摘　　要：针对涤棉混纺织物"烛芯效应"而引起的阻燃整理难度大的问题,采用复合新型阻燃剂复配技术对涤棉混纺织物进行阻燃处理。通过正交试验的方法综合分析了混纺比、织物密度、织物组织结构等影响因素与涤棉织物阻燃性能之间的关联性。研究结果表明,经复配阻燃处理后的涤棉混纺织物的垂直燃烧损毁长度在40～47mm范围内,均<50mm,极限氧指数均>27.5,达到难燃织物的标准;随着织物中涤纶含量的增加,阻燃性能先增大后减小,涤纶含量为35%时阻燃效果最好;阻燃性能与织物密度正相关,而织物组织结构对阻燃影响并不显著。In the light of the problem that it＇s difficult to apply flame retardant finish to cotton-polyes- ter blended fabric as a result of wick effect, the authors adopt a new type of flame retardant to finish the fabric. Additionally, the compositions of fire retardant will coordinate to achieve flame retardancy. Based on this, the authors utilize orthogonal experiment to analyze the way in which how blending ratio, fabric density and fabric structure affect the flame retardant performance of cotton-polyester blended fabric. It turns out that the vertical burning damage length is from 40 to 47 mm, which is less than 50 mm, and the limiting oxygen index is greater than 27. 5, which reaches the requirements for flame retardancy. The flame retardant performance of cotton-polyester blended fabric is closely related to the contents of the fire retardant and the way to apply fire retardant finish. It also proves that the flame retardant performance of cotton-polyester blended fabric increases and then decreases when the contents increase, the performance is positively correlated to the density of fabric, while the fabric structure does not significantly connect with it.
