Each silkworm produces just one single strand of silk, which measures about 100 metres long and is held together by a type of natural gum, called sericin. STEPS: Sericulture– Cultivation of the silkworm cocoon for their filaments is known as sericulture. Silk worm begins life as an egg, and then it becomes a silk worm, pupa and, finally, a moth. Silk production process. Your email address will not be published. While there are now a huge variety of different types of insects used to produce silk, the most commonly used species is the larvae of ‘Bombyx mori’ – (the caterpillar of the domestic silkmoth).

Printing on silk varies by any technique like roller printing, Screen printing or block printing. 1. Similarly, the production of silk thread has different steps, which initiates with the selection of the silk threads and finishes with dying the yarn. Over the years we’ve learnt a lot about the process and we’ve even developed our own blends, such as silk-cotton which is ideal for nightwear.

Here 3 to 10 strands area unit sometimes reeled at a time to supply the specified diameter of raw silk thread. During this time, removing silkworm eggs or cocoons from China was punishable by death. At constant time it conjointly secretes a viscous quite fluid referred to as ‘sericin’ that passes through constant gap.  =  The production of silk generally involves two processes: The silkworm caterpillar builds its cocoon by producing and surrounding itself with a long, The process of spinning essentially unwinds the dyed fibres on to a bobbin, so that they lay flat ready for the weaving process. The cocoons are placed into boiling water in order to soften and dissolve the gum that is holding the cocoon together. Your email address will not be published. Bleaching is the process when silk need to treat with oxides. The process of cultivating the silkworm for the production of raw silk is called as sericulture. Silkworms hatch out of the eggs and are fed with mulberry leave.

When the silk threads have been washed and degummed, they will be bleached and dried before the dyeing process commences. This natural protein or fibroin is secreted from two salivary glands. The threads will be soaked together in bundles, inside a pot of hot indigo leaves and water. The threads will be woven at right angles to each other, and the two different angles are called a warp and a weft. However, these traditional dyeing methods have almost become extinct in the commercial manufacturing of silk. The process of silk production is known as sericulture. Step 1: Raising silkworms & harvesting cocoons. Despite advances in production method technologies, silk production still very much remains a labour intensive process, and a lot of hard work is involved. Here is an outline of the different steps involved in the production of mulberry silk and the people employed at each step. Advances in technology mean that manufacturers instead opt for using various dyes such as acid dyes or reactive dyes. The extraction of raw silk starts from the cultivation of silkworms. Once the silkworms have spun their cocoon, they will eventually enclose themselves inside it and then it’s time to extract the silk threads. Each thread is then carefully reeled from the cocoon in individual long threads, which are then wound on a reel. The fibroin gets hardened once exposed to air. These area unit full-grown by the agriculturists. Silk has set the standard in luxury fabrics for several millennia.

In the third month of the lunar calendar which was called “silkworm month” silkworms breeding process started. Once the silkworms have spun their cocoon, they will eventually enclose themselves inside it and then it’s time to extract the silk threads.

It’s not sometimes removed till when the fabric is woven  as a result of is warp filler that protects the yarns from mechanical injury throughout weaving.
