Gawoli limathandiza kuchotsa utoto wosakhazikika komanso wosakhazikika.
4. Kutsuka Madzi Ozizira: Tsukani ndi madzi ozizira mukatha kutsuka ndi madzi otentha.
5. Bwerezani ngati pakufunika: Bwerezani njira yotsukira ngati pakufunika mpaka utoto wonse utatha ndipo njira yotsukira/kutsuka ikhale yoyera.

Kutentha Komaliza Kuti Utoto Ukhale Wolimba

Kukhazikitsa kutentha komaliza kumathandizira kwambiri kuti zovala zamasewera zopangidwa ndi utoto zisamasuke komanso kuti zisawonongeke. Chosindikizira chotenthetsera chimagwira ntchito yofunika kwambiri mu njira yosindikizira ya sublimation. Zimaonetsetsa kuti inki ya sublimation imalowa mu ulusi wa chinthucho. Izi zimapangitsa kuti pakhale zosindikizira zomwe sizimangokhala zowala komanso zolimba kwambiri. Inkiyo imakhala gawo la substrate yokha. Mosiyana ndi njira zachikhalidwe zomwe inki imakhala pamwamba pa chinthucho, sublimation imayika kapangidwe kake mkati mwa ulusiwo, zomwe zimawonjezera kulimba komanso kukongola.

Njirayi ikuphatikizapo masitepe angapo ofunikira:

1. Kufalikira kwa Utoto: Inki za sublimation zili ndi utoto wosakanikirana. 380–400°F (193–204°C) kutentha, utoto uwu umasanduka kuchokera ku cholimba kukhala mpweya.
2. Kutsegula kwa polima: Pa kutentha kwambiri, unyolo wa polima wa polyester umamasuka. Izi zimathandiza kuti mamolekyu a utoto wa gasi alowe mu ulusi.
3. Kuziziritsa & Kutseka: Nsalu ikazizira, maunyolo a polima amatseka, ndikutseka mamolekyu a utoto mkati mwa kapangidwe kake. Zotsatira zake zimakhala mgwirizano wokhazikika wosagwirizana ndi kusamba, kukwawa, komanso kuwonekera pa UV.

Mitundu yosiyanasiyana ya nsalu imafuna mikhalidwe yapadera yokonzera kutentha kuti isunge utoto bwino:

Mtundu wa Nsalu	Kutentha (°F)	Nthawi Yokhala (Masekondi)	Mulingo Wopanikizika	Kusunga Utoto Pambuyo Potsuka (%)
100% Polyester	380–400	45–60	Pakati (≈40 psi)	90–95%
65/35 Poly-Thonje	375–385	50–60	Pakati (≈40 psi)	70–75%
50/50 Poly-Thonje	370–380	60–70	Pakati-Pamwamba (≈50 psi)	50–55%
100% Thonje + Chophimba	360–375	60–75	Pakati-Pamwamba (≈50 psi)	65–70%

Mwachitsanzo, malaya a polyester omwe amatenthedwa pa 390°F kwa masekondi 50 amakhalabe ndi mphamvu komanso kulimba pafupifupi 90% atatsukidwa kasanu ndi kamodzi. Malaya a thonje omwe sanatsukidwe, pogwiritsa ntchito njira zomwezo, adapeza mtundu wochepa wa 30% ndipo amafota kwambiri atatsukidwa kasanu ndi kamodzi kokha. Thonje lokhala ndi polyester linakhala lolimba mpaka 65–70%, koma izi zinawonjezera ndalama zowonjezera pafupifupi 20% pa unit iliyonse.
