Description
Technical field
The present invention relates to a kind of paper and preparation method thereof, and in particular to a kind of degradable plant fibre paper and its preparation side
Method.
Background technology
With the continuous enhancing of people's environmental protection consciousness, the exploitation of degradation material has become Material Field 21
The study hotspot in century.Either it is the refuse pollution for solving the problems, such as packaging material, or in order to solve increasingly exhausted material
The raw material resources problem of plastics industry of the raw material especially based on petroleum resources, research and development degradation material all have weight
Want meaning.As human being's production and essential fibrous material of living, its discarded object also receives much concern, especially artificial synthesized
Chemical fibre, it is difficult to degrade, it has also become new pollution sources.At present mainly using method of reproduction, combustion method and edman degradation Edman to these
Discarded object is handled, wherein generally acknowledge that the best approach is edman degradation Edman, and in biodegradable, light degradation and thermal degradation this several method
In, biological degradation method again with its original is low, effect is good and it is noticeable.BIODEGRADABLE FIBER MATERIAL refer in certain time and
It can be acted under appropriate natural conditions by microorganism (such as bacterium, fungi, algae) or its secretion in enzyme or chemical breakdown
The lower fibrous material degraded.BIODEGRADABLE FIBER MATERIAL is environment amenable material, and it can help the mankind to reduce
To the burden of environment, modern civilization and the relative equilibrium of nature are kept, therefore by one of majority fibers as 21 century.Can
The synthetic method of biodegradation material mainly has biological synthesis process, chemical synthesis macromolecule method, natural macromolecule modification method etc., its
Middle biological synthesis process is using microorganism or using gene chemical synthesis, is the synthetic method of most vitality and bright prospects.
BIODEGRADABLE FIBER MATERIAL applied to medical domain is typically all nontoxic to human body, can voluntarily be divided in inside of human body
The high polymer material for being absorbed or being excreted after solution.Medical degradable fiber is divided into natural degradable fiber and artificial synthesized drop
Solve the class of fiber two.Natural degradable fibrous material is all taken from organism material or natural materials, is to pass through enzymatic in vivo
Act on and complete degraded, such as collagenous fibres, calcium alginate fibre, poly (hydroxyalkanoate) fiber and chitin kind fiber.People
Work synthesis and degradation fiber have polydioxanone fiber (PDS), vinal (PVA), polyglycollide fibre (PGA) and
