Effect of lint grades on some physical and structural fiber properties in Egyptian cottons [electronic resource].

Includes reference.

This research was carried out at Grade Res. Dep. Cotton Research Institute. Agric. Res. Center during 2002 seasoll to study the relations between some physical and structural characters for three cotton cultivars. One of them represented Extra- long staple category i.e. Giza 88.whereas the others represented Long staple category i.e. Giza 86 and Giza 90. Two main grades F.G. and F.G.F. and two grade steps Gj F.G. and G.F.I F.G.F. were chosen during this investigation. The results indicated that Giza 88 ranked first in fiber length at 2.5% S.L., micronaire value. fiber strength and stiffness. With respect to the tested grades. fully good (F.G.) and Good /fully good possessed the longest, the strongest and best toughness. Number of convolutions and reversals differed according to tested varieties. Number of reversals were increased in the low grades, while convolutions number did not follow a conspicuous trend.
