Abstract
The invention relates to a nylon filament yarn for a deep sea special fishing net, in particular to a black high-strength nylon filament yarn formed through melt blending and spinning and a production method thereof, and belongs to the field of textile manufacture. The nylon filament yarn is formed by performing melt blending and spinning on the following components in parts by weight: 80 to 180 parts of nylon resin, 0.5 to 3.0 parts of high color black with surface activity, and 0.1 to 2.0 parts of a modified EBS dispersant, wherein the nylon resin adopts resin 6 or resin 66, with the relative viscosity of 2.7 to 3.6. According to the nylon filament yarn, a melt blending method is adopted, black pigment is added into the interior of fiber, moreover, the material adopts the nylon resin with the high relative viscosity. Therefore, an obtained filament yarn product has the advantages of high breaking strength, high blackness, uniform color and no fastness.
Description
Technical field
The present invention relates to the Black high-strength Tynex and its production method of a kind of deep sea special type fishing net Tynex, especially melt blending spinning.Belong to weaving manufacture field.
Technical background
At present, general in deep sea special type fishing industry all using special netting gear is manufactured with soft black synthetic fibers.This nylon net long filament uses the nylon resin spinning of low relative viscosity, and fracture strength is not high.In addition, black necessary to long filament, uses dyeing and finishing technology after spinning, netting gear blackness is not high, and color uniformity not enough, is gradually faded in use, and certain pollution can be caused to ocean.Therefore, the sector urgently expects have a kind of technology that can make up above-mentioned deficiency to come out.
The content of the invention
In order to solve above-mentioned technological deficiency, the present invention provides a kind of deep sea special type fishing net Tynex, especially the Black high-strength Tynex and its production method of melt blending spinning.The long filament has fracture strength high, and blackness is high, and color is uniform, will never fade advantage.Present invention employs following technical scheme：
1. count by weight first and be obtained by spinning after following components blended melting：80~180 parts of nylon resin；0.5~3.0 part of the high-carbon black pigment of surface-active；Modified EBS dispersants 0.l~2.0 part；Wherein, described nylon resin is nylon 6 or nylon66 fiber, and relative viscosity is 2.7~3.6.
Above-mentioned Tynex is counted be obtained by spinning after following components blended melting by weight：90~120 parts of nylon resin；0.8~1.5 part of the high-carbon black pigment of surface-active；Modified 0.3~1.0 part of EBS dispersants.
Above-mentioned Tynex is counted be obtained by spinning after following components blended melting by weight：100~110 parts of nylon resin；0.9~1.2 part of the high-carbon black pigment of surface-active；Modified 0.3~0.8 part of EBS dispersants.
The relative viscosity of above-mentioned nylon resin is 3.0~3.6.
Above-mentioned Tynex is multifilament of the Denier range in 210~3360 daniers.
2. production method comprises the following steps：Step is 1. by described nylon resin, the high-carbon black pigment of surface-active and modified EBS dispersants according to 90~150：30~60：10~30 weight is than adding high-speed mixer mixing；Parallel double-screw is added after mixing carries out extruding pelletization, and the black nylon Masterbatch vacuum drying for having manufactured is stand-by；2. nylon resin section and dried black nylon Masterbatch are proportionally added in bipyramid spiral agitator step, after stirring 0.5~2 hour, are sent to screw extruder melting；The temperature setting of screw extruder is 290~298 DEG C, and head pressure is set as 10~15Mpa, 290~295 DEG C of condition of spinning manifold temperature, spinning measuring revolution speed 15~19RPM spinnerets；Step 3. tow at 15~20 DEG C, shaping is quenched in the air of relative humidity 75~85%, then by two-stage totally 4.0~5.5 times of drawing and setting at 190~200 DEG C, again after bleed pressure is 0.4~0. 8Mpa compressed air network devices, finished product long filament was with the speed coiling and molding of 2000~3000m/ minutes.
The temperature setting of above-mentioned step 1. middle twin-screw is followed successively by 80 DEG C, 240 DEG C, 240 DEG C, 240 DEG C, 240 DEG C, 230 DEG C, 230 DEG C from front to back.1. vacuum drying temperature is 90~120 DEG C to step, and overbottom pressure is less than 1Kpa.
Black pigment is added to the inside of fiber using the method for melt blending for the present invention, while nylon resin of the raw material using relative viscosity high, gained continuous yarn product has fracture strength high, and blackness is high, and color is uniform, will never fade advantage.
Specific embodiment
Embodiment：
By nylon resin, the high-carbon black pigment of surface-active, modified EBS dispersants according to 100：47：20（Weight ratio）Add high-speed mixer mixing.The high-carbon black pigment of surface-active selects QCHT8 high-carbon black pigment pigment, the EBS dispersant models that are modified TAS-2A.Parallel double-screw is added after mixing carries out extruding pelletization, and the temperature setting of twin-screw is followed successively by from front to back：80℃、240℃、240℃、240℃、240℃、230℃、230℃.The black nylon Masterbatch for having manufactured is in 100 DEG C of temperature, and overbottom pressure is stand-by less than vacuum drying under conditions of IKpa 4 hours.
