Knit
circular knitting machine production process of setting one of the elements is to use what kind of yarn, with what kind of knitting needles number. Match fit, the fabric has a significant impact.
Section morphology plain weave fabric, the central highest part, that the thickness is more than 2 times the diameter of the yarn, fabric density, the cross-linear control loop density, and thickness of the yarn, whereas the formation of coverage, which is defined as a coil ratio of the whole area covered with the yarn surface of the area occupied by the called coverage.
Different number of needles have different needle body thickness, the spacing between the needle and its needles, needle groove wall thickness, the three relations, must meet the diameter of yarn. Fabric geometry, a series of formulas to calculate the relationship between the pitch and the yarn, the yarn thickest exceeds the limit, it will not fit this kind of needle and sinker. Earlier when flat fabric seek simple formula listed the number of needles to facilitate reference. Needle = square root (yarn x 20) about the middle of the resulting number is the number of plus or minus 2 needle can be considered. Germany GROZ-BECKERT needles manufacturer, made some of the data, providing needles and yarn count with tables, more convenient to use.
(A) single-sided fabric yarn (UK branch) and pin number relationships: (pin number is the number of stitches per inch)
14-pin = 8.5 / 1 s ----- 14/1 s
15-pin = 10.5 / 1 s ----- 16.5 / 1 s

18-pin = 14/1 s ----- 23.5 / 1 s
20-pin = 18/1 s ----- 26/1 s
22 pin = 21.5 / 1 s ----- 29.5 / 1 s
24-pin = 23.5 / 1 s ----- 35.5 / 1 s
26-pin = 26/1 s ----- 41.5 / 1 s
28 Pin = 29.5 / 1 s ----- 47.5 / 1 s
30-pin = 35.5 / 1 s ----- 59/1 s
32-pin = 41.5 / 1s ----- 71 / 1s
(B) the number of pile fabric of yarn and needles relationship:
12-pin = 2.5 / 1 s ----- 9.5 / 1 s
14-pin = 3.5 / 1 s ----- 12/1 s
15-pin = 4.7 / 1 s ----- 14/1 s
16-pin = 6/1 s ----- 16.5 / 1 s
18-pin = 7/1 s ----- 18/1 s
20-pin = 8.5 / 1 s ----- 20/1 s
22 pin = 10.5 / 1 s ----- 23.5 / 1 s
24-pin = 14/1 s ----- 26/1 s
26-pin = 16.5 / 1 s ----- 29.5 / 1 s
28 Pin = 19/1 s ----- 35.5 / 1 s
30-pin = 21.5 / 1 s ----- 41.5 / 1 s
32-pin = 23.5 / 1s ----- 47.5 / 1s
(C) fine rib fabric of yarn and the number of needles relationship:
14-pin = 16.5 / 1 s ----- 23.5 / 1 s
15-pin = 20/1 s ----- 29.5 / 1 s
16-pin = 23.5 / 1 s ----- 35.5 / 1 s
18-pin = 29.5 / 1 s ----- 47.5 / 1 s
20-pin = 41.5 / 1 s ----- 53/1 s
22 pin = 47.5 / 1 s ----- 59/1 s
24-pin = 53/1 s ----- 71/1 s
(D) Number of double-sided fabric yarn and needles relationship:
14-pin = 12/1 s ----- 16.5 / 1 s
15-pin = 14/1 s ----- 19.2 / 1 s
16-pin = 16.5 / 1 s ----- 21.5 / 1 s
18-pin = 21.5 / 1 s ----- 23.5 / 1 s
20-pin = 23.5 / 1 s ----- 29.5 / 1 s
22 pin = 28.5 / 1 s ----- 35.5 / 1 s
24-pin = 33/1 s ----- 41.5 / 1 s
26-pin = 35.5 / 1 s ----- 47.5 / 1 s
28 Pin = 41.5 / 1 s ----- 53/1 s
30-pin = 47.5 / 1 s ----- 59/1 s
32-pin = 53 / 1s ----- 71 / 1s
(E) Jacquard yarn count and the number of needles relationship:
14-pin = 13/1 s ----- 18/1 s
15-pin = 14/1 s ----- 19/1 s
16-pin = 16.5 / 1 s ----- 21.5 / 1 s
18-pin = 18/1 s ----- 23.5 / 1 s
20-pin = 21.5 / 1 s ----- 26/1 s
22 pin = 23.5 / 1 s ----- 28.5 / 1 s
