Pigment kudhinda vs dhayi kudhinda

Kudhinda

Iko kunonzi kudhinda ndiyo nzira yekugadzirisa yekugadzira dhayi kana pendi mumucheka wemavara, munzvimbo ino kuishandisa kune machira uye kudhinda mapatani. Kuti upedze kudhinda kwemucheka, nzira yekugadzira inoshandiswa inonzi kudhinda maitiro.

Pigment Printing

Pigment printing inzira yekudhinda iyo pigment inonamirwa pamucheka nenzira ye high molecular polymer (adhesive) uye mvura-insoluble colored substances (pigments) kuti iite firimu rakasimba, rakajeka uye risingapfeki pamucheka.

Kudhinda dhayi

Panyaya yemagadzirirwo edhayi dhayi fiber, kudhinda uye dhayi zvakafanana, kunze kwekuti mukudhinda, dhayi yeimwe ruvara inoshandiswa munharaunda kune machira maererano nezvinodiwa zvepateni, uye mushure meimwe kurapwa, dhayi. dhayi iyo fiber, uye ipapo zvigadzirwa zvakadhindwa zvine rumwe kana akawanda mavara zvinowanikwa pamucheka. Naizvozvo, kudhinda kunogona zvakare kunzi "kudhaya kwenzvimbo".

Coloring musimboti pendi

Pigment printing inzira yekudhinda inomisa kunamatira kubva pakugadzira firimu rakasimba, rakajeka uye rinopfeka-kusapfeka pamucheka, kuitira kuti igadzirise pende pamucheka.

Coloring zvinhu zvedhayi

Kudhaya inzira yekugadzirisa umo machira anowana mavara akajeka uye akasimba kuburikidza nemuviri, makemikari kana emuviri-kemikari musanganiswa wedhayi (kana pigment) uye machira.

Zvakanakira nezvayakaipira

Pigment Printing

Zvakanakira:

•Kushandiswa kwakapusa, maitiro akareruka, kugadzirwa kwakanyanya kwevashandi, kunogona kuderedza kubuda kwetsvina

•Yakafara chromatogram, yakakwirira kusimba, yakajeka kudhinda mitsetse uye contours

•Inokodzera nzira dzakakosha dzekudhinda, uye inogona zvakare kushandiswa kuburitsa uye anti dyeing kudhinda

•Kuenzanisa kwemavara kuri nyore uye kunaka kwemavara mwenje kubereka

•Inokodzera kudhindwa kwejira rezvinhu zvakasiyana-siyana zvefiber, kunyanya machira akasanganiswa.

Zvakaipa:

• Kusanzwa zvakanaka kwemaoko, kusaoma uye kunyorova nekukwesha

• Kushandiswa kweparafini mu emulsified paste kunosvibisa mweya; Mazhinji emamonomers anoshandiswa kugadzira zvinonamira ane chepfu

• Kupenya kwemavara hakuna kujeka seyekudhinda dhayi nechimiro chakaenzana

• Iyo yakanamatira iri nyore kusvuura uye kuvhara mesh

Kudhinda dhayi (kutora madhayi anoshanda semuenzaniso)

Zvakanakira:

• Kune marudzi akawanda, machromatograms akazara uye mavara akajeka

• Zviri nyore kugadzirira paste yemavara, nyore kudhinda maitiro, maitiro akanaka uye mashoma mashoma

• Kutsanya kwakanaka kwekunyorova kurapwa

• Mutengo wakaderera wokudhinda uye kuwirirana kwemavara kuri nyore

Zvakaipa:

• Vazhinji vavo havagoni kupikisa chlorine, uye chiyero chekugadzirisa chakaderera. Mamwe madhayi anochinja ane kunanga kukuru (affinity), izvo zviri nyore kukonzeresa kusvibiswa kana sipo, kunyanya kana ichidhinda yakadzika uye yakakora mavara.

Musiyano:

Musiyano mukuru pakati pekudhinda dhayi uye kudhinda kwe pigment ndeyekuti kudhinda kwe pigment kunosanganiswa nemucheka nekubatana kwenyama, nepo kudhinda kwedhayi kunosanganiswa zvakananga nemucheka nevan der Waals force.

Pigment kudhinda inogona kushandiswa kugadzirisa chero machira efiber. Iine zvimwe zvakanakira kudhindwa kwemisanganiswa uye machira akarukwa. Iine maitiro akareruka, yakafara chromatography, yakajeka ruva chimiro chechimiro, asi kushata kweruoko kunzwa uye kuderera kwekukwesha kukurumidza. Kutsanya kwavo kwakareruka uye kuoma kwekuchenesa nekukurumidza kwakanaka, kunyange kwakanakisa, saka ivo vanoshandiswa zvakanyanya mumachira ekushongedza, machira emaketeni uye machira ekupfeka anoda kucheneswa kwakaoma.

Nzira yekusiyanisa pakati pekudhinda dhayi uye pigment kudhinda

Pigment kudhinda uye dhayi kudhinda kunogona kusiyaniswa nekuenzanisa kuomarara musiyano pakati pechikamu chakadhindwa uye chikamu chisina kudhindwa chejira rimwe chete. Ruoko runonzwa rwepende yakadhindwa nzvimbo yakaoma zvishoma kudarika iyo yenzvimbo isina kudhindwa, iyo inogona kunge yakanyanyisa. Kana jira rakadhindwa nedhayi, hapana mutsauko wakajeka wekuoma pakati pechikamu chakadhindwa uye chikamu chisina kudhindwa.
