what are Bamber chiffon and Chinese chiffon?

I was buying clothes online but these types of chiffons are getting really confusing. Can anyone please tell me what is the difference between Bamber Chiffon and Chinese Chiffon?
Both are crinkle chiffon. I know chinese chiffon is ‘pure’ crinkle chiffon but dont know about bamber chiffon. Its a little cheaper than Chinese Chiffon.
Please help, anyone! Im really confused :frowning:
