Description

Technical Field

[0001] The present invention generally relates to the field of textile knitting technology, and in particular to a silky and breathable imitation woven jacquard fabric and a processing method thereof. Background Art

[0002] Woven fabrics are ideal for formal wear and high-end clothing due to their excellent dimensional stability and stiff texture, but they are slightly inferior to knitted fabrics in terms of breathability and comfort. With the increasing improvement of consumer concepts, traditional woven fabrics are increasingly difficult to meet consumer demand. Therefore, designing a fabric that simulates 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 discloses an elasticity-controllable imitation woven serge knitted fabric and a production method thereof, wherein the method described therein is to use cotton yarn, polyester yarn and spandex yarn as raw materials, and to weave on a circular knitting machine with a weft-knitted inlay yarn structure; the twill texture of the knitted imitation woven serge is realized through a composite structure; wherein the composite structure is a complete structure woven by a 6-way loop system, 2, 4, and 6-way loops; 1, 3, and 5-way loops + floating lines; the floating line coils are configured with cotton yarns exposed on the back side of the process as the front side of the garment, forming an imitation woven two-up and one-down twill serge; the knitted loop coils are configured with polyester and spandex exposed on the front side of the process as the back side of the garment, and the inlay yarn structure is used to form the base fabric structure, and the front side of the process is the coil surface of the polyester and spandex inlay yarn structure. The fabric of the invention has the effect of imitating woven serge fabric, and the reverse side of the process, i.e. the front side of the garment, forms an imitation woven two-upper-lower twill serge, and the front side of the process is a coil surface of a polyester and spandex added yarn structure, the surface of the fabric is flat and skin-friendly, and the preparation method is simple. Although the patent imitates the appearance of woven fabrics through loop formation and floating line structure, its surface is flat and fails to highlight the heavy and solid characteristics of woven fabrics, and the imitation woven appearance effect is poor.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] A series of simplified concepts are introduced in the Summary of the Invention, which will be further described in detail in the Detailed Description of the Invention. The Summary of the Invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the scope of protection of the claimed technical solution.

[0006] The object of the present invention is to overcome at least one defect of the above-mentioned prior art and provide a silky and breathable imitation woven jacquard fabric and a processing method thereof.

[0007] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme:

[0008] A silky and breathable imitation woven jacquard fabric, the fabric is provided with a knitted imitation woven twill pattern, and its front side presents a left twill appearance; the minimum circulation unit of the pattern consists of eight coil horizontal rows and four coil vertical rows; specifically, the first horizontal route and the fifth horizontal route are penetrated with cotton / silk blended yarn, the second horizontal route and the sixth horizontal route are penetrated with 4C groove polyester yarn, the third horizontal route and the seventh horizontal route are penetrated with cotton / silk / wool blended yarn, and the fourth horizontal route and the eighth horizontal route are penetrated with polyester / spandex core-spun yarn; the odd-numbered horizontal routes in the one circulation unit are penetrated with spun yarn, and the even-numbered horizontal routes are penetrated with filament yarn thicker than the spun yarn in the odd-numbered horizontal routes; in a three-circle organization in which three looped coils are nested, the filament yarn is looped in the middle position, and two spun yarns are looped in the upper and lower positions; in a two-circle organization in which two looped coils are nested, the filament yarn and the spun yarn are looped in the upper and lower positions, and the three-circle organization and the two-circle organization are both arranged obliquely.

[0009] Preferably, the three-loop organization adopts a single-needle double-row tuck structure to draw yarn from adjacent loops for protruding display.

[0010] Preferably, the cotton / silk blended yarn is 50s / 1-60s / 1, 90% cotton + 10% mulberry silk; the 4C groove 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; the polyester / spandex core-spun yarn is 120D-150D, 85% polyester + 15% spandex.

[0011] Preferably, the fabric is composed of 45% cotton + 41% polyester fiber + 5% mulberry silk + 5% wool + 4% spandex, and has a longitudinal density of 140 horizontal rows / 5 cm and a transverse density of 85 vertical lines / 5 cm.

[0012] A method for processing a silky breathable woven jacquard fabric, comprising the following steps: weaving→pre-setting→singeing→enzyme scouring→cold-batch alkali scouring and bleaching→chitosan modification→dehydration and drying→dyeing→singeing→softening and setting→preshrinking→finished product; wherein the woven grey cloth is the silky breathable woven jacquard fabric as claimed in any one of claims 1 to 4; the enzyme scouring and cold-batch alkali scouring and bleaching are used to remove impurities and improve the smoothness, wetting and permeability of the grey cloth, so as to facilitate subsequent dyeing; the chitosan modification comprises dipping the grey cloth in a chitosan solution twice in succession, dehydrating and drying, so as to comprehensively enhance the fiber's adsorption capacity for active dyes; the dyeing comprises three coloring processes of the grey cloth, the first coloring adopts disperse dyes, and the second and third coloring adopt heterobiactive active dyes.

[0013] Preferably, during the first dyeing, the grey cloth is immersed in the first dye solution, a low-temperature dyeing accelerator is first added, and then disperse dyes, disperse leveling agents, and wool protective agents are added, with a bath ratio of 1:20, and the pH value is adjusted to 4.5-5.5 for dyeing.

[0014] Preferably, before the second coloring, the grey cloth is first reduction cleaned, and then immersed in a second dye solution containing a heterobiactive reactive dye and a non-ionic surfactant, with a bath 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, the heating rate is 1.5°C / min, and the temperature is kept for 30-35 minutes for the second coloring.

[0015] Preferably, during the third coloring, heterobiactive reactive dyes, penetrants, wool retarder, wool protector and sodium sulfate are continuously added to the second dye liquor at a bath ratio of 1:20, and the pH value is adjusted to 11 for the third coloring.

[0016] Preferably, after the third coloring, the grey cloth is color-fixed with a formaldehyde-free color fixing agent and an anti-wrinkle finishing agent; and after water washing and ultrasonic soap washing, the cloth enters the singeing process.

[0017] Preferably, the softening and shaping is carried out by using a non-ionic silicone oil softener, and the embryo cloth is twice dipped and twice rolled before being shaped and dried, the shaping and drying temperature is 120-125° C., and the time is 40-60s.

[0018] The knitted imitation shuttle-woven twill fabric formed by the present invention has a spun yarn in an odd number of passes that is thinner than a filament yarn in an even number of passes, and at a position where three loops are nested, the filament yarn is looped at a middle position, and the loop at this position is most protruding when viewed from a cross section of the fabric, and the heights of the upper and lower spun yarn loop positions are slightly lower than the filament yarn loop positions when viewed from the cross section; and further, a single-needle double-row tuck structure is used to draw yarn from adjacent loops, so that a three-loop tissue position (light gray) where three loops are nested is more protruding than a two-loop tissue position (dark gray) where two loops are nested, so that the twill appearance of the fabric has a three-dimensional layered sense, and the three-dimensional and layered sense makes the appearance of the fabric more thick and solid visually, and the imitation shuttle-woven effect is better.

[0019] At the same time, in order to amplify this three-dimensional and layered visual effect, the present invention further adopts a targeted multi-layer piece dyeing process, utilizing the differences in the reflective effects of short-fiber blended yarn and filament yarn, looping and gathering, and cooperates with three coloring processes to form a specific shadow effect on the knitted fabric, thereby further enhancing the visual three-dimensional effect and making the imitation woven effect more realistic.

[0020] The present invention uses a variety of blended yarns with different characteristics to weave a knitted fabric with the appearance of a classic woven fabric. Through the special arrangement of looping and tucking triangles and a specific threading method, the fabric has the following advantages:

[0021] First, the short-staple yarn and the filament yarn are set at intervals to reduce the risk of snagging. Not only are the floating threads on the back side short and less likely to be snagged, but the alternating threading method of the short-staple yarn and the filament yarn separates the filament yarn loops on the front of the fabric, making it less likely to be hooked by sharp objects. Therefore, both the front and back of the fabric can effectively avoid snagging.

[0022] Second, all kinds of raw materials give full play to their performance advantages: for example, cotton, silk and wool blended yarns are comfortable to wear; 4C grooved polyester has the characteristics of moisture absorption and quick drying; cool polyester / spandex core-spun yarn can provide a cool contact function.

[0023] Third, in the process of alternating looping and tucking, the unevenness of yarn splitting and yarn bending can be shared by the upper and lower loops, which is beneficial to improving the loop uniformity of the entire knitted fabric.

[0024] The multi-component fiber of the present invention has the problem of poor dyeing homochromaticity and reproducibility in dyeing process. The inventors have selected the optimal dye combination through experiments, namely, low-temperature disperse dye + heterobiactive reactive dye for step-by-step dyeing, dyeing at a lower temperature, and saving energy. When dyeing, the polyester fiber is first dyed with an acid bath, and then the acidity and alkalinity of the dye bath are adjusted by an alkali agent, so that the reactive dye can dye the cotton, silk and wool fibers homochromatically and levelly in two steps, thereby improving the dyeing stability of various fibers.

[0025] The invention performs reduction cleaning first and then dyeing with reactive dyes after dyeing with disperse dyes, thereby solving the problem of disperse dyes staining cotton fibers and making it possible to dye polyester fibers with the same color as three natural fibers.

[0026] The fabrics mentioned in the present invention involve many types of fibers, including cotton fibers, mulberry silk fibers, sheep wool fibers, and polyester fibers, among which mulberry silk and sheep wool are protein fibers. Therefore, after multiple tests and screenings, the inventors unexpectedly discovered that heterodimer reactive dyes among reactive dyes have the best performance in dyeing homochromy of the fabrics of the present invention, and have an effect stability superior to other reactive dyes. While making the cellulose fibers and protein fibers in the fabrics show excellent dyeing homochromy, the dyeing effect also has excellent reproducibility, and has great value for industrial production application.

[0027] With the ingenious design of the present invention, a new type of knitted jacquard fabric comes into being. This fabric cleverly simulates the appearance and characteristics of woven fabrics through a unique knitting process combined with a unique dyeing process, successfully crossing the traditional boundaries between weaving and knitting in appearance and performance, and achieving a high degree of similarity in appearance imitation, which not only retains the formal beauty of woven fabrics, thick and solid, but also integrates the performance advantages of knitted fabrics, opening up new prospects for the expanded application of knitted fabrics.
