I am not very sure what you really need when you say listing. If you mean a listing of companies that deal with clothing accessories. I don’t think or I have not come across such but I know that I china.
There are many large markets for clothing accessories in many cities in China where companies has some show rooms for different types of accessories. Except you are looking for a few specific accessories I would suggest such open markets with thousands of showrooms and variety of items instead of factories.
