The three thread circular knitting machine knitting yarn covering the ground yarn fabric belongs to a more special fabric, the machine debugging security requirements are also higher, theoretically it belongs to the single jersey add yarn covering organization, but the knitting process and single jersey machine knitting add yarn covering organization of the process there is a difference between the following we do an analysis in this regard
When single jersey machine is knitting the yarn covering organization, the ground yarn and the face yarn are fed into the hook of the knitting needles in the knitting area at the same time through the same yarn guide, through the ground yarn and the face yarn are fed at different angles (transverse and longitudinal angles), which makes the ground yarn and the face yarn have different positions in the hook of the knitting needles, i.e. the ground yarn is far away from the needle bar, and the face yarn is close to the needle bar, and the ground yarn is higher or lower than the face yarn, and then through the control of the tension of ground yarn and the face yarn, it is ensured that the ground yarn and the face yarn are in the same position when bending yarn off and backward loop. When bending the yarn off the retreat circle, to maintain the relative position of stability, so that the veil is always in the front of the fabric. This process has been discussed in detail before, and will not be repeated here.
The three thread circular knitting machine, ground yarn, face yarn is fed through two different guides to the needle hook, how to ensure that the ground yarn, face yarn in the needle hook position is relatively stable, the evaluation of the sweater machine to cover the effect of good or bad key. The three thread circular knitting machine in the knitting process to go through three yarn guides were fed into the liner yarn (commonly known as loop yarn) yarn ground yarn, to form a complete fabric row, when the knitting needles through the knitting veil of the triangle (commonly known as the human triangle), the veil was padded into the needle hook, but in the process, Oyasama two corner only bending yarn did not come out of the loop, and the previous column of the old coil is still on the needle bar, the new padded into the veil is still left in the needle hook, and not bent! It is not bent into a loop. The machine continues to run through the knitting ground yarn of the triangle (price called small two angles) on the needle, but on the child height is limited, the height of its rise relative to the two angles, only to reach the height of its set of loops to ensure that the new feed of the yarn does not retreat from the tongue of the needle, still remain in the hook, as shown in Figure 1. Then the needle begins to fall, the ground yarn is padded into the hook, at this time, the ground yarn, the relative position of the face yarn in the hook as shown in Figure 2, the ground yarn on the top, the jersey yarn.Ground yarns on the front side of the fabric, ground yarns on the back side of the fabric.
To solve these problems, the following two aspects should be considered.
a. Ground yarn, face yarn coil length should be different (ground yarn short, face yarn long), and the difference should be people to do so in order to make the large part of the cloth tension on the ground yarn, rather than acting on the face yarn, so that the face yarn in the de-circling is not subject to the influence of the tension of the cloth, the virtual attached to the ground under the yarn coil, with the ground yarn coil of the de-circling and de-circulation, will not happen in the de-circling process of the face yarn over the phenomenon of the ground yarn. Generally, the length of the yarn is 1.2~1.6mm longer than that of the ground yarn (when the ground yarn is spandex).
knitting village cushion yarn, due to part of the knitting needles on the production and pull not on the production of knitting needles on the ground yarn, yarn hair cattle tumbling, to solve this problem, the general use of the cushion yarn this way of the triangle depressed method, the purpose of the use of the sinker piece of jaws will be open on the needle on the needle on the coil picked up, pulled tight, in order to overcome the upper open needle on the coil of the pull, such as the Figure 3 is small. However, it should be noted that when the machine lining yarn on the flat needle triangle stitch width is too wide this method is ineffective, and this type of machine is also not suitable for knitting overlay type of sweater fabrics.
Through the above adjustments, generally will knit a good effect of fleece fabric but when the local yarn for polyester-cotton yarn, polyester-cotton yarn and polyester filament is very easy to occur adhesion, in the debugging process not only to pay attention to the above two points, but also will be sinker piece of the two corners of the direction of the center of the circle of the needle Jane advance, this is the mountain in the pad of the person's face yarn only curved yarn did not become a circle, when it enters the lesser mountain triangles, due to the needle's ascent, the yarn is completely relaxed, and when it enters the lesser mountain triangles, due to the needle's rise, yarn is completely relaxed, the needle's width is far greater than the needle heel width, this approach is invalid, and such machines are not suitable for knitting covered sweater fabric. When in contact with the ground yarn (spandex silk 1, easy to stick caused by tumbling, inward push the tight small mountain sinker triangle is to sinker of the upper part of the tiger's mouth will be pushed tightly to avoid sticking to the veil.
