Abrasion is the rubbing a!ay of the "omponent#bres and yarns of the fabri".

Abrasion is of three types :

Plain or $at abrasion % A $at area of material isabraded.

&dge abrasion % 'ind of abrasion !hi"h o""ursat "ollars and folds.

(lex abrasion % Rubbing is a""ompanied by$exing and bending.

hree spe"imen of 1+, mm x 1+, mm are "ut an angle-, to length and edges are sealed !ith rubber adhesi)e.

All these samples along !ith "otton lint are tumbled inthe test "hamber.

yarn.

3. (abri" stru"ture:

If one set of yarn is predominantly on the surfa"e then this set !ill!ear most. Relati)e mobility of $oats helps to absorb the stress.
