The method has the advantages of simple process, convenient operation and low cost, and is suitable for large-scale production.
Description
Technical field
The present invention relates to a kind of processing method of nylon monofilament, belong to the chemical fibre production technical field.
Background technology
Polyamide fibre is the synthetic fiber kind of carrying out suitability for industrialized production the earliest, belongs to the fatty polyamide fiber.The principal item of polyamide fibre has polyamide fibre 6 and polyamide fibre 66.The polyamide fibre performance is good, output is high, and purposes is wide, is the main synthetic fiber kind that is only second to terylene.
Polyamide fibre also has a spot of polyamide fibre staple fibre in addition based on long filament.Chinlon filament is mainly used in the manufacturing high-tenacity fibre, for producing socks, underwear, sweater etc.The polyamide fibre staple fibre mainly is to close fine blending with sticking fine, cotton, hair and other, as clothing cloth.Polyamide fibre also can be industrial as tire cord, parachute, fishing net, rope, conveyer belt etc.
The hygroscopicity of nylon fabric belongs to better kind in synthetic fabrics, therefore more comfortable and easy to wear than terylene clothes with the clothes of polyamide fibre making, and good moth-resistant, decay resistance are arranged.
Polyamide fibre is all good inadequately because of its heat-resisting light resistance, so ironing temperature should be controlled at below 140 ℃.In wearing use, must note the condition of washing, maintenance, in order to avoid the damage fabric.
Nylon fabric belongs to light-duty fabric, only lists in synthetic fabrics after polypropylene fibre, the acrylic fabric, therefore, is fit to make anorak, water clothes etc.
The nylon fibre lining can be divided into purely spin, blending and intertexture three major types, comprise many kinds in each big class.
1, the polyamide fibre PURE YARN FABRIC is the various fabrics that raw material is made into the POLYAMIDE YARNS, as polyamide fibre taffeta, polyamide fibre crape etc.Because of being made into,, also there are fabric easily wrinkle and the difficult shortcoming of recovering so smooth, strong durable, the moderate characteristics of feel are arranged with chinlon filament.The polyamide fibre taffeta is used for makeing sporty, down jackets or raincoat cloth more, and the polyamide fibre crape then is fit to make clothing skirt in summer, reversible jacket etc.
2, polyamide fibre blending and intertexture adopt chinlon filament or staple fibre and other fiber to carry out blending or interweave and the fabric that obtains, have the characteristics and the strong point of every kind of fiber concurrently.As sticking/bright and beautiful gabardine, the polyamide fibre of employing 15% and 85% viscose blended resultant yarn make, and have through close to be twice than filling density, and the body quality is abundant, tough and tensile endurable characteristics, and shortcoming is a poor flexibility, easy wrinkle, wet strong decline, easily sagging when wearing.In addition, also having sticking/bright and beautiful valetin, sticking/kinds such as brocade/hair fancy suiting, all is some linings commonly used.
Nylon monofilament is as an important component part of chinlon filament, and the means of production falls behind all the time, and conventional production method is to adopt veneer single hole or the few hole (hole count≤8) of veneer to produce monofilament, and few hole polyamide multifilament also is taken as monofilament and uses on market.And developing rapidly along with industrial or agricultural and fish production, physical and mechanical properties to nylon monofilament has proposed new requirement, particularly in the fishing net manufacturing, manufacturing process is changed into after the mechanical knitmesh by braiding, requirement to its TENSILE STRENGTH is just higher, and two conventional road draft process can't satisfy the specific (special) requirements of some aspect of monofilament.
Summary of the invention
The object of the present invention is to provide a kind of and existing production method that processing method than the nylon monofilament of big-difference is arranged, this method technology is simple, easy to operate, and cost is lower, is fit to large-scale production.
The technical scheme that the present invention takes comprises:
1, adopts section to spin production method and carry out spinning production.
2, in spinning process,, before drawing-off, carry out the branch silk and form monofilament from the multifilament process ring blowing cooling of spinnerets ejection.
3, concrete technological process is: nylon dried granules → melt extrude → measure → multi-holed jet spray silk → condensation water-bath → 1 fen silk → first order drawing roller → first order drawing-off hot bath → second level drawing roller → second level drawing-off hot bath → third level drawing roller → third level drawing-off hot bath → the 4th drawing roller → 2 fens silk → coiling of minute silk device of minute silk device.
As the preferred version of the technical program, the monofilament radical is between 1～18 from the multifilament of spinning head ejection.
As the preferred version of the technical program, the monofilament parallel arranged in multistage hot bath and drawing roller behind 1 fen silk of undue silk device is carried out drawing-off, and monofilament is 1～3mm at interval, divides once more thread through a undue silk device 2, is wound on the paper tube at last.
In the described technical scheme, multifilament and monofilament linear density≤150dtex.
In the described technical scheme, divide the silk device to select for use wear-resisting antistatic special ceramic material to be made.
In the described technical scheme, polyamide fibre can be any one of polyamide fibre 6 or polyamide fibre 66.
Beneficial effect of the present invention is embodied in:
1, can solve veneer single hole spinnerets and produce the problem that nylon monofilament yields poorly, enhance productivity to greatest extent, reduce production costs.
2, three grades of drawing-offs can better improve the strength and extension property of monofilament, and application range of products improves greatly.
3, this production method technology is simple, easy to operate, the suitable production in enormous quantities in enormous quantities.
The specific embodiment
Below by an embodiment the present invention is specifically told about.
Raw material is selected the nylon dried granules that contains an amount of clarifier: viscosity average molecular weigh 17000-17500 for use; Low-molecular material content 2.1%; Moisture 0.06%.
Capital equipment comprises: extruder, measuring pump, wire drawing machine (three hot water storgaes on the wire drawing machine), winding head (can adjust maximum package several 12 according to the quantity of once reeling), a branch silk device, miscellaneous equipment or device.
The specification of polyamide multifilament is 110dtex/10f; The specification of nylon monofilament is 10dtex/f, diameter 0.22-0.25mm.
Technological process by nylon dried granules → melt extrude → measure → multi-holed jet spray silk → condensation water-bath → 1 fen silk → first order drawing roller → first order drawing-off hot bath → second level drawing roller → second level drawing-off hot bath → third level drawing roller → third level drawing-off hot bath → the 4th drawing roller → minute 2 fens silk → coiling of silk device of minute silk device is produced, reasonably control the parameter of each operation, final production has gone out the nylon monofilament of acceptable quality, and the product physical index is as shown in the table:
| Project | Unit | Value |
| Filament diameter | mm | 0.21 |
| Line density | dtex | 10 |
| Tensile break strength | N/tex | 0.435 |
| Elongation at break | ％ | 30.4 |
