Kukohwa kwekotoni uye imwe cellulosic fibers
Scouring ndiyo yakanyanya kunyorova nzira inoshandiswa kune machira isati yadhayiwa kana kudhindwa.Kunyanya inzira yekuchenesa umo zvinhu zvekunze kana tsvina zvinobviswa.Iyo scouring process, panguva yekuchenesa α-cellulose, inopa iyo hydrophilic hunhu uye permeability inodiwa kune anotevera maitiro (bleaching, mercerizing, dyeing kana kudhinda).Kukwesha kwakanaka ndiyo hwaro hwekupedza kunobudirira.Kuitwa kwemaitiro ekutsvaira kunotongwa nekuvandudzwa kwekunyorova kweiyo scoured material.
Kunyanya kunyanya, kukweshwa kunoitwa kuitira kubvisa mafuta asingadikanwi, mafuta, wakisi, tsvina inonyungudika uye chero tsvina yakasviba kana yakasimba inonamatira kune fiber, izvo zvingakanganisa kudhaya, kudhinda uye kupedzisa maitiro.Maitiro acho anosanganisira kurapwa nesipo kana detergent ine kana pasina kuwedzera alkali.Zvichienderana nemhando yefiber, alkali inogona kunge isina simba (semuenzaniso soda ash) kana yakasimba (caustic soda).
Kana sipo inoshandiswa, mvura yakanaka inodiwa.Ioni yesimbi (Fe3+uye Ca2+) iripo mumvura yakaoma uye pectin yedonje inogona kugadzira sipo isinganyunguriki.Dambudziko rinonyanya kuoma kana scouring ichiitwa mukuenderera mberi kunosanganisira kugezesa padding uko chiyero chedoro chakaderera zvakanyanya pane mubatch process;iyo chelating kana sequestering agent, semuenzaniso, Ethylenediaminetetraacetic acid (EDTA), Nitrilotriacetic acid (NTA), nezvimwewo, inogona kushandiswa kudzivirira scum uye kuumbwa kwemafirimu.Iyo yemhando yepamusoro yekugadzira detergent inopa chiyero chakanaka nekunyorova, kuchenesa, emulsifying, kuparadzira uye kupupa zvinhu, nekudaro ichipa yakanaka yekuchenesa kugona.Anionic, non-ionic detergents kana mablends awo, solvent-assisted detergent blends uye sipo zvinonyanya kushandiswa pakukwesha.Kuti ikurumidze kukorokoza, maajenti ekunyorova pamwe chete nemafuta ekubira zvakanyanya (cyclohexanol, methylcyclohexanol, nezvimwewo) dzimwe nguva anoshandiswa, asi maitiro anogona kunge asiri eco-friendly.Basa rezvinonyungudutsa rinonyanya kunyungudutsa mafuta asina kunyungudika uye wakisi.
Vavaki vanowedzerwa kune kier-boiling bath kuti vawedzere basa resipo kana detergent.Aya anowanzo munyu senge borates, silicates, phosphates, sodium chloride kana sodium sulphate.Sodium metasilicate (Na2SiO3, 5H2O) inogona kuitawo sedetergent uye buffer.Basa rebuffer kutyaira sipo kubva pachikamu chemvura kuenda kune jira / mvura interface uye nekudaro kuwedzera kusungirirwa kwesipo pamucheka.
Panguva yekubikirwa donje ne caustic soda, mweya wakavharirwa unogona kukonzera oxidation ye cellulose.Izvi zvinogona kudzivirirwa nekuwedzera kweinoderedza nyoro yakadai sesodium bisulphite kana kunyange hydrosulphite mudoro rekutsvaira.
Maitiro ekutsvaira emhando dzakasiyana dzemachira anosiyana zvakanyanya.Pakati pemafibhi echisikigo, pamba mbishi inowanikwa mune yakanyanya kuchena fomu.Huwandu hwetsvina hunofanira kubviswa huri pasi pe10% yehuremu hwose.Zvakadaro, kufashaira kwenguva refu kunodiwa sezvo donje rine wakisi huremu hwemamorekuru, ayo akaoma kubvisa.Mapuroteni zvakare akarara mukati memukati mefiber (lumen) iyo isingasvikike kune kemikari inoshandiswa mukukwesha.Sezvineiwo cellulose haibatwe nekurapa kwenguva refu necaustic solution kusvika pachikamu che2% pasina mweya.Nokudaro, zvinokwanisika kushandura tsvina yose panguva yekutsvaira, kunze kwezvinhu zvemavara echisikigo, kuita soluble form, iyo inogona kushambidzwa nemvura.
Kuchekwa kwema cellulosic fibers kunze kwedonje kuri nyore.Bast fibers senge jute uye fl ax haigone kucheneswa zvakati wandei nekuda kwemukana wekubvisa akati wandei asiri-fibrous zvikamu nemhedzisiro yekukuvara kwezvinhu.Izvi zvinowanzogezwa nesipo kana detergent pamwe chete nesoda ash.Jute inowanzoshandiswa pasina kumwe kucheneswa, asi fl demo uye ramie zvinowanzocheneswa uye zvinowanzocheneswa.Jute yekudhaya inofanochekwa asi huwandu hwakati wandei hwe lignin hunoramba huripo, zvichikonzera kusasimba kwechiedza.
Sezvo kusvibiswa kwechisikigo kwakadai sekotoni wax, pectic zvinhu uye mapuroteni zvakabatanidzwa zvakanyanya mukati memadziro ekutanga, iyo scouring process ine chinangwa chekubvisa madziro aya.
