Abstract
AbstractIn this study, we investigated the relationships between the thermal properties versus maturity and fineness (H) of 80 selected cotton fiber samples. The instrument measurements for maturity and H were (1) micronaire as determined with a high‐volume instrument, (2) maturity ratio and H as determined with an advanced fiber information system, and (3) gravimetric H as determined by the cut‐and‐weigh method. Three regions of thermal decomposition were observed between 37 and 150°C for region I, between 225 and 425°C for region II, and between 425 and 600°C for region III. Complete decomposition of the fiber occurred at 600°C. The results showed significant effects of the H/maturity indicators on the weight loss and the peak temperatures in regions II and III. High micronaires (coarse or very mature fibers), high maturity ratios, and low standard H values were associated with low weight losses. However, high weight losses were associated with high primary cell wall areas per unit mass. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 3476–3482, 2007
