Description

Technical Field

[0001] This invention relates to the field of textile fabric technology, and in particular to a double-sided fabric with a starry sky weft-knitted jacquard pattern and its preparation method. Background Technology

[0002] Currently, traditional swimwear fabrics on the market are still mainly warp-knitted and weft-knitted plain weave fabrics. In recent years, with the development of textile technology, various jacquard swimwear fabrics have also developed rapidly. Although new casual jacquard swimwear fabrics offer a variety of styles, most are just simple pattern variations with average visual effects and no impact. Furthermore, the essential structure has not changed much, meaning that the internal stretch recovery, smoothness, and impermeability remain largely unchanged, and they are relatively heavy. On the other hand, traditional warp-knitted plain weave swimwear, while some possessing excellent stretch elasticity and a sculpted appearance, results in relatively simple styles and a lack of innovation in appearance, which can lead to aesthetic fatigue among female consumers over time. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to overcome the problems of aesthetic fatigue and lack of fashion of existing warp and weft knitted plain fabric swimsuit fabrics, and the poor stretch elasticity, poor permeability and poor recovery of new casual jacquard swimsuit fabrics, and to provide a starry sky weft knitted jacquard double-sided fabric and its preparation method.

[0004] The present invention adopts the following technical solution:

[0005] This invention provides a double-sided fabric with a starry sky pattern weft-knitted jacquard, comprising a fabric body, wherein the fabric body includes a skin-friendly comfort layer and a fashionable appearance layer;

[0006] Both the skin-friendly comfort layer and the fashionable appearance layer include a main yarn and a padding yarn, which are formed by double rib knitting. The fashionable appearance layer also includes a starry sky yarn, which is formed by knitting in circles with odd-numbered needles and not knitting with even-numbered needles, as well as not knitting with odd-numbered needles and knitting with even-numbered needles.

[0007] The starry yarn is made of gold or silver thread, the main yarn is made of matte nylon yarn, and the padding yarn is made of super chlorine-resistant spandex yarn.

The first and sixth yarns are woven with starry yarn, and the second to fifth and seventh to twelfth yarns are woven with main yarn and padding yarn.

[0009] Furthermore, in the first row, the starry yarn is not knitted in loops on both the odd and even needles of the needle plate, but is knitted in loops on the odd needles of the needle cylinder and not on the even needles;

[0010] Route 6: The starry yarn is knitted without loops on both odd and even needles of the needle plate, and without loops on odd needles of the needle tube, while loops are formed on even needles.

[0011] For routes 2, 4, 7, 9, and 11, the main yarn and the padding yarn are knitted in circles on the odd-numbered needles of the needle plate and not knitted on the even-numbered needles; on the cylinder, the odd-numbered needles are not knitted and the even-numbered needles are knitted in circles.

[0012] For lines 3, 5, 8, 10, and 12, the main yarn and the padding yarn are not knitted on the odd-numbered needles of the needle plate and are knitted in circles on the even-numbered needles. On the needle cylinder, they are knitted in circles on the odd-numbered needles and are not knitted on the even-numbered needles.

[0013] Furthermore, routes 2-5 and 7-12 adopt a close-knit doffing method, with both the main yarn and the padding yarn doffed in each route.

[0014] Furthermore, the starry yarn is made of 60D gold or silver thread, the main yarn is made of 40D / 34F matte nylon FDY, and the padding yarn is made of 30D super chlorine-resistant spandex.

[0015] Furthermore, the yarn feed of the fabric body is as follows: using 100 gauge yarn, the yarn feed of the starry night yarn is 130-140mm, the yarn feed of the main yarn is 235-245mm, and the yarn feed of the padding yarn is 80-86mm.

[0016] Furthermore, the needle arrangement during fabric knitting is as follows: the needle plate is arranged with two levels of needles, 2 and 1; the needle cylinder is arranged with two levels of needles, 1 and 2, with the needle plate and needle cylinder in a needle-to-needle configuration.

[0017] This invention also provides a method for preparing a starry sky weft-knitted jacquard double-sided fabric, comprising the following steps:

[0018] 1) Yarn selection: 60D gold or silver yarn for the first and sixth yarns, and 40D / 34F matte nylon FDY yarn and 30D super chlorine-resistant Lycra spandex yarn for the second to fifth and seventh to 12th yarns.

[0019] 2) Knitting machine selection: Select a 28-needle 34-inch weft knitting double-sided circular knitting machine with a speed of (10-12) revolutions / min;

[0020] 3) Fabric weaving: In the first row, the starry yarn is woven without loops on all odd and even needles of the needle plate, and is woven in loops on odd needles of the needle cylinder, while not woven on even needles;

[0021] Route 6: The starry yarn is knitted without loops on all odd and even needles of the needle plate, and without loops on odd needles of the needle tube, while loops are formed on even needles.

[0022] For routes 2, 4, 7, 9, and 11, the main yarn and the padding yarn are knitted in circles on the odd-numbered needles of the needle plate and not knitted on the even-numbered needles; on the cylinder, the odd-numbered needles are not knitted and the even-numbered needles are knitted in circles.

[0023] For lines 3, 5, 8, 10, and 12, the main yarn and the padding yarn are not knitted on the odd-numbered needles of the needle plate and are knitted in circles on the even-numbered needles. On the needle cylinder, the odd-numbered needles are knitted in circles and the even-numbered needles are not knitted.

[0024] The fabric is obtained.

[0025] Furthermore, it also includes the dyeing and finishing process of the greige fabric: the greige fabric obtained in step 3) is washed in a flat width, pre-set, dyed on the warp beam, and then post-set to obtain the fabric body.

[0026] Furthermore, the initial shaping temperature is 195℃, the machine speed is (15-18) m / min, the width of the unwound fabric is controlled at (145-147) cm, and the basis weight is controlled at (200-205) g / m. 2 ;

[0027] The post-setting temperature is 170-180℃, the machine speed is (30-36) m / min, and the fabric specifications after finishing are 140cm×(190-195)g / m. 2 .

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] (1) The fashionable appearance layer of the fabric body in this invention includes a starry sky yarn. The starry sky yarn is made of gold or silver thread. The shimmering effect of the gold or silver thread is used. The starry sky yarn is woven in the manner of odd-numbered needle loops and even-numbered needles without weaving, and odd-numbered needles without weaving and even-numbered needles with weaving. This makes a small amount of loops and arcs exposed on the fashionable appearance layer, thus achieving the effect of a starry sky pattern. It has a strong visual impact and greatly enhances the aesthetics of the swimsuit fabric. In addition, the main yarn is matte nylon yarn. Matte FDY nylon has good smoothness, impermeability, and moisture absorption, which makes the double-sided fabric of this invention have good impermeability. The padding yarn is super chlorine-resistant Lycra spandex yarn. Whether swimming in a pool or in the sea, the fabric elasticity can be maintained and will not be damaged by chlorine water.

[0030] (2) In this invention, the yarn arrangement of the fabric body is a 12-way cycle. The first and sixth roads are woven with starry yarn, and the second to fifth and seventh to twelfth roads are woven with main yarn and padding yarn. The first road forms one of the fashionable appearance layers, the sixth road forms the second fashionable appearance layer, the second, fourth, seventh, ninth and eleventh roads form one of the skin-friendly comfort layers and the third fashionable appearance layer, and the third, fifth, eighth, tenth and twelfth roads form the second of the skin-friendly comfort layer and the fourth fashionable appearance layer, thus forming a starry visual effect. At the same time, by selecting the amount of yarn fed, the fabric body has good stretch elasticity and very good recovery.

[0031] (3) The initial shaping of the fabric in this invention uses low-tension fabric feeding and low-tension A-car rolling when the fabric is unloaded, which makes the fabric specifications stable. Silicone oil softening agent is added to the material trough in the post-shaping process, which makes the fabric smoother and more stable, and gives the fabric of this invention a special feel that is smooth on the outside and has a strong internal structure.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0038] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The invention is described in detail with specific embodiments.

[0039] This invention provides a double-sided jacquard fabric with a starry sky pattern, which can be used to make swimwear, but is not limited thereto. The double-sided fabric of this application includes a fabric body, which includes a skin-friendly comfort layer and a stylish appearance layer; both the skin-friendly comfort layer and the stylish appearance layer include a main yarn and a lining yarn, which are woven together in a double rib structure; the stylish appearance layer also includes a starry sky yarn, which is formed by knitting in loops with odd-numbered needles and leaving even-numbered needles unknitted, and by leaving odd-numbered needles unknitted and knitting even-numbered needles; the starry sky yarn is gold or silver thread, the main yarn is matte nylon yarn, and the lining yarn is super-strong chlorine-resistant spandex yarn.

[0040] The skin-friendly comfort layer of this invention is the skin-contact surface, formed by the double rib structure of the main yarn and the padding yarn, giving it characteristics such as comfort, non-irritating feel, smoothness, good breathability, and good moisture absorption. The fashionable appearance layer is formed by using a starry sky yarn, which is woven in a circular pattern with odd-numbered needles and no even-numbered needles, and vice versa. The starry sky yarn is made of gold or silver thread, giving the fabric a super visual effect of a starry night sky, giving people an extremely shocking visual impact. In addition, due to its specific use scenario, the padding yarn is made of super chlorine-resistant Lycra spandex yarn, which can maintain the elasticity of the fabric and prevent it from being damaged by chlorine water, whether swimming in a pool or in the sea.

[0041] Specifically, the fabric body is woven using a 28-needle 34-inch weft knitting double-sided circular knitting machine. The fabric body uses 2 needles and 12 yarns to form a complete cycle of pattern structure. The yarn arrangement of the fabric body is 12 yarns per cycle. The first and sixth yarns are woven with starry yarn, while the second to fifth and seventh to twelfth yarns are woven with main yarn and padding yarn, thus forming a complete pattern effect. It gives people a refreshing effect in appearance and has a strong sense of fashion and visual appeal.

[0042] Specifically, in the first row, the starry yarn is woven without loops on both the odd and even needles of the needle plate, and is woven in loops on the odd needles of the needle cylinder while not woven on the even needles, forming one of the fashionable appearance layers;

[0043] The sixth layer, the starry yarn, is woven without loops on both the odd and even needles of the needle plate, and without loops on the odd needles of the needle cylinder, while loops are woven on the even needles, forming the second layer of the fashionable appearance.

[0044] In the 2nd, 4th, 7th, 9th, and 11th rows, the main yarn and the padding yarn are woven in circles on the odd-numbered needles of the needle plate and not woven on the even-numbered needles. On the cylinder, the odd-numbered needles are not woven and the even-numbered needles are woven in circles. That is, the cylinder and needle plate are woven in circles in an alternating manner of odd and even numbered needles. Among them, the needle plate loops constitute one of the skin-friendly and comfortable layers, while the cylinder loops constitute the third of the fashionable appearance layers.

[0045] In the 3rd, 5th, 8th, 10th, and 12th rows, the main yarn and the padding yarn are not woven on the odd-numbered needles of the needle plate and are woven in loops on the even-numbered needles. On the needle cylinder, the odd-numbered needles are woven in loops and the even-numbered needles are not woven. The needle cylinder and needle plate are woven in loops with an even-odd number of needles staggered. Among them, the needle plate loops constitute one of the skin-friendly and comfortable layers, while the needle cylinder loops constitute the fourth of the fashionable appearance layers. This forms the starry sky weft-knitted jacquard double-sided fabric of the present invention.

[0046] Specifically, the 2nd to 5th and 7th to 12th rows adopt a close-knit doffing method, with each row having both main yarn and padding yarn.

[0047] Specifically, the starry sky yarn is made of 60D gold or silver thread, the main yarn is 40D / 34F matte nylon FDY, and the padding yarn is 30D super chlorine-resistant Lycra spandex. Choosing 60D silver or gold thread as the starry sky yarn provides excellent shimmering effects, and combined with the weave structure and yarn feed, achieves the starry sky pattern effect of this invention. Selecting 40D / 34F matte nylon FDY as the main yarn provides excellent smoothness, impermeability, and moisture absorption, resulting in good impermeability. Combined with certain softening agents, such as silicone-containing softeners, the invention has a smooth appearance and feel. Choosing 30D super chlorine-resistant Lycra spandex as the padding yarn provides excellent chlorine resistance, maintaining the fabric's elasticity and preventing damage from chlorine water, whether in a swimming pool or seawater.

[0048] Specifically, the yarn feed rate for the fabric body is as follows: using 100 gauge yarns, the yarn feed rate for the shimmering yarn is 130–140 mm, the main yarn feed rate is 235–245 mm, and the padding yarn feed rate is 80–86 mm. Yarn feed rates within these ranges allow the fabric to achieve a better shimmering visual effect, as well as excellent tensile elasticity and resilience.

[0049] Specifically, the needle arrangement during fabric knitting is as follows: the needle plate is arranged with two levels of needles, 2 and 1; the needle cylinder is arranged with two levels of needles, 1 and 2, with the needle plate and needle cylinder in a needle-to-needle configuration.

[0050] like Figure 3 The image provided in this application shows the finished product of the starry sky weft-knitted jacquard double-sided fabric. From the image, one can clearly feel that many stars are twinkling in the vast night sky, which is mysterious and refreshing. Unlike ordinary patterns on the market, the starry sky pattern has a stronger visual impact.

[0051] This invention also provides a method for preparing a starry sky weft-knitted jacquard double-sided fabric, comprising the following steps:

[0052] 1) Yarn selection: 60D gold or silver yarn for the first and sixth yarns, and 40D / 34F matte nylon FDY yarn and 30D super chlorine-resistant Lycra spandex yarn for the second to fifth and seventh to 12th yarns.

[0053] 2) Knitting machine selection: Select a 28-needle 34-inch weft knitting double-sided circular knitting machine with a speed of (10-12) revolutions / min;

[0054] 3) Fabric weaving: In the first row, the starry yarn is woven without loops on all odd and even needles of the needle plate, and is woven in loops on odd needles of the needle cylinder, while not woven on even needles;

[0055] Route 6: The starry yarn is knitted without loops on all odd and even needles of the needle plate, and without loops on odd needles of the needle tube, while loops are formed on even needles.

[0056] For routes 2, 4, 7, 9, and 11, the main yarn and the padding yarn are knitted in circles on the odd-numbered needles of the needle plate and not knitted on the even-numbered needles; on the cylinder, the odd-numbered needles are not knitted and the even-numbered needles are knitted in circles.

[0057] For lines 3, 5, 8, 10, and 12, the main yarn and the padding yarn are not knitted on the odd-numbered needles of the needle plate and are knitted in circles on the even-numbered needles. On the needle cylinder, the odd-numbered needles are knitted in circles and the even-numbered needles are not knitted.

[0058] The fabric is obtained.

[0059] Specifically, it also includes the dyeing and finishing process of the greige fabric: the greige fabric obtained in step 3) is washed in a flat width, pre-set, dyed on the warp beam, and then post-set to obtain the fabric body.

[0060] Specifically, after the flat-width washing is completed, a high-temperature initial setting is arranged. The initial setting temperature is 195℃, the machine speed is (15-18) m / min, the width of the fabric after the machine is controlled at (145-147) cm, and the weight is controlled at (200-205) g / m2. After the initial setting, the fabric is dyed in a warp dyeing vat. Immediately after dyeing, a post-setting is arranged, and a softening agent is added to the post-setting material tank to make the fabric smoother, more stable, and give it a certain hand feel. The post-setting temperature is 170-180℃, the machine speed is (30-36) m / min, the fabric specifications after the machine are 140cm×(190-195) g / m2, and the fabric density is cpi98-102, wpi50-54.

[0061] Through the combination and variation of the above organizational structure, yarn selection, and yarn feed amount, an initial starry sky style is formed. Then, through the special dyeing and finishing process of this invention, the finished starry sky fabric style of this invention is obtained. The finished product of this invention has at least the following advantages: a strong visual effect resembling a starry sky, a fashionable appearance, breathability and sun protection, good tensile elasticity, good recovery, strong structure, good hand feel, and superior chlorine resistance. Tested using the ISO standard tensile method BS EN 14704-1 20N, the longitudinal tensile strength is 110-130%, and the transverse tensile strength is 100-120%, with recovery rates of over 90% in both longitudinal and transverse directions at 1 minute and 30 minutes. Furthermore, tested using the ISO standard EN 13758-1:2001+A1 2006 method for testing the UV protection performance of textiles, this invention achieves a UPF of over 100 in both wet and dry states, with UVA ≤ 5%, demonstrating excellent breathability and sun protection effects.

[0062] The present invention also provides a preferred embodiment of a method for preparing a starry sky weft-knitted jacquard double-sided fabric, as detailed below:

[0063] 1) Yarn selection: 60D silver yarn for yarns 1 and 6, and 40D / 34F matte nylon FDY yarn and 30D super chlorine-resistant Lycra spandex yarn for yarns 2-5 and 7-12.

[0064] 2) Knitting machine selection: Select a 28-needle 34-inch weft knitting double-sided circular knitting machine with a speed of 10 rpm;

[0065] 3) Fabric weaving: In the first row, the starry yarn is woven without loops on all odd and even needles of the needle plate, and is woven in loops on odd needles of the needle cylinder, while not woven on even needles;

[0066] Route 6: The starry yarn is knitted without loops on all odd and even needles of the needle plate, and without loops on odd needles of the needle tube, while loops are formed on even needles.

[0067] For routes 2, 4, 7, 9, and 11, the main yarn and the padding yarn are knitted in circles on the odd-numbered needles of the needle plate and not knitted on the even-numbered needles; on the cylinder, the odd-numbered needles are not knitted and the even-numbered needles are knitted in circles.

[0068] For lines 3, 5, 8, 10, and 12, the main yarn and the padding yarn are not knitted on the odd-numbered needles of the needle plate and are knitted in circles on the even-numbered needles. On the needle cylinder, the odd-numbered needles are knitted in circles and the even-numbered needles are not knitted.

[0069] Doffing method: The 2nd to 5th and 7th to 12th rows adopt the dense doffing method, with both the main yarn and the padding yarn doffed in each row;

[0070] Yarn feed: Using 100 gauge yarn, the feed rate of the starry yarn is 130mm, the feed rate of the main yarn is 240mm, and the feed rate of the padding yarn is 80mm. This yarn selection can give the fabric a better starry visual effect as well as good stretch elasticity and recovery.

[0071] The final product is the grey fabric.

[0072] After the greige fabric is woven, it obtains the initial starry sky appearance and has a certain internal structure and tensile elasticity. Then the greige fabric undergoes dyeing and finishing. The dyeing and finishing process is as follows: greige fabric - flat-width washing (A-car roll-up) - initial setting (A-car roll-up) - dyeing (warp beam dyeing) - post-setting (A-car roll-up) - product inspection.

[0073] After the fabric is woven, it is washed in a flat width. After washing, it is rolled up using an A-series machine to prevent quality problems such as creases and scratches from appearing on the fabric surface.

[0074] After the flat-width washing is completed, a high-temperature initial setting is performed. The initial setting process is as follows: temperature is 195℃, machine speed is 18m / min, low-tension fabric feeding is used for initial setting, and low-tension A-car roll-up is used for fabric exiting the machine. This ensures the fabric specifications are stable, with the width controlled at 145cm and the weight controlled at 200g / m². 2 Because this fabric belongs to the ultra-fine matte FDY nylon fiber series, the fabric surface is more sensitive, and its quality is more difficult to control than ordinary DTY swimwear elastic fabrics. The entire fabric feeding and unfeeding process involves low-tension rolling to ensure that the fabric surface is free of bubbles and pressure marks. In addition, the initial weight of the finished product is about 5-10g heavier than the required weight of the finished product, in order to avoid the situation where the weight of the finished product is too low due to excessive rolling tension during the warp dyeing process.

[0075] After initial shaping, dyeing is arranged using a shaft dyeing vat;

[0076] After dyeing, post-setting is immediately arranged, and 10g / L of silicone oil-containing softening agent is added to the post-setting trough to make the fabric smoother and more stable, and to give the fabric of this invention a special feel that is smooth on the outside and firm on the inside. The post-setting includes the following setting parameters: temperature: 180℃, machine speed: 30m / min, and the final fabric size after finishing is 140cm*195g / m. 2 Fabric density: cpi 102, wpi 51.

[0077] Tested using the ISO standard tensile method BS EN 14704-1 20N, the longitudinal tensile strength is 110-130%, and the transverse tensile strength is 100-120%, with recovery rates of over 90% in both the longitudinal and transverse directions at 1 minute and 30 minutes. Furthermore, tested using the ISO standard EN 13758-1:2001+A1 2006 method for testing the UV protection performance of textiles, the invention achieves a UPF of over 100 in both wet and dry states, with UVA ≤ 5%, demonstrating excellent anti-penetration and sun protection effects, far exceeding relevant industry standards. Figure 3 The starry sky weft-knitted jacquard double-sided fabric prepared using this preferred embodiment has a superb visual effect.

[0078] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the nature and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention.
