Abstract
The invention discloses a flame retardant polyester ultrafine fiber file fabric which is characterized in that the fabric contains ultrafine flame retardant polyester fibers, and a fiber monofilament denier is less than or equal to one Daniel. The invention has the advantages of good weavability, similar fabric physical property as that of general fabrics, good hand feeling and excellent flam retardant effect.
Description
Technical field:
The present invention relates to a kind of flame-retardant fibre fabric.
Background technology:
Polyester fiber belongs to the meltbility combustible fibre, expansion along with its Application Areas, in some special use occasion, as aviation, public place of entertainment, family's decorations art work or the required aspects such as protective clothing of some special industry, then require to reach certain fire-retardant requirement, otherwise will improve the insecurity of fire greatly.Moreover, these polymer under burning or high temperature also can fusion drippage, thereby limited their use in some occasion.
Existing fleece is that common polyester filament makes, because fluffing part fiber number is less, is exposed to fully under the situation of air, runs into naked light and burning and be large-area burning in the short time easily thereof.In addition, the filament number of existing fire resistance fibre is thicker, is not suitable for fluffing processing.
In order to make fleece have anti-flammability, the feasible exactly high molecular polymer that constitutes the superfine fibre of nap fabric has anti-flammability, just need carry out fire-retardantization to it.At present macromolecular material is carried out fire-retardantization two kinds of methods are roughly arranged: a kind of is that copolymerization is flame-retardant modified, is about to fire-retardant monomer with the polymer monomer copolymerization; The 2nd, add fire retardant and carry out blending and modifying.But the fire resistance of prior art is still undesirable.
Summary of the invention:
The object of the present invention is to provide a kind of flame-proof polyester superfine fibre pile fabric of good flame retardation effect.
Technical solution of the present invention is:
A kind of flame-proof polyester superfine fibre pile fabric is characterized in that: this fabric contains superfine fire-retardant polyester fibre, fibre single thread fiber number≤1 Denier.
Limited oxygen index LOI 〉=28% of superfine fire-retardant polyester fibre.Its main body polyester polymers is polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate (PBT) or cation-modified polyethylene terephthalate, because polyethylene terephthalate spinning process maturation, cost is lower, excellent performance, preferred polyethylene terephthalate.
Fire retardant in the fire-retardant flame-proof polyester superfine fibre is 2-carboxyethyl benzenephosphonic acid, 2-carboxyethyl methylphosphinate phosphate or 2-carboxyethyl methylphosphinate phosphoric acid, and its corresponding structural formula is respectively:
(2-carboxyethyl benzenephosphonic acid) (2-carboxyethyl methylphosphinate phosphate) (2-carboxyethyl methylphosphinate phosphoric acid).P content is 3000-7000ppm in the superfine fire-retardant polyester fibre.Superfine fire-retardant polyester fibre shared proportion 〉=40% in whole fabric.Fabric is woven fabric and the knitted fabric through fluffing processing.
The flame-proof polyester superfine fibre of formation fleece of the present invention both can be the superfine fibre of common circular cross-section, also can be the superfine fibre at special-shaped interface, and described special-shaped interface comprises triangle etc.Superfine fibre both can obtain by single composition spin processes, also can obtain by composite spinning method.The fiber of different cross section can obtain by shape and the complex method that changes spinneret orifice.
Fleece of the present invention makes woven fabric or knitted fabric by using above-mentioned flame-proof polyester superfine fibre, fabric is fluffed handle or open earlier the processing of fluffing again of fine vehicle then, thereby make fire-retardant fleece.The fluffing processing method can adopt card clothing fluffing processing method, also can adopt processing methods such as the raising machine processing of thorn circle, card clothing fluffing processing, sand paper fluffing processing, and raising method also can be wet method, also can be dry method in addition.
Fire-retardant polyester fibre of the present invention both can also can be cut into slices with modification, as CDP (cationic-dyeable), ECDP polyester slices such as (normal temperature and pressure cationic-dyeables), to improve its dyeability or wearing comfort with conventional polyester slice.
In the fire-retardant superfine fibre, the P content of phosphorus flame retardant is 3000-7000ppm, TiO
2Content is 0.05-2.5wt%.
Production method of the present invention can adopt: the phosphorus that will form the fire resistance fibre main body is copolyester, carry out melt spinning, make the fire resistance fibre precursor, and further obtain the flame retardant polyester long filament, be i.e. the phosphorus based polyester flame-retardant superfine fibre through coiling stretching, interlacing, post processing; By the woven or knitting fabric that obtains, the fluff processing or open earlier and fine handle the processing of fluffing again and obtain fire-retardant fleece of gained fabric.
Flame-retarding phosphorus copolymerized section is to add fire retardant to make monomer (containing phosphorus series compound) in polyester slice production, produces fire-retardant slice by conventional copolymerization process.Phosphide mainly is fire-retardant by solid phase, impels fibrous carbon to divide and separates, and reduces the generation of fuel gas, thereby reaches fire-retardant purpose.
The fire-retardant extra fine filament of formation fleece of the present invention has good weaving properties, and physical property is close with general polyester superfine fibre and make the fluffing of fabric partly have good flame retardant effect.The fire-retardant fleece basic physical properties that makes is suitable with common fabric, and feel well also has the good flame-retardance energy simultaneously.
