Description

Technical Field

[0001] This invention generally relates to the field of textile and knitting technology, and more specifically, to a silky, breathable imitation woven jacquard fabric and its processing method. Background Technology

[0002] Woven fabrics, with their excellent dimensional stability and crisp texture, are an ideal choice for making formal wear and high-end clothing. However, they are slightly inferior to knitted fabrics in terms of breathability and comfort. As consumer awareness continues to rise, traditional woven fabrics are finding it increasingly difficult to meet consumer demands. Therefore, designing a fabric that mimics the appearance and characteristics of woven fabrics while retaining the performance advantages of knitted fabrics has become a new path for the design and development of knitted fabrics.

[0003] For example, Chinese patent CN114892329A describes an elastic, controllable imitation woven serge knitted fabric and its production method. The method involves using cotton yarn, polyester yarn, and spandex yarn as raw materials, and weaving them on a circular knitting machine using a weft-knitted yarn-adding structure. A composite structure is used to achieve the twill texture of the imitation woven serge. The composite structure consists of a 6-way loop system knitting a complete structure, with loops 2, 4, and 6; loops 1, 3, and 5 + floats; the float loops are configured with cotton yarn exposed on the reverse side of the process as the wearing side, forming an imitation woven two-up-one-down twill serge; the knitted loops are configured with polyester and spandex exposed on the wearing side of the process, forming the base fabric structure using the yarn-adding structure, and the processing side is the loop surface of the polyester and spandex yarn-adding structure. The fabric of this invention has the effect of imitating woven serge fabric. On the reverse side (the wearing side), a woven two-up-one-down twill serge pattern is formed, while the wearing side is a looped surface with polyester and spandex yarns. The fabric surface is smooth and skin-friendly, and the manufacturing method is simple. Although this patent imitates the appearance of woven fabric through loop and float structures, its smooth surface fails to highlight the thickness and sturdiness of woven fabric, resulting in a poor imitation woven appearance. It should be noted that the information disclosed in the above background section is only used to enhance the understanding of the background of this disclosure and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] The purpose of this invention is to overcome at least one of the defects of the prior art and to provide a silky and breathable imitation woven jacquard fabric and its processing method.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A silky and breathable imitation woven jacquard fabric is provided, wherein the fabric features a knitted imitation woven twill pattern, with a left twill appearance on the front. The smallest repeat unit of the pattern consists of eight horizontal rows and four vertical rows of loops. Specifically, the first and fifth horizontal rows are threaded with cotton / silk blended yarn, the second and sixth horizontal rows are threaded with 4C grooved polyester yarn, the third and seventh horizontal rows are threaded with cotton / silk / wool blended yarn, and the fourth and eighth horizontal rows are threaded with polyester / spandex core-spun yarn. In each repeat unit, odd-numbered horizontal rows are threaded with short-fiber yarn, and even-numbered horizontal rows are threaded with filament yarn that is thicker than the short-fiber yarn in the odd-numbered horizontal rows. In a three-loop structure with three nested loops, the filament yarn is looped in the middle position, and the two short-fiber yarns are looped at the top and bottom positions. In a two-loop structure with two nested loops, the filament yarn and the short-fiber yarn are looped at the top and bottom positions. Both the three-loop and two-loop structures are arranged diagonally.

[0007] Preferably, the three-loop weave employs a single-needle double-row tufting structure, where yarn is pulled from adjacent loops to create a protruding display.

[0008] Preferably, the cotton / silk blended yarn is 50s / 1-60s / 1, 90% cotton + 10% mulberry silk; the 4C grooved polyester yarn is 120D-150D, 100% polyester; the cotton / silk / wool blended yarn is 50s / 1-60s / 1, 70% cotton + 20% mulberry silk + 10% wool; and the polyester / spandex core-spun yarn is 120D-150D, 85% polyester + 15% spandex.

[0009] Preferably, the fabric is composed of 45% cotton, 41% polyester fiber, 5% silk, 5% wool, and 4% spandex, with a warp density of 140 rows / 5cm and a weft density of 85 rows / 5cm.

[0010] A processing method for a silky breathable imitation woven jacquard fabric includes the following steps: weaving → pre-setting → singeing → enzyme scouring → cold alkali scouring and bleaching → chitosan modification → dehydration and drying → dyeing → singeing → softening and setting → pre-shrinking → finished product; wherein, the fabric obtained by weaving is the silky breathable imitation woven jacquard fabric as described in any one of claims 1-4; the enzyme scouring and cold alkali scouring and bleaching are used to remove impurities and improve the smoothness, wetting, and penetration properties of the fabric to facilitate subsequent dyeing; the chitosan modification includes immersing the fabric in chitosan solution twice, followed by dehydration and drying, to comprehensively enhance the fiber's adsorption capacity for reactive dyes; the dyeing includes three dyeing processes for the fabric, with the first dyeing using disperse dyes, and the second and third dyeing using heterodireactive dyes.

[0011] Preferably, during the first dyeing, the greige fabric is immersed in the first dyeing liquor, a low-temperature dyeing accelerator is added first, followed by disperse dye, dispersion leveling agent, and wool protectant, with a liquor ratio of 1:20, and the pH value is adjusted to 4.5-5.5 for dyeing.

[0012] Preferably, before the second dyeing, the fabric is first subjected to reduction cleaning, and then the fabric is immersed in a second dyeing solution containing a heterodiactive reactive dye and a nonionic surfactant at a liquor ratio of 1:20, and the pH value is adjusted to 5; after stirring, sodium sulfate is added, the temperature is raised to 60°C at a rate of 1.5°C / min, and the temperature is maintained for 30-35 minutes for the second dyeing.

[0013] Preferably, during the third dyeing process, anisodiactive reactive dye, penetrant, wool retarder, wool protectant, and sodium sulfate are added to the second dyeing solution at a liquor ratio of 1:20, and the pH value is adjusted to 11 for the third dyeing.

[0014] Preferably, after the third coloring, a formaldehyde-free color-fixing agent and an anti-wrinkle finishing agent are used to fix the color of the fabric; after water washing and ultrasonic soaping, it enters the singeing process.

[0015] Preferably, the softening and shaping process involves using a nonionic silicone oil softener, followed by two impregnations and two rolls of the fabric, and then shaping and drying at a temperature of 120-125°C for 40-60 seconds.

[0016] The knitted twill fabric formed by this invention uses finer short-fiber yarns in odd-numbered loops than filament yarns in even-numbered loops. At positions with three nested loops, the filament yarn loops in the middle, and this loop is most prominent when viewed in cross-section. The two short-fiber yarn loops above and below this position are slightly lower in height when viewed in cross-section than the filament yarn loop position. Furthermore, by utilizing a single-needle double-row tucking structure to pull yarn from adjacent loops, the three-loop structure position (light gray) with three nested loops is more prominent than the two-loop structure position (dark gray) with two nested loops, giving the twill fabric a three-dimensional, layered appearance. This three-dimensionality and layering make the fabric appear heavier and more solid, resulting in a better woven-like effect.

[0017] Meanwhile, to amplify this three-dimensional and layered visual effect, the present invention further employs a targeted multi-layered dyeing process. By utilizing the differences in reflective effects between short-fiber blended yarn and filament yarn, and between looped and tucked loops, and combining this with a three-stage dyeing process, a specific shadow effect is formed on the knitted fabric, further enhancing the three-dimensional visual effect and making the imitation woven effect more realistic.

[0018] This invention uses a variety of blended yarns with different properties to weave a knitted fabric with the appearance of a classic woven fabric. Through a special arrangement of loops and tucked triangles, combined with a specific yarn-threading method, the fabric has the following advantages: First, the alternating arrangement of short-fiber yarn and filament yarn reduces the risk of snagging. Not only are the short floats on the reverse side less prone to snagging, but the alternating weaving of short-fiber yarn and filament yarn also keeps the filament yarn loops on the front side of the fabric apart, making it less likely to be snagged by sharp objects. Therefore, snagging can be effectively avoided on both the front and back sides of the fabric.

[0019] Secondly, various raw materials fully utilize their performance advantages: for example, cotton, silk, and wool blended yarns are comfortable to wear; 4C grooved polyester has moisture-wicking and quick-drying properties; and cool-feeling polyester / spandex core-spun yarn can provide a cooling sensation upon contact.

[0020] Third, during the alternation of looping and gathering, the unevenness of yarn splitting and bending can be shared by the upper and lower loops, which helps to improve the loop uniformity of the entire knitted fabric.

[0021] This invention addresses the problem of poor color uniformity and reproducibility in the dyeing process of multi-component fibers. Through experimentation, the inventors selected the optimal dye combination: a step-by-step dyeing process using low-temperature disperse dyes and heterodi-reactive dyes. This lower temperature dyeing method saves energy. During dyeing, polyester fibers are first dyed in an acid bath, and then the acidity / alkalinity of the dye bath is adjusted using an alkali agent. This two-step process achieves uniform and even dyeing of cotton, silk, and wool fibers with reactive dyes, improving the dyeing stability of various fibers.

[0022] This invention solves the problem of staining cotton fibers with disperse dyes by first reducing and cleaning them after dyeing with disperse dyes and then dyeing them with reactive dyes, making it possible to dye polyester fibers the same color as the three natural fibers.

[0023] The fabrics mentioned in this invention involve a variety of fibers, including cotton, silk, wool, and polyester. Silk and wool are protein fibers. After numerous trials and screenings, the inventors unexpectedly discovered that amphoteric reactive dyes exhibited the best color matching in the fabrics of this invention, demonstrating superior stability compared to other reactive dyes. This not only ensures excellent color matching for both cellulose and protein fibers in the fabric but also provides excellent reproducibility, making it highly valuable for industrial production. Through the ingenious design of this invention, a novel knitted jacquard fabric has emerged. This fabric, through a unique knitting and dyeing process, cleverly simulates the appearance and characteristics of woven fabrics, successfully transcending the traditional boundaries between woven and knitted fabrics in terms of appearance and performance. Particularly noteworthy is its high degree of similarity in appearance imitation. It not only retains the aesthetic appeal and robustness of woven fabrics but also incorporates the performance advantages of knitted fabrics, opening up new prospects for the expanded application of knitted fabrics.
