The breaking strength of paper yarn can be calculated by Formula (64) of Report No. 30, Formula (75) of Report No. 31 and Formula (78) of Report No. 32. Therefore, the following methods can be adopted in the case of the chemical treatment.
1. The method to increase P0 : (Breaking Strength of Raw Paper) by :
a. treating raw fibers b. treating raw papers c. treating tapes
2. The method to increace μ (Friction-Coefficient) by :
d. treating fibers e. treating tapes f. plastering fibers together g. plastering tapes together h. plastering yarns together all of which can be re-arranged as follows :
1) The method to treat raw fibers
2) The method to treat raw papers
3) The method to give the cut materical the treatment liquid instead of water, to twist and to heat the twisted yarn in order to attain the treatment effect
4) The method to give the cut material the treatment liquid, instead of water, to strengthen in the tape stage, and to give water and to twist
5) The method to treat yarns.
By the comparative study on the above 5 methods, 3) method was found to have the best treatment effect.
