dziwitsani:
Ma sutures opangira opaleshoni ndi zigawo zake ndi zida zofunika kwambiri pazachipatala ndi opaleshoni. Amagwira ntchito yofunika kwambiri potseka chilonda, kulimbikitsa machiritso ndi kuchepetsa chiopsezo cha matenda. Mu positi iyi yabulogu, tikambirana za kufunikira kwa ma sutures osabala, makamaka ma suture omwe sangatengeke opangidwa ndi nayiloni kapena polyamide. Tidzafufuzanso mitundu yosiyanasiyana ya ma polyamides ndikugwiritsa ntchito kwawo mu ulusi wa mafakitale. Kumvetsetsa kapangidwe ndi ubwino wa zipangizozi kudzatithandiza kumvetsa kufunika kwawo pa opaleshoni.

Chemistry kumbuyo kwa polyamide 6 ndi polyamide 6.6:
Polyamide, yomwe imadziwika kuti nayiloni, ndi polima wopangidwa mosiyanasiyana. Pakati pa mitundu yake yosiyanasiyana, polyamide 6 ndi polyamide 6.6 ndizofunika kwambiri. Polyamide 6 imakhala ndi monoma imodzi yokhala ndi maatomu asanu ndi limodzi a carbon, pamene polyamide 6.6 ndi kuphatikiza ma monoma awiri okhala ndi maatomu asanu ndi limodzi a carbon. Kupanga kwapadera kumeneku kumatchedwa 6.6, kutsindika kukhalapo kwa ma monomer awiri.

Ma sutures osabala osayamwa:
Ma suture osabala omwe sangatengeke nthawi zambiri amagwiritsidwa ntchito popanga opaleshoni pomwe suture iyenera kukhalabe m'thupi kwa nthawi yayitali. Ulusiwu umapangidwa kuchokera ku zinthu monga nayiloni kapena polyamide, kuonetsetsa kulimba ndi mphamvu. Mosiyana ndi ma sutures otsekemera, omwe amasungunuka pakapita nthawi, ma sutures osasunthika amapangidwa kuti akhale okhazikika, opereka kutseka kwa mabala kwa nthawi yayitali.
Ubwino wa sutures wosabala:
1. Mphamvu ndi kulimba: Ma sutures a nayiloni ndi polyamide ali ndi mphamvu zolimba kwambiri ndipo amatha kupirira kupsinjika komwe kumabwera chifukwa cha kutsekedwa kwa bala ndi kusuntha kwa minofu.

2. Kuchepetsa chiopsezo cha matenda: Chikhalidwe chosayamwa cha ma sutures amachepetsa chiopsezo cha matenda chifukwa amatha kuzindikirika ndikuchotsedwa ngati kuli kofunikira.

3. Kuchiritsa mabala: Zovala zosabala zimathandizira kulumikiza m'mphepete mwa zilonda, kuchiritsa bwino komanso kuchepetsa mabala.

Kugwiritsa ntchito ulusi wa mafakitale mu sutures opaleshoni:
Popeza polyamide 6 ndi 6.6 amagwiritsidwa ntchito kwambiri mu ulusi wa mafakitale, katundu wawo amawapangitsanso kukhala oyenera ma sutures opangira opaleshoni. Mphamvu zachilengedwe komanso kukana kwa abrasion kumasulira kukhala kutsekedwa kodalirika komanso kotetezeka kwa bala. Kuphatikiza apo, kusinthasintha kwa polyamide kumapangitsa kuti ma sutures agwirizane ndi zofunikira za opaleshoni.

Pomaliza:
Ma sutures opangira opaleshoni ndi zigawo zake, makamaka ma sutures osabala osayamwa opangidwa ndi nayiloni kapena polyamide, amagwira ntchito yofunika kwambiri pakutseka kwa bala. Kumvetsetsa chemistry kumbuyo kwa polyamide 6 ndi polyamide 6.6 kumapereka chidziwitso pazida zomwe zimagwiritsidwa ntchito komanso mawonekedwe ake apadera. Pogwiritsa ntchito ma sutures okhalitsa komanso okhalitsa, akatswiri azachipatala amatha kuonetsetsa kuti mabala atsekedwa bwino komanso zotsatira zabwino za odwala.
