Anti UV Polyester Flame Retardant Yarn is a functional polyester yarn that combines UV resistance and flame retardancy. Its characteristics can be comprehensively reflected from the dimensions of core function, physical properties, and application adaptability
1、 Core functional characteristics
Excellent flame retardant performance
It has self extinguishing properties and can quickly suppress the spread of combustion when exposed to open flames. After leaving the fire source, it can extinguish itself in a short period of time without continuous smoldering or melting dripping, effectively reducing fire hazards.
Compliant with relevant flame retardant standards (such as GB 8965.1-2020 "Protective Clothing Part 1: Flame Retardant Clothing", EN 11611, etc.), with low smoke density and low release of toxic and harmful gases during combustion, ensuring personal safety during use.
Reliable UV resistance performance
Special anti UV additives are added to the yarn or modified polyester raw materials are used, which can effectively block UV rays in the UVA (320-400nm) and UVB (280-320nm) bands, with a UV protection factor (UPF) of up to 50+, meeting high-level UV protection requirements.
The anti UV performance has good durability, and after multiple washes or sun exposure, it can still maintain a stable protective effect without significant attenuation.
2、 Basic Physical and Chemical Properties
Inherent advantages of polyester substrate
High strength and good wear resistance, with a breaking strength of up to 3-5 cN/dtex, capable of withstanding large tensile and frictional loads, suitable for weaving high-strength fabrics.
Excellent dimensional stability, low thermal shrinkage rate (≤ 3% under normal conditions), the fabric is not easily deformed or wrinkled due to temperature changes, and has good wrinkle resistance and stiffness.
Strong chemical corrosion resistance, good tolerance to acids, bases (weak bases), organic solvents, etc., and not easily degraded or degraded.
Functional compatibility and stability
The anti UV and flame retardant functions do not interfere with each other, and the two modification processes will not cause performance cancellation, which can maintain a high level of protection effect at the same time.
Good weather resistance, the mechanical properties and functional characteristics of the yarn are not easily affected by the environment in complex environments such as outdoor exposure and high humidity, and have a long service life.
3、 Processing and application adaptation characteristics
Good spinnability and weaving performance
The yarn has uniform and less fuzz, and can be adapted to various spinning processes such as ring spinning and air flow spinning. It can also smoothly carry out various weaving processes such as machine weaving, knitting, and non-woven fabrics, and is not prone to problems such as breakage and equipment blockage.
It can be blended or interwoven with other fibers such as cotton, spandex, aramid, etc. to achieve functional complementarity (such as blending with spandex to enhance elasticity and blending with aramid to enhance high temperature resistance).
Wide range of application adaptation scenarios
In the field of outdoor protection, it can be used to make outdoor work clothes, mountaineering clothes, sunshade tarpaulins, etc., which not only prevent ultraviolet radiation but also avoid the risk of outdoor open flames (such as camping campfires).
In the field of industrial protection: flame retardant protective clothing suitable for industries such as metallurgy, power, and petrochemicals, while also resisting ultraviolet radiation during outdoor operations.
In the field of home textiles and decoration, it can produce outdoor curtains, tents, car seat covers, etc., with both flame retardant safety protection and UV aging protection.
4、 Environmental and safety features
The flame retardants and anti UV additives used are mostly environmentally friendly formulas that comply with environmental standards such as RoHS and REACH, and do not release harmful substances such as heavy metals and formaldehyde.
The finished yarn has no irritating odor and no risk of sensitization when in contact with the skin. It can be safely used for close fitting or protective fabrics.
