An oriental rug like this one This one They are 2 examples of Islamabad from Pakistan. This type of ierntal rug is very common in my country. The Pakistani sellers say this rug is made of wool and silk, where silk is the light part of the carpet. In my opinion it is a fraud! In my opinion the light part of the rug is cotton. I have difficulty washing these rugs. After washing, the light part is not soft and and the aesthetic result is not the best. I usually wash these rugs with a woolsafe prespray (Prochem Prespray Gold) and rinse with an acid rinse. Where is the error?
