Title: Integrity Testing of Fabrics for Cleanroom Garments Matts Ramstorp BioTekPro AB, Malmö and Division of Aerosol Technology, Department of Design Sciences, Lund University, Sweden

Specialized textile fabrics have been used in cleanroom garments for many years. The need for this type of fabric has increased mainly due to the increasing need to protect critical operations in cleanrooms as well as to create a good enough comfort for operators and other personnel. Despite the continuous development of textile fabrics as well as cleanroom garments several and more so, highly critical questions still needs to be answered: • On what ground do manufacturer of textile fabrics and (or) cleanroom garments state that their products are suitable for use in a certain cleanroom class? • How can these fabrics and garments be controlled in order to fulfill the demands stated by end-users as well as regulatory authorities? • How can the life-time of these products be examined and controlled, especially when the garments have to be sterilized prior to use. This presentation covers the general background in regards to the filtration efficiency of cleanroom fabrics and garments. Furthermore, it introduces a new and improved method for testing fabrics as well as cleanroom garments; a method that is more practical and sensitive as compared to traditional methods used today and based on a more concise technical approach. Conclusion During the experiments performed it was quite obvious that the bubble point test has serious drawback when used to study the filtration efficiency and thereby the aging of cleanroom fabrics. The most critical drawbacks are that the equivalent pore diameter is not a good measure of the filtration efficiency of the fabric together with the fact that the bubble point test is operator dependent. The new integrity test method introduced in this presentation is a better method in order to study the homogeneity as well as the filtration efficiency of fabrics and is also a method that is quite easy to use, after a profile of the fabric has been obtained. The new method has been used in industry at a cleanroom laundry company as well as a university in Sweden for two years now. Further results will be published.
