It is expensive and the loops are not easy to stand upright.
2. Some companies require the twisting of the loop yarn and the ground wire to improve the weft. However, according to 3Z, it is not too important, because the elasticity and organization of the velvet determine the ground yarn. The ground yarn is polyester, it is easy to overcome the weft at the time of shaping.
The number of charter roads is small, the latitude is not obvious 30" 48 and 44 roads are more common, 26" 42 roads are more common.

The grey fabric is directly dyed after being cut and cut, and the slight horizontal strips and vertical strips are covered after the finished product, and a small amount of shearing is not clear, leaving the ring to increase the gloss of the entire surface (and some inexperienced and rigid QC communication) At the time, it often takes a lot of tongues to explain, depressed, and the suede is chaotic.
