DESCRIPTION OF PREFERRED EMBODIMENT

To clarify the technical content, structural characteristics, objective and effects of the technical solution, the disclosure is described in detail below in conjunction with specific embodiment and attached drawings.

Embodiment 1

This embodiment provides a process for weaving three-layer warp-woven fabric with a perspective effect, wherein a dual-needle-bed jacquard warp loom is adopted to weave the fabric,
wherein a front needle bed is programmed to weave transparent monofilaments;
wherein a jacquard guide bar shuttles between the front needle bed and the rear needle bed to generate a middle jacquard design layer, and the jacquard guide bar generates weft insertion stitches at the front needle bed and loop stitches at the rear needle bed.
Jacquard design is concave-convex patterns of fabric which are formed through interlocking of weft and warp yarns.
Weft insertion stitch is a type of design stitch of a warp-knitted fabric, featuring regular weft insertion of non-looped yarns in the traverse direction of fabric. The weft-insertion warp-knitting stitch is classified into two types, namely weft insertion and full width weft insertion. The weft insertion warp-knitting stitch is formed by complete post-needle movement of one or several weft insertion guide bars in the looping process (without pre-needle movement), so that the weft yarns are held between loops and extensions of the background stitch to obtain required properties and effects.
Loop stitch refers to a process of making yarns into loops using knitting needles of the warp loom and other looping devices. On the warp loom, yarns in parallel are guided from the beams and then respectively placed at knitting needles to form loops. Usually, each yarn is only laid in at one or two knitting needles to form transverse loop rows after loops are formed. In one transverse row, each of the loops is interlocked with each corresponding loop in the upper transverse row, so that transverse rows are mutually connected. At the same time, yarns are laid in at different knitting needles in a certain sequence to make the longitudinal columns of the loops mutually correlated after loops are formed, thus generating the warp-knitting fabric.
The use of yarns at needle beds is unlimited, which means that yarns of different sizes and different raw materials can be used.
In this embodiment, the yarn feeding speed of the front needle bed and the rear needle bed is 2000 mm/rack; and the yarn feeding speed of the jacquard guide bar is 4000 mm/rack at the front needle bed and 200 mm/rack at the rear needle bed.
The laid-in yarn stitch of the jacquard guide bar is 1-0-0-0/0-1-1-1//.
Further, two jacquard guide bars are included, namely a first jacquard guide bar and a second jacquard guide bar, wherein the first jacquard guide bar shuttles between the front needle bed and the rear needle bed to form a jacquard middle layer, the first jacquard guide bar generates weft insertion stitches at the front needle bed and loop stitches at the rear needle bed; and the second jacquard guide bar jacquard weaves at the front needle bed or the rear needle bed. In this embodiment, dual jacquard guide bars are accepted, so does a single jacquard guide bar. In case of dual jacquard guide bars, it needs to be ensured that at least one jacquard guide bar jacquard weaves at the front and rear needle beds to generate a middle jacquard design layer, and the other jacquard guide bar can jacquard weave at any needle bed.
