Abstract
The preliminary oxidized filament fire-retardant fabric is made up by using preliminary oxidized filament as raw material through the processes of oiling, spreading, gilling, roving, finespinning, doubling and twisting, doffing and weaving. It is a characterized by that said tow conversion process includes two steps: first step is crimp thermosetting and second step is tow conversion by draft-cut. Its total woven yield is up to 75-78%, and the fire-retardant fabric has the good fire resistance, and its limiting oxygen index can be up to 40-50%. Said invention features simple process, low cost, simple crimp thermosetting machine structure and easy to be made.
Description
The invention belongs to a kind of textile technology and equipment, relate in particular to a kind of technology and equipment thereof of the pre-oxygen silk thermodurable textile of weaving.
Polyacrylonitrile (PAN) fiber obtains pre-oxidized fibers and (is commonly called as pre-oxygen silk, OF) after pre-oxidation process and device processes.The PAN fiber is in preoxidation process, its macromolecule linear molecule chain is converted into heat-resisting trapezoidal-structure, and give OF the not molten firing resistance that does not fire, the anti-combustion structure of this ladder type belongs to the anti-combustion structure of permanent type, do not change with space-time and washing, and taking is good, significantly is better than the various flame-retardant textiles of selling on the market of handling with fire retardant.Simultaneously, because the trapezoidal-structure of OF makes its rigidity big and flexible little, OF surface smoothing in addition causes between the OF filament cohesive force little, and spinnability is poor, gives spinning and weaves and bring many difficulties.In Chinese patent (CN1036235), in order to improve the spinnability of OF, with water-soluble organic fiber and OF blending resultant yarn with weave cotton cloth, and then water dissolve the organic fiber in weaving cotton cloth, obtain being similar to the pure OF fabric that spins.In this blending technology, organic fiber is just as the means of improving spinnability, add earlier and after remove, slattern organic fiber undoubtedly, must strengthen cost.In (GB2236772A) patent, pre-oxygen silk and aramid fiber blending are to improve spinnability and other performances; But the limited oxygen index of aramid fiber (LOI) is about 28, and the main performance index LOI of slow burning fabric is inevitable to descend along with the increase of aramid fiber amount.In achievement in research (achievement registration number 911411), adopted cotton type technology and equipment weaving OF slow burning fabric, be characterized in the OF that prescinds comb and parallel cotton fibers prior to spinning in comb and parallel cotton fibers prior to spinning is become net system bar, spin cotton and weave cloth then; Cohesive force is little because the OF rigidity is big, makes at carding process that OF shortens, suedeization or efflorescence, results in hand cramps not only for the system bar, and makes total row yielding low, has also strengthened cost price.
It is low to the purpose of this invention is to provide a kind of cost, easily the technology and the equipment thereof of the pre-oxygen silk of the weaving slow burning fabric of making.
The object of the present invention is achieved like this, be to adopt the wool type textile technology, but one-tenth net system bar technology that need not be traditional, and with crush cutting system bar technology.
Its processing step is pre-oxygen silk through oiling, make bar, pin stream, slubbing, finespun and the letter of picking up, fall, weaving step and make product, it is characterized in that described system bar is earlier through the HEAT SETTING of curling, and carries out crush cutting system bar again.
The aforesaid last oil mass that oils is the 0.3-0.9% of fibre weight.And finish contains the multicomponent mixture that antistatic additive, collecting agent, softener, moisture absorption increase rub agent and emulsifying agent.
The crispation number of aforesaid curling HEAT SETTING is 2-8/cm, has improved the cohesive force of fiber like this, has improved the fluffy state of strip, makes the strip compactness that makes.
Total crush cutting multiple of aforesaid crush cutting system bar is 2.5-4.5 times, and system bar speed is 10-25m/min, and crush cutting system bar is to adopt the multistage stretch breaking machine.
Necessary in order to achieve the above object curling heat setting machine is made up of deflector roll, electrocaloric effect, it is characterized in that electrocaloric effect is equipped with heating wire in both sides up and down, and front and back have into silk mouth, filament mouth, and deflector roll is positioned at into silk mouthful place.
In the time of need be fiber crimp, fiber be through deflector roll, advances silk and mouthful sends in the electrocaloric effect, and regulate a speed greater than wire vent speed, and the fiber that enters like this in the electrocaloric effect is curling naturally, again after heating wire adds HEAT SETTING, and the fiber that just can obtain curling from filament mouth.
Adopt technology of the present invention and curling heat setting machine can spin 64,32,16 count yarns, weave plain weave, twill and satin.
The present invention compared with prior art has following advantage:
(1) adopts crush cutting system bar technology, make total yield of knitting reach 75-78%.
(2) the slow burning fabric flame resistance that makes is good, and limited oxygen index can reach 40-50%.
(3) technology is simple, and cost is low.
(4) curling heat setting machine is simple in structure, easily manufactures.
Describe method of the present invention in detail and the heat setting machine that curls below by drawings and Examples.
Fig. 1 is the structural representation of curling heat setting machine of the present invention.
As shown in the figure, the 1st, fiber, the 2nd, deflector roll, the 3rd, electrocaloric effect, the 4th, the heating wire of electrocaloric effect both sides about in the of 3, the 5th, electrocaloric effect 3 advance silk mouthful, the 6th, the filament mouth of electrocaloric effect 3, deflector roll 2 are positioned at into silk mouthful 5 places.
In the time of need curling fiber 1, deflector roll 2 is sent into fiber 1 in the electrocaloric effect 3 to advance silk mouth 5, regulates the rotating speed of deflector roll 3, make into a speed greater than wire vent speed, the fibers that enter in the electrocaloric effect 3 curl naturally, after passing through heating wire 4 again and adding HEAT SETTING, and the fiber that just can obtain curling from filament mouth 6.
