Referring to fig. 11, fig. 11 is a third yarn laying motion diagram in the method for manufacturing a sandwich mesh fabric with three-dimensional engraved jacquard of the present invention.

The jacquard guide bar JB1 lays yarn on the front needle bed and changes the satin stitch 0-1/1-1/2-1/0-0// forms the engraved jacquard layer 1;

jacquard bar JB2 lays the yarn on the front needle bed and runs a varying satin stitch 0-1/1-1/2-1/0-0// forms the engraved jacquard layer 1;

the jacquard guide bar JB3 lays yarn on the front needle bed and changes the satin stitch 1-1/1-0/1-1/1-2// forms the engraved jacquard layer 1;

the jacquard guide bar JB4 lays yarn on the front needle bed and changes the satin stitch 1-1/1-0/1-1/1-2// forms the engraved jacquard layer 1;

the ground guide bar GB5 is sequentially laid with yarns alternately on the front needle bed and the rear needle bed and changes the warp knitting texture 1-0/2-1/2-3/1-2// to form the engraved layer 2, and concretely, the ground guide bar GB4 is knitted by a looping process on the warp knitting and velvet texture 1-0/2-3//, on the front needle bed (namely the engraved layer 2 is on the engraved jacquard layer 1); the ground guide bar GB4 walks a warp knitting chain stitch 2-1/1-2//, on a back needle bed (namely the engraved layer 2 is on the engraved base layer 3), and the looping process is carried out for knitting;

a ground guide bar GB6 is laid on a back needle bed and a warp knitting organization 1-0/0-1/1-2/2-1// forms the engraved base layer 3;

the ground guide bar GB7 is laid on the back needle bed and passes through the twill stitch 3-4/1-0// forms the engraved base layer 3.

In the threading step, stitch pattern change is adopted by the jacquard guide bar JB1, the jacquard guide bar JB2, the jacquard guide bar JB3 and the jacquard guide bar JB4, so that coil extension lines are superposed, and the concave-convex touch feeling and the visual feeling of the engraving effect are enhanced.

The sandwich screen cloth is woven by the high-speed jacquard machine with the double needle beds, the three-dimensional engraving jacquard 11 is woven by the threading change of the guide bar and the local miss stitch process, so that the screen cloth has good air permeability, wrinkle resistance and shape retention, the 3D stereoscopic impression is strong, the engraving effect is strong, the air permeability of the screen cloth in the prior art is poor, obvious concave-convex touch and visual sense do not exist, the concave-convex embossment effect is only achieved, and the technical difficulties such as the engraving effect do not exist.

The guide bar of the weaving and engraving layer 2 is set to a double-needle bed process in the embodiment, and the front needle bed and the rear needle bed are sequentially and alternately laid with yarns and knitted in a loop mode, so that the structure of the sandwich mesh cloth is more stable.

The sley bar of weaving fretwork jacquard layer 1 in this embodiment adopts two yarns and does a yarn and wear the yarn, strengthens yarn D number, strengthens unsmooth sense of touch, the sense of sight of fretwork effect.

The manufacturing method of the embodiment is simple, and the three-dimensional engraving jacquard 11 is woven by utilizing the threading change of the guide bar and the local drop stitch process, so that the three-dimensional (3D) stereoscopic impression of the sandwich mesh cloth is strong, the engraving effect is strong, the concave-convex sense is more prominent, and the concave-convex touch sense and the visual sense are greatly enhanced.

To sum up, the embodiment adopts the merchant card comb to carry out the fretwork jacquard weave for the screen cloth has good gas permeability, anti fold nature, shape preserving nature, and the 3D third dimension is strong, and the fretwork effect is strong, and it is relatively poor to have broken through prior art screen cloth gas permeability, does not have obvious unsmooth sense of touch, the sense of sight, only has unsmooth relief effect, does not have technical difficulty such as fretwork effect. And embodiment 2-3 are that the fretwork is carried out to the comb more and carve the jacquard weave, and when the screen cloth had good gas permeability, anti fold nature, shape keeping nature, its 3D third dimension is stronger, and unsmooth sense of touch and look are more outstanding and clear, and the fretwork effect is stronger.

The embodiment 1-3 adopts a double-needle bed high-speed warp knitting machine to integrally knit, and utilizes the threading change of the guide bar and the local miss stitch process to knit the three-dimensional engraving jacquard 11, so that the sandwich mesh cloth has strong 3D stereoscopic impression, strong engraving effect and more prominent concave-convex feeling, and the concave-convex touch feeling and visual feeling are greatly enhanced. And embodiment 4 adopts the high-speed merchant card machine of two needle beds to weave integratively, utilizes the threading change of sley bar and local drop stitch technology to weave the three-dimensional engraving jacquard weave 11 that has more the specialty for sandwich screen cloth's 3D third dimension is stronger, and the engraving effect is stronger, and unsmooth sense is more outstanding, has strengthened unsmooth sense of touch and has looked the sense greatly.
