Nigute Wokwirinda Amazi Yumukara Amasoko ya Pamba?

irangi rya sulfuru rikoreshwa cyane cyane mu gusiga irangi rya pamba, ndetse no kumyenda ivanze na pamba / vinylon. Yashongeshejwe muri sodium sulfide kandi ni amahitamo meza kubicuruzwa byijimye bya fibre selile, cyane cyane kuri Sukure yumukara 240% na Sulfuru Ubururu 7dyeing. Umubyeyi wamabara ya sulfuru ntaho ahuriye na fibre, kandi imiterere yayo irimo imigozi ya sulfuru (-S-), disulfide (-SS) cyangwa imigozi ya polysulfide (-Sx-), igabanywa mumatsinda ya sulfhydryl (-SNa) munsi ya ibikorwa bya sodium sulfide reductant.Bahinduka umunyu wa sodium ya elegitoronike. Leuco ifitanye isano ya fibre selile kubera molekile nini y'amabara, itanga Van der Waals nini hamwe na hydrogène ihuza fibre. Nubwo ibara ryerekana amabara ya sulfuru atuzuye, cyane cyane ubururu n'umukara, ibara ntirimurika, ariko kuyikora biroroshye, igiciro ni gito, inzira yo gusiga iroroshye, guhuza amabara biroroshye, kandi kwihuta kwamabara nibyiza .Bikwiye kumenyekana ariko ko amarangi amwe n'amwe ya sulfuru, nk'umukara wa sulfure, ashobora gutera isoko rya Pamba.

Isoko rya fibre rigomba kwitabwaho nyuma yaAmazi yumukara 240%irangi rikoreshwa mu gusiga irangi. Impamvu zimwe zishobora kongera ibyago byo guhindagurika kwa fibre, nko gukoresha amarangi menshi, ntabwo byongera amahirwe yo gukomera gusa, ahubwo binagabanya umuvuduko wamabara kandi bigatuma gukaraba bigorana. Byongeye kandi, nyuma yo gusiga irangi, bigomba gukaraba neza kugirango birinde gukaraba bidahumanye, kandi ibara rireremba kurudodo biroroshye kubora muri acide sulfurike mugihe cyo kubika, bigatuma fibre icika.

Kugabanya cyangwa gukumira isoko rya fibre, ingamba zikurikira zirashobora gufatwa:

1.

2. Nyuma yo gusiga irangi, oza neza n'amazi kugirango wirinde ibara rireremba kubora muri acide sulfure mugihe cyo kubika.

3. Koresha imiti igabanya ubukana, nka urea, ivu rya soda, sodium acetate, nibindi.

4.

5. Kuma umugozi wanditseho irangi mugihe kugirango wirinde gushyushya ubudodo butose mugikorwa cyo guteranya, bigatuma igabanuka ryibintu birwanya ubukana nagaciro ka pH.
