Nzira yekudzivirira sei kuti simbi yekotoni isatsvedzerere?

Madhayi esulfuri anonyanya kushandiswa pakudhaya machira edonje, uye zvakare pamicheka yakasanganiswa nedonje/vinyl. Inonyungudutswa mu sodium sulfide uye isarudzo yakanaka yezvigadzirwa zvemachira e cellulose, kunyanya kuSulphur Black 240% neSulphur Blue 7dyeing. Mubereki wemadhayi esulfuri haana hukama nemachira, uye chimiro chayo chine mabhondi esulfuri (-S-), mabhondi e disulfide (-SS) kana mabhondi e polysulfide (-Sx-), ayo anoderedzwa kuita mapoka e sulfhydryl (-SNa) pasi pesimba re sodium sulfide reductant. Inova munyu we leuco sodium unonyunguduka mumvura. Leuco ine hukama hwakanaka nemafiber e cellulose nekuda kwemamorekuru makuru emadhayi, ayo anogadzira Van der Waals hombe uye hydrogen bonding forces nemafiber. Kunyangwe ruvara rwemadhayi esulfure rusina kukwana, kunyanya bhuruu nedema, ruvara rwacho haruna kupenya, asi kugadzirwa kwaro kuri nyore, mutengo wakaderera, maitiro ekudhaya ari nyore, kufananidza mavara kuri nyore, uye kukurumidza kwemavara kwakanaka. Zvisinei, zvinofanira kucherechedzwa kuti mamwe madhayi esulfure, akadai sesulfure nhema, anogona kukonzera kupfava kweCotton Fiber.

Kunyorova kwefaibha kunofanirwa kutariswa mushure mekungeSarufa Nhema 240%Dhayi inoshandiswa pakudhaya. Zvimwe zvinhu zvinogona kuwedzera njodzi yekuoma kwefayibha, zvakaita sekushandisa madhayi zvakanyanya, izvo zvisingangowedzere mukana wekuoma, asi zvinoderedzawo kukurumidza kwemavara uye zvinoita kuti kuwacha kuve kwakaoma. Pamusoro pezvo, mushure mekudhaya, inofanira kusukwa zvizere kudzivirira kusukwa kusina kuchena, uye ruvara rwunoyangarara pashinda yacho rwunoreruka kuora kuita sulfuric acid panguva yekuichengeta, izvo zvinoita kuti fayibha ioma.

Kuti kuderedza kana kudzivirira kunyorova kwefiber, matanho anotevera anogona kutorwa:

1. Deredza chiyero chedhayi nhema yesarufa: chiyero chedhayi yeruvara rwemhando yepamusoro yemercerizing hachifanirwe kudarika 700 G/pakeji.

2. Mushure mekudhaya, gezai zvakanaka nemvura kudzivirira ruvara rwunoyangarara kuti rusaora kuita sarufa acid panguva yekuchengetera.

3. Shandisa mishonga inodzivirira kunyorova, yakaita seurea, soda ash, sodium acetate, nezvimwewo.

4. Hunyoro hweshinda yakakweshwa nemvura hushoma pane hweshinda yakakweshwa nealkali.

5. Omesa shinda yakapendwa nenguva kuti isapiswe neshinda yakanyorova panguva yekurongedza, zvichikonzera kudzikira kwehuwandu hwezvinhu zvinodzivirira kupwanyika uye pH.
