Recently, there has been a saying circulating on the Internet that it is better not to buy black underwear. This claim is based on the idea that black underwear may increase the risk of cancer. However, upon in-depth analysis, we can see that this claim lacks scientific basis.
First of all, we need to understand the safety of black dye. Currently, the textile industry mainly uses chemically synthesized dyes, including black dyes. These dyes are not inherently toxic. It is important to note that although there are some azo dyes that may be harmful to humans, they have been banned in most countries. China's national standard GB18401-2010 "National Basic Safety Technical Specifications for Textile Products" clearly stipulates the prohibition of decomposable carcinogenic aromatic amine dyes, and GB19601-2013 "Limits and Determination of 23 Harmful Aromatic Amines in Dye Products" also regulates the development and production of dye products from the source. Therefore, as long as it is a textile and garment product of acceptable quality, it is safe and harmless regardless of color.
Secondly, we need to pay attention to the color fastness of textile and garment products. Some consumers have reported that the color of black textile and garment products has deteriorated severely, which may be due to the fact that the color fastness of the products is not up to standard. The national standard GB18401-2010 specifies the color fastness levels in five scenarios, including color fastness to water, acid perspiration, alkali perspiration, dry rubbing and saliva. Consumers should choose products that meet the requirements of Class B or Class A when purchasing, especially Class A products for infant textile products, so as to avoid potential safety hazards and embarrassment caused by substandard color fastness.
In addition, the statement that "poor-quality fabrics are often dyed black to hide imperfections" does not correspond to the production reality of the modern textile industry. The modern textile industry has achieved large-scale automation and intelligent production, and the level of control over fabric quality is very high. The structure and color of the fabric are planned at the design stage, and the fabric is not dyed black due to weaving defects.
Therefore, there is no scientific basis for the statement that "it is better not to buy black underwear". When buying textile and garment products, consumers should buy products with quality assurance from formal channels, check whether the identification and tags of the products are complete, and pay attention to the dyeing safety and color fastness level of the products. For textile and garment products that meet the best technical specifications, whether it is black or other colors, you can choose with confidence. When shopping for new clothing, it is recommended to wash it properly to remove any floating colors that may be present and feel more comfortable to use.
