The more number of weft yarn reeled together, the heavier the silk fabric becomes. More ply means more thickness and less smoothness. Th… Step 6: Weaving. Most of the cocoons are used in silk making but some of them leave the cocoon as butterflies by secreting liquid onto the silk threads to dissolve them, so they can emerge. The introduction of silk made a significant impact on these societies. Legend has it that a Chinese princess was sipping tea in her garden when a cocoon fell into her cup, and the hot tea loosened the long strand of silk. Log in. Weaving is the process in which the final piece of silk comes together. Generally, weaving involves interlacing two sets of threads so that they lock around each other and create a strong, uniform piece of fabric. Silk has set the standard in luxury fabrics for several millennia. First, cocoons are stored by color, size, shape and texture. Crepe de Chine is made by twisting some fibers clockwise and others counterclockwise before weaving, producing a fabric with a pebbly texture and the fabric is lightweight and does not ravel easily like other silks. Join now. Although some silkworms are allowed to become moths to propagate the species, most of them are harvested in this stage to be used in silk production. A fast weaver can weave up to a maximum of 9-10 yards a day for a simple plain weave. Silk Production Process in Ancient China. History of Silk. silkworms on mulberry leaves. By 300 AD, women in central and western Asia were using Chinese silk thread with most woven silk fabrics. Spin silk thread by hand on wooden or plastic tubes to be prepared for warp or weft. The origins of silk date back to Ancient China. Silkworm is a stage of the silk moth’s life cycle. Degumming is generally carried out by following treatments: (a) Extraction with water: In this process, silk thread is treated in hot water (100-130°C) for 30 minutes to 4 hours, which can cause degumming of sericin. Crinkly fabrics are made with crepe, while sheer cloth is made with single thread. This is where cocoons are turned into silk threads through a four-step process. © Thongseng Ltd Partnership All rights reserved. start pupating in their cocoons, these are. A cocoon can extract about 1000 meters of cocoon silk, and some cocoons and silk will be merged into raw silk. Dye silk thread in a dye bath. Then the sericin or silk gum holding the cocoon's filaments together is softened by alternating hot and cold immersions. Spun silk is comprised of broken filaments that have been processed into a yarn. Silkworms increase in length to more than 5 cms within 20-24 days of their feeding time and shed their skin several times in the process. On average, 36,000 worms consume 1 ton of mulberry leaf over their lifetime. After our tour of Suzhou's Grand Canal and one of the smaller side canals, we boarded the tour bus and headed off to a silk factory for a demonstration on the silk-making process. Silkworms are actually domesticated insects, incapable of flight, mate quickly after emerging from their chrysalis, and die a day or so after laying eggs. Designboom has a fascinating pictorial of the traditional silk making process of the craftspeople in a small village in north-east Tailand. Nevertheless, it is this manual process that gives Thai silk a lustrous sheen and slightly uneven texture that distinguishes it from the sleek machine-woven fabric. It is carried out to impart the lustrous and softness on silk. Silk yarns must be washed and degummed by immersing the skeins in large tubs of hot water. It simply means the number of threads used for the weft when weaving silk fabric. Ask your question. For this, it is need to be exposed to warmth. PROCESSING. Here, we will show you some silks. Dyes are prepared in a dye bath. China silk, also called “plain silk,” is the least expensive of the silks, and is lightweight and shiny. After the warp and weft are prepared, the loom is set and the weaver begins by pushing down the harness to separate the two sets of warp threads, leaving space to shoot the The protein fiber of silk is composed mainly of fibroin and is produced by silkworms larvae to form cocoons. Answered State the process of making silk 2 Using spinning wheels, dyed silk skeins are then unwound by hands onto wooden or plastic bobbins to be prepared for warp or weft in the weaving process. The filaments from several cocoons are then reeled together on a wooden spindle into a uniform strand of raw silk. Farmers deliver the cocoons to filatures (special factories), and here cocoons are turned into silk threads through a four-step process. Silk fibers are combined into silk thread.The thread can then be twisted into silk yarn or woven into silk cloth (fabric). You can also collect the cocoons of wild silkworms, but this is less common. The cruel process of making silk Silk is the fibre that silkworms weave to make their cocoons – outer casings that protect them during the pupal stage. upendrachaudhary777 upendrachaudhary777 7 days ago Science Secondary School +5 pts. The cultivation of domesticated silkworms is, by nature, an inherently sustainable process, but there are ethical issues; the commercial production of silk involves destroying the silkworm before it emerges from its cocoon. Therefore, to obtain silk, the Koya is put into the boiling water, so that the silkworm which is inside it, died there and segregates thread from it. The process of making Silk. Weaving silk by hand loom is a rather time consuming and require special skill. The dyed yarns are then hung in the shade to dry before they can be spun onto bobbins. The threads will be woven at right angles to each other, and the two different angles are called a warp and a weft. Only the filament produced by Bombyx mori, the mulberry silk moth and a few others in the same genus, is used by the commercial silk industry. In the reeling process, a special wooden device is used to locate the end of the filament, after which it must be carefully unwound, a process that not only requires hard work over a boiling pot, but also practiced skill to keep the threads unbroken. However, this fabric tears easily. The degumming process leaves silk lustrous and semitransparent, with a smooth surface that does not readily retain soil. After they have moulted several times, they spin a cocoon. The final scene, on the left, shows silk being woven. It is removed by washing it with soap and boiling water. Step 1: Raising silkworms & harvesting cocoons. 2-ply, 4-ply, 6-ply is often used to indicate the weight of Thai silk fabric. Step 2: Thread extraction. Different methods of twisting are used to get the various types of silk yarn: crepe, organzine, singles, etc. The Process Of Making Silk - May 21, 2018 - First step: Silk Reeling The silk is extracted from the cocoon and becomes the raw material for the fabric. The people living in the region were the inventors of silk fabric, and no other culture discovered this process independently. The silk solidifies upon contact with air. In about 10-14 days each of the eggs hatches and produces a larva which is also known as a caterpillar. A cocoon is a protective case or shell that the silkworm spins around itself. Arun Yarns deal with manufacturing of 100% Mulberry Pure Silk Yarn. Related Products Weavers open the warp by stepping on pedals, their hands and feet must work in perfect unison to enable the warp and weft yarns to interlace correctly. Step1: Separation of the silk fibre from the cocoon. Step 3: Dyeing. Each Thai silk cocoon can give about 700 yards long of filament. Larvae are fed mulberry leaves.

Silk is a beautifully lustrous fabric made from an animal fiber with the same name. It was believed that an ancient Chinese princess was the first to discover the process for manufacturing silk fabric from the filament fiber produced by silkworms. Second, soften the silk gum holding the cocoon’s filaments together by alternating hot and cold immersions. The third scene shows the process of spooling. long fibres to be extracted and fed into the. Once the worms. The process of making silk is called sericulture, and it involves harvesting silkworms for the material. Silk Making Process Step 1: Raising silkworms and harvesting cocoons.
