Why is the elastic ribbon of gold and silver silk easy to be drawn or arched?

　　One is the reason of silk itself:

　　Gold and silver silk has a variety of qualities, and the yarn produced in Jiangsu, Zhejiang or Fujian is poor and easy to break.

　　Another reason is:

　　The warp and weft density of the ribbon is too high, and the gold and silver wires are not easy to open. Pulling yarn on details will also have an impact,

　　When the gold and silver silk yarn and the fish silk yarn are woven synchronously, it is normal for the machine to scrape one or two yarns when it is moving.

　　When it is not smooth to open and there is an uneven elastic force of the rubber root wire inside, it will arch.
