纺织品产品质量检测中的勾丝性能检测

发布时间:2022-01-20 11:34

  纺织品中纤维和纱线由于勾挂而被拉出织物表面的现象称为勾丝。针织物和变形长丝的机织物在使用过程中,遇到坚硬的物体,极易发生勾丝,并在织物表面形成丝环和(或)紧纱段。当碰到的是锐利物体,且作用力剧烈时,单丝易被勾断,呈毛丝状突出于织物。织物产生勾丝,不仅外观严重恶化,而且影响织物的耐用性。
 

  一、检测标准

  GB/T11047一2008《纺织品织物勾丝性能评定钉锤法》。
 

  二、适用范围

  BENBIAOZHUNGUIDINGLECAIYONGDINGCHUIFACEDINGZHIWUGOUSIXINGNENGDESHIYANFANGFAHEPINGJIAZHIBIAO。

  BENBIAOZHUNSHIYONGYUZHENZHIWUHEJIZHIWUJIQITAYIGOUSIDEZHIWU,TEBIESHIYONGYUHUAXIANZHANGSIJIQIBIANXINGSHA

  ZHIWU。

  本标准不适用于具有网眼结构的织物、非织造布和簇绒织物。
 

  三、术语和定义

  (2)GOUSIZHANGDU:GOUSICONGQIMODUANZHIZHIWUBIAOMIANJIANDEZHANGDU。

  (3)紧纱段(紧条痕):当织物中某段纱线被勾挂形成勾丝,留在织物中的部分则被拉直并明显紧于邻近纱线,从而在勾丝的两端或一侧产生皱纹和条痕。
