BRIEF DESCRIPTION OF DRAWINGS To describe the technical contents, structural features, objectives, and effects of the technical solutions in detail, the following detailed embodiments will be described in detail with the accompanying drawings.

Example 1

This embodiment provides a weaving process of a three-layer warp knitted fabric in which an intermediate shape is projected, which is woven using a double needle bed jacquard warp knitting machine,

The front needle bed is woven using transparent monofilament;

The one jacquard guide bar reciprocates in front of the front needle bed and the rear needle bed to sew to form a mezzanine jacquard weave, the jacquard guide bar forms a weft insertion tissue in the front needle bed and a loop forming tissue in the rear needle bed. .

Jacquard weave is an uneven pattern formed by crossing the warp and weft of a textile material.

The weft insertion tissue is one design and color organization of the knit fabric, and is characterized by inserting a weft yarn that does not form a loop periodically in the transverse direction of the knit fabric. The warp weft insertion tissue is divided into partial weft insertion and full weft insertion. The partial weft insertion tissue uses only one or several weft insertion guide bars to move only behind the needle during the loop formation process and does not move forward in the needle, so that the weft insertion yarn is sandwiched between the needle loop and the extension line of the knitting tissue. This gives the necessary properties and effects.

Loop forming tissue is the process of causing the yarn to form a loop using knitting needles and other loop forming parts on a warp knitting machine. On the warp knitting machine, parallelly arranged warps are drawn out of the beam and placed on each knitting needle, respectively, to form a loop. Each yarn typically wraps only one or two knitting needles each time and forms a loop row after loop formation. In this row, each loop is all interlooped with the loop corresponding to the row, and the row and row are connected to each other. In addition, the yarn is wrapped in different knitting needles in a certain order, and after the formation of the loop to form a connection between the longitudinal cross-section of the loop to form a warp knitted fabric.

The use of the spun yarn of each needle bed is not limited, and spun yarns of different thicknesses and different raw materials may be used.

The feeding amount of the front needle bed and the rear needle bed are both 2000 mm / rack; The delivery amount in the front needle bed of the jacquard guide bar is 4000 mm / rack, and the delivery amount in the rear needle bed of the jacquard guide bar is 200 mm / rack.

The wrap organization of the jacquard guide bar is 1-0-0-0 / 0-1-1-1 //.

Furthermore, it comprises two jacquard guide bars, each of which is a first jacquard guide bar and a second jacquard guide bar, the first jacquard guide bar reciprocating in front of the front needle bed and the rear needle bed to sew to form an interlayer jacquard weave. The first jacquard guide bar forms a weft inserting tissue in the front needle bed and a loop forming tissue in the rear needle bed; The second jacquard guide bar is jacquard weave in either the front needle bed or the rear needle bed. In the present embodiment, it may be a double jacquard or a single jacquard, but as a precondition, at least one jacquard is jacquard weave in the front needle bed and the rear needle bed, the middle layer weave, and the other jacquard is optional Jacquard weave in the front needle bed and the rear needle bed.
