The method specifically comprises the following steps:

pattern comb jacquard layer weaving

Guide bar PB 1: warping dyed yarn SCY-0.16MM high bright double-sided reflective fabric/P-DTY 75D/36F semi-bright low stretch double-covered yarn 1, 8 yarns are combed by each pattern comb, PB1 yarn is fully penetrated in the threading of a machine, the gear let-off amount is 1100 MM/wax, PB 1: the content of the PB1 dyed yarn SCY-0.16MM high-brightness double-sided reflective cloth yarn/P-DTY 75D/36F semi-bright low-stretch double-covered yarn of the weft insertion structure 41 and the weft insertion structure is about 0.188%.

Guide bar PB 2: warping dyed yarn SCY-0.16MM high bright double-sided reflective fabric/P-DTY 75D/36F semi-bright low stretch double-covered yarn 1, 8 yarns are combed by each pattern comb, PB2 yarn is fully penetrated in the threading of a machine, the gear let-off amount is 1100 MM/wax, PB 2: the content of the PB2 dyed yarn SCY-0.16MM high-brightness double-sided reflective cloth yarn/P-DTY 75D/36F semi-bright low-stretch double-covered yarn of the weft insertion structure 41 and the weft insertion structure is about 0.188%.

Guide bar PB (1- - - - - - -, N ≥ 0): warping colored yarn SCY-0.16MM high bright double-sided reflective fabric/P-DTY 75D/36F semi-bright low stretch double-covered yarn 1, 8 yarns are combed in each pattern comb, PB (1-N, N is more than or equal to 0) yarns are fully penetrated in a threading mode of a machine table, the gear let-off amount is 1100 MM/wax, and PB (1-N, N is more than or equal to 0): the content of the colored yarn SCY-0.16MM high-brightness double-sided reflective cloth yarn/P-DTY 75D/36F semi-bright low-stretch double-covered yarn of the walking weft insertion structure 41 and PB (1-N, N is more than or equal to 0) accounts for about 0.188%.

Among them, PB1, PB2 are composed of metal wire and flower comb yarn guide needles, which are adhered to the fine metal wire, because the steel wire flower comb yarn guide system. Therefore, no matter how many combs are (1- - -N, N is more than or equal to 0), the combs are parallel and positioned on the same horizontal plane, and PB1 and PB2 are first-layer yarns. The jacquard weaving method has the advantages that the cotton comb lining weft yarns are used for connecting the roots of the loops formed by the warp-knitted ground comb and the jacquard weaving comb only by winding the two ends of the loops, the extending lines cannot be clamped by other yarns, the characteristics of the extending lines floating on the uppermost layer of the surface of the fabric are combined with the unique creel passive warp feeding mode of the jacquard weaving comb, the pattern effect can be formed in any area according to design requirements, and the pattern effect is highlighted by forming lace areas, logo marks, petals, branches and leaves and the like of various brands.

The jacquard area of the lace comb can be matched with reflective yarns and utilizes the reflective characteristic of special materials, so that the lace area presents a reflective effect when light is dark, the lace area and logo marks of various brands are applied to integrated shoes to render unique visual effects, the jacquard area can be positioned on the first layer of yarns, the weft insertion yarns are only wound at two ends and are wound on the root of a coil formed by a warp-knitted ground comb and a jacquard comb by utilizing the characteristic of jacquard comb weft insertion jacquard, the extension lines of the weft insertion yarns cannot be clamped by other yarns and float on the uppermost layer of the surface of a fabric to form obvious jacquard grains, transparent fish silks can be used for jacquard comb, the transparency of the screen cloth is effectively improved, the screen cloth is more beautiful and light in texture, the level aesthetic feeling of the lace product ' flower ' and ground ' is highlighted, and the whole three-dimensional space of the screen cloth is more vivid, the functional effect of the special yarn is utilized to better highlight the layering sense and the technological sense.

And (3) comparison: patent publication No. CN108866793A discloses a multi-bar double-jacquard warp knitting machine and a method for knitting a patterned fabric thereof, which describes a method for knitting a pattern-bar double-jacquard type lace mesh fabric, the process is a single-face double-jacquard process of warp knitting with a jacquard comb, wherein a jacquard lining weft yarn is held in a coil by a warp-knitting ground comb chain, a dark pattern is formed between the front jacquard and the back jacquard, the pattern formed by knitting is relatively flat, and the three-dimensional layering sense is not obvious enough.

Meanwhile, the pattern comb adopts a creel passive let-off mode, creel passive let-off is realized, independent yarn supply is carried out through cone yarn above the creel, each yarn is wound on a bobbin, a row of aluminum strips are arranged at the front section of the bobbin and provided with a ring type pressure tensioner, and the creel passive let-off is realized. The advantages are that: the tension of each yarn can be accurately controlled, so that the tension adjusting machine of the pattern guide is more flexible, and the jacquard effect of the pattern guide bar is enriched. If the pan head positive let-off is adopted: the tension control of the pattern comb is realized by uniformly supplying yarns through the warp beam, which means that the tension of the pattern comb is limited, the jacquard effect is too limited, and the innovation of products is not facilitated.

The yarn material is not limited, because the weft insertion yarn does not participate in the yarn laying before the needle, and only does the needle back transverse movement, the use range of the yarn can be enlarged, the coarse yarn (the D number can be controlled within 50D-900D for realizing the knitting) or other processed functional yarns can be used, in this case, the luminous yarn is matched, and the functional yarns can also be used; TPU, TPEE, reflective yarn, mildew-proof antibacterial yarn and the like can enhance the functional effect of the fabric.
