Abstract
The present invention relates to textile technology field, solves the problems, such as that vamp leather primary backing bacterium easy to breed and stink are larger, disclose a kind of preparation method of rtificial leather antibacterial deodourizing flaxen fiber primary backing.The first deposition of titanium oxide on flaxen fiber in this method, then the surface that effect forms three-dimensional netted high molecular polymer and becomes entangled in fiber is crosslinked with beta-cyclodextrin using the trimellitic acid after chloride, the methyl nonyl ketone lauric acid with antibacterial action is finally wrapped in the inside of beta-cyclodextrin molecule.The present invention is using the stink in beta-cyclodextrin absorption surrounding air, to achieve the purpose that deodorization；The double-deck Fungicidal substance is prepared on flaxen fiber, internal layer is the titanium dioxide layer for being deposited on fiber surface, outer layer is the methyl nonyl ketone laurel acid layer being fixed in three-dimensional netted high molecular polymer, the benefit of this structure is the peptizaiton that can greatly increase antibacterial material on fiber, to greatly improve the antibacterial and bactericidal effect of flaxen fiber.
Description
Technical field
The present invention relates to textile technology fields, more particularly, to a kind of rtificial leather antibacterial deodourizing flaxen fiber primary backing
Preparation method.
Background technique
Rtificial leather is in textile cloth or non-woven fabrics base fabric, by foaming or overlay films such as the PVC and PU of various different formulations
Processing and fabricating forms, and can be processed into according to the requirements such as varying strength and color, gloss, floral designs, has designs and varieties
It is various, waterproof performance is good, not care about one's appearance is neat, utilization rate is high and the opposite cheap feature of corium, rtificial leather are increasingly advanced
Manufacture craft is just widely used by the processing and fabricating of double-layer fur.Nowadays, the artificial leather of pole likelihood skin characteristic has production and appears on the market, it
Surface treatment and its fibr tissue of base-material nearly reach the effect of corium, the price of price and domestic first layer lether is not in phase
Under.China Patent Publication No. CN107447537 discloses a kind of preparation method of environment-friendlyleather leather fabric, includes the following steps: to select
Taking leather and base fabric is raw material, leather is moved in stirring instrument, and be passed through water again, is then sprinkled into degreasing agent and oxidation
Agent is moved in rotary drum after bating, and simultaneously into rotary drum after addition mixed dye, completes dyeing, and utilize
Scraper handles the leather surface after dyeing, sprays one layer of spray paint in leather outer surface, base fabric is immersed in colorant, virtue
In the mixed solution of pastil and activating agent, and it is bonded in using biogum etc. the side of leather, forms preliminary environmentally friendly skin
Leather facing material, when this leather is used for vamp, since leather is airtight, the shoes stink passed through is dense, the base fabric in rtificial leather
Positioned at shoes internal layer, stink is remained after wearing for a long time, in base fabric and breeds a large amount of bacteriums, causes foot's fungal infection.
Summary of the invention
The present invention is mentioned to overcome the problems, such as that prior technical shoes leather primary backing bacterium easy to breed and stink are larger
For a kind of preparation method of rtificial leather antibacterial deodourizing flaxen fiber primary backing.
To achieve the goals above, the invention adopts the following technical scheme: a kind of rtificial leather antibacterial deodourizing flaxen fiber
The preparation method of primary backing, comprising the following steps:
1) titanium sulfate is added to the water to stir evenly and is configured to the titanium sulfate aqueous solution that mass fraction is 2~5%, it then will be numb fine
It ties up fabric to immerse in titanium sulfate aqueous solution, is heated to boiling, flow back 1~3h, takes out fabric after cooling, is put into vacuum oven
It is dry, obtain flaxen fiber fabric 1；
2) trimellitic acid is added in thionyl chloride, the mass ratio of trimellitic acid and thionyl chloride is 1:20~30, is added
