20090133846 | CREPING ADHESIVES COMPRISING BLENDS OF HIGH AND LOW MOLECULAR WEIGHT RESINS - A composition comprising one or more high molecular weight resins and one or more low molecular weight resins in a ratio of about 1:99 to about 99:1 based on polymer actives, wherein said high molecular weight resins are selected from the group consisting of glyoxylated polyacrylamide, crosslinked polyaminoamide and polyaminoamide-epihalohydrin resins having a molecular weight of about 100,000 to about 5,000,000 Dalton and the low molecular weight resins are selected from the group consisting of glyoxylated polyacrylamide, crosslinked polyaminoamide and polyaminoamide-epihalohydrin resins having a molecular weight of less than about 100,000 Dalton and wherein the mole ratio of epihalohydrin to secondary nitrogen atoms in the high and low molecular weight polyaminoamide-epihalohydrin resins is less than about 0.5. and use of the composition for creping paper webs. | 05-28-2009 |
20100086672 | METHOD AND APPARATUS FOR MONITORING AND CONTROLLING THE APPLICATION OF PERFORMANCE ENHANCING MATERIALS TO CREPING CYLINDERS - A method for monitoring and controlling the thickness of coating on a creping cylinder is disclosed. The methodologies involve a coordinated scheme of apparatuses that function to monitor various aspects of a creping cylinder coating so that the thickness of the coating can be determined. | 04-08-2010 |
20110162811 | MODIFYING AGENT FOR YANKEE COATINGS - The invention provides a composition of matter useful for producing very soft high grades of tissue paper. The composition of matter comprises an adhesive composition that includes a glycerol-based polyol. The glycerol-based polyol prevents the composition from becoming brittle and is non-volatile. This allows the composition to become rewetted after creping and allows for strong levels of adhesion even at high temperatures. | 07-07-2011 |
20130078364 | METHOD AND APPARATUS FOR MONITORING AND CONTROLLING THE APPLICATION OF PERFORMANCE ENHANCING MATERIALS TO CREPING CYLINDERS - A method for monitoring and controlling the thickness of coating on a creping cylinder is disclosed. The methodologies involve a coordinated scheme of apparatuses that function to monitor various aspects of a creping cylinder coating so that the thickness of the coating can be determined. | 03-28-2013 |
20130340963 | DEBONDER AND SOFTENER COMPOSITIONS - The invention provides methods and compositions for softening paper. An inventive composition and method of its use softens paper products (like tissue paper) by de-bonding its cellulose fibers and by improving the smoothness of the resulting paper. The invention forms a surfactant-polymer complex that attaches de-bonding non-ionic surfactants to cellulose fibers that would otherwise not be retained by the cellulose fibers. This complex prevents the fibers from bonding with each other and makes the paper product smoother. Best of all, the composition is environmentally superior and is a non-toxic. | 12-26-2013 |
20140110071 | NOVEL CREPING ADHESIVES AND METHODS TO MONITOR AND CONTROL THEIR APPLICATION - This invention is method of creping a paper web comprising a) applying to a rotating creping cylinder an adhesive composition having a pH of about 6.5 to about 8 and comprising one or more vinylamine/N-vinyl formamide polymers composed of about 10 to about 99 mole percent vinylamine monomer and about 90 to about 1 mole percent N-vinylformamide monomer; b) pressing the paper web against the creping cylinder to effect adhesion of the paper web to the creping cylinder; and c) dislodging the paper web from the creping cylinder with a doctor blade. | 04-24-2014 |
20140170302 | METHOD AND APPARATUS FOR MONITORING AND CONTROLLING THE APPLICATION OF PERFORMANCE ENHANCING MATERIALS TO CREPING CYLINDERSTO IMPROVE PROCESS - The invention provides methods and compositions for monitoring and controlling the thickness of coating on a creping cylinder is disclosed. The methodologies involve a coordinated scheme of apparatuses that function to monitor various aspects of a creping cylinder coating so that the thickness of the coating can be determined. | 06-19-2014 |
20140182799 | METHOD OF INCREASING PAPER SURFACE STRENGTH BY USING ACRYLIC ACID/ACRYLAMIDE COPOLYMER IN A SIZE PRESS FORMULATION CONTAINING STARCH - The invention provides methods and compositions for increasing the strengthening effect of a starch coating on paper. The method involves contacting the starch with a synthetic polymer before the starch is cooked. This changes how the starch gelatinizes and how the polymer gets distributed on the paper resulting in greater paper surface strength. | 07-03-2014 |
