On February 27, an entry "Why don't people like to buy black underwear" appeared on Sina Weibo's hot search.
According to a report, some netizens recently mentioned the problem of poor quality of black clothes, mainly involving the quality of fabrics and dyeing.
Here is an explanation and explanation of this issue:
On the quality of the fabric and the dyeing issues:
The quality of the fabric is usually not noticeably different depending on the color of the garment. The modern textile industry has strict quality control over fabrics, and each link has quality inspection and monitoring, and the defect rate is greatly reduced.
Even if the fabric is dyed black, there will still be inherent quality problems, such as fiber damage, loss of elasticity, etc., which cannot be concealed.
It is indeed possible to dye poor-quality fabrics black to hide imperfections, but as long as it does not compromise on safety, this practice is not a major problem.
On the issue of fading black clothing:
Colour loss is not limited to black clothing, but can also occur with other colours.
Colour fastness is key, as it directly affects the severity of colour loss of clothing. Consumers should pay attention to the color fastness grade of the product when purchasing and choose qualified products.
About Black Dye Safety:
Most dyes are water-soluble and do not enter the body**. Even if it enters the body, the amount is very limited and does not cause health effects.
Azo dyes are common dyes, and synthetic dyes have the advantages of bright color and washability, and will not cause safety problems because they are black.
At present, azo dyes used in regular products are non-carcinogenic, and the national standards have relevant regulations and restrictions on the use of dyes.
Recommendations:
Choose clothing with acceptable colour fastness to avoid staining problems.
For sensitive people and children, it is best to choose light-colored underwear to reduce the amount of chemicals used.
To sum up, black clothing does not necessarily have quality problems or safety hazards, consumers should pay attention to the color fastness level of the product when purchasing, and choose qualified products to ensure safety in use.
