ABSTRACT
The present study was carried out to evaluate the effect of trash content and cotton cleaning and find out the behavior of the Egyptian cotton fiber properties in two stages of cleaning at Cotton Research Institute, Egypt. The used Egyptian cotton varieties were taken from product and marketing season of 2024 such as Giza 92, Giza 96, Giza 97 and Giza 98. There was lint cotton grade for each variety; Good/Fully Good for Giza 92 and Giza 97, Fully Good for Giza 96 and Giza 98 and both of Good and Fully Good Fair for all the studied cotton varieties. Measuring trash components and physical fiber properties; there were obvious effect for the presence of trash and cleaning stages for all cotton fiber properties; upper half mean length, micronaire, maturity, fiber strength and degree of yellowness. The most effect of trash was on reflectance percentage. From trash components; non-lint, fiber fragment and dust, both of cleanabiliy and degree of cleaning were calculated for all cotton varieties. No obvious trend of cleanability and degree of cleaning was appeared for G 92, G 96 and G 97. Meanwhile; G 98 as a shorter Egyptian cotton variety gave the highest value of cleanability.
