The invention is realized by the following technical scheme:
a novel high-comfort flame-retardant yarn is prepared by blending aramid 1313 fibers, flame-retardant viscose fibers, aramid 1414 fibers and conductive fibers; in the flame-retardant yarn, the weight percentage of the aramid 1313 fiber is 20-95%, the weight percentage of the flame-retardant viscose fiber is 10-70%, the weight percentage of the aramid 1414 fiber is 5-10%, and the weight percentage of the conductive fiber is 1-5%.
The aramid 1313 fiber, the flame-retardant viscose fiber, the aramid 1414 fiber and the conductive fiber are woven into the high-comfort flame-retardant yarn through ring spinning, and the ring spinning is a mechanical spinning method which is formed by twisting a spindle, a ring and a traveler and drafting through a roller. The fiber strips after the slivers or the rough yarns are drafted are led in through the ring traveler in a rotating mode, the winding speed of the bobbin is higher than that of the traveler, and the fiber rough yarns are twisted to form spun yarns. The steel wire ring is driven by the bobbin to rotate around the steel collar through the yarn to twist, and meanwhile, the friction of the steel collar enables the rotating speed of the steel wire ring to be slightly less than that of the bobbin to be wound, so that the spinning speed is high. The yarn is woven by ring spinning, the shape of the yarn is a conical spiral line with fibers transferred inside and outside, the fibers are wound and connected inside and outside the yarn, and the yarn is compact in structure and high in strength, and is suitable for spinning high-strength comfortable flame-retardant yarns.
The aramid 1313 fiber is a polyamide fiber, which is prepared by solution spinning after condensation polymerization of m-phenylenediamine and isophthaloyl chloride, the breaking strength reaches 0.4-0.53N/tex, the elongation reaches 30-50%, and the aramid fiber is resistant to acid, alkali, mildew and aging. The aramid fiber 1313 has complex production process and great technical difficulty, the prepared fiber has lasting thermal stability and unique and stable chemical structure, the fiber starts to decompose at the temperature of more than 370 ℃, the fiber starts to carbonize at about 400 ℃, the limiting oxygen index is more than 28 percent, and the fiber is not easy to burn; the low rigidity and high elongation characteristics of the fiber enable the fiber to have the same spinnability as common fiber.
The viscose fiber is made up of natural fibre through alkalization, ageing and sulfonating to obtain soluble cellulose xanthate, dissolving in diluted alkali solution to obtain viscose fibre, and wet spinning. By adopting different raw materials and spinning processes, common viscose fibers, high wet modulus viscose fibers, high strength viscose fibers and the like can be obtained respectively. The common viscose fiber has common physical and mechanical properties and chemical properties, and the flame-retardant viscose fiber meeting the flame-retardant standard is obtained by treating the common viscose fiber and a flame retardant through a graft copolymerization method, a post-finishing method and other methods, has excellent air permeability and moisture absorption performance, is easy to dye, is difficult to generate static electricity, has better spinnability, and can improve the mechanical properties, the comfort performance and the like of fabrics by blending with other fibers.

Has high heat resistance, glass transition temperature over 300 deg.c, thermal decomposition temperature up to 560 deg.c, high tensile strength, high initial elastic modulus, stable heat shrinkage and stable creep performance.
The conductive fiber is a chemical fiber, a metal fiber, a carbon fiber, or the like spun by mixing a conductive medium into a polymer. The antistatic fiber has excellent performance of eliminating and preventing static far higher than that of antistatic fiber, and is prepared by adding conductive media such as carbon black, graphite, metal powder or metal compound into fiber by methods such as mixing, evaporation, electroplating and composite spinning. The fabric mixed with a small amount of conductive fibers can be used as special work clothes, protective clothes and the like.
According to the invention, the aramid fiber 1313 fiber, the flame-retardant viscose fiber, the aramid fiber 1414 and the conductive fiber are blended to form the high-comfort flame-retardant yarn, and the content of the aramid fiber 1313 fiber and the flame-retardant viscose fiber is changed, so that the fireproof performance and high strength of the aramid fiber 1313 fiber can be well utilized, and the comfort performance of the flame-retardant viscose fiber can also be utilized.
