Why is the same big difference between cotton underwear?
Because in most cases, manufacturers do not mark the origin of cotton, and even if the origin of cotton is marked, they cannot describe the processing technology of cotton fibers in a few words. Therefore, except for extremely rare cotton, most manufacturers are uniformly labelled as "cotton", and at the same time, the percentage of cotton fibers in the blend will be indicated in the front.
This creates an illusion for consumers: only the percentage of cotton differs among products, and there is no difference in cotton itself. And this illusion is obviously wrong. Different producing areas mean different sunshine hours and air humidity. Different processing techniques also often determine the quality of cotton fabrics.
Although manufacturers will not list these details on the tag, in general, the price, the letter is big, the probability of error will be very small.
