The invention provides a fire-retardant anti-molten droplet fiber, a method for preparing the same and application thereof. The fire-retardant anti-molten droplet polyester fiber is prepared by adopting a sheath-core composite spinning method, wherein the sheath of the fiber is made of the polyphenylene sulfide (PPS) fiber, and the core of the fiber is made of the fire-retardant polyester; when the composite fiber is fired, no molten droplet phenomenon is generated; moreover, the fire-retardant anti-molten droplet fiber has quite good fire-retardant property and strong industrial practicability.
Description
Technical field
The present invention relates to a kind of fire-retardant anti-molten droplet fiber, its preparation method and application thereof, especially a kind of fire-retardant anti-molten droplet fiber with skin-core structure.
Background technology
Terylene (PET) is a kind of synthetic fiber with fastest developing speed in the various synthetic fiber, that output is the highest, application surface is the widest, and its fiber textile is used for dress material, curtain, curtain, bedding, interior decoration and various special material in a large number.But because the limited oxygen index (LOI) of terylene is about 21, along with the extensive use of fabric, the potential danger of its fire also becomes increasingly conspicuous.The maximum shortcoming of polypropylene fibre (PP) is inflammable, the not only decomposition combustion of being heated, and fusion drippage, and the temperature of molten drop is very high, makes the people be subject to scald during as clothes, has also limited its application in fields such as buntings simultaneously.Build, commercial mansion, airport, auditorium, indoor public place of entertainment, traffic and transport field.But terylene belongs to the inflammability fiber, and its limited oxygen index has only about 22%, can not satisfy the requirement of some fields to fire resistance, and it is carried out the fire-retardant very necessity that just seems.The particularly important is, can produce serious molten drop phenomenon during the terylene burning,, help the fire-retardant of terylene though this molten drop can be taken away a part of heat from polymeric substrate; But molten drop can bring more serious disaster.At first, some molten drops (even fireless molten drop) that have flame are very easy to the material on every side that ignites as second burning things which may cause a fire disaster, thereby have quickened the expansion of flame propagation and fire scale; Secondly, making skin be exposed under flame and the radiation of heat after the fusion comes to harm; If the material of fusion is bonded on the skin, may make skin scald; The latent heat of emitting when the polymer of fusion solidifies again can make that also skin comes to harm, and removes and be bonded at the polymer that has solidified on the skin and can increase the degree of burning, and this shows, being suppressed in terylene fire-retardant of molten drop occupies considerable status.
At present fiber is carried out flame-retardant modified method mainly by add fire retardant in polymerization or melting process, as patent US20040072929, CN02113512.6, CN200710015390.X, be published in the article " halogen-free flameproof, the experimental study of anti-drippage polypropylene fibre " on " Henan chemical industry ", this copolymerization method for modifying flame is that the synthesis phase at polyester carries out polycondensation and synthetic flame retardant polyester with fire-retardant monomer and polyester components, and then is spun into fire resistance fibre.Because fire-retardant monomer solid fixes on the polyester macromolecule chain, dissolving or osmotic phenomena in use can not take place, thereby this flame-resistant terylene has relative permanently, toxicity is lower.But in process of production the fire retardant that is added often influence fiber fastness to light reduce by 2～3 grades, cause the fiber flavescence, color worsens.Some halogen-containing fire proofings have easily been emitted excitant and corrosive hydrogen halide when burning simultaneously, produce noxious material, and life and property safety are constituted a serious threat.Simultaneously for the anti-molten drop of the high temperature of endowing terylene and fabric thereof, also need use additives such as nanoscale imvite, nano-class molecular sieve, silica, and naphthalene diacid, naphthalene two pure and mild glycerine isoreactivity monomers further improve the charing fire retardation, and cost is higher.
Another kind method is by carrying out fire-retardant post processing or carrying out graft copolymerization to carry out the surface treatment modification to fabric, as patent CN200610013529.2, grafting is flame-retardant modified to be fire-retardant monomer and the polyester generation graft copolymerization that makes vinyl-type with ultraviolet ray, high-power electron beam radiation or chemical initiator, be to obtain effective and lasting method for modifying flame, but require technical conditions and production cost all high, thereby be difficult for generally being adopted.Arrangement has simple, the low cost and other advantages of technology after the fabrics flame resistance, but lack fire-retardant persistence, and the fire retardant consumption is many, bigger to influences such as the intensity of fabric, feel, color and luster, gas permeabilities, as be numbered the article " novel organophosphorus ester is studied the fire-retardant and anti-molten drop of dacron " of 1009-5160 (2007)-0029-04; The advantage of finishing method is that technology is simple, and is with low cost, widely applicable, can satisfy fire-retardant requirement in various degree; Shortcoming is that the fire retardant consumption is big, and persistence is undesirable, and is bigger to the influence of physical and mechanical propertiess such as the brute force of fiber and fabric, feel.
The demand that therefore, the fire-retardant and anti-dripping fibre of development of new is still arranged.
