Nzira yekudzivirira sei Sulfur Nhema Tender yeCotton Fiber?

Dhayi dzesarufa dzinonyanya kushandiswa kudhaya machira edonje, uyezve machira akasanganiswa edonje/vinylon. Iyo yakanyungudutswa mu sodium sulfide uye isarudzo yakanaka kune yakasviba zvigadzirwa zve cellulose fiber, kunyanya yeSulfur Black 240% uye Sulfur Blue 7dyeing. Mubereki wedhayi dzesarufa haana hukama kune fiber, uye chimiro chayo chine sulfur bonds (-S-), disulfide bonds (-SS) kana polysulfide bonds (-Sx-), iyo yakaderedzwa kuita sulfhydryl mapoka (-SNa) pasi pe chiito che sodium sulfide reductant.Inova mvura-inonyungudika leuco sodium munyu. Leuco ine hukama hwakanaka hwema cellulose fibers nekuda kwemamorekuru makuru edhayi, anoburitsa hombe Van der Waals uye hydrogen bonding masimba ane fiber. Kunyangwe ruvara rwemavara esarufa dhayi asina kukwana, kunyanya bhuruu nedema, ruvara haruna kupenya, asi kugadzirwa kwayo kuri nyore, mutengo wakaderera, maitiro ekudhaya ari nyore, kuenzanisa kwemavara kuri nyore, uye kukurumidza kweruvara kwakanaka. .Zvinofanira kucherechedzwa, zvisinei, kuti mamwe madhayi esarufa, akadai sesarufa dema, anogona kukonzera nyoro yeCotton Fiber.

Iyo nyoro yefiber inoda kutariswa mushure meiyoSulfur Black 240%dhayi inoshandiswa kudhaya. Zvimwe zvinhu zvinogona kuwedzera njodzi yefiber brittleness, senge kushandisa zvakanyanya madhayi, izvo zvisingango wedzera mukana we brittleness, asi zvakare zvinoderedza kutsanya kwemavara uye kuita kuti kugeza kuome. Mukuwedzera, mushure mekudhayiwa, inofanira kushambidzwa zvakakwana kudzivirira kushambidzwa kusina kuchena, uye ruvara rwakayangarara pashinda iri nyore kuparara kuva sulfuric acid panguva yekuchengetedza, iyo inoita kuti fiber iite brittle.

Kuderedza kana kudzivirira fiber nyoro, zvinotevera matanho anogona kutorwa:

1. Deredza kuyerwa kwesarufa dema dhayi: muyero wemercerizing yakakosha dhayi yemuvara haipfuure 700 G/package.

2. Mushure mekudhaya, nyatsogeza nemvura kuti udzivise ruvara rwakayangarara kubva pakuora kuita sulfur acid panguva yekuchengetedza.

3. Shandisa anti-tender treatment agents, zvakadai seurea, soda ash, sodium acetate, nezvimwewo.

4. Mwero weshinda yakakweshwa mvura ishoma pane yeshinda yakakweshwa alkali.

5. Pukuta shinda yakadhayiwa nenguva kuti udziye kupisa kweshinda yakanyorova mukurongedza, zvichikonzera kuderedzwa kweanti-brittleness agent content uye pH kukosha.
