盐水洗新内衣有用吗?

许多人穿新买的内衣,穿前习惯用盐水洗涤,这有什么科学道理吗?

大多数消费者喜爱穿纯棉或真丝类制成的内衣,因为穿着舒适。但是无论何种原料制成的衣物面料,均是经过染色和其他方法整理加工的,白色的也多经过增白处理,因此衣物表面难免有染料和化学整理剂的残留物质。我们平常提到的衣服上的游离甲醛是纺织品在后整理过程中,为防止面料起皱用的整理剂在高温加工过程中产生的。纯棉、涤棉类纺织品的整理剂中有一类就是如此。另外,在染棉制品的染料中有18种偶氮染料,已被证明对人体有害,在欧洲被明令禁止使用,但在我国一些纺织厂依然在使用。

篮球世界杯下注我国对纺织品、服装加工中所含有的各种有害物质是有标准的。一般大型企业生产的产品均能够达到这一标准,但纺织业小企业众多,达不到标准的产品也不少。为了安全起见,建议大家在穿新内衣前最好先洗涤一下。 

那么一定要用盐水洗涤吗?不一定。盐水的主要成分是氯化钠,染料和整理。
