Description

A kind of flame-retardant yarn and preparation method thereof
Technical field
The present invention relates to textile yarn technical fields, specifically, being related to a kind of flame-retardant yarn and preparation method thereof.
Background technology
Common fabric yarn fire resistance is not up to standard, needs to do flame-retardant after-finishing, on the one hand increases cost, on the other hand hinder Fabric feeling is deteriorated after combustion processing, influences properties of product.Traditional flame-retardant yarn mainly by dipping fire retardant method, the disadvantage is that The not all right flame retardant effect of one side fastness is poor, is also difficult in the fabric production in later stage.Therefore, exploitation one kind does not need fire-retardant The yarn of processing can reach flame retardant property and fabric feeling, there is prodigious application prospect.
Invention content
In view of the drawbacks of the prior art, the object of the present invention is to provide a kind of flame-retardant yarns and preparation method thereof.
The purpose of the present invention is what is be achieved through the following technical solutions：
The present invention provides a kind of flame-retardant yarns, include each component of following mass percentage：
Graphene composite fibre 60~70%；
Acrylic fibers oxidization fiber fiber 10~20%；
Polytetrafluoroethylene fibre 10~20%.
Preferably, the graphene composite fibre is prepared by the method for melt spinning；In the graphene composite fibre, The mass content of graphene is 1-5%.More preferable content is 2-5%.
Preferably, in the graphene composite fibre, graphene include do not aoxidize unmodified graphene, graphene oxide, At least one of surface modified graphite alkene.More preferable graphene oxide, surface modified graphite alkene；Most preferably surface modified graphite Alkene.
Preferably, the acrylic fibers oxidization fiber fiber, since its fiber surface is smooth, frictional force is small, is typically used as non-woven fabrics It makes, it is difficult to be used for the making of fabric yarn.The acrylic fibers oxidization fiber of the present invention is prepared by special method for oxidation；The fiber into The initial temperature of row oxidation is 220 DEG C, increases 5 DEG C within every ten minutes, until temperature is taken out when being increased to 250-260 DEG C, terminates oxygen Change.The oxidizing temperature is excessively high or heating is too fast, and fibers carbonization degree can be caused excessively high, and fiber strength declines, in weaving process The middle cohesive force for influencing fiber, is unfavorable for spinning；Oxidizing temperature is too low or heats up slowly, can lead to flame-retardant fiber poor performance, makes At yarn flame retardant effect it is bad.
Preferably, the intensity of the acrylic fibers oxidization fiber is 1.80-1.94cN/dtex, elongation 18.9-21.9%, LOI Value is 49-50%.
Preferably, the intensity of the polytetrafluoroethylene fibre be 17.7~18.5cN/dtex, elongation percentage be 25%~ 50%, can tolerate temperature is 120-180 DEG C, and limit oxygen index LOI is 90%.
The present invention also provides a kind of preparation method of flame-retardant yarn, the method includes：By graphene composite fibre, nitrile After synthetic fibre oxidization fiber fiber and polytetrafluoroethylene fibre mix in proportion, spin to get.
Preferably, the method for the spinning is using air spinning, half one or more of spinning, spinning.
Compared with prior art, the present invention has following advantageous effect：
Being combined using acrylic fibers preoxided thread, graphene composite fibre and polytetrafluoroethylene fibre for the present invention increases yarn Flame retardant effect, flame retardant property LOI values can achieve the effect that 40% or more reaches non-ignitable.The basic nature of yarn is kept simultaneously Can, fabric can be made.
