1. Can nylon be labeled as nylon?
Answer: Both nylon and nylon can be labeled. Chemical fibers with abbreviations should use the abbreviations. These two names both belong to the abbreviation of polyamide fibers, in English polyamide or nylon. Nylon is a transliteration of the American word nylon. In some EU countries, nylon specifically refers to polyamide 66. ISO chemical fiber terminology does not use nylon.
2. Can spandex be labeled as "Lycra"?
Answer: No. Lycra is just a brand name for spandex, not a generic name. The full name of spandex is polyurethane elastic fiber elastane or spandex. Lycra is a brand name of elastic fiber produced by DuPont. Because the company holds a dominant market position in the spandex field, Lycra has almost become synonymous with all spandex yarns.
3. Can lyocell be labeled as "Tencel"?
Answer: No. Lyocell fiber, abbreviated as lyocell, is a cellulose fiber obtained by organic solvent spinning technology. Tencel is the English translation of the fiber and is the trademark name of lyocell fiber produced by the British company Acocdis, registered in China under the Chinese name "Tencel".
4. Can mulberry silk be labeled as raw silk?
Answer: No. Mulberry silk cannot be labeled as raw silk. Raw silk is a product of the raw silk spinning process, which refers to the spinning process that processes defective cocoons and waste silk produced during sericulture, silk reeling, and silk weaving into yarn.
5. Can fibers be labeled as "anti-pilling fibers"?
Answer: No. Anti-pilling fiber cannot replace the fiber name; it is only a functional description of the fiber because no specific fiber generic name is indicated.
6. Can viscose be labeled as "artificial silk"?
Answer: No. Viscose in English is viscose or rayon. Rayon means artificial silk, but products sold domestically must be labeled in Chinese. The Chinese generic name is viscose fiber or abbreviated as viscose. Names like artificial cotton or regenerated cotton are not standardized fiber names.
7. Can the care label be labeled as "mercerized cotton"?
Answer: Not standardized. In GB/T 29862-2013 section 5.5, it is stated that terms describing the fiber morphology can be added after the fiber name, for example: cotton (mercerized).
Note: When necessary, relevant parties need to provide proof or verification methods describing the fiber morphology.
8. Can polyester be labeled on the care label?
Answer: Yes. Generally, testing agencies issue results based on the chemical fiber generic name: "polyester fiber". "Polyester" requires relevant proof that the fiber is PET among polyester fibers. Polyester fibers include polyethylene terephthalate fiber (polyester, PET), polytrimethylene terephthalate fiber (PTT), and polybutylene terephthalate fiber (PBT). It is recommended that customers label polyester fiber to reduce risk.
9. The sample seat is made of straw. How should the fiber content be labeled?
Answer: You can directly label the material name, for example, straw; or label it as "plant material."
10. Why does the test report result show other special animal hair?
Answer: Currently, some animal hair fibers have similar morphology, such as fox hair fiber, raccoon dog hair fiber, mink hair fiber, etc., making it difficult to identify the specific species. For special animal hair fibers without mature qualitative identification methods, they can be labeled as "other special animal hair."
11. Can bamboo fiber be labeled on the care label?
Answer: Yes, but corresponding raw material proof and verification are required before issuance. However, many in the market use bamboo pulp fiber to falsely claim it is bamboo fiber. Bamboo fiber is bamboo processed physically and mechanically to form bamboo raw fiber. Bamboo pulp fiber can only produce viscose fiber (bamboo chemically processed into pulp spinning fiber).
The three major domestic fiber name source standards you must know:
GB/T 4146.1-2009 Textiles Chemical Fibers Part 1: Generic Names
GB/T 11951-2018 Textiles Natural Fibers Terminology
GB/T 17685-2016 Down and Feathers
For textile products sold domestically, the fiber content labeling standard GB/T 29862-2013 sources fiber generic names from the above three standards!
