What's the name of underwear with triangle marks?

As far as texture is concerned, most materials used to make labels are paper, plastic and metal. In addition, a new label made of holographic anti-counterfeiting material has appeared. Judging from its shape, it is more diverse: there are special shapes such as long strip, folded shape, circle, triangle and bag, which are really colorful and dazzling.

The design and printing of clothing tags are often exquisite and have a wide range of connotations. Although the tag of each clothing enterprise has its own characteristics, most of them are printed with the name, address, telephone number, zip code, logo and so on. Some enterprises are also printed with the nature of the company (such as Sino-foreign joint ventures, sole proprietorships, etc.). ); Other clothing manufacturers simply regard the small tag as a miniature "advertisement" and print photos of supermodels and beautiful women wearing their products on it, giving people a more intuitive feeling and making consumers have a deeper impression on their products, which has played a very good role in publicity and promotion; Some manufacturers, in order to thank consumers for buying their own products, often have to print the words of thanks and wishes on the tag, giving people a sense of intimacy; Some tags are more like "product instruction manual", because they are printed with not only what kind of fabric and performance the product needs, but also the water temperature, washing method, cleaning agent and how to maintain it, which shows that the manufacturer is very responsible to consumers. In addition, with the increasing prosperity of the clothing market, the competition is bound to be more intense. Some famous brand manufacturers have used various holographic anti-counterfeiting labels and bar codes to protect their products from counterfeit and shoddy products. This not only protects the interests of enterprises themselves, but also protects the rights and interests of consumers.
