The cotton dust standard applies to the elastic fabric industry. We wish to thank you for the videotape Mr. Stig Bolgen of your Association sent demonstrating two different types of looms producing narrow fabrics. After having reviewed the tape, we now provide the clarification you requested. Also, the Agency is unaware of any reason why the dust from unwashed cotton used in braiding operations would be any different from dust from unwashed cotton used in weaving.
Exemptions apply, however, if washed cotton only is used.
I appreciate the opportunity to address your concerns. Please do not hesitate to contact me again if you have further questions.
