Production method used for fire scene escaping safety rope

Abstract

The invention discloses a production method used for a fire scene escaping safety rope. A sheath is made of temperature resistance heterocyclic copolymerization aramid fiber yarns in a twisting mode. According to a core, flame retardant polyester fiber yarns are twisted and then preprocessed, while the heterocyclic copolymerization aramid fiber yarns and the flame retardant polyester fiber yarns are knitted through a knitting machine, a flame retardant adhesive is added, then heat shaping is performed, and the sheath and the core are combined. The production method is high in safety factor, good in performance and high in intensity.

Description

technical field [0001] The invention relates to a safety rope, in particular to a production method for a fire escape safety rope. Background technique [0002] With the development of the economy, especially the increase of high-rise buildings, the frequency of fires is getting higher and higher, and some fire escape tools are urgently needed. As a necessary tool for fire escape, safety rope has more and more important properties of fire prevention and flame retardancy. At present, there are two main types of fire escape safety ropes: fiber safety ropes and steel wire safety ropes, each with its own advantages and disadvantages. Fiber safety ropes are easy to carry, but have poor fire and flame retardant properties; safety ropes containing steel wires have good flame retardant properties, but they are easy to conduct heat, have poor flexibility, are not easy to bend, and are relatively heavy. For example, invention patent 201210440518.8 discloses a "self-rescue rope". One...
