摘要：本論文針對氨基甲酸酯化后的滌棉織物，研究了氯漂時間、溫度、氯漂液PH值、濃度以及浴比等因素對氯漂后滌棉布上氯含量的影響，并對滌棉布上氯胺的穩(wěn)定性和可再生性進行研究。結(jié)果表明：隨著氯漂溫度的升高，氯含量減小，最佳氯漂溫度范圍為10℃以下；氯含量先增加后減少，在反應(yīng)到6min時最高；氯漂液濃度在0.75wt%之前，氯含量隨著濃度的增加而升高，且在0.5～0.75wt%之間增速逐漸變緩，在0.75wt%之后氯含量大幅下降，由此得到的最佳氯漂液濃度為0.5wt%；隨著溶液PH值的增加，氯含量也相應(yīng)變大，在PH=12時，氯含量最大；浴比對氯含量的影響很小，最佳浴比在1:70左右。氯漂后的滌棉在常溫下穩(wěn)定性較好，但經(jīng)過多次氯漂后可再生性不佳。改性后的織物對大腸桿菌和金黃色葡萄球菌均具有抗菌性，且抑菌率隨改性織物上氯含量增加而增加，當氯含量為1.32mg/g時，抑菌率達到了100%。 關(guān)鍵詞：滌棉織物，氨基甲酸酯，氯漂，氯胺，穩(wěn)定性，可再生性
Abstract：In this paper, it was studied that different effects of the chlorine bleaching were made on the chlorine content of the terylence/cotton fabric with different factors, such as the time of chlorine bleaching process, the temperature of chlorine bleaching solution, the PH value of chlorine bleaching solution, the concentration of chlorine bleaching solution, and bath ratio of the chlorine bleaching. The results showed that: with the temperature increasing, the chlorine content significantly declined, as a result, the best chlorine bleaching temperature was below 10℃. At the beginning of the experiment, the chlorine content increased gradually, and after 6minutes it dropped sharply, so, the best time of chlorine bleaching is 6minutes. When the concentration of the chlorine bleaching solution was below 0.75wt%, with the the concentration increasing, chlorine content went up with it. When the concentration of the chlorine bleaching solution was between 0.5~0.75wt%, the growth rate gradually slowed down. Afterwards chlorine content started to degrade, so, the best concentration of chlorine bleaching solution was 0.5wt%. With the increase of the solution PH value, the chlorine correspondingly became larger, when the PH hit 12, the chlorine content reached the peak, so it's obvious that the best solution PH value was 12. Throughout the experiment, bath ratio has little effect on the chlorine content and the best bath ratio was around 1:70. The terylence/cotton fabric chlorine bleached have a good stability under room temperature. But the regenerability of chlorine content became weak after several times of bleaching. Modified fabric has antibacterial property over E.coli and staphylococcus aureus and the antibacterical rate rises with the chlorine content. The antibacterical ratio reaches 100% when chlorine content was 1.32mg/g. Key words: terylence/cotton fabric, carbamate ,chlorine bleaching, chloramine, stability, regenerability.
