Abstract

See full text

100 parts by dry weight of latex, approximately, are used for about 45 to 140 parts by dry weight of fibrous mixture. Manufacture particularly by double flocculation (addition of each flocculating agent partly before and partly after the addition of latex). Very good properties, particularly breakage strength and delamination resistance.
