What is wrong with silk?
Silk is produced by silkworms. Silk is a monofilament that can be reeled off as one continuous thread if the cocoon is not damaged by the emerging moth. Silk can also be produced by spinning the threads from the empty cocoons after the moths have emerged, but this produces a coarser grade of silk. To get the longer silk threads, cocoons are boiled with the living moth larvae inside. When silkworms are boiled alive they show signs of pain by twisting and turning while recoiling. Many vegans do not wear silk because it is a fabric produced by living beings.
