Description
Technical field
The present invention relates to a kind of preparation methods of sulphation Banlangen Polysaccharide modified fibre, belong to functional fiber preparation skill
Art field.
Background technique
With stepping up for living standard, the consciousness of people's environmental protection and health is increasingly enhanced.It is well known that bacterium, true
The microorganisms such as bacterium can breed rapidly under the conditions of suitable temperature and humidity and be spread the disease by contact, influence the body of people
Health and normal life, and in the communication process of pathogenic bacteria and all kinds of textiles that skin is in close contact become important
One of medium.Therefore, the anti-microbial property for promoting textile material fiber just seems increasingly important.In recent years, all kinds of antibacterial fabrics
Gradually enter into people's lives.Common chemical classes antibacterial agent be easy to cause in the production and use process environmental pollution and
Skin and respiratory tract are stimulated, so the head for making textile that there is antibiotic property to have become antibacterial fabric using natural green substance
Choosing, also increasingly has been favored by people.
Common chemical modification method include chitin modified, natural fibroin albumen arranges, polybasic carboxylic acid class is modified, sun from
Sonization agent modifier etc..Chitosan is chitin through a kind of deacetylated obtained polysaccharose substance, as a kind of natural alkali
Property polysaccharide, the molecular structure of chitosan is extremely similar to cellulose, have many excellent performances, such as sucting wet air permeability, biology
Compatibility, biodegradability and antibiotic property etc., therefore be widely used in textile industry arrangement, it is frequently used for the anti-of fabric
Fixing finish etc. in bacterium arrangement, anti-crease finishing and dyeing.But many functional finish can not with it is chitin modified after
Fiber crosslink, the washability of the fiber after arrangement is poor, limits their application.
Modern medicine and pharmacology the study found that the plant polyose contained in the Chinese herbal medicine of some plants have anti-bacteria and anti-virus,
It improves immunity of organisms, remove the multiple efficacies such as interior free yl, immunological regulation, reducing blood lipid.Radix Isatidis is as a kind of common
Heat-clearing and detoxifying herb, be generally acknowledge it is one of important with preferable antiviral effect.Banlangen Polysaccharide has immunoregulation effect,
There is certain facilitation to specific immunity and nospecific immunity, is comparatively ideal immunopotentiator；Radix Isatidis simultaneously
The combination activity that polysaccharide can reduce NF- κ B and DNA caused by bacteria lipopolysaccharide (LPS) Stimulated Macrophages strain increases, right
In inhibiting inflammatory reaction related gene expression, the generation of inflammatory factor is reduced, prevention and treatment diseases associated with inflammation has certain curative effect.Therefore
Banlangen Polysaccharide is carried on fabric fibre, to obtain good anti-bacterial effect, the textile with health-care effect be have it is good
The research direction of prospect.
Sulfated polysaccharides is also referred to as polysaccharide sulfate or polysaccharide sulfate, refers to the polysaccharide that sulfate radical is had on polysaccharide hydroxyl,
It is that more a kind of natural or chemically modifying polysaccharides are studied in antiviral polysaccharide, including the various sulfuric acid extracted from animal and plant
Polysaccharide, heparin, natural neutral polysaccharide sulfate derivative and artificial synthesized, semi-synthetic various sulfated polysaccharides.It is straight from plant
The polysaccharide of extraction is connect after the structural modification of Sulfation, conformation is changed, and conformation change is often biologically active variant
The determinant of change.Therefore, the polysaccharide after sulfuric acid-treated shows different from original polysaccharide or enhancing bioactivity.But
It is that sulphation Banlangen Polysaccharide is applied to the fields such as drug and fungicide at present more, there are no sulphation Radix Isatidis and be carried on fiber
Report.
CN102405941 discloses a kind of Radix Isatidis oil microcapsule and a kind of Radix Isatidis oil microcapsule function textile finishing
Agent, by 40~65% Radix Isatidis oil microcapsule lotion, 5~15% wrinkle resistant crosslinking agent, 1.5~5% catalyst, 0.2~
2% bleeding agent, 5~8% softening agent and 10~35.75% water composition；Radix Isatidis oil microcapsule partial size is 5~10 μm,
Its core material and the mass ratio of wall material are 1: 0.5~1.75；Radix Isatidis oil microcapsule fabric finishing agent with functions can make after arranging
Fabric has the multiple functions effect such as Durable antibacterial, antiviral, wrinkle resistant, and fabric is made to have good flexibility and breathe freely
Property.
CN107869048A discloses a kind of preparation method of antibacterial modified natural fiber of functional polysaccharide, using ozone or double
Oxygen water is as oxidant, using titanate as catalyst, the hydroxyl on natural fiber macromolecular chain is oxidized to more reaction and is lived
The aldehyde radical of property；Then oxidized polysaccharide fibers are handled using chitosan solution, amino and oxidized fibre molecule in chitosan molecule
On C=0 directly occur covalent cross-linking reaction, be combined together chitosan and fiber firmly, improve its water-wash resistance, also
Hemicellulose and acetic acid is added as protective agent, prevents fiber to be excessively oxidated, drops low-fiber mechanical performance.It is described modified fine
Dimension has good colourability, bio-compatibility, natural antibacterial performance, but the washing resistance performance of functional polysaccharide is still not
Foot.
There is the method for much attempting functional polysaccharide and fiber being effectively crosslinked load in currently available technology, but mostly
The problems such as it is insufficient that there are polysaccharide adhesions, and polysaccharide falls off from fiber surface after repeatedly washing, polysaccharide-modified fibre technology tool
Be significantly improved space.
Summary of the invention
The present inventor is found surprisingly that the Banlangen Polysaccharide of sulphation not only has relative to untreated Banlangen Polysaccharide
There is better anti-bacteria and anti-virus performance, and by having excellent dyeing ability on pretreated fiber.This may be because
Be Banlangen Polysaccharide after oversulfated processing, sulfuric acid not only on polysaccharide hydroxyl occur esterification, but also on fiber
Other groups sulfonating reaction occurs so that combine the stronger sulfonic group of activity and ester group in polysaccharide molecule, thus and
Fiber generates stronger molecular separating force and chemical bond, obtains having more preferable washability, change in conjunction with closer sulphation Radix Isatidis
Property fiber.On the other hand, pretreatment appropriate is carried out to fiber, the substances such as esters and hemicellulose in fiber can be removed, into
One step improves the binding ability of fiber and Banlangen Polysaccharide, and improves the flexibility and feel of modified fibre.
In addition, design feature of the present invention also according to sulphation Radix Isatidis, treats carrying fiber and is targetedly changed
Property processing, and sulphation Banlangen Polysaccharide load during be added to protective agent and cellulase processing, these reagents produce
Good synergy has been given birth to, the binding strength of sulphation Banlangen Polysaccharide and fiber has been further improved, substantially increases sulphur
It is acidified the water-wash resistance of Banlangen Polysaccharide modified fibre.
