Description

Production method of spun viscose compact siro spinning yarn
Technical Field
The invention relates to the technical field of spinning, in particular to a production method for spinning viscose compact sirospun yarns.
Background
In order to overcome the defects of the traditional ring spinning yarn, a plurality of novel spinning technologies appear, which mainly comprise the reform technology of the ring spinning and the novel spinning technology, wherein the siro spinning technology is the novel spinning technology which is most widely applied and has the most economic benefit at present.
The compact siro spinning combines the characteristics of the siro spinning and the compact spinning with the resultant yarn, has very good evenness CV value, slubby and detail indexes, high single yarn strength, compact structure, good wear resistance, less hairiness, less harmful hairiness above 3mm, bright and clean folded yarn and high fabric quality. The technology is widely applied to spinning processes of common natural fibers, artificial chemical fibers and the like.
When the siro spinning technology is adopted for spinning, two pieces of rough yarn are simultaneously fed into a roller drafting zone, a separator is adopted to separate the two pieces of rough yarn, and the single drafting is kept; the two strands fed from the drawing system are combined and twisted to form a single yarn resembling a plied yarn. Although the siro spinning technology is successfully developed, the single yarn is finally obtained, and the single yarn cannot really replace the plied yarn. Therefore, nowadays when energy conservation and emission reduction are pursued and the problem of labor force deficiency is faced, enterprises urgently need to research and develop a novel spinning technology capable of directly realizing strand production on a ring spinning frame.
In the existing compact siro spinning process technology, the adopted raw materials are basically common viscose fibers, such as the fine-denier medium-long A100-day silk fibers disclosed in CN109576842A, therefore, the disclosed process can only be applied to the common viscose fibers, the common viscose fibers are used as the raw materials, and the yarns prepared by the compact siro spinning process have larger improvements in fiber damage, short fiber rate, straightening parallelism of combed strips and the like, but due to factors such as the self strength of the common viscose fibers, such as CN109576842A, the A100-day silk fibers have strong fibrillation and small fineness, and cotton neps are easily generated in a cotton carding process; in addition, the A100 tencel fiber has strong rigidity and poor cohesion, the fiber is easy to damage in the production process, higher yarn quality still cannot be obtained, the product quality is not high, and the market price is lower.
Therefore, there is a need to provide a new compact siro spinning process to improve the quality of the resultant yarn and to obtain a high quality product.
Disclosure of Invention
The invention aims to provide a production method for spinning viscose compact siro spinning yarns, which solves the problems of poor yarn quality and low product quality of the conventional siro spinning process.
The invention is realized by the following technical scheme:
a production method for spinning viscose compact sirospun yarn takes Yadaier fiber as a raw material, and sequentially comprises a blowing process, a cotton carding process, a first drawing process, a second drawing process, a roving process, a spinning process and a winding process;
in the blowing process, the temperature is controlled to be 29-30 ℃, and the humidity is controlled to be 65-67%;
in one drawing process, the distance of the roller is 12 × 22, the drawing speed is controlled at 280-; the fixed weight and wet weight of the cotton sliver are 19.5 g;
in the two drawing processes, the distance of the roller is 14 × 22, the drawing speed is controlled at 280-; the fixed weight and wet weight of the cotton sliver are 17.25 g;
in the roving step, the twist factor was 82 and the radial winding density was 2900; the quantitative ratio was 3.54g/10 m;
in the spinning process, the draft multiple of the back zone is 1-1.2, the roller distance is 19X 47, the position of the leather roller is 6X 61X 127, the negative pressure is set to 2500-.
The invention adopts domestic high wet modulus regenerated cellulose fiber (Yadaier) as spinning raw material, which has the advantages of higher strength, strong wear resistance, small deformation, high smoothness, better moisture absorption performance, moderate fineness and the like compared with the common viscose fiber.
However, the difficulty of adopting a compact siro spinning process for the high-wet-modulus regenerated cellulose fiber (yali) is higher than that of the common viscose fiber, so that how to explore the compact siro spinning process for the yali fiber is a key, and a functional regenerated cellulose fiber yarn product with high added value and good market favor is developed.
The applicant takes high wet modulus regenerated cellulose fiber (Yadair) as a raw material, improves parameters and steps of a compact siro spinning process, obtains the process of the invention through a large number of experiments, and specifically comprises the following steps:
1) and during the blowing process, accurately controlling the humidity and the temperature of the fiber according to the characteristics of the Yadaier fiber so as to improve the blowing effect and the drawing effect, wherein the temperature is controlled to be 29-30 ℃, and the humidity is 65-67%.
2) And during the drawing process, two drawing processes are adopted, namely a drawing process and a drawing process, wherein the drawing process combines 6 cotton slivers after cotton carding, the unevenness of the cotton slivers is improved, the roller distance is 12 x 22, the drawing speed is controlled at 290m/min, and the diameters of the 4 points of the roller are 35/35/35/35 respectively. The constant-weight wet weight of the cotton sliver is 19.5g, and the straightening parallelism of the fiber is improved through constant-weight drafting; the two drawing processes mainly further improve the straightening parallel degree of the fiber and improve the subsequent spinning quality. The process further improves the requirements on the basis of fixed weight, the fixed wet weight of the cotton sliver is 17.25g, the distance between the rollers is 14 x 22, the speed control is the same as that of one drawing process, the diameters of the points 4 of the rollers are 35/35/35/35 respectively, and therefore drawing quality and drawing stability are improved;
namely, the invention not only improves drawing quality, but also improves drawing stability by reasonably controlling the cotton sliver fixed weight, wet weight, dry weight and roller distance of the first drawing procedure and the second drawing procedure.
3) In the spinning process, through reasonable design of the drafting multiple of the rear zone, the roller distance, the position of the leather roller and negative pressure setting, all parameters are more suitable for the high-wet-modulus regenerated cellulose fiber (Yadaier), and high-quality yarn is spun.
In conclusion, the invention adopts the high wet modulus regenerated cellulose fiber (Yadaier) as the raw material, adopts the yarn forming process with large gauge and small drafting, and concretely embodies the steps of enlarging the roller gauge of the drawing process and reducing the drafting multiple of each process, thereby not only solving the problems of poor yarn quality and low product quality caused by easy damage of the fiber in the production process of the existing common fiber, but also having the advantages of high yarn forming quality and high product quality.
Further, the performance criteria of the jadall fiber are:
the specific strength is 3.20-3.40CN/dtex, the elongation at break is 16-18%, the linear density is 1.22-1.33dtex, and the length is 38 mm.
The document of patent "CN 105525403B" discloses spinning viscose compact siro spinning yarn, and mentions common viscose fiber, the specific strength is about 2.0 CN/dtex.
The patent 'CN 109576842A' discloses a fine-denier medium-length tencel pure yarn, which uses fine-denier medium-length A100 tencel fiber as a raw material, and has the performance medium ratio of 3.94CN/dtex, the linear density of 1.0dtex and the length of 51 mm.
None of the above conventional fibers perform as well as the jadall fibers of the present application.
Further, the specific process of the cotton carding process is as follows:

wherein the cover plate speed is controlled at 140mm/min, the distances between 6 points of the movable cover plate are respectively 10, 9, 8 and 8, the rotating speed of the cylinder is 360r/min, the rotating speed of the licker-in is 800r/min, the gap size between the cylinder and the doffer is controlled at 8mm, the sliver outlet speed is controlled at 140mm/min and the drafting is 90.
Compared with the common viscose cotton carding process, the speed of the cover plate, the rotating speed of the cylinder, the rotating speed of the licker-in, the speed of sliver discharging and the like are reduced, and the drafting is reduced, so that the fiber damage is reduced, and the short fiber rate is reduced.
Further, one drawing process is to combine cotton slivers after cotton carding, wherein the distance of a roller is 12 × 22, the drawing speed is controlled at 280-; the wet weight of the cotton sliver is 19.5 g.
Compared with the common viscose glue integrated process, the process increases the roller center distance, reduces the drafting, and improves the fiber straightening parallelism degree through the fixed weight drafting.
Further, the two drawing processes mainly further improve the straightening and parallel degree of the fibers and improve the subsequent spinning quality. The process further increases the requirements that the weight of the cotton sliver is fixed and the wet weight is 17.25g, the distance between rollers is 14X 22, the diameters of the points of the roller 4 are 35/35/35/35 respectively, the center distance of the rollers is 49X 57, and the speed control is the same as that of one drawing process.
The process arrangement with large gauge and small drafting improves the drawing quality and the drawing stability.
Furthermore, the roving process is to obtain roving after drafting, twisting and winding the drawn sliver obtained by the two drawing processes, wherein the ration of the roving is 3.54g/10m, the twist coefficient of the roving is 80-84, and the radial winding density is 2800-3000.
The technological parameters ensure that the roving forming effect is better, and the backing-off of the sliver on the spinning machine is more facilitated.
Further, the spinning process is that the roving passes through a bell mouth, enters a drafting zone, passes through between a rear roller and a rear leather roller, enters a middle roller, is drafted between a front roller and a front leather roller and then is output through a guide leather roller, and fiber hairiness is further reduced through a special negative pressure device, wherein the drafting multiple of the rear zone is 1-1.2, the distance between the rollers is 19 x 47, the position of the leather roller is 6 x 61 x 127, and the negative pressure is set to be 2500 minus 2700 Pa. The technological parameters ensure that the sliver has good compactness, thereby achieving the purpose of improving the yarn quality.
Furthermore, in the winding process, the winding tension of the winding is set to be 8CN, and the winding speed is 900-1100M/min; the untwisting air pressure is 3.0bar, and the twisting air pressure is 4.0 bar.
The process parameter setting ensures effective detection and removal of harmful yarn defects of the yarn, and ensures certain tension in the yarn winding process, so that the yarn has good stability after being wound into a bobbin.
Furthermore, the devices adopted in the blowing process comprise a CL-P type cotton opener and a MX-V6 type fine cotton opener, and the TC-10 type high-speed cotton carding machine is adopted in the cotton carding process.
Furthermore, an FA-389 type drawing frame is adopted in both the first drawing process and the second drawing process.
Furthermore, an FA-497/498 type roving machine is adopted in the roving process, an FA-503/JWF-1562 type spinning machine is adopted in the spinning process, and an automatic Corner-6 type full-automatic winder is adopted in the winding process.
Compared with the prior art, the invention has the following advantages and beneficial effects:
