Description

Technical Field

[0001] The invention relates to the technical field of fabrics, in particular to a weaving method for a warp knitted fabric with double needle bed light and dark patterns and open and closed meshes alternately arranged. Background Art

[0002] At present, the double needle bed warp knitted fabrics on the warp knitted fabric market, commonly known as sandwich fabrics, have a variety of patterns, but most of them are visual changes of yin and yang (light and dark) of a pattern, that is, either a light pattern or a dark pattern. One of the disadvantages of this kind of fabric is the single pattern change. The second disadvantage is that most fabrics have a dense and flat surface, lack of concave and convex and mesh effects, low air permeability, poor moisture dissipation, and low drying rate. Obviously, these fabrics cannot meet the market demand for double needle bed warp knitted fabrics with diverse patterns and powerful comfort functions. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a weaving method for a warp knitted fabric with a double needle bed light and dark pattern and an open and closed mesh alternately arranged. The weaving method of the present application obtains both a light pattern and a dark pattern, and the light and dark patterns are alternately arranged in an orderly manner, the dark pattern has a light pattern, and the light pattern has a dark pattern. At the same time, the fabric surface is designed with open and closed visual holes (open visual holes and closed visual holes), and the open and closed visual holes make the fabric surface uneven, the fabric pattern has light and dark, high and low, showing the three-dimensional effect of the light and dark pattern and the open and closed visual holes alternately arranged. When the fabric is moved and observed, the fabric pattern changes alternately between light and dark, and the concave and convex are staggered, with a significant sense of changing pattern, changing light and dark, and changing three-dimensional effect. At the same time, the open and closed visual holes (open visual holes and closed visual holes) improve the permeability of the fabric, increase the air permeability, accelerate the moisture dissipation, improve the dryness, and enhance the comfort.

[0021] Reference Figures 1 to 12 The embodiment of the present invention provides a weaving method for a warp knitted fabric with alternating configurations of light and dark patterns and open and closed meshes on a double needle bed, the fabric is woven by a double needle bed double jacquard warp knitting machine, the ground comb bar GB1 of the front needle bed is programmed to weave a base surface layer 100, the base surface layer 100 is not transparent, the ground comb bars GB5 and GB6 of the rear needle bed are programmed to weave an observation surface layer with a transparent structure, and the transparent structure of the observation surface layer is a visible hole formed by the ground comb bars GB5 and GB6 of the rear needle bed in a warp threading manner; The base surface layer 100 and the observation surface layer 200 are fixedly connected by a jacquard structure. The jacquard structure is formed by the front jacquard bar JB3-1 / JB3-2 jacquard-ing the base surface layer 100 and the observation surface layer 200 back and forth. There are at least two types of jacquard structures. The two types of jacquard structures are arranged on both sides of the visible hole and are arranged opposite to each other.

[0022] Specifically, the base surface layer 100 is a plain weave.

[0023] Specifically, Figure 2 A schematic diagram of the layout of the double-needle-bed double-jacquard warp knitting machine's comb bars is provided. Among them, the front jacquard comb bars include JB3-1 and JB3-2, and the rear jacquard comb bars include JB4- and JB4-2. The needle alignment method is specifically shown in the figure, the front jacquard JB3-2 is aligned and overlapped with JB3-1, and the rear jacquard JB4-2 is aligned and overlapped with JB4-1. During the weaving process, the needle positions of JB3-2 and JB3-1, and JB4-2 and JB4-1 are corresponding, and they are woven at the same time and in the same position, so that a complex jacquard pattern can be formed. In addition, this needle alignment method ensures that the front and rear jacquard comb bars can work together to form the desired light and dark patterns and open and closed mesh effects on the warp knitted fabric.

[0024] According to some embodiments of the present application, the jacquard weave includes a first jacquard weave 300 and a second jacquard weave 400, and one end of the first jacquard weave 300 and the second jacquard weave 400 extends to the inner wall of the viewing hole 210. Specifically, the front jacquard bar JB3-1 / JB3-2 uses different weaves to jacquard the base surface layer 100 and the observation surface layer 200 back and forth to form the first jacquard weave 300 and the second jacquard weave 400 respectively, and the first jacquard weave 300 and the second jacquard weave 400 are deep on the left and shallow on the right, or shallow on the left and deep on the right.

[0025] For example, when the jacquard bar JB3-1 structure is 1-0-0-0 / 0-1-1-1 / / , the left side of the visible hole 210 of the surface layer 200 is jacquard, and the left side shows a dark effect; when the structure of JB3-2 is 2-1-1-1 / 1-2-2-2 / / , the right side of the visible hole 210 of the surface layer 200 is jacquard, and the right side shows a light effect. That is, at this time, the first jacquard structure 300 is dark, and the second jacquard structure 400 is light.

[0026] On the contrary, when the jacquard bar JB3-1 is in the structure of 2-1-1-1 / 1-2-2-2 / / , the jacquard is formed on the right side of the visible hole 210 of the surface layer 200, and the left side shows a light color effect; when the jacquard is formed on the right side of the visible hole 210 of the surface layer 200, the jacquard is formed on the right side of the visible hole 210 of the surface layer, and the right side shows a dark color effect. That is, at this time, the first jacquard structure 300 is light-colored, and the second jacquard structure 400 is dark-colored.

[0027] According to some embodiments of the present application, the ground comb GB5 of the rear needle bed is: 5-5-1-0 / 0-0-2-3 / 3-3-1-0 / 0-0-2-3 / 3-3-1-0 / 0-0-4-5 / / , and the threading method is 2 threadings and 2 empty threads; the ground comb GB6 is: 0-0-4-5 / 5-5-3-2 / 2-2-4-5 / 5-5-3-2 / 2-2-4-5 / 5-5-1-0 / / / , and the threading method is 1 threading, 2 empty threads and 1 threading. By utilizing changes in the organization and the changes in the threading method, the observation surface layer 200 forms a checkered bottom net organization, and the mesh of the checkered bottom net is a visible hole 210.

[0028] Furthermore, the observation surface layer 200 has a viewing hole 210 and a closed portion 220 .

[0029] Among them, the rear jacquard bar JB4-1 / JB4-2 forms a weft insertion structure 500 in part of the visible holes 210 of the observation surface layer 200. Specifically, when the structure of the rear jacquard bar JB4-1 / JB4-2 is 0-0-0-0 / 0-0-2-2 / / , the weft insertion structure 500 fills part of the visible holes 210 to form a closed portion 220.

[0030] like Figure 6 , Figure 7 As shown, the fabric obtained by the weaving method of the present application has two patterns, light and dark, and the light and dark patterns are alternately arranged in an orderly manner, that is, there are light patterns in the dark patterns and dark patterns in the light patterns.

[0031] At the same time, the fabric surface is designed with many open and closed meshes (open meshes and closed meshes). The open and closed meshes make the fabric surface uneven, and the light and dark patterns of the fabric make the real object have a three-dimensional effect. When people move and observe the fabric, the light and dark patterns of the fabric change alternately, and the unevenness is staggered, with a significant visual change of pattern. The light and dark changes of the pattern make the fabric pattern visually have a three-dimensional effect. Furthermore, the open and closed meshes (open meshes and closed meshes) increase the permeability of the fabric, increase the breathability, accelerate the moisture dissipation, improve the drying performance, and enhance the comfort of the fabric.

[0032] Specifically, please refer to Fig.12 In the specific embodiment provided, when people look at the fabric from different viewing angles, it can be clearly seen that the pattern of the fabric seen from different directions has light and dark changes, and the surface of the fabric shows a concave and convex effect due to the weft insertion structure, and the closed portion 220 forms other patterns under the control of the weaving program, and the pattern presents a three-dimensional visual effect. The light and dark patterns are combined with the changes in the three-dimensional pattern, so that the fabric presents an effect of superimposed changes of multiple patterns when viewed from different directions.

[0033] According to some embodiments of the present application, the yarns of the jacquard guide bar in front of the double needle bed are two different yarns: cationic dyeable polyester DTY and polyester DTY.

[0034] According to some embodiments of the present application, the double-needle-bar-rear-jacquard-bar yarn is a cationic-dyeable polyester DTY yarn.

[0035] According to some embodiments of the present application, the yarns of the double needle bar rear needle bar ground combs GB5 and GB6 are black polyester FDY dyed yarns.
