Chii chinonzi Reactive Dyes?
Dhayi/Dyestuff ndechimwe chezvinhu zvakakosha muindasitiri yemachira nemamwe maindasitiri.Ikomboni inogona kubatanidza kune chero jira kuti rive nemavara ejira.Kune madhayi akasiyana-siyana pamusika kusarudza kubva, asi anonyanya kufarirwa ndeaya madhayi akagadzikana ane kemikari anogona kupenda jira munguva pfupi.Izvo zviviri zvakakosha zvinhu izvo zvine hunhu reactive dhayi tembiricha uye nguva.
Kushandiswa kwedhayi chiratidzo chakakosha chekunzwisisa kuvandudzwa kwehupfumi hwevanhu.Muhupfumi huri kusimukira hwakaita seIndia neChina, kushandiswa kwedhayi kuri kukura nekukurumidza nekuda kwekuwedzera kwebasa rebudiriro, kukura kwemaguta, uye kuwanda kwevanhu.
Nekuda kwekugona kusiyanisa kwakabva dhayi uye mashandisirwo ayo, kune marudzi mazhinji edhayi.Dhayi dzinowanikwa kubva mumisikirwo dzakadai semiti kana maruva dzinonzi madhayi echisikigo, kwete madhayi ekugadzira.Saizvozvowo, kune madhayi anogona kusiyaniswa maererano nekushandiswa kwawo.Imwe yeanonyanya kushandiswa akasiyana zvichienderana nekushandisa kwavo ndeye reactive dhayi.
Zvakanakira reactive dhayi:
1. Nekuda kwekugona kwayo kuita nepakati, inopa reactive dhayi mukana wakakura nekuti anowedzera kusimba uye anooneka akasiyana.Ichi chimiro chinochipa mukana wakasimba mukurambidza ruvara uye cellulose ruvara.
2. Pane imwe simba rakasimba rekuita dhayi, ndiko kuti, kukurumidza kwayo kunyorova, iyo inowanikwa kuburikidza nekubudirira uye yakananga coloring process.
3. Madhayi anogadzirisa akakodzera kudhaya zvigadzirwa zvitsva zvefiber cellulose senge lyocellfibers.
4. Zviri nyore kuchenesa: Fiber dzakadhayiwa nedhayi dzinoshanda dzinogona kudhayiwa zvakachengeteka nehembe chena pasina njodzi yekudhaya.
Kunyangwe kushandiswa kwedhayi reactive kune zvakawanda zvakanakira, kune zvimwewo zvazvakaipira, sekukanganisa kwedhayi reactive pane zvakatipoteredza.Nekudaro, vanogadzira dhayi vanogadzira dhayi muIndia nepasirese vakaisa simba rakawanda uye zviwanikwa mukutsvagisa kuvabatsira kugadzira zvigadzirwa zvinotapukira zvisikwa uku vachipa vatengi kukosha kwakakura uye kunoramba kuchienderera.Mamwe matambudziko akatarisana neindasitiri iyi anosanganisira kutsvaga vashandi vane hunyanzvi uye vane tarenda, mitemo yehurumende, uye mutengo wekugadzira.Kunyangwe iyo indasitiri ine ramangwana rakajeka, zvakakosha kufambira mberi munzvimbo dzese dziri pamusoro kudzivirira chero zvipingamupinyi.
Iyo reactive dyeing kemikari inopindirana ne cellulose, ichigadzira covalent bond pakati pedhayi morekuru uye cellulose.
Ko reactive dhayi ane hushamwari zvakatipoteredza?
Kana tikafunga kushandiswa kwedhayi reactive, ipapo reactive dhayi dzinofanirwa kuve dzakatenderedza nharaunda.
Chii chinoshandiswa checovalent bonds mune reactive dyes?
Covalent bonds anoshandiswa mune reactive dhayi kuti aite akakwira mukutsanya.
