灰色聚类分析在牛仔布退浆工艺中的应用

Application of grey clustering analysis in oxidative desizing of indigo denim

以退浆温度、pH、过氧化氢和过硫酸铵用量为影响因子,按正交试验设计方案对靛蓝牛仔织物进行退浆,通过测定织物退浆率、颜色、拉伸强力、摩擦色牢度、毛效和抗弯刚度评价退浆体系作用效果,得出各指标最佳处理工艺条件和各因素作用大小,并在相应的条件下处理织物,对测得的退浆率、K/S值、强力、毛效和抗弯刚度5项指标进行聚类分析,综合评价退浆效果,并得出最佳退浆工艺条件为:退浆温度60℃,pH 7,过氧化氢1g/L,过硫酸铵1g/L。

Taking the desizing temperature, pH value, dosage of hydrogen peroxide and ammonium peroxydisulfate as the influencing factors, the orthogonal experiment of desizing of indigo denim is carried out by measuring the desizing rate, color, tensile strength, rubbing fastness, water absorbent ability and bending stiffness of the fabric and the optimum treatment conditions are obtained. The values of desizing rate,K/S, strength, water absorbent ability and bending stiffness of the treated fabric with the optimum process are analyzed by cluster analysis. The optimum desizing conditions obtained by comprehensive evaluation of desizing performance are as follows: desizing at 60℃ with pH value of 7, hydrogen peroxide of lg/L and ammonium peroxydisulfate of 1 g/L.
