Description

A kind of preparation process of novel chitosan anti-bacterial fibre
Technical field
The present invention relates to anti-bacterial fibre fields, relate in particular to a kind of preparation process of novel chitosan anti-bacterial fibre.
Background technology
Chitin also known as chitin, chemical constitution is similar to fiber, largely exists and the crust of the animals such as shrimp, crab, insect It is interior.Chitosan is the product that chitin deacetylation reaches 70% or more.A large amount of amino is carried in chitosan molecule chain structure, In electropositive, there is good anti-microbial property.Current chitin or chitosan anti-bacteria fiber main preparation methods has:1, crust Element/chitosan direct fabrics, method are that chitin/chitosan dissolving is first made into spinning solution in a solvent, through spinneret, are coagulated Gu, stretch, washing, drying and other steps fiber is made;2, coating impregnates general fibre in chitin/chitosan solution Afterwards, obtained through being dehydrated, drying;3, co-blended spinning method;It is obtained one is chitin is worn into and is added to spinning solution after attritive powder Blended fiber, the second is chitin/chitosan is with fibrous raw material co-dissolve, spinning obtains blended fiber in a solvent.However, Fiber prepared by the above method has certain defect.Pure chitin/chitosan fiber selling at exorbitant prices, and intensity is relatively It is low.Coated fiber and blended fiber be not water-fastness, and as washing times increase, antibacterial effect can continuously decrease.
Chinese patent application publication No. " CN107929794A " discloses a kind of cellulose-chitosan oligosaccharide based on chemical crosslinking Composite auxiliary material and preparation method thereof, the composite auxiliary material include epoxy silane coupling agent, cellulose and chitosan or chitosan derivative Object is evenly coated at the surface of cellulose skeleton by epoxy silane coupling agent crosslinking;Preparation method includes:It is suspension mixed Synthesis, the synthesis of the cellulose based on chemical crosslinking-chitosan oligosaccharide combine dressing.The method of the patent is simple, easily operated, cost It is low, environmental protection;The cellulose based on chemical crosslinking-chitosan combine dressing that the patent obtains has good mechanicalness and soft Property, uptake is big and good permeability, which, which avoids, makes the Skin Cell of wound using the dissolution of process small molecular At damage, blood coagulation can be promoted and avoid wound infection, had wide practical use in medical dressing field.But the patent be by Chitosan, epoxy silane coupling agent and cellulose, which are mixed together, to be reacted, and a large amount of raw material, but also chitosan are not only wasted It is low with the grafting rate of cellulose.
Invention content
It is an object of the invention to solve the above-mentioned problems in the prior art, it is fine to provide a kind of novel chitosan antibacterial The preparation process of dimension.The present invention uses crosslinking technology, and chitosan oligosaccharide and cellulose fibre are effectively connected, and the chitosan oligosaccharide after grafting is fine Dimension has acid-fast alkali-proof performance, ensures that fiber still has good antibiotic property after the methods of dyeing, washing, drying are handled Energy;And the grafting rate of chitosan and cellulose is high, and wastage of material is few, and production cost is low.
To achieve the above object, the technical solution adopted by the present invention is as follows:
A kind of preparation process of novel chitosan anti-bacterial fibre, which is characterized in that include the following steps:
(1)The preparation of raw material
A, in retort, cellulose fibre is added in the sodium hydroxide solution of a concentration of 1-5% and is removed for soaking 12-18 hours Surface impurity, clear water is gone to wash to neutrality, be dehydrated, drying obtains pretreated cellulose fibre;
B, acetic acid is added in the silane coupling agent kh560 solution that configuration concentration is 4%, is uniformly mixed, and adjusting pH value is 3-5;
C, sodium hydroxide is added in the chitosan solution of a concentration of 2-5%, is uniformly mixed, and adjusting pH value is 9-11;(2)It is silane coupled The preparation of agent kh560 graft fibres
In retort, by bath raio 1:20 by step(1)Pretreated cellulose fibre is immersed in step in A(1)Silane in B It in coupling agent kh560 solution, stirs evenly, is heated to 60-70 DEG C, keep the temperature 2-6h, clear water washing is dehydrated, and drying obtains silane Coupling agent kh560 graft fibres;
(3)The preparation of novel chitosan anti-bacterial fibre
In retort, by bath raio 1:10 by step(2)The cellulose fibre and step of gained(1)The chitosan solution that C is prepared, It stirs evenly, is heated to 88-96 DEG C, insulation reaction 2-6h, clear water washing is dehydrated, and drying obtains chitosan anti-bacteria fiber.
Advantage using the present invention is:
One, for cellulose fibre of the present invention after sodium hydroxide solution is handled, the hydroxyl on activated fiber cellulose fiber makes subsequent reactions It is easier to make for.Silane coupling agent kh560 is as crosslinking agent, and cellulose fibre is slowly anti-in acid condition with treated It answers, to ensure that the activated group on the silicone hydroxyl and fiber that are generated after kh560 hydrolysis reacts, generates stable silicon oxygen bond, And epoxy group is carried after the completion of reacting on fiber, can be reacted with chitosan.The hydroxyl carried on chitosan and fibre Ring-opening polymerisation occurs under alkaline hot conditions for the epoxy group carried on cellulose fiber, and fiber and chitosan are logical after the completion of reaction It crosses silane coupling agent kh560 to crosslink, grafting rate is high, obtains chitosan graft cellulose fibre, reaches anti-using chitosan The purpose of bacterium.
Two, the present invention uses crosslinking technology, chitosan oligosaccharide and cellulose fibre is effectively connected, the chitosan oligosaccharide fiber after grafting With acid-fast alkali-proof performance, ensure that fiber still has good anti-microbial property after the methods of dyeing, washing, drying are handled; And the grafting rate of chitosan and cellulose is high, and wastage of material is few, and production cost is low.
Three, the present invention is by chitosan graft on cellulose fibre, and due to being to be chemically crosslinked, the chitin fiber of generation is plain The performance that fiber has intensity high, water-fastness, ensure that antibiotic property and practicability.
Four, 12-18h in the sodium hydroxide solution of a concentration of 1-5% is added in cellulose fibre of the present invention, can ensure in this way The impurity such as the greasy dirt of fiber surface are cleaned, and fiber has certain swelling, more conducively increases subsequent reactions degree.
Five, acetic acid is added in the silane coupling agent kh560 solution that configuration concentration of the present invention is 4%, and adjusting pH value is 3-5, Under the ph values, silane coupler solution is more stable, will not generate precipitation.
Six, the present invention presses bath raio 1:20 by step(1)In the silane coupling agent that is immersed in of pretreated cellulose fibre In kh560 solution, it is heated to 60-70 DEG C, keeps the temperature 2-6h, under this condition, silane coupling agent is maximum with fiber-reactive degree, and Silane coupling agent is more stable during the reaction, will not generate a large amount of polysiloxanes, ensures silane coupling agent on fiber Content will not waste reagent.
Seven, compound concentration of the present invention is the chitosan solution of 2-5%, and sodium hydroxide is added, and adjusting pH value is 9-11, this is dense Degree can ensure the smooth dissolving of chitosan, which can ensure being smoothed out for chitosan and fiber-reactive.
Eight, the present invention presses bath raio 1:10 mix cellulose fibre with chitosan solution, are heated to 88-96 DEG C, heat preservation is anti- 2-6h, washing, drying is answered under this condition, fiber reacts more complete with chitosan oligosaccharide, to can make full use of chitosan, Bu Huizao At the waste of reagent.
