Description

Technical Field

[0001] This invention belongs to the field of textile technology, and particularly relates to a weft-knitted fabric with loops of varying lengths. Background Technology

[0002] With the continuous improvement of knitting technology and the increasing demand of consumers for functional sports fabrics, a fabric that is quick-drying, breathable, and moisture-manageable, and does not stick to the skin during exercise, is bound to be sought after by consumers.

[0003] Chinese patent publication number CN113668127A discloses a moisture-wicking, quick-drying, and antibacterial fabric. This fabric, made of bamboo yarn, fennel yarn, and Lycra spandex, is woven on a tightly knit 32-gauge loom to create a textured surface. Its advantages include greater breathability and softness compared to ordinary fabrics, as well as quick-drying and antibacterial properties. However, this fabric has a low unfilled coefficient, resulting in insufficient breathability; furthermore, the presence of cotton significantly reduces its quick-drying effect.

[0004] Chinese Patent Publication No. CN213061238U discloses a novel durable antibacterial moisture-wicking and quick-drying fabric. Through a double-sided coil structure, the outer layer uses rayon yarn, and the inner layer uses polyester yarn, achieving moisture-wicking and comfortable functions. However, the double-layer structure increases the fabric's thickness and weight, significantly impacting breathability and quick-drying properties, and cannot fully meet the requirements for ultra-fast drying, breathability, and lightweight performance during exercise.

[0005] Therefore, it is necessary to develop a lightweight fabric that is super quick-drying, highly breathable, and has good moisture management capabilities, so as to quickly wick away sweat and heat during exercise, keeping the skin dry and comfortable. Summary of the Invention

[0006] The purpose of this invention is to provide a fabric base unit that is lightweight and features super-fast drying, high breathability, and good moisture management.

[0007] Another objective of this invention is to provide a fabric pattern unit that is lightweight, quick-drying, highly breathable, and has good moisture management capabilities. Apparel made from fabrics with this fabric pattern unit can quickly wick away sweat and heat during exercise, making it particularly suitable for sportswear.

[0008] Another objective of this invention is to provide a weft-knitted fabric that is lightweight and features super-fast drying, high breathability, and good moisture management. Apparel made from this weft-knitted fabric can quickly wick away sweat and heat during exercise, keeping the skin dry and comfortable, making it particularly suitable for sportswear.

[0009] To achieve the above objectives, the present invention provides a fabric base unit with variable length loops, characterized in that it includes part A and part B, wherein part A is a base loop, and part B is a loop with variable length; the parts A and B satisfy the following formula: L = n / wpc, where L is the width of part B, n is the number of loops in part B, and WPC is the number of loop columns in part B within 1 cm; h < H < 4h, where H is the height of part B, and h is the height of part A; L Bi >L A , where L Bi L is the length of a single coil in section B. A The length of section A; the incomplete filling factor δ of the coil. B >δ A , where δ A δ is the unfilled coefficient of the coil in part A. B This is the unfilled coefficient of the coil in section B.

[0010] Compared with the prior art, the present invention has the advantage of having both a basic looped coil A portion and a looped coil B portion with varying thread lengths within a single fabric base unit, and the A portion and the B portion satisfy the following formula: L = n / wpc, where L is the width of the B portion, n is the number of loops in the B portion, and WPC is the number of rows of loops in the B portion within 1 cm; h < H < 4h, where H is the height of the B portion and h is the height of the A portion; L Bi >L A , where L Bi L is the length of a single coil in section B. A The length of section A; the incomplete filling factor δ of the coil. B >δ A , where δ A δ is the unfilled coefficient of the coil in part A. B The unfilled coefficient of the coils in section B is shown. As can be seen, the coils in section B are relatively sparse, increasing the airflow speed. Therefore, the coils in section B form windows for fabric evaporation and breathability, greatly improving the fabric's evaporation rate, breathability, and unidirectional moisture wicking ability. Furthermore, the coil length in section B is relatively longer than that in section A, resulting in a larger unfilled coefficient in section B. This makes the structure of section B more porous, thus improving fabric stability and preventing the fabric structure from becoming too loose, which is beneficial for the fabric's dimensional stability. Therefore, the fabric base unit of this invention, through the combination of sections A and B, achieves lightweight construction and features ultra-fast drying, high breathability, and excellent moisture management.

[0011] Preferably, the B portion of the fabric base unit with variable length coils of the present invention has a polygonal structure.

[0012] Preferably, the yarn in portion A of the fabric base unit with variable length loops of the present invention is the same as that in portion B. Therefore, the yarn diameter d in portion A is... A The yarn diameter d of part B B Equal, i.e., d B =d A According to the incomplete filling coefficient of the coil δ=L / d (where: L is the coil length and d is the coil diameter), in d B =d A Under the conditions, the unfilled coefficient δ of the coil of the present invention B Much greater than δ A This makes the coils in part B of the present invention more sparse than those in part A, further increasing the airflow speed and enhancing the effect of the coils in part B in forming the fabric's breathable evaporation window. This results in a further improvement in the fabric's evaporation rate, breathability, and unidirectional moisture wicking capacity. Consequently, the basic fabric unit of the present invention is made lighter, and its characteristics of ultra-fast drying, high breathability, and good moisture management are further enhanced. Therefore, fabrics with the basic fabric unit of the present invention exhibit significantly improved lightweight, quick-drying, breathability, and moisture management capabilities.

[0013] The fabric pattern unit provided by the present invention includes at least one of the aforementioned fabric base units.

[0014] The weft-knitted fabric provided by the present invention includes a plurality of the aforementioned fabric pattern units, which are arranged in a continuous and uninterrupted manner in a square pattern.

[0015] Preferably, the yarns of part A and part B of the weft-knitted fabric of the present invention are chemical fibers, natural fibers, or a blend of chemical fibers and natural fibers.

[0016] Preferably, the L of the weft-knitted fabric of the present invention A <L Bi <4L A .

[0017] Preferably, in the same row of the weft-knitted fabric of the present invention, portions A and B are arranged alternately, and the arrangement order is as follows:

[0018] X1Y1X2Y2…X n Y n

[0019] X1, X2…X n There are n coils in section A;

[0020] Y1, Y2…Y n There are n coils in section B.

[0021] Preferably, the number of loops in part A of the weft-knitted fabric of the present invention is 20:1 to 1:20.

[0022] Preferably, in each fabric pattern unit of the weft-knitted fabric of the present invention, the basic fabric unit accounts for 5% to 100% of the total number of patterns.

[0023] Compared with the prior art, the fabric pattern unit and the weft-knitted fabric having the fabric pattern unit of the present invention both have a fabric base unit including part A and part B. Since a fabric base unit simultaneously has a basic loop A and a loop B with varying yarn lengths, and the loops in part B are relatively sparse, increasing the airflow speed, the loops in part B form windows for fabric breathability and evaporation, greatly improving the evaporation rate, breathability, and unidirectional moisture wicking ability of the weft-knitted fabric of the present invention. The loop length of part B is relatively longer than that of part A, so the incomplete filling coefficient of part B is greater than that of part A, making the structure of part B more porous, thereby improving the stability of the weft-knitted fabric of the present invention, preventing the fabric structure from being too porous, and contributing to the dimensional stability of the fabric. Therefore, the fabric pattern unit and the weft-knitted fabric having the fabric pattern unit of the present invention achieve their benefits through the combination of part A and part B. It achieves lightweight fabric pattern units and weft-knitted fabrics with these fabric pattern units, and features super-fast drying, high breathability and good moisture management. At the same time, it enables clothing made from this weft-knitted fabric to quickly wick away sweat and heat during exercise, keeping the skin dry and comfortable, making it especially suitable for sportswear.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Embodiments of the present invention will now be described with reference to the accompanying drawings, in which similar element reference numerals represent similar elements.

[0032] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] The weft-knitted fabric of the present invention comprises a plurality of fabric pattern units, which are arranged in a continuous and uninterrupted manner in the weft-knitted fabric of the present invention. At least one path of the fabric pattern unit of the present invention has a fabric base unit; that is, within a cycle of one fabric pattern unit, at least one path of the weft-knitted fabric of the present invention includes a plurality of fabric base units. The fabric base unit of the present invention has a loop of varying length. (The following is in conjunction with...) Figure 1 The fabric base unit with variable length coils of the present invention will be described in detail below:

[0034] like Figure 1As shown, the fabric base unit with variable length coils of the present invention includes part A and part B. Part A is a basic looped coil, and part B is a looped coil with variable length. Part A and part B satisfy the following formula: L = n / wpc, where L is the width of part B, n is the number of coils in part B, and WPC is the number of rows of coils per centimeter (WPC) in part B within 1 cm; h < H < 4h, where H is the height of part B and h is the height of part A; L Bi >L A , where L Bi L is the length of a single coil in section B. A The length of section A; the incomplete filling factor δ of the coil. B >δ A , where δ A δ is the unfilled coefficient of the coil in part A. B This represents the incomplete filling coefficient of the coils in section B. Therefore, this invention, because a single fabric base unit simultaneously contains a basic looping coil section A and a looping coil section B with varying thread lengths, and sections A and B satisfy the following formula: L = n / wpc, where L is the width of section B, n is the number of coils in section B, and WPC is the number of coil columns within 1 cm in section B; h < H < 4h, where H is the height of section B, and h is the height of section A; L Bi >L A , where L Bi L is the length of a single coil in section B. A The length of section A; the incomplete filling factor δ of the coil. B >δ A , where δ A δ is the unfilled coefficient of the coil in part A. B The unfilled coefficient of the coils in section B is shown. As can be seen, the coils in section B are relatively sparse, increasing the airflow speed. Therefore, the coils in section B form windows for fabric evaporation and breathability, greatly improving the fabric's evaporation rate, breathability, and unidirectional moisture wicking ability. Furthermore, the coil length in section B is relatively longer than that in section A, resulting in a larger unfilled coefficient in section B. This makes the structure of section B more porous, thus improving fabric stability and preventing the fabric structure from becoming too loose, which is beneficial for the fabric's dimensional stability. Therefore, the fabric base unit of this invention, through the combination of sections A and B, achieves lightweight construction and features ultra-fast drying, high breathability, and excellent moisture management.

[0035] like Figure 1 As shown, preferably, the B portion of the fabric base unit with variable length coils of the present invention has a polygonal structure.

[0036] Preferably, the yarn in portion A of the fabric base unit with variable length loops of the present invention is the same as that in portion B. Therefore, the yarn diameter d in portion A is... A The yarn diameter d of part B B Equal, i.e., d B =d A According to the incomplete filling coefficient of the coil δ=L / d (where: L is the coil length and d is the coil diameter), in d B =d A Under the conditions, the unfilled coefficient δ of the coil of the present invention B Much greater than δ A This makes the coils in part B of the present invention more sparse than those in part A, further increasing the airflow speed and enhancing the effect of the coils in part B in forming the fabric's breathable evaporation window. This results in a further improvement in the fabric's evaporation rate, breathability, and unidirectional moisture wicking capacity. Consequently, the basic fabric unit of the present invention is made lighter, and its characteristics of ultra-fast drying, high breathability, and good moisture management are further enhanced. Therefore, fabrics with the basic fabric unit of the present invention exhibit significantly improved lightweight, quick-drying, breathability, and moisture management capabilities.

[0037] Preferably, the yarns of part A and part B of the weft-knitted fabric of the present invention are both chemical fibers, natural fibers, or a blend of chemical fibers and natural fibers.

[0038] Preferably, the L of the weft-knitted fabric of the present invention A <L Bi <4L A .

[0039] Preferably, in the same row of the weft-knitted fabric of the present invention, portions A and B are arranged alternately, and the arrangement order is as follows:

[0040] X1Y1X2Y2…X n Y n

[0041] X1, X2…X n There are n coils in section A;

[0042] Y1, Y2…Y n There are n coils in section B.

[0043] Preferably, the ratio of the number of loops in portion A to the number of loops in portion B of the weft-knitted fabric of the present invention is 20:1 to 1:20. Further, the ratio of the number of loops in portion A to the number of loops in portion B of the present invention is 10:1 to 1:10.

[0044] Preferably, in each fabric pattern unit of the weft-knitted fabric of the present invention, the basic fabric unit accounts for 5% to 100% of the total number of patterns. Further, in each fabric pattern unit of the weft-knitted fabric of the present invention, the basic fabric unit accounts for 20% to 100% of the total number of patterns.

[0045] Combination Figure 1 - Figure 4 As shown, the present invention is specifically designed for weaving the aforementioned weft-knitted fabrics using a circular knitting machine, including a first triangle for forming part A. Figure 3 As shown), the first blocking triangle has a standard circular triangle structure (i.e., a normal circular triangle structure), and also includes a second blocking triangle for forming part B. Figure 4 As shown), the second-position triangle has a deep presser point loop structure relative to the first-position triangle; the first-position triangle and the second-position triangle satisfy the following formula: γ2>γ1, H2>H1, where γ1 is the presser angle of the first-position triangle, γ2 is the presser angle of the second-position triangle, H1 is the yarn bending depth of the first-position triangle, and H2 is the yarn bending depth of the second-position triangle. More specifically, the needle count of the weft knitting circular knitting machine of the present invention is 8G-54G. Therefore, this invention is a circular knitting machine specifically designed for weft-knitted fabrics. The first triangle forms part A, and the second triangle forms part B. The loop length of part B is relatively longer than that of part A, resulting in a higher unfilled coefficient for part B than for part A. This makes the structure of part B more porous, leading to lightweight weft-knitted fabrics produced by this circular knitting machine. These fabrics also feature super-fast drying, high breathability, and excellent moisture management. Apparel made from this weft-knitted fabric can quickly wick away sweat and heat during exercise, keeping the skin dry and comfortable, making it particularly suitable for sportswear.

[0046] The following combination Figure 1 - Figure 7 A detailed description is provided for one embodiment of the weft-knitted fabric of the present invention:

[0047] This embodiment requires the design of an ultra-quick-drying, breathable, lightweight T-shirt fabric with a heather gray effect, approximately 130 GSM, and a width of 155 cm.

[0048] I. Yarn Selection:

[0049] The yarns used are: Yarn 1: PES 100D / 144D / SD DTY, Yarn 2: CDP / PES 100D / 144F / SDFDDTY, and polyurethane elastic fiber PU 30D (30D spandex) is also used to increase elasticity.

[0050] II. Pattern Selection: Part A is the basic coiled coil, and Part B is a coiled coil with varying line lengths.

[0051] To increase the fabric's breathability and evaporation rate, the number of loops containing part A (basic looped coils, often referred to in this field as coils of normal length) and part B (looped coils of varying lengths) is arranged in a 1-to-1 alternating pattern with other loops excluding part B; and all other loops excluding part B are composed of part A. In the loops containing part B, the ratio of the number of loops in part A to part B is 1:5.

[0052] III. Models Used:

[0053] The specific machine selection is as follows: This invention is a weft knitting circular knitting machine specifically designed for weaving weft-knitted fabrics containing parts A and B, modified from an existing weft knitting single-sided circular knitting machine. The weft is 32G and the machine is 34 inches.

[0054] The following are methods for modifying existing weft knitting single-sided circular knitting machines:

[0055] a. Modification of the yarn feeding device. For routes containing section B (variable yarn length looped coils), the yarn feeding method is changed from active to passive. Therefore, all yarn feeding devices for these routes are modified to passive yarn feeding devices. For details of the specific yarn feeding method in this embodiment, please refer to [link to specific example]. Figure 5 As shown.

[0056] b. Modification of the cam. To have both part A and part B on the same path, two or more different heel positions of needles must be used. There must be two or more cam positions corresponding to the yarn on this path. One of these cam positions consists of a standard loop-forming cam (i.e., the first cam position of this invention). The loop formed by the needles passing through this first cam position is the loop of part A (the basic loop-forming loop). The basic motion trajectory of the needles passing through this first cam position is shown in the diagram below. Figure 2 As shown; at least one of the cams is modified into the second cam of this invention, and the loop formed by the needle through this second cam is the loop of part B (a loop with varying thread length). The basic motion trajectory of the needle through this second cam is shown in the diagram. Figure 3 As shown, the second triangle is a deep presser point forming triangle. The presser point of its rhombus is relatively deeper than that of part A. In addition, this path adopts a passive yarn feeding method. The presser point is at the bottom, and the presser angle γ2 > γ1, which means that the yarn bending depth is greater, that is, H2 > H1, that is, the loop length is longer. Therefore, the loop formed by the knitting needle running on the track is the loop of part B.

[0057] IV. Weaving process:

[0058]

[0059] V. Knitting Pattern: such as Figure 4 As shown.

[0060] VI. Rhombus Diagram: such as Figure 5As shown.

[0061] 7. Needle arrangement: 1 2 2 2 2 2 2 2 2 2 2 2.

[0062] VIII. Actual finished product data: Width: 155cm, Weight: 130GSM, Horizontal density: 21, Vertical density: 23.5.

[0063] IX. Test data, combined with Figure 6 and Figure 7 As shown:

[0064] a. Evaporation rate. Tested according to GB / T 21655.1-2008 standard; evaporation rate: 0.45 g / h before washing, 0.48 g / h after 5 water washes.

[0065] b. Water diffusion time. Tested according to GB / T 21655.1-2008 standard; water diffusion time before washing: <1 second, after 5 washes: <1 second.

[0066] c. Breathability. Tested according to GB / T 5453 standard; breathability reaches 1300mm / s.

[0067] d. One-way transport capability (OWTC). Tested according to AATCC 195, "Liquid Moisture Management Properties of Textile Fabrics"; the one-way transport capability (OWTC) of the fabric measured in this study was 153%.

[0068] Based on comprehensive test results, the weft-knitted fabric of the present invention has an ultra-high evaporation rate, good breathability, and one-way moisture wicking capability, thereby making the weft-knitted fabric of the present invention lightweight and having the characteristics of ultra-fast drying, high breathability, and good moisture management.

[0069] Combination Figure 1 - Figure 7As shown, compared with the prior art, the fabric pattern unit and the weft-knitted fabric having the fabric pattern unit of the present invention both have a fabric base unit including part A and part B. Since a fabric base unit simultaneously has a basic loop A and a loop B with varying thread lengths, and the loops in part B are relatively sparse, increasing the airflow speed, the loops in part B form a window for fabric breathability and evaporation, greatly improving the evaporation rate, breathability, and unidirectional moisture wicking ability of the weft-knitted fabric of the present invention. Furthermore, the loop length of part B is relatively longer than that of part A, so the incomplete filling coefficient of part B is greater than that of part A, making the structure of part B more porous. This improves the stability of the weft-knitted fabric of the present invention, prevents the fabric structure from being too porous, and is beneficial to the dimensional stability of the fabric. Therefore, the fabric pattern unit and the weft-knitted fabric having the fabric pattern unit of the present invention achieve their benefits through the combination of part A and part B. It achieves lightweight fabric pattern units and weft-knitted fabrics with these fabric pattern units, and features super-fast drying, high breathability and good moisture management. At the same time, it enables clothing made from this weft-knitted fabric to quickly wick away sweat and heat during exercise, keeping the skin dry and comfortable, making it especially suitable for sportswear.

[0070] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims. Furthermore, the embodiments disclosed above are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Therefore, equivalent variations made within the scope of the claims are still within the scope of the present invention.
