다국어 초록 (Multilingual Abstract)

Various properties of cotton handsheet were measured to solve the problem of deformation while storing guar gum(natural polymer) and to improve strength and retention by synthetic polymers(A-PAM,C-PAM, CMC). The results of this study were summarized as follow.

The cotton handsheet with 0.2% of A-PAM showed the best tensile index and folding endurance.

Retention of fines and fillers in pulp slurry with 0.2% and 0.3% of A-PAM were more excellent than that with guar gum.
