内蒙古工业大学本科毕业论文本科毕业论文题目：羊毛/蚕丝混纺织物一浴法染色同色性研究学生姓名：刘广增学院：轻工与纺织学院系别：纺织工程系专业：纺织工程班级：纺织工程11-2指导教师：王利平教授二〇一五年六月学校代码：10128学号：201121803054内蒙古工业大学本科毕业论文摘要本文的目的是研讨羊绒/蚕丝混纺织物同浴染色后同色性的效果。在羊绒/蚕丝同浴染色过程中的困难在于羊绒和蚕丝在形态结构、物理特性和化学组成上差异非常大，这些差异一定会使这两种纤维在染色过程中有鲜明的差异。经过对羊绒、蚕丝的外观、内部结构和物理化学性状能力开始剖析，对染料品种的选用、助剂的用量及染色工艺条件等几个方面对羊绒/蚕丝的染色工艺进行了探究，并且初步认为：（1）对羊绒/蚕丝染色前的处理过程中，不管是纤维化学分子发生交链键合，还是其内部构造产生结构转化，纤维的疏水水平都相应的增加了，所以染色时应该选用元明粉做膨化剂，阿白格做匀染剂，以提高这两种纤维的同色性；（2）选用30g/L左右的渗透剂，1%左右的匀染剂对于羊绒/蚕丝染深颜色以及提高纤维的同色性也非常重要；（3）采用疏水性能比较强、分子量相对较大的活性染料，这样不但能可以效地提高纤维的同色性，还能使纤维的色牢度相应上升。针对羊绒/蚕丝同浴染色过程中这两种纤维存在色差的原因，参照羊绒/蚕丝混纺纱线同色性的色差标准，在染色工艺条件方面做了一定的实验，而且确定了羊绒/蚕丝混纺纱线同浴染色过程中相对较好的染色工艺条件。关键词：同浴染色；同色性；染色工艺内蒙古工业大学本科毕业论文AbstractInthispaper,cashmere/silkblendfabricdyeingbathafterproblemswiththesamecolor.Difficultyincashmere/silkbathdyeingprocessiscashmereandsilkintheformofstructure,physicalpropertiesandchemicalcompositionareverydifferent,thesedifferenceswillmakethesetwofibershaveadistinctdifferenceinthedyeingprocess.Bycashmere,silkappearance,internalstructureandphysicalandchemicalpropertieswereanalyzedseveralaspectsofthechoiceofthetypeofdye,theamountofaidandconditionsondyeingcashmere/silkdyeingwerestudied,andthepreliminaryviewthat:(1)fortheprocessingofcashmere/silkbeforedyeing,whetheritisfiberchemicalmoleculescross-linkedbond,oritsinternalstructureandstructuretransformation,hydrophobicityofthefibersincreasescorrespondingly,soitshouldbethechoiceoftheYuanandMingstainingPowderofbulkingagent,Awhitecellsdolevelertoimproveboththefibersofthesamecolor;(2)usepenetrant30g/Lorso,about1%oflevelingagentforcashmere/silkdyeddarkcolorandincreasefiberofthesamecolorisalsoveryimportant;(3)theuseofrelativelystronghydrophobicproperty,arelativelylargemolecularweightreactivedyes,sonotonlycaneffectivelyimprovethefiberofthesamecolor,butalsotoacorrespondingincreaseinfibercolorfastness.Forthesetworeasonsforthepresenceoffiberscolorcashmere/silkbathdyeingprocess,thesamecolorstandardcolorinthedyeingprocessconditionsmadesomeexperimentswithreferencecashmere/silkblendedyarn,anddeterminesthecashmere/silkblendslinewiththebathdyeingprocessbetterdyeingprocessconditions.Keywords:bathdyeing;samecolor;dyeing内蒙古工业大学本科毕业论文目录引言.................................................................1第一章活性染料染色原理及展望..........................................21.1活性染料...........................................................21.2活性染料的染色原理..................................................21.3活性染料染羊绒纤维.................................................31.4活性染料染蚕丝纤维.................................................31.5研究现状............................................................41.6创新型研究..........................................................5第二章羊绒/蚕丝的结构与性能...........................................62.1羊绒的组成与结构....................................................62.1.1组成.......................................................62.1.2结构.......................................................62.2羊绒的物理化学特性..................................................72.2.1物理特性...................................................72.2.2化学特性...................................................72.3蚕丝的特点..........................................................82.4蚕丝的结构..........................................................92.4.1蚕丝的组成.................................................92.4.2蚕丝的结构.................................................92.5蚕丝的性能.........................................................102.5.1物理性能..................................................102.5.2化学性能..................................................11第三章羊绒蚕丝混纺织物同浴染色.......................................133.1实验材料及药品.....................................................133.2实验仪器....................................................133.3评定标准...........................................................143.4染色工艺...........................................................143.4.1染色工艺流程..............................................14内蒙古工业大学本科毕业论文3.4.2元明粉....................................................143.4.3PH值......................................................153.4.4浴比......................................................173.4.5温度......................................................183.4.6保温时间..................................................203.4.7染料浓度..................................................233.5正交实验...........................................................243.5.1正交试验简介..............................................243.5.2正交试验步骤..............................................253.5.3正交试验设计..............................................26结论..................................................................33参考文献..............................................................34致谢..................................................................36内蒙古工业大学本科毕业论文1引言虽然大部分的羊绒制品都被加工成了高档的消费产品，但是现代的消费观念还是驱使人们购买这类产品。所以，我国的羊绒制品行业在我国的消费份额中占很大的比例，对于研发新的羊绒产品尤为重要。由于羊绒纤维细度细、强力低，纺高支纱困难，从而使得羊绒制品难以向轻薄化发展，同时，纯羊绒制品的原料成本较高，难以被更广大的消费者所接受[1]。从羊绒产品自身的实用方面来考虑，并不是像大多数人们所认知的羊绒的含量较高时质量就会较好，而是应该适当添加一些性能较好的纤维进行混纺
