摘要
为了优化三维卷曲中空涤纶/棉非织造保暖材料的制备工艺,以三维卷曲中空涤纶含量、针刺密度、针刺深度为自变量,保温率为响应值,设计三因素三水平响应面实验,并建立回归模型。结果表明:回归模型极度显著且拟合良好,能很好地解释响应值的变化;影响三维卷曲中空涤纶/棉非织造保暖材料保温性能的因素依次为三维卷曲中空涤纶含量比、针刺密度、针刺深度;最优制备工艺为三维卷曲中空涤纶/棉/低熔点纤维比例50∶35∶15,针刺密度为10刺/cm2,针刺深度5 mm。
In order to optimize the preparation process of three-dimensional crimp hollow polyester/cotton nonwovens thermal insulation material,the response surface method box Behnken design was used.The three-dimensional crimp hollow polyester content,needling density and needling depth were taken as independent variables,and the response surface experimet of three factors and three-level was designed with the heat preservation rate as the response value,and the regression model was established.The results show that the regression model is extremely significant and well fitted,which can well explain the change of response value;the factors that affect the thermal insulation performance of three-dimensional crimp hollow polyester/cotton nonwovens are the content ratio of three-dimensional crimp hollow polyester,needling density and needling depth;the optimized scheme is that the ratio of three-dimensional crimp hollow polyester/cotton/low melting point fiber is 50∶35∶15,needling density is 10 stitches/cm2,and the depth of acupuncture is 5 mm.
