[0038] The present invention will be further described below through examples and drawings.

[0039] Example 1

[0040] An air layer openwork knitted jacquard fabric, such as Figure 1 As shown, it includes a surface layer, a bottom layer and an intermediate layer for connecting the surface layer and the bottom layer, which are integrally woven by a circular weft knitting machine. The woven yarn of the surface layer includes a first yarn 2, the woven yarn of the bottom layer includes a second yarn 1, and the woven yarn of the intermediate layer includes a third yarn 3.

[0042] The full through hole includes at least five weaving rows, and the weaving steps include:

[0043] (1) First knitting row: The third yarn is knitted in sequence with two rows of connecting tissues connected to the top layer and the bottom layer, and the first yarn is knitted for the top layer, wherein the 4 / 4 knitting row is knitted for the top layer with the bottom layer tucking loops; the second yarn is knitted for the bottom layer with full stitches; then the top layer needles of the 4 / 4 knitting row and the 5 / 5 knitting row are transferred to the bottom layer;

[0044] (2) Second weaving row: The third yarn is used to weave two rows of connecting tissues connecting the surface layer and the bottom layer in sequence, the first yarn is used for surface weaving, and the fourth weaving row is used for surface layer floating thread weaving; the fifth weaving row is used for surface layer tucking weaving, and the second yarn is used for full stitch bottom weaving;

[0048] The first to fifth knitting lines are the minimum knitting loops for knitting a fully open hole;

[0049] The fully transparent hole structure can then continue to be woven as described above to form continuous transparent holes, or other tissue structures can be woven to form point-shaped fully transparent holes at positions corresponding to the 4th / 5th weaving rows.

[0050] The weaving rows and columns in this embodiment are only exemplary, wherein the weaving columns of the tuck stitch used for weaving the through-hole structure are not limited to the 4th and 5th weaving columns, but may also be the 2nd, 3rd or other weaving columns, and the required weaving column positions may be set as needed. It should be noted that in one weaving row, the weaving columns of the tuck stitch used for weaving the full through-hole 4 structure are not limited to one group, and may be determined according to the required number of full through holes 4. For example, when 10 full through holes 4 are required in one weaving row, the number of the tuck stitches is 10, and they are distributed in the required weaving columns.

[0051] At the same time, it should be noted that M can represent not only one row of weaving columns, but also two rows of weaving columns. The above embodiment shows two rows of weaving columns. In this structure, it is easier to turn the needle. Of course, one row of weaving columns can also complete the structure, which can be set as needed.

[0052] Example 2

[0053] An air layer perforated knitted jacquard fabric comprises a surface layer, a bottom layer and an intermediate layer for connecting the surface layer and the bottom layer, the knitting yarn of the surface layer comprises a first yarn 2, the knitting yarn of the bottom layer comprises a second yarn 1, the knitting yarn of the intermediate layer comprises a third yarn 3, a plurality of semi-permeable holes are arranged on the surface layer, and the knitting yarn at the semi-permeable holes comprises a second knitting yarn and a third knitting yarn. The semi-permeable holes are in the shape of dots. The first yarn 2 is a 200D / 72F black semi-dull polyester composite yarn, the second yarn 1 is a 200D / 48F white semi-dull polyester composite yarn, and the third yarn 3 is a 50D transparent monofilament.

In the fabric structure, it not only has the air permeability effect brought by the through-holes, but also has the two-color dot jacquard effect.

[0054] like Figure 3 As shown, a knitting process of semi-permeable holes formed by turning needles is exemplified, and the knitting steps include:

[0055] 10) First knitting row: the third yarn is knitted to connect the top layer and the bottom layer; the first yarn is knitted with full needles on the top layer; the second yarn is knitted with full needles on the bottom layer; the knitting needles in the 5th knitting row of the top layer are transferred to the bottom layer;

[0058] The first to third weaving rows are the minimum weaving cycles for weaving semi-permeable holes. The next weaving rows can cycle the weaving structure of the semi-permeable holes to form continuous semi-permeable holes, or can be woven in other structures, and the weaving needle positions corresponding to the fifth weaving row form dot-shaped semi-permeable holes.

[0059] The weaving rows and columns in this embodiment are only exemplary, wherein the weaving column where the turning needles for weaving a through-hole structure are located is not limited to the 4th weaving column, it can also be the 2nd or 3rd or other weaving columns, and the required weaving column position can be set as needed. At the same time, it should be noted that in a weaving row, the weaving column of the turning needles for weaving a through-hole structure is not limited to one group, it can be determined according to the required number of semi-permeable holes. For example, when 10 such semi-permeable holes are needed in a weaving row, the number of the turning needles can be set to 10, and distributed in the required weaving columns.

[0060] At the same time, the needle transfer and tuck weaving sequences in this embodiment are only exemplary, and the tuck weaving for the holes is not limited to twice, it can also be one tuck or three tucks. We should understand that different numbers of tucks are expressed on the fabric surface as semi-permeable holes of different sizes, which can be set to the required position as needed.

[0061] In this embodiment, the second yarn 1 of the bottom layer can also include two or more different colors, and be different from the color of the first yarn 2. When semi-permeable holes are formed at corresponding positions of the different color yarns of the second yarn 1, a multi-color dot jacquard effect can be formed at the same time under the structure of the semi-permeable holes.

[0064] The knitting method of the knitted fabric is the same as that of Example 2, the only difference being that step 3) is a stitch-turning structure in which a plurality of continuous knitting rows are turned from the surface layer to the 4th knitting row of the bottom layer. The more continuous knitting structures are, the longer the length of the semi-permeable holes formed is.

[0065] Of course, the fourth weaving row is turned over only for the position of the semi-permeable hole 5 in this embodiment, and the corresponding weaving row and layout quantity can be set according to the required position of the semi-permeable hole.

[0066] The semi-permeable holes 5 of the fabric formed in this embodiment are white, and the rest of the surface layer is black. In this fabric structure, it not only has the ventilation effect brought by the semi-permeable holes 5, but also has a two-color strip jacquard effect. In this embodiment, the second yarn 1 of the bottom layer can also include two or more different colors, which are different from the color of the first yarn 2. When the semi-permeable holes are formed at the corresponding positions of the different color yarns of the second yarn 1, it can form a multi-color strip jacquard effect under the structure of the semi-permeable holes 5.

The bottom layer is woven with cellulose fiber yarn, which is more skin-friendly. The bamboo fiber yarn can also be bamboo fiber / polyester blended yarn, bamboo fiber / cotton blended yarn, graphene nylon / cotton blended yarn, etc., to obtain better physical properties or health care properties.
