Description

Technical Field

[0001] The invention relates to the field of warp knitted fabrics and knitting methods. Background Art

[0002] The development of warp knitting technology has been continuously extended with different customer needs and different application products. For example, in recent years, the application of knitted fabrics on shoe uppers has been favored, and various knitted fabric manufacturers and developers have been continuously developing and designing warp knitted uppers. In addition to meeting the requirements of the upper molding structure, the application of the upper must also meet the requirements of the anti-fragile strength for use as the upper. In addition, there are requirements for the upper pattern. Under the premise of the first two basic requirements, the design of the upper knitting needle pattern effect is one of the main tasks that must be continuously updated and improved in normal research and development and design. Therefore, a single knitting needle effect warp knitted fabric can no longer meet the diverse needs of customers. In addition to being beautiful in appearance, the fabric must also reflect the characteristics of weaving technology and have a special structure to be more attractive. In view of this, the inventor of this case is committed to research and development, design, improvement, and testing of the pattern design and weaving method of warp knitted fabrics, which led to the creation of this case. Summary of the invention

[0003] The first object of the present invention is to provide a new type of creel jacquard warp knitted fabric, and the second object of the present invention is to provide a weaving method for the warp knitted fabric of the first object. The warp knitted fabric woven by the weaving method can achieve different pattern effects on both sides, specifically, stripes are formed on one side and holes corresponding to the stripes can be partially provided, and the other side can achieve a jacquard effect according to the design. According to the selection of yarn, the fabric can be further made more visually beautiful.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a new type of yarn frame jacquard warp knitted fabric, which is woven by a warp knitting machine and comprises a surface layer, a connecting layer and a back layer, wherein the surface layer is woven by surface comb yarns, and the back layer is woven by back comb yarns and jacquard yarns, and the connecting layer is woven and connected between the surface layer and the back layer, and a jacquard structure is formed by weaving jacquard tissue on the surface layer with jacquard yarns, and the back layer is formed with a stripe structure having the same warp direction as the weaving, and the stripe structure is a stripe structure in which two adjacent weaving columns are indented a distance to form a combined column in a plurality of parallel connected weaving columns, and the two combined columns are connected by a jacquard yarn warp knitting, and the weaving columns in the combined column are all connected by two back comb yarns and a jacquard yarn warp knitting, and a hole structure is formed locally on the back layer between the corresponding two combined columns.

[0005] The surface comb yarn woven by the surface layer adopts transparent fish silk thread.

[0006] The back comb yarn and / or jacquard yarn woven in the back layer is made of colored yarn, colorable yarn and / or non-colorable yarn.

[0007] The above-mentioned novel weaving method of creel jacquard warp knitted fabric,

[0008] The needle bed of the warp knitting machine is a double needle bed warp knitting machine including a rear needle bed and a front needle bed;

[0009] The comb bars on the comb bar traverse mechanism of the warp knitting machine are divided into a first back comb bar, a second back comb bar, a jacquard comb bar and a plurality of surface comb bars in sequence from the rear needle bed to the front needle bed;

[0010] The knitting needles of the rear needle bed knit the warp yarns on the first back comb bar, the second back comb bar and the jacquard comb bar to form the fabric structure of the back layer, and the knitting needles of the front needle bed knit the warp yarns on the jacquard comb bar and a plurality of surface comb bars to form the fabric structure of the surface layer;

[0011] The warp yarns threaded on the guide needles of the first back comb bar and the second back comb bar are the yarns of the disc head on the warp knitting machine on the side corresponding to the rear needle bed, the warp yarns threaded on the guide needles of the jacquard comb bar are the yarns on the creel configured for the warp knitting machine, and the warp yarns threaded on the guide needles on the surface comb bar are the yarns of the disc head on the warp knitting machine on the side corresponding to the front needle bed;

[0012] The yarn guide needles on the first back comb bar thread the yarn in a way of one warp needle and one empty needle, the yarn guide needles on the second back comb bar and the jacquard comb bar thread the yarn in a full needle manner, and the yarn guide needles on the surface comb bar thread the yarn according to the surface layer weaving structure design;

[0013] During warp knitting, the warp knitting machine performs knitting according to the warp knitting machine working program of the fabric structure of the corresponding new creel jacquard warp knitted fabric;

[0014] The comb bar transverse movement mechanism drives the transverse movement of the first back comb bar and the jacquard comb bar as a way of transversely moving one needle position to perform a reciprocating transverse movement, and the comb bar transverse movement mechanism drives the transverse movement of the second back comb bar as a way of not moving the needle position of the adjacent knitting needle on the corresponding rear needle bed, but only reciprocating transverse movement on both sides of a knitting needle on the corresponding rear needle bed, and the reciprocating transverse movement of the first back comb bar and the jacquard comb bar is performed in the opposite direction to form a striped structure of the back layer; when the warp knitting work corresponds to the position of the hole structure, the corresponding jacquard comb bar The yarn guide needles on the jacquard comb bar are skewed so that the warp yarns on the yarn guide needles with the skewed needle action are padded onto the adjacent rear needle bed needles in the skewed direction and cannot be padded onto the originally corresponding rear needle bed needles, thereby weaving a hole structure; when the warp knitting work corresponds to the position of the jacquard structure of the surface layer, the reciprocating lateral movement of the jacquard comb bar and the surface comb bar and the skewed needle action of the yarn guide needles of the jacquard comb bar are driven by the comb bar transverse movement mechanism, so that the warp yarns on the yarn guide needles with the skewed needle action and the corresponding surface comb bar can be padded onto the corresponding front needle bed needles, thereby realizing the jacquard structure and forming a connecting layer structure.

[0015] By adopting the above technical scheme, the beneficial effect of the present invention is that the back layer of the warp knitted fabric of the above structure woven by the above method is woven on the basis of the basic weaving to form a locally designed hole structure, and the surface layer is woven on the basis of the basic weaving to form a jacquard pattern. The woven fabric products with this warp knitted fabric structure have no structural design in the existing products. Because of the limitation of the warp knitting method, the patterns reflected on the woven fabric by the existing warp knitting method can only be regular. For example, the warp knitted mesh cloth has a regular mesh distribution on the whole surface, and will not form a structure different from the mesh in the local weaving. The purpose of the present invention is to achieve the effect of different flower patterns on both sides, and the different flower patterns on both sides are specifically that stripes are formed on one side and holes corresponding to the stripes are locally arranged, and the jacquard effect can be achieved on the other side according to the design. Here, the formation of the structure of the side with stripes formed and local holes arranged is the innovative improvement of the fabric structure. In addition, according to the above-mentioned further selection of yarn, the surface layer adopts transparent fish silk thread and the back layer can adopt a combination of colored yarn or colorable yarn, so that the woven fabric can achieve the texture structure and color of the back layer in contrast, and the fabric effect is further more visually beautiful and more novel. The design of the striped structure woven by such a method is combined with the jacquard comb bias needle to realize the formation of a hole structure in any part, which solves the problem that in other woven structure structures, it is impossible to form a hole structure in any part between the stripes when there is a striped structure on one side and at the same time form different jacquard effects on the other side according to different designs, thereby developing a new warp knitted fabric with a novel structure and beautiful appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of the back layer structure of a novel creel jacquard warp knitted fabric according to the present invention;

[0017] Figure 2 The invention discloses a schematic diagram of the surface layer structure of a novel creel jacquard warp knitted fabric. DETAILED DESCRIPTION

[0018] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0019] The invention discloses a novel warp knitted fabric made of jacquard creel, which is knitted by a warp knitting machine. Figure 1 and Figure 2 As shown, its structure includes a surface layer 1, a connecting layer (not visible in the figure) and a back layer 3, the surface layer 1 is woven by surface comb yarn to form a base layer, the back layer 3 is woven by back comb yarn and jacquard yarn to form a base layer, the surface comb yarn, back comb yarn and jacquard yarn here refer to yarns guided by guide needles on different combs, the connecting layer is woven and connected between the surface layer 1 and the back layer 3, and the jacquard structure 11 is woven by jacquard yarn on the surface layer 1 to form a structure, it can be seen here that the surface layer 1 is woven by surface comb yarn to form a base layer, and the jacquard effect is further woven on the base layer by jacquard yarn.

[0020] The back layer 3 is formed with a striped structure 31 that is the same as the weaving warp direction. Note that the striped direction of the striped structure is consistent with the direction of the weaving warp direction. Usually, the weaving discharge of the warp knitting machine is vertical. The striped direction is one of the important structures that the weaving method of the warp knitted fabric of the present invention can realize the following hole structure. The striped structure 31 is formed by indenting two adjacent weaving columns 32 in a plurality of weaving columns 32 connected side by side to form a combined column 33. The two combined columns 33 are connected by a jacquard yarn warp knitting. The weaving columns 32 in the combined column 33 are all connected by two back comb yarns and a jacquard yarn warp knitting, so that the effect of indenting two weaving columns 32 is achieved, reflecting a more obvious striped structure. A hole structure 34 is formed locally on the back layer 3 between the corresponding two combined columns 33. The hole structure 34 can be formed at any position between each two combined columns 33 in the back layer 3, and is specifically arranged according to the needs of the fabric organization structure design. For example, the warp knitted fabric shown in the figure is applied to a shoe upper product, and its hole structure 34 design has the effect of heat dissipation and ventilation.

[0021] In addition, in the present invention, the surface comb yarn woven by the surface layer 1 can be woven with transparent fish silk thread, and the woven surface layer 1 is a transparent layer, which can contrast the stripe structure 31 and hole structure 34 of the back layer 3, reflecting a hazy texture effect. In addition, the back comb yarn and / or jacquard yarn woven by the back layer 3 can be colored yarn, colorable yarn and / or non-colorable yarn. The finished product can achieve different effects through the selection of yarn. For example, one option is that the jacquard yarn is selected as colorable yarn, and the back comb yarn is selected in whole or in part as colorable yarn. After the weaving is completed, the colorable yarn is colored through the dyeing process. The finished product has the effect of colored jacquard structure 11 when viewed from the surface layer 1. In addition, the color and texture effect of the back layer 3 are contrasted, and the visual effect of the fabric is more novel and more amazing.

[0022] The following specifically discloses a knitting method of a novel creel jacquard warp knitted fabric of the above-mentioned organizational structure of the present invention.

[0023] The needle bed of the warp knitting machine is a double needle bed warp knitting machine including a rear needle bed and a front needle bed, so that a multi-layer structure fabric can be woven;

[0024] The combing bars on the combing bar transverse movement mechanism of the warp knitting machine are divided into a first back combing bar, a second back combing bar, a jacquard combing bar and a plurality of surface combing bars in the direction from the rear needle bed to the front needle bed. In this embodiment, since the specific weaving structure of the surface layer 1 is not limited, a plurality of surface combing bars are used according to design requirements, and the number is not specifically limited, which does not affect the technical personnel in this field to clearly understand the technical solution of the present invention. It is explained here that the number of combing bars on the combing bar transverse movement mechanism is arranged according to the design of the fabric structure. For example, if a thicker fabric with higher structural strength is required, a plurality of combing bars can be used for weaving. For example, if it is used for shoe uppers, the strength requirements of the fabric must meet the strength, wear resistance and other standards of the shoe upper products.

[0025] The knitting needles of the rear needle bed knit the warp yarns on the first back comb bar, the second back comb bar and the jacquard comb bar to form the fabric structure of the back layer 3, and the knitting needles of the front needle bed knit the warp yarns on the jacquard comb bar and multiple surface comb bars to form the fabric structure of the surface layer 1; because the comb bar transverse movement mechanism of the warp knitting machine not only drives the comb bar transverse movement but also drives all the comb bars to swing synchronously, and the swinging direction is perpendicular to the transverse movement direction, double-layer warp knitted fabrics can be achieved. These are the basic knowledge of warp knitting machinery, and the basic knowledge of warp knitting machines will not be described in more detail here.

[0026] The warp yarns passed through the guide needles of the first back combing bar and the second back combing bar are the yarns of the disk heads on the warp knitting machine on the side corresponding to the rear needle bed, the warp yarns passed through the guide needles of the jacquard combing bar are the yarns on the yarn frame configured for the warp knitting machine, and the warp yarns passed through the guide needles on the surface combing bar are the yarns of the disk heads on the warp knitting machine on the side corresponding to the front needle bed; the yarns on the disk heads are conveyed at the same synchronous speed, while the yarns on the yarn frame can be flexibly output according to needs, and the yarns on the yarn frame are passed through the jacquard combing bar to realize the different yarn conveying requirements of the guide needles on the jacquard combing bar at the back, such as the yarn lifting holes in the back layer 3 and the jacquard structure 11 in the surface layer 1.

[0027] The guide needles on the first back comb bar thread the yarn in a manner of one needle threading the warp yarn and one empty needle, and the guide needles on the second back comb bar and the jacquard comb bar thread the yarn in a full needle manner, that is, all the guide needles are threaded with yarn. In addition, the guide needles on each surface comb bar thread the yarn according to the weaving structure design of the surface layer 1. Since the specific weaving structure of the surface layer 1 is not limited in the present invention, the threading method of the guide needles of the surface comb bar corresponding to the woven surface layer 1 is not specifically limited, which does not affect the technical personnel in this field to clearly understand the technical solution of the present invention.

[0028] The improvement of the knitting method of the present invention mainly lies in the knitting method on the back layer, and the knitting method of the back layer is mainly described below; during the warp knitting operation, the warp knitting machine performs the knitting operation according to the warp knitting machine operation program of the fabric structure of the corresponding new creel jacquard warp knitting fabric;

[0029] Among them, the comb bar transverse movement mechanism drives the transverse movement of the first back comb bar and the jacquard comb bar as a way of transverse movement of one needle position to perform reciprocating transverse movement, and the comb bar transverse movement mechanism drives the transverse movement of the second back comb bar as a way of not moving the needle position of the adjacent knitting needle beyond a knitting needle on the corresponding rear needle bed, but only reciprocating transverse movement on both sides of a knitting needle on the corresponding rear needle bed, and the reciprocating transverse movement of the first back comb bar and the jacquard comb bar is performed in the opposite direction to form a striped structure of the back layer 3 and the striped texture of the structure is a clear stripe that is closer to a straight line, which is different from the stripes of other existing organizational structures. Because in the existing warp knitting technology, most of the striped effects are slightly Point distortion is not in the form of straight lines, and this problem can be solved by the transverse shifting method described above; when the warp knitting work corresponds to the position of the hole structure 34, the guide needles on the corresponding jacquard comb bar are deflected, so that the warp yarns on the guide needles of the deflected action are padded on the adjacent rear needle bed needles in the deflected direction and cannot be padded on the original corresponding rear needle bed needles, thereby weaving a hole structure; when the warp knitting work corresponds to the position of the jacquard structure 11 of the surface layer 1, the jacquard comb bar and the surface comb bar are driven by the reciprocating transverse movement of the jacquard comb bar and the deflected action of the guide needles of the jacquard comb bar, so that the warp yarns on the guide needles of the deflected action and the corresponding surface comb bar can be padded on the corresponding front needle bed needles, thereby realizing the jacquard structure 11 and the structure of the connecting layer.

[0030] The threading method of the guide needles on the above-mentioned first back comb bar, second back comb bar and jacquard comb bar and the lateral movement method of the comb bar transverse movement mechanism to drive the first back comb bar, second back comb bar and jacquard comb bar are important improvements in the method of forming the weaving structure of the back layer 3 and realizing the ability to weave a hole structure 34 at any local position between the corresponding two combination arrays 33. It is also through this improvement that the problem that in other weaving structure structures, it is impossible to form a hole structure at any local position between the stripes when there is a striped structure on one side and to form different jacquard effects on the other side according to different designs is solved.

[0031] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
