Textiles - Identification of fiber content
1 Scope
This Standard specifies the label requirements, labeling principle, expression
method, tolerance and mark compliance determination of fiber content of
textiles, and gives mark examples of fiber content of textiles.
This Standard applies to domestic sales of textile products. The scope of this
Standard does not include the products listed in Appendix A, except as
otherwise provided by the nation.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any
amendments) applies.

GB/T 11951 Textiles - Natural fibers - Generic names and definitions
GB/T 17685 Down and feather
3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Textile products
The products that take natural fiber and chemical fiber as main raw material,
and are made by spinning, weaving, dyeing and other processing or re-stitching,
or recombination, such as yarns, fabrics as well as their finished products.
[GB 18401-2010, Definition 3.1]
3.2 Permanent label
Label that is permanently attached to the product, and maintained legible during
the use of product.
[GB 5296.4-2012, Definition 3.5]
4 Label requirements for fiber content
4.1 Each product shall be attached with fiber content label, indicating the name
and content of each component fiber in the product.
4.2 Each finished product shall be attached with permanent label of fiber
4.3 For products of which the permanent label shall affect product’s use or
permanent label is not suitable (for example, fabrics, wools, gloves, socks, etc.),
it shall use tag or other forms of label.
4.4 Products with permanent label are not suitable for sales in whole box or
whole bag. If fiber content of each product is same, it shall provide fiber content
label with sales unit as unit.
4.5 When a packaged product is for sale, if fiber content on textile product
cannot be seen clearly (except products that comply with provisions in 4.4), it
shall indicate the fiber content on product package or in product description.
4.6 For set product that consists of two or more products, of which fiber content
is different; OR set product of which fiber content is same but each product is
for sale separately, it shall have independent fiber content label on each product.
4.7 For set product of which fiber content is same and is delivered to final
consumer as a set, the information of fiber content shall be only marked on one
4.8 If the product is not delivered to final consumer, the fiber content label shall
be alternated by business document.
4.9 The material of permanent fiber content label shall be no stimulation to
human body. It shall be attached on appropriate position to ensure that
information on the label is not covered or hidden.
4.10 Writing on the fiber content label shall be clear, eye-catching; the text shall
use standard Chinese characters prescribed by the nation. It shall also use text
in other languages; however, identification in Chinese shall prevail.
4.11 Fiber content shall be marked with other content of instructions for use on
a same label. If there are different forms of fiber content label on a textile
product, it shall maintain the consistency of marked contents.
Appendix A
Textile products not included in the scope of this Standard
The following products which contain textile fibers are not included in the scope
of this Standard. Textile products are only parts or accessories of the product.
The products of which it is unnecessary to indicate the textile fiber contents are
as follows. For example,
- Disposable products;
- Filler and wrapper used for upholstered furniture like chairs, sofas, and
- Shoes and insoles;
- Decorative painting and decorative hanging cloth;
- Jewelry, crafts and other small pieces of decorations;
- Umbrellas and parasols;
- Bags, back bags, packaging cloth and rope;
- Pants suspenders, armlets and garters;
- Diaper liners;
- Crib protector and strollers;
- Toys;
- Bandages, surgical gowns and other medical textile products;
- Pet supplies;
- Cleaning cloth;
- Wall covering and screen;
- Banners;
- Artificial flowers;
- Industrial textile products.
Appendix B
Marking examples of other fibers or materials
B.1 For composite fiber that contains two or more polymer components, it shall
use the following method to indicate the fiber name. use the name specified in
GB/T 4146.1; list the name of each component + composite fiber; separate
components by “/”. Refer to Example 1 and Example 2.
Example 1.
Example 2.
B.2 For modified fiber of which it adds components to change the original
chemical properties, it shall use the following method to indicate the fiber
name. name of added component + modification + name of original chemical
fiber. Refer to Example 3 and Example 4.
Example 3.
Example 4.
B.3 Because molecular chain has fiber that is composed of 50% ~85% (mass)
linear macromolecules of acrylonitrile, it shall be marked as “modacrylic”.
B.4 For fiber that is composed of two or multiple linear macromolecules in a
variety of different chemical properties (the mass shall not exceed 85%),
contains at least 85% ester functional group, and of which 50% can be quickly
restored to its original length after repeatedly stretching, it shall be marked as
“elastomultiester or relasterell-p”.
B.5 For other chemical fibers of which the names are not unified, they shall be
marked as “new type of ×× fibers”. If necessary, related parties shall prove proof
or identification method for “new type of ×× fibers”.
B.6 For special animal hair fiber that cannot be identified by proven methods, it
shall be marked as “other special animal hair”.
100% Polypropylene / polyester composite fiber
60% Cotton
40% Polyester / nylon composite fiber
100% Protein modified polyvinyl alcohol fiber
70% Wool
30% Protein modified polyacrylonitrile fiber
B.7 For other material on textile products, if necessary, the proposed label
names shall be.
- Paper type yarn. if it were cellulosic material, it shall be marked as
“cellulosic material”;
- Plant material. names that can be directly marked, such as corn bran, straw;
or marked as. “plant material”;
- Bird feather. names that can be directly marked, such as peacock feather,
ostrich feather; or marked as “bird feather”;
- Film. shall be marked as “except film”; or shall be qualitatively marked, for
example, “except polyethylene film”;
- Metallic yarn, glitter line. if it cannot be determined as metallic-membrane
plating, it shall be marked according to its material, for example, “bright yarn.
polyester film fiber”;
- Leathers, furs. marked according to names specified in relevant standards.
