我国首个口罩用熔喷布团体标准发布,按过滤效率产品分6级
p style=" text-align: justify text-indent: 2em " 4月23日,江苏省纺织工业协会正式发布团体标准《口罩用聚丙烯熔喷非织造布》(T/JSFZXH001-2020),并于4月26日正式实施。 span style=" text-indent: 2em " 该标准是全国首次发布口罩用熔喷布团体标准,主要适用于卫生防护用口罩熔喷布,由团体成员按照约定采用,并供社会自愿采用。 /span /p p style=" text-align: center text-indent: 0em " span style=" text-indent: 2em " img style=" max-width: 100% max-height: 100% width:

/span /p p style=" text-align: justify text-indent: 2em " 熔喷布具有孔径小、孔隙率高、过滤效率高等特点,作为口罩生产的核心材料,当前需求远远大于供给。近期相关企业转产熔喷布,但对所用原料、设备、生产工艺等不够了解,生产的熔喷布过滤效率不高,质量不能满足口罩生产的需要。 /p p style=" text-align: justify text-indent: 2em " 目前,我国现有2项熔喷布相关行业标准,分别是《纺粘/熔喷/纺粘(SMS)法非织造布》(FZ/T 64034-2014)和《熔喷法非织造布》(FZ/T 64078-2019)。前者适用于以丙纶为主要原料,以热轧粘合方式加固的SMS产品;后者适用于以熔喷法生产的非织造布,最终用途不限于口罩,标准仅对幅宽、单位面积质量等提出要求,过滤效率、透气率等关键指标的标准值规定由供需合同约定。目前,企业组织熔喷布生产主要依据企业标准,但相关指标规定也参差不齐。 /p p style=" text-align: justify text-indent: 2em " 此次发布的《口罩用聚丙烯熔喷非织造布》团体标准围绕口罩用聚丙烯熔喷非织造布,规定了原料要求、产品分级、基本技术要求、专项技术要求、检验判定方法,并对产品标识提出了明确要求。团体标准的主要技术指标包括颗粒物过滤效率、细菌过滤效率、断裂强力、单位面积质量偏差率以及外观质量要求。该标准规定了如下内容:一是根据产品过滤效率水平对产品给出了分级,分为KN 30、KN 60、KN 80、KN 90、KN 95、KN 100共 6个等级。二是对使用的原料作出规定,应符合《塑料 聚丙烯(PP)熔喷专用料》(GB/T 30923-2014)要求,限制了有毒有害物质的使用。三是针对不同过滤效率水平所对应的颗粒物过滤效率和细菌过滤效率提出具体要求,以满足不同类别口罩对熔喷布的要求。 /p p style=" text-align: justify text-indent: 2em " strong span
