Abstract
Description
Technical Field
[0001] This invention relates to the field of single-sided weft knitting machines, and more particularly to a method for a single-sided weft knitting machine to simulate the knitting effect of a double-sided transfer knitting machine. Background Technology
[0002] In the current domestic and international textile industry, double-sided transfer knitting machines are generally used in sportswear, which have a distinct textured surface. However, due to technical limitations, their gauges are generally around 22 gauges, and the machines have relatively low production efficiency. Therefore, the high-end, non-spandex varieties that are popular in the market are generally limited in their application value. In order to explore new technologies and methods to improve the competitiveness of products, it is necessary to further develop products with mesh structures to resemble double-sided knitting machines based on single-sided weft knitting mesh machines. Summary of the Invention
[0003] The purpose of this invention is to overcome the above-mentioned problems in the prior art and to provide a method for a single-sided weft knitting machine to simulate the knitting effect of a double-sided transfer knitting machine.
[0004] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:
[0005] A method for simulating the knitting effect of a double-sided transfer knitting machine using a single-sided weft knitting machine includes:
[0006] (1) The triangle of the 36-needle single-sided weft knitting machine has loop needle path, floating needle path and tuck needle path in the ground yarn of the triangle, and has tuck needle path and floating needle path in the jacquard yarn of the triangle.
[0007] (2) Replace the small needles on the 36-needle single-sided weft knitting machine with large needles;
[0008] (3) Set up an electromagnetic needle selector, so that the ground yarn electromagnet A and ground yarn electromagnet B of the electromagnetic needle selector are located below the ground yarn needle movement triangle area of the triangle, and the jacquard yarn electromagnet A and jacquard yarn electromagnet B of the electromagnetic needle selector are located in the jacquard yarn needle movement triangle area of the triangle. Set the electromagnetic needle selector to switch between three positions when the needle passes through the ground yarn position and to switch between two positions when the needle passes through the jacquard yarn and spandex positions.
[0009] (4) Design a material combination scheme for ground yarn, jacquard yarn and spandex;
[0010] (5) Set the process parameters for a 36-needle single-sided weft knitting machine.
[0011] The material combination scheme is as follows: the ground yarn uses 50D~100D matte elastic yarn, the jacquard yarn uses 20D~75D semi-dull elastic yarn, and 30D~40D spandex.
[0012] The material combination scheme is as follows: the ground yarn uses 50D~100D matte elastic yarn, the jacquard yarn uses 20D~75D matte elastic yarn, and 30D~40D spandex.
[0013] The material combination scheme is as follows: the ground yarn uses 30D~50D bright elastic yarn, the jacquard yarn uses 40D~150D semi-bright elastic yarn, and 30D~40D spandex.
[0014] The material combination scheme is as follows: the ground yarn uses 30D~50D bright elastic yarn, the jacquard yarn uses 40D~150D dull elastic yarn, and 30D~40D spandex.
[0015] The process parameters of the single-sided weft knitting machine are divided into four groups, which are respectively defined as green process, white process, red process and blue process according to the color definition in the Procad software.
[0016] The green process is as follows: When the knitting needle enters the ground yarn needle track triangle area, ground yarn electromagnets A and B are not working. Under the action of the jacquard plate, the knitting needle moves along the looping needle track of the ground yarn needle track triangle area, hooking the ground yarn to form a looping ground yarn coil. Then, while maintaining the hooked ground yarn state, the knitting needle enters the jacquard yarn needle track triangle area. Jacquard yarn electromagnets A and B are not working. Under the action of the jacquard plate, the knitting needle moves along the looping needle track of the jacquard yarn needle track triangle area, hooking the jacquard yarn and spandex. The jacquard yarn covers the ground yarn to form a matte plain weave effect.
[0017] The white process is as follows: When the knitting needle enters the ground yarn needle track triangle area, neither ground yarn electromagnet A nor ground yarn electromagnet B works. Under the action of the jacquard plate, the knitting needle moves along the looped needle track of the ground yarn needle track triangle area, hooking the ground yarn to form a looped ground yarn loop. Then, while maintaining the hooked ground yarn state, the knitting needle enters the jacquard yarn needle track triangle area. Both jacquard yarn electromagnets A and B work to attract the knitting needle, which moves along the floating needle track of the jacquard yarn needle track triangle area. The knitting needle does not hook the jacquard yarn and spandex, forming a mesh effect with only ground yarn loops and the jacquard yarn and spandex floating behind the ground yarn loops.
[0018] The red process is as follows: When the knitting needle enters the ground yarn needle track triangle area, ground yarn electromagnet A is not working, while ground yarn electromagnet B is working. Under the synergistic effect of the jacquard piece and ground yarn electromagnet B, the knitting needle moves along the looping needle track of the ground yarn needle track triangle area, hooking the ground yarn to form a ground yarn loop. Then, while maintaining the hooked ground yarn state, the knitting needle enters the jacquard yarn needle track triangle area. Neither jacquard yarn electromagnet A nor jacquard yarn electromagnet B is working, and the knitting needle moves along the looping needle track of the jacquard yarn needle track triangle area, hooking the jacquard yarn and spandex to form a mixed yarn large loop with two ground yarns, two jacquard yarns, and two spandex.
[0019] The blue process is as follows: When the knitting needle enters the ground yarn needle track triangle area, ground yarn electromagnet A is not working, while ground yarn electromagnet B is working. Under the synergistic effect of the jacquard piece and ground yarn electromagnet B, the knitting needle moves along the looping needle track of the ground yarn needle track triangle area, hooking the ground yarn and forming a ground yarn loop. Then, while maintaining the state of hooking the ground yarn, the knitting needle enters the jacquard yarn needle track triangle area, where both jacquard yarn electromagnets A and B are working. The knitting needle is attracted by jacquard yarn electromagnets A and B, and the knitting needle does not hook the jacquard yarn and spandex, forming a single large ground yarn loop with two ground yarns but no jacquard yarn or spandex.
[0020] The beneficial effects of this invention are as follows: Based on the existing 36-needle single-sided weft knitting machine, the cam is modified, the knitting needles are replaced, an electromagnetic needle selector is set, a material matching scheme is designed, and the process parameters of the single-sided weft knitting machine are set to achieve the transfer effect of the double-sided transfer machine. Moreover, the transfer effect is prominent on the front side of the fabric, and the transfer effect can be freely jacquard. Using a 36-needle single-sided weft knitting machine, high-density knitted fabrics can be produced. The machine has more rows, the number of working rows is not reduced, and the machine speed is faster, which greatly improves the knitting efficiency. Compared with double-sided machines, the cost of fabric is greatly reduced. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] like Figures 1 to 6 As shown, a method for simulating the knitting effect of a double-sided transfer knitting machine using a single-sided weft knitting machine includes:
[0031] (1) Triangle 5 of a 36-needle single-sided weft knitting machine, so that the ground yarn of triangle 5 has loop needle path, floating needle path and tuck needle path, so that the jacquard yarn of triangle 5 has tuck needle path and floating needle path.
[0032] (2) Replace the small needles on the 36-needle single-sided weft knitting machine with large needles 6;
[0033] (3) Set up an electromagnetic needle selector, so that the ground yarn electromagnet A1 and ground yarn electromagnet B2 of the electromagnetic needle selector are located below the ground yarn needle movement triangle area of the triangle, and the jacquard yarn electromagnet A3 and jacquard yarn electromagnet B4 of the electromagnetic needle selector are located in the jacquard yarn needle movement triangle area of the triangle. Set the electromagnetic needle selector to switch between three positions when the needle passes through the ground yarn position and to switch between two positions when the needle passes through the jacquard yarn and spandex positions.
[0034] (4) Design a material combination scheme for ground yarn, jacquard yarn and spandex;
[0035] (5) Set the process parameters for a 36-needle single-sided weft knitting machine.
[0036] The process parameters of the single-sided weft knitting machine are divided into four groups, which are respectively defined by the color in the Procad software as green process, white process, red process, and blue process.
[0037] Green processes include: such as Figure 1 The diagram shows the movement trajectory of the knitting needle on the triangle. When the needle enters the ground yarn needle track triangle, neither ground yarn electromagnets A nor B are activated. Under the action of the jacquard plate, the needle moves along the looped needle path in the ground yarn needle track triangle, hooking the ground yarn to form a looped ground yarn. Then, while still hooking the ground yarn, the needle enters the jacquard yarn needle track triangle. Neither jacquard yarn electromagnets A nor B are activated. Under the action of the jacquard plate, the needle moves along the tufted needle path in the jacquard yarn needle track triangle, hooking the jacquard yarn and spandex. The jacquard yarn covers the ground yarn to form a matte plain weave effect.
[0038] White finish is: such as Figure 2The movement trajectory of the needle on the triangle is shown. When the needle enters the ground yarn needle track triangle area, neither ground yarn electromagnet A nor ground yarn electromagnet B works. Under the action of the jacquard plate, the needle moves along the loop needle track of the ground yarn needle track triangle area, hooking the ground yarn and forming a loop ground yarn loop. Then, while keeping the ground yarn hooked, the needle enters the jacquard yarn needle track triangle area. Both jacquard yarn electromagnets A and B work to attract the needle. The needle moves along the floating needle track of the jacquard yarn needle track triangle area. The needle does not hook the jacquard yarn and spandex, forming a mesh effect with only ground yarn loops and the jacquard yarn and spandex floating behind the ground yarn loops.
[0039] The red process is as follows: Figure 3 The diagram shows the movement trajectory of the needle on the triangle. When the needle enters the ground yarn needle track triangle, ground yarn electromagnet A is not working, while ground yarn electromagnet B is working. Under the synergistic effect of the jacquard piece and ground yarn electromagnet B, the needle moves along the looping needle path of the ground yarn needle track triangle, hooking the ground yarn to form a ground yarn loop. Then, while maintaining the hook on the ground yarn, the needle enters the jacquard yarn needle track triangle. Neither jacquard yarn electromagnet A nor jacquard yarn electromagnet B is working, and the needle moves along the looping needle path of the jacquard yarn needle track triangle, hooking the jacquard yarn and spandex to form a mixed yarn large loop with two ground yarns, two jacquard yarns, and two spandex.
[0040] The blue finish is: (e.g., ...) Figure 4 The movement trajectory of the needle on the triangle is shown. When the needle enters the ground yarn needle track triangle area, ground yarn electromagnet A is not working, while ground yarn electromagnet B is working. Under the synergistic effect of the jacquard piece and ground yarn electromagnet B, the needle moves along the looping needle track of the ground yarn needle track triangle area. The needle hooks the ground yarn, forming a ground yarn loop. Then, while maintaining the hook on the ground yarn, the needle enters the jacquard yarn needle track triangle area. Both jacquard yarn electromagnets A and B are working, and the needle is attracted by them. The needle does not hook the jacquard yarn or spandex, forming a single large ground yarn loop with two ground yarns but no jacquard yarn or spandex.
[0041] To emphasize the strong striped weave effect, the material combination scheme is as follows: the ground yarn uses 50D~100D matte elastic yarn, the jacquard yarn uses 20D~75D semi-dull elastic yarn, and 30D~40D spandex; or the material combination scheme is as follows: the ground yarn uses 50D~100D matte elastic yarn, the jacquard yarn uses 20D~75D matte elastic yarn, and 30D~40D spandex.
[0042] To highlight the striped weakness in the weave, the material combination scheme is as follows: the ground yarn uses 30D~50D bright elastic yarn, the jacquard yarn uses 40D~150D semi-dull elastic yarn, and 30D~40D spandex; or the material combination scheme is as follows: the ground yarn uses 30D~50D bright elastic yarn, the jacquard yarn uses 40D~150D matte elastic yarn, and 30D~40D spandex.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
