[0028] S2. Weaving treatment: Weft knitting and plain weft knitting are used. In post-processing, the setting temperature of the setting machine is higher than the melting point of low-temperature melting polyester, so that the intersection of the coils is adhered, and the knitted fabric with fixed coils and stiff surface is obtained. After setting, the mesh is similar to a square.

[0029] Model selection: Single-sided 30" 18G90F (total number of needles 1680)

[0030] Organization: Weft plain needle organization

[0031] Design mesh size: side length A (unit: m, e.g. Figure 1 (shown)

[0037] T represents the total number of needles in the circular knitting machine;

[0038] A (unit: m) is the side length of the designed mesh size;

The core-sheath polyester filament structure used in the raw material selection is: the core is ordinary polyester, and the sheath is low-temperature melting polyester. The yarn fineness is 150D.

[0052] S2. Weaving treatment: warp knitting warp plain needle organization is adopted. In the post-processing, the setting temperature of the setting machine is higher than the melting point of low-temperature melting polyester, so that the intersection of the coils is adhered, and the knitted fabric with fixed coils and stiff cloth surface is obtained.

[0053] Model selection: Z303E12

[0054] Organization: Economic and Peaceful Organization

[0055] A single warp knitted coil structure can be viewed as an oblique square consisting of 1 coil + 1 extension line (such as Figure 2 (shown)

[0056] Assuming that the length of the single side of the coil and the ductility length are both A (unit: m), the length of the yarn used for a single coil is L1=3A. Figure 3 (shown)

[0057] From the above, we can see that the length of a single coil organization in the warp and weft directions is

[0058] Let the number of yarns in a single warp beam of a warp knitting machine be T (usually 370). The fabric designed in this article requires 3 warp beams, that is, 3T.

[0059] The fabric width can be obtained as (Unit: m)

[0060] The fabric is made of single yarn (filament), and the yarn count is D

[0061] The weight of a single coil yarn is (3A*D) / 9000=AD / 3000 (in g)

[0062] 1m 2 The number of coil organizations is (Unit)

[0063] The fabric weight can be obtained as (AD / 3000)*(1 / 2A2)=D / 6000A (unit: g / m 2 ) In summary, the width and weight of the fabric blank are (g / m 2 )

[0064] The length of the single coil structure A is designed to be 0.0015m

[0065] Effective width of finished fabric:

[0066] Finished fabric weight: D / 6000A=150 / (6000*0.0015)=16.6g / m 2

[0067] The grey cloth is shaped by a shaping machine to obtain a knitted fabric with fixed coils and a stiff surface.

[0068] S6. Forming treatment: The finished fabric is formed by a forming machine.

[0069] S7. Quality inspection: Conduct strict and comprehensive quality inspection on finished fabrics, using a combination of manual visual inspection and instrument inspection. Repair or cut unqualified parts found during the inspection in a timely manner.

[0070] The process examples described above are merely illustrative, and similar processes may be selected according to actual needs to achieve the purpose of the present embodiment. Those skilled in the art may understand and implement the process without inventive effort.
