Abstract
The fireproof extra fine polyester fiber includes main polymer component and phosphorus fire retardant. It is produced through adding phosphorus fire retardant into polymer material, melting and spinning to obtain grey yarn, and further winding and drafting to obtain the fireproof extra fine polyester fiber. The fireproof extra fine polyester fiber has excellent spinnability, physical performance similar to that of common extra fine polyester fiber and excellent fireproof effect.
Description
Technical field:
The invention discloses a kind of fire-retardant polyester fibre and manufacture method thereof.
Background technology:
Polyester fiber (being terylene) has the intensity height, good springiness, and wrinkle resistance is strong, dimensionally stable, good, the stable chemical performance of ABRASION RESISTANCE, quick-drying washable, performance such as heat resistance and weather fastness are good.Therefore, it is all well received to be used for civilian and industry, is a kind of comparatively ideal textile material.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 nap fabric 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 high molecular polymer have flame resistance, 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 and production method of good flame retardation effect.
Technical solution of the present invention is:
A kind of flame-proof polyester superfine fibre comprises main polymer, it is characterized in that: contain phosphorus flame retardant in main polymer.
Main polymer 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.
Phosphorus flame retardant is 2-carboxyethyl benzenephosphonic acid, 2-carboxyethyl methylphosphinate phosphate or 2-carboxyethyl methylphosphinate phosphoric acid, and its corresponding structural formula is respectively:
Phosphorus content is 3000-7000ppm, TiO
2Content is 0.05-2.5wt%.
Filament number≤1 Denier, limited oxygen index LOI 〉=28% of final gained fiber.
A kind of production method of flame-proof polyester superfine fibre is characterized in that: make by single composition spinning or composite spinning method.
The concrete grammar of single composition spinning is: the polyester slice that will contain phosphorus flame retardant enters screw extruder, but become the polyester fondant of spinning through the melt extruded of screw extruder, and this polyester fondant is transported in the spinning manifold, and further be evenly distributed in the assembly, handle through preliminary draft, false twisting, go forward side by side a step reel, interlacing handles, finished product.
The melt extruded process of screw extruder is provided with 3～5 sections thermals treatment zone, and the heating-up temperature in each district is located between 260～285 ℃; Spinning body temperature is located at 260～285 ℃.
The concrete grammar of composite spinning method is:
1. be first raw material with the soluble-type polyester slice, enter first screw extruder, but become the polyester fondant of spinning through the melt extruded of first screw extruder, and this polyester fondant is transported in the spinning manifold, and further be evenly distributed in the composite component, become the compound sea component in island or cut fine compound a kind of composition;
2. be second raw material with the polyester slice that contains phosphorus flame retardant, enter second screw extruder, but become the polyester fondant of spinning through the melt extruded of second screw extruder, and this polyester fondant is transported in the spinning manifold, and further be evenly distributed in the composite component, become the compound island component in island or cut fine compound another kind of composition;
3. two kinds of compositions of moulding in the composite component are extruded, handled through preliminary draft, false twisting, the step of going forward side by side reels, interlacing is handled, finished product, the gained finished fiber obtains filament number≤1 Denier by decrement treatment.
Step 1. in the melt extruded process of first screw extruder be provided with 3～5 sections thermals treatment zone, the heating-up temperature in each district is located between 250～285 ℃; Step 2. in the melt extruded process of second screw extruder be provided with 3～5 sections thermals treatment zone, the heating-up temperature in each district is located between 260～285 ℃; Spinning body temperature is located at 260～285 ℃; Spinning speed is controlled to be 1500～4000m/min; The drawing-off multiplying power of false twisting processing is 1.5～3.5, and heter temperature is 130-200 ℃.
Flame-proof polyester superfine fibre 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.
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%.
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 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.
Product of the present invention has the better spinnability energy, and physical property is close with general polyester superfine fibre and have a good flame retardant effect.The flame-proof polyester superfine fibre fiber number that makes is thin, powerful big, and has the good flame-retardance energy.
The invention will be further described below in conjunction with embodiment.
