Description
Technical field
The invention belongs to technical field of polymer materials, is related to a kind of new life with specific antibacterial effect
Thing high polymer material：Applications of the PHA PHA in textile preparation.
Background technology
With sharply increasing for production capacity, China has become the main processing base of world's fiber product, but
It is, due to identicalization of product variety, to cause each manufacturing enterprise inevitably to enter low-price competition
Among vicious circle so that the profit margin of enterprise significantly declines, or even loses.It is this to change
State, each enterprise all increase the exploitation dynamics of new product, make every effort to open by differential, functionalization
Hair, creates the new market opportunity, increases new profit growth point for enterprise.
Because in daily life, people can constantly touch various microorganisms, which includes
Some pathogenic bacteria or possible pathogenic bacteria (under certain condition, such as temperature, humidity, can be converted into tool
Have the microorganism of pathogenicity), so as to influence the health of people and normal life.All kinds of textile tools
There is high specific surface area, therefore, usually as the optimal habitat of these microorganisms.Microorganism is being spun
On fabric after amount reproduction, textile may be made peculiar smell occur, and make the weight of pathogenic microorganisms
Want propagating source.Therefore, textile product of the exploitation with certain antibacterial functions has become textile enterprise's innovation
A kind of embodiment of ability.
The preparation method of existing antibiotic fabric can be divided mainly into Physical and chemical method.Physical refers to will be anti-
The methods of microbial inoculum is by soaking, padding, coating, co-blended spinning makes fabric substrate be combined with antiseptic, from
And make fabric that there are certain antibacterial functions.Antibiotic fabric made from this method is because antiseptic only exists substantially
In the top layer of fabric fibre, so, there is not washable, the unabiding shortcoming of antibacterial effect.Chemical method is
Antiseptic is attached on fabric fibre by finger in a manner of chemical bond, and this method can make antiseptic than stronger
Ground is attached on fiber, and antibacterial effect is more lasting, compensate for the deficiency of Physical.In addition, pass through by
Fibrous material with natural antibacterial, such as chitin fiber, hemp, bamboo fibre, with it
Fabric is made by blending in its fiber, and the method for making it have certain long-term antimicrobial efficiency has also been industry
It is widely used.
Except having the material of natural antibacterial as described above, the antiseptic that industry uses at present mainly whether there is
Machine thing (including the metal such as silver, copper, zinc or its ion, and zinc oxide, cupric oxide, ammonium dihydrogen phosphate,
Lithium carbonate etc.) and organic matter (carbamide compounds, anilid class, imidazoles, thiazoles, isothiazole
Ketone derivatives, quaternary ammonium salt, double croak classes, phenols etc., the security of organic antibacterial agent is still under study for action.
In general organic antibacterial agent heat resistance is poor, and easily hydrolysis, the term of validity are shorter).
Patent 92109288.1,200510024709.6,97198782.3,200410005034.6,

201010285121.7,201210311094.5 etc. the technical schemes, be all by that will have antibacterial
The inorganic matter and organic matter of function are blended into fabric；Or by the monomer containing antibacterial group or containing can
The monomer for being converted into antibiotic property group is attached to fiber or fabric face by chemical reaction；Or it will knit
The functional group conversions on fibres surface are the group with antibiotic property, so as to realize the antibiotic property of fabric.Mesh
Before, with the sustainable growth of people's environmental consciousness, to using various inorganic and organic matter as antiseptic
Fabric proposes worry to the long-term safety of human body and environment, therefore, using natural, nontoxic nothing
Harmful material has increasingly obtained the attention of industry as the antibiotic fabric exploitation of antibacterial functions matrix.Patent
201210476977.1,201210475571.1,200910182606.0 use technical schemes be respectively
Natural antimicrobial substance hemp, chitosan, bamboo fibre and the blending of other fibrous materials are spinned, then
The fabric with certain antibacterial functions is made.The antibacterial effect of such scheme is influenceed by the content of antibacterial material
Huge, some not wash resistant (referring to comparative examples 1,2,3), or cost are very high (such as chitin fiber),
Therefore, the application of its extensive industrialization is leveraged.
PHA (PHA) is using reproducible starch as primary raw material, utilizes special biology
The new bio high polymer material of fermentation engineering production, be it is a kind of it is natural, there is fabulous biofacies
The material of capacitive.By changing the process conditions in microorganism and carbon source kind and incubation, can give birth to
Output different structure and the PHA material of performance (kind for having been carried out merchandized handling at present), such as
Poly- 3-hydroxybutyrate ester (P-3HB, abbreviation PHB), poly- 4 hydroxybutyric acid ester (P-4HB), poly- 3-
