摘要： The invention provides a composition of matter used to produce very soft high grades of tissue paper. The composition of matter comprises a PAE resin acidified with a multifunctional acid. The multifunctional acid includes but is not limited to carboxyl and sulfonyl. The acid has a functional group selected from carboxyl and sulfonyl and a functional group selected from carboxyl, sulfonyl, hydroxyl, lactone, phenol, amine and heterocycle. The PAE resin facilitates the use of an adhesive in a Yankee Dryer apparatus that is durable when the adhesive is wet but remains soft when the adhesive becomes dry. These properties allow the adhesive to be strong and remain engaged to the dryer apparatus when wet but be easily removed by the creping blade when dry.

摘要： The invention embodies methods and apparatuses to monitor and control the characteristics of a creping process. The method involves measuring optical properties of various points along a creped paper sheet and converting those measurements into characteristic defining data. The invention allows for determining the magnitude and distribution of crepe structures and their frequency and distribution. This allows for the generation of information that is accurate and is much more reliable than the coarse guessing that is currently used in the industry. Feeding this information to papermaking process equipment can result in increases in both quality and efficiency in papermaking.

摘要： A method for target application of a Performance Enhancing Material to a creping cylinder in order to improve a tissue making operation is described and claimed. The method involves dividing the creping cylinder into Zones and then applying the desired Performance Enhancing Material on a Zone by Zone basis such that each Zone has the optimal Performance Enhancing Material present. Furthermore, a method to ascertain the amount and pattern of application of the Performance Enhancing Material used on the creping cylinder is described and claimed. This method involves adding an inert fluorescent tracer to said Performance Enhancing Material and then to use a fluorometer to look for the tracer on the creping cylinder, and/or on the creped tissue product and/or in the water removed from the felt.

摘要： Improved halogen-free Yankee Dryer adhesives based on cross linked cat ionic polyaminoamide polymers are described. The adhesives are obtained by crosslinking a backbone cationic polymer formed by reacting a difunctional carboxylic acid with a polyamine containing at least one secondary amine, said crosslinking achieved by the use of a multi-functional aidehyde. The preferred adhesive is that obtained by reacting adipic acid with diethylenetriamine, at essentially equimolar ratios of from about 1.2: 1.0 to about 1.0: 1.2, and then crosslinking with a dialdehyde selected from glutaraldehyde, glyoxal, or mixtures thereof. Improved adhesion and peel strength are obtained when using the new materials as compared to materials now commercially used.

摘要： The invention is directed towards methods and compositions for improving the sizing of paper using PAE. Proper sizing of paper requires that a sizing agent adequately disperse so as to evenly distribute on the paper. Proper sizing also requires that the agent not cause runnability or chemical problems with other materials or equipment used in the papermaking process. PAE displays unexpected attributes that allow it to disperse sizing agents. Best of all it is not subject to the same overdose effect of typical emulsifiers such as cationic starch. As a result PAE is an excellent option for use in sizing paper.

摘要： 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.
