Background
The traditional AB yarn is spun yarn produced by drafting an A roving produced by one fiber and a B roving produced by another fiber, and generally, the fiber in the A roving and the fiber in the B roving have small difference in fiber component and blending proportion, because if the A, B roving has large component difference, uneven blending can be caused, and color grade can be generated. Along with the improvement of living standard of people, functional textiles are more and more popular with people, the market has higher and higher demand on small-proportion functional fiber blended fabrics, and especially the demand on special flashing functionality is higher. The traditional production technology can not meet the market requirements, especially can not meet the weaving requirements of the small-proportion functional fiber blended fabric, and meanwhile, the technical problem to be solved is also solved urgently how to improve the flashing effect of the small-proportion flashing fiber blended fabric.
Disclosure of Invention
The invention aims to solve the technical problem of the prior art, provides the glittering compact spinning elastic AB yarn and the production method thereof, solves the technical problem of spinning with an ultra-small blending ratio (less than 5 percent), and solves the problem of poor glittering effect of spinning with the ultra-small blending ratio of glittering fibers.
The technical scheme for solving the technical problems is as follows: the production method is characterized in that flash fibers, main material fibers and terylene are used as raw materials of A roving, the raw material of the A roving is subjected to blowing-carding-drawing-first, drawing-second and roving processes in sequence to produce the A roving, single-variety fibers are used as raw materials of B roving, the raw materials of the B roving are subjected to blowing-carding-drawing-first, drawing-second and roving processes in sequence to produce the B roving, and meanwhile, A, B two kinds of roving are subjected to spinning and spooling processes in sequence to form yarn.
Further, the raw material of the A roving adopts R/T/T light with the blending ratio of 80/10/10, main material fiber/terylene/flash fiber, the raw material of the B roving adopts 100% R, wherein R is the main material fiber, T is the terylene fiber, T light is the flash fiber, the main material fiber adopts rayon (namely viscose fiber), modal or tencel, and the flash fiber adopts the terylene flash fiber. In the process of producing the A roving, a falling object sensor and a CCD (charge coupled device) visual photoreceptor are respectively installed in each falling object area of the blowing-carding unit, and intelligent identification and control are carried out on the flash fibers in the falling objects, so that the blending difference of the flash fibers in the raw material of the A roving is controlled within +/-1.0%.
Furthermore, the glittering fiber in the raw material of the A roving adopts coarse denier fiber, and the main material fiber and the terylene adopt fine denier fiber.
Furthermore, the flash fiber in the A roving raw material adopts 2.78-3.89dtex coarse denier fiber, preferably 3.3dtex coarse denier fiber, and the main material fiber and the terylene adopt 1.3-1.67dtex fine denier fiber, preferably 1.3dtex fine denier fiber. The thick denier fibers are distributed on the outer layer and the fine denier fibers are distributed on the inner layer by utilizing the motion rule of the fibers with different finenesses in the spinning process, so that the thick denier flash fibers in the scheme can be distributed on the outer layer of the yarn as far as possible; under the premise that the use ratio of the flash fibers is not changed, the flash effect is increased, namely, the use ratio of the flash fibers is reduced and the raw material cost is reduced on the premise that the flash effect is ensured.
Further, the indexes of the cotton sliver in the blowing-carding-drawing process are as follows: dry basis weight is 17.0 g/5 m to 20.0 g/5 m, and strip discharging speed is 130 m/min; in the drawing step, the total draft multiple is 6.32-6.58 times, the back zone draft multiple is 1.75, the drawing speed is 320 m/min, and the total number of the drawn yarns is 6; in the drawing two working procedures, the total draft ratio is 7.82-8.04 times, the back zone draft ratio is 1.35, the drawing speed is 320 m/min, the number of drawn yarns is 7, and the fiber straightness of the drawn yarns is more than 95%. The A roving adopts the process design of the oversized back draft multiple of the parameters in the first drawing procedure and the second drawing procedure, so that hooked fibers are eliminated, the fiber straightness is improved, and the glittering effect of the yarn is improved.
Furthermore, the method for adjusting the dry basis weight of the A roving in the roving process achieves the required glittering blending ratio, and compared with the traditional method, the method has the advantages of convenience, simplicity, high efficiency and the like. Specifically, in the roving process, the dry weight of the A roving is 2.8 g/10 m-4.0 g/10 m, the dry weight of the B roving is 4.0 g/10 m, the twist factor is 79, and the glitter fiber can be controlled to be adjusted between 4% and 10%.
The blending ratio of the A roving is 80/10/10 in terms of R/T/T light, the B roving is 100% R, when the dry basis weight of A, B two rovings are completely equal, namely 4.0 g/10 m, the blending ratio of the outer fiber of the yarn is 90/5/5 in terms of R/T/T light; when the dry basis weight of the a roving is less than the dry basis weight of the B roving, as follows: the dry basis weight of the A roving is 2.8 g/10 m, the dry basis weight of the B roving is 4.0 g/10 m, the blending ratio R/T/T light of the coated fibers of the yarn is 92/4/4, and the glittering blending ratio is convenient to adjust by the method, so that the problems of large blending ratio difference and nonuniform glittering of the glittering fibers with ultra-small blending ratio (less than 5%) are solved.

The blowing-carding process is mainly used for increasing the cotton mixing effect, reducing the fiber damage and reducing the noil. The process method comprises the following steps: freely holding, beating instead of combing, properly enlarging the spacing between combing pieces in the carding area and reducing the relative speed between the combing pieces, and the main process configuration is as follows:
the drawing process adopts a method of 'tight-spacing, heavy-pressurization and optimized drafting process', raw materials form cotton slivers through a blowing-carding process, the fibers in the raw slivers are not in an ideal straightening state and are usually provided with front-end hooks (also called front hooks) and rear-end hooks (also called rear hooks), and the elimination of the fiber hooks is mainly eliminated by adopting reasonable process configuration in the drawing process. The drafting multiple of the drawing-back area is within 1.35, the drafting multiple of the drawing-back area is 1.75 times and is overlarge, the speed difference between the front fiber and the back fiber is larger in the drawing-back drafting area, the front hook of the back fiber can be eliminated in the relative movement process of the front fiber and the back fiber, and the back hook of the front fiber can be eliminated. Because the production process is continuous, the back fiber is changed into the front fiber in the fiber advancing process, so that the front and back hooks of the fiber in the sliver are eliminated, and the fiber straightness is over 95 percent. The method has the advantages that the fiber straightness is improved, the tight spacing and the heavy pressure are favorable for controlling the floating fibers, the evenness is improved, and the main process configuration is as follows:
