Abstract
The invention relates to high-temperature flame retardant fibers for wig, comprising the following components in parts by weight: 100 parts of polyester A, 5-30 parts of brominated polystyrene flame retardant B and antimony flame retardant C. The polyester A contains one or more kinds of polyterephthalic alkylidene ester or polyester copolymer taking the polyterephthalic alkylidene ester as a main body.
Description
Technical field:
The present invention relates to the polyester fiber of the anti-flammability made with polyester, brominated Polystyrene and antimony based flame retardant.Say in more detail, relate to have anti-flammability, fiber properties such as heat resistance, intensity, percentage elongation; High-temperature flame retardant fibers for wig drapability and that have sub dued lustre smooth, good with softness.
In addition, the present invention relates to the profiled-cross-section fiber, say in more detail, relate to as artificial hair fibers such as wig, headwear wig, the profiled fibre that has gloss, color and luster, feel and the smooth property of people Zhen Fa simultaneously.
Background technology
Pet fiber or based on polyethylene terephthalate, polytrimethylene terephthalate and polybutylene terephthalate (PBT) are the polyester fiber of submember, because have high-melting-point, high strength and modulus, high-temperature resistant and excellent chemical-resistant, it extensively is applied to taking aspects such as fiber, cord fabric thread, strap, curtain, decorating cloth, automotive fabrics interior trim, artificial hair, filter net cloth, bituminous concrete supporting material and uses.
On the other hand, pass by that the hair product end user of wig, headwear wig, hair band, rag baby wig etc. really sends out in the past or artificial fibre wig (as polypropylene fibre, polyvinyl chloride fibre and polyacrylonitrile fibre) etc.But because the true relatively difficulty of purchase of sending out, so people turn to fiber for artificial hair with emphasis gradually.Though have flame-retarding characteristic through flame-retardant modified polyacrylonitrile fibre and polypropylene fibre, the heat resistance aspect is then undesirable.
In recent years, people's polyethylene terephthalate of having proposed to use good heat resistance is the polyester fiber of the representative direction as the fiber for artificial hair of main component.Yet,, undesirable on anti-flammability owing to the polyester fiber that with the polyethylene terephthalate is representative is a combustible material.
As everyone knows, the past people have carried out the exploration of various raising polyester fiber anti-flammabilitys.For example make the method for fiber by 1. flame retardant polyesters that contain the fire retardant comonomer copolymerization of P elements; 2. or the polyester fiber method of putting in order after with fire retardant; 3. polyester fiber and fire retardant co-blended spinning are made the method for fiber.
The flame retardant polyester that contains the fire retardant comonomer copolymerization of P elements as first kind use is made the method for fiber, for example uses the method (CN 101200820A) of phenyl-(propionic acid ethylene glycol ester group) hypophosphorous acid as the comonomer copolymerization; Also proposed the flame retardant polyester method of phosphonium flame retardant comonomer copolymerization, wherein phosphorus content 500～50, and 000ppm and content are 500～50, and the 000ppm carbon black prepares black flame-retardant polyester fiber (CN101084331).Ring-type phosphorus compound or phosphate have also been proposed
Yet artificial hair requires than higher anti-flammability.Therefore the copolymerization fire resistance fibre need increase the copolymerization amount of phosphorus flame retardant during with fiber as artificial hair.And this can significantly reduce the heat resistance and the intensity of polyester fiber.Melt spinning becomes difficult simultaneously.Though missing of ignition burning in the time of perhaps near flame can produce the fusion drippage.The fire-retardant polyester fibre of copolymerization simultaneously is clamminess in addition and feels and bad fiber problem of appearance.
As second kind of use is to adopt on the surface of polyester fiber to immerse spray method coating one deck phosphorus flame retardant or halogen flame retardant.(CN 1111304A); Also proposed phosphorous flame-retardant liquid polyester fiber has been flooded, under the condition of normal pressure or pressurization, polyester fiber has been handled then, to give the polyester fiber anti-flammability.(CN 101133204); The fire retardant that has also proposed to contain aromatic group and phosphinylidyne structure is handled (CN 101253184A) to polyester fiber.
Yet, adopt dipping, pressurized heat to handle the fire retardant method, in order to obtain enough anti-flammabilitys, there is the problem that must use a large amount of fire retardants for a long time at 150 ℃ of left and right sides high temperature.Produce that fibrous physical property reduces greatly, production cost increases, environment is unfriendly and flame retardant effect can not keep for a long time, not water-fast problem such as wash.
What make that the method for fiber uses as the third polyester fiber and fire retardant co-blended spinning is the composition that polyester, ring-type phosphorus compound or phosphoric ester amides compound and inorganic particles melting mixing obtain, and holds melt spinning (CN100415958C) then; The method of spinning after polyester and brominated oxidative ethane fire retardant and the blend of organic-inorganic powder has also been proposed, to give polyester fiber anti-flammability (CN101250766A).
The method that more than prepares fire resistance fibre all exists as artificial hair fiber or anti-flammability or intensity or temperature tolerance or cardability deficiency.Or cost price is high and operation implementation method complicated problems.All there is certain defective.
The present invention adopts the polyester A that contains at least a polymer in polyethylene terephthalate, polytrimethylene terephthalate and the polybutylene terephthalate (PBT) with brominated Polystyrene based flame retardant B and antimony compounds C melt spinning, adds color master-batch D simultaneously and carries out painted to fiber.Have simple to operate, anti-flammability is high, fibre strength is high, temperature tolerance is high, the cardability drapability is good and with true send out near etc. advantage.
