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
The present invention relates to a kind of safety rope, especially a kind of production method for the escape from fire safety rope.
Background technology
Along with expanding economy, especially skyscraper no matter increase, the frequency that fire occurs is more and more higher, in the urgent need to the escape from fire instrument of some.Safety rope is as the instrument of escape from fire indispensability, and its fire prevention and fire resistance are also more and more important.At present the fire disaster escaping safety rope mainly contains two classes: fiber safety rope and containing the steel wire safety rope respectively has quality.The fiber safety rope is convenient for carrying, but fire retardant performance is poor; The shortcomings such as the safety rope fire resistance containing steel wire is good, but is easy to conduct heat, and pliability is poor, not flexible, that weight ratio is heavier.For example, patent of invention 201210440518.8 discloses a kind of " rope of saving oneself ", and an end of rope body is fixedly connected with a joint, and joint is steel loop, and the feature of not mentioned rope body own.Utility model patent 201220203654.0 discloses a kind of " fire disaster escaping rope ", use be steel wire rope.Utility model patent 200920047294.8 discloses a kind of " fire-fighting escape rope ", and inner core is steel wire or wirerope, and the outsourcing thing is that nylon wire is formed by weaving.The general flow of the kernmantle of core-skin combination is: then Yarn twisting weaves.Core twist thread and without preliminary treatment, core-skin in conjunction with the time also needn't process through fire retardant adhesive.
Summary of the invention
The objective of the invention is: the production method for the escape from fire safety rope that a kind of safety coefficient is high, performance good, intensity is high is provided.
For achieving the above object, the technical scheme that the present invention takes is: skin and core two parts yarn are by weaving, being bonded, and skin is to be made by temperature tolerance heterocycle copolymerization aramid fiber Yarn twisting, and the twist of heterocycle copolymerization aramid fiber yarn is 30～50 twist with the fingers/rice; Core is first to be twisted and then passed through preliminary treatment by the fire-retardant polyester fibre yarn, the first twist S of described fire-retardant polyester fibre yarn is twisted as 130～150 twist with the fingers/rice, retwist Z is twisted as 90～110 twist with the fingers/rice, after having twisted, the NaOH solution-treated 20～30min that is 0.8-1.2% through the concentration of 95～100 ℃, process washing later, remove residual alkali post-drying; Heterocycle copolymerization aramid fiber yarn and fire-retardant polyester fibre yarn add fire retardant adhesive when weaving by braiding machine, then through HEAT SETTING, make the core-skin combination.
Described fire retardant adhesive is annular phosphate class organic compound.
The invention has the beneficial effects as follows:
1, fire protection flame retarding: the present invention is because skin adopts temperature tolerance heterocycle copolymerization aramid fiber, and core adopts fire-retardant polyester fibre, and skin and core are bonded by annular phosphate class fire retardant adhesive, have the function of multiple fire protection flame retarding.2, high temperature resistant: skin, as the bearing layer of this safety rope, can be used continuously between-200 ℃～250 ℃, has good resistance to elevated temperatures, and whole rope body also can be used continuously 10 hours between-150 ℃～250 ℃.3, heat transfer coefficient is low: skin is as the bearing layer of this safety rope, and the heat transfer coefficient of temperature tolerance heterocycle copolymerization aramid fiber only has 0.04W/ (m K), and 48.5 W/ (m K) far below steel wire, when librarian use, play adiabatic protective effect.4, intensity is high: the live load that the rope body bears in the time of 200 ℃ is 200KG～300KG, and safety coefficient is 10:1.5, economical and practical: whole safety rope body only has 40%～50% of steel wire rope cost.The advantages such as product of the present invention has fire protection flame retarding, high temperature resistant, heat transfer coefficient is low, impact resistance is good, good stability of the dimension, can help people's escape unharmed scene of a fire, has good economic benefit and social benefit.
The accompanying drawing explanation
Fig. 1 is product structure schematic diagram of the present invention.
The specific embodiment
Fig. 1 is product structure schematic diagram of the present invention, illustrates by reference to the accompanying drawings the present embodiment.Temperature tolerance heterocycle copolymerization aramid filament is a kind of high-performance fiber, have good fire protection flame retarding, high temperature resistant, do not conduct heat, the performance such as intensity height.Research shows that temperature tolerance heterocycle copolymerization aramid fiber has increased substantially the strength and modulus of fiber, 250 ℃ of lower thermo-oxidative ageing experiments, show after 192 h are aging, strength retention, 60%～80%, illustrates that temperature tolerance heterocycle copolymerization aramid fiber is better than the thermo oxidative stability of general fibre.
A kind of production method for the escape from fire safety rope, skin 1 and core 2 two parts yarns are by braiding, be bonded, skin 1 is to be made by temperature tolerance heterocycle copolymerization aramid fiber Yarn twisting, temperature tolerance heterocycle copolymerization aramid filament is twisted into yarn through adding, the fineness of yarn is between 4000D～5000D, the twist is 30～50 twist with the fingers/rice, sth. made by twisting is to twisting with the fingers for S or the Z sth. made by twisting, then be wrapped on the spool of braiding machine, difference according to the braiding machine model, the spool of braiding machine has 12～48, on braiding machine, these spools are responsible for making the skin portion of safety rope, 40%～50% of the shared rope body of heterocycle copolymerization aramid fiber skin gross weight, it is the bearing layer of whole rope body.Core 2 is first to be twisted and then passed through preliminary treatment by the fire-retardant polyester fibre yarn, the fire-retardant polyester fibre long filament is first twisted and is made yarn through twice, the first twist S of fire-retardant polyester fibre yarn is twisted as 130～150 twist with the fingers/rice, retwist Z is twisted as 90～110 twist with the fingers/rice, the fire-retardant polyester fibre fineness of yarn of making is between 20000D～30000D, after having twisted, the NaOH solution-treated 20～30min that is 0.8-1.2% through the concentration of 95～100 ℃, process fully washing later, remove residual alkali post-drying, pretreated purpose is to change the poor shortcoming of polyester fiber water imbibition, effectively remove the impurity of fabric face, improve bonding effect.At 12～48 heterocycle copolymerization aramid yarns of knitting process as rubber-insulated wire, 7～14 flame retardant polyester yarns as heart yearn, add fire retardant adhesive in braiding, this fire retardant adhesive is annular phosphate class organic compound, then through HEAT SETTING, core-skin is better combined.
