九州体育娱乐app一種識別幼兒園服裝面料成分的簡單方法:燃燒法。Asimplemethodtoidentifythecomponentsofkindergartenclothingfabric:combustionmethod.在幼兒園是煙的下擺一縷經紗和緯紗,布用火點燃,觀察燃燒火焰的狀態,聞燒傷后的織物紗線的氣味,看燃燒后的殘余,因此判斷和幼兒園把織物耐久性標簽內容是一致的,識別結構內容的真實性。Inkindergarten,thereisathreadofwarpandweftunderthesmoke.Theclothisignitedbyfire.Observethestateoftheburningflame,smellthesmelloftheburntfabricyarn,andseetheresidueaftertheburning.Therefore,judgethatthecontentofthedurabilitylabelofthefabricisconsistentwiththatofthekindergarten,andidentifytheauthenticityofthestructuralcontent.棉、麻纖維幼稚園服裝面料成分鑒定:棉、麻纖維燃燒時火焰一近,九州体育娱乐app燃燒迅速,火焰呈黃色,發出藍色煙霧。燃燒后,棉花有很少的粉末狀灰分,黑色或灰色,大麻會產生少量的灰分粉末狀灰分。Identificationoffabriccompositionofcottonandhempfiberkindergartenclothing:whencottonandhempfiberburn,theflameisclose,burningquickly,theflameisyellow,emittingbluesmoke.Afterburning,cottonhaslittlepowderash,blackorgray,hempwillproduceasmallamountofashpowderash.毛纖維和真絲毛在火中冒煙,燃燒時起泡,燃燒速度較慢,發出一股焦味頭發燃燒,燃燒后的灰燼多為光滑的黑色球狀顆粒,一壓即斷指。絲遇壓痕使火,燃燒速度減慢,發出嘶嘶聲,散發出燒焦頭發的氣味,形成深褐色的小球后燃燒成灰燼,手捻即斷。Thehairfiberandsilkhairsmokeinthefire.Whenitburns,itbubbles.Theburningspeedisslow.Itgivesoffaburningsmellofhair.Afterburning,theashesaremostlysmoothblacksphericalparticles,andthefingersarebrokenwhenitispressed.Whenthesilkmeetstheindentation,thefireslowsdown,hisses,andgivesoffthesmellofburnthair.Afterformingadarkbrownball,itburnstoashes,andthehandtwistsandbreaks.聚酰胺及聚酯聚酰胺學名聚酰胺纖維,靠近火焰或卷曲熔融成白色膠體,迅速熔滴而閃閃發光,在火焰中燃燒無火,留下火焰燃燒難,散發出芹菜味,米色熔融材料冷卻后不易粉碎。滌綸纖維學名滌綸,易引燃,靠近火焰即收縮、熔化、燃燒時冒煙,火焰呈黃色,氣味芳香,燃燒后灰燼為深褐色塊狀,可用手指捻捻。Polyamideandpolyesterpolyamide,thescientificnameofpolyamidefiber,closetotheflameorcurlandmeltintowhitecolloid,quicklymeltandsparkle,burnintheflamewithoutfire,leavingtheflameburninghard,sendingoutthesmellofcelery,thebeigemeltingmaterialisnoteasytocrushaftercooling.Thescientificnameofpolyesterfiberispolyester,whichiseasytoignite.Itshrinks,meltsandsmokeswhenitisclosetotheflame.Theflameisyellowandsmellsfragrant.Aftercombustion,theashisdarkbrownblock,whichcanbetwistedbyfingers.丙烯和聚丙烯丙烯的學名為聚丙烯腈纖維,靠近火軟化融化后再冒煙,用大火燒成白色火焰,大火迅速燃燒后,散發出火種肉的苦味,燃燒后灰燼為不規則黑色塊狀,手捻易碎。聚丙烯的學名,聚丙烯纖維靠近火焰即收縮,易燃,燃燒緩慢而冒煙,火焰上部呈黃色,底部呈藍色,散發出油煙味,燃燒后的灰燼如堅硬的小黃褐色顆粒,經手捻后易碎。Thescientificnameofpropyleneandpolypropylenepropyleneispolyacrylonitrilefiber.Itsoftensandmeltsnearthefireandthensmokes.Itburnsintoawhiteflamewithalargefire.Afterthefireburnsrapidly,itgivesoffthebittertasteofthefiremeat.Afterthefire,theashesareirregularblackblocks,andthehandsarefragile.Scientificnameofpolypropylene:polypropylenefibershrinkswhenitisclosetotheflame.Itisflammable.Itburnsslowlyandsmokes.Theupperpartoftheflameisyellowandthebottomisblue.Itgivesoffthesmellofoilsmoke.Theashesafterburningarelikesmallhardyellowbrownparticles,whicharefragileafterbeingtwistedbyhand.

學名whalen和氯綸whalen聚乙烯醇甲醛纖維,不容易點燃,近火焰熔融收縮,頂部有少許火焰,燃燒為纖維混合膠化火焰,有濃濃的黑煙,有苦甜的氣味,燃燒后留下黑色小珠顆粒,可用手指壓碎。學名氯綸PVC纖維,不易燃燒,遠離火種即為撲滅,火焰呈黃色,底綠色白色冒煙,辛辣刺激酸澀,燃燒后灰燼為深褐色不規則塊狀,手指扭曲不易折斷。ItsscientificnameisWhalenandchlorofiberWhalenpolyvinylformalfiber,whichisnoteasytoignite.Itisneartheflamemeltingandcontracting.Thereisalittleflameonthetop.Theflameisamixedgelatinizedflameoffiber,withthickblacksmokeandbittersweetsmell.Afterburning,itleavessmallblackbeads,whichcanbecrushedbyfingers.ItsscientificnameisPVCfiber,whichisnoteasytoburn.Ifitisfarawayfromthefire,itwillbeextinguished.Theflameisyellow,withgreenandwhitesmokeatthebottom.Itisspicyandsour.Afterburning,theashisdarkbrownirregularblock,andthefingersarenoteasytobreak.氨綸和氟烷氨綸,又稱聚氨基甲酸酯纖維,在火附近熔化和燃燒,火焰燃燒時呈藍色,離開火繼續熔化和燃燒,發出一種特殊的刺激性氣味,燃燒后的灰燼是柔軟而蓬松的黑色灰燼。Spandexandhalothanespandex,alsoknownaspolyurethanefiber,meltandburnnearthefire.Whentheflameburns,itisblue,andcontinuestomeltandburnawayfromthefire,givingoutaspecialpungentsmell.Theashaftercombustionissoftandfluffyblackash.ISO組織稱其為螢石纖維,靠近火焰處僅熔化,難以點燃,不燃燒,火焰邊緣呈藍綠色碳化,熔化分解,有毒氣體,熔化為堅硬的圓形黑珠。ISOorganizationcallsitfluoritefiber.Itisonlymeltedneartheflame,whichisdifficulttoigniteanddoesnotburn.Theflameedgeisblue-greencarbonization,meltingdecomposition,toxicgas,meltingintoahardroundblackbead.
