FangZhiPin Xian明1 Honliong de BiaOZhi《纺织品纤维含t的标识》(万刀T 01053一1998)(爪荡￡幼郎.加匆刁以勿nof踢。。几饱瓜)纤维种类及其含量是纺织品品质标志的重要内容之一。根据纺织制品形式和结构，提出了标注纤维含t的具体要求，解决了不同产品标识的统一问题，如带里料的产品应对里和面分别标注;带填充物的产品应把填充物和套分别标注;二种以上的不同织物拼接或镶嵌的产品应分别标注不同织物;只起装饰作用而不作为产品主体的可以不标。规定统一采用国家标准规定的纤维名称，避免了任意标注商品名称、外来语名称等造成的纤维名称混乱问题;规定了以成品中某种纤维的量占纤维总量的百分数表示，而不以生产实际的投料比例标注，解决了纤维含t概念(即基数不清)的问题。明确规定了各种纺织品的纤维含量允差，既与原有的纺织品标准衔接，又明确了各种单一纤维纯纺、二组分或多组分纤维混纺或交织产品的明示含t值与实际值可允许的差值，使标准具有可操作性，解决了含t偏差判定的根本问题，使市场抽查有据可依。对统一纤维成分及其含量的标识起到了积极的指导作用，对保护消费者的利益，维护生产者的合法权益有着重要意义。(郑宇英)
