Lining paper, current raw materials for production are mainly timber, for producing true qualities water suction lining paper rarely seen correlation both at home and abroad using gold and silver grass
It reports, and research is very few, exactly necessity of this invention.
With the raising of people's living standard, paper for daily use rapidly becomes most close with people's relationship in the modern life
One of consumer goods.The production of paper for daily use, the level of consumption are not only national people's quality of the life and paper industry technology water
Flat mark, and be the mark of social civilization level.The increase year by year of aging populations quantity has become in order to which the world is permitted at present
The problem of multinational facing.By taking China as an example, China in 2016 60 years old and the above old man are 2.12 hundred million people, account for the total people in China
The ratio of mouth is 15.5%, and 65 years old and the above old man are 1.37 hundred million people, and the ratio for accounting for China's total population is 10.1%, illustrates China
Aging country is stepped into.Elderly population medical treatment, take care of, nursing, rehabilitation in terms of demand rapid growth, to defending
Production-goods source and Service Source all bring huge new challenge, also bring to the market exploitation of old incontinence health product unlimited latent
Power, and China has put into effect one family can give birth to the family planning policy of two children, also gives absorbency hygiene market
Very big current demand is brought, in addition the excellent hygiene market demand of women increases again and again.Therefore one women of an older man and a youngster
Three big crowds are the main forces of consumption, and comparatively his (she) demand is rigid, and the consumption idea of health environment-friendly

Phase, female menstrual period, old man's incontinence phase etc.) it uses, it can effectively reduce or reduce the probability of pathogenic infection and allergic stimulated.Therefore
It develops environmentally protective water suction lining paper product and has a vast market development space.
Since the quality requirement of the water suction lining paper of production is relatively high, insider thinks the best raw material of lining paper that absorbs water at present
It is bleached softwood wood-fibred.And China's wood raw material is by cultivated area, growth cycle, the ecological balance, production cost and environmental protection
Etc. the constraints of factors lead to its limits throughput so that domestic wood fiber raw material supply is difficult to meet in the future for a long period of time
The raw materials requirement of relevant industries.Existing bleached wood pulp is mostly import, brings larger cost of material pressure to domestic relevant industries,
For these reasons, the new type natural of suitable China's national situation, renewable cellulose fibre how to be developed to make up wood raw material
It is insufficient；How the improvement of preparation flow and technology and equipment etc. is passed through, and the quality for preparing high added value conforms to
The water suction lining paper asked meets the needs of market as important topic urgently to be resolved.On the one hand make the lining paper production field increasing that absorbs water

80-120 (needlebush 70-150), needle of the fibre morphology and content and optimum of gold and silver grass as water suction lining paper raw materials for production
Wood is similar, and therefore, gold and silver grass has the genetic prerequisite of preparation water suction lining paper, but gold and silver grass knot is more and section portion is more developed,
Section portion surrounding often has hard spinule, and epidermal structure contains more pentose class hemicellulose, fatty wax compared with compacted mass
The non-cellulosic impurities ingredient such as matter, ash content and heteroproteose cell, it is in addition also soft, stubby parenchyma cell composition containing part
Gold and silver grass marrow, in the prior art without the content of report this respect.
Presently commercially available water suction lining paper is almost that bleached pulp produces entirely, and bleaching mostly uses efficient chlorine dioxide etc. to float containing chlorine
Agent bleaching, some businessmans are to meet high whiteness and good visual effect, artificial to add the disabling additive such as fluorescent whitening agent, are caused
Bleach paragraph chemicals dosage and equipment investment increase, and pulping yield decline, personnel labor intensity increases, and the production cost increases
Problem, and bleaching effluent (contain a large amount of COD and BOD, and a large amount of chloroform, chloro phenol compound, chloro dioxin and
The toxic chlorinatedorganic such as furans) the big problem of processing difficulty up to standard, thus bring the destructiveness and life to ecological environment
The serious problems such as the harmfulness of object.And bleached pulp since fiber have passed through bleaching process, have to drop by depolymerization by fiber
Solution causes fines content in water suction lining paper more, to its physical strength, water imbibition, bulk, flexibility and gas permeability etc.
Index causes adverse effect, to influence the qualification rate of product.
