Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology. Specifically, it relates to a lightweight circular knitted fabric with moisture-wicking and quick-drying composite functions. The circular knitted fabric and its weaving, dyeing and finishing process of this utility model not only have excellent moisture-wicking and quick-drying functions, but also have excellent antibacterial and bacteriostatic / UV protection composite functions. The circular knitted fabric of this utility model contains wool fibers. This utility model is particularly suitable for spring and summer knitted T-shirts and short-sleeved (POLO) shirts. Background Technology

[0002] Knitted garments worn close to the skin, such as polo shirts and T-shirts, in spring and summer not only need to have good wearing and thermal comfort properties such as soft touch, moisture absorption and wicking, quick-drying, and breathability, but also need to have multiple composite functions such as antibacterial and antimicrobial properties and UV protection to be popular with consumers.

[0003] Existing lightweight knitted clothing fabrics such as POLO shirts and T-shirts with multiple composite functions such as moisture wicking, antibacterial and antimicrobial properties are generally made directly from modified polyester fibers with irregular cross sections and functional polyester fibers with added antibacterial and antimicrobial masterbatches, or the functional polyester fibers are blended with natural fibers such as cotton and viscose with good moisture absorption, and are made through double-layer, triple-layer or integrated knitted structure design.

[0004] Alternatively, the aforementioned polo shirts, T-shirts, and other knitted garment fabrics may be prepared by applying functional finishing processes to cotton-type knitted yarns or knitted fabrics, such as moisture-wicking, quick-drying, moisture-absorbing, antibacterial, and UV-protective properties. However, fabrics that have undergone functional finishing not only have their soft feel affected, but their functionality also decreases or is lost after repeated washing.

[0005] For example, utility model patent application number "201120087509.6" discloses a knitted fabric with multiple functions including warmth retention, moisture absorption, perspiration wicking, and antibacterial properties. It includes an outer layer, a middle layer, and an inner layer. The outer and inner layers are connected by the middle layer through a double-knitted structure. The outer layer is a double-loop structure woven from hydrophilic yarn and elastic yarn. The inner layer is a double-loop structure woven from moisture-wicking yarn containing antibacterial substances and elastic yarn. The middle layer is an elastic yarn containing moisture-wicking properties. This utility model has multiple functions including warmth retention, moisture absorption, perspiration wicking, and antibacterial properties. Furthermore, the fabric has good overall elasticity and is characterized by a smooth, thick appearance and a soft hand feel.

[0006] However, the aforementioned utility model is a double-sided weft-knitted fabric made of wool yarn, modified polyester filament, and elastic yarn. The fabric is relatively thick, and its functions are warmth retention, moisture wicking (i.e., moisture-wicking function, but no quick-drying function), and antibacterial properties. Therefore, it is only suitable for autumn and winter clothing. In addition, the functional treatment of the fabric not only affects the soft touch, but also reduces or loses its functions after repeated washing.

[0007] As a knitted garment fabric for close-fitting clothing such as polo shirts and T-shirts containing wool in spring and summer, current technology typically involves interweaving wool yarn with cationic modified polyester fibers, combined with moisture-wicking finishing processes, giving the products good moisture absorption and a certain degree of quick-drying function. However, the moisture absorption and quick-drying functions of previous wool fiber fabrics and their production methods were limited (refer to the national standard GB / T21655.1-2008), and they lacked multiple functions such as antibacterial and antimicrobial properties, and UV protection.

[0008] For example, the literature "Development of Wool and Polyester Interwoven Moisture-wicking and Quick-drying Knitted Fabric, Knitting Industry, 2019(1)" discloses a double-sided fabric made of mercerized shrink-resistant wool yarn and cationic modified polyester, which has good moisture-wicking and quick-drying properties. Its moisture-wicking and quick-drying properties are represented by two indicators: the water absorption rate tested according to the AATCC standard is 1s (the standard requires ≤1s), which indicates the moisture absorption; the evaporation rate tested according to the national standard is 0.30g / h (the standard requires ≥0.18g / h), which shows better quick-drying properties. In addition, according to the national standard, moisture absorption should include three indicators: water absorption rate, wicking height, and drip diffusion time, but the water absorption rate is the most difficult to meet; quick-drying properties have two indicators: evaporation rate and moisture permeability.

[0009] The double-sided fabrics described in the aforementioned literature do not reveal or inspire the development of a lightweight circular knitted fabric containing wool, nor its weaving, dyeing, and finishing processes.

[0010] The aforementioned circular knitted lightweight fabric has a moisture-wicking and quick-drying function that fully meets national standard testing requirements, and / or has a moisture-wicking and quick-drying / antibacterial / UV protection composite function, and / or involves the use of wool fibers.

[0011] To date, no previous literature has provided a wool-containing circular knitted lightweight fabric and its weaving, dyeing and finishing process that simultaneously possesses excellent moisture absorption, quick-drying, antibacterial and UV protection functions. Utility Model Content

[0012] To overcome the above-mentioned defects, the purpose of this utility model is to provide a lightweight circular knitted fabric with moisture-wicking and quick-drying composite functions. The circular knitted fabric contains wool and has excellent moisture-wicking and quick-drying functions, as well as excellent antibacterial, bacteriostatic, and UV-protective composite functions. The circular knitted fabric and its weaving, dyeing, and finishing process of this utility model are particularly suitable for making spring and summer knitted T-shirts and short-sleeved (POLO) shirts.

[0013] The purpose of this utility model is also to provide a circular knitted fabric with multiple functions such as moisture absorption and quick drying, antibacterial and antimicrobial properties, and UV protection. The circular knitted fabric has multiple functions such as excellent moisture absorption, quick drying, antibacterial and antimicrobial properties, and UV protection. At the same time, the fabric is light, soft and breathable, and retains the luxurious soft luster of wool fibers.

[0014] Therefore, this invention achieves multiple composite functions through the optimal selection of fiber materials and the blending and interweaving of multi-component yarns. Antibacterial and bacteriostatic functions are obtained without adding any metal ions to the fiber materials, and excellent moisture absorption, quick-drying, antibacterial, bacteriostatic, and UV protection functions are achieved without any functional finishing. Compared with previous similar technologies, this invention also possesses unique advantages such as lightweight fabric, soft hand feel, and durable composite functions.

[0015] To achieve the above objectives, the technical solution of this utility model is as follows:

[0016] A lightweight circular knitted fabric with moisture-wicking and quick-drying composite functions, characterized in that:

[0017] The knitted fabric is a double-sided structure formed by two layers of interlacing in a single-sided weft plain knit weave, including:

[0018] Three-component blended yarn for use in knitted fabric yarns

[0019] Modified polyester supercool multifilament for use in ground yarn of knitted fabrics

[0020] The three-component blended yarn is composed of modified polyester supercool short fiber, wool fiber, and modal fiber in a mass ratio of 70-75%, 10-15%, and 10-15%, respectively, and is blended by Siro compact spinning process. The three-component blended yarn is then interwoven with modified polyester supercool multifilament through single-sided double-layer knitting.

[0021] The three-component blended yarn is Z-twist.

[0022] This allows the face yarn to effectively cover the ground yarn, preventing the ground yarn from showing through.

[0023] According to this invention, the modal fiber, developed by Lenzing AG of Austria, is a high-wet-modulus viscose fiber. Its dry strength is close to that of polyester, and its wet strength is superior to that of ordinary viscose fiber, thus improving the problems of low strength and low modulus of viscose fiber in a wet state. For example, modal fiber has a high wet modulus, and the yarn shrinkage rate is only about 1%, while the shrinkage rate of ordinary viscose fiber is as high as 6.5%. In addition, modal fiber has 50% higher moisture absorption and breathability than cotton fiber.

[0024] According to this utility model, its features are as follows:

[0025] Both the modified polyester supercool short fiber and the modified polyester supercool multifilament fiber have hydrophilic groups grafted onto the polyethylene terephthalate polymer chain. The fiber adopts a Y-shaped cross section, and the multi-micropore and microgroove structure on the fiber surface forms a wicking channel structure of varying sizes.

[0026] Supercool fiber incorporates hydrophilic groups through graft copolymerization onto its polymer chains. The Y-shaped cross-sectional structure of the fiber interweaves to form a network, and the micropores and microgrooves on the fiber surface create wicking channels of varying sizes, increasing the specific surface area by over 100% compared to ordinary polyester fibers. This increases both the absorbent and wicking surfaces, resulting in a single-sided, double-layer fabric structure. Combined with the capillary effect that allows sweat moisture to transfer from the inner to the outer layer, the fabric exhibits excellent moisture absorption, wicking, and quick-drying properties. When this fiber constitutes a certain mass percentage (over 70%) of the fabric, it achieves the required moisture-wicking and quick-drying functions without the need for finishing agents.

[0027] According to this utility model, its features are as follows:

[0028] The three-component blended yarn has a mass ratio of modified polyester supercool fiber, wool fiber and modal fiber of 70-75%:10-15%:10-15%.

[0029] According to this utility model, its features are as follows:

[0030] The wool fiber is 90N Merino wool fiber.

[0031] The modified polyester supercool short fiber has a fineness of 1.2 dtex and a length of 38 mm;

[0032] Modal short fibers have a fineness of 0.89 dtex to 1.67 dtex and a length of 38 mm.

[0033] As a result, the specific surface area is increased by more than 100% compared to ordinary polyester fibers, thereby increasing the moisture-absorbing and moisture-wicking surface and accelerating the evaporation of sweat.

[0034] In addition, the grafted hydrophilic groups have good antibacterial properties, and the fiber has excellent moisture absorption and quick-drying properties, creating a dry environment where bacteria cannot easily multiply, giving Supercool fabric a certain antibacterial effect. The fiber does not contain any heavy metals such as silver, and its moisture absorption, quick-drying, antibacterial and bacteriostatic functions are long-lasting.

[0035] According to this utility model, its features are as follows:

[0036] The three-component blended yarn is composed of modified polyester supercool short fiber, wool fiber, and modal fiber in a mass ratio of 75%:10%:15%, spun by Siro compact spinning process.

[0037] Explanation: (1) Considering the structure of the fiber raw materials, the moisture-wicking and moisture-absorbing properties of the ground yarn and the face yarn are different. That is, the ground yarn is a modified polyester supercool with different cross sections, which has good moisture-wicking properties, while the face yarn is a blended yarn of modified polyester supercool with different cross sections, wool fiber, and modal fiber, which has better moisture-absorbing properties than the ground yarn.

[0038] (2) From the perspective of fabric structure, the single-sided structure of the yarn-padded fabric has a double-layer effect. Single-sided structure - the fabric is light and thin; double-layer effect - after the human body sweats, the moisture-wicking and moisture-absorbing properties of the ground yarn and the face yarn are combined, the inner layer wicks moisture and the outer layer absorbs moisture, which is conducive to the transfer of moisture from the inner layer of the fabric to the outer layer of the fabric, so that the inner layer of the fabric surface always remains dry.

[0039] According to this utility model, its features are as follows:

[0040] The yarn weight ratio of the face yarn to the ground yarn is 69.5-70%: 29.5-30.5%.

[0041] According to this utility model, its features are as follows:

[0042] The loop lengths for the face yarn and the ground yarn are 15.5-16.0cm / 50 stitches and 14.8-15.3cm / 50 stitches, respectively.

[0043] Compared to single-sided fabrics, generally, the thicker the fabric, the better its UV protection. Single-sided plain knit fabrics with added yarn are thicker than ordinary single-sided plain knit fabrics. In addition, the fabric has a tighter structural parameter (the loop length of the face yarn to the ground yarn is 15.7cm / 50 stitches: 15.1cm / 50 stitches), so its UV protection is better.

[0044] According to this utility model, a part or all of the loops of a single-sided weft plain knitted fabric are formed by two or more yarns. Usually, two yarns are used for knitting. When two yarns with different twist directions are used for knitting, the phenomenon of skewed loops in the weft knitted fabric can be eliminated, and the thickness of the knitted fabric can be made uniform.

[0045] Single-sided plain knit weave is formed by continuous unit loops interlocked in one direction, creating a weave where one side is entirely front loops and the other side is entirely back loops. This weave is characterized by its lightweight fabric, pronounced curling, high unraveling tendency, good stretch, and excellent breathability. It can also create distinct front and back effects with different structures and lusters.

[0046] According to this utility model, modified polyester supercool multifilament is selected as the ground yarn, and modified polyester supercool / wool fiber / modal fiber blended yarn (75 / 10 / 15) is selected as the face yarn. This single-sided double-layer fabric structure, supplemented by the capillary effect of sweat moisture transfer from the inner layer of the fabric to the outer layer of the fabric, gives the fabric excellent quick-drying function.

[0047] The double-sided structure of the single-sided weft plain knit weave of this invention makes the fabric thin and dense, and also has UV protection function.

[0048] The lightweight circular knitted fabric with moisture-wicking and quick-drying composite functions of this utility model adopts the following weaving, dyeing and finishing process:

[0049] The greige fabric is woven on a circular knitting machine using a plain weave structure. The process involves: greige fabric → dyeing → drying → opening → setting → steaming → rolling → greige fabric finished product.

[0050] The knitted fabric is a double-sided structure consisting of a single-sided weft plain knit weave with double-layer interlacing, including:

[0051] Three-component blended yarn for use in knitted fabric yarns

[0052] Modified polyester supercool multifilament for use in ground yarn of knitted fabrics

[0053] The three-component blended yarn is composed of modified polyester supercool fiber, wool fiber, and modal fiber blended by Siro compact spinning process. The three-component blended yarn is then interwoven with modified polyester supercool multifilament by single-sided double-layer knitting.

[0054] Supercool fiber introduces hydrophilic groups through graft copolymerization onto the polymer chain. The network formed by the interlacing of the fiber's Y-shaped cross-section structure and the micropores and microgrooves on the fiber surface create wicking channels of varying sizes, increasing the specific surface area by more than 100% compared to ordinary polyester fiber.

[0055] The one-bath dyeing process for polyester using the two-bath dyeing method is as follows:

[0056] With a liquor ratio of 1:10, inject room temperature water into the high-temperature and high-pressure dyeing machine cylinder, start the main pump, and put in the fabric for circulation.

[0057] Inject into the dyeing machine cylinder:

[0058] A diluted acetic acid solution comprising 0.3% of the fabric weight.

[0059] A diluted solution of high-temperature leveling agent, comprising 0.6% of the fabric weight.

[0060] SL-376N degreasing yarn auxiliary agent with a concentration of 2 g / L.

[0061] A bath smoothing agent with a concentration of 2 g / L,

[0062] A 3% concentration of wool fiber protectant was circulated for 15 minutes.

[0063] Then inject a fully dissolved disperse dye solution, accounting for 0.4% of the fabric weight, into the dyeing machine cylinder, and heat it from room temperature to 70°C at a heating rate of 2.0°C / min, and keep it at that temperature for 10 minutes.

[0064] Heat to 110℃ at a rate of 1.5℃ / min and hold for 5 minutes;

[0065] Then increase the temperature to 130℃ at a rate of 1.5℃ / minute and hold for 30 minutes; afterwards,

[0066] Cool to 100℃ at a cooling rate of 1.5℃ / minute;

[0067] Then, sample and compare the color at a cooling rate of 2.5℃ / min to 80℃; drain the liquid after color confirmation.

[0068] The other bath dyeing process for wool and modal fibers using the two-bath dyeing method is as follows:

[0069] With a liquor ratio of 1:10, inject room temperature water into the dyeing machine's vat, start the main pump, and circulate the fabric to raise the temperature of the aqueous solution and fabric in the vat from room temperature to 40°C.

[0070] Quickly inject a solution of sodium sulfate dissolved in water (50% of the fabric weight) and acetic acid (1.5 g / L concentration) into the dyeing machine cylinder, while controlling the pH value to 4.5-5.5.

[0071] Inject a leveling agent at a ratio of 2% by weight of the fabric, circulate for 10 minutes, and then inject a fully dissolved reactive dye solution for wool at a ratio of 2.5% by weight of the fabric.

[0072] After circulating for 10 minutes, the temperature is increased from 40℃ to 60℃ at a rate of 1.5℃ / min, and held at that temperature for 60 minutes.

[0073] Take a sample for color matching. If the color is acceptable, overflow and wash for 10 minutes before draining.

[0074] The setting process is an overfeed setting process, which means that the fabric feeding speed of the setting machine is greater than the machine speed, the setting temperature is 180-190℃, the setting speed is 30-40 meters / minute, the overfeed ratio is 1%-3%, and the setting time is 40-50 seconds.

[0075] The steaming process uses a KD95 steaming machine, with steaming from the outside in for 70-80 seconds and from the inside out for 140-150 seconds, at a steam pressure of 0.09-0.10 MPa.

[0076] According to this utility model, a steaming process is added to the finishing process. The steaming process makes the fabric containing wool fibers on the surface and the high proportion of modified polyester Supercool fabric stable in shape, not easy to deform, and has a soft appearance and improves the wool-like effect. It also allows fabrics with a low proportion of wool fibers to show the texture of wool fibers and luxurious luster.

[0077] The most significant difference in the manufacturing process:

[0078] (a) Dyeing process (two-bath dyeing process): Although high temperature is required when dyeing Supercool, and wool is not resistant to high temperature, this process can still maintain the good hand feel and wool style of the fabric.

[0079] (b) Finishing process: Based on the characteristics of the ground yarn and face yarn raw materials, and combined with the size and ratio of the ground yarn loops and face yarn loops during knitting, the overfeed finishing process is determined, which can make the fabric achieve the expected fabric structure parameters and easily obtain better UV protection function.

[0080] According to this invention, a lightweight circular knitted fabric containing wool with moisture-wicking and quick-drying composite functions is disclosed. This circular knitted fabric possesses excellent moisture-wicking and quick-drying properties, as well as excellent antibacterial, bacteriostatic, and UV-protective composite functions. These multiple composite functions are achieved through the optimal selection of fiber materials and the blending and interweaving of multi-component yarns. The antibacterial and bacteriostatic functions are obtained without adding any metal ions to the fiber materials, and without any functional finishing processes. Compared to previous similar technologies, the circular knitted fabric and its weaving, dyeing, and finishing processes of this invention are particularly suitable for making spring and summer knitted T-shirts and short-sleeved (polo) shirts.

[0085] Example

[0086] A lightweight circular knitted fabric with moisture-wicking and quick-drying composite functions is prepared by: selecting 90N Merino wool fiber, conventional fine modal fiber, and modified polyester supercool fiber with a fineness of 1.2dtex and a length of 38mm, and preparing it into a 32S wool fiber / modal fiber / modified polyester supercool blended yarn by Siro compact spinning process in a mass ratio of 10:15:75.

[0087] Using this blended yarn as the face yarn, and 75D / 72F modified polyester supercool multifilament as the ground yarn, 75d / 72f indicates that the multifilament is 75 denier and consists of 72 monofilaments. The fabric is prepared using a plain weave structure on a 30-inch, 28-gauge circular knitting machine. The single-sided plain weave structure is formed by continuous unit loops interlaced in one direction, with different structures on the front and back. The front side is entirely composed of front loops, and the back side is entirely composed of back loops. This structure gives the fabric good extensibility and elasticity.

[0088] The weight ratio of face yarn to ground yarn in the fabric is controlled at 70%:30%, and the loop lengths of face yarn and ground yarn are 15.7cm / 50 stitches and 15.1cm / 50 stitches, respectively, to ensure that the face yarn loops effectively cover the ground yarn loops and prevent the ground yarn loops from showing through. The weight per square meter of the raw fabric is 165g / m². 2 ;

[0089] The above-mentioned raw fabric is processed into a finished fabric through a dyeing and finishing process of greige fabric weaving → dyeing → drying → opening → setting → steaming → rolling, wherein:

[0090] The dyeing process is a two-bath dyeing method, with one bath for dyeing modified polyester Supercool and one bath for dyeing wool and modal fibers.

[0091] A. One-bath polyester dyeing process: Bath ratio 1:10. Inject room temperature water into the dyeing machine cylinder at high temperature and high pressure, start the main pump, and circulate the fabric. Inject the dyeing machine cylinder with a 0.3% (by weight of fabric) diluted acetic acid solution, a 0.6% (by weight of fabric) diluted high-temperature leveling agent solution, a 2g / L SL-376N degreasing yarn auxiliary agent, a 2g / L bath smoothing agent, and a 3% wool fiber protectant. Circulate for 15 minutes. Add the dyeing machine cylinder... A fully dissolved disperse dye solution at 0.4% of the fabric weight is injected into the fabric. The temperature is increased from room temperature to 70°C at a rate of 2.0°C / min and held for 10 minutes; then increased to 110°C at a rate of 1.5°C / min and held for 5 minutes; then increased to 130°C at a rate of 1.5°C / min and held for 30 minutes; then decreased to 100°C at a rate of 1.5°C / min; finally, the temperature is decreased to 80°C at a rate of 2.5°C / min for color matching; after color confirmation, the solution is drained.

[0092] B. One-bath dyeing process for wool and modal fibers: liquor ratio 1:10. Inject room temperature water into the dyeing machine tank, start the main pump, and circulate the fabric to raise the temperature of the water solution and fabric in the tank from room temperature to 40°C. Quickly inject a solution of sodium sulfate dissolved at 50% of the fabric weight, with a concentration of 1.5 g / L acetic acid and a pH value controlled at 4.5-5.5, into the dyeing machine tank. Inject a leveling agent at 2% of the fabric weight. After circulating for 10 minutes, inject a fully dissolved wool reactive dye solution at 2.5% of the fabric weight. After circulating for 10 minutes, raise the temperature from 40°C to 60°C at a rate of 1.5°C / min, hold for 60 minutes, and then take a sample for color matching. If the color is qualified, overflow wash for 10 minutes and then drain the liquid.

[0093] Among them: the setting process is overfeeding setting, the setting temperature is 180-190℃, the setting speed is 30-40 m / min, the overfeeding is 1%-3%, and the setting time is 40-50 seconds;

[0094] Among them: the steaming process uses a KD95 steaming machine, with steaming from the outside to the inside for 70-80 seconds and steaming from the inside to the outside for 140-150 seconds, with a steam pressure of 0.09-0.10MPa;

[0095] The finished fabric width and weight of this invention are controlled according to the required finished width and weight, while other processes follow conventional methods; the resulting raw fabric has a width of 190cm and a weight of 220g / m². 2 .

[0096] The circular knitted fabric with moisture-wicking and quick-drying composite functions produced by the above method of this utility model was tested for moisture absorption, quick-drying, antibacterial and bacteriostatic properties, UV protection composite function, breathability, anti-pilling grade, and dimensional change rate after being left to stand for 72 hours under standard conditions, in accordance with national and industry standards. The corresponding standards and test results are shown in Table 1.

[0097] Table 1. Fabric performance test results

[0098]

[0099] According to the national standard GB / T 21655.1-2008, the moisture absorption of fabrics is expressed by three indicators (absorption rate, wicking height, and drip diffusion time), and the quick-drying property is expressed by two indicators (evaporation rate and moisture permeability). All the indicators described in this utility model are higher than the national standard values, among which the moisture permeability data is particularly important.

[0100] Compared with the prior art, the circular knitted fabric of this invention, which is suitable for spring and summer T-shirts and polo shirts, has multiple composite functions such as moisture absorption, quick drying, antibacterial and antimicrobial properties, and is lightweight, soft, breathable, and retains the luxurious soft luster of wool fibers.
