    摘要: The invention relates to a cellulose fiber coated with a coating agent which contains a mixture comprising urea, nonionic surfactants, and antioxidants. The coated cellulose fiber is characterized in that the tensile strength of said fiber is up to four times greater than the tensile strength of the corresponding uncoated cellulose fiber after a defined thermal aging process. The average degree of polymerization of the coated cellulose fiber material is up to six times greater than the remaining degree of polymerization of an uncoated cellulose fiber after the same aging procedure. The invention further relates to thermal aging methods for identifying effective stabilizers and for characterizing coated cellulose fibers and filaments with improved thermostability.
