This is the huge persimmon dyed cotton bag used in a threads factory in mid 20c in Japan. Perhaps used to use for store silk cocoons. 
 
These bags were used by repeatedly patching the cloth over and over again whenever a hole appeared. The kanji characters are stenciled with the name of the thread company.
 
You can hang it as textile art or use it for your product.
