【摘要】：近年来,经济的快速发展使人们的生活发生了翻天覆地的变化,人们对生活质量的要求也在不断提高,尤其是对被视为“第二皮肤”的服装,为了满足人们的需求,各种功能性服装应运而生。“调温服装”就是新兴功能服装中发展最快且最受欢迎的一类,它是将相变材料与织物结合开发的一种功能服装,服装中的相变材料可以根据温度变化发生固-液或固-固的可逆变化,且变化过程中会伴有热量的吸放,这种吸放热过程是自动的、可逆的、无限循环的,因此具有双向调温功能。调温服装有利于保持人体表面温度,使人体在穿着舒适的同时还能减少空调能耗,符合现代社会“低碳环保”的要求。聚乙二醇(PEG)是相对分子量介于一定范围内的聚合物,其可在一个冷热循环过程中发生相变,因此本课题选择PEG作为相变材料来开发智能调温面料。在课题研究过程中,首先采用DSC测试方法,对单一相变材料PEG-600(试剂)、PEG-800(试剂)、PEG-1000(试剂)、PEG-1000(药用)、PEG-1500(试剂)的相变温度和相变焓进行测试研究,通过对DSC图谱分析得知试剂PEG-600的相变温度为9.85℃,相变焓为91.5J/g;试剂PEG-800的相变温度为47.7℃,相变焓为194.8J/g;药用PEG-1000的相变温度为41.7℃,相变焓为176.7J/g;试剂PEG-1000的相变温度为48.05℃,相变焓为155.65J/g;试剂PEG-1500的相变温度为45.8℃,相变焓为178.95J/g。通过施罗德公式计算得到不同PEG复合时的理论最低共熔点,经过大量试验,最终确定选用试剂PEG-800与药用PEG-1000作为单一相变材料来制备相变温度在31~33℃范围的复合相变材料,试剂PEG-800与药用PEG-1000的最佳复配比为1:9。本课题研究的重点是选用2D树脂作为交联剂,对棉织物和涤/棉织物的交联工艺进行研究和分析。由于增重量对织物热活性影响较大,而2D树脂会使织物强力下降,因此以织物增重率和强降率作为评价指标,采用单因素分析法对2D树脂用量、催化剂Mg Cl2·6H2O/柠檬酸摩尔分数比、焙烘温度、焙烘时间进行分析,通过正交试验分析法确定棉织物的最佳交联工艺为:2D树脂60g/L,Mg Cl2·6H2O/柠檬酸(10g/L)摩尔分数比8:1,焙烘温度为140℃,焙烘时间为3min,浴比1:20;确定涤/棉织物的最佳交联工艺为:2D树脂30g/L,Mg Cl2·6H2O/柠檬酸(3g/L)摩尔分数比6:1,焙烘温度为140℃,焙烘时间为165s,浴比1:20。对交联后棉织物和涤/棉织物的物理机械性能、热湿舒适性、热活性等进行测试。具体包括织物厚度、单位面积重量、顶破强力、透气性、透湿性、吸水性、保温性、相变温度、相变焓等。最后得出:经过PEG、2D树脂整理后的织物满足针织物服用性能的要求,且整理后的织物具有一定的调温区间,能起到一定的调温作用,因此适合开发具有调温功能的针织面料。
[Abstract]:In recent years, with the rapid development of economy, people's life has changed dramatically, and people's requirements for quality of life are also increasing, especially for the clothing which is regarded as "the second skin". In order to meet the needs of people, a variety of functional clothing came into being. "temperature-adjusting clothing" is the fastest growing and most popular type of new functional clothing. It is a kind of functional garment developed by combining phase change material and fabric. The phase change material in clothing can produce the reversible change of solid liquid or solid solid according to the change of temperature, and it will be accompanied by heat absorption and desorption during the process of change. This heat absorption and release process is automatic, reversible, infinite circulation, so it has the function of bidirectional temperature adjustment. Temperature adjustment clothing is conducive to maintain the body surface temperature, so that the human body can wear comfortable while also reduce the energy consumption of air conditioning. Polyethylene glycol (PEG) is a polymer with relative molecular weight in a certain range, which can undergo phase transition during a cold and hot cycle. Therefore, PEG is chosen as phase change material to develop intelligent temperature-regulating fabric. In the course of the research, the single phase change material PEG-600 (reagent) is first tested by DSC. The phase transition temperature and enthalpy of PEG-800 were measured. The DSC spectra showed that the phase transition temperature and enthalpy of PEG-600 were 9.85 鈩，
