Description

Technical Field

[0001] The invention relates to the field of knitted fabrics, in particular to a multi-layer undulating high-low-layer high-air-layer sandwich jacquard fabric and a knitting method thereof. Background Art

[0002] As consumers' requirements for footwear and clothing products continue to increase, the fabric organization design has also gradually developed from flat design to three-dimensional design. At present, there are mainly two types of three-dimensional pattern fabrics for weft knitted fabrics: the first type is formed by the base fabric hanging needle, that is, the number of weaving paths of the fabric in the raised area is greater than the number of weaving paths of the bottom layer, so as to form a three-dimensional pattern with a raised shape on the surface layer, but the width of this type of three-dimensional pattern is relatively limited. If the pattern width is large, the three-dimensional sense and fullness of the pattern are poor. If the pattern width is too small, it will affect the pattern design type, and the formed pattern will be more rigid and have a poor hand feel; the second type is to weave a channel between the surface layer and the bottom layer, and form a three-dimensional pattern by filling the weaving thread / floating thread. The fullness of the three-dimensional pattern formed is greatly affected by the distribution of the weaving thread / floating thread. The pattern in the area with more weaving thread / floating thread distribution is fuller, and the pattern in the area with less weaving thread / floating thread distribution is flatter. The fullness of the pattern is difficult to control, and the pattern size is limited. If the pattern is too large, it will affect the overall stability of the fabric. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] A multi-layer undulating high-low-high-air-layer sandwich jacquard fabric, such as Figure 1-2 As shown, the fabric is woven as a whole, and the fabric is woven as a whole, including a first woven area 1 and a second woven area 2; the height of the second woven area 2 is greater than that of the first woven area 1, the first woven area 1 includes a first surface layer 11 and a first bottom layer 12, and the second woven area 2 includes a second surface layer 21, a first middle layer 23 and a second bottom layer 22;

[0041] The braided yarns include a second yarn, a third yarn and a fourth yarn, wherein the third yarn includes at least one elastic yarn, and the first yarn is an elastic yarn;

[0042] The second yarn, the elastic yarn in the third yarn and the fourth yarn together form the first bottom layer 12, and the remaining third yarns form the first surface layer 11; all the third yarns form the second surface layer 21, the second yarn connects the second surface layer 21 and the second bottom layer 22 in an up and down loop manner to form a first middle layer 23, and the fourth yarn forms the second bottom layer 22.

[0043] In this embodiment, at the junction area between the first knitting area 1 and the second knitting area 2 , the second yarn is knitted with a tuck stitch and a loop stitch and the elastic yarn in the third yarn is fixed to the first bottom layer 12 .

[0044] In this embodiment, the second yarn forms a spacer knitting structure on the first bottom layer 12 .

[0045] In this embodiment, the second yarn forms an upper and lower tuck structure with spaced needles or full needles in the first intermediate layer 23. When it is a spaced needle tuck structure, the pattern formed is softer, and when it is a full needle tuck structure, the pattern formed has good resilience and stiffness.

[0046] As a preferred embodiment of the present invention, the second yarn is a monofilament, which has a relatively large rigidity and can form a pattern with a strong three-dimensional sense and a fuller pattern.

[0047] As a preferred embodiment of this embodiment, the second yarn includes two types of yarns woven alternately, namely, monofilament and multifilament, and due to the different rigidities of the monofilament and multifilament, a three-dimensional pattern with a concave-convex effect on the surface is formed after being shaped.

[0048] As a preferred mode of this embodiment, the first yarn is a spandex core-spun yarn. After shaping, the first yarn shrinks and hides the surface loops of the second yarn, thereby making the texture of the fabric tight and the color of the fabric clean.

[0049] As a preferred embodiment of the present invention, the fabric is woven by a circular weft knitting machine.

[0050] In this embodiment, the shape of the second weaving area 2 can be set according to the design, and its shape and size are not limited.

[0051] The multi-layer undulating high-low-layer high-air-layer sandwich jacquard fabric of this embodiment is obtained by the following weaving method:

[0052] The knitting method comprises: selecting a second yarn, a third yarn and a fourth yarn for knitting, wherein the third yarn comprises at least one elastic yarn;

[0053] (1) Weaving the first weaving area 1: using the second yarn, the elastic yarn in the third yarn and the fourth yarn to weave to form its first bottom layer 12; using the remaining third yarn to weave to form the first surface layer 11;

[0054] (2) Weaving junction area: the second yarn is used to weave the adjacent tuck stitch and loop forming stitch on the first bottom layer 12, and at the same time, the second yarn of the tuck stitch and loop forming part of the bottom layer fixes the tuck stitch of the elastic yarn in the third yarn to the bottom layer;

[0055] (3) Weaving the second weaving area 2: using all the third yarns to weave the second surface layer 21, using the first yarn and the fourth yarn to weave the second bottom layer 22, and using the second yarn to form a first intermediate layer 23 by tucking the second surface layer 21 and the second bottom layer 22;

[0056] (4) Weaving junction area: The second yarn is used to weave the adjacent tuck stitch and loop stitch on the bottom layer and the elastic yarn in the third yarn is fixed to the first bottom layer 12.

[0057] After weaving, the fabric needs to undergo a high-temperature setting process. The setting temperature depends on the type of yarn. After setting, the first yarn shrinks at a high temperature, thereby partially covering the second yarn that is gathered to the surface layer, so that the surface layer only presents the color effect of the first yarn, and the cloth surface is clean.

[0058] Among them, as a preferred embodiment of this embodiment, a circular weft knitting machine is used to weave the fabric.

[0059] As a preferred embodiment of this embodiment, the first yarn is spandex core-spun yarn, the second yarn is monofilament, and the third yarn includes spandex core-spun yarn and chemical fiber low-elastic yarn.

[0060] The weft knitted fabric of the present embodiment is a plain woven fabric with a raised flower pattern effect, which gives the fabric a three-dimensional flower pattern effect. The second yarn is woven with monofilament, and the raised flower pattern of the second fabric is full, and the shape and size of the flower pattern are not restricted, and the design range is wide. The first yarn is woven with elastic yarn, and after weaving, it undergoes a heat setting process, the yarn shrinks, and the surface layer of the fabric is tight and delicate. The surface layer only shows the color of the first yarn, and the second yarn is hidden therein, so that the color of the surface layer is cleaner.

[0061] Example 2

[0062] This embodiment is an extended embodiment of embodiment 1. The fabric further includes a third knitting area 3, the third knitting area 3 includes a third surface layer 31, a second middle layer 33 and a third bottom layer 32, and the height of the third knitting area 3 is greater than that of the second knitting area 2; the knitting yarn also includes the first yarn, wherein,

[0063] The first yarn connects the third surface layer 31 and the third bottom layer 32 in an up-and-down loop manner to form a second middle layer 33, all the third yarns form the third surface layer 31, the fourth yarn forms the third bottom layer 32, and the first yarn, the second yarn, the elastic yarn in the third yarn and the fourth yarn together form the first bottom layer 12.

[0064] As a preferred embodiment of the present invention, the first yarn is a monofilament and the second yarn is a multifilament. Due to the different rigidities of the monofilament and the multifilament, the monofilament has a greater rigidity and the pattern formed by it is more three-dimensional and fuller, while the height of the pattern formed by the multifilament is relatively low. Thus, a third weaving area 3 and a second weaving area 2 with different heights are formed, enriching the three-dimensional effect of the fabric.

[0065] As a preferred embodiment of this embodiment, the first yarn is a monofilament, and the second yarn includes alternatingly woven monofilaments and multifilaments. Similarly, due to the presence of the multifilaments in the second yarn, the overall height of the pattern of the second weaving area 2 formed thereby is lower than that of the third weaving area 3.

[0066] As a preferred embodiment of this embodiment, the first yarn includes monofilaments and multifilaments woven alternately, and the second yarn is multifilament.

[0067] As a preferred mode of this embodiment, the first yarn forms an upper and lower tuck loop structure with spaced needles or full needles in the second middle layer 33; when it is a spaced needle tuck loop structure, the pattern formed is softer, and when it is a full needle tuck loop structure, the pattern formed has good resilience and stiffness.

[0068] The knitting steps of the fabric of this embodiment also include: the fabric also includes a third knitting area 3, the knitting yarn thereof also includes the first yarn, and the knitting steps also include:

[0069] (5) Weaving the third weaving area 3: using the third yarn to weave to form the third surface layer 31; using the fourth yarn to weave to form the third bottom layer 32; using the first yarn to form the second middle layer 33 by tucking the third surface layer 31 and the third bottom layer 32;

[0070] (6) Weaving junction area: using the first yarn to weave adjacent tuck stitches and looping stitches on the first bottom layer 12 and fixing the tuck stitches of the elastic yarn in the third yarn to the bottom layer;

[0071] In the knitted fabric, the first bottom layer 12 is formed by the first yarn, the second yarn and the elastic yarn in the third yarn.

[0072] Example 3

[0073] This embodiment provides a partial knitting structure of a shoe upper, the knitting pattern of the shoe upper is as follows: Figure 4 As shown, the 5 routes are a minimum weaving unit, where:

[0074] The first route is to knit the fourth yarn on the lower plate with one alternate needle and knit on the fourth needle position of the upper plate;

[0075] The second route is that the fourth yarn is knitted on the lower disc one by one, and the second route's spacer needles are staggered with the first route's spacer needles. At the same time, the 10th and 18th needle positions of the lower disc are tucked, and the 5th needle position of the upper needle disc is knitted;

[0076] The third route is the knitting of the third yarn, which is an elastic yarn, which is knitted on the upper plate with dense needles and tucked on the lower plate at the same time, and the 11th to 17th needle positions are only knitted on the upper plate;

[0077] The 4th route is the 1st-10th needle positions and the 12th-17th needle positions of the first yarn lower bobbin are knitted with two-spaced and one-spaced needles, and the 11th-17th needle positions are knitted to connect the top layer and the bottom layer. The 4th route is monofilament;

[0078] The 5th route is for the second yarn to be tucked at the 4th / 5th / 7th / 9th needle positions of the lower disc and the 4th / 6th and 8th needle positions of the upper disc, the 10th / 18th needle positions of the lower disc are looped, and the 11th-17th needle positions of the lower disc are floating yarns; the 5th route is for multifilament;

[0079] The upper and lower tuck structures of the 4th route form a raised pattern in the third weaving area 3, the upper and lower tuck structures of the 5th route form a raised pattern in the second weaving area 2, and the corresponding loop structures of the 4th / 5th routes form the first weaving area 1, thereby forming a fabric with different layer heights.

[0080] By repeating the above knitting action, a multi-layer undulating high-low-layer and high-air-layer sandwich jacquard fabric can be obtained.

[0081] Example 4

[0082] This embodiment is a variation of the embodiment 3, and the main difference lies in the third route weaving. In this embodiment, the third route can also include two yarns, one of which is an elastic yarn and the other is a low-elastic yarn. The weaving action includes: the elastic yarn of the third yarn is weaved on the upper disc and tucked in the lower disc every other time, and it is a floating yarn at the 11th to 17th needle positions; the low-elastic yarn in the third yarn is only weaved on the dense needles of the upper disc; the rest of the weaving actions are the same as those in the embodiment 3. By repeating the above weaving actions, a multi-layer undulating high-low layer and high-air layer sandwich jacquard fabric can be woven.

[0083] The multi-layer undulating high-low-layer high-air-layer sandwich jacquard fabric of the above-mentioned embodiment can be used in the field of shoes and clothes, home textiles or bags, such as shoe uppers, clothing, curtains, bed sheets, quilt covers, and bags.
