His research team collected data and interviewed silkworm raisers and a silk textile handicraft groups in Phu Wiang district and learned about the properties of the cocoons. He said silkworm cocoons were used because silkworms are raised and farmed in many areas of Khon Kaen, which has a reputation for quality silk clothing. The vests are 14-20 millimetres thick, weigh 2.5-4 kilogrammes, and cost only one-third the price of conventional bullet proof vests, he said. The armour, made from silkworm cocoons mixed with a special resin and then hydraulically compressed, is durable and lightweight, said Mr Panomkorn, a chemical engineering lecturer.
