PROCEDURES:
STEP 1: TAKE TUFTS OF FIBRES AND OPEN IT BY MEANS OF HAND
STEP 2: TAKE 200 GMS OF OPENED FIBRES BY MEANS OF A SENSITIVE ELECTRONIC
BALANCE

FIBRES ON A CONDITIONING CABINET AT ABOUT 150 DEG CENTRIGRADE FOR ONE HOUR
STEP 4: TAKE OUT THE CONDITIONED FIBRE AND WEIGH IT ON THE SENSITIVE
BALANCE QUICKLY

WEIGHT OF OPENED FIBRES BEFORE CONDITIONING = W1 GM
WEIGHT OF OPENED FIBRES AFTER CONDITIONING = W2 GM
MOISTURE REGAIN % = (WI – W2) X100
