Kev zas xim rau cov ris tsho jeans feem ntau siv cov xim indigo, cov xim sulfur thiab cov xim reactive. Ntawm lawv, cov xim indigo yog txoj kev zas xim denim feem ntau, muab faib ua cov xim indigo ntuj thiab cov xim indigo tsim. Cov xim indigo ntuj yog rho tawm los ntawm cov nyom indigo thiab lwm yam nroj tsuag, thaum cov xim indigo tsim yog ua los ntawm cov khoom lag luam petrochemical xws li aniline thiab lwm yam khoom siv raw.
Ntxiv rau kev zas xim indigo, kev zas xim sulfur kuj yog ib qho ntawm cov txheej txheem zas xim rau cov ris tsho jeans. Txoj kev zas xim no siv cov xim vulcanized los zas xim cov ntaub tsaus nti, uas muaj cov yam ntxwv ntawm kev ntxuav thiab hnav-resistant. Piv nrog rau kev zas xim indigo, cov xim zas xim sulfur ci dua, tsim nyog rau kev tsim ntau yam xim ntawm cov ris tsho jeans.
Cov xim vulcanized, feem ntau yog siv rau kev zas xim paj rwb, kuj tseem siv tau rau cov ntaub paj rwb/vitamin sib xyaw. Cov xim sulfur tsis muaj cov pab pawg yaj hauv dej hauv lawv cov qauv molecular, yog li lawv tsis tuaj yeem yaj ncaj qha rau hauv dej. Txawm li cas los xij, thaum ntxiv cov neeg sawv cev txo qis xws li alkali sulfur, disulphur bond, sulfoxyl pawg, thiab quinone pawg hauv cov xim sulfur raug txo kom sulfhydryl pawg, uas yog, leucosome, thiab cov xim tuaj yeem yaj hauv dej lub sijhawm no.
Qhov zoo tshaj plaws ntawm cov xim vulcanized suav nrog tus nqi qis, thiab cov xim feem ntau ntxuav tau thiab ceev. Tsis tas li ntawd, kev siv cov xim vulcanized kuj yooj yim heev, tsuas yog tom qab cov xim yaj lawm thiaj li tuaj yeem zas xim tau. Txawm li cas los xij, cov xim ntawm cov xim sulfur tsis tiav, cov xim tsis ci txaus, feem ntau yog dub, xim av, xiav thiab lwm yam. Txawm hais tias qhov xim ceev ceev rau kev ntxuav yog siab, qhov ceev ceev rau kev dawb yog qis, thiab nws yooj yim rau brittle thaum khaws cia.
Peb lub tuam txhab feem ntau tsim tawmSulfur Dub 240%, kua sulfur dub, Xiav Sulphur 7. Kev xa tawm mus rau Bangladesh, Is Nrias teb, Pakistan, Egypt, thiab Iran txhua xyoo. Ob qho tib si kev muab khoom thiab qhov zoo yog qhov ruaj khov tshwj xeeb. Qhov tseem ceeb tshaj plaws yog qhov zoo dua ntawm tus nqi.
