AATCC 30 耐真菌活性，纺织品材料的评定：纺织品材料耐霉菌防腐烂 Copyright ?? 2005 American Association of Textile Chemists and Colorists AATCC Technical Manual /2006 TM 30-2004 81 Developed in 1946 by AATCC Commit- tee RA31; revised 1952, 1957, 198 1981, 1987, 1988 (with title change), 1993, 1999; reaffirmed 1970, 1974, 1979, 1989, 1998; editorially revised and reaffirmed 1986, 2004. 1. General Purpose and Scope 1.1 The two purposes of this test method are to determine the susceptibil- ity of textile materials to mildew and rot and to evaluate the efficacy of fungicides on textile materials. 2. Principle 2.1 Tests I, II, III and IV can be used, singly or in combination, depending on the type of exposure to which the textile material will be subjected. For example, if the final product will come in contact with soil, Test I, which simulates this ex- posure, should be used; if the finished product will never come in contact with soil or tropical conditions, a much less severe test (e.g., II or III) should be used. Test II is specifically designed for cellu- lose-containing materials while Test III is for all others. For all materials intended for outdoor and above ground use, Test IV should be used. The two important considerations when evaluating textile materials in relation to fungal growth are (1) the actual deterioration of the textile product (rot), and (2) growth not neces- sarily deteriorating the product but mak- ing it unsightly (mildewy) often with an unpleasant and musty odor. 2.2 Certain pre-exposures of textile products may be indicated when specific end-uses are critical (see Appendix A). When the end-use will be near high tem- perature and the fungicide may be vola- tile, a preliminary oven exposure may be desired. When the end-use will be in tropical exposures or outside with rainfall present, a leaching exposure should be performed before mildew evaluation is made. When at all possible, the textile material should be exposed to the ex- pected conditions of use prior t
