Determination Of Wash Fastness Of A Dyed Sample
Determination Of Wash Fastness Of A Dyed Sample Introduction: The resistance to the loss of colour of any dyed or printed material to washing is referred to as its wash fastness. If the dye molecules is not penetrated through the inner structure of fibre polymer system or have not attached to the fibre with strong […]
Determination Of Perspiration Fastness Of A Dyed Sample
Determination Of Perspiration Fastness Of A Dyed Sample Introduction: The garments which come into contact with the body where perspiration is heavy may suffer serious local dis-colouration. This test is intended to determine the resistance of colour of dyed textiles to the action of acid and alkali perspiration. SDC recommended multifibre fabric to the test […]
