Description

Technical Field

[0001] This invention relates to the field of clothing fabrics, specifically to a moisture-wicking and quick-drying fabric and its preparation method. Background Technology

[0002] As people's living standards improve, environmental pollution becomes increasingly serious. More and more modern people are pursuing a healthy and environmentally friendly lifestyle. In daily activities, people inevitably sweat to some extent. If sweat cannot be wicked away in time, it can make people feel stuffy and uncomfortable, affecting their quality of life and mood. This necessitates that clothing fabrics be comfortable, environmentally friendly, and have excellent moisture-wicking properties. Common moisture-wicking fabrics include polyester-cotton blends and pure cotton fabrics. Polyester fibers in polyester-cotton blends are hydrophobic fibers, which have a strong affinity for oil stains, easily absorbing them and are not easily degraded, affecting the wearing experience and being environmentally unfriendly. Pure cotton fabric is almost non-irritating to the skin, feels soft and not stiff, and is beneficial and harmless to the human body. It has good hygiene properties and is easily degradable. Moisture-wicking effects can be achieved by changing the weave structure or post-treatment, but the former has little effect, and the latter causes serious environmental pollution. Therefore, there is an urgent need for a soft, comfortable, safe, environmentally friendly, and quick-drying moisture-wicking fabric. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides a moisture-wicking and quick-drying fabric and its preparation method.

[0004] One embodiment of this application provides a method for preparing a moisture-wicking and quick-drying fabric, comprising the following steps: Step S1: Selection of cotton fibers and water-soluble fibers; Step S2: Spinning core-spun yarn, wherein cotton fiber is the outer yarn and water-soluble fiber is the inner yarn; Step S3: Remove the fibers to obtain pure cotton hollow yarn; Step S4: Dehydrate, dry, and wind the pure cotton hollow yarn; Step S5: The pure cotton hollow yarns after winding are combined and twisted together to obtain moisture-wicking and quick-drying yarn. Step S6: The obtained moisture-wicking and quick-drying yarn is retwisted to obtain retwisted yarn; Step S7: The fabric is woven using a fabric weaving process, wherein a low-count, weak-twist retwisted yarn is used as the front yarn and a high-count, strong-twist retwisted yarn is used as the back yarn, to weave a double-sided knitted fabric with a guide groove, wherein the front side is the skin-contact side.

[0005] Furthermore, in step S7, the low-count, weak-twist retwisted yarn has a count of 40-50S and a twist of 500T / M-800T / M; the high-count, strong-twist retwisted yarn has a count of 50-60S and a twist of 1200 T / M-1500 T / M.

[0006] Furthermore, in step S7, the fabric obtained by the fabric weaving process has a weight of 150-200 g / m². 2 .

[0007] Another embodiment of this application also provides a moisture-wicking and quick-drying fabric, which is prepared by the above-described preparation method.

[0008] This application provides a method for preparing a moisture-wicking and quick-drying fabric. The method employs a fabric weaving process, using low-count, low-twist retwisted yarn as the front yarn and high-count, high-twist retwisted yarn as the back yarn, to weave a honeycomb-shaped, textured double-sided knitted fabric with drainage channels. Specifically, a de-spun yarn process is used to remove the inner core yarn from the core-spun yarn, resulting in hollow pure cotton yarn. Besides the drainage channels' function in guiding sweat, the hollow structure of the pure cotton yarn also facilitates sweat wicking, further enhancing its perspiration-wicking function. Furthermore, the use of cotton fibers ensures the fabric's softness, comfort, and moisture-wicking properties. Attached Figure Description

However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0012] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0013] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0014] This invention provides a method for preparing a moisture-wicking and quick-drying fabric, comprising the following steps: Step S1, selecting cotton fibers and water-soluble fibers. Step S2, spinning core-spun yarn, wherein cotton fibers are the outer yarn and water-soluble fibers are the inner core yarn. Step S3, de-fibering to obtain pure cotton hollow yarn; Step S4, dehydrating, drying, and winding the pure cotton hollow yarn. Step S5, combining and twisting the wound pure cotton hollow yarn to obtain a moisture-wicking and quick-drying yarn. Step S6, re-twisting the obtained moisture-wicking and quick-drying yarn to obtain a re-twisted yarn. Step S7, weaving the fabric using a fabric weaving process, wherein a low-count, weak-twist re-twisted yarn is used as the front yarn, and a high-count, strong-twist re-twisted yarn is used as the back yarn, to weave a double-sided knitted fabric with guide grooves 2, wherein the front side is the skin-contact side.

[0015] In the preparation method of this application, when weaving the fabric using a fabric weaving process, low-count, weak-twist retwisted yarn and high-count, strong-twist retwisted yarn are used. The high-count, strong-twist retwisted yarn is used as the reverse yarn, and the low-count, weak-twist retwisted yarn is used as the front yarn. The resulting fabric is a honeycomb-shaped, textured double-sided knitted fabric, i.e., a fabric with drainage channels 2. Furthermore, the core yarn of the core-spun yarn is removed through a de-fiber process, resulting in pure cotton yarn with a hollow structure. The drainage channels 2 and the hollow structure improve the efficiency of sweat expulsion, and the cotton fibers give the fabric its softness, comfort, and moisture-wicking properties.

[0016] In one embodiment, in step S7, the low-count, weak-twist retwisted yarn has a count of 40-50S and a twist of 500T / M-800T / M; the high-count, strong-twist retwisted yarn has a count of 50-60S and a twist of 1200 T / M-1500 T / M.

[0017] If the twist and yarn count are too low, the yarn is prone to fuzzing and breakage during weaving. If the twist and yarn count are too high, the yarn strength will decrease and the dye will fade easily.

[0018] In one embodiment, in step S7, the fabric woven using a fabric weaving process has a weight of 150-200 g / m². 2 .

[0019] The higher the weight per unit area (g / m²), the greater the moisture absorption of the product; conversely, the lower the weight per unit area (g / m²), the lower the moisture absorption. Fabric weights typically range from 150-200 g / m². 2 This provides a good balance between the moisture-wicking and quick-drying properties of the yarn; beyond this range, the moisture-wicking and quick-drying properties will weaken.

[0020] In one embodiment, a single retwisted yarn comprises 4-8 pure cotton hollow yarns, with at least two of the pure cotton hollow yarns twisted in opposite directions. This design improves the stability of the yarn, making it less prone to unraveling, while exposing as many of the guide grooves 2 as possible on the outer surface of the yarn, thus improving its moisture absorption and wicking properties.

[0021] In an embodiment of the present invention, step S3 specifically includes the following steps: first, several pure cotton hollow yarns are combined on a yarn combining machine; then, at least two pure cotton hollow yarns are held at one end on a twisting machine, and the other end is rotated around the axis of the pure cotton hollow yarn itself, so that the relative rotational angular displacement is generated between the cross sections of the pure cotton hollow yarn; then, twisting is performed to obtain a moisture-wicking and quick-drying yarn.

[0022] In an embodiment of the present invention, the count of the moisture-wicking and quick-drying yarn is 40-60S, and the twist is 200 T / M-400 T / M.

[0023] In an embodiment of the present invention, in step S3, the soaking time of the core-spun yarn is 5-6 minutes, the temperature is 90-100°C, and the bath ratio of the core-spun yarn to water is 1:40.

[0024] In embodiments of the present invention, the cotton fiber is selected from Xinjiang cotton in my country, and the water-soluble fiber is selected from polyvinyl alcohol filament. The cotton fiber has a length of 32-37 mm, a micronaire value of 3.5-4.2, and a breaking strength of 35-45 cn / tex. The water-soluble fiber has a fineness of 1.2-1.65 dtex and a length of 32-38 mm.

[0025] In an embodiment of the present invention, the winding process is specifically as follows: a loose winding process is adopted, the machine speed is 900-1100m / min, and the yarn clearing channel includes N: 4.0, DS: 2.0, LS: 1.4, DL1.2, LL: 25cm, -D: -20%, -L: 15cm; the splicing parameters are 3 / 8 / 5; the pressure is 16; SFI: ±15%; VCV: ±15% / 30m.

[0026] Example 1

[0027] This embodiment provides a method for preparing a moisture-wicking and quick-drying fabric, including the following steps: Step S1: The cotton fiber is selected from Xinjiang cotton in my country, and the water-soluble fiber is selected from polyethylene glycol filament. The cotton fiber length is 32-37 mm, the micronaire value is 3.5-4.2, the breaking strength is 35-45 cn / tex, and the impurity content of the cotton fiber is within 3%. The fineness of the water-soluble fiber is 1.2-1.65 dtex, and the length is 32-38 mm.

[0028] Step S2, the process flow for spinning core-spun yarn is: opening - carding - sliver lap - doubling - combing - doubling again - doubling twice - doubling three times - roving - spinning (core-spun). The specific process for spinning is as follows: water-soluble fiber filament bobbins are arranged on the roving frame of the spinning machine, and roving is arranged on the lower frame. The traverse device of the spinning machine remains stationary. The water-soluble fibers are fed into the collector from above the rollers and combined with the drafted cotton sliver, and then twisted to form core-spun yarn.

[0029] Step S3, de-fibering, specifically involves immersing the core-spun yarn in water for 5-6 minutes at 100℃, with a yarn-to-water ratio of 1:40. After de-fibering, pure cotton hollow yarn is obtained. The cross-sectional diagram of the pure cotton hollow yarn is shown below. Figure 1 As shown.

[0030] Step S4 involves drying the pure cotton hollow yarn. The specific drying method includes: drying temperature of 60℃ and drying time of 90 minutes. After drying, the yarn is wound. The winding process includes: using a loose winding process, with a machine speed of 900-1100 m / min; yarn clearing channel: N: 4.0; DS: 2.0, LS: 1.4; DL: 1.2, LL: 25cm; -D: -20%, -L: 15cm; splicing parameters: 3 / 8 / 5; pressure: 16; SFI: ±15%; VCV: ±15% / 30m.

[0031] Step S5 involves combining and twisting the wound pure cotton hollow yarns to obtain a moisture-wicking and quick-drying yarn. The twisting process specifically includes: first, combining several pure cotton hollow yarns on a doubling machine; then, on a twisting machine, holding one end of at least two combined pure cotton hollow yarns while rotating the other end around its own axis, causing relative angular displacement between the cross-sections of the pure cotton hollow yarns, followed by twisting to form the moisture-wicking and quick-drying yarn. The moisture-wicking and quick-drying yarn has a count of 40S and a twist of 200T / M. The cross-sectional diagram of the moisture-wicking and quick-drying yarn is shown below. Figure 2 As shown.

[0032] By twisting pure cotton hollow yarns together, a guide groove 2 can be formed on the surface of the moisture-wicking and quick-drying yarn (that is, a guide groove 2 is formed between the two pure cotton hollow yarns that are twisted together). The hollow structure of the pure cotton hollow yarn can serve as a guide tube 1. The guide groove 2 and the guide tube 1 give the yarn the properties of moisture absorption and rapid conduction and diffusion.

[0033] Step S6 involves intertwining the moisture-wicking and quick-drying yarns to form a moisture-wicking and quick-drying retwisted yarn. Each retwisted yarn consists of 4-8 pure cotton hollow yarns, with at least two of them twisted in opposite directions. The resulting low-count, weak-twist retwisted yarn has a count of 40S and a twist of 600T / M; the high-count, strong-twist retwisted yarn has a count of 50S and a twist of 1200T / M. A schematic diagram of the retwisted yarn structure is shown below. Figure 3 As shown.

[0034] The retwisting process can increase the twist of the moisture-wicking and quick-drying yarn, and at the same time make the structure of the moisture-wicking and quick-drying retwisted yarn more stable.

[0035] Step S7: Use low-count, weak-twist retwisted yarn as the face yarn and high-count, strong-twist retwisted yarn as the reverse yarn to knit a honeycomb-like embossed double-sided knitted fabric. The fabric's stitch arrangement is as follows: knit stitches A, B, C, three segments forming one cycle; purl stitches A, B, C, three segments forming one cycle. Each segment completes a cycle of 20 rows, thus completing the smallest pattern. During knitting, the machine's cams are arranged according to the cam configuration table, with the total number of rows being a multiple of 20. This creates a dense, flat surface on the upper needle side and a honeycomb-like effect on the lower needle side. The cam arrangement of the honeycomb structure is shown in Tables 1 and 2 below. Figure 3 As shown. Additionally, the honeycomb weave pattern of the fabric is shown below. Figure 3The front side is the lower part of the structure. The smallest pattern cycle has 20 horizontal coil rows and 3 vertical coil rows. The 20-way structure of the first vertical coil row is as follows: the 1st, 3rd, 5th, 7th, and 19th are floating coil structure units, and the 2nd, 4th, 6th, 8th, 10th, 12th, 14th, 16th, 18th, and 20th are coil-forming structure units; the 20-way structure of the second vertical coil row is as follows: the 1st, 3rd, 5th, 7th, 9th, 11th, 13th, 15th, 17th, and 19th are floating coil structure units, and the 2nd, 4th, 6th, 8th, 10th, 12th, 14th, 16th, 18th, and 20th are coil-forming structure units; the 3rd... The 20-way structure of the coil columns is as follows: 9, 11, 13, 15, and 17 are floating coil units; 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 are coil-forming units; and 1, 3, 5, 7, and 19 are coil-packing units. The reverse side is the upper plate of the weave structure. The smallest pattern cycle has 20 coil rows and 3 coil columns. The 20-way structure of the first coil column is as follows: 2, 4, 6, 8, 9, 10, 12, 14, 16, 18, and 20 are floating coil units; and 1, 3, 5, 7, 11, 13, 15, 17, and 19 are coil-forming units; 2... The 20-channel structure of the coil column is as follows: channels 2, 4, 6, 8, 10, 12, 14, 16, 18, 19, and 20 are floating coil structure units, and channels 1, 3, 5, 7, 9, 11, 13, 15, and 17 are coiled structure units; the 20-channel structure of the third coil column is as follows: channels 2, 4, 6, 8, 9, 10, 12, 14, 16, 18, 19, and 20 are floating coil structure units, and channels 1, 3, 5, 7, 11, 13, 15, and 17 are coiled structure units.

[0036] The double-sided knitted fabric obtained by this invention achieves its honeycomb-like textured effect by relying on the loop, tuck, and float weave structures, yarn variations, and the different yarn counts on the front and back sides. The front side is the skin-contact side, which uses high-count, high-twist yarn, while the back side is the non-skin-contact side, which uses low-count, low-twist yarn. This greatly enhances the fabric's moisture absorption and wicking properties.
