Clothing Increased Banned Azo Test Since August 2012

After a year of pition, the new basic safety technical specification for national textile products will be implemented in August 1st this year. This is what I learned recently from the children's fabric accessories quality control technology exchange meeting. The new standard added a test to prohibit azo 4- amino azobenzene, and the detection of prohibited azo in textiles increased from 23 to 24.

It is reported that in the first half of this year, children's clothing quality testing has also been detected.

National Textiles and clothing

Zhang Yulian, senior engineer of the supervision and Inspection Center (Guangzhou), said that the main problems found in children's clothing spot checks included: banned aromatic amine dyes with carcinogenic activity, banned azo dyes, formaldehyde content exceeding standard, pH value being alkaline, poor color fastness, discoloration or staining; fiber content was not worthy of name; buttons and clothing were not strong enough to sew, and heavy metals could be extracted.

In the long term contact with prohibited human azo dyes, dyes can be absorbed by the skin and spread in the body. These dyes may undergo reductive reaction under the biochemical reaction conditions of normal metabolism of human body, decompose carcinogenic aromatic amines, and alter the DNA structure of human body after activation, causing human diseases or inducing cancer.

Zhang Yulian introduced that more than 300 azo dyes were banned internationally, and they might release 24 kinds of carcinogenic aromatic amines.

The new national standard GB18401-2010 "national textile product basic safety technical specification" has increased this kind of azo detection.

It is worth noting that the new standard also stipulates that the limit value of banned azo is not greater than 20mg/kg, and the old standard does not require it.

Zhang Yulian said that in the first half of this year, the ratio of disqualified azobenzene was slightly higher than that of last year.

Zhang Yulian said that the banned azo exceeded the standard in the pocket cloth and the lining cloth, because these fabrics are cheap, and manufacturers often do not pay much attention to the purchase of dyes.

She said that children's clothing manufacturers should also inspect the purchased fabric accessories, so as to better avoid children's products banned from azo dyestuff projects.

Wang Xueyan, from Huntsman textile dyeing and finishing (China) Co., Ltd. tells me that the price of prohibited azo dyes is ten times lower than that of dyes that are not contained. Great interests drive enterprises to take risks.
