Abstract

A new prototype Trash extractor for cleaning mechanical harvested Egyptian cotton (extra-long staple) must be adapted using local materials. The attempt was to develop the Egyptian scutchers to receive mechanically harvested seed cotton.piker through season 2005 at El-Karada Farm — Kafr El-Sheikh Governorate. It was evaluated under different operational conditions included saw drum speeds, feed rates and cotton fiber moisture contents on physical fiber properties 2.5% span length, 50% span length, fiber length uniformity ratio, color reflectance, color yellowness and seed cotton grade. The results showed that the new design prototype extractor produced suitable amount of 2.5% and 50% span length; fiber length uniformity ratio; color reflectance (Rd) and seed cotton grade . Also, results showed that color yellowness (+b) was low at all combination experimental levels.
