How do we know how many inches and how many stitches we have?

The thickness of the yarn depends on experience, and you can probably know a little bit after watching too much. But to be accurate, you must go to the testing center for testing.

Knitted fabrics are divided into warp knitting and weft knitting. The warp knitting is mainly 24 stitches, 28 stitches and 32 stitches. There are 12 needles, 16 needles, 19 needles for weft knitting, 24 needles, 28 needles, and 32 needles for weft knitting double-sided circular knitting machines, and 28 needles, 32 needles, and 36 needles for weft knitting single-sided circular knitting machines. Generally speaking, the lower the number of needles, the lower the density of the knitted fabric and the narrower the door,

On the contrary, the larger; for example, a 28-needle double-sided circular knitting machine has a total of 2976 needles and a total of 72 channels. If there are 43 needles in one inch, then 2976/43=69.2, and one inch is equal to 2.54CM. Then the door width is 69.2*2.54=175.8CM. There are 323400 needles and 84 channels in total. If there are 48 needles in one inch, then 3400/48=70.8, and the door width is 70.8*2.54=180CM. As seen above,

The larger the number of needles, the larger the width of the door, and the denser the number of needles within an inch. The number of stitches for the cloth mainly depends on the density of the knitted cloth. As far as double-sided machines are concerned, 75D or 100D generally have 24 needles below 40 needles, 28 needles below 43 needles, and 32 needles below 50 needles.
