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.

3.39 Carbon fiber precursor

The special fiber that meets the requirements for carbon fiber production, also known as carbon fiber precursor.

4.1 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.

5.1 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

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.

8.1 Physical recycled fibers

The fiber made by melting the recycled materials, or by other physical methods. […]
