This standard specifies the number of needles commonly used for single-sided, double-sided and double-sided large nominal diameter circular knitting machines based on the needle length or machine gauge E and the nominal diameter of the machine. It can be used as a basis for comparison of knitted fabrics.

Number of needles for circular knitting machines with large nominal diameter
This standard specifies the number of needles for circular knitting machines with large nominal diameters and the number of needles for circular knitting machines with large nominal diameters based on the machine number of needles and the nominal diameter of the machine. The space can be used as a basis for comparison. Note: 4 Machine tooth adjustment and terminology calibration are specified in H-1. Normative references
The following documents are used as references to this standard. For dated references, all subsequent amendments (excluding the contents or revisions) are not applicable to this standard. However, all parties to the proposed standard are encouraged to study whether the latest versions of these documents can be used. For undated references, the latest version shall be used for this standard. GB6002.1-1H3: Textile Machinery Technology Loom Classification and Technical Specifications (IE115753: 19841G/T5-CC3 TS117: 1D> GB/T84582C3 Loom Micro-diameter 3.1 The nominal diameter of the machine is represented by the theoretical diameter of GB/54562903 and GB/T8452033. The commonly used count is determined by rounding the nominal diameter to 5usmn. When the nominal diameter is m8mm, take 2f. In the case of ", the deviation of the theoretical number shall not exceed: in the case of b, the difference is close to: the normal monthly needle count (the forbidden point is: 12 counts within 21 parts, it is limited by the theoretical tolerance: that is, * or within: 3. 2 Count the theoretical count N, and the following calculation formula is obtained: N, E, where N is the theoretical needle count, #=3. 1415927; d is the loom number; and NV is the machine number. The number of needles in the loom is 3.1. For example: 2, 18 warps, the theoretical number of the machine number 2 is N, 1N 3. 1415927 × 241 357. 53. Therefore, the common needle count ranges from 18.1 to 13.16, that is, 1317.1, and the smallest number that can be divided by 12 is 1355. GB/TR457—2003/1S0A122:1988. 3st?
