The decisive factor for the quality of any roughening of the surface of the knitted product is the arbitrary roughening system, wherein stability plays a key role. In the process of arbitrary roughening, the process of arbitrary roughening is completed through the sinker, when the arbitrary roughening sinker is selected at high speed, any napping of the head of the sinker slightly up or down causes a reduction in the napping quality.
In order to solve the problems existing in the prior art, long-term exploration is performed, and various solutions are proposed. For example, chinese patent application No. 201120488031.8, publication No. 202347223U, publication No. 2012-07-25 discloses a device for matching any napping sinker and outer sinker of a hosiery machine, the device includes an outer sinker and a sinker with a stitch and an upper guide bar, the outer sinker is composed of an upper outer sinker and a lower outer sinker, the upper end of the upper outer sinker is uniformly distributed with an upper guide groove, the lower end is an annular boss concentric with the upper end, the inner diameter of the lower end is the same as the inner diameter of the upper end, the outer diameter of the lower end is smaller than the outer diameter of the upper end, the difference between the outer diameters of the upper end and the lower end is slightly larger than twice the length of the stitch, the height of the lower end is slightly smaller than the height of the stitch, the lower outer sinker is an annular ring of an upper outer guide groove, the inner diameter and the outer diameter of the lower outer sinker are the same as the upper outer sinker, the inner diameter of the upper outer sinker is slightly smaller than the diameter of the upper guide groove, the difference between the lower guide groove and the lower guide bar is slightly smaller than the length of the stitch, and the lower guide bar is slightly smaller than the length of the stitch.
In the technical scheme disclosed above, the outer sinker is composed of two parts of structures of which the upper part and the lower part are respectively provided with a guide groove, so that the problem that any napped sinker is broken and inconsistent in height to generate bad socks in the process of entering the outer sinker is effectively solved. However, after the sinker is selected by the needle selector, the guide block above the needle selector bends the sinker due to the thrust of the needle selector in the process of entering the jacquard triangle guide surface, the tail part of the sinker is tilted, and the sinker is very easy to collide with the jacquard triangle to break, so that the damage of a machine and the bad phenomenon of a knitting product are caused.

6. The napping jacquard needle system according to claim 2, wherein a small eyebrow is provided between the inner needle guard and the outer needle guard.
7. A needle routing method employing the needle routing system of claim 5, comprising the steps of:
Firstly, a needle selector selects jacquard control needles at corresponding positions by computer control according to the pattern set by a computer; then, the inner sinker disc assembly and the outer sinker disc assembly rotate along with the needle cylinder, jacquard control needles are inlaid in needle grooves of the outer sinker disc and rotate together with the sinker disc assembly, and the needle selector is fixedly arranged on a sinker cover which does not generate displacement change;
When the jacquard part is needed on the knitting product, the jacquard control needle rotates to the needle selecting triangle of the needle selecting device along with the sinker disc assembly, the needle selecting triangle acts on the jacquard tooth to push the jacquard control needle to move along the needle groove towards the axis direction, the jacquard needle in the jacquard control needle track groove acts on the slope surface of the jacquard control needle by the convex point in the jacquard control needle track groove to push the stitch of the jacquard needle out of the needle groove, the stitch of the jacquard needle contacts with the inner needle moving inclined plane, the jacquard needle is pushed to move along the outer sinker disc needle groove towards the axis under the action of the inner needle moving inclined plane, the jacquard needle pushes the sinker sheet to perform the jacquard work, meanwhile, the front section of the needle bar of the fluffing jacquard needle pushes the front section of the track groove of the jacquard control needle to move inwards, the stitch of the fluffing jacquard needle reaches the slope surface after passing through the inner needle-moving surface, the stitch of the jacquard control needle pulls the jacquard control needle to move along the opposite direction of the axis of the needle groove of the outer sinker disc under the action of the outer slope surface II, meanwhile, the fluffing jacquard needle in the track groove is pulled to move along the opposite direction of the axis, at the moment, the stitch of the fluffing jacquard needle passes through the slope surface, and the slope surface acts on the stitch of the fluffing jacquard needle, so that the stitch of the fluffing jacquard needle is pressed into the needle groove of the outer sinker disc to prepare for the next fluffing jacquard to work, and meanwhile, the sinker disc continues to rotate;
when the part of the knitting product which does not need the fluffing jacquard is driven by the needle cylinder to rotate to the corresponding position of the needle selector, the needle selector does not start the needle selecting triangle, so that the jacquard control needle and the fluffing jacquard needle do not participate in the work, the stitch of the fluffing jacquard needle is continuously remained in the needle groove of the outer sinker disc and passes below the jacquard needle moving track, at the moment, the fluffing sinker is not pushed by the fluffing jacquard needle to do the fluffing work, and the inner stitch surface of the fluffing sinker passes through the inner needle moving surface of the middle eyebrow to do the flat loop and do not the fluffing work;
The jacquard control needles which are not selected by the needle selector do not push the napping sinker to carry out napping action.
