Total Brgiht Polyester Flame Retardant Yarn is a type of halogen based flame retardant polyester yarn, which refers to functional modified yarn made by adding bromine based flame retardants during the polyester polymerization or spinning stage. The bromine based flame retardant components are either integrated into the fiber molecular structure or evenly dispersed inside the fiber to achieve flame retardant effect. It is commonly used in industrial protection, home textile decoration and other scenarios that require fire prevention. Its core characteristics are as follows:
Outstanding and stable flame retardant effect: When exposed to fire, bromine based flame retardants will decompose to produce free radical scavengers, interrupting the combustion chain reaction, while assisting in the formation of a carbonized layer on the fiber surface, isolating oxygen and heat transfer, achieving self extinguishing upon ignition, and reducing rapid flame spread. And the co polymerized all bromine polyester flame retardant yarn has a tight bond between the flame retardant components and fibers, and can still maintain good flame retardant performance after 35-50 washes, avoiding the problem of frequent use or ineffective flame retardant effect after cleaning.
Retaining the basic physical properties of polyester: It basically continues the advantages of high strength, wear resistance, and wrinkle resistance of ordinary polyester yarn. The fabric made from it has strong tensile and tear resistance, and can withstand friction and external pulling in high-frequency use scenarios such as workwear and industrial fabrics. It is not easy to deform after long-term use. At the same time, it has good weather resistance and a certain tolerance to chemicals such as acids and alkalis. When exposed to outdoor or specific industrial environments for a long time, the fiber structure is not easily aged rapidly.
Strong processing adaptability: It can be woven separately into fabrics, or blended with fibers such as cotton and viscose to optimize fabric feel, and is suitable for various processing methods such as knitting and weaving. Its dyeing performance is similar to ordinary polyester, and it can be made into multiple colors to meet the appearance design needs of different scenarios. Moreover, there is no need to significantly modify existing textile equipment during production and processing, which reduces the production adjustment costs of enterprises.
There are certain environmental and tactile shortcomings: these are its more obvious flaws. On the one hand, traditional bromine based flame retardants may release trace amounts of toxic gases during combustion. With the improvement of environmental standards, although environmentally friendly bromine based flame retardants are used, they are still not as environmentally friendly as halogen-free flame retardants such as phosphorus based ones. Some regions have certain restrictions on their use in civilian intimate areas; On the other hand, the addition of flame retardants will make the yarn feel slightly harder and less elastic compared to ordinary polyester yarn. The breathability of fabrics made from them will also slightly decrease, making them less suitable for making comfortable textiles such as underwear.
