Abstract
Discusses properties of regenerated fibres and prospects of the pulp industry in Pakistan. Raw materials in the form of bamboo, wood, grass, golpatta, cotton, linters, straw, bagasse and jute sticks are reported to be in Pakistan in abundance. The pulping processes described are, kraft pulping. neutral sulphite semichemical pulping and cold soda pulping. The results show that Sundri wood can be easily reduced to a strong pulp by the kraft process. The unbleached pulp was found suitable for the manufacture of brown paper and bleached pulp for writing paper. The bleached neutral sulphite pulps have strength similar to that of bleached kraft pulps. The cold soda pulps were not easily bleached and did not respond to the brightening agents such as peroxide or hydrosulphite. The cooking schedules of the processes and properties of the pulps are tabulated.
