through several guides and wound onto reels. This process of throwing produces various yarns depending on the amount and direction of the twisting. The threads may be plied to form yarn (short staple lengths are spun; see silk noil). After drying, the raw silk is packed according to quality. Sustainable Silk Peace silk The most popular substitute for traditional silk is peace silk, also known as ahimsa silk. The primary factor that makes this form of silk more ethical is that moths are permitted to emerge from their cocoons and fly away before they are properly boiled. It denotes that no moth is ever cooked alive during manufacture. Even though peace silk is superior to regular silk, there is a big disadvantage to be aware of. Domesticated silkworms used to make silk have undergone thousands of years of selective breeding, yet they are not "manufactured" to emerge from their cocoons. They are unable to defend themselves against predators since they cannot fly or see clearly. They typically die very rapidly after emerging from their cocoons as a result. Wild silk The cocoons of Tussar silkworms, which are found in open woodlands, are used to produce wild silk, also known as Tussar silk. Compared to conventional silk, their cocoons are typically picked after the moths have emerged, making it a more ethical option. Because wild silkworms consume a variety of plants, their fabric is less uniform but more robust. The fabric is made with fewer chemicals as well. The larvae are still inside the cocoons when they are harvested by certain enterprises that employ "wild silk," though. Stages of production The stages of production are as follows: The female silkmoth lays 300 to 500 eggs. The silkmoth eggs hatch to form larvae or caterpillars, known as silkworms. The larvae feed on mulberry leaves. Having grown and moulted several times, the silkworm extrudes a silk fibre and forms a net to hold itself. It swings itself from side to side in a figure '8', distributing the saliva that will form silk. The silk solidifies when it contacts the air. The silkworm spins approximately one mile of filament and completely encloses itself in a cocoon in about two or three days. The amount of usable quality silk in each cocoon is small. As a result, about 2,500 silkworms are required to produce a pound of raw silk. The intact cocoons are boiled, killing
