inoshanda knitting runako rwechipfeko chimiro sekushandiswa kwespandex yakarukwa machira

inoshanda yakarukwa runako rwekupfeka chimiro sekushandiswa kwe spandex yakarukwa machira, basa rayo rakagadzirwawo zvishoma nezvishoma muviri wepurasitiki, kuburikidza nekumisikidza iyo spandex yakarukwa jira, inogona kugadzira epurasitiki muviri rudzi rwembatya dzakarukwa, uye inogona kunge yakatakura buttock, dumbu riri kushanda. , uye pamusika wezvino wembatya unotora chikamu chikuru chekutengesa. Panguva imwecheteyo, spandex ine inodzivirira mhedzisiro ye thrombus, iyo inoita zvakare akarukwa masokisi ane spandex akakurumbira. Iko kuburikidza nekugadziriswa kwe spandex kupinza, iyo elastic compression simba inowedzera zvishoma nezvishoma kubva kumucheto wepamusoro wemasokisi akarukwa kusvika kumucheto wakadzika, kuitira kuti uwedzere kuvandudza kuyerera kweropa, kuitira kuti uwane kushanda kwekudzivirira thrombus.
Musiyano uripo pakati peEuropean standard EN388 neAmerican standard ANSI/ISEA105
Mune aya maviri zviyero, kutaura kweyero yekucheka kuramba kwakasiyana.

Iwo magurovhosi anodzivirirwa akasimbiswa neEuropean standard achave neshield graphic ine mazwi "EN 388" pairi. Kune 4 kana 6 manhamba uye mavara pasi peshield graphic. Kana iri manhamba matanhatu nemabhii, zvinoreva kuti yazvino EN 388:2016 standard inoshandiswa. Kana iri manhamba mana, zvinoreva kuti ndiyo yekare 2003 standard.

↑ Mufananidzo uri kuruboshwe ndiwo chiyero chekare, uye mufananidzo uri kurudyi ndiwo mutsva.
Mavara mana ekutanga ane chirevo chimwe chete, chinoti “wear resistance”, “cut resistance”, “tear resistance”, uye “puncture resistance”. Iyo yakakura nhamba, zviri nani kuita. Tsamba yechishanu inorevawo "kucheka kupikisa", asi nzira yekuedza yakasiyana neyechipiri chechipiri, uye iyo inomiririra yekucheka kupikisa giredhi yakasiyanawo, iyo ichakurukurwa zvakadzama gare gare. Vara rechitanhatu rinomirira "impact resistance" uye rinomiririrwawo nemabhii. Nekudaro, pachave nedhijiti yechitanhatu chete kana bvunzo yekupikisa ikaitwa. Kana ikasaitwa, pachava nenhamba 5 chete. Kunyangwe iyo 2016 vhezheni yeEuropean standard yakashandiswa kweanopfuura makore 4, kuchine akawanda ekare mavhezheni egurovhosi pamusika. Magurovhosi akachekwa anosimirirwa nemaitiro matsva uye ekare ese ari magirovhosi akakodzera, asi zvinokurudzirwa kutenga magurovhosi anodzikiswa anoshandisa manhamba matanhatu nemabhii kuratidza mashandiro egirovhosi. American standard ANSI 105 kutaura.

Muna 2016, iyo American standard ANSI 105 yakagadziridzwa zvakare. Iyo yekutanga yekucheka nhanho yekupikisa yakamiririrwa ne1-5 mune shield graphic, uye ikozvino inomiririrwa ne "A1" ku "A9". Saizvozvowo, iyo yakakura nhamba, iyo yakakwirira yezinga rekucheka kushorwa.

Asi nei kugadzirisa nzira yekuisa kubva pa5 mazinga kusvika pa9 mazinga? Chikonzero ndechekuti nekubuda kwezvimwe zvinhu zvitsva, kutsanangurwa kwakadzama kunodiwa kuratidza kuchekwa kwegorovhosi. Munzira itsva yegiredhi, A1-A3 yakangofanana neyekutanga 1-3, asi ichienzaniswa neyekutanga 4-5, A4-A9 inoshandisa 6 mamakisi kupatsanura iyo yekutanga giredhi renji, inogona kushingirira kumagirovhosi. Cheka bonde kuti utaure zvakanaka. Mune ANSI chiyero, iyo yekuvandudza haisi iyo chete kutaura kweyero, asiwo nzira yekuyedza. Yekutanga bvunzo yakashandiswa ASTM F1790-05 chiyero, iyo inobvumira kuyedzwa pamushini TDM-100 (yebvunzo nzira inonzi TDM TEST) kana CPPT muchina (test nzira inonzi COUP TEST), ikozvino ASTM F2992-15 standard ndiyo inoshandiswa, chete TDM ndiyo iri yakabvumira TEST kuti iedze. Ndeupi musiyano uripo pakati peTDM TEST neCOUP TEST?

COUP TEST inoshandisa denderedzwa blade ine dzvinyiriro ye5 Newtons kukunguruka uye kucheka pane zvinhu zvegirovhosi, nepo TDM TEST inoshandisa blade kudzvanya pane zvinhu zvegirovhosi nezvinomanikidza zvakasiyana, kucheka nekudzoka zvakachinjika nekumhanya kwe2.5 mm/s. . Kunyangwe iyo chiyero chitsva cheEuropean EN 388 ichiti nzira mbiri dzekuyedza, COUP TEST uye TDM TEST, inogona kushandiswa, pasi peCOUP TEST, kana iri yepamusoro-inoshanda anti-kucheka zvinhu, blade inotenderera inogona kugomara. Inoverengerwa kuti blade inova yakagomara, uye TDM TEST inosungirwa. Izvo zvinofanirwa kucherechedzwa kuti kana iyi yepamusoro-inoshanda anti-kucheka girovhosi yakapfuura TDM TEST, "X" inogona kunyorwa pane yechipiri digit ye ​​certification graphic. Panguva ino, kushorwa kwekucheka kunongomiririrwa netsamba yechishanu. Kana isiri girovhosi yepamusoro-soro, hazviite kuti zvinhu zvegirovhosi zvigomedze COUP TEST blade. Panguva ino, TDM TEST inogona kusiiwa. Nhamba yechishanu yepati yetifiketi inoratidzwa ne "X".

↑ Isiri-yepamusoro-inoshanda anti-kucheka magirovhosi, hapana TDM TEST, uye hapana kukanganisa kuramba bvunzo.

↑ Yepamusoro-inoshanda yekucheka-inodzivirira girovhosi zvinhu, TDM TEST yaitwa, COUP TEST uye maitiro ekupikisa bvunzo hazvina kuitwa.

Kunyorerana pakati peAmerican neEuropean zviyero.

American standard A1-A3 neEuropean standard AC ndeyeyero yakaderera yekudzivirira nhanho, American standard A4-A5 uye European standard E ndeyepakati yekucheka giredhi rekudzivirira, American standard A6-A9 uye European standard F ndeyepamusoro kucheka giredhi rekudzivirira.
