Abstract
The invention relates to an environmentally friendly flame-retardant polyester bulk deformation yarn with a good flame-retardant effect and a preparation method thereof, wherein the yarn comprises 86-88% of polyethylene glycol terephthalate, 11-13.9% of tricresyl phosphate, 0.1-0.7% of ethylene glycol antimony and 0.03-0.3% of 2-tert-butyl-hydroquinone. The yarn and the preparation method provided by the invention have the advantages that first, the actual P content in the final product is more than 17,000 ppm and the limiting oxygen index is over 56% so as to achieve the purpose of permanent flame retardance, and the flame-retardant effect is far better than that of similar flame-retardant polyesters at home and abroad; and second, the yarn is environmentally friendly as no gases which cause environmental pollution are produced in flame-retardant process.
Description
Technical field
The present invention relates to a kind of environmental-protection flame-retardant terylene varicosity textured filament yarn and the preparation method with good flame retardant effect, belong to fire-retardant yarn and manufacture field.
Background technology
CN101230500A, title " a kind of flame-proof antibiotic terylene case yarn ", it adopts spins production method with common section after fully mixing with section produce fire-retardant, antimicrobial nano powder.In process of production, employing special process parameter, linear density to the end value controlling silk is 250D ~ 1000D, breaking tenacity reaches more than 6.5CN/DTEX, and dry-hot shrinkage controls between 3 ~ 6%.
CN101280522A, title " a kind of high-strength wear-resistant fabric for cases and manufacture method thereof ", adopt powerful index to weave and through the coated fabric made by one side coating at the high-strength terylene filament of more than 7.5CN/DTEX; Warp thread adopts high-strength terylene filament air deformation yarn, and weft yarn can be other form of yarns of high-strength terylene filament.This high-strength wearable fabric possesses high tensile strength, high tearing brute force, high-wear resistance, and stamp is clear, colour fastness is good, coloured light is excellent, is made that fabric has waterproof concurrently, fire-retardant, camouflage, anti-infrared such as to detect at the performance by finishing functions.
CN101245516A, title " production method of a kind of fire-retardant yarn and fabric and this fire-retardant yarn ", rove and spun yarn is become by the flame-retardant acrylic fibre fiber of weight 40 ~ 99% and the Persian synthetic fibre fiber successively blending of weight 60 ~ 1%, spun yarn winder is obtained fire-retardant yarn, with this fire-retardant yarn by ordinary method woven into fabric.Fire-retardant yarn of the present invention and fabric thereof maintain acrylic fiber composition good permanent fire-retardant, heat retention good, the advantageous characteristic such as quality is light, maintain again the advantageous characteristic such as wear-resisting, well-pressed, the anti-wrinkle in Persian synthetic fibre fiber (modified polyester fibre), and during burning, only have ashes, do not produce to melt and drip thing, fundamentally prevent human body of burning.
Summary of the invention
Purpose of design: design a kind of environmental-protection flame-retardant terylene varicosity textured filament yarn and the preparation method with good flame retardant effect.
Design: in order to realize above-mentioned purpose of design.The application adopts antimony glycol and 2-Tert. Butyl Hydroquinone as compound system, this compound system can break through the limited situation of copoly type amount of flame-retardant agent, significantly improve the effective level of fire retardant, make the bottleneck of the actual phosphorus content of current phosphor-containing flame-retardant copolyester lower (generally can only at 5600 ~ 7500ppm), the actual P content of the finished product can reach more than 17000ppm, limiting oxygen index(LOI) can up to 56%, and for permanent fire-retardant, and flame retardant effect is much better than domestic and international similar flame retardant polyester.The application, after chance fire, containing the segment of ignition-proof element under high temperature action, forms the polyphosphoric acid with strong dehydration on the one hand, makes its rapid dehydration and form fine and close carbon-coating on surface, hinders oxygen to spread to reaction zone; Degradation production on the other hand in combustion processes can H and the OH high mars free radical that produces of cancellation, and flame is extinguished rapidly; Meanwhile, the difficult burning smoke mist of generation then can diluting reaction district inflammable gas, reaches fire-retardant object.
Technical scheme 1: a kind of environmental-protection flame-retardant terylene varicosity textured filament yarn, weight percent is: the polyethylene terephthalate containing 86 ~ 88%, 11 ~ 13.9% Tritolyl Phosphates, the antimony glycol of 0.1 ~ 0.7% and the 2-Tert. Butyl Hydroquinone of 0.03 ~ 0.3%.
Technical scheme 2: a kind of preparation method of environmental-protection flame-retardant terylene varicosity textured filament yarn, by band active function groups phosphorous copoly type compound be fire retardant, after the process of esterifying polycondensation reaction process, under the effect of catalyzer and auxiliary agent, there is esterifying polycondensation with polyethylene terephthalate to react, generate halogen-free antiflaming polyester copolyester, because fire retardant and terephthalic acid, ethylene glycol there occurs copolyreaction, make ignition-proof element P be linked in polyester macromolecule chain, form the polyester with essential permanent flame retardant effect.
The present invention is compared with background technology, and one is that the content of actual P in the finished product can reach more than 17000ppm, and limiting oxygen index(LOI), up to more than 56%, achieves permanent fire-retardant object, and flame retardant effect is much better than domestic and international similar flame retardant polyester; Two is environmental protection, can not produce the gas of environmental pollution time fire-retardant.
