dhinaca dharka quruxda tolida functional sida codsiga of spandex knited maryaha

Dharka tolida ee shaqaynaysa ee dharka quruxda leh sida codsiga maro tolida spandex, shaqadeeda ayaa sidoo kale si tartiib tartiib ah loo horumariyay jirka caagga ah, iyada oo loo marayo in lagu dhejiyo dharka tolida spandex, waxay sameyn kartaa nooca jirka ee caagga ah ee dharka tolida, waxayna qaadi kartaa barida, caloosha saameynteeda. , iyo suuqa dharka ee hadda jira qayb weyn oo iib ah. Isla mar ahaantaana, spandex waxay leedahay saameynta difaaca ee thrombus, taas oo sidoo kale ka dhigaysa sharaabaadyo tolidan oo ay ku jiraan spandex caan ah. Waa iyada oo loo marayo hagaajinta gelinta spandex, xoogga ciriiriga laastikada ah ayaa si tartiib tartiib ah kor ugu kacaya dhamaadka sare ee sharabaadyada tolida ilaa dhamaadka hoose, si loo sii wanaajiyo socodka dhiigga lugaha, si loo gaaro saameynta shaqeynta ee ka hortagga thrombus.
Farqiga u dhexeeya halbeegga Yurub EN388 iyo heerka American ANSI/ISEA105

Gacan-gashiyada iska caabbinta leh ee lagu caddeeyey heerka Yurub waxay yeelan doonaan garaaf gaashaamo oo ay ku qoran yihiin "EN 388" Waxaa jira 4 ama 6 nambaro iyo xarfo hoosta garaafiga gaashaanka. Haddii ay tahay 6 nambar iyo xarfo, waxay ka dhigan tahay in EN 388: 2016 ugu dambeeyay la isticmaalo. Haddii ay tahay 4 nambar, waxay la macno tahay inay tahay heerkii hore ee 2003.

↑ Sawirka bidix waa halbeeggii hore, sawirka midigna waa halbeegga cusub.
4ta nambar ee hore waxay leeyihiin macne isku mid ah, kuwaas oo ah "iska caabbinta xidho", "iska caabbinta gooyay", "iska caabbinta ilmada", iyo "iska caabin dalool". Inta uu bato nambarku, ayaa waxqabadku sii fiicnaanayaa. Xarafka shanaad waxa kale oo uu ka dhigan yahay "iska caabbinta gooyey", laakiin habka imtixaanku wuu ka duwan yahay kan lambarka labaad, iyo matalaadda darajada iska caabbinta gooyay ayaa sidoo kale ka duwan, taas oo si faahfaahsan looga hadli doono dambe. Xarafka lixaad waxa uu u taagan yahay "saameyn iska caabin" waxaana sidoo kale lagu matalaa xarfo. Si kastaba ha ahaatee, waxaa jiri doona lambar lixaad haddii tijaabada iska caabinta saameynta la sameeyo. Haddii aan la fulin, waxaa jiri doona kaliya 5 lambar. Inkasta oo nooca 2016 ee heerka Yurub la isticmaalay in ka badan 4 sano, weli waxaa jira noocyo badan oo ka sii weyn oo galoofyada suuqa. Gacan-gashiyada iska caabbinta leh ee ay cadeeyeen heerarkii hore iyo kuwii hore dhamaantood waa gacmo-gashiyo u qalma, laakiin waxaa aad loogu talinayaa in la iibsado galoofyada adkeysi u leh ee isticmaala nambarada 6-god iyo xarfo si ay u muujiyaan waxqabadka galoofyada. Heerka American ANSI 105 muujinta.

Sannadka 2016, halbeegga Mareykanka ANSI 105 ayaa sidoo kale la sameeyay cusbooneysiin. Heerarka iska caabbinta jarista ee asalka ah waxaa lagu matalay 1-5 ee garaafyada gaashaanka, oo hadda waxa ay u taagan tahay “A1″ ilaa “A9″. Sidoo kale, tirada weyn ee tirada, ayaa ka sarreeya heerka iska caabbinta gooyay.

Laakin waa maxay sababta habka kala soocida looga cusboonaysiiyo 5 heer ilaa 9 heerar? Sababta ayaa ah in soo ifbaxa waxyaabo badan oo cusub, kala saarid faahfaahsan ayaa loo baahan yahay si loo muujiyo caabbinta la jaray ee galoofyada. Habka darajooyinka cusub, A1-A3 asal ahaan waa la mid ah 1-3 asalka ah, laakiin marka la barbardhigo 4-5 asalka ah, A4-A9 waxay isticmaashaa 6 darajooyin si ay u qaybiso heerka 2 asalka ah, kaas oo u adkeysan kara galoofyada. Iska yaree jinsiga si aad u muujiso si fiican. Heerka ANSI, cusbooneysiintu maaha kaliya muujinta heerka, laakiin sidoo kale habka tijaabada. Tijaabada asalka ah waxaa loo adeegsaday heerka ASTM F1790-05, kaas oo u oggolaanaya in lagu tijaabiyo mashiinka TDM-100 (habka tijaabada waxaa loo yaqaannaa TDM TEST) ama mashiinka CPPT (qaabka tijaabada waxaa loo yaqaan TEST COUP), hadda heerka ASTM F2992-15 ayaa la isticmaalaa, kaliya TDM ayaa la isticmaalaa. loo oggolaaday TEST inuu tijaabiyo. Waa maxay faraqa u dhexeeya TDM TEST iyo TEST?

TEST TEST waxay isticmaashaa daab wareeg ah oo cadaadis ah 5 Newtons si uu u rogo oo u gooyo shayga galoofyada, halka TDM TEST uu isticmaalo daab si uu ugu cadaadiyo qalabka galoofyada oo leh cadaadisyo kala duwan, isaga oo dib iyo hore u jaraya si toosan xawaare dhan 2.5 mm/s . In kasta oo halbeegga cusub ee Yurub ee EN 388 uu dhigayo in laba hab oo tijaabo ah oo kala ah IMTIXAANKA INQAABKA iyo TDM TEST, la isticmaali karo, iyadoo la raacayo IMTIXAANKA INQAABKA, haddii ay tahay wax-qabad heersare ah oo ka-hortagga wax-goynta, daab-wareegga ayaa laga yaabaa inuu af-beelo. Waxaa la xisaabiyaa in daabku af-furan yahay, TDM TEST waa qasab. Waa in la ogaadaa in haddii gacma-gashiga ka-hortagga-goynta ee waxqabadka sare uu maray TDM TEST, "X" ayaa lagu qori karaa nambarka labaad ee garaafka shahaadada. Waqtigan xaadirka ah, iska caabbinta gooyay ayaa kaliya lagu matalay xarafka shanaad. Haddii aanay ahayn gacan-gashi-gacan-gashi aad u sarreeya oo adkaysi u leh, uma badna in shayga gacan-gashigu uu daciifiyo daabka IMTIXAANKA INGAANKA. Waqtigaan, TDM TEST waa la dhaafi karaa. Lambarka shanaad ee qaabka shahaado bixinta waxa lagu muujiyay "X".
