Abstract
The invention discloses a direct spinning method which is suitable for chemical fibers. The method comprises the following steps of: heating fiber slices obtained by drying a high polymer melt in a screw for melting, extruding and conveying the fiber slices into each spinning position of a spinning box body, metering accurately by a metering pump, filtering, and spraying the fiber slices from small holes of a spinneret plate; and cooling the sprayed melt thin flow by cooling air flow, and solidifying to form silk. The direct spinning method has the advantages of novel concept and skillful design; and by improving the condition and process of the conventional direct spinning method, the defects in the prior art are overcome, the yield is improved, and the cost is reduced, so that the aim of realizing the direct spinning method is fulfilled.
Description
Technical field
The present invention relates to chemical material technical field, specifically, specially refer to a kind of direct fabrics method that is applicable to chemical fibre.
Background technology
Chemical fibre is the general designation that raw material, process chemistry or physical method are processed the fiber that makes with polymer substance natural or that manually synthesize.Different because of used macromolecular compound source, can be divided into artificial fibre and the synthetic fiber take the synthetic high polymer material as raw material take natural high molecular substance as raw material, be called for short chemical fibre.
Nineteen forty-one, the J.R. Weinfield of Britain and J.T. Dixon are at first succeeded in developing polyester fiber, called after terylene (Terylene) take terephthalic acid (TPA) and ethylene glycol as raw material in the laboratory.But the nineteen fifty-three commodity produced in USA polyester fiber that reaches synthetic fibre (Dacron) by name.Polyester fiber is developed rapidly in countries in the world subsequently.The nineteen sixty world wide production of polyester fiber surpasses polyacrylonitrile fibre, surpasses again polyamide fiber in 1972, becomes the first kind of synthetic fiber.
Summary of the invention
The object of the present invention is to provide a kind of direct fabrics method that is applicable to chemical fibre, by condition and technique in the existing direct fabrics method are improved, overcome the deficiency in the conventional art, improved output, reduce cost, thereby realized purpose of the present invention.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of direct fabrics method that is applicable to chemical fibre, it comprises the steps:
With the dried fibre section of high polymer molten heating and melting in screw rod, each spinning part of spinning manifold is sent in extruding, after the measuring pump accurate measurement and filtering, sprays from the aperture of spinnerets; The melt thread of ejection, the air-flow cooled and solidified that is cooled becomes strand.
In one embodiment of the invention, the diameter range of described spinneret orifice is 0.25～0.30 millimeter.
In one embodiment of the invention, the temperature range of described cooling blast is 10 ℃-20 ℃.
Beneficial effect of the present invention is: novel, design ingeniously, and by condition and technique in the existing direct fabrics method are improved, overcome the deficiency in the conventional art, improved output, reduce cost, thereby realized purpose of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
A kind of direct fabrics method that is applicable to chemical fibre of the present invention, it comprises the steps:
1) with the dried fibre section of high polymer molten heating and melting in screw rod;
2) fibre section after step 1) is processed is pushed each spinning part of sending into spinning manifold, after the measuring pump accurate measurement and filtering, from the aperture of spinnerets, spray;
3) the melt thread of ejection, the air-flow cooled and solidified that is cooled becomes strand.
In one embodiment of the invention, in order to reach better effect, the diameter range of described spinneret orifice is 0.25～0.30 millimeter.
Especially it is pointed out that the time that needs in order to save abundant cooling lock, the temperature range of described cooling blast is 10 ℃-20 ℃.
The present invention is novel, designs ingeniously, by condition and technique in the existing direct fabrics method are improved, has overcome the deficiency in the conventional art, has improved output, has reduced cost, thereby has realized purpose of the present invention.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
