Study On The Preparation Of Tea Tree Oil Viscose Fiber And Its Performance Testing

The paper based on natural antibacterial properties of tea tree oil itself has, in theform of slow~release microcapsules, beta-cyclodextrin as wall material, tea tree oil as thecore material, to make up inclusion compound, and add to a certain proportion inordinary viscose spinning fluid mixing to realize the blend, finally made with somespecial functions of tea tree oil viscose fiber.The paper first tests the main functional compounds of tea tree oil used infraredspectrum identification; influence factors of effect on the preparation of tea tree oilentrapped beta-cyclodextrin complex: tea tree oil and beta-cyclodextrin delivery ratio,inclusion temperature, closure time, three factors in the single factor optimizationexperiment, with tea tree oil pocket rate as the main study object, the optimization designof3factors3levels orthogonal experiment of tea tree oil beta-cyclodextrin inclusion is:putout1ml:8g, inclusion temperature50℃, closure time2.5hours, the tea tree oilpocket at a rate of83.95%, under the condition of the comprehensive score of69.22; Byir spectroscopy and X-ray powder diffraction solid method of inclusion compound,beta-cyclodextrin, tea tree oil, beta-cyclodextrins and physical mixture of the mainfunctional groups of tea tree oil, characteristic peaks were compared to determine if theinclusion successes; With ordinary microscope and electron microscope scanning methodfor beta-cyclodextrin inclusion compound and microcosmic comparison, discovers thatbeta-cyclodextrin as long strip shape, and for the tooth shape of inclusion shape, undermagnified1000times,2000times and8000times electron microscopy conditions ofbeta-cyclodextrin surface contour edge is clear, there was an obvious attachments andgenerate surface of inclusion, hazy outline, that they are not the same kind of material,concluds that tea tree oil molecules may be through the cracks into the beta-cyclodextrin, thus the hydrophobic group within the beta-cyclodextrin to combine, form into inclusioncompound; Using synchronous thermal analyzer analyses the thermal stability of theinclusion compound, finds that after joining into beta-cyclodextrin significantlyimproved the thermal stability of the tea tree oil; Using the method of standard solutioncurve of tea tree oil tests clathrate slow-release performance, finally between35℃and40℃the released rate of tea tree oil is higher, the release can amount to60%, and after5hours getting to release balance; The rheological properties of blend solution curve isused to determine the best inclusion compound with ordinary viscose bulk, blending onthe ratio of1g:8ml, blending temperature of50℃, under this condition after a certainspinning process prepares to tea tree oil viscose fiber.The paper tests the basic mechanical of tea tree oil viscose fiber, the resultsshows that dry strength of tea tree oil viscose fiber slightly larger than ordinary viscose,elongation, by contrast, wet strength fell by50%, numerical slightly smaller comparedwith the ordinary viscose, and elongation; Gas-ms method is used to prove that the mixedviscose fiber includes the main components of the tea tree oil; slow release performanceof viscose fiber was tested by standard curve method, the result is that under normalhuman body temperature0~2hours that tea tree oil release speed is in a straight linerelationship, after4hours getting to the release balance; the paper by AGAR AGARdiffusion method to prove that tea tree oil viscose fiber with antibacterial performanceeffectively.This topic uses the method of blending to realize that viscose fiber material hashealth care function, and it is also the one of the main directions of functional textilematerial research, the research content and the method can be beneficial to the scientificresearch and production after the same type of reference and reference.
