The satin knitting method is a knitting method in which the interweaving points are discontinuous and regularly and uniformly distributed in the resistance circulation unit at intervals.

In some embodiments, the ratio of the sum of the number of first wefts 201 and connecting wires 202 to the number of second wefts 203 is 4:3; therefore, the thickness of the forming wire can be reduced, so that the dehydration of the forming wire is quickened, the water content in the forming wire is reduced, and the problem of water throwing of the forming wire in the running process is avoided. Specifically, the ratio of the number of connecting lines 202 to the sum of the numbers of the first weft 201, the second weft 203, and the connecting lines 202 is 2/7; that is, the ratio of the number of first wefts 201, the number of connecting lines 202, and the number of second wefts 203 is 2:2:3.
wherein, because of the greater shrinkage of the nylon material, in some embodiments, the connection wire 202 may be a nylon monofilament; to ensure a stronger bond between the top layer 100 and the bottom layer 200.
According to the novel 16-heddle three-layer forming net provided by the embodiment, the surface layer 100, the bottom layer 200 and the connecting wires 202 are arranged, wherein the first warp threads 101 and the first weft threads 201 are interwoven to form the surface layer 100 by adopting a plain weave method, the number ratio of the first warp threads 101 to the second warp threads 102 is 1:1, so that the fiber support index of the surface layer is increased, the fiber retention rate is increased, and the paper forming quality of a paper sheet is improved; meanwhile, the second warp threads 102 and the second weft threads 203 are arranged to form the bottom layer 200 by adopting a 4-harness satin weaving method, so that the structure is tighter, the running load is small, the dimensional change in the running process is small, the running stability is improved, and the service life of the forming wire is prolonged; simultaneously, a pair of connecting wires 202 are arranged to connect the surface layer 100 with the bottom layer 200, one of the 2 connecting wires 202 is connected with the surface layer 100, the other connecting wire 202 is connected with the bottom layer 200, the connecting wire 202 accounts for two sevenths of the total amount of the weft, and the combination of the upper layer and the lower layer is ensured to be firmer by selecting nylon materials with high shrinkage rate; by setting the structure that the ratio of the sum of the numbers of the first wefts 201 and the connecting lines 202 to the number of the second wefts 203 is 4:3, the thickness of the forming net is reduced, the dehydration is quickened, the water content in the net is low, and the water is not thrown in the running process.

Along the thickness direction of the forming wire, 2 connecting wires 202 alternately connect the face layer 100 and the bottom layer 200; that is, one of the 2 connecting lines 202 connects to the face layer 100, and the other connects to the bottom layer 200; the bottom layer and the surface layer are firmly connected together through the 2 connecting lines 202, so that no dislocation exists between the bottom layer and the surface layer, and the combination is firmer and tighter. As will be appreciated by those skilled in the art in conjunction with fig. 3, the first weft yarn 201 interweaves with the first warp yarn 101 to form the face layer 100, the second weft yarn 203 interweaves with the second warp yarn 102 to form the bottom layer 200, and the connecting wire 202 is interposed back and forth between the face layer 100 and the bottom layer 200, so that the first warp yarn 101 and the second warp yarn 102 are tightly bound together, and by the above interweaving manner, the fiber support index of the forming wire 1 can be increased, so that the sheet is uniformly formed, the water content in the forming wire is less, the dewatering is faster, and the upper layer and the lower layer are more tightly and firmly combined.
