Abstract
The invention discloses a method for producing novel fibers. The method comprises the following steps of: A, selecting single resin or a resin mixture for producing the fibers; B, mixing the single resin or the mixed resin uniformly in a mixing mill and heating until the mixture is in the melting state to obtain molten mass, allowing the molten mass to pass through a conduit and pressurizing the pressure in the conduit, blasting air into the conduit by using an air compressor, and ejecting the molten mass by using a nozzle under the action of a centrifugal machine; C, when the molten mass is ejected, blasting the air into the nozzle by using a high-speed blast blower, wherein the blast volume is between 10 and 120 m<3>/minute, and the blast pressure is between 0.1 and 1 kgf/cm<2>; and D, throwing the fibers formed by the molten mass under the action of the centrifugal machine out, and dragging the fibers under the blasting action for breaking to obtain fiber products. The fibers prepared by the method have good quality, long service life, and low production cost.
Description
Technical field
The present invention relates to a kind of production method of novel chopped fibre dimension.
Background technology
At present, at environmental protection, medical treatment, electronic applications, usually use goods such as cloth, felt, paper.These goods all are to be formed by fiber production.The production method of these fibers generally all adopts and uses mandatory stretching of wire drawing machine or spinnerets high pressure spray silk to form under molten condition at present.
With the polyphenylene sulfide fibre is example, application number is 200910216378.4 Chinese patent, a kind of method of polyphenylene sulfide meltblown fiber products is disclosed, the steps include: that resin premixed processing, double screw extruder fusion, granulation, section melt extrude spray silk, fixed length chopping, obtain polyphenylene sulfide fibre at last.Application number is 200510022439.5 Chinese patent, a kind of polyphenyl thioether spinning technology is disclosed, the steps include: resin pre-treatment, screw extruder fusion, forced filtration, melt metering pump metering, spinneret component spray silk, strand cooling, coiling doff, obtain polyphenylene sulfide fibre.
There are following shortcomings in the production method of present fiber well-known to those skilled in the art:
The one, during the production of short fiber, make long filament earlier, be cut into short fiber again, there is secondary operations, technological process is long;
The 2nd, the equipment investment of wire drawing machine or spray silk system complete equipments is higher, and the control difficulty is big, operation easier is big, maintenance cost is higher, so operating cost is also higher;
The 3rd, the fiber of gained is owing to force in process that stretches and the process of forcing the spray silk, fibrous inside can exist strand that does not trail in a large number and the strand of having been broken simultaneously, strand that does not trail and the strand quantity of having been broken are many more, just big more to fiber stretch-resistance and flexible destruction, and fiber stretch-resistance and pliability are to judge the basic index of fiber quality quality.Address the above problem and to find a kind of new production method to come shortened process, reduce equipment investment, reduce operating cost, improve fiber quality.
Summary of the invention
Goal of the invention of the present invention is: at the problem of above-mentioned existence, provide that a kind of production procedure is short, equipment investment is little, operating cost is low, the production method of the measured fiber of matter.The technical solution used in the present invention is such: a kind of production method of tencel may further comprise the steps successively:
A, take single resin or resin compound in producd fibers;
B, above-mentioned single resin or hybrid resin are evenly mixed in airtight mixing roll and heating reaches molten condition, obtain molten mass, to described mixing roll air blast, molten mass in the mixing roll flows to nozzle through conduit under blast pressure, described nozzle places on the centrifuge inwall, under the centrifuge centrifugal action, above-mentioned melt sprays by nozzle;
During the ejection of C, above-mentioned molten mass, with air blast with nozzle center's point be the air blast central point to the molten mass air blast, blow rate required 10-120m
3/ min, blast pressure 0.1-1kgf/cm
2
D, molten mass act as fiber through centrifuge and dish out, and cooling, obtain fiber product.
As preferably: in the B step, control said nozzle exit molten mass is 0.5-5kgf/cm to the pressure of nozzle inner walls
2
As preferably: in the B step, establish the distance at r=centrifuge rotating shaft center and centrifuge tube center, centrifuge rcf obeys: rcf=1.119 * 10
-5* r * (rpm) * (rpm), wherein: rmp=2000-4000, r=50-150mm.
As preferably: in the B step, described nozzle is that triangle, X-shaped, Y shape, pentalpha or ginkgo are leaf.
As preferably: in the C step, the air blast direction is around the air blast of nozzle center's point, and the plane that forms in the nozzle opening place is done and moved up and down.
As further preferred: when the plane that the air blast direction forms in the nozzle opening place was done and moved up and down, the scope that wind direction moves was and 0-30 ° of nozzle plane below 0-60 ° of nozzle plane top.
As further preferred: rate travel is 5-30mm/min.
As further preferred: during around the nozzle air blast, the mobile of wind direction is at random.Moving at random of wind direction is beneficial to and forms the high-quality fiber that nature curls.
Essence of the present invention is: that adopts the centrifugal force of centrifuge and wind-force makes a concerted effort to finish traction to resin melt, obtains the length uniform fibers simultaneously.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows:
The one, with centrifugal force and wind-force make a concerted effort to finish traction to resin melt, this traction should be different from enforceable stretching and spray silk.This traction has been played a combing effect to the molecular resin chain, the abundant stretching, extension of the strand that is highly advantageous to; The wide-spread while of molecular resin chain has also just reduced the molecule chain break.Thereby quality of fiber is greatly improved.
The 2nd, making a concerted effort to finish resin melt traction become fiber with centrifugal force and wind-force, along with after the stretching, extension of fiber reaches pulling force between strand and the strand and can not overcome tractive force, then fibrous fracture becomes staple fibre, because under the certain condition of, centrifugal force certain and wind-force at resin raw material, the length of fibrous fracture is certain, and therefore, this method has overcome makes long filament earlier, be cut into the problem of short fiber again, shortened technology.
The 3rd, the equipment investment of centrifuge, air blast is little, operating cost is low, easy operating, be easy to control, be easy to safeguard remarkable in economical benefits.
