Abstract :

This study was carried out in order to investigate the impact of storage time (5 months) for cotton bales in both humidified and non-humidified conditions, ginned with rollergin and sawgin machine, on fiber quality parameters. In rollergin and sawgin bales kept in humidified environment, it was detected that inner bale moisture increase was regular, and in non-humidified environment it was irregular with the time increase. It had been observed that storage type had not changed the weight value of sawgin bales, but bale weight values of rollergin bales had decreased in non-humidified environment, and it had not changed in humidified environment. In rollergin bales stored in different conditions, with the increase in storage time, it was observed that micronaire (Mic) and elongation (Elg) values had decreased, maturity, reflectance (Rd) had increased; upper half mean length (UHML), uniformity index (UI), short fiber content (SF), fiber strength (Str) and yellowness (+b) had not changed at all. In sawgin bales stored in different storing type, on the other hand, it was detected that storage time had positively affected fiber strength (Str), elongation (Elg) short fiber content (SF), and reflectance (Rd) values and had not caused any change in micronaire (mic), upper half mean length (UHML), uniformity index (UI) and yellowness (+b) values. The result of this study showed that five months storage time (January – May) in both humidified and non-humidified environment had generally not affected fiber quality parameters in a negative way, since the differences investigated in fiber quality parameters remained within the tolerance values (increase or decrease) for the fiber quality characteristics.
