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 Products1 ScopeThis 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 Classification2.1 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 spinning process.3 General3.1 Filament Single or multiple yarns with long continuous length. The length is generally recorded in km. 3.2 Staple fibers Segmented fiber of chemical fiber. 3.3 Industry filament The chemical fiber filament with high physical and mechanical properties for industrial applications. 3.4 Monofilament Continuous filament of one fiber. 3.8 Full drawn yarn; FDY The full crystallized, oriented chemical fiber filament obtained by a one-step spinning and stretching process. 3.9 Textured fibers The fiber has (or potentially has) appearance characteristics such as curl, spiral, loop, etc.; and exhibiting bulkiness and stretching properties. 3.10 Draw textured yarn; DTY The deformed fiber, which is also called elastic yarn, is produced by all or part of the stretching stage of the chemical fiber filament and the deformation process are performed on the same machine. There are low-elastic yarns, medium-elastic yarns and high-elastic yarns by different production processes. 3.11 Bulked continuous filament; BCF The fluffy filaments made by spinning, drawing, hot air deformation. 3.37 Top Strip-shaped fiber aggregate made of chemical fiber raw material. 3.38 Tire cord The strong strand used for tire-cord fabric warp. 3.39 Carbon fiber precursor The special fiber that meets the requirements for carbon fiber production, also known as carbon fiber precursor.4 Functional Fibers4.1 Elastic fibers The fiber with high elongation and high resilience. 4.2 High shrinkage fibers The fiber with high shrinkage rate after the heat treatment. 4.3 Low shrinkage fibers The fiber with low shrinkage rate after the heat treatment. 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. 4.15 Anti-microbial fibers The fiber that kills or inhibits the growth of microorganisms; including antibacterial, antifungal fibers, etc. 4.16 Stanch fibers The porous soft fiber that has excellent adhesion and coagulation; and is non-toxic and absorbable. 4.17 Absorbable fibers The fiber implanted into the human or animal body; it can degrade itself and be completely absorbed by the implanted body tissue within a certain period of time. 4.18 Micro-organism decomposable fibers The fiber that is completely decomposed by microbial action in an environment such as soil and seawater. 4.19 Reactive fibers The fiber containing chemically reactive group in a main chain or a side chain of a macromolecule. 4.22 Hydroscopic fibers The fiber that can absorb a large amount of vaporous water from its surroundings. 4.23 Water absorbing fibers The fiber with high water absorption capacity and capable of absorbing large amount of liquid water. 4.24 Anti-soil fibers The fiber with the capability of resisting stain or stain releasing. 4.25 Water soluble fibers The fiber that can dissolve in water or slowly hydrolyzes into water to be water-soluble molecules or compounds.5 High Performance Fibers5.1 High strength and modulus fibers The fiber with high tensile strength and modulus. Generally, the tensile strength is greater than 2GPa, tensile modulus is greater than 100GPa. 5.2 High temperature resistant fibers The fiber that can substantially maintain the original physical and mechanical properties of the fiber during a long period of high temperature (such as above 200°C).6 Bio-Based Fibers6.1 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.7 Intelligent Fibers7.1 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. 7.4 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 Fibers8.1 Physical recycled fibers The fiber made by melting the recycled materials, or by other physical methods. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
