基于正交试验和回归分析的羽绒服装样板缩率研究

为揭示影响羽绒服装缩率各影响因素的重要程度及其和缩率之间的定量关系,采用正交试验方法,选择羽绒填充量、绗线间距、含绒量为因素,结合极差分析法探讨各因素对缩率的重要程度,并建立缩率与各影响因素的多元线性回归方程.结果表明,影响羽绒服装样板缩率各因素的主次顺序为:羽绒填充量绗线间距含绒量;对回归方程的显著性和系数显著性探讨表明,回归方程对垂直绗线方向缩率具有显著性影响;回归方程的建立能够有效提高羽绒服装样板制作的准确性,为其他填充类服装制板提供理论参考.

Research on shrinkage of down wear pattern based on orthogonal test and regression analysis

In order to expound the quantitative relationship between the shrinkage of down wear and main influenced factors.The author chooses filling density of down material（A）,distance of sewing threads（B） and down content（C）as three factors for orthogonal testing.And then build a mulitiple linear regression equation based on testing dates.The results showed that,first,the order of priotity for influencing the shrinkage is A＆gt;B＆gt;C,second,the regression equation had a signigicant effect for the shrinkage on the perpendicular direction to sewing threads only.Above results can improve the accuracy of down wear pat-tern making and helpful for pattern making of other filling colthing.
