Lyocell纤维纺丝工艺对并丝量的影响 Title:TheImpactofSpinningProcessontheBlendRatioofLyocellFiber Introduction: Lyocellfiber,alsoknownasTencel,isatypeofcellulosicfiberthatisderivedfromwoodpulp.Itisknownforitsexcellentpropertiessuchashighstrength,goodmoistureabsorption,andeco-friendlyproductionprocess.Lyocellfiberhasgainedsignificantattentioninthetextileindustryduetoitsversatilityandsustainablenature.ThisstudyaimstoinvestigatetheinfluenceofthespinningprocessontheblendratioofLyocellfiber,specificallyinrelationtotheblendratioofotherfibersinthespinningprocess. Methods: TounderstandtheimpactofspinningprocessesontheblendratioofLyocellfiber,severalspinningtechniqueswereexamined.Differentparameterssuchassolventconcentration,spinningtemperature,andspinningspeedwerevaried,andtheireffectsontheblendratiowereobserved.TheblendratioofLyocellfiberwasdeterminedbyanalyzingtheweightpercentageofLyocellfiberinthefinalproduct. Results: TheresultsshowedthatthespinningprocesssignificantlyinfluencedtheblendratioofLyocellfiber.Firstly,thesolventconcentrationhadasignificanteffectontheblendratio.HighersolventconcentrationledtoahigherblendratioofLyocellfiber,indicatingthatamoreconcentratedsolutionresultedinagreaterincorporationofLyocellfiberinthefinalproduct.Secondly,thespinningtemperaturealsocontributedtotheblendratio.HigherspinningtemperaturesincreasedtheblendratioofLyocellfiber,suggestingthatelevatedtemperaturesfacilitatedthedissolutionofLyocellfiberinthesolvent.Lastly,thespinningspeedinfluencedtheblendratio,withhigherspinningspeedsresultinginalowerblendratioofLyocellfiber.ThisindicatedthatincreasedspinningspeedshinderedtheproperincorporationofLyocellfiberinthespinningprocess. Discussion: TheobservedrelationshipbetweenspinningparametersandtheblendratioofLyocellfibercanbeexplainedbythesolubilityofthefiberinthespinningsolvent.Lyocellfiberhasahighersolubilityincertainsolvents,suchasN-methylmorpholine-N-oxide(NMMO),whichiscommonlyusedintheLyocellspinningprocess.Therefore,highersolventconcentrationsandtemperatu
