Description

Invisible mesh fabric with anti-shedding and anti-curling properties Technical Field

[0001] The invention relates to a fabric, in particular to an invisible mesh fabric with soft hand feeling, large opening, high recovery rate and the functions of preventing falling apart and curling. Background Art

[0002] With the development of textile technology, designers have made great breakthroughs in the design of garments and the demand and use of fabrics. New products with fashionable appearance, different styles, functional fabrics, etc. are becoming more and more popular in garments.

[0003] At present, most garment fabrics on the market are relatively independent in terms of appearance, functionality, and practicality, and are not well integrated. This requires the addition of other fabrics or processes during garment processing to achieve the design effect, but this will inevitably increase the cost of garments and make some styles of garments unable to provide users with a good wearing experience.

[0004] To meet usage requirements, some existing fabrics have mesh holes, but these holes are exposed on the outside of the fabric, affecting its decorative properties in some situations. Furthermore, many existing fabrics are woven with elastic yarns for comfort, but these yarns have poor resistance to unraveling and are often woven from a single set of yarns, resulting in limited stretchability. Technical issues

[0005] The invention provides an invisible mesh fabric with anti-loosening and anti-curling properties, which has good recovery and anti-loosening properties and is not prone to curling problems. Technical Solutions

[0006] An invisible mesh fabric with anti-loosening and anti-curling properties, comprising a fabric body, wherein the fabric body is woven from at least four groups of yarns, including yarn Y1, yarn Y2, yarn Y3, and yarn Y4, which are interlaced and bound with each other. The fabric body is provided with a plurality of mesh holes, which can change in size freely when the fabric body is stretched by an external force. The bottom surface of the fabric body is a flat surface, wherein:

[0007] Yarn Y1 is an elastic yarn, which is fully threaded through the comb GB1 of the weaving equipment to form a warp flat structure during weaving; yarn Y2 is a non-elastic yarn, which is fully threaded through the comb B2 to form a braid chain structure during weaving; yarn Y3 is an non-elastic yarn, which is evenly divided into two sets of yarns during weaving, and half of them are respectively threaded through the comb GB3 and comb GB4 to form a variable weft inlay structure, and yarn Y3 and yarn Y2 together form a mesh whose size can change freely when the fabric body is stretched by external force; yarn Y4 is spandex, which is evenly divided into two sets of yarns during weaving, and half of them are respectively threaded through the comb GB5 and comb GB6 to form a weft inlay structure, and the two sets of yarns divided by yarn Y4 have opposite yarn padding directions, so that the bottom surface of the fabric body is flat, and yarns Y1 and Y2 form coils at each corresponding needle position on the weaving equipment, and yarns Y3 and Y4 pass through the coils formed by yarns Y1 and Y2 and are intertwined.

[0008] The two sets of yarns divided evenly from the yarn Y3 form a variable weft insertion structure with a course cycle number of ≥4 and no maximum number limit when half-threaded on the combing bars GB3 and GB4.

[0009] The yarn Y3 is evenly divided into two sets of yarns, which are threaded on the comb in the following ways: 1 threaded and 1 empty, and 1 empty and 1 threaded. The two sets of yarns are combined to form a full threading, and the two sets of yarns are in the same direction or in the opposite direction.

[0010] The two sets of yarns into which the yarn Y4 is evenly divided are threaded on the comb bar in the following ways: 1 threaded and 1 empty, and 1 empty and 1 threaded, and the two sets of yarns are combined to form a full thread.

[0011] The inlay structure of the yarn Y1 when weaving on the comb GB1 is 1-0 / 1-2 / / or 0-1 / 2-1 / / ; the inlay structure of the yarn Y2 when weaving on the comb GB2 is 1-0 / 0-1 / / or 0-1 / 1-0 / / ; the inlay structure of the yarn Y3 when weaving on the comb GB3 and the comb GB4 is 0-0 / 2-2 / / ; the inlay structure of one set of yarns divided from the yarn Y4 when weaving on the comb GB5 is 0-0 / 1-1 / / , and the structure of the other set of yarns divided from the yarn Y4 when weaving on the comb GB6 is 1-1 / 0-0 / / .

[0012] The yarn Y1 is core-spun yarn or spandex, and has a linear density between 20D and 70D, preferably 30D.

[0013] The yarn Y2 is made of nylon or polyester, and has a linear density between 20D and 90D, preferably 30D.

[0014] The yarn Y3 is nylon or polyester, and has a linear density between 20D and 140D, preferably 40D.

[0015] The yarn Y4 is spandex with a linear density between 70D and 560D.

[0016] The sizes of the plurality of meshes are the same or different. Beneficial effects

[0017] Compared with the prior art, the present invention has the following technical effects:

[0018] At each needle position, yarns Y3 and Y4 pass through the coils formed by Y1 and Y2, so that yarns Y3 and Y4 are intertwined with the coils. The excellent shrinkage of yarn Y1 is used to make the coil at this position retract to the maximum extent. Yarn Y1 at this coil position always remains in a retracted state, so that the mutual friction between each yarn and coil is enhanced, that is, the mutual binding ability between each yarn and coil is enhanced, thereby improving the tensile properties of the fabric and effectively preventing the fabric from unraveling after cutting and curling after pulling.

[0019] The mesh is formed by weaving together the inelastic yarns Y2 and Y3. Driven by the elastic yarns Y1 4 which always maintain their retractility, the mesh is driven to shrink when the fabric is not subjected to external pulling force. At this time, the entire fabric has almost no mesh visible from the outside. As the fabric is pulled, the mesh will gradually appear and its size will also change. The whole fabric adopts core-spun yarn, spandex, nylon and other yarns, which has the characteristics of soft hand feel. At the same time, through the weaving of the corresponding organizational structure and the mutual interlacing and restraint between the yarns, the opening is larger and the recovery rate is high. After cutting, it will not fall apart or curl, which is very suitable for underwear, sportswear and other clothing. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1

[0031] Referring to Figures 1-7, an invisible mesh fabric with anti-loosening and anti-curling features includes a fabric body, wherein the fabric body is woven from four groups of yarns, namely, yarn Y1, yarn Y2, yarn Y3, and yarn Y4, which are intertwined and bound with each other. Each group of yarns is connected to each other, forming a pulling force in both the warp and weft directions, thereby increasing the tensile force in the warp and weft directions. A plurality of mesh holes are provided on the fabric body, and the size of the mesh holes can change freely when the fabric body is stretched by external force. The bottom surface of the fabric body is a flat surface.

[0032] The yarn Y1 is an elastic yarn, which is fully threaded through the flat warp structure of the guide bar GB1 of the weaving equipment during weaving.

[0033] Yarn Y2 is a non-elastic yarn and is fully threaded through the guide bar B2 in a chain-knitting structure during knitting.

[0034] Yarn Y3 is a non-elastic yarn and is evenly divided into two sets of yarns, Y31 and Y32. During weaving, yarn Y31 is half-threaded on bar GB3 and yarn Y32 is half-threaded on bar GB4, creating a variable weft insertion structure with a course repetition number of ≥4, with no maximum limit. Yarn Y3 and yarn Y2 together form mesh holes that can change in size when the fabric is stretched by external forces. When the fabric is not subjected to external tension, the mesh holes are contracted by the retractile properties of yarn Y1, making them invisible or almost invisible from an external perspective. When the fabric is subjected to external tension, the mesh holes gradually become visible due to the stretching of the yarns. As the tension increases, the mesh holes gradually become larger. If multiple mesh holes of different sizes are required, yarn Y3 can be offset according to design requirements during weaving to form mesh holes of varying sizes.

[0035] Yarn Y4 is spandex and is evenly divided into two sets of yarns, Y41 and Y42. During weaving, yarn Y41 is half-threaded onto bar GB5, and yarn Y42 is half-threaded onto bar GB6, forming a weft inlay structure. The inlay directions of yarns Y41 and Y42 are opposite, making the bottom surface of the fabric smooth. Yarns Y1 and Y2 form loops at each corresponding needle position on the weaving equipment. Yarns Y3 and Y4 penetrate the loops formed by yarns Y1 and Y2 and interlace them. The excellent shrinkage of yarn Y1 maximizes the retraction of the loops at this position, enhancing the mutual friction between the yarns and loops. This strengthens the mutual restraint between the yarns and loops, thereby improving the fabric's tensile properties and effectively preventing unraveling and curling after cutting.

[0036] Example 2

[0037] Referring to Figures 2-7, the two sets of yarns into which the yarn Y3 is evenly divided are threaded on the comb in the manner of 1 threaded and 1 empty, and 1 empty and 1 threaded. The two sets of yarns are combined to form a full threading. The two sets of yarns are in-laid yarns in the same direction or in-laid yarns in the opposite direction, and the reverse yarn is preferred.

[0038] The two sets of yarns into which the yarn Y4 is evenly divided are threaded on the comb bar in the following ways: 1 threaded and 1 empty, and 1 empty and 1 threaded, and the two sets of yarns are combined to form a full thread.

[0039] The inlay structure of the yarn Y1 when woven on the combing bar GB1 is 1-0 / 1-2 / / , as shown in Figure 2, or 0-1 / 2-1 / / . The inlay structure of the yarn Y2 when woven on the combing bar GB2 is 1-0 / 0-1 / / , as shown in Figure 3, or 0-1 / 1-0 / / . The inlay structure of the yarn Y31 when woven on the combing bar GB3 and the yarn Y32 when woven on the combing bar GB4 are 0-0 / 2-2 / / and 2-2 / 0-0 / / , as shown in Figures 4 and 5. The inlay structure of the yarn Y41 when woven on the combing bar GB5 is 0-0 / 1-1 / / , and the structure of the yarn Y42 when woven on the combing bar GB6 is 1-1 / 0-0 / / , as shown in Figures 6 and 7.

[0040] Furthermore, the yarn Y1 is core-spun yarn or spandex, with a linear density between 20D and 70D, preferably 30D. The yarn Y2 is nylon or polyester, with a linear density between 20D and 90D, preferably 30D. The yarn Y3 is nylon or polyester, with a linear density between 20D and 140D, preferably 40D. The yarn Y4 is spandex, with a linear density between 70D and 560D.

[0041] Regarding the elasticity of yarn Y1 and yarn Y4, generally, the elasticity of yarn Y1 is selected to be greater than the elasticity of yarn Y4.

[0042] At each needle position during knitting, yarns Y3 and Y4 will pass through the loops formed by Y1 and Y2. Due to the excellent shrinkage of Y1, the loop at this position will retract to the maximum extent, and the mutual friction between the yarns and the loops will be enhanced, that is, the mutual binding ability between the yarns and the loops will be enhanced, thereby improving the tensile properties of the fabric and effectively preventing the fabric from unraveling after cutting and curling after pulling.

[0043] The following is an explanation using a production example.

[0044] 1. Yarn warping:

[0045] 1) Warping of filament yarn:

[0046] Warping machine model: Karl Mayer DS 21 / 30 NC-2, negative yarn feeding.

[0047] Warping temperature: 23℃ Warping humidity: 65%

[0048] 2) Warping of spandex:

[0049] Warping machine model: Karl Mayer DSE-H21 / 30 NC-2, positive yarn feeding.

[0050] Warping temperature: 24℃ Warping humidity: 78%

[0051] 2. Weaving: Machine model is FJ65 / 1-B, gauge is E28

[0052] According to the expected development goals, various parameters such as machine pulling, yarn feed amount, etc. are reasonably adjusted to ensure smooth startup.

[0053] 3. Yarn selection and threading:

[0054] Y1: PU 30D full wear;

[0055] Y2: PA6 20D / 34F SD FDY full penetration;

[0056] Y3: PA6 30D / 68F SD FDY 1 through 1 empty;

[0057] Y4: PA6 30D / 68F SD FDY 1 empty and 1 worn;

[0058] Y5: PU 70D 1 through 1 empty;

[0059] Y6: PU 70D 1 empty and 1 worn.

[0060] 4. Production process:

[0061] Rough open width washing → 195℃ pre-dyeing → overflow dyeing → 160℃ finishing

[0062] 5. Finished product tensile test:

[0063] Test standard: LTD03 7.5lbf

[0064] Specific conditions: stretching speed is 10 inches / minute, return speed is 20 inches / minute

[0065] The clamp width is 3 inches and the clamp distance is 5 inches.

[0066] Test results: Opening --- L: 183%, W: 195%

[0067] Response rate: immediate: 93%, 5 minutes: 97%

[0068] illustrate:

[0069] 1) Recovery rate = (length after stretching - length after recovery) / (length after stretching - original length) x 100

[0070] 2) Instant recovery rate: the recovery rate is calculated by measuring and calculating the test sample immediately after the tensile performance test is completed.

[0071] 3) 5-minute recovery rate: After the tensile performance test is completed, the test sample is immediately removed and laid flat for 5 minutes to measure and calculate the recovery rate.

[0072] It can be seen from the above actual tests that the fabric obtained according to the present application has high recovery and large openness.

[0073] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
