How is the carpet embossed like a relief?

The carpet surface pattern is three-dimensional, and the embossing is very strong. Most people don't know what is going on, the weaving process is different, or what secret is there. In fact, such an effect is only one of the carpet production processes, also known as "cut flowers", "slices", "slots". The trench is a jargon. Generally, the insider is called a trench.

The trench is a unique craft of hand-woven carpets in China, created in the 1920s and 1930s. Using electric scissors as a tool, using different techniques and techniques such as cutting, filming, casting, and smashing, the edge of the pattern is formed into a shallow groove-like outline. The artistic effect of “convex embossing” due to the projection of light can make the pattern more Clear, vivid and perfect. And can overcome and correct some of the defects caused by the pattern of the carpet in the process of the process is not beautiful, the line is not round and so on.

In recent years, hand-made carpets in countries such as India and Pakistan have also begun to adopt the cutting process. However, this process has only been adopted in the current carpet weaving, and no such process has appeared in antique carpets. The rug of the antique rug can also be seen in the weaving process. In the weaving process, the part of the pattern is thicker than the base color, so the feeling can be touched. The three-dimensional feeling is very strong. Weaving techniques such as the ancient carpets in Baotou are very common.
