　　【化工仪器网政策标准】双组分复合纤维综合了两组分材料的优异性能，得到行业广泛关注和应用。目前开发的商用化双组分复合纤维越来越多，范围越来越广泛，产值也越来越大，但目前未有双组分复合纤维定性定量的标准和相关关键技术，国内外针对混纺纺织品的定量分析标准不适用定量分析双组分复合纤维中各组分质量百分含量。故而，为确保贸易双方的公平公正，确保贸易秩序的稳定，促进纺织新材料新技术的应用，加快我国纺织服装行业的转型升级，制订相关标准法规势在必行。

　　《纺织品双组分复合纤维定量分析方法熔融显微投影法》是一项由全国纺织品标准化技术委员会归口上报，全国纺织品标准化技术委员会基础分会执行，中国纺织工业联合会主管，五邑大学、中山出入境检验检疫局、广东检验检疫技术中心主要起草的推荐性标准，目前正面向社会征求意见。

　　阅读《纺织品双组分复合纤维定量分析方法熔融显微投影法》征求意见稿后可知，本标准是按照GB/T 1.1-2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规定起草的，其内容包括有范围、规范性引用文件、术语和定义、原理、试剂、仪器和设备、试验步骤、计算与结果的表示、试验报告以及资料性附录。

　　标准规定了采用熔融显微投影法测量双组分复合纤维中各组分质量百分含量的方法，该方法的原理是用体视显微镜观测并采集复合纤维横截面图像后，根据其横截面上各组份熔点进行定性，在测定其横截面图像中各组分相应面积或两者间面积比后，结合各组分密度，即可计算其相应的质量百分含量。而该试验的所需要的仪器大致有哈式切片器、刀片、熔点测定仪、数字式金相体视显微镜、显微投影仪、方格描图纸、电子天平等。

　　掌握采样和制样的知识十分重要，如果制样和采样的不正确，有可能会给生产和科研带了不好的后果，故而标准中详细描述了纤维试样制备的具体过程，其大致是取适量代表性纤维样品梳理平直，放入哈式切片器矩形槽中，夹持固定后，用刀片沿着切片器上下面平纤维样品上、下两端，制备出测试用纤维试样，之后分别用3个哈式切片器制备3分纤维试样。

　　本标准与现有定性定量分析标准不重复，其正式出台弥补了显微投影法的不足和局限性，相信在其正式使用后，能有效提高检验效率，降低化学溶解法的检验成本。
