Generic Names; --- Part 2. Terms of Products; --- Part 3. Terms of Inspection. This Part belongs to Part 2 of GB/T 4146. This Part was drafted as per the rules specified in GB/T 1.1-2009. This Part replaced the content of 1.3 “general name” in GB/T 4146-1984 Textile Terms and Terminology (Parts of Chemical Fibers); compared with 1.3 in GB/T 4146-1984, this Standard has the major technical changes as follows. --- Make 1.3 of the original standard into independent Part 2; the number of terms is increased from 39 to 93; ---According to the characteristics of chemical fiber products, give the product terminology of chemical fiber in six categories; --- Increase the terminology of three types of fibers, namely, bio-based, intelligent and recycling; ---Supplement both the functional and high-performance fiber terms; delete the relevant terms of textured yarn. This Part was proposed by China National Textile and Apparel Council. This Part shall be under the jurisdiction of National Technical Committee for Standardization of Textile Products (SAC/TC 209).

Textiles – Man-Made Fibers – Part 2. Terms of Products 1 Scope This Part of GB/T 4146 defines various terms and definitions of the chemical fiber products used for textiles or other objectives. This Part is applicable to the production, use, commerce, scientific research, teaching and other fields of the chemical fibers. 2 Product Classification 2.1 Man-made fibers; chemical fibers Man-made fibers other than natural fibers. NOTE. The chemical fibers can be divided into regenerated fibers, synthetic fibers, and inorganic fibers. 2.2 Regenerated fibers The chemical fibers produced by spinning process using natural products (cellulose, protein, etc.) as the raw materials. 2.3 Synthetic fibers The chemical fibers made of polymer synthesized from a chemical raw material such as organic monomer, etc. 2.4 Inorganic fibers The fibers made from minerals and the like. 2.5 Regenerated cellulose fibers The regenerated fibers made from natural cellulose as a raw material through a spinning process. 2.6 Regenerated protein fibers The regenerated fibers made from natural protein as the raw material through a length and thickness as the cotton fiber. 3.15 Wool type fibers The chemical fiber with length about 70mm~150mm; linear density of 3.33dtex above; similar length and thickness as the natural wool. 3.16 Mid fibers The fiber with length about 51mm~76mm; linear density of 2.20dtex~3.33dtex; between the cotton fiber and wool fiber. 3.17 Profiled fibers The fiber having a particular cross-sectional shape spun from a certain geometric (noncircular) orifice. 3.18 Hollow fibers The fiber in tubular shape, cavity, and penetrates the fiber axial direction. 3.19 Hollow fibers membrane The selective permeable hollow fiber with micropores in the fiber wall; the microporous size is from nanometer to micrometer. 3.20 Superfine fibers; microfibers The fiber with monofilament linear density less than or equal to 0.33dtex. 3.21 Nanofibers The fiber with an average diameter less than 100nm. 3.22 Bright fibers; lustrous fibers The fiber produced by a matting process without chemical or physical means during the spinning process. 3.23 Dull fibers The fiber produced by a matting process with chemical or physical means during the spinning process. NOTE. Titanium dioxide is usually used as a matting agent; it can be divided into micro-dull fiber, semi-dull fiber and full-dull fiber according to the adding amount of titanium dioxide. 3.24 Three-dimensional crimp fibers 4.4 Binder fibers The fiber having a lower melting point and softening point; having an adhesive property beyond the melting point. 4.5 Flame retardant fibers The fiber, after leaving the flame, can quickly extinguish the flame-burning and flam-less burning. 4.6 Luminescent fibers; luminous fibers The fiber that emits visible light when exposed to radiation. 4.7 Heat accumulating fibers The fiber that can converts sunlight or infrared light into heat and store it into the fiber. 4.8 Medical fibers The special medical fiber used for producing the human body substitute materials and medical and heath materials. 4.9 Radiation resistant fibers The fiber with outstanding radiation resistance against the rays and neutron flux. 4.10 Optical fibers The concentric sheath-core composite fiber or coated fiber that can conduct light. 4.11 Ultraviolet resistant fibers The fibers that can block and absorb the ultraviolet light. 4.12 Structural coloration fibers The fiber that produces color by action of light scattering or interference by a microstructure. 4.13 Antistatic fibers The fiber that is difficult to accumulate static charges and prevent static electricity or eliminate static electricity; it is also known as antistatic fiber. 4.14 Electro conductive fibers The fiber made of conductive material or sub-conductive material totally used or partially used the metal or conductive organic substance. 6 Bio-Based Fibers 6.1 Regenerated bio-based fibers The fiber made by spinning a biomass as a raw material. 6.2 Synthetic bio-based fibers The fiber that produces small molecule by fermentation with using biomass as a raw material; then produces polymer by polymerization then by spinning. 6.3 Marine bio-based fibers The fiber made by spinning marine organism or marine organism extracts. 7 Intelligent Fibers 7.1 Chameleon fibers The fiber whose color changes reversibly with changes in external light conditions. 7.2 Polychromatic fibers The fiber whose color changes reversible with temperature changes. 7.3 Shape memory fibers The fiber capable of returning to the original shape given to the outside under certain conditions. 7.4 Thermoregulating fibers The fiber that achieves a temperature adjustment function within a certain period of time according to the change in ambient temperature. 7.5 Self-repairing fibers The fiber, after a certain degree of damage, can regain the properties by self-diagnosis and self-healing functions. 8 Recycled Fibers 8.1 Physical recycled fibers The fiber made by melting the recycled materials, or by other physical methods. ......
