Description

Technical Field

[0001] The invention relates to the field of textiles, and in particular to a method for making a three-dimensional laminated fabric. Background Art

[0002] Existing louver-style laminated fabrics are generally made by cutting a plurality of strips of fabric, stacking one piece of fabric on top of another, and then sewing the pieces together to form a laminated fabric. The edges of long strips of fabric are very easy to curl, and the fabric will deform when slightly stressed. When sewing the multiple pieces of fabric together, the fabric will be uneven, and the deformation of the fabric will be inconsistent, resulting in a skewed laminated fabric, which has a poor overall visual effect. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned shortcomings and provide a method for manufacturing a three-dimensional laminated fabric with consistent fabric properties.

[0004] To achieve the above object, the technical solution of the present invention is: a method for making a three-dimensional laminated fabric, comprising the following steps: The nth piece of material is knitted with the nth set of knitting needles, where n is an arithmetic progression of positive integers with a tolerance of 2, and the n+1th piece of material is knitted with the n+1th set of knitting needles, and the left half of the n+1th piece of material is located above the right half of the nth piece of material; After the nth piece and the n+1th piece have been woven for a length of l, the nth piece and the n+1th piece are sewn together at the overlapping position of the nth piece and the n+1th piece with yarn to form a sewing point; All the woven sheets form a three-dimensional laminated fabric, and the three-dimensional laminated fabric is cut and processed to form a three-dimensional laminated fabric.

[0005] After the sheet is woven for a certain distance, a stitching point is generated. At this time, the position of each sheet is still restricted by the flat knitting machine or knitting needle. During the stitching process at the stitching point, the force and position of each sheet are not much different. The overall properties of the three-dimensional laminated fabric composed of multiple sheets are uniform.

[0006] Preferably, the nth set of knitting needles includes a plurality of first knitting needles arranged in a row in the left-right direction, the n+1th set of knitting needles includes a plurality of second knitting needles arranged in a row in the left-right direction, and the first knitting needles in the left half of the nth set of knitting needles and the second knitting needles in the right half of the n+1th set of knitting needles are arranged alternately. The first knitting needles and the second knitting needles knit two adjacent sheets at the same time, and the stacking range of the two adjacent sheets remains unchanged.

[0007] Preferably, the method further comprises the following steps: The three-dimensional laminated fabric is flattened on a platform, and the cloth strips are sewn on the stitching points of the three-dimensional laminated fabric along the left-right direction. Two adjacent cloth strips on the three-dimensional laminated fabric are staggered and sewn on the second fabric. The three-dimensional laminated fabric and the second fabric form a three-dimensional laminated fabric.

[0008] The stitching points of multiple pieces at the same length position are sewn together on a strip of cloth. Multiple parallel strips of cloth can be sewn on the three-dimensional laminated fabric. Adjusting the position of the strips of cloth can drive multiple pieces of material to deform together, and the shapes after deformation are regular and neat.

[0009] Preferably, the method further comprises the following steps: The three-dimensional laminated fabric with cloth strips sewn thereon is fixed on a multi-layer rotating drum, which includes a rotating shaft and a plurality of coaxial rotating drums arranged in a row. The rotating drums are rotatably arranged on the rotating shaft, and each rotating drum is provided with a circle of fixing rings. The three-dimensional laminated fabric is fixed on the multi-layer rotating drum in the manner of one cloth strip being fixed on one fixing ring. Rotating the drum on the multi-layer drum so that the three-dimensional laminated fabric is twisted in a first manner, and spraying a first paint on the three-dimensional laminated fabric; rotating the drum on the multi-layer drum so that the three-dimensional laminated fabric is twisted in a second manner, and spraying a second paint on the three-dimensional laminated fabric; The three-dimensional laminated fabric sprayed with the first paint and the second paint is taken off from the multi-layer drum, and the three-dimensional laminated fabric and the second fabric form a three-dimensional laminated fabric.

[0010] The rotation can drive the cloth strips to rotate, so that the overlapping parts between the sheets are exposed, the first paint and the second paint can enter the overlapping parts between the sheets and adhere to the sheets, and after the three-dimensional laminated fabric is removed from the multi-layer drum, the sheets are restored to overlap, and the first paint and the second paint in the overlapping area can pass through the sheets to produce a continuous and new color pattern with the exposed first paint and the second paint.

[0011] By adopting the above-mentioned technical scheme, the beneficial effect of the present invention is as follows: a stitching point is generated after the sheet material of the present invention is woven for a certain distance. At this time, the position of each sheet material is still restricted by the flat knitting machine or the knitting needle. During the stitching process at the stitching point, the force and position of each sheet material are not much different. The overall characteristics of the three-dimensional laminated fabric composed of multiple sheets are uniform and consistent, and the overall shape of the manufactured three-dimensional laminated fabric is stable without any abrupt changes.
