Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric weaving, and particularly relates to a double palace silk fabric processing technology. BACKGROUND

[0002] Double palace silk is made from double palace cocoons spun by two silkworms. The double palace silk is not as uniform as the single cocoon silk, and has irregular points and nodes. This is because the two silkworms do not have enough space when spinning silk, and if they always spin in one direction, they are easy to stack together, forming a point, and the long point forms a node. Under normal conditions, one silkworm forms one cocoon, forming a normal cocoon. When two silkworms form one cocoon, a double palace cocoon is obtained, and the silk spun from the double palace cocoon is called double palace silk. Only 3-5 of every 100 cocoons are double palace cocoons, and manual screening is required, which is very high in raw material cost.

[0003] Because the single silk of the double palace cocoon is much thicker than the single silk of the normal cocoon, the double palace silk produced is also thicker than the silk of the normal cocoon. The double palace silk is characterized by thick silk and many nodes, and the surface presents obvious irregular nodules. The fabric made of the double palace silk is double palace silk. The double palace silk is tough and thick, has a unique style, and has a restrained and low-key luster, and belongs to high-grade silk fabric. In the traditional process, the production of the double palace silk needs to go through more than ten main processing procedures such as raw material selection and inspection (picky), soaking, silk airing, silk winding, silk doubling, silk selection, setting (silk steaming), warping, head picking and reed closing, weaving, inspection, and finishing, and the preparation process is relatively complicated.

[0004] In addition, the double palace silk raw material used in the present application has a strand of about 5 times the factory silk and is uneven in thickness. Sometimes the thin part is as thick as the factory silk, and the thick part is 5-10 times thicker than the factory silk. Therefore, the double palace silk is more difficult to process than the factory silk, and the process requirement is also higher. The product added value of the double palace silk is about twice that of the normal factory silk fabric, which can bring good economic benefits to the enterprise. The processing difficulty of the double palace silk mainly lies in the following aspects.

[0005] (1) During the raw material picking, special attention should be paid to large thick strands, large hard corners, yellow and black cocoon spots, and smoke willow defects. Such defects should be removed in this picking process.

[0006] (2) During the soaking process, because the double palace silk is thicker and has a large cocoon skin, in order to ensure the soaking quality, the soaking water temperature and soaking time of the double palace silk should be longer than those of the factory silk raw material.

[0007] (3) During the silk winding process, the winding tension should be appropriately increased and controlled to ensure the formation of the bobbin and the winding tension.

[0008] (4) During the silk doubling process, because the double palace silk has many hard nodules, large ear type guide rollers should be used to reduce the number of broken ends and tight weft.

[0009] (5) In the twisting process, the spindle speed should not be too high, the tension should be relatively large, and the guide wire eye should be large.

[0010] ⑹ In the weaving process, because the double-core yarn is uneven in thickness and has many large knots, in order to reduce weft breakage and shrinkage and improve the silk surface effect, the more weft feeders the better, no less than 4. The steel mesh of the weft feeder should be replaced with loops, the tension clamp should be replaced with elastic bars, the scissor head should be tightly clamped, and timely inspection should be carried out.

[0011] (7) The relative humidity of each processing step in the workshop should be properly adjusted and controlled to prevent defects such as broken ends, broken weft threads, and small gaps.

[0012] Because each process involves certain technical difficulties and is interconnected, only by properly solving the technical problems encountered in the production of double-silk products can the smooth progress of production be guaranteed. Especially during the winding process, to avoid defects inherent in double-silk such as uneven thread thickness, numerous knots, and tangling caused by two silkworms spinning the same thread, it is necessary to reduce the risk of weft breakage during weaving through the winding process. It is also necessary to control the thread tension during winding, and the wound thread must achieve a soft and smooth feel to improve the flatness and durability of the final silk. The winding process requires tensioning the thread using tension wheels. However, when positioning the thread on the spool onto the drum, the thread needs to be wound sequentially onto the tension wheel and support wheel. Operators also need to flexibly adjust the thread tension according to the actual conditions of different batches of double-silk. When fixing one end of the thread to the drum, additional tape is needed for fixation; improper fixation can lead to unwinding.

[0013] In view of this, in order to overcome the technical problems in the prior art, a double-layer silk fabric processing technology is provided. Summary of the Invention

The embodiments of the present application will be described below according to the overall structure of the present application.

[0049] Please refer to Figures 1 to 9 In the embodiments of the present application, a double palace silk fabric processing process comprises the following steps:

[0050] Step one: raw material selection; select 2 / 20 / 22D mulberry silk (factory silk) as warp, select 2 / 100 / 120D double palace silk as weft.

[0051] Step two: soaking; the bath ratio of warp is 1:5, the mass ratio of auxiliary and warp is 7.5:90, the water temperature is 40-42 degrees Celsius, the soaking time is 45 minutes; the bath ratio of weft is 1:6, the mass ratio of auxiliary and weft is 8:90; the mass ratio of smoothing agent and weft is 0.1:90; the mass ratio of acetic acid and weft is 0.15:90; the water temperature is 48-50 degrees Celsius, the soaking time is 4-6 hours. The soaking auxiliary selects EKL-300A high-speed auxiliary produced by Hangzhou Xinying Science and Technology Co., Ltd., which has the following characteristics: 1) excellent smoothness, excellent softness, good antistatic property and mildew resistance; 2) gives raw silk excellent strength and cohesion; 3) uniform coloring during soaking, easy to completely refine during refining.

[0052] Step three: winding; use a winding machine, wherein: the warp winding line speed is 130-140 m / min, the winding tension is 5-15 g, the weft winding line speed is 120-130 m / min, the winding tension is 20-50 g, and the relative humidity of the winding area is controlled between 70-75%.

[0053] Step four: doubling; select GD102 doubling machine produced by Hangzhou Tianxin Spinning Machine Co., Ltd., the warp doubling line speed is 350-4000 m / min, the doubling tension is 6-8 g (single filament tension is about 3 g), the weft doubling line speed is 300-350 m / min, the doubling tension is 35-40 g (single filament tension is about 20 g), and the relative humidity of the doubling area is controlled between 70-75%.

[0054] Step five: twisting; select R362 / S doubling and twisting machine produced by Italy Latte Company, the warp spindle speed is 5300-5500 r / min, the twist is 230-250 T / m, the twisting tension is 8-10 g; the weft spindle speed is 4500-4700 r / min, the twist is 230-250 T / m, the twisting tension is 40-50 g, and the relative humidity of the twisting area is controlled between 70-75%.

[0055] Step Six: Warping; Use the YBGA628 electronic slitting warping machine manufactured by Jiangyin Youbang Textile. The warping speed is 300-350m / min, the tension is 8-10g, and the relative humidity of the warping area is controlled between 75-80%. Before starting warping, use a monofilament tension tester to check the tension and adjust it according to the test results. The bobbin has 96 spindles, with about 500 warps per strand. During warping, pay attention to the pressure between strands. The winding speed is 50-60m / min. The winding tension is: 30-35g for the first piece, 28-32g for the middle piece, and 25-28g for the last piece. When winding the warp, use edge paper to flatten the bottom surface of the warp beam to prevent defects such as wide and sharp warps, warp warps, and small warp pieces.

[0056] Step 7: Threading the heddles and reeds; using heddles from pages 1 to 8, follow the 1, 2, 3, 4, 5, 6, 7, 8 sequence, 1 heddle per heddle, threading 2 heddles per tooth.

[0057] Step 8: Weaving; Use the Tianma 11-3200 rapier loom manufactured by Italian company Schmidt, with a loom speed of 220-240 r / min, a heddle leveling time of 330° (heddle leveling time refers to the moment when the heddle frames move to a level state during the weaving process, expressed as the position angle of the loom spindle), and a relative humidity of 75-80% in the weaving area to produce the fabric.

[0058] The tension on the machine should be controlled at 28-30g to avoid defects such as broken ends, broken strands, abrasions, sudden warp, and small gaps. The feeding and winding are automatically adjusted by servo motors. At the same time, the electrical control box has an automatic gap-filling function to reduce the number of close or sparse gaps caused by stopping.

[0059] Because the thickness of the double-layered yarns is uneven and varies considerably, in order to reduce the resulting inconsistencies in the thickness of the silk surface, at least four weft feeders are used during the weft yarn application process. The weft tension is adjusted using devices such as loops, elastic bars, and tension plates. The weft unwinding tension is generally controlled at 25-30g to prevent defects such as weft breakage, weft shrinkage, and weft tearing. The electrical control box system has an automatic replacement function in case of weft breakage or tearing, which improves equipment efficiency and product quality.
