Kugadzika Kwekupisa Kwekupedzisira Kwekugadzikana Kwedhayi

Kugadziriswa kwekupisa kwekupedzisira kunobatsira zvikuru pakushambidzwa kwese uye kusimba kwezvipfeko zvemitambo zvakagadzirwa nedhayi. Chishandiso chekupisa chinoita basa rakakosha mukuita kwekudhinda kwe sublimation. Inoita kuti inki ye sublimation ipinde mufiber yechinhu chacho. Izvi zvinoita kuti pave nemaprints asingangove anopenya chete asiwo anogara kwenguva refu. Inki inova chikamu chesubstrate pachayo. Kusiyana nenzira dzechinyakare apo inki inogara pamusoro pechinhu chacho, sublimation inoisa dhizaini mukati mefibers, zvichiwedzera kugara kwenguva refu uye kutaridzika zvakanaka.

Maitiro acho anosanganisira matanho akakosha akati wandei:

1. Kupararira kweDyi: Inki dzesublimation dzine madhayi akapararira. 380–400°F (193–204°C) kupisa, madhayi aya anoshanduka kubva pakuva akaoma kuita gasi.
2. Kuvhurwa kwePolymer: Pakupisa kwakanyanya, cheni dzepolymer dzepolyester dzinosunungura. Izvi zvinobvumira mamorekuru edhayi ane gasi kupinda mufayibha.
3. Kutonhodza & Kukiya: Sezvo jira richitonhora, cheni dzepolymer dzinovharana, dzichivhara mamorekuru edhayi mukati mechivako. Izvi zvinoguma nekusungana kusingaperi kusingawachi, kukweshwa, uye kusvibiswa neUV.

Mhando dzakasiyana dzemachira dzinoda mamiriro chaiwo ekupisa kuti dzikwanise kuchengetedza ruvara rwakanaka:

Rudzi rweMachira	Tembiricha (°F)	Nguva Yokugara (Masekonzi)	Dhigirii reDzvinyiriro	Kuchengetedza Ruvara Mushure mekugezwa (%)
100% Polyester	380–400	45–60	Pakati nepakati (≈40 psi)	90–95%
65/35 Poly-Donje	375–385	50–60	Pakati nepakati (≈40 psi)	70–75%
50/50 Poly-Donje	370–380	60–70	Pakati Nepakati-Pamusoro (≈50 psi)	50–55%
100% Donje + Kuputira	360–375	60–75	Pakati Nepakati-Pamusoro (≈50 psi)	65–70%

Semuenzaniso, mashati epolyester aipiswa pa390°F kwemasekonzi makumi mashanu airamba aine resolution ye90% uye achipenya mushure mekusukwa ka25. Mashati edonje asina kugadziriswa, achishandisa magadzirirwo akafanana, aingowana ruvara rwe30% chete uye aipera simba mushure mekusukwa ka10 chete. Donje rine poly coating rakawedzera kusvika pa65–70%, asi izvi zvakawedzera mari yekuwedzera ye20% payuniti imwe neimwe.
