Tsawon hasken rana: yana nufin iyawar kayan rini don kula da asalin launinsu a ƙarƙashin hasken rana. Bisa ga ƙa'idodi na gaba ɗaya, ma'aunin saurin rana yana dogara ne akan hasken rana a matsayin ma'auni. Don sauƙaƙe sarrafawa a cikin dakin gwaje-gwaje, ana amfani da hanyoyin hasken wucin gadi gabaɗaya kuma ana gyara su idan ya cancanta. Mafi yawan amfani da tushen hasken wucin gadi shine hasken hernia, amma kuma ana amfani da fitilun arc na carbon. Ƙarƙashin hasken haske, rini yana ɗaukar makamashi mai haske, matakin makamashi yana ƙaruwa, kuma kwayoyin suna cikin yanayi mai ban sha'awa. Tsarin launi na kwayoyin rini yana canzawa ko kuma ya lalace, yana sa rini ya lalace kuma ya haifar da canza launi ko dushewa.
1. Tasirin haske akan rini
Lokacin da kwayoyin rini ya sha ƙarfin photon, zai sa electrons na waje na valence na kwayoyin su canza daga yanayin ƙasa zuwa yanayin farin ciki.
Abubuwan halayen hoto suna faruwa a tsakanin ƙwayoyin rini masu daɗi da sauran ƙwayoyin cuta, wanda ke haifar da ɗaukar hoto na rini da photobrittleness na fiber.
2.Abubuwan da ke shafar saurin haske na dyes
1). Madogarar haske da tsawon tsayin haske mai haskakawa;
2). Abubuwan muhalli;
3). Abubuwan sinadaran da tsarin tsari na zaruruwa;
4). Ƙarfin haɗin kai tsakanin rini da fiber;

3.Hanyoyin inganta saurin hasken rana na rini
1). Inganta tsarin rini don ya iya cinye makamashi mai haske yayin da yake rage tasiri akan tsarin launi mai launi, don haka kiyaye launi na asali; wato, ana yawan faɗin rini masu saurin haske. Farashin irin waɗannan rini gabaɗaya ya fi na rini na yau da kullun. Don yadudduka tare da buƙatun faɗuwar rana, yakamata ku fara farawa da zaɓin rini.
2). Idan an yi rina masana'anta kuma saurin haske bai cika buƙatun ba, ana iya inganta shi ta amfani da ƙari. Ƙara abubuwan da suka dace a lokacin aikin rini ko bayan rini, ta yadda idan hasken ya bayyana, zai amsa da haske kafin rini kuma ya cinye makamashin haske, ta haka ne ya kare kwayoyin rini. Gabaɗaya ya kasu kashi ultraviolet absorbers da anti-ultraviolet jamiái, tare da ake magana a kai a matsayin rana azumi enhancers.
Ƙunƙarar hasken rana na yadudduka masu haske waɗanda aka rina tare da rini masu amsawa
Fadewar haske na rini masu amsawa wani hadadden dauki ne na photooxychlorination. Bayan fahimtar tsarin na'urar daukar hoto, muna iya ƙirƙira wasu cikas ga ɗaukar hoto yayin zayyana tsarin kwayar halitta na rini don jinkirta faɗuwar haske. Misali, rini mai launin rawaya da ke dauke da kungiyoyin dolsulfonic acid da pyrazolone, rinayen shudi mai dauke da zoben methyl phthalocyanine da disazo trichelate, da rinayen jajayen rini masu dauke da rukunonin karfe, amma har yanzu ba su da jajayen juriyar hasken rana. Rini mai amsawa don saurin haske.
Sautin haske na kayan rini ya bambanta tare da canjin maida hankali ga rini. Don yadudduka da aka rina tare da rini iri ɗaya akan fiber iri ɗaya, saurin haske yana ƙaruwa tare da haɓaka haɓakar rini. Matsakaicin rini na yadudduka masu launin haske yana da ƙasa kuma saurin haske yana da ƙasa. digiri ya ragu daidai. Koyaya, saurin haske na rini na gama-gari akan katin launi na buga ana auna lokacin da yawan rini ya kasance 1/1 na daidaitaccen zurfin (watau 1% owf ko 20-30g/l). Idan ƙaddamarwar rini shine 1/6. A cikin yanayin 1/12 ko 1/25, saurin haske zai ragu sosai.
Wasu mutane sun ba da shawarar yin amfani da abubuwan sha na ultraviolet don inganta saurin hasken rana. Wannan hanya ce da ba a so. Ana amfani da haskoki na ultraviolet da yawa, kuma ana iya inganta shi kawai da rabin mataki, kuma farashin ya fi girma. Sabili da haka, kawai zaɓi mai dacewa na dyes zai iya magance matsalar saurin haske.
