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 (picking), 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 fixing 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
