Volume 3, Guidelines for Fabrics and Bags, provides a comprehensive guide for the procurement of fiberglass filter bags for utility baghouses. Utility baghouse operators must have a knowledge of fabric and bag construction to specify and obtain fiberglass filter bags that will provide food service in their baghouses. This volume describes the type of glass used in fabric filter bags, the properties of glass that enable a bag made from fiberglass fabric to withstand baghouse operating conditions, and the manufacturing of fiberglass filaments, strands and yarns. The types of weaves most commonly used are included in a discussion of the production of fiberglass filter fabric, and the types of finishes used on bag fabrics to lubricate and protect the glass at high temperatures are described. In addition, this volume contains an explanation of proper filter bag construction procedures including lay-up and cutting, stitching, seaming, cuffing, ringing, fabricating caps, inspecting, and packaging. A list of bag manufacturers and a cross-reference of model and style numbers of these manufacturers is provided. Guidance is provided for the preparation of specifications and quality control procedures for the acquisition of filter bags, along with a discussion of the test methods used to assure that the procurement specifications have been met. The steps involved in the installation of filter bags are explained. These steps include the inspection of bags when received; storage of bags; preparation, precautions, and procedures for hanging bags; attachment to thimbles at the tubesheet; attachment to bag suspension systems; tensioning; inspection; and retensioning. Finally, the advantages and disadvantages of synthetic fabric alternatives to glass are reviewed. At the end of this publication, an Appendix provides an example of a utility bag specification to aid in bag procurement.
