After the reform and opening up, China attaches great importance to the standardization of textiles and clothing signs, and the use, supervision and management of clothing signs are also constantly strengthened and improved. However, it should be admitted that the size of China's clothing market is not commensurate with its standardization and maturity. In China's large clothing market, even in addition to those fake and shoddy and shoddy goods, in the regular market of many brand clothing washing marks, the fiber raw materials still have such and such randomness, not able to accurately reflect the fiber content and maintenance methods are not uncommon.
In January 1984, China participated in the third Multifiber Agreement and became a member of the GATS Committee on Textile Products. On the one hand, China's textile and garment exports grew from $6.6 billion in 1984 to $17.8 billion in 1991; on the other hand, China is in a good position in the textile trade negotiations with western countries. Through negotiations, western countries cancelled some restrictions on China's textile exports, and better resolved the dispute over textile trade between China and the United States through the Multiple Fiber Agreement.
In 1998, China's quality supervision department promulgated and implemented the GB5296.4-1998 "Instructions for Consumer Goods and Use textiles and Clothing" mandatory standards.
See the Instructions for Use of Textiles and Clothing (GB5296.4-1998):

7.3.2 Label position of clothing products 7.3.2.1 The number and type marks or specifications of clothing products can generally be sewn in the back collar. Coats, suits and so on can also be sewn in the top or bottom of the front bag; pants and skirts can be sewn in the back of the waist.7.3.2.2 The labels of raw materials, composition and content and washing methods of clothing products can generally be sewn in the middle and lower part of the left swing seam. Skirt, pants products can be sewn in the waist under the seam or the left side of the skirt, the side of the seam.7.3.3 The labels of scarves and shawl products can be sewn at the corners.7.3.4 The label of the tie can be sewn at the wide or narrow head joints on the back.7.3.5 Labels on home textiles (tablecloth, sheets, bath towels, bedcovers, blankets, etc.) can be sewn at the corners.
7.4 Location of instructions on cloth, wool, sewing thread, socks and other textile products 7.4.1 Instructions for the use of cloth can be placed in one of the following ways: a) attach labels or tags to the end of the fabric roll; b) brush or weave on the weaving edge.7.4.2 Instructions for the use of wool and sewing thread can be marked on the tag or on the hoop of wire coil, wire ball and wire harness.7.4.3 The instructions for using socks can be marked on the label at the socks.
7.4.4 Labels of other textile products can be placed in place 7.5 The position of labels on special process products can be set as required.
The standard further emphasizes that the labels should be permanently fixed to the textile, and that the symbols are not hidden, allowing consumers to easily find and identify them. Because the clothing will be changed hands after the factory, if it is damaged in the circulation process, it will be severely punished by the relevant departments. In other words, clothing labels must be permanent throughout the life cycle, and they should be easy to understand. So, even if the manufacturer not only continues to put the labels on the collar, but will sew them so strong that they are easy to break them if the skills is not good.
At the same time, from the perspective of clothing production and circulation, the inside of the collar is the best optional position. The collar is the most prominent part of the packaged garment. Most clothes have the front collar is lower than the back collar, and the inside of the packaged finished collar is usually revealed, and can not be seen when worn. Whether stacked or hung, you can find the LOGO and size without unwrapping the clothes. Booking in this conspicuous part, also convenient internal staff and sales staff to distribute goods take goods.
The label is very strong because the market businesses choose to make the label materials are basically polyester material, polyester price is cheap, not easy to wash off. But this material is not close to the skin, very hard, so it will be very uncomfortable. At present, many garment factories stand from the point of view of customers, but also made some improvements. For example, use a cotton label, choose hot transfer print hot label, or sew in the side of the clothes.
But the mainstream is still in the middle of the back neck. In fact, it is also very simple to deal with the trademark, do not directly tear off or reduce the stitches, so that it is easy to destroy the clothes. Remove the label at the root of the suture and wash the rest a few times!
