响应面法优化BTCA-CA棉织物抗皱整理工艺（英文）
|
摘要
采用1,2,3,4-丁烷四羧酸(BTCA)与柠檬酸(CA)复配对棉织物进行抗皱整理,基于响应面法(RSM)建立了该工艺的二次多项式数学模型。利用模型对整理工艺进行分析和优化,并通过实验数据对模型的有效性进行验证。模型的因变量为折皱回复角(WRA)和断裂强力,自变量为BTCA用量,CA用量,次亚磷酸钠(SHP)用量,培烘温度和培烘时间。模型的方差分析(ANOVA)表明,培烘时间对回复角影响最大,BTCA用量和CA用量、培烘温度、SHP用量的影响程度依次降低;对于断裂强力来说,培烘时间对断裂强力影响程度最大,培烘温度、SHP用量、CA用量、BTCA用量的影响程度依次降低。优化工艺为:BTCA 50g/L,CA 45g/L,SHP 33g/L,162℃培烘63s。整理织物的折皱回复角为260°,断裂强力保留率为72%。
A two-dimensional numerical model was developed to investigate and optimize the durable press(DP)finishing process of cotton fabric with a combination of 1,2,3,4-butanetetracarboxylic acid(BTCA)and citric acid(CA).The numerical model was validated by experimental data.Response surface methodology(RSM)was used to establish mathematical models of the wrinkle recovery angle(WRA)and the breaking strength as the function of the operating parameters involving BTCA concentration,CA concentration,sodium hypophosphite(SHP)concentration,curing temperature,and curing time.Analysis of variance(ANOVA)for the models revealed that the curing time was the most significant factors affecting WRA,followed by the concentration of BTCA and CA,the curing temperature and the concentration of SHP.As to the breaking strength,the curing time was the most significant variable,followed by the curing temperature,the concentration of SHP,the concentration of CA and the concentration of BTCA.The optimal process is as follows:BTCA 50 g/L,CA 45 g/L,SHP 33 g/L,curing at 162℃for 63 s,and WRA of the finished cotton fabric in this condition is 260° and breaking strength retention is 72%.
