秋冬换季选购衣物时，不少人会被面料标签上的"纯棉""全棉""100%棉"绕得晕头转向，那么这几个词之间有区别么？ 根据国家推荐性标准GB/T 29862-2013《纺织品 纤维含量的标识》中对纺织品纤维含量表示方法的规定：仅有一种纤维组分的产品，在纤维名称的前面或 后面加"100%"，或在纤维名称的前面加"纯"或"全"表示。 所以根据这条规定，"纯棉"、"全棉"和"100%棉"是同样的含义，即表示这件纺织品或者服装只使用了一种纤维即棉纤维。但是有些商家在宣传产品时，为 了强调其棉产品的特性例如亲肤柔软、天然触感、不含其他化纤成分等，会着重声称产品是"全棉"的。 但是有些商家会将棉纤维含量在75%以上的面料就称为"纯棉"，以此突出其以棉为主，但其实这样的做法并不符合规范，容易误导消费者。大家在做选择 的时候，尤其是想购买100%棉产品的时候，最好还是要去查看产品的成分标签，合规的产品会明确表示纤维组成和比例。 为何棉服填充物偏爱聚酯纤维？ 无论是棉服、羽绒服还是棉袄，保暖的核心原理都不是面料或填充物本身发热，而是通过填充物的结构锁住空气。空气是极佳的隔热介质，静止的空气可 以减少人体热量向外界环境散失，达到保暖 ...
