摘要
利用一定浓度的铜氨溶液处理竹浆纤维,使之形成铜氨离子络合竹浆纤维,并进行抗菌实验.通过改变铜氨溶液的反应浓度,在保证原有力学性能基本不变的前提下,确定尚不足以溶解纤维素的临界浓度;研究了反应时间和处理浴比等因素对铜离子结合量与络合平衡的影响.结果表明:竹浆纤维本身不具有抗菌性,经处理后的铜氨离子络合竹浆纤维具有很好的抗菌性;铜氨溶液处理浓度达到0.05 mol/L以上时,力学性能开始下降;铜离子结合量在初始阶段随着反应时间和浴比的增加而显著增大,但达到络合平衡以后变化不大.
The bamboo pulp fabrics was endowed with antibacterial activity.To obtain the objective,the bamboo plup fabrics was treated by the copper liquor in the lower concentration,which could react with cellulose in metal complex style and form Cu（Ⅱ） complex bamboo pulp fabrics.Critical concentration of the copper liquor that can not dissolve the cellulose at least was obtained in the condition that mechanical property do not change via the variety of reactiion concentrations.The factors of reacting time and bath ratios were used to study the impact of the equilibrium of the metal complex and the quantity combined with Cu（Ⅱ）.The results showed that bamboo pulp fabrics did not hold antibacterial performance,but the Cu（Ⅱ） complex bamboo pulp fabrics possessed it.The mechanical property started to decline when the critical concentration was above 0.05 mol/L.The quantity combined with Cu（Ⅱ） increasd smoothly with the increase of reacting time and bath ratios at first,and it changed little when the equilibrium was established.So the optimum reacting conditions were obtained and it could be referred in the future.
