Jilin Chemical Fiber successfully developed phosphorus-based solution-colored flame-retardant viscose fiber to fill the domestic gap
Recently, based on the successful development of phosphorus-based fire-resistant viscose fiber, Jilin Chemical Fiber Co., Ltd. has further developed phosphorus-based liquid-dyed fire-resistant viscose fiber mainly in black and supplemented by various color systems. This technology not only fills the domestic gap, but also breaks the foreign technology monopoly. It has also become a highlight of the development of new chemical fiber products in Jilin.
According to reports, Jilin Chemical Fiber’s fireproof viscose fiber is developed on the basis of its own phosphorus-based fire retardant DXL1212, which has independent intellectual property rights for viscose. The DXL1212 fire retardant is produced by Jilin Chemical Fiber Co., Ltd.’s holding subsidiary Jilin Chemical Fiber Co., Ltd. Li Chemical Co., Ltd. is also the only professional manufacturer of fire retardants in China. It is an important manufacturer in the world that realizes industrial production besides Klein Company.
Since 2008, Jilin Chemical Fiber has used three years to successfully complete the entire process from the development of fire retardant agents to small tests, pilot tests and industrial production of fire retardant fibers. The product quality has reached the domestic advanced level and has been recognized by users. Starting from the second half of 2011, the company began to research liquid-colored fire-resistant viscose fibers, and successfully realized industrial production in March 2012. At present, the company has developed liquid-colored fire-resistant fibers as the main component and supplemented by different colors. Fire-resistant viscose fiber system.
Xia Yucong, deputy chief engineer of Jilin Chemical Fiber Co., Ltd., said that during the development process, the company’s R&D team overcame many technical difficulties. Phosphorus-based fireproof fiber is one of the important differentiated varieties of viscose fiber. It is also a fiber variety with particularly high technical content. This is mainly because there are many difficulties in the graft copolymerization of natural cellulose molecules. The current fire-resistant viscose fibers adopt the blending method. However, because the amount of fire-retardant added is particularly large, it brings many unfavorable factors to actual production, which is harmful to actual production. Product quality has a great impact. If coloring pigments are added, its production will become more difficult, especially the strength of the fiber will be greatly damaged. In order to solve this production problem, the R&D team has developed nanotechnology, emulsification and dispersion technology, high wet modulus fiber technology, etc. After half a year of small and pilot tests, the above problems were successfully overcome. The important indicator of this fiber is the limiting oxygen index LOI value of more than 28, the strength of the finished product can reach more than 2.0CN/dtex, and the spinnability is stable. The product trial spinning meets user requirements.
Dope-dyed fire-resistant viscose fiber has the common advantages of fire-proof fibers and dope-dyed fibers. The colorant of the fiber is directly combined with ordinary cellulose during the fiber forming process. Therefore, compared with post-dyed fiber, it is not only dyed but also dyed. It has high fastness and avoids serious environmental pollution caused by dyes used in downstream dyeing and finishing processes. Its important fire protection function is low smoke, non-toxic, non-melting and dripping, fire and heat resistant, etc., which can ensure the safety of users to the greatest extent, provide all-round love protection, and cleaning and friction will not affect the fire protection effect. . In addition, this fiber also maintains the original excellent properties of viscose fiber, has good moisture absorption and drainage properties, is comfortable and breathable to wear, and facilitates the discharge of sweat in high temperature environments. In addition, its waste can be naturally degraded and meets environmental protection requirements. The phosphorus-based fire protection also meets the EU’s fire protection and halogen-free requirements.
Dope dyed fire-resistant viscose fiber can be blended with wool, PODLON, Nomex, fire-resistant vinylon and other high-performance fire-resistant fibers to blend chemical fiber fabrics, and is mainly used in the field of fire-resistant protective clothing. Fire-resistant protective clothing is essential work clothing for factory production, fire brigade and military. It can provide short-term fire protection against flames when metal sparks fly and there is a fire danger. At the same time, it improves the wearing comfort with its excellent moisture absorption performance. It still has a soft and smooth feel, bright colors and perfect fire resistance after being washed many times. Therefore, it can also be used in underwear and home furnishing fields, and has good development potential. prospect.
