Revealing Clothing Invisible Killer

　　 Recently, the quality inspection departments around the country have checked the clothes for inspection and detected many. clothing Some products of enterprises contain Carcinogen Quality, product quality is not qualified, caught in the "clothing carcinogenic door" embarrassing situation. Searching for the truth of carcinogens and controlling and solving carcinogenic substances have become domestic and international clothing. enterprise Top priority.

In response to this problem, interviewed Meng Lingxiu, deputy director of the national clothing quality supervision and Inspection Center (Tianjin). She made professional analysis of the national standards and residue reasons of carcinogens in textile and clothing.

　　 Carcinogen: the true face of invisible killer

Meng Lingxiu said formaldehyde, pH and decomposable carcinogenic aromatic amine dyes are the three most easily detected carcinogens. They are becoming invisible killer of human body through clothing close to human body. What is the true face of this invisible killer and how many destructive powers are there?

Formaldehyde: formaldehyde gives textiles shrink proof, anti wrinkle, iron free and easy to decontamination functions. But it produces strong stimulation on the respiratory tract and skin of the human body, triggering airway inflammation and dermatitis. In addition, the skin is also an initiator of many allergies. The laws and standards of various countries strictly limit the formaldehyde content of products.

PH value: the surface of human skin is slightly acidic to ensure the balance of permanent bacteria and prevent the invasion of pathogenic bacteria. Therefore, the pH value of textiles is conducive to the protection of human body between slight acid and neutral. In addition, if the textile is in strong acidic or alkaline conditions, it will not only be easy to damage, but also irritate the skin.

Degradable carcinogenic aromatic amine dyes: azo dyes are the most widely used synthetic dyes for textile and clothing in printing and dyeing processes. They are used for dyeing and printing of many natural and synthetic fibers, and also for coloring paints, plastics, rubber and so on. Under special conditions, it can decompose more than 20 kinds of carcinogenic aromatic amines, which can change the DNA structure of human body and induce cancer through activation.

Most of the unsafe clothing is brightly coloured with rich printed patterns on the chest. Carcinogenic aromatic amines exist in these colourful clothing dyestuffs. The dye is colorless and tasteless, and the instrument can not be identified or washed away.

When buying natural fiber clothing such as cotton and linen, consumers should try to choose colors that are close to natural fiber colors (such as cream and light camel), and buy brightly coloured clothes, especially red and purple. Try to choose the clothes with the mandatory national standard for GB18401-2003 textiles.
