摘　　要：该文设计了基于八甲基环四硅氧烷和不同类别硅烷偶联剂合成了不同结构的氨基硅油的综合实验,并对氨基硅油乳化和整理工艺进行了优化。使用紫外-可见分光光度计分析了氨基硅油乳液的透光性和稳定性,使用SEM和FTIR分析了样品的微观形貌和结构,使用测配色仪测试了织物的K/S值和增深效果。实验结果表明:氨基硅油乳液在HLB值为9时透光性和稳定性最好;增深整理的最佳工艺为QX-104基硅油乳液浓度100g/L、浸轧预处理时间5min、焙烘温度120℃、焙烘时间120s。该综合实验设计简单、普适性强,涉及有机合成、后整理工艺、结构表征和性能测试等知识点。结合单因素优化和对比实验能够为学生提供清晰的实验分析思路,强化所学知识,提升科研创新意识和实际动手能力。[Objective]An organosilicon color deepening agent has the characteristics of good emulsion stability,an environmentally friendly synthesis route,a good color deepening effect,and a good hand feel after fabric treatment.However,the formulated emulsion is generally unstable,and it will deteriorate and turn yellow owing to air oxidation and other problems.Therefore,it is essential to synthesize different structures of amino silicone oil based on different kinds of siloxane coupling agents and to compound suitable surfactants to emulsify into a stable,transparent microemulsion for fabric deepening finishing,which can give fabrics an excellent soft and smooth hand feel.[Methods]In this experiment,different structures of amino silicone oil are synthesized using octamethylcyclotetrasiloxane and various types of siloxane coupling agents,and their reaction processes and structure are characterized.The optimal emulsification conditions and deepening finishing process are studied through single-factor optimization and comparative experiments.Finally,performance testing is conducted on cotton fabrics with different textures and colors via an optimal finishing process to evaluate their dye depth and fastness levels.The transmittance and stability of amino silicone oil emulsions are analyzed with an ultraviolet–visible spectrophotometer.The microscopic morphology and structure of the samples are examined using scanning electron microscopy and Fourier transform infrared spectroscopy,and the K/S values and color deepening effects of the fabrics are measured with a colorimeter.[Results]The optimal light transmission and stability of the amino silicone oil emulsion are achieved at a hydrophilic–lipophilic balance(HLB)value of 9.The ideal process conditions for deepening finishing included an emulsion concentration of QX-104-based silicone oil at 100 g/L,a dip-rolling pretreatment duration of 5 min,a baking temperature of 120℃,and a baking time of 120 s.[Conclusions]A comprehensive experiment on the synthesis of amino silicon
