some clothes are listed without several kinds of signs because the manufacturer or seller of the product has violated the law and failed to mark the relevant information according to the law. According to the Textile Labeling Law, textiles must be marked with information such as "name and proportion of fiber components", "washing, dry cleaning and ironing methods" and "safe use of drugs" in a prominent position. In addition, in order to ensure consumers' right to know and choose, relevant information including trade name, manufacturer, applicable gender, size, color, price, etc. should also be marked on the clothes' listing or tag. Therefore, in fact, several logos are necessary, and these logos are an important basis for consumers to distinguish the quality and use of products. If some clothes are not marked with these signs, it is because the manufacturer or seller of the product has violated the law and failed to mark the relevant information according to the law. Consumers should pay attention to whether these signs are complete when purchasing, and ask the seller for relevant information if necessary to protect their rights and interests.
