Evaluation of Egyptian cotton cleaning efficiency by analysis of trash particle size distribution

Abstract EN

The aim of this work is evaluation of Egyptian cottons cleanability by blowroom .

Where eleven Egyptian cotton varieties were processed through blowroom line.

Cotton samples from bale and from output of successive opening and cleaning machines were tested using Advanced Fibre Information System (AFIS) for thrash content.

Trash content and as cunt/g are considered.

Blowroom cleaning efficiency of the different cottons is calculated and the different cotton varieties are classified to three Groups : low, medium and high resistance to cleaning.

For the three groups of different cleaning resistance trash particle size distribution for the different cotton samples is analyzed as two distributions .

The first is dust size distribution ( size<500μ m) and the second is SCI size distribution (size > 500μ m). Effect of successive opening and cleaning machines on the two distributions is discussed.

The results showed that Blowroom cleaning efficiency of the investigated cottons ranged from 39 % to 84 % and cotton cleanability is an effective factor amomgst the factors affecting blowroom cleaning efficiency.

Data showed that successive blowroom machines have an effect on particle size distribution
