【摘要】：近年來,經(jīng)濟(jì)的快速發(fā)展使人們的生活發(fā)生了翻天覆地的變化,人們對(duì)生活質(zhì)量的要求也在不斷提高,尤其是對(duì)被視為“第二皮膚”的服裝,為了滿足人們的需求,各種功能性服裝應(yīng)運(yùn)而生。“調(diào)溫服裝”就是新興功能服裝中發(fā)展最快且最受歡迎的一類,它是將相變材料與織物結(jié)合開發(fā)的一種功能服裝,服裝中的相變材料可以根據(jù)溫度變化發(fā)生固-液或固-固的可逆變化,且變化過程中會(huì)伴有熱量的吸放,這種吸放熱過程是自動(dòng)的、可逆的、無限循環(huán)的,因此具有雙向調(diào)溫功能。調(diào)溫服裝有利于保持人體表面溫度,使人體在穿著舒適的同時(shí)還能減少空調(diào)能耗,符合現(xiàn)代社會(huì)“低碳環(huán)�！钡囊�。聚乙二醇(PEG)是相對(duì)分子量介于一定范圍內(nèi)的聚合物,其可在一個(gè)冷熱循環(huán)過程中發(fā)生相變,因此本課題選擇PEG作為相變材料來開發(fā)智能調(diào)溫面料。在課題研究過程中,首先采用DSC測(cè)試方法,對(duì)單一相變材料PEG-600(試劑)、PEG-800(試劑)、PEG-1000(試劑)、PEG-1000(藥用)、PEG-1500(試劑)的相變溫度和相變焓進(jìn)行測(cè)試研究,通過對(duì)DSC圖譜分析得知試劑PEG-600的相變溫度為9.85℃,相變焓為91.5J/g;試劑PEG-800的相變溫度為47.7℃,相變焓為194.8J/g;藥用PEG-1000的相變溫度為41.7℃,相變焓為176.7J/g;試劑PEG-1000的相變溫度為48.05℃,相變焓為155.65J/g;試劑PEG-1500的相變溫度為45.8℃,相變焓為178.95J/g。通過施羅德公式計(jì)算得到不同PEG復(fù)合時(shí)的理論最低共熔點(diǎn),經(jīng)過大量試驗(yàn),最終確定選用試劑PEG-800與藥用PEG-1000作為單一相變材料來制備相變溫度在31~33℃范圍的復(fù)合相變材料,試劑PEG-800與藥用PEG-1000的最佳復(fù)配比為1:9。本課題研究的重點(diǎn)是選用2D樹脂作為交聯(lián)劑,對(duì)棉織物和滌/棉織物的交聯(lián)工藝進(jìn)行研究和分析。由于增重量對(duì)織物熱活性影響較大,而2D樹脂會(huì)使織物強(qiáng)力下降,因此以織物增重率和強(qiáng)降率作為評(píng)價(jià)指標(biāo),采用單因素分析法對(duì)2D樹脂用量、催化劑Mg Cl2·6H2O/檸檬酸摩爾分?jǐn)?shù)比、焙烘溫度、焙烘時(shí)間進(jìn)行分析,通過正交試驗(yàn)分析法確定棉織物的最佳交聯(lián)工藝為:2D樹脂60g/L,Mg Cl2·6H2O/檸檬酸(10g/L)摩爾分?jǐn)?shù)比8:1,焙烘溫度為140℃,焙烘時(shí)間為3min,浴比1:20;確定滌/棉織物的最佳交聯(lián)工藝為:2D樹脂30g/L,Mg Cl2·6H2O/檸檬酸(3g/L)摩爾分?jǐn)?shù)比6:1,焙烘溫度為140℃,焙烘時(shí)間為165s,浴比1:20。對(duì)交聯(lián)后棉織物和滌/棉織物的物理機(jī)械性能、熱濕舒適性、熱活性等進(jìn)行測(cè)試。具體包括織物厚度、單位面積重量、頂破強(qiáng)力、透氣性、透濕性、吸水性、保溫性、相變溫度、相變焓等。最后得出:經(jīng)過PEG、2D樹脂整理后的織物滿足針織物服用性能的要求,且整理后的織物具有一定的調(diào)溫區(qū)間,能起到一定的調(diào)溫作用,因此適合開發(fā)具有調(diào)溫功能的針織面料。
[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，
