By holding plain white stock ready to be dyed, it reduces the need to hold too much stock in specific colours that have not been ordered and so may never be used. Female silkmoths lay anything from around 300 – 500 eggs at any one time. The traditional spinning wheel has always, and will always be an integral part of the silk production process. The silk may be fed into the bath through two cylinders, or fixed to a round jig which is immersed in the bath. Although updated industrial processes are now able to spin silk threads much quicker, it simply mimics the functions of the classic spinning wheel. Extracting silk from the cocoon is known as the processing of silk. The process of silk production is known as sericulture. Silk fiber is then spun into silk threads. Raw Thai silk hangs on a rack near Khon Gan. This natural protein or fibroin is secreted from two salivary glands. Bleaching is the process when silk need to treat with oxides. Because the fibres area unit need to combine and force on to the reel, twist will insert to carry the filaments along. Here is a brief description of silk production. Silk materials need only a few finishes as a result of they need natural lustre, softness and drapability. Silk has nice affinity for the dyes. At this stage the worm desires special care bamboo trays with straw mats area unit provided for them. Should a piece of silk require a special pattern or design, it will need to be printed after pre-treatment. On average, 36,000 worms consume 1 ton of mulberry leaf over their lifetime. In general, the life cycle of the silkworm has four stages - starting with the egg stage and ending with becoming moths. The larvae feed on mulberry leaves. Advances in technology mean that manufacturers instead opt for using various dyes such as acid dyes or reactive dyes. 1. Gather all information on process steps from start to finish. Each thread is then carefully reeled from the cocoon in individual long threads, which are then wound on a reel. Silkworm is an insect that makes silk. It comes from the cocoon of the silk worm and requires a great deal of handling and processing, which makes it one of the most expensive fibers also. Silk has set the standard in luxury fabrics for several millennia. The threads will be woven at right angles to each other, and the two different angles are called a warp and a weft. Silk worm begins life as an egg, and then it becomes a silk worm, pupa and, finally, a moth. Here 3 to 10 strands area unit sometimes reeled at a time to supply the specified diameter of raw silk thread. The warp will run up and down the fabric, while the weft runs across it. The method of unreeling the filament from the cocoon is reeling. Step 2: … Similarly, the production of silk thread has different steps, which initiates with the selection of the silk threads and finishes with dying the yarn. Different stencilling techniques include: Using masking tape … The health benefits of silk: The secret to a youthful, glowing complexion. However, silk production remains one of the cleanest textile industries; mulberry trees do not require fertilizers or pesticides, which means it’s possible to harvest cultivated silk without introducing any toxic chemicals into the environment. .hide-if-no-js { According to Confucian text, the discovery of silk production dates to about 2700 BC, although archaeological records point to silk cultivation as early as the Yangshao period (5000–3000 BC).
