More Information
Summary:Nonwoven fabrics and textiles containing cellulose ester fibers particularly cellulose acetate fibers are thermally bonded. An aqueous plasticizing solution is applied to the surface of a nonwoven web and thereafter the web is thermally bonded to create a thermally bonded nonwoven textile. Alternatively, water can be applied to the dry surface of a nonwoven web containing organic plasticizer treated cellulose ester fibers to create the moistened nonwoven web and thereafter thermally bonding the moistened nonwoven web to make a thermally bonded nonwoven textile. The fabrics exhibit an increase in tensile strength and toughness greater than the individual contributions of water and plasticizer alone and greater than the additive contributions of water and plasticizer alone.
