Split-shaft warping is to divide a whole shaft into several ones, and then combine them into a whole shaft according to the size. For example: the total longitude of a whole shaft is 10,000. There are only 1,000 friends in the lower row, so 10 sub-axes need to be divided. The warp count of each sub-axis is 1000. Each sub-axis must have the same width. If the specified width of the product is 170CM. The width of the sub-axis is also 170CM.
Slitting warping: This is a more iron warping method. As mentioned above, the total length of a whole shaft is 10,000, and the number of friends in the lower row is 1,000, so the whole shaft needs to be divided into 10. The total width of each warp is 17CM, and the total width is 170CM
The length of warping is generally calculated according to the rotation speed of the large garden frame to measure the length of the warp. Such a length calculation method is not very standardized, because as the speed increases, the outer diameter of the large garden frame is increasing, and the diameter is also increasing. The diameter of the large garden frame is generally 2.5 meters, 4 meters, and 5 meters. Most of them are 4 meters. For example, the speed of the first warp is 100 rpm. Then the latter is the same as if it is 100 revolutions, there cannot be more or less, more is called long hang, and less is called short hang. If it is too long, it needs to be cut off, and raw materials need to be consumed; if it is too short, it needs to be connected, and weaving to this part when operating on the machine. Since there are many knots, it is difficult to weave. Even if it has been woven, the nylon fabric is also defective.
The same point of the two warping methods is that the warp threads are first trimmed to the large garden frame belt, and then reeled from the large garden frame belt to the empty disk body.
What is the production process of woolen fabric loom
1. Sizing: Drag the adjusted warp beams to the desizing machine, let the warp surface absorb the pulp through the slurry tank, and air dry it through the drying box. Then put it on the empty plate body. The purpose of sizing is to better bond the single fibers of the silk to each other, increase the elongation at break of the silk, and facilitate the successful weaving of the machine.
With the development of textile equipment, there is now a pulping and coordinating equipment, that is, when warping the sub-shafts, it is no longer based on the capital turnover in the garden frame and the disc, and the silk coming out of the shelf is produced. After facing, it directly enters the slurry tank and drying box. Immediately plate into empty pans. This not only simplifies the process, but also improves economic efficiency and product quality. But the project investment is huge.
2. Parallel shafts; combine the sub-shafts that have passed through the slurry as required. In this way, the length between the shaft and the shaft will be affected by factors such as warping and desizing force, and will change, so you can only dry the smallest one, and cut the long one.
3. Split twisting: In order to facilitate the success of weaving, the warp yarns are divided into left and right double layers with a split twisting machine, and then threaded into the twisted mouth with ropes.
4. Drawing reed: drag a complete warp beam to the drawing workshop, and professional staff will pull out the warp surface, split the strands according to the sub-twisting, separate the warp threads, and thread them into the products specified by the processing technology. in the heald box. This whole process is called weaving. After threading the healds, change the reed knife to fish a certain number of warp threads into the gaps between the reed pieces. This whole process is called fishing reed.
5. Operate textile on the machine. The whole process is divided into reed setting, warp hanging, pattern nailing, and weft density change, and then the trial run can be started.
Wool spinning is the whole process of textile processing that converts wool chemical fiber into cotton yarn. Wool fibers are dominated by wool, and also include special animal hairs such as cashmere, rabbit hair, mohair, and wild yak hair. The wool spinning process can also be used for wool-type fiber pure spinning, blended fabrics, and wool and other natural fiber blended fabrics. Knitted fabrics, woven fabrics, blankets, etc. woven with pure and blended wool yarns have the characteristics of heat preservation, moisture absorption, elasticity and wear resistance. Clothes made of knitted fabrics feel smooth, plump and sharp. Wool yarn is also used to weave industrial-grade cloth, stationery and blankets.
What is wool spinning? Is there any difference between cotton spinning and wool spinning?
The whole process of textile processing that turns flax fiber production and processing into pure cotton yarn and cotton rope. This process is also suitable for spinning cotton-type fiber yarns, mid-length fiber yarns, and blended yarns of cotton and other fibers. Knitted fabrics have good wearing properties, high quality and low price, and the cotton spinning process is very simple, so they play a dominant role in cotton spinning.
As a powerful country in the global cotton textile field, China has a very important influence in the global cotton textile field.
