Abstract
The invention provides spinning production technology for chinlon 6 functional fiber. The spinning production technology comprises the following steps: functional master batch is dried under the low temperature between 35 DEG C to 40 DEG C so that moisture content is reduced below 1000ppm; chinlon 6 slices and the dried functional master batch are respectively weighed, the chinlon 6 and the functional master batch are respectively placed in a mixing stirring barrel to be stirred evenly, and therefore a mixed raw material is formed; rotation speed of the mixing stirring barrel is 55 to 65 turns per minute and stirring time is 8 to 10 seconds; the mixed raw material is poured to a screw extruder to fuse so that a fused body is formed; and finally the fused body is pumped by a metering pump and delivered to a spinning component for spinning. According to the spinning production technology for the chinlon 6 functional fiber, the functional master batch is prevented from being oxidized, probability of occurrence of silk fluttering and silk head breaking is reduced, production efficiency is improved, and finished silk quality is improved.
Description
[technical field]
The present invention relates to the spinning field, particularly a kind of spinning production technology of polyamide fibre 6 functional fiber silks.
[background technology]
Functional fiber is synthetic fiber modified to routine, overcomes a fibrid of its intrinsic shortcoming; Or, give its additional function by the modified method of chemistry and physics at the performance that natural fabric and chemical fibre did not have originally, make a fibrid that is more suitable for human comfortable and easy to wear and decorative applications etc.
The functional fiber classification by use has following classification: 1, einnehmen function fiber, lead as nice and cool, high moisture absorption, height wet, highly shrink, fungi-proofing, insect protected, non-ironing, softness etc.; 2, decorate and to use functional fibre, as fire-retardant, variable color, noctilucence, fragrance, antifouling, self-cleaning etc.; 3, industry functional fibre is as high-strength, Gao Mo, conduction, absorption, separation, ageing-resistant, ion-exchange, biocompatible etc.
The production technology of existing capability fiber, because raw material master batch moisture height, the functional fiber of producing an end breakage rate height that wafts must stop in case the broken end production line occurs, handles, and makes percent defective uprise, and also influences production efficiency simultaneously greatly; The drying of existing master batch is generally taked the high temperature drying method, and high temperature drying makes that easily master batch is oxidized, causes finished product rotten; therefore generally take nitrogen protection to prevent oxidation; so just make that operation complicates, and the equipment of high temperature drying is had relatively high expectations, improved production cost greatly.
In addition, master batch only just mixes during fusion in screw extruder with section, because both viscosity height, mobile poor during fusion, so the mixing of the two is even inadequately, causes the quality decline of finished silk.
[summary of the invention]
The technical problem to be solved in the present invention, be to provide a kind of spinning production technology of polyamide fibre 6 functional fiber silks, can prevent the oxidation of functional master batch, reduce the waft probability of happening of silk broken end of spinning, enhance productivity, and can improve the quality of finished silk.
The present invention is achieved in that
A kind of production technology of polyamide fibre 6 functional fiber silks, described production technology may further comprise the steps:
Step 10, functional master batch is dry down 35 ℃～40 ℃ of low temperature is reduced to below the 1000ppm moisture;
Step 20, respectively chinlon 6 section and dried functional master batch are carried out weighing, all place then and mix mixing drum and stir, form mixed material; The rotating speed of described mixing mixing drum is 55-65 commentaries on classics/min, and mixing time is 8-10s;
Step 30, mixed material poured into carry out fusion in the screw extruder, form melt;
Step 40, by measuring pump melt is pumped to and carry out spinning on the filament spinning component at last.
Further, the mass ratio of described chinlon 6 section and dried functional master batch is 80～99:1～20.
Further, in the described step 30, the extruder temperature of described screw extruder is 230～300 ℃.
Further, pressure is 5～6MPa behind the described measuring pump, and the spinning speed of filament spinning component is 5000～5400m/min.
The present invention has following advantage:
The low temperature drying operation that is provided with, promptly under 35 ℃～40 ℃, functional master batch is carried out drying, can either prevent the oxidation of functional master batch, can also reduce the moisture of functional master batch, reduce the waft probability of happening of silk broken end of spinning, reduced the number of times that stops and the generation of waste product, improved production efficiency greatly and reduce production costs; After load weighted section and functional master batch mixed, enter the screw extruder fusion of advancing again, guaranteed the uniformity of section and functional master batch after the fusion, the feasible finished silk quality of making improves greatly.
