Siro spinning is two rovings are fed to drafting at the same time & twisted together as a double yarn.
Benefits of Siro Compact Spun:
Low hairiness, low thin and thick neps, smooth & good abrasion resistance, good wear resistance,
better fiber orientations, fewer joints, fewer variations in the uniformity in the yarn.

[Wool Net] 1 The mechanical part is not accurate. Due to the low precision of the equipment, or the aging of the mechanical equipment, the single piece of the syringe is plagued by the degree of plague and peace, and the synchronous data is out of the allowable range, the change and fluctuation of the yarn tension will be felt as usual. Such cross-paths, such as coils and sizes, will generally disappear after adjusting the mechanical data.
2, the problem of the yarn feeder and the wire feeder, in some manufacturers with a lot of flying words and poor dust removal system, the sliders accumulated in the yarn trays for a long time are not cleaned, the slider rubber sleeve is aging, As for the belt answering, the speed is abnormal, the yarn feeding speed is slow and the cross road is generated, the yarn feeder is flying, and the upper and lower counter gears are not in the transmission position. As soon as the yarn is turned on, the yarn is in a negative state, and the cross path is generated.
3 debugging problems, in the debugger, the triangular depth of the upper and lower needles is not the same, resulting in the size of the cloth coil, creating a cross-road, such problems are generally regular, because the depth of the upper triangular needle is compared with the naked eye Difficult, so when we debug the machine, we first press the needle bar to the depth position of the needle, and then adjust the needle. At this time, the tension of the yarn is taken as the standard. In this process, we will encounter such a The common phenomenon is the rib cloth. On the cloth surface, the middle of the circle with two straight lines of straight lines will be small for a while. The reason is that the upper needle is not pressed. This phenomenon is also found in cotton wool. Very ugly, and because the unevenness of the upper and lower triangles will also lead to this phenomenon, the concept of this division is that the upper and lower fits on the circumference are not equally divided, so that the needles are not consistent when the cloth is formed. This problem is hard to see with the naked eye.
4, raw material problems, raw material problems are more common, the resulting cross-road form has yellow and white strips. Irregular cloud spot cross-roads, such cross-paths can generally be solved after yarn change, but some are hidden cross-paths. Such cross-roads are the most troublesome. The yarn quality is poor, the twist is not uniform, and the yarns are mixed, which will cause such problems. The horizontal strip of spandex cloth is also one of the common problems, and some of the poor quality spandex problems are more. For example, the stickiness is too big and fluffy.
5, the problem of chromatic aberration, sometimes we will encounter such a situation, that is, there is no cross-section on the rough, but the light blank is all cross-road. At this time, the weaving will be said to be a bleaching problem, and the bleaching will be a weaving problem. I once heard a friend say this to me: This is because the color difference of raw materials is not good, and it is okay to dye light color or bleach. It seems a bit reasonable, but whether it is really like this, I have no research. About this topic, there is a friend who has been dyed and said here.
6, the creel guide yarn structure problem, such problems occur in the terry machine, especially when the F-number of the open filament is high, generally the cross-path produced by the tension or tension of the yarn guide structure, such cross-road is not obvious, so Some factory commissioners will check the tension between the floor creel or the yarn feeder.
7. The problem of stopping the cross-road is generally the problem of the clearance between the gear and the large gear of the main shaft and the clearance between the base of the large disc and the large gear. The thicker the opening is, the more serious the stop is, and the reduction of such cross-way debugging is achieved at the most. Not very likely, because it has been qualitative at the factory.
Bar knitting yarn solve the problem of technology and management for the chance of knitting yarn bar will be considerably reduced, regardless of knitting yarn to produce bar under what circumstances, will give knitting yarn, knitted fabrics manufacturers brought very A large economic loss, whether the yarn for knitting will produce a horizontal strip in the dyeing process of the knitted fabric in the later process will only be known after dyeing. The appearance of knitted fabric strips has problems in cotton mills, as well as problems in knitting factories and dyeing and finishing plants. The following rules of thumb are generally used for the classification of knitted fabric strips: 1 cotton spinning mills have regularity and horizontal stripes are obvious, generally Is caused by the unevenness of certain single yarns,
The wrong number, the weight deviation is too large, the Cotton Yarn is produced by single or multiple mixed batches; 2The knitting factory produces regular horizontal strips, which are generally due to the uneven tension of some needles on the knitting machine or the use of cotton yarn in the knitting factory. No., wrong batch; 3 dyeing and finishing factory produced knit strips, generally show that the horizontal bar is lighter or the bar does not have any regularity, the main reason for this horizontal bar is the time of knitwear in the dyeing tank Too long, or the knit cloth in the dyeing tank wrinkles so that the dyeing liquid can not penetrate, the difference in the concentration of the dyeing liquid is too large, and the poor dyeing quality will also cause the dyeing strips to appear in the knitted fabric ; 4 caused by irregular strips The reasons are: mixed cotton unevenness, raw cotton replacement use is not regular, cotton maturity is large, cotton sliver mixing is uneven, cotton yarn length and length are more details, dyeing pressure is not enough, dyeing liquid concentration is not uniform, dyeing steam temperature is not enough, The dyeing tank is not clean, and the cotton cloth is scoured in the dyeing tank for too long. 5 Reasons for the regular strips: There are both the reasons of the cotton mill and the factors of the knitting factory. The reasons for the cotton mill are uneven and wrong.
The technical measures for solving the cross-strips of knitting yarn include: stabilizing the quality of the blended cotton, preferably mixing the cotton one at a time; stabilizing the replacement ratio and time of the cotton; reducing the difference in twist between the spindles, controlling the sliver, combing The uneven weight and weight deviation of the strips and strips prevent the cotton yarn from mixing and batching, preventing the formation of long and thick sections and long details. Management description includes: formulating quality control standards for mixed cotton and implementing inspection of package inspection, performing operation management with flawless spinning, strengthening maintenance management of equipment, and strictly blocking the dead links of the spinning mills. , mixed tube, wrong tube color, etc.).
