Determining Dust and Trash Contents of Cottons with the Cotton Particulates Analyzer
1986
Deluca, L.B.
Separate algebraic relationships were established between coarse and respirable dust fractions and trash and respirable dust fractions from gravimetric measurements made with the cotton particulates analyzer, CPA, on multiple cleaning passes for each of two ginned cottons. One cotton had a low and the second a high trash content. Each set of these equations could be combined into a generalized equation for both cottons. CPA gravimetric data were compared with other methods for measuring dust and trash in cotton. Multiple cleaning passes of a low trash cotton were used to find re lationships between CPA and Shirley analyzer lint and trash fraction gravirrietric data. The relationship between CPA respirable dust and trash fractions will be used in Part II of this series to evaluate other methods of measuring dust and trash in ginned cottons.
