Abstract:
Physical properties of pulping properties of Japanese larch(Larix kaempferi) in different ages(12,15 and 23 years) were investigated. As a result, the physical properties of KP unbleached pulp were close to B grade national standard of unbleached softwood KP pulp, those of KP bleached pulp reached A grade national standard of bleached softwood KP pulp. The physical properties(except whiteness) of AS-AQ pulp,including unbleached pulp and bleached pulp, all reached A grade national standard. Moreover, the tensile strength index, breaking length, folding endurance and burst index of AS-AQ pulp were higher than those of KP pulp. However, the tearing index was opposite.
