Definitions
- This invention relates to a process for making paper. More particularly, it relates to a process for making paper which comprises forming a sheet from a pulp slurry containing a neutral sizing agent and optionally a filler using a specific cationic polymer as a paper quality improver.
- the neutral or alkaline papermaking process has advantages such as (1) a smaller energy for beating is used; (2) corrosion of machine is less; (3) the white water system can be closed; (4) selection of fillers is not restricted and cheap calcium carbonate can be used; (5) deterioration of paper with time is less; (6) printability of paper is good, and the like.
- the neutral or alkaline papermaking process has drawbacks such as (1) expensive neutral sizing agents such as alkylketene dimers, alkenylsuccinic anhydrides, etc. must be used instead of cheap rosin sizing agents, and further, such agents are poor in anchoring onto the pulp; (2) fillers are poor in anchoring onto the pulp; (3) when the amount of calcium carbonate is increased, the strength of paper is lowered; and the like.
- expensive neutral sizing agents such as alkylketene dimers, alkenylsuccinic anhydrides, etc. must be used instead of cheap rosin sizing agents, and further, such agents are poor in anchoring onto the pulp; (2) fillers are poor in anchoring onto the pulp; (3) when the amount of calcium carbonate is increased, the strength of paper is lowered; and the like.
- copolymer comprising predominantly (meth)acrylamide and a quaternary product of dimethylaminoethyl(meth)acrylamide, but it is still poor in the paper strength reinforcing effect, and the sizing agent is poor in anchoring effect.
- copolymer comprising predominantly (meth)acrylamide and a quaternary product of dimethylaminopropyl(meth)acrylamide, but it is still poor in the paper strength reinforcing effect like the above polymer, and the sizing agent is poor in anchoring effect and hence good sizing effect can not be achieved.
- Japanese Patent Second Publication (Kokoku) No. 12521/1972 it is disclosed in Japanese Patent Second Publication (Kokoku) No. 12521/1972 to use a polymer having a partial quaternary group which is produced by copolymerizing diallylamine and a copolymerizable vinyl monomer [e.g. (meth)acrylamide], followed by modifying with a'n agent for converting into quaternary group.
- a polymer is particularly insufficient in anchoring of the sizing agent and hence can not give good sizing effect, while the paper strength reinforcing effect is improved.
- the present inventors have intensively studied on an improved process for making a paper having sufficient sizing effect and excellent paper strength owing to the excellent yielding effect of each additives in the papermaking process particularly under neutral or alkaline condition, by using a neutral sizing agent and optionally filler, and the present invention has been accomplished.
