Description

Technical Field

[0001] The invention belongs to the field of textile technology, and in particular relates to a method for knitting a three-dimensional ornament on the outer side of a tubular knitted fabric. Background Art

[0002] Over time, tubular knit fabrics have evolved. Initially, hand knitting involved using hands and needles to create tubular fabrics, a traditional but inefficient method. Subsequently, the advent of hand-cranked flat knitting machines improved production efficiency, making tubular knit fabrics even faster to create. Today, computerized flat knitting machines utilize computers to control knitting, significantly increasing production efficiency and design possibilities.

[0003] With advances in knitting technology, the design of tubular knitted fabrics has evolved from simple flat fabrics to fully computer-controlled jacquard fabrics. Although it is now possible to weave complex patterns on the surface of tubular knitted fabrics, weaving three-dimensional ornaments within the three-dimensional structure of tubular knitted fabrics, especially on the outside of tubular garments, remains a technical challenge. Summary of the Invention

[0004] In order to achieve the goal of knitting a three-dimensional ornament on the outside of a tubular fabric on a computerized flat knitting machine, the present invention provides a method for knitting a three-dimensional ornament on the outside of a tubular knitted fabric, the specific steps of which are as follows:

[0005] Step (1): knitting a weft flat tubular fabric between the front and rear needle beds with one needle between them, wherein the needles involved in the knitting on the front and rear needle beds are the first needles, the needles not involved in the knitting on the front needle bed are the idle needles one, the needles not involved in the knitting on the rear needle bed are the loop needles and the idle needles two, and the loop needles and the idle needles two are separated by the first needle of the rear needle bed;

[0006] Step (2): If the three-dimensional ornament is convex (bulgy), at the part where the convex (bulgy) is locally knitted, the coil on the first needle of the front needle bed is turned over to the corresponding idle loop knitting needle of the rear needle bed through the process setting of the electric control board, and the idle knitting needle 1 of the front needle bed and the idle knitting needle 2 of the rear needle bed are knitted at the same time with 1 needle and 3 needles, and the knitting is repeated until the three-dimensional convex (bulgy) is knitted. The number of knitting rows is set to be large, that is, the convex (bulgy) is significant, usually 8-12 rows;

[0007] If the three-dimensional ornament is a pattern (trimming), at the part where the pattern (trimming) is partially knitted, the loops on the two adjacent first knitting needles of the front needle bed are turned over to the same hanging knitting needle corresponding to the rear needle bed through the process setting of the electronic control board, the loops on the hanging knitting needle are idle, and the idle knitting needle 1 of the front needle bed and the idle knitting needle 2 of the rear needle bed are simultaneously knitted to form a 1-by-3 local rib structure, and the knitting is repeated. The more stitches are raised, the wider the trim is, and the more rows of knitting, the higher the trim is, until the pattern (trimming) is knitted;

[0008] Step (3): Turn over part of the loops on the rear needle bed onto the corresponding needles on the front needle bed, and continue to weave the tubular fabric at the corresponding needle positions with one needle between them until the weaving is completed.

[0009] In step (2), when weaving a three-dimensional ornament, the newly woven coil is pressed and pulled, such as by using a presser foot to press and pull the coil from top to bottom. The presser foot is driven by a presser device, and the presser foot presses and pulls the newly woven coil between the front needle bed and the rear needle bed teeth, and the knitting is repeated, and the pressing and pulling are repeated until the three-dimensional ornament is woven.

[0010] The beneficial technical effect of the present invention is that the pressing ring is used to locally press and pull the newly woven coil from top to bottom, so as to achieve smooth weaving and cloth dropping of three-dimensional ornaments, so that the tubular seamlessly formed and woven products have a variety of seamless three-dimensional effect ornaments.

[0019] The following is combined with Figure 1-5 The present invention is described in further detail.

[0020] A method for knitting a three-dimensional ornament on the outer side of a tubular knitted fabric, comprising the following steps:

[0021] refer to Figure 1 In step (1), the front and rear needle beds are spaced apart by one needle to knit a weft flat tubular fabric, wherein the needles involved in the knitting on the front and rear needle beds are the first needles 100, the needles not involved in the knitting on the front needle bed are the idle needles 1 and 200, and the needles not involved in the knitting on the rear needle bed are the loop needles 300 and the idle needles 2 and 400, and the loop needles 300 and the idle needles 2 and 400 are spaced apart by the first needles 100 of the rear needle bed.

[0022] Step (2):

[0023] If the three-dimensional ornament is convex (bulgy), refer to Figure 2 、 Figure 4 At the part where the convex shape (bulge) is to be knitted locally, the loop on the first needle 100 of the front needle bed is flipped onto the corresponding hanging needle 300 and the idle second needle 400 of the rear needle bed through the electronic control board process setting. The idle first needle 200 of the front needle bed and the idle second needle 400 of the rear needle bed are knitted at the same time with 1 needle and 3 needles, and the knitting is repeated until the three-dimensional convex shape (bulge) is knitted;

[0024] In other embodiments, if the three-dimensional ornament is a flower pattern (edge), refer to Figure 3 、 Figure 4 , in the part where the pattern (trimming) is to be knitted locally, the coils on the two adjacent first knitting needles 100 of the front needle bed are turned over to the same hanging knitting needle 300 corresponding to the rear needle bed in succession through the electronic control board process setting, the coils on the hanging knitting needle 300 are idle, and the idle knitting needle 1 200 of the front needle bed and the idle knitting needle 2 400 of the rear needle bed are simultaneously knitted with a 1-3 start, forming a 1-3 local rib structure, and knitting is repeated back and forth until the pattern (trimming) is knitted;

[0025] refer to Figure 4 In step (2), when knitting the three-dimensional ornament, a presser foot 500 driven by a presser device is used to press and pull the partially knitted loops. The presser foot 500 presses and pulls the newly knitted loops between the front and rear needle bed teeth, knitting back and forth, pressing and pulling back and forth until the three-dimensional ornament is knitted. In this embodiment, the presser device and the presser foot 500 can adopt a slide-type presser device of a computerized flat knitting machine as disclosed in the authorization announcement number CN101603238B.

[0026] Step (3): Flip the loops of the hanging needle 300 and the idle needle 2 400 on the rear needle bed in step (2) onto the first needle 100 corresponding to the front needle bed, and continue to weave the tubular fabric with one needle between the wefts until the weaving is completed.

[0027] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
