通常人们在买了衣服后,根本就没有想到先要清洗一下。其实,贴身穿的新衣需要洗一洗,因为上面可能残留有防皱处理时用的有害化学物品甲醛。我们常常会发现新衣服有一种刺鼻的异味,那就是甲醛,是用于处理棉布易皱缺点的。在高温、高压的条件下,甲醛分子能与棉纤维分子交链结合而产生防皱效果。但用此法处理后的布料如果浸洗不彻底,布料中留有甲醛单体,就会使衣服带有刺鼻的异味。
After people usually bought clothes, they did not think about cleaning first. In fact, wearing a new dress needs to be washed, because there may be residual anti-wrinkle treatment with harmful chemicals formaldehyde. We often find new clothes have a pungent odor, that is, formaldehyde, is used to deal with cotton shortcomings. Under the conditions of high temperature and high pressure, formaldehyde molecules can bond with cotton fiber molecules to produce anti-wrinkle effect. However, if the fabric treated with this method is not thoroughly dipped, the formaldehyde monomer left in the fabric will cause the clothes to have pungent odor.
