Uburyo bwo gukora nibiranga indigo ubururu

Ikoreshwa ryirangi rya indigo rifite amateka yimyaka irenga 5000 kandi rifatwa nkirangi rya kera. Uruganda rwacu ubu rukoresha ibikoresho bigezweho hamwe nikoranabuhanga ribyara umusaruro kugirango ubyare ubururu bwa indigo, kugirango tumenye neza ko ibicuruzwa byubururu bwa indigo bifite ubuziranenge bwiza , kandi itara ryamabara ryujuje ibyangombwa byimyambarire mpuzamahanga yimyenda na jeans, hagamijwe kugera kurwego mpuzamahanga, gukora jeans kurushaho kuba indashyikirwa, no gukora imyenda yimyambarire ikunzwe cyane.
(1) Uburyo bwo gukora
Sodium ya Metal ikorana numunyu wa potasiyumu hamwe namazi ya soda ya caustic kugirango itange indoxyl, amazi yifata numwuka kugirango itange ubururu bwa indigo, hanyuma ikabiyuhagira muri cake iyungurura ikoresheje isahani hamwe na kadamu, hanyuma igahindura ibishishwa ikoresheje umunara wa spray hamwe ninyongera.
(2) Gukemura
Gushonga buhoro mumazi, Ethanol, glycerine na propylene glycol, kutaboneka mumavuta namavuta.0.05% igisubizo cyamazi cyari ubururu bwijimye.1g irashonga hafi 100ml, amazi kuri 25 ° C, gukomera mumazi biri munsi yizindi pigment ya syntetique iribwa, kandi igisubizo cyamazi 0.05% nubururu.Gushonga muri glycerine, propylene glycol, gushonga gake muri Ethanol, kudashonga mumavuta.Iyo acide sulfurike yibanze, ni ubururu bwijimye, kandi nyuma yo kuyungurura, ni ubururu.Igisubizo cyamazi wongeyeho sodium hydroxide nicyatsi kibisi cyumuhondo.Indigo iroroshye kurangi, ifite amajwi yihariye, kandi ikoreshwa cyane.Kurwanya ubushyuhe, kurwanya urumuri, kurwanya alkali, kurwanya okiside, kwihanganira umunyu no kurwanya bagiteri byombi ni bibi.Kugabanuka iyo kugabanya, nko kugabanuka hamwe na sodium sulfoxylate cyangwa glucose, ihinduka umweru.Uburebure ntarengwa bwo kwinjiza ni 610 nm ± 2 nm.
(3) Gusaba
Ikoreshwa cyane cyane mu gusiga fibre ya pamba .Imyenda ya pop "cowboy" ahanini ikorwa nubururu bwa indigo ubururu bupfa uburebure bwigihe kirekire hamwe nudodo twera; , zikoreshwa neza mubintu bisiga amabara, ibinyabuzima nibindi.
