Treating textile material with non woven fabric rolls

A combination of nonwoven fabric rolls for use in carrying out a method of treating textile material, comprising

• at least one fluid supply roll which includes a first cylindrical core extending coaxially of said fluid supply roll, a number of first nonwoven fabric elements mounted on said first cylindrical core in tight contact relation to one another, and first fluid passageways which are formed internally of said fluid supply roll for intercommunicating connection through first conduit means to an external forcible fluid supply source and which are open to said first nonwoven fabric elements for forcibly letting treatment fluid flow out of the circumferential periphery of said fluid supply roll,
• at least one suction roll opposed in cooperative relationship with said fluid supply roll, and
• said suction roll including a second cylindrical core extending coaxially of said suction roll, a number of second nonwoven fabric elements mounted on said second cylindrical core in tight contact relation to one another, and second fluid passageways which are formed internally of said suction roll for intercommunicating connection through second conduit means to an external negative pressure source and which are open to said second nonwoven fabric elements for forcibly sucking said treatment fluid flowing out of said circumferential periphery of said fluid supply roll.
