Description

Technical Field

[0001] This invention relates to the field of fabric weaving technology, specifically a jacquard fabric production process. Background Technology

[0002] Qi Wan refers to the fine white silk produced in the ancient Qi region, its name originating from the delicate and lustrous white silk "Wan" produced in Linzi. In modern times, it generally refers to precious silk fabrics. Modern Qi Wan jacquard weaving techniques, while inheriting tradition, continuously integrate new technologies and design concepts, achieving significant development in raw materials, processes, equipment, and application areas. Sangbo Satin is a type of Qi Wan silk jacquard fabric, referring to a weaving method where warp and weft threads are arranged according to specific rules, floating or interwoven on the surface of the silk fabric to form patterns or designs. Sangbo Satin products are characterized by clear satin texture, an antique feel, various woven patterns, and a very noble appearance. The fabric is thicker than georgette, relatively soft, opaque, has a low depreciation rate after washing, is not easily faded, and has vibrant colors. It is commonly used in home textiles (such as bedding and sofa fabrics) and high-end fashion fabrics.

[0003] Satin jacquard fabrics come in a variety of patterns and have a complex manufacturing process. The production of Satin jacquard products requires more than a dozen major processing steps, including raw material inspection (selection), soaking, drying, winding, doubling, twisting, setting (steaming), warping, reed binding, weaving, inspection, and finishing. However, in the production of this type of all-silk jacquard fabric, because the raw materials are all the same type of silk, the performance is limited and the expressive power is weak. This results in a lack of three-dimensionality in the woven jacquard fabric and a relatively flat pattern presentation.

[0004] Furthermore, since the uniformity of warp and weft threads in jacquard fabrics directly affects the three-dimensionality of the pattern, the doubling machine can only ensure the perfect presentation of this characteristic through a stable doubling process. During the doubling process, the tension of multiple monofilaments is controlled synchronously, which can eliminate defects such as coarse knots and uneven tension in the original yarns, making the linear density of the combined yarns more uniform. In jacquard fabric weaving, uniform linear density is the key to ensuring the clarity of the jacquard pattern. Reducing manual intervention and operation based solely on experience in the doubling process, and providing standardized or automated operation capabilities for equipment, can significantly improve production efficiency, reduce costs, optimize product quality, and enhance operational safety. However, existing silk doubling machines still require manual operation based solely on experience in stages such as loading, clamping, thread catching, and unloading, which makes it difficult to guarantee the operating efficiency and quality of the doubling machine, and will further affect the color expression of the jacquard fabric. Summary of the Invention

[0005] The purpose of this invention is to provide a jacquard fabric production process to address the technical problems mentioned in the background art.

[0010] Use a doubling machine to doubling the weft yarn: doubling speed 350-400m / min, doubling tension 10-15g, and the lower the relative humidity, the better;

[0011] Step 5: Twisting the silk;

[0012] The warp yarn is twisted using a doubling machine at a spindle speed of 5300-5500 r / min, a twist of 230-250 T / m, and a twist tension of 8-10 g. The relative humidity in the twisting area is controlled between 70-75%.

[0013] The weft yarn is twisted using a doubling machine at a spindle speed of 7000-7200 r / min, twist of 2200 T / m, Z / S twist direction, and twist tension of 15-20 g. Since the yarn needs to be protected from moisture and kept dry, the lower the relative humidity, the better.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. The jacquard product Mulberry Satin described in this invention uses mulberry silk as the warp and matte rayon as the weft. Furthermore, the warp and weft are pre-treated according to the characteristics of the silk threads and the requirements of use, so that the jacquard pattern can better reflect the beauty on the silk fabric, with obvious alternation of light and dark colors and three-dimensional patterns, thus solving the problems of the single raw material and insufficient color expression of jacquard products.

[0031] 2. This invention designs a twinning machine for improved process matching. The twinning machine, through the setting of an installation mechanism, places the roll between two extrusion columns. Rotating the rotating column drives the toothed rod to move, and the two toothed rods move closer to each other. The two extrusion columns move and insert into both ends of the roll to clamp it. After completion, the fixing block is released, and the fixing block is engaged into the fixing groove by the elastic force of the first spring, fixing the rotating column and thus fixing the position of the roll. This facilitates the quick installation and disassembly of the roll and facilitates subsequent processing operations.

[0032] 3. The spinning machine is equipped with a rotating mechanism that pushes the rotating plate downwards. The rotating plate rotates and causes the roll to press against the rotating roller. The rotating roller rotates and drives the third bevel gear to rotate through the helical teeth. The rotation of the third bevel gear drives the rotating rod to rotate through the horizontal plate. The rotation of the rotating rod drives the extrusion column to rotate. The rotation of the extrusion column drives the roll to rotate synchronously. This makes it easy for the roll to rotate together with the rotating roller to wind up the yarn. This avoids the roll width from gradually increasing due to the increase of yarn on the roll, which would cause the roll to separate from the rotating roller and affect the rotation of the roll.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0045] In this embodiment of the invention, a jacquard fabric production process includes the following steps:

[0046] Step 1: Raw material selection; Select 2 / 20 / 22D mulberry silk as the warp, select 1 / 75D matte rayon as the weft, and select five-end satin as the basic structure of the fabric.

[0047] Step 2: Soaking the yarn; the bath ratio of the warp yarn to the soaked yarn is 1:5, and the mass ratio of the soaking agent is agent: yarn = 7.5:90. The water temperature is 40-42 degrees Celsius, and the soaking time is 45 minutes; the weft yarn is 1 / 75D matte rayon, which does not require soaking.

[0048] The foaming agent selected is EKL-300A high-speed additive produced by Hangzhou Xinyinglun Technology Co., Ltd., which has the following characteristics:

[0049] 1) It gives raw silk excellent smoothness, superior softness, good antistatic properties, and mildew resistance;

[0050] 2) It imparts excellent strength to raw silk, enhancing its elongation and cohesion;

[0051] 3) The coloring is even during soaking, and it is easy to thoroughly clean during refining.

[0052] Step 3: Winding; Use the GD001-145 winding machine produced by Hangzhou Textile Machinery to wind the warp yarns: winding speed 130-140m / min, winding tension 5-15g, and relative humidity of the winding area controlled between 60-65%; the weft yarn is 1 / 75D dull rayon, which does not require winding.

[0053] Step 4: Doubling the warp threads; use the improved doubling machine to doubling the warp threads: doubling speed 350-4000m / min, doubling tension 6-8g, of which the tension of a single filament is 3g, and the relative humidity of the warp thread doubling area is controlled between 60-65%.

[0054] The improved doubling machine is used to doubling the weft yarn: the doubling speed is 350-400m / min and the doubling tension is 10-15g. Because the strength of the rayon raw material decreases significantly after absorbing moisture, and it is easy to break and the weft yarn comes out of the tension, the rayon doubling area should be kept dry and the relative humidity should be as low as possible.

[0055] Step 5: Twisting the silk;

[0056] The R362 / S double twister manufactured by the Italian company Latti was selected to twist the warp yarn at a spindle speed of 5300-5500 r / min, a twist of 230-250 T / m, and a twist tension of 8-10 g. The relative humidity in the twisting area was controlled between 70-75%.

[0057] The weft yarn is twisted using a doubling machine at a spindle speed of 7000-7200 r / min, a twist of 2200 T / m, a Z / S twist direction, and a twist tension of 15-20 g. Since the rayon yarn needs to be protected from moisture and kept dry, the rayon yarn twisting area should ideally be separated from the warp yarn twisting area by a partition, and the lower the relative humidity, the better.

[0058] Step Six: Shaping;

[0059] For the highly twisted weft yarn, because the high twist of 2200T / m is prone to tension and affects product quality, it is necessary to use a high-temperature steaming method to set the yarn, specifically dry steaming, not wet steaming, to stabilize the twist of the yarn, prevent tension, and facilitate unwinding during weaving. The steaming temperature is 85-90 degrees Celsius, the steaming time is 120 minutes, and after steaming, the yarn is left to sit in the steamer for 30 minutes.

[0060] Step 7: Warping; Use the YBGA628 electronic slitting warping machine produced by Jiangyin Youbang Textile for warping operations; the warping speed is 300-350m / min, and the tension is 8-10g. Before starting warping, use a single filament tension tester to check the tension, and adjust the tension of the yarn according to the test results until the preset value is reached; the bobbin has 96 spindles, with about 500 warps per strand. When warping, pay attention to the warping between strands. The winding speed is 50-60m / min, and the winding tension is: 30-35g for the first piece, 28-32g for the middle piece, and 25-28g for the last piece. When the winding is being used for the first piece, the bottom surface of the warp beam should be flattened by using edge paper to prevent defects such as wide and sharp warps, warp warps, and small warps. The relative humidity of the warping area should be controlled between 70-75%.

[0061] Step 8: Threading the heddles and reeds; using heddles 1-32, employing the following sequence: 1, 2, 3, 4, 9, 10, 11, 12, 17, 18, 19, 20, 25, 26, 27, 28, 5, 6, 7, 8, 13, 14, 15, 16, 21, 22, 23, 24, 29, 30, 31, 32, threading 4 heddles and using the forward cut method, 1 heddle / hed, threading reeds: 4 heddles / tooth.

[0062] Step Nine: Weaving.

[0063] The loom uses the Tianma 11-3200 rapier loom manufactured by the Italian company Schmidt, and the jacquard head is the SEJ168H-5376 needle intelligent CNC jacquard device manufactured by Jiangsu Songhe Song Intelligent Technology Co., Ltd. Its weave and pattern are all controlled by computer. The loom speed is 180-200 r / min, with two widths produced. The heddle leveling time is 330°. The warp tension is generally controlled at 28-30g to prevent defects such as warp breaks, strand breaks, and premature warp threads. Warp feed and take-up are automatically adjusted by servo motors, and the electrical control box has an automatic warp correction function to reduce the number of warps that need to be filled or sparse due to stops.

[0064] Because the weft yarn is strongly twisted in both directions, four weft feeders are used during weft yarn application: two for left-hand twist and two for right-hand twist. Weft selection is performed according to a 2Z:2S right-hand ratio, and weft tension is adjusted using devices such as loops, elastic bars, and tension plates. The weft unwinding tension is generally controlled at 12-15g to prevent defects such as weft breakage, weft shrinkage, or weft tightness. The electrical control system has an automatic replacement function in case of weft breakage or sizing, improving equipment efficiency and product quality. The relative humidity in the weaving area should ideally be between 70-75%.

[0065] The specifications of the greige fabric are as follows: greige fabric width is 151cm, average warp density is 104 threads / 10cm, average weft density is 380 threads / 10cm, total warp threads are 15680, the weave is a five-end satin, 32 heddles, numbered 1, 2, 3, 4, 9, 10, 11, 12, 17, 18, 19, 20, 25, 26, 27, 28, 5, 6, 7, 8, 13, 14, 15, 16, 21, 22, 23, 24, 29, 30, 31, 32, using a 4-heddle-4-flying-and-straight-through method, reed number 25.2 teeth / cm, heddle threading: 1 heddle / heddle, reed threading: 4 heddles / teeth.

[0066] The finished specifications of the fabric are as follows: warp density: 112 threads / 10cm, weft density: 400 threads / 10cm, finished width: 140cm, finishing shrinkage rate: 5.3%, dyeing and finishing shrinkage rate: 2.1%, weaving shrinkage rate: 4.2%, and raw fabric shrinkage rate after weaving: 0.5%.

[0067] In this embodiment: the jacquard product Sangbo Satin of the present invention uses mulberry silk as warp and dull rayon as weft, so that the jacquard pattern can better reflect the beauty on the silk fabric, and solves the problem of the single raw material of jacquard products.

The connecting block 911 is rotatably connected to the slider 908.

[0073] In this embodiment: After the drum 11 is installed on the rotating plate 802, the rotating plate 802 is pushed downwards to rotate it. The rotation of the rotating plate 802 causes the connecting seat 909 to rotate synchronously. The rotation of the connecting seat 909 causes the connecting block 911 to move through the telescopic rod 910. The displacement of the connecting block 911 causes the slider 908 to slide within the slide groove 907. At this time, the third spring 912 is compressed. When the slider 908 moves to the middle position of the slide groove 907, the compression force on the third spring 912 is the greatest. After that, the slider 908 continues to move downwards. During the displacement, the third spring 912 resets, thus applying a downward force to the connecting seat 909. The rotation of the connecting seat 909 causes the rotating plate 802 to rotate downwards synchronously, pressing the drum 11 against the rotating roller 7. During this process, the third bevel gear 901 first contacts the conical surface of the rotating roller 7, then slides along the conical surface until the rotating roller 7 contacts the drum 11. When the third bevel gear 901 is displaced, it slides along the rotating rod 805... The outer wall slides, compressing the second spring 904. The horizontal plate 903 slides within the horizontal groove 902. Thus, when the motor 6 drives the rotating roller 7 to rotate, the rotation of the rotating roller 7 drives the third bevel gear 901 to rotate via the helical gear 905. The rotation of the third bevel gear 901 drives the rotating rod 805 to rotate via the horizontal plate 903. The rotation of the rotating rod 805 drives the extrusion column 806 to rotate, and the rotation of the extrusion column 806 drives the drum 11 to rotate synchronously. When the thread is wound on the drum 11, the width of the drum 11... As the thickness gradually increases, displacement occurs between the drum 11 and the rotating roller 7. At this time, the third bevel gear 901 is displaced by the elastic force of the second spring 904, so that the third bevel gear 901 always remains in contact with the helical teeth 905 on the rotating roller 7. This ensures that the drum 11 rotates together with the rotating roller 7, making it easier to wind up the yarn. This prevents the width of the drum 11 from gradually increasing due to the increase in yarn on the drum 11, which would cause the drum 11 to separate from the rotating roller 7 and thus affect the rotation of the drum 11.

[0074] Please refer to this carefully. Figures 1 to 5 The second bevel gear 810 meshes with the first bevel gear 809, and the top end of the rack 803 is provided with a tooth groove, which meshes with the spur gear 807.

[0075] In this embodiment: Rotating the rotating column 812 causes the mounting shaft 811 to rotate, which in turn causes the second bevel gear 810 to rotate, which in turn causes the first bevel gear 809 to rotate, which in turn causes the connecting shaft 808 to rotate, which in turn causes the spur gear 807 to rotate, which in turn causes the rack 803 to move. The two racks 803 move closer to each other, which in turn causes the rotating disk 804 to move, and the displacement of the rotating disk 804 causes the extrusion column 806 to move.

[0076] Please refer to this carefully. Figures 1 to 5 One end of the outer wall of the fixing block 814 is in contact with the inner wall of the fixing groove 813.

[0077] In this embodiment: the fixing block 814 is engaged into the fixing groove 813 by the elastic force of the first spring 815, thereby fixing the rotating column 812.

[0078] Please refer to this carefully. Figures 6 to 9 The outer wall of the rotating rod 805 is in contact with the inner wall of the third bevel gear 901, the inner wall of the transverse groove 902 is in contact with the outer wall of the transverse plate 903, and the third bevel gear 901 meshes with the helical gear 905.

[0079] In this embodiment: when the third bevel gear 901 is displaced, the third bevel gear 901 slides along the outer wall of the rotating rod 805, and the horizontal plate 903 slides in the horizontal groove 902. Thus, when the motor 6 drives the rotating roller 7 to rotate, the rotation of the rotating roller 7 drives the third bevel gear 901 to rotate through the helical tooth 905. The rotation of the third bevel gear 901 drives the rotating rod 805 to rotate through the horizontal plate 903. The rotation of the rotating rod 805 drives the extrusion column 806 to rotate. The rotation of the extrusion column 806 drives the drum 11 to rotate synchronously.

[0080] Please refer to this carefully. Figures 6 to 9 The inner wall of the groove 907 fits against the outer wall of the slider 908.

[0081] In this embodiment: Pushing the rotating plate 802 downward causes the rotating plate 802 to rotate, which in turn causes the connecting seat 909 to rotate synchronously. The rotation of the connecting seat 909 causes the connecting block 911 to move through the telescopic rod 910. The displacement of the connecting block 911 causes the slider 908 to slide within the slide groove 907.
