We got to see the four stages of finishing that cloth merchants fabrics such as Holland & Sherry, Dormieul, Scabal, H. Lesser & Sons, etc..
The four stages are scouring, cropping, setting and pressing.
The scouring can be done to suit the type and quality of the textile. A simple British wool rug may just get a rope scouting and a drying and that will be enough.
But for a linen or a cashmere fabric then a much softer jet scouring will be used.
Let me know what you think and comment below.
