牛仔布前处理染色一浴法工艺探讨VIP免费

摘要本文主要对牛仔布前处理染色一浴法进行可行性研究。通过分析比较前处理后牛仔布的白度、毛效和强力以及还原染料染色后牛仔布的K/S值大小、摩擦牢度和皂洗牢度的高低，得到较佳双氧水浓度、氢氧化钠浓度、精炼剂浓度、还原剂浓度、还原染料用量、烧碱用量及处理时间。优选适用于实际生产的一浴法工艺流程，并将一浴法、两浴法和传统工艺的性能作比较，从而达到现代生产实际所提倡的清洁生产、节能减排理念。关键词牛仔布；前处理；染色；一浴法；还原染料AbstractThejean’spretreatmentanddyeinginone-bathprocesswasstudiedinthepaper.Thepreferredhydrogenperoxidesolutionconcentration，thesodiumhydroxideconcentration，therefiningagentconcentration，thereducingagentconcentrationordosage,thevatdyedosage,thecausticsodadosageandtime,whichwasobtainedbyanalyzingandcomparingthewhiteness,thecapillaryeffectandthebruteforceafterthejean’spretreatmentandtheK/Svalue,thecolorfastnesstocrockandthelaunderingcolorfastnessofdyedjeanwithvatdyes.Thebestinone-bathprocesswasselectedtoactualproduction,andthepropertyofinone-bathprocesswascomparedtointwo-bathprocessandtraditionalcraft.Consequently,thetheoryofthecleanerproductionandtheconserveenergyandcutemissionwereachieved.Keywordsjean;pretreatmentanddyeing;inone-bathprocess;vatdye目录摘要.............................................IAbstract............................................II第1章绪论...........................................11.1课题研究的目的和意义...................................................11.2国内外研究现状.........................................................11.3主要研究内容...........................................................2第2章理论部分.........................................32.1棉织物练漂和还原染料染色的传统工艺及其机理.............................32.1.1棉纤维的结构和性能.................................................32.1.1.1棉纤维素.........................................................32.1.1.2蜡状物质.........................................................42.1.1.3果胶质...........................................................42.1.2还原染料的结构.....................................................42.1.3牛仔布前处理和还原染料染色工艺.....................................52.1.3.1前处理...........................................................52.1.3.2还原染料染色过程.................................................52.1.4靛蓝染料染色的注意事项.............................................62.2.牛仔布还原染料练染一浴的理论探讨.......................................62.2.1还原染料一浴法染色理论基础.........................................62.2.2牛仔布前处理和还原染料染色一浴法中的问题...........................62.3本章小结...............................................................7第3章实验部分.........................................83.1实验材料和仪器设备.....................................................83.2测试方法...............................................................83.3工艺流程...............................................................93.3.1传统工艺流程.......................................................93.3.2两浴法工艺流程.....................................................93.3.3前处理和染色一浴法工艺流程.........................................93.4实验内容...............................................................93.4.1前处理工艺探讨.....................................................93.4.1.1不同浓度的双氧水对...
