摘要

METHOD FOR PREPARATION OF A TARGETED PULP MATERIAL THAT HAS AN INTENSIFIED BRIGHTNESS AND A LARGER RESISTANCE TO THERMAL MALLET, METHOD TO PREVENT THE LOSS OF SHINE PURPOSE OF A LURED ALPHATE PULLED ALPHAVE PULP AND A GREATER RESISTANCE TO THERMAL APPLICATION, METHOD OF OBTAINING A PAPER PRODUCT THAT HAS INTENSIFIED BRIGHTNESS AND A MORE RESISTANCE TO THERMAL APPLICATION, PURPOSE AND FORMULA PULP MATERIAL. Compositions and processes that preserve and enhance gloss and improve the color of pulp or paper when applied during different stages of the papermaking process are identified. The composition and method maintain and / or enhance gloss, prevent yellowing, and enhance the performance of paper products. Used in combination with optical brighteners and / or chelators, the described agents produce a synergistic effect not previously identified in the paper process.
