I don't seem to have anything on textile conservation in my library but you might want to see if the Textile Museum (http://www.textilemuseum.org/) in DC has any resources available. This might be of interest:
Ask-a-Curator, Ask-a-Conservator This ongoing program, held the first Wednesday of every month (September through May) from 10:30 am to 1 pm, gives visitors the opportunity to learn more about their own textiles from Textile Museum curatorial and conservation staff. While Museum curators specialize in the textile arts of non-Western cultures, the conservation staff can answer questions about caring for textiles produced worldwide. Fee: free/members; $5/non-members. No reservations are required.
