Description

Technical Field

[0001] The invention relates to the technical field of fabric weaving, in particular to a jacquard fabric production process. Background Art

[0002] Qiwan refers to the fine white silk produced in the ancient Qi region. Its name derives from the delicate, glossy white silk "wan" produced in Linzi. Today, it generally refers to precious silk fabrics. Modern Qiwan jacquard craftsmanship, while inheriting tradition, continues to integrate new technologies and design concepts, achieving significant developments in raw materials, processes, equipment, and applications. Sangbo satin, a type of Qiwan silk jacquard fabric, refers to a weaving method in which warp and weft threads are regularly placed or interwoven on the surface of the silk fabric, creating a pattern or design. Sangbo satin products feature a distinct satin texture, an antique charm, and a variety of patterns, creating a truly elegant look. Thicker than georgette, it is relatively soft, opaque, and has a low depreciation rate after washing, is resistant to fading, and has vibrant colors. These products are commonly used in home textiles (such as bedding and sofa fabrics) and high-end fashion.

[0003] Sangbo satin features a wide variety of patterns and a complex manufacturing process. The production of Qiwan jacquard satin requires over a dozen major processing steps, including raw material inspection (selection), soaking, drying, winding, doubling, twisting, shaping (steaming), warping, reeding, weaving, inspection, and smelting. However, the production of this type of all-silk jacquard fabric suffers from the monotony of raw materials, resulting in a lack of three-dimensionality and a flat pattern.

[0004] Furthermore, because the uniformity of the thickness of the warp and weft yarns in jacquard fabrics directly affects the three-dimensional effect 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 filaments is synchronously controlled, eliminating defects such as knots and uneven tension in the original yarns and ensuring a more uniform density of the combined strands. In jacquard weaving, uniform density is crucial for ensuring the clarity of the jacquard pattern. Reducing manual intervention and operations based solely on experience in the doubling process and providing standardized or automated operation capabilities for the equipment can significantly improve production efficiency, reduce costs, optimize product quality, and enhance operational safety. However, existing silk doubling machines still require manual and empirical operation for winding, clamping, catching, and unwinding, resulting in limited efficiency and quality assurance, which further impacts the color reproduction of the jacquard fabric.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and should not be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected, detachably connected, or connected in one piece; they can be mechanically connected or electrically connected; they can be directly connected, or indirectly connected through an intermediate medium, or they can be internal connections between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0024] In an embodiment of the present invention, a jacquard fabric production process includes the following steps: Step 1: Raw material selection; choose 2 / 20 / 22D mulberry silk as the warp, 1 / 75D matte rayon as the weft, and five-piece satin on both sides as the basic structure of the fabric.

[0025] Step 2: Soak the silk; the bath ratio of the warp is 1:5, the mass ratio of the added silk soaking agent is auxiliary agent: silk = 7.5:90, the water temperature is 40-42 degrees Celsius, and the soaking time is 45 minutes; the weft uses 1 / 75D matte rayon and does not need to be soaked.

[0026] The foaming agent is EKL-300A high-speed additive produced by Hangzhou Xinyinglun Technology Co., Ltd. This additive has the following characteristics: 1) Make the raw silk have excellent smoothness, softness, antistatic and mildew resistance; 2) Imparting excellent strength to raw silk, which can improve elongation and cohesion; 3) The color is evenly distributed during soaking and it is easy to scour thoroughly during refining.

[0027] Step 3: Winding; Use the GD001-145 winding machine produced by Hangzhou Textile Machinery to wind the warp: the winding speed is 130-140m / min, the winding tension is 5-15g, and the relative humidity in the winding area is controlled between 60-65%; the weft is made of 1 / 75D matte rayon and does not need to be wound.

[0028] Step 4: Winding; use the improved winding machine to wind the warp yarns: the winding speed is 350-4000m / min, the winding tension is 6-8g, of which the single yarn tension is 3g, and the relative humidity of the warp winding area is controlled between 60-65%.

[0029] The improved winding machine is used to draw the weft yarn: the winding speed is 350-400m / min, and the winding tension is 10-15g; because the strength of the rayon raw material decreases significantly after absorbing moisture, and it is easy to break and produce tight wefts, so the rayon winding area must be moisture-proof and dry, and the lower the relative humidity, the better.

[0030] Step 5: twisting the silk; The R362 / S two-for-one twister produced by Italy's Latti Company was selected to twist the warp yarns at a spindle speed of 5300-5500 r / min, a twist of 230-250 T / m, and a twisting tension of 8-10 g. The relative humidity in the twisting area was controlled between 70-75%.

[0031] 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 twisting tension of 15-20 g. Because rayon yarn needs to be moisture-proof and dry, the rayon twisting area is best separated from the warp twisting area by a partition, and the lower the relative humidity, the better.

[0032] Step 6: Finalize the shape; Because the reinforced twist weft yarn, with a twist of 2200 T / m, is prone to tension and affects product quality, it is necessary to heat-steam the matte rayon yarn. Dry steaming is recommended, not wet steaming, to stabilize the twist and prevent tension, ensuring smooth unwinding during weaving. The steaming temperature is 85-90 degrees Celsius for 120 minutes, followed by a 30-minute simmering.

[0033] Step 7: Warping; select the YBGA628 electronic slitting warping machine produced by Jiangyin Youbang Textile for warping; the warping speed is 300-350m / min, the tension is 8-10g, and the tension should be tested with a single-filament tension tester before warping. According to the test results, the tension of the silk thread is adjusted until it reaches the preset value; the creel has 96 spindles, and each twist is about 500. When warping, pay attention to the pressure between twists. The reel speed is 50-60m / min, and the reel tension is: 30-35g for the first piece, 28-32g for the middle piece, and 25-28g for the last piece. When reeling, the bottom surface of the warp beam should be flattened by lining paper to prevent defects such as wide and sharp willows, warp willows, and prying. The relative humidity in the warping area is controlled between 70-75%.

[0034] Step 8: Drawing in the healds and reed; use 1-32 rows of healds, adopting 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, drawing in 4 and flying 4, straight out method, 1 heald / reed, drawing in the reed: 4 healds / tooth.

[0035] Step 9: Weaving.

[0036] The loom features a Tianma 11-3200 rapier loom manufactured by Schmidt, Italy, and a SEJ168H-5376-needle intelligent CNC jacquard unit manufactured by Jiangsu Songhesong Intelligent Technology Co., Ltd. The weave and pattern are all computer-controlled. The loom operates at a speed of 180-200 r / min, with two-width production and a 330° flattening time. The tension is typically controlled at 28-30g, ensuring no defects such as broken ends, broken strands, or premature warps. Warp let-off and take-up are automatically adjusted by servo motors, and the electronic control box features an automatic gear-spacing function to minimize the risk of over- or under-spacing due to stops.

[0037] Because the weft yarn is strongly twisted left and right, four weft feeders are used during weft production: two for left-twist and two for right-twist, selecting the weft in a 2Z:2S ratio. Weft tension is adjusted using loops, elastic rods, and tension plates. The weft unwinding tension is typically controlled between 12-15g to prevent defects such as weft breakage, weft shrinkage, and tight wefts. The electronic control system features an automatic replacement function for weft breakage or weft stretching, improving equipment efficiency and product quality. The relative humidity in the weaving area should ideally be between 70-75%.

[0038] The grey fabric specifications of the fabric are as follows: the grey fabric width is 151 cm, the average warp density of the grey fabric is 104 threads / 10 cm, the weft density of the grey fabric is 380 threads / 10 cm, the total warp number is 15680 threads, the structure is five-piece satin on both sides, 32 rows of heddles, 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, the method of drawing in 4 and flying 4, and drawing in along the way, the reed number is 25.2 teeth / cm, the drawing in of heddles is 1 thread / heddle, and the drawing in of heddles is 4 / tooth.

[0039] The finished product specifications of the fabric are: warp density: 112 threads / 10cm, weft density: 400 threads / 10cm, finished product width: 140cm, smelting shrinkage: 5.3%, dyeing and finishing shrinkage: 2.1%, weaving shrinkage: 4.2%, and grey silk off-machine expansion rate: 0.5%.

[0040] In this embodiment, the jacquard product of the present invention, mulberry silk, is made of warp and matte rayon is made of weft, so that the jacquard pattern on the silk fabric can better reflect the beauty, thus solving the problem of single raw material of jacquard products.

Then the motor 6 is started, and the motor 6 drives the rotating roller 7 to rotate. The reel 11 rotates together with the rotating roller 7. The silk thread is wound on the reel 11, and the silk thread moves along the guide groove 10, so that the silk thread is evenly wound on the reel 11.

[0043] Please refer to Figures 1 to 5 The mounting mechanism 8 includes a mounting frame 801, which is fixedly connected to the top of the machine base 1. The top of the mounting frame 801 is rotatably connected to a rotating plate 802. The two sides of the rotating plate 802 are symmetrically slidably connected to gear rods 803.

[0044] In this embodiment: when installing the reel 11, the reel 11 is placed between the two extrusion columns 806, and the fixed block 814 is pushed away from the rotating column 812 to displace it, causing the first spring 815 to be squeezed, and the rotating column 812 is rotated. The rotation of the rotating column 812 drives the installation shaft 811 to rotate, and the rotation of the installation shaft 811 drives the second bevel gear 810 to rotate. The rotation of the second bevel gear 810 drives the first bevel gear 809 to rotate. The rotation of the first bevel gear 809 drives the connecting shaft 808 to rotate. The rotation of the connecting shaft 808 drives the spur gear 807 to rotate. The rotation of the spur gear 807 drives the gear rod 803 to displace. The two gear rods 803 approach each other for displacement, driving the rotating disk 804 to displace. The displacement of the rotating disk 804 drives the extrusion column 806 to displace. The two extrusion columns 806 move and are inserted into the two ends of the reel 11 to clamp the reel 11. After completion, the fixing block 814 is released. 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 and thus fixing the position of the reel 11. This facilitates the rapid installation and removal of the reel 11 and facilitates subsequent processing operations. The improved equipment operation process is easy to standardize, and even skilled operators can properly perform the above steps.

[0045] Please refer to Figures 6 to 9 The rotating mechanism 9 includes a third bevel gear 901, which is slidably connected to the outer wall of the rotating rod 805. A transverse groove 902 is provided on the inner wall of the third bevel gear 901. The outer wall of the rotating rod 805 is symmetrically fixed with a transverse plate 903. A second spring 904 is connected between the third bevel gear 901 and the rotating disk 804. Conical surfaces are symmetrically provided at both ends of the rotating roller 7. The outer wall of the conical surface is fixedly connected with a helical tooth 905. The top of the base 1 is fixedly connected to both sides of the rotating plate 802.

The connecting seat 909 rotates and drives the connecting block 911 to move through the telescopic rod 910. The displacement of the connecting block 911 drives the slider 908 to slide in the slide groove 907. At this time, the third spring 912 is squeezed. When the slider 908 moves to the middle position of the slide groove 907, the squeezing force on the third spring 912 is the largest, and then the slider 908 continues to move downward. When the third bevel gear 901 is displaced, the third spring 912 performs a reset operation, thereby giving the connecting seat 909 a force to rotate downward. The connecting seat 909 rotates and drives the rotating plate 802 to rotate downward synchronously. The rotating plate 802 rotates so that the reel 11 is pressed against the rotating roller 7. During this process, the third bevel gear 901 first contacts the conical surface of the rotating roller 7, and then the third bevel gear 901 slides along the conical surface until the rotating roller 7 contacts the reel 11. When the third bevel gear 901 is displaced, the third bevel gear 901 moves along the rotating rod 805. The outer wall slides, squeezing the second spring 904, and the horizontal plate 903 slides in the horizontal groove 902.
