The design and the decorations of Chinese rugs are very neat and defined. They are generally reproductions of great old persian rugs. Silk is inlaid around the edges of flowers to add definition. Chinese manufacturers have the best quality control and the wool they use is very effectively washed.
They use colors at a high professional level and color fading is almost absent.
In China there’s also a tradition of rugs made of silk.
Silken rugs are more expensive and they require much more care to last in time. Since silk is a very thin yarn the knot density is very high, allowing very detailed patterns.
