Detailed Description
In order to explain the technical content, the objects and the effects of the present invention in detail, the following description will be given with reference to the embodiments.
The most key concept of the invention is as follows: the equipment is not modified and debugged, and the chinlon 6 pre-oriented yarn is subjected to the working procedures of heating, cooling, false twisting, drafting, oiling and winding by adjusting the texturing process to prepare the chinlon 6 filament yarn with the bamboo joint effect.
The invention provides a production method of chinlon 6 filament with bamboo joint effect, which comprises the following steps:
sequentially passing the polyamide 6 pre-oriented yarn through a raw yarn frame, a yarn cutter, a first roller and a yarn guide, a hot box, a cooling plate, a false twister, a second roller, a third roller, a yarn detector, an oiling device and a winding device to obtain the polyamide 6 filament with the bamboo joint effect;
the temperature of the hot box is 195-210 ℃;
the false twisting speed ratio of the false twister is 1.80-2.60;
the speed of the second roller is 500-600 m/s;
the speed ratio of the second roller to the first roller is 1.05-1.20, namely the drafting ratio is 1.05-1.20.
The invention also provides the nylon-6 filament with the bamboo joint effect, which is prepared by the production method.
From the above description, the beneficial effects of the present invention are: the production method of the chinlon 6 filament with the bamboo joint effect provided by the invention does not need equipment transformation and debugging, and only adjusts the elasticizing process, after the chinlon 6 pre-oriented yarn with uniform thickness produced by high-speed spinning is subjected to the working procedures of heating, cooling, false twisting, drafting, oiling and winding, the nylon 6 filament with the bamboo joint effect can be obtained, the filament bundle does not pass through the twist stop by replacing the twist stop device with the filament guide, the twist is transmitted to the free zone to cause tension fluctuation, the obtained nylon 6 stretch yarn has the appearance of uneven thickness, meanwhile, the filament bundle of the method does not pass through the interlacer after passing through the second roller, the nylon 6 filament with the slub effect is not added with a network, so that the phenomenon that the appearance of uneven thickness of the nylon 6 filament with the slub effect is damaged and the thickness distribution effect of the nylon 6 filament with the slub effect is influenced is avoided;
the chinlon 6 filament with the slub effect prepared by the method has different coarse and fine distributions, and the slub length, the slub multiple and the slub distance are changeable and controllable; the fabric woven by the chinlon 6 filament with the bamboo joint effect has strong concave-convex stereoscopic impression, obvious dyeing difference and unique and various styles.
Further, the temperature of the hot box is 200-210 ℃.
From the above description, the temperature of the hot box is adjusted to enable the nylon 6 pre-oriented yarn to be fully stretched and deformed in the subsequent process, so that the filament bundle becomes curled and fluffy to a certain extent, and the obtained nylon 6 filament with the slub effect has high slub multiple and obvious slub effect. The temperature of the hot box is increased as much as possible, so that the nylon 6 pre-oriented yarns are close to a molten state, partial yarns are bonded and form tight-point yarns, the detailed sections cannot be untwisted, the slub effect is obvious, and the over-high temperature of the hot box can be avoided at 200 ℃ and 210 ℃, so that the nylon 6 pre-oriented yarns are bonded and form long-section stiff yarns, and the distribution effect of the thickness sections of the nylon 6 filaments with the slub effect is influenced; and the phenomenon that the temperature of the hot box is too low so that the nylon 6 elastic yarn is drafted to generate broken yarns when being insufficiently heated can also be avoided.
Further, the false twist speed ratio of the false twister is 2.40-2.60.
According to the description, the thick section yarns of the nylon 6 pre-oriented yarns are fluffy through the adjustment of the false twist speed ratio, the handfeel is good, and the bamboo joint length, the bamboo joint multiple and the bamboo joint distance are variable and controllable; the false twisting speed ratio is prevented from being too high, the possibility that the tows are scratched by a friction disc is increased, and the fibers are excessively worn to cause broken ends or broken filaments; and the problems that the false twisting speed ratio is too low, tows cannot be twisted fully, thick section filaments are not fluffy enough, the fiber slub multiple is too low, and the distribution effect of the thick and thin sections of the nylon 6 filament with the slub effect is influenced are also avoided.
Further, the false twister is a friction spindle set type false twister, and any spindle set combination of 1-5-2, 1-6-2, 1-7-2 or 1-3-1-3-1 is adopted.
Further, the false twister is a friction spindle group type false twister, the output sheet of the false twister is a light sheet, and the number of the light sheets is 2.
As can be seen from the above description, the false twister adopts a friction spindle set type false twister, the leading-in piece is a polished piece, the working piece is a friction piece, the output piece is a polished piece, and a polished piece is added, so that thick and thin sections obtained after heating, cooling and false twisting of the polyamide 6 pre-oriented yarns are output without untwisting, the strand silk of the thick section is fluffy, the cohesion of the thin section is good, the distribution of the thick section and the thin section is clear, and the bamboo joint effect is obvious.
Further, the speed of the second roller is 500-550 m/s.
According to the description, the speed of the second roller is reduced, so that the bamboo joint effect can be effectively controlled after the tows are heated, cooled, false-twisted and stretched, the obtained nylon 6 filament with the bamboo joint effect has the appearance of uneven thickness, the thick sections and the thin sections are clearly distributed, and the bamboo joint length, the bamboo joint multiple and the bamboo joint distance are changeable and controllable.
Further, the speed ratio of the second roller to the first roller is 1.05-1.15, namely the drafting ratio is 1.05-1.15.
According to the description, the speed ratio of the second roller to the first roller is adjusted, namely the draft ratio is reduced, so that the yarn is under the condition of insufficient stretching, the tension fluctuation is caused, the thin sections are generated, the thick sections and the thin sections are clearly distributed, and the bamboo joint effect is obvious; the problem that the drawing ratio is too high to influence the distribution effect of the thickness knots of the chinlon 6 filament with the bamboo joint effect is avoided.
Furthermore, the length of the slub of the chinlon 6 filament with the slub effect is 0.5-3.0cm, the slub multiple is one or more of 1.5-2.5:1, and the distance between slubs is 0.5-5.0 cm.
According to the description, the slub length, the slub multiple and the slub distance of the nylon 6 filament with the slub effect are adjusted, so that the nylon 6 filament with the slub effect has the appearance of uneven thickness, the slub length, the slub multiple and the slub distance are changeable and controllable, fabrics woven by the nylon 6 filament with the slub effect and with different thickness distribution rules present different concave-convex stereoscopic impression and dyeing difference, and the styles are unique and diverse.
