The Processing Of Silk Cocoon Into Silk Thread For Making Silk Chengdu Here is a step by step guide to the fascinating process in which silk is produced…. 1. sericulture. this is the term used to describe the process of gathering the silkworms and harvesting the cocoon to collect the materials. female silkmoths lay anything from around 300 – 500 eggs at any one time. these eggs eventually hatch to form. Posted by manito. 30 nov. silk is a luxurious and highly sought after fabric with a fascinating journey from cocoon to fabric. the process begins with sericulture, the raising of silkworms to produce silk. the most commonly used silkworm is the larvae of the bombyx mori. this larvae spin a cocoon using silk fibers produced from its salivary glands.
Silk Cocoon Processing Heating and spinning of cocoons. when processing silk, one of the essential steps involves heating and spinning silkworm cocoons to extract the valuable silk fibers efficiently. the process of heating and spinning cocoons is vital in silk making for obtaining high quality silk threads. here are some key points to understand this step better:. Each of the cocoons is made out of a single long silk fiber, that the larvae produce using their special silk glands. a cocoon is about the size of a cotton ball, but the silk fiber that makes up the cocoon can measure up to 1.6 kilometers in length. the color of a cocoon can range from white to yellow, depending on the type of silkworm and its. Each silkworm now doubles itself up on its back, and by contracting secretes, from an opening under its mouth, a steady stream of liquid silk, coated with sericin, which hardens on exposure to air.
