本科毕业论文题目:棉织物热转印工艺分析学生姓名:魏超学院:轻工与纺织学院系别:印刷工程系专业:印刷工程班级:印刷13-1班指导教师:王丽珍学校代码:10128学号:201321811022二〇一七年六月摘要由于棉织物热升华转移印刷工艺的应用和个性化需求不断增加,热转印这一传统工艺又重获朝气。棉织物热转印工艺参数的设定以及织物材料的选择没有统一的标准,所以本文对热转印的理论和实际操作进行一次综合的研究。本文通过设计多因素、多水平的正交实验,研究了热转印温度、时间和压力三个工艺参数对油墨的转移率,表观深度K/S值,皂洗牢度的影响,以及针对棉织物材料合理选择热转印方式。经过数据的分析获得最优工艺方案,为棉织物热升华热转印这一工艺实际操作提供一定的数据参考依据。本论文研究热转印的背景、现状,前景以及它的优缺点。对热转印工艺的特点、工艺参数以及耗材进行了一次概述,然后对本次实验的所用的正交实验做了认真的理论分析,通过理论与实验相结合得到一个棉织物热转印工艺的最优方案。关键词:棉织物热转印;油墨转移率;正交实验AbstractThankstotheincreasingapplicationandpersonalisationofthetransferprintingprocessofcottonfabric,thetraditionalprocessofheattransferprintingisrenewed.Cottonfabricsthermaltransferprocessparametersettingandthechoiceoffabricmaterialthereisnouniformstandard,sointhispaper,theheattransfertheoryandpracticaloperationonacomprehensivestudy.Thisarticlethroughthedesignofmultiplefactorsandlevelsorthogonalexperiment,tostudytheheattransfertemperature,timeandpressurethreeprocessparametersontheprintinginktransferrate,apparentdepthK/Svalue,soapingfastness,aswellasreasonableselectionforcottonfabricmaterialthermaltransfermode.Throughtheanalysisofthedata,theoptimalprocessschemeisobtained,whichprovidessomedatareferencebasisforthepracticaloperationofheattransferprintingofcottonfabric.Thispaperstudiesthebackground,presentsituation,prospectanditsadvantagesanddisadvantagesofheattransfer.Tothecharacteristicsofheattransferprocess,processparametersandmaterialhadanoverview,thenforthisexperimentusedtheorthogonalexperimentwasadoptedtodoserioustheoreticalanalysis,acottonfabricisobtainedbycombinationoftheoreticalandexperimentalheattransferprocessoftheoptimalsolution.Keywords:Heattransferofcottonfabric;ratioofprintinginktransfer;orthogonalexperiment目录第一章概述.............................................................11.1课题研究背景....................................................11.2课题研究现状....................................................11.3课题发展趋势....................................................21.3.1无纸转印技术..............................................21.3.2热转印纸的重复使用........................................31.3.3数码热升华转印技术........................................31.4课题研究目的....................................................41.5课题研究的内容..................................................4第二章理论分析.........................................................52.1正交实验理论分析................................................52.1.1等水平正交表设计..........................................52.1.2正交实验的基本步骤........................................62.1.3多指标正交实验结果分析....................................72.1.4正交实验小结..............................................72.2热转印基础理论..................................................82.2.1热转印的特点..............................................82.2.2热转印材料................................................92...
