Abstract
The invention discloses a production process of colored vortex spun yarn, which at least comprises one of white fiber, yellow fiber, magenta fiber, cyan fiber and black fiber; the yellow fibers, the magenta fibers, the cyan fibers and the black fibers are all dope-dyed fibers; the invention relates to a production process of colored vortex spun yarn, which adopts three primary colors stock solution to color fibers, and can accurately match colors by a strip mixing mode when the content of the colored fibers is small.
Description
Technical Field
The invention relates to the technical field of vortex spinning, in particular to a production process of colored vortex spun yarn.
Background
The colored spun yarn is formed by selectively mixing colored fibers (dyed fibers or stoste-colored fibers) and then spinning the colored fibers into colored yarn with certain color. The colored yarn is used for yarn weaving, and color distribution is formed on the fabric through color blending, such as strip lattice fabric, jacquard fabric and other cloth cover effects.
The traditional color spinning process has two types, one is that the sliver with different colors is made by pre-spinning color mixing, and then the color-mixed yarn is formed by fine yarn drafting and twisting; in the spinning stage, two kinds of roving with different colors are fed separately via the middle and back rollers of the drafting mechanism, and one of the roving is drafting unevenly and then combined and twisted to form slub segment color yarn. Such a spun-dyed yarn cannot be subjected to full-color spinning because mixing in an arbitrary ratio cannot be performed to conveniently perform toning, thereby limiting the wide use of the spun-dyed yarn in textiles.
When the mixing is performed by drawing, if the ratio of the colored fibers is below 1/8, it is not easy to grasp by the drawing mixing, especially when the color matching is performed by using the pair of three primary color fibers. When the content of the colored fiber is small, how to blend the proper color by adopting a strip mixing mode becomes a difficult problem.

Detailed Description
The invention is further described with reference to the following figures and specific examples.
Example one
This embodiment will be described in detail with reference to fig. 1. The production process of the color vortex spun yarn according to the embodiment comprises at least one of white fibers, yellow fibers, magenta fibers, cyan fibers and black fibers; the yellow fibers, magenta fibers, cyan fibers and black fibers are all dope-dyed fibers. Specifically, the white fibers are polyester staple fibers, and the yellow fibers, the magenta fibers, the cyan fibers and the black fibers are all dope-dyed polyester fibers.
The production process of the color vortex spun yarn comprises the following process steps:
and S1, respectively manufacturing the white fibers, the yellow fibers, the magenta fibers, the cyan fibers and the black fibers into a white cotton sliver, a yellow cotton sliver, a magenta cotton sliver, a cyan cotton sliver and a black cotton sliver for standby, wherein the basis weight of each fiber cotton sliver is the same.
And S2, selecting a yellow cotton sliver, a magenta cotton sliver, a cyan cotton sliver, a black cotton sliver or a white cotton sliver according to the proportion of yellow fibers, magenta fibers, cyan fibers and black fibers in the colored fibers, and carrying out sliver mixing on a drawing frame to obtain the mixed cotton sliver.

And S3, carrying out sliver mixing on the mixed sliver obtained in the last step and a white sliver in a drawing frame according to the proportion of the colored fibers in the colored vortex spinning to obtain the mixed fiber semi-finished sliver. And then drawing and mixing the mixed cotton sliver prepared in the last step with 7 white cotton slivers, wherein the content of the colored fibers in the theoretical colored vortex spun yarn is 12.5 percent, and the content of each colored fiber is the same.
And S4, drawing and mixing the mixed fiber semi-finished slivers prepared in the previous step for 1-3 times again to obtain the mixed fiber semi-finished slivers.
S5, preparing the mixed fiber drawn sliver prepared in the previous step into color vortex spun yarn by adopting a vortex spinning process.
The prepared colored vortex spun yarn was tested to have a colored fiber content of 12.3%, which was essentially the same as theoretical.
Example two
The present embodiment will be described in detail with reference to fig. 2 and 3. The production process of the color vortex spun yarn according to the embodiment comprises at least one of white fibers, yellow fibers, magenta fibers, cyan fibers and black fibers; the yellow fibers, magenta fibers, cyan fibers and black fibers are all dope-colored fibers. Specifically, the white fibers are made of stretch yarn and polyester staple fibers according to the weight ratio of 1: 1 and mixing. Yellow fibers, magenta fibers, cyan fibers and black fibers are all dope-dyed polyester fibers.
The difference from the first embodiment is that the white sliver is a white mixed fiber sliver containing the shu-elastic fiber.
The preparation process of the white mixed fiber cotton sliver comprises an opening and picking process and a carding process;
in the opening and picking procedure, the first blowing is carried out on the stretch yarn fiber and the fiber to be blended according to the blending ratio; and packaging the mixed fiber grabbed by the first blowing, and performing second blowing.
The two-time blowing process is adopted because the elastic yarn has curly texture and is difficult to comb. During carding, the mixing uniformity with other fibers to be mixed is poor. The process of twice blowing is adopted, so that the comfortable elastic yarns and other equal-mixed fibers are fully mixed before carding, and the problem of poor fiber mixing uniformity caused by high carding difficulty is solved.
Specifically, in the opening and picking process, the Telitsler blowing-carding unit is used, and the process principle of 'more loosening, more carding, less beating, less damage and less dropping' is adopted. The bale plucker used in the first and second blowing is a disc type bale plucker. The main technological parameters are as follows: the beater speed of the bale plucker is 1200r/min, the walking speed is 15m/min, and the bale plucking depth is 2.5 mm. Specifically, in this embodiment, the stretch yarn and the polyester fiber are mixed, according to a ratio of 30: 70, or other natural or synthetic fibers such as cotton, acrylic, viscose, nylon, lyocell, modal, etc.
The carding machine TC10 equipment is adopted in the carding process. Other carding apparatus may also be selected. In the carding process, the main process parameters of the carding machine are as follows: cylinder speed 370r/min, licker-in speed 960r/min, sliver output speed 165m/min, cover plate speed 120mm/min, cover plate-to-cylinder spacing 30.5mm/1000, 27.9mm/1000, 25.4mm/1000, cylinder-to-doffer spacing 28mm/1000, and sliver ration 5 g/m.
The density of the needle teeth on the metal card clothing used by the carding machine is 450- 2 The working angle alpha on the metallic card clothing is 50-70 deg.. Specifically, in this embodiment, the pin density is 500Points/inch2, and the working angle is 60 °.
Further, as shown in fig. 2 and 3, the working angle α of the teeth is increased and the density of the teeth is decreased, so that the elastic yarn can be peeled from the teeth 2 easily. The total height h of the base part 1 and the needle teeth 2 is 4.5mm, and the tooth depth h of the needle teeth 2 is 2.50 mm. At the moment, the tooth tip hardness is more than or equal to 780HV, the tooth tip width a is 0.15mm, and the needle tooth thickness b is 0.17 mm.
And further, the needle 2 includes a first needle tooth 21, a second needle tooth 22 and a third needle tooth 23 arranged in this order in the present embodiment. The working surface and the back surface of the first pin tooth 21 are both linear; the working surface of the second needle tooth 22 is of a concave arc structure, and the back surface of the second needle tooth is of a convex arc structure; the third tooth 22 and the working and back faces each present a convex arcuate configuration.
On the premise of enlarging the working angle of the pin teeth 2, if the traditional pin tooth shape is adopted, the carding effect of the elastic yarn is not good. In order to completely and uniformly comb the elastic yarn, the effect of gathering the elastic yarn is avoided. The three types of card clothing with the shapes of the card teeth are adopted to comb the elastic yarn.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
