Description

Technical Field

[0001] This invention belongs to the field of textile fabric technology, specifically relating to a method for preparing warp-knitted double-sided fleece fabric with moisture-wicking and quick-drying functions. Background Technology

[0002] With the continuous improvement of people's living standards and the continuous development of textile technology, people's requirements for the functionality of fabrics are also getting higher and higher. For fabrics used for a long time in high-temperature environments, excellent moisture-wicking and quick-drying properties are generally required. Existing fabrics have poor moisture-wicking and quick-drying functions or the function is not long-lasting. During use, moisture cannot be quickly discharged, which can easily make people feel stuffy.

[0003] Patent application number 201220566610.4 discloses a breathable full-grain ultra-sensitive simulated leather, which is formed by bonding a surface layer of warp-knitted microfiber napped fabric and a bottom layer of two layers of knitted brushed fabric with resin. The resulting fabric has good breathability, but the use of resin between the surface and bottom layers makes the fabric's moisture absorption and wicking performance poor and it is not environmentally friendly. Patent application number 202010561728.7 discloses a method for preparing a moisture-wicking, quick-drying, antibacterial, down-proof, and easy-to-clean fabric. It selects all-cotton, all-polyester, cotton-polyester blend, polyester-spandex blend, or polyester-cotton-spandex blend fabrics, and uses a working liquid containing moisture-wicking, quick-drying, antibacterial, down-proof, and penetrating agents to treat the fabric, giving it good moisture-wicking, quick-drying, antibacterial, down-proof, and easy-to-clean functions. However, the use of moisture-wicking, quick-drying, antibacterial, and down-proof finishing agents makes the fabric's functionality not lasting. Summary of the Invention

[0004] The present invention aims to solve the problems of poor moisture absorption and quick-drying properties and short durability of existing fabrics, and provides a warp-knitted double-sided fleece fabric with moisture absorption and quick-drying function and its preparation method.

[0005] A warp-knitted double-sided fleece fabric with moisture-wicking and quick-drying functions is disclosed. The fabric is woven on a warp knitting machine using three guide bars. One side of the fabric has an extension yarn structure, and the other side has a loop structure. Both sides of the fabric are brushed. The fabric consists of a first extension yarn layer, a second extension layer, a third extension layer, a first loop layer, a second loop layer, and a third loop layer from top to bottom. The loops in the first loop layer, the second loop layer, and the third loop layer overlap to create a fabric effect that is partially concave and partially convex.

[0006] Furthermore, the first coil layer has more coils than the second coil layer, and the second coil layer has more coils than the third coil layer.

[0007] Furthermore, the first extension layer and the first coil layer are woven from moisture-wicking fiber yarn with an irregular cross-section having micropores or grooves on the surface.

[0008] Furthermore, the second extension layer and the second coil layer are woven using moisture-wicking fiber yarns.

[0009] Furthermore, the third extension layer and the third coil layer are woven using moisture-wicking and quick-drying fiber yarns.

[0010] A method for weaving a warp-knitted double-sided fleece fabric with moisture-wicking and quick-drying properties, comprising the following steps:

[0011] (1) The three guide bars of the warp knitting machine are used for weaving, including GB1, GB2 and GB3;

[0012] (2) The yarn padding number of the first comb GB1 is: 0-1 / 2-1 / 3-2 / 1-2 / / , and the yarn threading method is one thread and one loop, which are woven to form the first extension yarn layer and the first loop layer of the fabric;

[0013] (3) The yarn padding number of the second comb GB2 is: 3-2 / 1-2 / 0-1 / 2-1 / / , and the yarn threading method is one thread and one empty, which is woven to form the second extension yarn layer and the second loop layer;

[0014] (4) The padding yarn number of the third comb GB3 is: 1-2 / 1-0 / / , the yarn threading method is full threading, and the yarn is woven to form the third extension yarn layer and the third loop layer;

[0015] (5) The front and back sides of the fabric are brushed, and then washed, dried and calendered in sequence to obtain a warp-knitted double-sided fleece fabric with moisture-absorbing and quick-drying function.

[0016] The advantages of this invention are as follows:

[0017] (1) The fabric has excellent moisture absorption and quick-drying properties: the first extension layer can quickly absorb moisture and sweat from the surface of human skin. Some of the absorbed moisture and sweat will quickly diffuse to the second and third extension layers and then evaporate, while some will diffuse to the first coil layer and then be absorbed and evaporated by the second and third coil layers in sequence. The fine pile structure formed on the front side of the fabric can improve the overall comfort of the fabric. The concave and convex structure and pile structure of the coil on the reverse side of the fabric can make the conducted moisture and sweat evaporate quickly, and the fabric conduction function lasts.

[0018] (2) The fabric weaving method is simple and easy to implement, no other functional additives are required, the preparation process is green and environmentally friendly, and the fabric is suitable for sofa covering fabrics and has good application prospects. Attached Figure Description

Detailed Implementation

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Example 1

[0025] A warp-knitted double-sided fleece fabric with moisture-wicking and quick-drying properties, such as Figure 1 , Figure 2 As shown, the warp-knitted double-sided pile fabric comprises a six-layer structure, from top to bottom: a first extension yarn layer 1, a second extension yarn layer 2, a third extension yarn layer 3, a first loop layer 4, a second loop layer 5, and a third loop layer 6. The first extension yarn layer 1 includes a first pile layer 11 and a first extension yarn base layer 12, and the third loop layer 6 includes a third loop base layer 61 and a second pile layer 62. The fabric is prepared using a warp knitting machine with three guide bars, resulting in a fabric with a tight extension yarn structure on one side and a tight concave-convex loop structure on the other. Both sides are then brushed to form the pile layer.

[0026] The preparation method includes the following steps:

[0027] (1) Among the three combs for weaving warp-knitted fabric, the first comb GB3 uses shaped cross-section moisture-wicking fiber yarns with micropores or grooves on the fiber surface to fully weave and form the first extension layer and the first loop layer of warp-knitted double-sided fleece fabric. The padding yarn numbers of the first comb GB1 are: 0-1 / 2-1 / 3-2 / 1-2 / / , and the yarn threading method is one thread and one empty.

[0028] (2) The second extension layer 2 and the second loop layer 5 of the warp-knitted double-sided pile fabric are formed by non-full-through weaving of moisture-wicking fiber yarn on the second comb GB2. The padding yarn number of the second comb GB2 is: 3-2 / 1-2 / 0-1 / 2-1 / / , and the yarn threading method is one thread and one empty.

[0029] (3) The third comb GB1 is made of moisture-wicking and quick-drying fiber yarns to form the third extension layer 3 and the third loop layer 6 of warp-knitted double-sided fleece fabric. The padding yarn number of the third comb GB3 is: 1-2 / 1-0 / / , and the yarn threading method is full threading.

[0030] (4) The front and back sides of the fabric are brushed, and then washed, dried and calendered in sequence to obtain a warp-knitted double-sided fleece fabric with moisture-absorbing and quick-drying function.

[0031] The fabric's layered structure diagram and visualization of the reverse side's unevenness are shown below. Figure 3 As shown, the coils constituting the first coil layer 4, the second coil layer 5, and the third coil layer 6 are superimposed on each other, so that some areas form a single-layer coil structure (I) and some areas form a three-layer coil structure (III). The single-layer coil structure (I) has a concave effect, and the three-layer coil structure (III) has a convex effect.

[0032] The first coil layer 4 of the fabric has more coils than the second coil layer 5 and the third coil layer 6. The front side of the fabric exhibits a dense, fine pile structure due to the first pile layer 11 of the first extension layer 1. The reverse side exhibits a uniform uneven and pile structure due to the different numbers of coils in the first coil layer 4, the second coil layer 5, the third coil layer 6, and the second pile layer 62 on the third coil layer 6. This results in excellent moisture-wicking and quick-drying properties. The first extension layer 1 of the warp-knitted double-sided pile fabric, due to the use of irregularly shaped cross-section moisture-wicking fiber yarns with micropores or grooves on the fiber surface and the design of the dense pile and extension layer structure,... It can quickly absorb moisture and sweat from the surface of human skin. Some of the absorbed moisture and sweat quickly diffuses and is released to the yarns that make up the second extension layer 2, and is then absorbed and evaporated by the yarns that make up the third extension layer 3. Some of the moisture and sweat diffuses through the second extension layer 2 and the third extension layer 3 to the first coil layer 4, and is then absorbed and evaporated by the second coil layer 5 and the third coil layer 6 in sequence. Therefore, the designed warp-knitted double-sided pile fabric has excellent moisture absorption and quick-drying performance. The fine pile structure on the front of the fabric can improve the overall comfort of the fabric, and the concave and convex structure and pile structure on the reverse side of the fabric can make the moisture and sweat transmitted there evaporate quickly.

[0033] In addition, the combination of irregularly shaped cross-section moisture-wicking fiber yarns, moisture-wicking fiber yarns, and moisture-wicking quick-drying fiber yarns gives the fabric a good and long-lasting moisture-wicking and quick-drying effect without the use of functional additives. Example 2

[0034] A method for preparing a warp-knitted double-sided fleece fabric with moisture-wicking and quick-drying functions involves first preparing a warp-knitted greige fabric on a warp-knitting machine using three guide bars. This results in a fabric with one side having a tightly stretched yarn structure and the other side having a tightly convex-concave loop structure. Then, both sides of the prepared warp-knitted greige fabric are napped. Finally, the napped fabric undergoes finishing processes including washing, drying, and calendering. Figure 1 , Figure 2 As shown, the warp-knitted double-sided fleece fabric comprises a six-layer structure, and its overall structure, the fiber yarns used, and the principle of producing the moisture-wicking and quick-drying effect are the same as in Example 1.

[0035] The preparation method includes the following steps:

[0036] (1) Among the three combs, the yarn padding number of the first comb GB1 is: 1-0 / 2-3 / / , and the yarn threading method is one thread and two empty;

[0037] (2) The yarn padding number of the second comb GB2 is: 2-3 / 1-0 / / , and the yarn threading method is one thread and two empty;

[0038] (3) The yarn padding number of the third comb GB3 is: 1-2 / 1-0 / / , and the yarn threading method is full threading;

[0039] (4) The front and back sides of the fabric are brushed, and then washed, dried and calendered in sequence to obtain a warp-knitted double-sided fleece fabric with moisture-absorbing and quick-drying function.

[0040] The fabric's layered structure diagram and visualization of the reverse side's unevenness are shown below. Figure 4 As shown, the coils constituting the first coil layer 4, the second coil layer 5, and the third coil layer 6 are superimposed on each other, so that some areas form a single-layer coil structure (I), some areas form a two-layer coil structure (II), and some areas form a three-layer coil structure (III). The single-layer coil structure (I) forms a concave effect, the two-layer coil structure (II) forms a small convex effect, and the three-layer coil structure (III) forms a large convex effect.
