Abstract
The invention relates to a production process for black nylon stretch yarns. The production process comprises the steps of proportional mixing of nylon chips and black master batches in a master batch mixer, melting in a screw extruder, metering with a metering pump, spinning with a spinning component, cross air blowing cooling, bundling and oiling, packaging, balancing, and texturing, wherein 4 to 10 weight percent of black master batches are added; the temperature of the extruder is 250 to 280 DEG C; the temperature of a spinning box body is 250 to 270 DEG C. The production process has the beneficial effects that differences between the relative viscosity, melting point and the like of the black master batches and those of the spinning chips are little, so that a melt is substantially stable, the black master batches can be uniformly mixed with the melt, the problems of floating yarns, yarn waste, looping yarns and the like during spinning are reduced, and produced black nylon stretch yarn products are deep black; the spinning process is greatly different from the conventional process, and the temperature of each area of the extruder is set to be 250 to 280 DEG C, so that carbon black in the black master batches can be uniformly dispersed in the melt, the melt is endowed with higher flowability, and the produced black yarns are uniform in color.
Description
Technical field
The present invention relates to a kind of production technology of polyamide fibre black elastic filament.
Background technology
Along with the raising of environmental requirement, the dye-works of a lot of highly energy-consuming high pollution in polyamide fibre downstream is closed gradually.And nylon silk directly with the addition of Masterbatch in production process, thus produce outstanding silk, downstream client in use just can directly use, and need not dye again, eliminates dyeing and finishing link, not only economize energy but also meet environmental requirement.Therefore, nylon silk is more and more subject to the favor in market, and each polyamide fibre enterprise also starts to develop nylon silk.
Polyamide fibre black elastic filament is one of the most frequently used look silk, existing portioned product emerges in the market, but the polyamide fibre black elastic filament blackness produced in prior art is of low quality, in can only being used for, low-end market, wherein namely one of technological difficulties are that the addition of Masterbatch on the current technology cannot more than 3%, the interpolation of Masterbatch can bring very large difficulty to spinning, and Masterbatch relative viscosity, fusing point etc. all affect melt stability; And conventional production process generally adopts small screw extruder to measure Masterbatch, mix dissolving spinning with slices of caprone after Masterbatch being added to extruder, the uniformity of dispersion is undesirable.
Therefore, be necessary to propose effective technical scheme, solve the problem.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of production technology of polyamide fibre black elastic filament is provided.This technological operation is simple, and the polyamide fibre black elastic filament product blackness of production is dark, color is even, intensity is high, good springiness.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of production technology of polyamide fibre black elastic filament, and step is as follows:
1), slices of caprone mixes by weight percentage with black agglomerate;
2), by above-mentioned compound through extruder heating and melting, extrude;
3), by above-mentioned melt through measuring pump quantitatively, press-in filament spinning component, through spinnerets ejection, forms tow in spinning manifold;
4), by above-mentioned tow undertaken cooling, boundling oils, package, balance, add bullet, finally obtain polyamide fibre black elastic filament product;
Described black agglomerate adding proportion is 4-10%;
The temperature of spinning manifold is 250-270 degree Celsius.
Beneficial effect:
1) the present invention sets up master batch mixer on spinning threadling, Masterbatch and slices of caprone adopt weight metering, by metering and the mixing of master batch mixer, after mixing in proportion, enter screw extruder, melt spinning, and Masterbatch relative viscosity of the present invention, fusing point etc. are more or less the same with spinning chips, such melt is basicly stable, Masterbatch and melt mixed even, not easily produce when spinning the problems such as silk, lousiness, circle silk of wafing, the polyamide fibre black elastic filament product blackness of production is dark;
2) spinning technique of the present invention is very large with conventional variety difference, and extruder each district temperature is set as 250-280 degree Celsius, and make the carbon black in Masterbatch disperse in the melt uniformly, melt has good mobility, and the black silk color produced is even.
Detailed description of the invention
Be described principle of the present invention and feature below, example, only for explaining the present invention, is not intended to limit scope of the present invention.
The production technology of a kind of polyamide fibre black of the present invention elastic filament, brief description of the process is: slices of caprone and black agglomerate mix → enter screw extruder melting → measuring pump metering → filament spinning component spray silk → lateral blowing cooling → boundling in proportion by master batch mixer and oil → package → balance → add bullet → black elastic filament.
The concrete steps of production technology of the present invention are as follows:
1), slices of caprone mixes by weight percentage with black agglomerate;
2), by above-mentioned compound through extruder heating and melting, extrude;
3), by above-mentioned melt through measuring pump quantitatively, press-in filament spinning component, through spinnerets ejection, forms tow in spinning manifold; The temperature of spinning manifold be 250-270 degree Celsius (example 250 degrees Celsius, 260 degrees Celsius, 265 degrees Celsius, 270 degrees Celsius).
4), by above-mentioned tow undertaken cooling, boundling oils, package, balance, add bullet, finally obtain polyamide fibre black elastic filament product;
Described black agglomerate adding proportion is 4-10%; Carbon black precision in black agglomerate reaches nanoscale, after the abundant mixed melting of section, good dispersion is less on the impact of spinning spinnability.
Polyamide fibre black elastic filament product blackness of the present invention is even, and fracture strength is high, and for 70D/24F, fracture strength reaches more than 4.1cN/dtex, and elongation at break is 20-40%, and elasticity is high, and the rate mean value of crispaturaing reaches 54%, and comparatively market product exceeds 1 times.
COLOR FASTNESS of the present invention is high, and COLOR FASTNESS is greater than 4.5 grades by European market standard testing.
Wherein in POY production, spinning speed controls at 4200-4500 m/min, has good spinnability, breaks end less.Due to the characteristic of raw material polyamide fibre of the present invention, molecular balance is moved to the left, and in melt, monomer is separated out, and can have a negative impact to spinning, and the present invention's spinning temperature of 250-270 degree Celsius in POY produces, good spinning effect can be obtained.、
POY balances 24 hours, carries out adding bullet.Its technique is as follows:
DTY speed of production 500-700 m/min, heater temperature 160-185 degree Celsius, D/Y than 1.8-2.3, drafting multiple DR 1.2-1.4.
The present invention can summarize with other the concrete form without prejudice to spirit of the present invention or principal character.Therefore, no matter from which point, above-mentioned embodiment of the present invention all can only be thought explanation of the present invention and can not limit the present invention, claims indicate scope of the present invention, and scope of the present invention is not pointed out in above-mentioned explanation, therefore, any change in the implication suitable with claims of the present invention and scope, all should think to be included in the scope of claims.
