Disperse dhayi ndiyo inonyanya kukosha uye chikamu chikuru muindasitiri yedhayi.Izvo hazvina mapoka akasimba-anonyungudika mumvura uye haasi-ionic dhayi anodhayiwa munzvimbo yakapararira panguva yekudhaya.Inonyanya kushandiswa kudhinda uye kudhayiwa kwepolyester nemachira ayo akasanganiswa.Inogona zvakare kushandiswa mukudhinda uye kudhayira mafiber ekugadzira akadai seacetate fiber, naironi, polypropylene, vinyl, uye acrylic.
Mhedziso yekuparadzira dhayi
1. Nhanganyaya:
Disperse dye imhando yedhayi inonyungudika zvishoma mumvura uye inoparadzirwa zvakanyanya mumvura nekuita kwekuparadzira.Kuparadzira madhayi haana mapoka anonyungudika nemvura uye ane huremu hwakaderera.Kunyangwe aine mapoka epolar (akadai sehydroxyl, amino, hydroxyalkylamino, cyanoalkylamino, nezvimwewo), achiri madhayi asiri e-ionic.Dhayi dzakadaro dzine hukuru hwemashure ekurapa, uye dzinowanzoda kuwirwa neguyo pamberi pechigadziro kuti ive yakanyanya kupararira uye crystal-stable particles isati yashandiswa.Iyo dhayi doro rekuparadzira dhayi ndeye yunifomu uye yakagadzikana kuturika.
2. Nhoroondo:
Disperse dhayi dzakagadzirwa kuGermany muna 1922 uye dzinonyanya kushandiswa kudhaya polyester fiber uye acetate fiber.Yainyanya kushandiswa kudhayiwa acetate fiber panguva iyoyo.Mushure memakore ekuma1950, nekubuda kwepolyester fibers, yakakurumidza kukura uye yava chigadzirwa chikuru muindasitiri yedhayi.
Kurongeka kwemadhayi anoparadzira
1. Kukamurwa nechimiro chemolecular:
Zvinoenderana neiyo molecular chimiro, inogona kukamurwa kuita matatu marudzi: azo type, anthraquinone mhando uye heterocyclic mhando.
Azo-mhando chromatographic agents akazara, ane yero, orenji, tsvuku, yepepuru, yebhuruu nemamwe mavara.Azo-mhando yekuparadzira dhayi inogona kugadzirwa zvinoenderana neyakajairwa azo dye synthesis nzira, maitiro ari nyore uye mutengo wakaderera.(Kuverengera kunosvika makumi manomwe neshanu muzana edhayi dzekuparadzira) Mhando yeAnthraquinone ine tsvuku, yepepuru, yebhuruu nemamwe mavara.(Accounting for about 20% of disperse dyes) Mujaho wedhayi unozivikanwa, anthraquinone-based dye heterocyclic type, imhando ichangobva kugadzirwa yedhayi, ine hunhu hweruvara rwakajeka.(The heterocyclic type accounts about 5% of the disperse dyes) Nzira yekugadzirwa kwemhando yeanthraquinone uye heterocyclic type disperse dyes inonyanya kuoma uye mutengo wakakwirira.
2. Kupatsanurwa zvinoenderana nekupisa kupisa kwechikumbiro:
Inogona kukamurwa kuva yakaderera tembiricha mhando, yepakati tembiricha mhando uye yakakwirira tembiricha mhando.
Kudzikira tembiricha dhayi, yakaderera sublimation kukurumidza, yakanaka kuyera kuita, yakakodzera kupera simba dhayi, inowanzonzi E-mhando dhayi;tembiricha dhayi, yakakwirira sublimation kutsanya, asi hurombo mwero, yakakodzera inopisa melt dyeing, inozivikanwa seS-mhando dhayi;dhayi dzepakati-tembiricha, ane sublimation fastness pakati pezviviri zviri pamusoro, inozivikanwawo seSE-mhando dhayi.
3. Terminology ine chekuita nekuparadzira dhayi
1. Kutsanya kwemavara:
Rudzi rwemicheka runopokana neakasiyana emuviri, kemikari uye biochemical mhedzisiro mukudhaya uye kupedza maitiro kana mukuita kwekushandisa nekushandisa.2. Kudzika kwakajairika:
Mutsara wezviyero zvinozivikanwa zvakadzama zvinotsanangura kudzika kwepakati se 1/1 mwero wakadzika.Mavara ehumwe chiyero chakadzika akaenzana mupfungwa, kuitira kuti kukurumidza kwemavara kunogona kuenzaniswa pahwaro humwe.Parizvino, yakakura kusvika pahupamhi hutanhatu hwakadzika hwakadzika hwe2/1, 1/1, 1/3, 1/6, 1/12 uye 1/25.3. Kudzika kwedhayi:
Inoratidzwa sechikamu chehuremu hwedhayi kusvika kune huremu hwefiber, huwandu hwedhayi hunosiyana zvichienderana nemavara akasiyana.Kazhinji, kudzika kwedhayi i1%, kudzika kwenavy blue i2%, uye kudhaya kwevatema i4%.4. Kuchinja:
Shanduko yemumvuri, kudzika kana kupenya kwemavara emucheka wakadhayiwa mushure meimwe kurapwa, kana mhedzisiro yakasanganiswa yekuchinja uku.5. Stain:
Mushure meimwe nzira yekurapa, ruvara rwemucheka wakadhayiwa unotamirwa kune jira riri pedo, uye jira rekugadzira rakasvibiswa.6. Gray sampu yekadhi yekuongorora discoloration:
Muyedzo yekumhanya kwemavara, iyo yakajairwa grey sampu kadhi rinoshandiswa kuongorora dhigirii rekudzikira kwechinhu chakadhayiwa chinowanzonzi discoloration sampuli kadhi.7. Kadhi re grey rekuongorora tsvina:
Muyedzo yekumhanya kwemavara, iyo yakajairwa grey kadhi remuenzaniso rinoshandiswa kuongorora dhigirii rekusviba kwechinhu chakadhayiwa kune jira rejira rinowanzodaidzwa kunzi staining sampuli kadhi.8. Rudzi rwekutsanya kwemavara:
Zvinoenderana neyeyedzo yekutsanya kwemavara, dhigirii rekushanduka kwemavara akadhayiwa uye dhigirii rekusvibisa kune machira ekutsigira, iwo mavara ekukurumidza zvimiro zvemicheka zvakayerwa.Pamusoro pekumhanya kwechiedza chesere (kunze kweAATCC yakajairwa mwenje wekukurumidza), mamwe ese ari mashanu-level system, iyo yakakwira nhanho, zviri nani kukurumidza.9. Lining jira:
Muchiyedzo chekutsanya kwemavara, kuitira kutonga chiyero chekusvibiswa kwejira rakadhayiwa kune mamwe mafibhi, jira jena risina kuvharwa rinobatwa nemucheka wakadhayiwa.
Chechina, iyo yakajairika ruvara fastness yekuparadzira dhayi
1. Kutsanya kwemavara kuchiedza:
Kugona kweruvara rwemucheka kutsungirira kuratidzwa kune mwenje wekugadzira.
2. Kutsanya kwemavara pakuwacha:
Kupikisa kwemuvara wemicheka kune chiito chekugeza chemamiriro akasiyana.
3. Kutsanya kwemavara pakukwesha:
Kupokana kwemavara emachira kukwiza kunogona kukamurwa kuita yakaoma uye kunyorova kukwesha nekukurumidza.
4. Kutsanya kwemavara kune sublimation:
Iyo dhigirii iyo ruvara rwemucheka runopesana nekupisa kupisa.
5. Kumhanya kwemavara kusvika padikita:
Kupokana kweruvara rwemachira kudikitira remunhu kunogona kukamurwa kuita asidhi uye alkali dikita kukurumidza zvichienderana neasidhi uye alkalinity yebvunzo ziya.
6. Kutsanya kwemavara pakusvuta uye kupera:
Kugona kwemachira kuramba nitrogen oxide muutsi.Pakati pekuparadzira madhayi, kunyanya ayo ane anthraquinone chimiro, madhayi anochinja ruvara kana asangana nitric oxide uye nitrogen dioxide.
7. Kutsanya kwemavara pakutsikirira kupisa:
Iko kugona kwemavara emachira kuramba ironing uye roller kugadzirisa.
8. Kutsanya kwemavara kuomesa kupisa:
Iko kugona kwemavara emucheka kupikisa kupisa kupisa kurapwa.
