Huang Jichang, director of the Yunnan Fiber Inspection Bureau, said that from the investigation, the 'black heart cotton' is not only concentrated in urban and rural junctions and rural markets, but because of the increasing level of manufacturing of 'black heart cotton', in terms of appearance, the average consumer has already It is impossible to judge whether the purchased product is 'black heart cotton', and 'black heart cotton' has gradually entered the urban wholesale market, and some urban retailers also have sales. Most of the purchasers are concentrated in migrant workers, college students and some low-income people.
Professionals remind that the cotton products currently sold on the market are basically sealed and sewn. It is difficult for consumers to distinguish between authenticity and counterfeiting when purchasing. Therefore, when purchasing fiber products, try to use products that can be viewed inside and fully labeled. There are factory names, sites, specifications, grades, fiber components, etc.

The quality qualified fiber is loose, evenly distributed and elastic. If the hand feel is not smooth, no stretch, easy to stick, and the clothes are basically 'black heart cotton'; 'three pull': 'black heart cotton' is composed of industrial waste and waste fiber Therefore, the fiber is short and the strength is low. It is possible to take a bundle of fibers and use both hands to pull and tear. If the fiber is short, it is only about 13 mm. The broken fiber is broken and the strength is low, which is basically ' Black Heart Cotton'; 'Four Beats': 'Black Heart Cotton' products contain high impurity rate, easy to cause itching and red spots on the skin. When you buy, you can force the product to see if there is a lot of dust; 'Wuwen': smelling whether there is any smell, the chemical treatment of 'black heart cotton' by bleaching destroys the cotton fiber skin, so it smells bad.
