A kind of method using the efficient papermaking of polyester fiber
Technical field
The present invention relates to functional paper manufacture field, and in particular to a kind of method using the efficient papermaking of polyester fiber.
Background technology
Paper industry is one of ten big mainstay industry of developed country's national economy.The appearance of laser industry has promoted photoelectricity
The development of industry, it is the pillar industry of information industry.By rapid growth for many years, China's paper industry also gradually walks after 2012
Enter stage of ripeness China's paper industry transition and upgrades in recent years, progressively develop to functional paper direction.Fabric field is developed
The functional paper that is prepared by paper technology of fiber turn into the key of papermaking industrial upgrading.
Deepened continuously with the development of textile industry and to chemical fibre research, have developed increasing chemistry
Fibre new species, chemical fibre have been widely used in manufacturing paper with pulp the paper of various specific uses in paper industry.Polyester fiber
Also known as terylene, it is a kind of important source material for producing speciality paper.Application field of the polyester fiber in papermaking is very wide, including filtering
Material, appliance material, extraordinary false-proof ticket paper, wrapping paper etc., there is the synthetic pulp of resistance to elevated temperatures and insulating properties with other
Material mixing copy paper, can be made into a kind of high temperature resistant polyester fiber insulating paper.But because polyester fiber is typical hydrophobic fibre, copy
Dispersive property during paper in water is very poor, it is necessary to is modified processing.
The hydrophilicity research for improving polyester fiber mainly has two classes:When physical method, by being total to hydroaropic substance
Mixed or composite spinning improves the hydrophily of fiber, or carries out the processing of fiber microporous and fibre section heteromorphosis and improve fiber surface
Wettability energy;Second, chemical method, makes macromolecular have hydrophily, or pass through by introducing hydrophilic monomer block copolymerization
Hydrophilic monomer graft copolymerization, hydrophiling arrangement is carried out in fiber surface.
The B of Chinese invention patent publication number 103981711 discloses a kind of methods of PVA to polyester fiber hydrophilic modifying, will
Polyester fiber is pre-processed under the conditions of Sodium Hydroxide Alkaline, and then polyester fiber is put into PVA, in acetic acid, methanol, sulphur
The GA that mass fraction is 25% is added under sour sour environment, graft modification is carried out to polyester fiber.This method of modifying improves terylene
Hydrophily is obvious, but modified polyester fiber is applied to when in paper-making process fiber and matrix material adhesion strength not
Foot, influences finished paper performance.In addition, producing waste liquid waste gas in production process, environmental requirement is unsatisfactory for, is unfavorable for pushing away on a large scale
Wide production.
Thus, not only need polyester fiber that there is good hydrophily in paper-making process, and need polyester fiber to have
Certain fibrous binding force is bonding with matrix material, is easy to scale copy paper.Obvious existing polyester fiber stills need further
It is modified, can be with efficiency of manufacturing paper with pulp to improve its personality of manufacturing paper with pulp.
The content of the invention
Very poor, fiber and base for dispersive property of the polyester fiber in the prior art in paper-making process in copy paper liquid
Body material adhesion strength deficiency, the low technological deficiency of efficiency of manufacturing paper with pulp, the present invention propose a kind of using the efficient papermaking of polyester fiber
