Description

Technical Field

[0001] This utility model relates to the field of textile product technology, and in particular to a warp-knitted cotton fleece fabric. Background Technology

[0002] Weft-knitted cotton fleece, due to its soft feel and diverse styles, has become a popular knitted fabric in recent years, favored by a wide range of apparel companies, home textile companies, and traders both domestically and internationally.

[0003] The fabric structure of weft-knitted cotton fleece is relatively simple, typically consisting of a base fabric layer, a connecting pile layer, a binding layer, and a pile layer. The base fabric layer, as the first layer, is a fully looped structure, also known as the loop layer. The connecting pile layer consists of two horizontal loops with two floats arranged sequentially, with adjacent rows alternating. The binding layer, as the third layer, also consists of two horizontal loops with two floats arranged sequentially, with adjacent rows alternating, corresponding one-to-one with the second layer. The pile layer, as the fourth layer, is formed by the floats of the connecting pile layer passing through the binding layer and being cut during the knitting process. The binding layer laminates the connecting pile layer, fixing the pile in the pile layer. However, because the binding layer alone has a weak binding effect on the pile, and the weft knitting structure is relatively loose, the pile can easily be pulled out and fall off from the binding layer, resulting in shedding and affecting product quality. Utility Model Content

[0004] The purpose of this application is to provide a warp-knitted cotton fleece fabric to solve the problem that in the prior art, the binding effect of the weft-knitted cotton fleece on the fleece is weak due to the binding layer alone, and the weft knitting structure is relatively loose, which makes the fleece easily pulled out and fall off from the binding layer, resulting in shedding and affecting product quality.

The second chain layer is connected to the pile layer.

[0008] In a warp-knitted cotton fleece fabric described in this application embodiment, two coils in two adjacent rows of the first coil layer in the same column form a coil group, and several coil groups in the adjacent columns are staggered along the longitudinal direction.

[0014] The linear density of the third yarn and the fourth yarn are both 50D to 100D, and the number of single filaments is both 24F to 48F.

[0015] In the warp-knitted cotton fleece fabric described in this application embodiment, the second coil layer has a fully threaded coil structure.

[0016] In the warp-knitted cotton fleece fabric described in the embodiments of this application, the weft layer is a full-weft-insertion structure.

This solves the technical problem in the prior art that the binding effect of the binding layer on the fleece in weft-knitted fleece is weak, and the weft knitting structure is relatively loose, making it easy for the fleece to be pulled out and fall off from the binding layer, resulting in shedding and affecting product quality.

[0030] Because the binding effect of the binding layer on weft-knitted cotton fleece is relatively weak, and the weft knitting structure is relatively loose, the fleece is easily pulled out and falls off from the binding layer, resulting in shedding and affecting product quality.

[0031] In view of this, this application provides a warp-knitted fleece fabric. The concept involves setting up a first loop layer, a second loop layer, a weft layer, a first knitted chain layer, a second knitted chain layer, and a fleece layer. All of these layers are warp-knitted structures. The first loop layer passes through the second loop layer, the weft layer, and the first knitted chain layer before connecting to the second knitted chain layer. The second knitted chain layer connects to the fleece layer, creating a laminate between the second loop layer, the weft layer, the first knitted chain layer, and the second knitted chain layer and the first loop layer. This enhances the stability of the fleece layer and reduces shedding in the fleece fabric. This solves the technical problem in the prior art where the binding effect of the weft-knitted fleece layer on the fleece is weak, and the weft knitting structure is relatively loose, making it easy for the fleece to be pulled out and fall off, resulting in shedding and affecting product quality.

The base fabric 10 includes a first loop layer 11, a second loop layer 12, a weft insert layer 13, a first chain layer 14, and a second chain layer 15.

The first loop layer 11 passes through the second loop layer 12, the weft insert layer 13, and the first chain layer 14 and then connects to the second chain layer 15. The second chain layer 15 is connected to the fleece layer 20.

[0038] The second coil layer 12 is a fully threaded coil structure, the weft-inserting layer 13 is a fully threaded weft-inserting structure, and the first braided chain layer 14 is a fully threaded braided chain structure.

[0039] Specifically, in the first coil layer 11, two coils in two adjacent rows of the same column form a coil group 111. Several coil groups 111 in adjacent columns are staggered longitudinally. The coil area of ​​the first coil layer 11 occupies 50% of the area of ​​the base fabric 10. In the second chain layer 15, several chains in the same column are spaced apart. In the second chain layer 15, several chains in the same row are spaced apart. Each chain is positioned directly above a coil group 111 in the fabric thickness direction. The chain area of ​​the second chain layer 15 occupies 50% of the area of ​​the base fabric 10. In the plush layer 20, two plush fibers in two adjacent rows of the same column form a plush group 21. Several plush groups 21 are positioned directly above a chain in the fabric thickness direction. The plush area of ​​the plush layer 20 occupies 50% of the area of ​​the base fabric 10. The odd-numbered columns of the first coil layer 11... The coils, the odd-numbered rows of the second braided chain layer 15, and the odd-numbered rows of the plush layer 20 are woven from a set of first yarns 30. The even-numbered rows of coils in the first coil layer 11, the even-numbered rows of the second braided chain layer 15, and the even-numbered rows of the plush layer 20 are woven from a set of second yarns 40. The second coil layer 12 and the first braided chain layer 14 are woven from third yarns 50. The weft layer 13 is woven from fourth yarns 60. The first yarns 30 and the second yarns 40 are both semi-dull round-hole polyester DTY. The third yarns 50 and the fourth yarns 60 are both semi-dull polyester FDY. The linear density of the first yarns 30 and the second yarns 40 is 100D to 300D, and the number of filaments is 144F to 576F. The linear density of the third yarns 50 and the fourth yarns 60 is 50D to 100D, and the number of filaments is 24F to 48F.

[0040] In the first coil layer 11, two coils in two adjacent rows of the same column constitute a coil group 111. Several coil groups 111 in adjacent columns are staggered longitudinally to create a dot matrix distribution. For example, if the coil groups 111 in the first row are located in columns 2 / 4 / 6 / 8 / 10 / 12, the coil groups 111 in the second row are located in columns 1 / 3 / 5 / 7 / 9 / 11, the coil groups 111 in the third row are located in columns 2 / 4 / 6 / 8 / 10 / 12, and the coil groups 111 in the fourth row are located in columns 1 / 3 / 5 / 7 / 9 / 11. Columns 5 / 7 / 9 / 11, and so on; the second braided layer 15 has several braids in the same column spaced apart, and several braids in the same row spaced apart. Each of these braids is positioned directly above one of the several loop groups 111 in the fabric thickness direction, so that the braids of the second braided layer 15 are arranged in a dot matrix pattern. For example, if the braids in the first row are located in columns 2 / 4 / 6 / 8 / 10 / 12, then the braids in the second row are located in columns 1 / 3 / 5 / 7 / 9 / 11, and the braids in the third row are located in columns 2 / 4 / 6 / 8 / 10. / 12 columns, the braided chains in the fourth row are located in columns 1 / 3 / 5 / 7 / 9 / 11, and so on. The spacing between two adjacent braided chains in the same column is equal to the spacing between two adjacent coil groups 111 in the same column, and the spacing between two adjacent braided chains in the same row is equal to the spacing between two adjacent coil groups 111 in the same row. Two piles in two adjacent rows of the same column of the plush layer 20 form a pile group 21. Several pile groups 21 are located directly above several braided chains in the thickness direction of the fabric, so that the pile groups 21 of the plush layer 20 are arranged in a dot matrix. For example, if the plush group 21 in the first row is located in columns 2 / 4 / 6 / 8 / 10 / 12, then the plush group 21 in the second row is located in columns 1 / 3 / 5 / 7 / 9 / 11, the plush group 21 in the third row is located in columns 2 / 4 / 6 / 8 / 10 / 12, the plush group 21 in the fourth row is located in columns 1 / 3 / 5 / 7 / 9 / 11, and so on. The spacing between two adjacent plush groups 21 in the same column is equal to the spacing between two adjacent braids in the same column, and the spacing between two adjacent plush groups 21 in the same row is equal to the spacing between two adjacent braids in the same row.

[0041] Specifically, the cotton fleece fabric is woven by a six-bar double-needle bed warp knitting machine of type E22-E24. The six bars are GB1, GB2, GB3, GB4, GB5, and GB6. The first yarn 30, the second yarn 40, the third yarn 50, and the fourth yarn 60 are warped by six sets of warp heads. The third yarn 50 and the fourth yarn 60 are each divided into two groups. The first set of warp heads warps the first yarn 30, acting on GB3, for weaving odd-numbered rows of loops in the first loop layer 11, odd-numbered rows of chain stitches in the second chain stitch layer 15, and odd-numbered rows of pile in the pile layer 20 on the front and rear needle beds of the double-needle bed warp knitting machine. The second set of warp heads warps the second yarn 40, acting on GB4, for weaving even-numbered rows of loops in the first loop layer 11, even-numbered rows of chain stitches in the second chain stitch layer 15, and even-numbered rows of pile in the second chain stitch layer 15 on the front and rear needle beds of the double-needle bed warp knitting machine. The even-numbered rows of pile in the chain knitting and the pile layer 20, the third and fourth warp heads respectively warp the two sets of the fourth yarns 60, the fourth yarns 60 of the third warp head act on GB1, for knitting the weft layer 13 on the front needle bed of the double needle bed warp knitting machine, the fourth yarns 60 of the fourth warp head act on GB6, for knitting the weft layer 13 on the rear needle bed of the double needle bed warp knitting machine, the fifth and sixth warp heads respectively warp the two sets of the third yarns 50, the third yarns 50 of the fifth warp head act on GB2, for knitting the second loop layer 12 and the first chain knitting layer 14 on the front needle bed of the double needle bed warp knitting machine, the third yarns 50 of the sixth warp head act on GB4, for knitting the second loop layer 12 and the first chain knitting layer 14 on the rear needle bed of the double needle bed warp knitting machine.

[0042] In this structure, the odd-numbered rows of coils in the first coil layer 11, the odd-numbered rows of braided chains in the second chain layer 15, and the odd-numbered rows of pile in the pile layer 20 are woven from a set of first yarns 30. The even-numbered rows of coils in the first coil layer 11, the even-numbered rows of braided chains in the second chain layer 15, and the even-numbered rows of pile in the pile layer 20 are woven from a set of second yarns 40. That is, the first coil layer 11 passes through the second coil layer 12, the weft layer 13, and the first chain layer 14 and is connected to the second chain layer 15. The second chain layer 15 is connected to the pile layer 20, so that the first coil layer 11, the second chain layer 15, and the pile layer 20 on the front and rear needle beds are all integral structures. The pile of the pile layer 20 is formed by splitting the connecting yarn of the first yarn 30 and the second yarn 40 in the opening section between the front and rear needle beds of the double needle bed warp knitting machine.

[0043] Preferably, in order to tighten the first coil layer 11 and the second braided layer 15 to further enhance the stability of the plush layer 20, the theoretical warp feed amount of GB3 and GB4 is defined as R, and the actual warp feed amount of GB3 and GB4 is defined as r. Then r satisfies 0.8R < r < 0.95R, where cpc is the fabric longitudinal density, d is the needle tip thickness, and H is the spacing distance between the front and rear needle beds of the double needle bed warp knitting machine.

[0044] In summary, the warp-knitted cotton fleece fabric provided in this application embodiment comprises a first loop layer, a second loop layer, a weft insert layer, a first chain layer, a second chain layer, and a fleece layer. All of these layers are warp-knitted, with the first loop layer passing through the second loop layer, the weft insert layer, and the first chain layer before connecting to the second chain layer. The second chain layer is connected to the fleece layer, thus shaping the first loop layer. The process involves lamination to enhance the stability of the pile layer. By setting the actual warp feed of the first and second yarns to 0.8 to 0.95 times the theoretical warp feed, the first loop layer and the second chain layer are tightened, further enhancing the stability of the pile layer and reducing the shedding of the cotton fleece fabric. This solves the technical problem in the existing technology where the binding effect of the weft-knitted cotton fleece on the pile is weak due to the binding layer alone, and the weft knitting structure is relatively loose, making it easy for the pile to be pulled out and fall off from the binding layer, resulting in shedding and affecting product quality.
