There are many raw materials for yarn-making. Among them are cotton, silk, wool, oil, and plastic bottles. Cotton and plastic (polyester), however, are the most popular choices for yarn makers. Between 70 and 80 per cent of garments at department stores today are made from cotton or polyester fabrics.
Conventionally, textile making has functioned in the linear economy whereby new resources are used for manufacturing and waste from the manufacturing is disposed of. But today, the circular economy concept has taken a foothold in the textile industry. Based on this, resources in the system are used and then recycled with a minimal intake of new raw materials.
