1、棉織物由于價廉物美、吸濕性好、穿著舒適等優(yōu)點而倍受人們喜 愛，但是棉織物對微生物低劣的抵抗性使其廣泛應(yīng)用遇到一定的挑戰(zhàn)。 隨著人們生活水平的提離和健康環(huán)保意識的增強，對紡織品衛(wèi)生保健 功能的要求越來越高，因此對棉織物進行抗菌整理具有十分垂要的意 義。在各種抗菌劑中，納米氧化鋅的抗菌效果非常好，還具有廣譜抗 菌、高效持久、對人體無毒無刺激等優(yōu)點，因此本論文主要研究了納 米氧化鋅抗菌劑的制備并對棉織物進行抗菌整理使之獲得良好的抗菌 性能。由于納米材料的特殊效應(yīng)，使得納米抗菌劑的性能遠比傳統(tǒng)抗菌 劑要優(yōu)越。市售的納米抗菌劑產(chǎn)品多為粉末狀的，對織物進行抗菌整 理時必須先將其配成抗菌劑顆粒均勻分散的溶液

2、。前人己有的研究表 明，由于納米微粒之間吸附作用很強，非常容易發(fā)生團聚，使得抗菌 劑顆粒無法在織物上均勻分布，高溫焙烘后抗菊劑粉體又很容易從織 物上脫落，嚴(yán)重影響了織物的抗菌效果。針對這個問題，本課題基于 文獻綜述中無機抗菌劑的優(yōu)點，選擇了 ZnO為無機抗菌劑.納米氧化 鋅的抗菌性能來源于光催化活性及金屬離子溶出機理，綜合比較了 ZnO 制備方法的優(yōu)劣，再結(jié)合科研實際情況，本辣題選擇了 ZnCb、NaOII、 聚丙烯酸納(PAAS)、？ 一縮水甘油瞇氧丙基三甲氧基硅烷(GPTMS) 等為基本原料，采用了微乳法和溶膠一凝膠法配制了 ZnO溶膠，并用 XRD和Zetar激光粒度儀進行檢測和表征；在

3、不影響棉織物手感的前 提下，采用浸軋烘抗菌整理工藝使ZnO溶膠負(fù)載在棉織物上，并以富 有代表性菌種的革蘭氏陰性菌種大腸桿菌和革蘭氏陽性歯種金黃色葡 萄球菌為代表菌種，采用抑菌圈法進行檢驗，并以二次通用旋轉(zhuǎn)組合 設(shè)計方法設(shè)計實驗方案進行實驗，優(yōu)化參數(shù)，以得到最佳抗菌工藝條 件；用掃描電鏡比較分析了棉織物原樣與處理樣的表面結(jié)構(gòu)變化，并 探討了納米ZnO的抗菌機理及用ZnO處理棉織物后對其基本物理性能 的影響；最后附帶探討了經(jīng)ZnO溶膠處理后的棉織物抗紫外線的研究。 本課.題最終得到如下的結(jié)論：1經(jīng)XRD、ZeTar激光粒度對ZnO溶膠表征和檢測后，發(fā)現(xiàn)大多數(shù)ZnO 粒子的大小在77.6nm左右，這

4、說明納米氧化鋅的粒度粒徑已經(jīng)達到 了納米級。在對納米氧化鋅溶膠制備的影響因素的探討中，經(jīng)實驗 證明在下列條件中，制得的氧化鋅水溶膠是均勻和穩(wěn)定的：r值（HQ 與金屈醇鹽的摩爾比）為40、PH值為6、溫度為609。2用ZnO溶膠對棉織物進行傳統(tǒng)的浸軋烘抗菌整理工藝，并采用二次 通用旋轉(zhuǎn)組合設(shè)計方法，利用隨機方向搜索法，得到大腸桿菌和金 黃色葡萄球菌最優(yōu)抗菌工藝參數(shù)。ZnO溶膠濃度5.7600%、溫度為 44.6671* Cx 時間為 45.0226 分鐘，PH 為 6。3從掃描電鏡測試圖中可知，抗菌整理前后棉織物的表面形態(tài)發(fā)生了明 顯的變化，經(jīng)過抗菌整理的棉布樣上均勻分散著許多非常微細的納米 Z

5、nO顆粒。這說明納米氧化鋅在應(yīng)用在棉織物上時并沒有發(fā)生明顯的 團聚現(xiàn)象；處理后的棉織物的水洗50次后，耐水洗性效果仍然良好; 對經(jīng)納米ZnO整理的棉織物進行抗菌性機理的探討后可知:納米ZnO 對棉織物的抗菌性能是由光催化機理和金屬離子溶出機理共同起作 用的結(jié)果。4經(jīng)實驗后，發(fā)現(xiàn)經(jīng)納米ZnO溶膠處理后的棉織物對其物理基本性能 有所彩響：棉織物潤濕性和透氣性幾乎沒有什么變化，白度略微增 加，斷裂強力、褶皺回復(fù)角略有降低，但是這些變化在實際使用中 是可以接受的。5在納米ZnO對棉織物抗紫外線的研究中，實驗結(jié)果發(fā)現(xiàn)在波長280 400nm范圍內(nèi)，紫外線中UVA和UVB的透過率都很小，透過率分 別為1.

6、34%和2.08%, UPF為49.714。這說明整理后的棉織物具有 非常好的抗紫外線的作用。關(guān)鍵詞：棉織物，納米ZnO,抗菌劑，抗菌，抗紫外線Nanometer Antibacterial MaterialsTrepration AndExploration On TextilesApplicationABSTRACTIn the modem life ,cotton fabrics are more and more popular because of their excellent absorptance and wear-comfort,but they have poor micr
