Cooling breathable moisture-absorbing and quick-drying single jacquard knitted fabric

Abstract

A cool and breathable moisture-absorbing and quick-drying single-jersey jacquard fabric is knitted by a plurality of knitted fabric units, any knitted fabric unit comprises a small unit knitted by eight yarns, the first yarn to the sixth yarn are 40S cotton and ammonia core yarns, and the seventh yarn and the eighth yarn are 60S pure cotton yarns; each of the eight yarns forms seven loop stitches, and the needle knitting arc of the seventh loop stitch is lengthened to form a three-dimensional breathable hole in the middle of adjacent small units. Through the synergistic effect of the material and the structure, the functions of "supporting elasticity" and "contacting moisture" are realized by the combination of thick / elastic yarn and thin / soft yarn; by precisely controlling the geometric shape of a specific loop (lengthening the needle knitting arc), a stable macro three-dimensional breathable structure is constructed in the fabric, effectively solving the problems of hard hand feeling, poor elasticity, poor breathability and moisture removal of traditional pure cotton fabrics, and simultaneously having the comprehensive advantages of coolness, high elasticity, breathability and quick drying.

Description

Technical Field

[0001] This application relates to the field of textile technology, specifically to a cool-feeling, breathable, moisture-wicking, and quick-drying knitted single-sided jacquard fabric. Background Technology

[0002] In the textile fabric industry, pure cotton knitted plain weave fabric is widely used in clothing production due to its good skin-friendliness. However, it has many technical defects in use, making it difficult to meet consumers' higher demands for fabric comfort, breathability and functionality.

[0003] Specifically, existing pure cotton knitted plain weave fabrics, due to their tightly packed loops, numerous interlacing points, and high yarn flexing frequency, result in a stiffer feel, lower elasticity, limited breathability, and lower heat and moisture exchange efficiency. During prolonged wear or vigorous exercise, the narrow airflow channels hinder the rapid exchange of moisture and heat between the fabric and skin, easily leading to stuffiness and a feeling of constriction, thus affecting wearing comfort.

[0004] Although there are some fabrics on the market with moisture-wicking, quick-drying, or cooling functions, most of them are made of synthetic fibers or have complex weaving structures. They still have shortcomings in material selection, structural design, or functional emphasis, and cannot take into account both the comfort of natural materials and the efficient breathability and quick-drying performance. Utility Model Content

[0005] This application provides a cool, breathable, moisture-wicking, and quick-drying knitted single-sided jacquard fabric, which effectively improves the fabric's elasticity, coolness, breathability, and moisture-wicking and quick-drying properties while ensuring the comfort of cotton.

[0006] According to one aspect of this application, one embodiment provides a cool-feeling, breathable, moisture-wicking, and quick-drying knitted single-sided jacquard fabric, which is woven in a loop from multiple knitted fabric units. Each of the knitted fabric units includes a small unit formed by knitting 8 yarns, wherein the first to sixth yarns are 40S cotton-ammonia core-spun yarn, and the seventh and eighth yarns are 60S pure cotton yarn.

[0007] Each of the eight yarns forms seven loops, and the needle-knitted arc of the seventh loop is stretched to create a three-dimensional ventilation hole between adjacent small units.

[0008] In another embodiment, the coiled coil includes a needle arc, a sinker arc, and a coil post connecting the needle arc and the sinker arc. The needle arc of the seventh coil is achieved by controlling the sinker plate to move backward a preset distance towards the center of the needle cylinder of the knitting machine.

[0009] In another embodiment, the cotton-ammonia core-spun yarn includes a core yarn and an outer covering yarn, and the cotton-ammonia core-spun yarn is formed by twisting the outer covering yarn and the core yarn.

[0010] In another embodiment, the core yarn is spandex, the cotton-covered yarn is cotton yarn, and the mass ratio of cotton to spandex in the cotton-spandex core-covered yarn is 19:1.

[0011] In another embodiment, the loop length of the yarns from the first to the sixth is 7mm-9mm / 10 needles.

[0012] In another embodiment, the loop length of the seventh and eighth yarns is 8mm-10mm / 10 needles.

[0013] In another embodiment, the length ratio of the needle arc, sinker arc and coil post of the first to sixth coils is 6-8:5-7:6-8.

[0014] In another embodiment, the length ratio of the needle arc, sinker arc, and coil post of the seventh coil is 10-14:5-7:6-8.

[0015] In another embodiment, the fabric weight is 135-140 g / m². 2 .

[0016] In another embodiment, four adjacent knitted fabric units form a large unit grid structure, with the three-dimensional ventilation holes located at the very center of the large unit grid structure.

[0017] According to the above embodiment, the cool-feeling, breathable, moisture-wicking, and quick-drying knitted single-sided jacquard fabric, because the first to sixth yarns use cotton-ammonia core-spun yarn, provides the fabric with good elasticity, overcoming the disadvantage of low elasticity of pure cotton fabric, making it more comfortable and unrestricted to wear; the seventh and eighth yarns use fine 60S pure cotton yarn, reducing the contact area with the skin and increasing the airflow space, which not only brings a cooling sensation, but also helps to quickly absorb and diffuse sweat, achieving moisture wicking and quick-drying, and avoiding a sticky feeling; by lengthening the knitting arc of specific loops, a regular three-dimensional breathable hole structure is formed on the fabric surface, which effectively accelerates air circulation, removes heat and moisture in time, and thus greatly improves the breathability and heat dissipation performance of the fabric.

[0031] In the textile fabric industry, pure cotton knitted plain weave fabric is widely used in clothing production due to its good skin-friendliness. However, it has many technical defects in use, making it difficult to meet consumers' higher demands for fabric comfort, breathability and functionality.

[0032] Specifically, existing pure cotton knitted plain weave fabrics, due to their tightly packed loops, numerous interlacing points, and high yarn flexing frequency, result in a stiff feel, low elasticity, limited breathability, and low heat and moisture exchange efficiency. During prolonged wear or vigorous exercise, the narrow airflow channels hinder the rapid exchange of moisture and heat between the fabric and skin, easily leading to stuffiness and a feeling of constriction, thus affecting wearing comfort. While some fabrics on the market offer moisture-wicking, quick-drying, or cooling properties, they often utilize synthetic fibers or complex weaving structures, and their material selection, structural design, and functional emphasis remain insufficient, failing to balance the comfort of natural materials with highly efficient breathability and quick-drying performance.

[0033] This application provides a cool, breathable, moisture-wicking, and quick-drying knitted single-sided jacquard fabric. By combining differentiated yarn material configuration with precise geometric design of the loop structure, it effectively improves the fabric's elasticity, coolness, breathability, and moisture-wicking and quick-drying properties while ensuring the comfort of cotton.

[0034] Reference Figures 1 to 3 This embodiment discloses a cool-feeling, breathable, moisture-wicking, and quick-drying knitted single-sided jacquard fabric, which is formed by multiple identical knitted fabric units 100 woven in the weft and warp directions to form a continuous fabric body; each knitted fabric unit 100 is formed by 8 yarns (i.e., Y1 to Y8) in a complete knitting cycle. The knitted fabric unit 100 presents a clear small square structure on the front side of the fabric, and each small square structure is a small unit, with four small square structures forming a large unit.

[0035] In this embodiment, please refer to Figure 3 The first to sixth yarns are made of 40S cotton-ammonia core-spun yarn, while the seventh and eighth yarns are made of 60S pure cotton yarn. Each of the eight yarns forms seven loops, and the needle-knitted arc 101' of the seventh loop 104 is stretched to form a three-dimensional ventilation hole 200 between adjacent small units.

[0036] For yarn configuration, please refer to Figure 3 The first to sixth yarns (Y1, Y2, Y3, Y4, Y5, Y6) are cotton-spandex core-spun yarns with a specification of 40S and covered with 30D spandex filaments. The cotton-spandex core-spun yarn consists of a core yarn and an outer covering yarn, which are twisted together. The core yarn is spandex, and the cotton covering yarn is cotton yarn, with a cotton to spandex mass ratio of 19:1.

[0037] In this embodiment, the thicker 40S yarn provides the main skeletal support and basic thickness of the fabric, while the spandex core yarn gives the fabric good longitudinal and transverse elastic recovery, as well as the inherent softness and skin-friendly feel of cotton fibers, providing a foundation for achieving "comfortable feel" and "unrestricted feeling".

[0038] For yarn configuration, please refer to Figure 1 and Figure 3 The 7th and 8th yarns (Y7, Y8) are made of pure cotton yarn with a specification of 60S.

[0039] In this embodiment, the finer 60S yarns mean a smaller cross-sectional area. When these fine yarns are "supported" or "elevated" within the fabric structure by adjacent coarser yarns (Y1, Y2, Y3, Y4, Y5, Y6), their actual contact area with the skin is significantly reduced. This means that the heat conduction efficiency between the fabric and the skin is reduced per unit area, resulting in a more noticeable "cooling sensation" upon initial contact. Simultaneously, it creates moisture-wicking channels, causing liquid sweat on the skin surface to tend to accumulate in areas with fewer contact points formed by the finer yarns, rather than spreading evenly between the fabric and the skin. This creates favorable conditions for the directional absorption and diffusion of sweat.

[0040] For further details, please refer to... Figure 1 and Figure 2 Each yarn (Y1-Y8) forms seven continuous loops. The loops include a needle arc 101, a sinker arc 102, and a loop post 103 connecting the needle arc 101 and the sinker arc 102. The needle arc 101' of the seventh loop 104 is achieved by controlling the sinker to move back a preset distance towards the center of the needle cylinder of the knitting machine.

[0041] In the textile industry, the needle arc 101 is a vertical segment guided by knitting needles (latch needles or hook needles), and its length control affects the longitudinal extensibility of the fabric; the sinker arc 102 is a horizontal segment guided by sinkers, and its length determines the lateral connection strength between loops; the loop post 103 is guided by both knitting needles and sinkers, and its length affects the thickness and stability of the fabric. Furthermore, the proportional relationship between the needle arc 101, sinker arc 102, and loop post 103 reflects the relative length control of each part of the loop, achieved through the coordinated movement of the knitting needles, sinkers, and guide bars.

[0042] Please refer to Figure 1 and Figure 2 The needle arc 101 is the curved portion of the loop. During knitting, the needle bends the yarn into loops by moving up and down, forming the needle arc 101. The needle hook and latch work together to ensure the yarn is correctly bent into loops. The sinker arc 102 is the extension line connecting adjacent loops. The sinker moves back and forth during knitting to assist the needle in completing the loop-forming action, ensuring the stability and uniformity of the sinker arc 102. The loop post 103 is the straight portion of the loop. The up and down movement of the needle forms the straight segment of the loop post 103, while the sinker helps to fix and guide the position of the loop post 103.

[0043] In this embodiment, please refer to Figure 1 and Figure 2In each yarn path, the needle arc 101' of the seventh loop 104 is elongated; that is, by programming and controlling the sinker of the circular knitting machine, it is moved back a preset distance towards the center of the needle cylinder when forming this loop, compared to when forming a normal loop. By moving the sinker back towards the center of the needle cylinder, the holding and pulling force of the sinker arc 102 on the yarn is reduced, so that the needle can pull up more yarn length when it rises, thereby elongating the corresponding needle arc 101', while the lengths of the sinker arc 102 and the loop post 103 remain unchanged. Since the movement trajectory of the sinker and the guide bar does not change, a three-dimensional ventilation hole 200 is finally formed.

[0044] Please refer to Figure 1 and Figure 2 The elongated knitted arc 101' appears more prominent and clear on the fabric surface, thus visually forming the side of each small square.

[0045] For further details, please refer to... Figure 1 The center points of the large unit formed by four adjacent knitted fabric units 100 (i.e., four small squares) converge into a larger area. As the elongated loops on the boundary of each unit (especially the loops forming the vertical sides) push away their adjacent loops, two prominent three-dimensional ventilation holes 200 are naturally formed in the very center of this large area.

[0046] Specifically, the 200 three-dimensional breathable holes are not formed through post-processing stamping or hollowing, but rather are three-dimensional spaces shaped in situ by the coil structure during the weaving process. These 200 holes directly penetrate both sides of the fabric, becoming highly efficient air convection and moisture dissipation channels. During exercise, air can quickly circulate through these holes, directly carrying away heat from the skin surface to enhance the cooling sensation; on the other hand, it accelerates the evaporation of sweat accumulated on the inner surface of the fabric, achieving a "quick-drying" effect.

[0047] Furthermore, the weight of the knitted single-sided jacquard fabric in this embodiment is 135-140 g / m². To achieve this optimal balance between fabric weight and performance, preferably, the loop lengths of the first to sixth rows (Y1, Y2, Y3, Y4, Y5, Y6) are controlled at 7-9 mm / 10 needles; and the loop lengths of the seventh and eighth rows (Y7, Y8) are controlled at 8-10 mm / 10 needles. This ensures that the fabric has moderate tightness, guaranteeing dimensional stability while also providing space for the formation of ventilation holes.

[0048] For further details, please refer to... Figure 1 and Figure 2For the first to sixth coils, the length ratio of the needle-knitted arc 101, sinker arc 102, and loop post 103 is preferably (6-8):(5-7):(6-8) to ensure that the fabric has a stable plain weave structure. For the elongated seventh coil 104, the length ratio of the elongated needle-knitted arc 101', sinker arc 102, and loop post 103 is preferably (10-14):(5-7):(6-8) to ensure that the corresponding needle-knitted arc 101' is effectively elongated, thereby reliably realizing its function of constructing breathable holes.

[0049] This application achieves the functions of "supporting elasticity" and "contact moisture wicking" by combining coarse / elastic yarn with fine / soft yarn through the synergistic effect of materials and structure. By precisely controlling the geometry of specific loops (elongated needle arc 101'), a stable macroscopic three-dimensional breathable structure is constructed in the fabric. Thus, when the human body sweats, the sweat is quickly absorbed by the fine cotton yarn and guided to the space supported by the coarse yarn and the three-dimensional breathable pore area 200. The increased airflow space greatly promotes the evaporation efficiency of sweat, while the airflow carries away heat, keeping the wearer dry, cool and comfortable at all times.

[0050] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
