction or green chemical conversion processes.Compared to traditional synthetic dyes,biomass dyes offer superior biodegradability and environmental friendliness,aligning with the principles of green chemistry and sustainable development.However,conventional biomass dye applications are mostly limited to fabric coloration,failing to meet the growing demand for stimuli-responsive smart textiles.This has spurred increasing research interest in developing intelligent responsive biomass dyes.Specifically,biomass color-changing dyes have garnered significant attention due to their inherent eco-friendliness and environment-responsive color-changing capabilities.Studies have shown that external stimuli like temperature,pH,light,and electricity can trigger color changes in these smart dyes.pH-responsive color-changing dyes,in particular,hold immense potential in sensing,detection,healthcare,and information encryption.Nevertheless,existing biomass color-changing dyes face drawbacks such as complex synthesis routes,high costs,dependence on specific equipment,and insufficient stability in key performance metrics.Therefore,developing a simple,green synthesis process to produce stable biomass color-changing dyes is of significant value. Polyester/cotton(T/C)blend fabrics dominate the textile market by combining polyester's durability with cotton's comfort.However,the vastly different chemical properties of the warp and weft fibers necessitate complex dyeing processes.Traditional methods typically involve either two-bath two-step or one-bath two-step procedures,dyeing the polyester and cotton fibers separately.This not only increases dyeing costs but also significantly raises energy consumption.Furthermore,these methods often require large amounts of salt-based accelerants,substantially increasing the environmental burden of the dyeing process.Recent advances include novel dyeing technologies like the one-bath one-step method,which has become a research focus due to its potential to drastically shorten dyeing time,reduce energy consumption,and minimize environmental pollution.However,practical application still faces challenges,such as the need for pre-treatment of T/C fabrics,demanding dyeing conditions,and incomplete resolution of water pollution issues.Thus,developing an efficient and eco-friendly dyeing method suitable for T/C blend fabrics is essential. We synthesized a pH-responsive biomass intelligent color-changing dye(BICD)from biomass raw materials under mild and simple conditions.The dye exhibits reversible color change:it appears purple at pH14 and orange at pH1.Additionally,it demonstrates good solubility in alkaline environments but poor solubility in acidic environments.Leveraging this property,we developed a salt-free acid fixation technique for the one-bath one-step dyeing of T/C blend fabrics.The optimal dyeing process parameters were determined through comparison and screening(BICD dosage:1%owf;CA concentration:1 mol/L;dyeing temperature:25℃;and dyeing time:4 hours).We systematically evaluated the color fastness,breathability,and mechanical properties of the dyed material(BICD@T/C)and assessed the coloring efficacy of the salt-free acid fixation technology on the T/C fabric.Furthermore,we investigated the pH-stimulated color-changing characteristics and ultraviolet(UV)protection functionality of BICD@T/C and explored its application in the visual detection of alkaline gases.关键词
