Kudhaya uye kupedza nzira (2)

Kudhaya inzira yekugadzirisa kuburikidza nemuviri kana wemuviri wemakemikari musanganiswa wedhayi (kana pigment) uye machira ekugadzira machira anowana kupenya, yunifomu uye yakasimba ruvara.

Iyo machira inonyudzwa mudhayi ine aqueous solution pane imwe tembiricha, dhayi inofamba kubva mumvura ichienda kune fiber, panguva ino dhayi iri mumvura inodzikira zvishoma nezvishoma, nepo huwandu hwedhayi pane machira hunowedzera zvishoma nezvishoma, mushure menguva yenguva, huwandu hwedhayi mumvura uye huwandu hwedhayi pamucheka wemucheka hauchachinji, huwandu hwedhayi hahuna kuchinja, huwandu hwedhayi hahuna kushanduka. equilibrium.

Dhayi inobviswa mumvura ndiyo dhayi inoenda pa fiber. Bvisa fiber chero nguva, kunyangwe yakamonyoroka, dhayi inoramba iri mufayibha, uye haigone kungoita dhayi zvachose kunze kwefiber, dhayi iyi yakasanganiswa mune fiber phenomenon, inonzi dhayi.

Zvinoenderana neakasiyana ekugadzira dhayi zvinhu, nzira dzekudhaya dzinogona kukamurwa zvakanyanya kuita zvipfeko zvekudhaya,kudhaya machira(main ekuwedzera machira ekudhaya, machira akarukwa dhayi uye neasina kuruka dhayi), shinda yedhayi (inogona kupatsanurwa kuita Hank dyeing, bobbin dyeing, warp dhayi uye inoenderera mberi dhayi yewarp) uye loose fiber dyeing mapoka mana.

Pakati pazvo, kudhaya machira ndiko kunonyanya kushandiswa, kudhayiwa kwembatya kunoreva nzira yekudhayira machira mushure mekugadzirwa mune zvipfeko, kudhaya kweshinda kunonyanya kushandiswa kugadzira machira emucheka wemavara uye machira akarukwa, uye yakasununguka fiber dyeing inonyanya kushandiswa kugadzira mavara machira.

Zvinoenderana nemhando dzakasiyana dzekubatana pakati pedhayi nemucheka (dhayi maitiro), inogona kupatsanurwa mumhando mbiri dzekunyudza dhayi uye padhi dhayi.

1. Dhinda maruva

Kudhindandiyo nzira iyo dhayi kana pendi inoumba pateni pajira. Yakakamurwa kuita flat screen printing, denderedzwa screen kudhinda, kutamisa kudhinda, digital printing zvichingodaro. Kudhinda kudhaya kwenzvimbo, kunoda imwe color fastness. Dhayi inoshandiswa yakangofanana nekudhaya, kunyanya kushandisa nzira yekudhinda yakananga, inogonawo kushandisa kudhinda kwependi, kudhinda kwependi iri nyore, asi yakadhindwa yakakura nzvimbo muenzaniso inonzwa yakaoma.

2.Pedzisa

Textile kupedzisa, inozivikanwawo sekupedzisa. Ndiyo nzira yekugadzirisa yekuvandudza kunzwa uye kutaridzika kwemucheka (zvakadai sekupedza kuoma, kupedzisa kunyoro, calendering kana kusimudza, nezvimwewo), kuvandudza kunaka kwejira uye kupa machira mabasa matsva (akadai se anti-wrinkle, mvura, anti-fouling, anti-corrosion, anti-mildew, anti-moth uye anti-bacteria, nezvimwewo) kuburikidza nemakemikari uye emuviri, nzira dzemakemikari, nezvimwewo.

Generalized: Yese maitiro ekugadzirisa anovandudza nekuvandudza mhando mushure mekuruka.

Narrow: jira mukudzidzira kuita bleaching, dhayi uye kudhinda maitiro anonzi textile finishing.

Chinangwa chekupedzisa

(1) Ita saizi yejira uye chimiro chigadzikane

Kuburikidza nekupedzisa, hupamhi hwemukova hunosimbiswa uye shrinkage rate inoderedzwa, kuitira kuti jira regonhi rejira rive rakashambidzika uye rakafanana, uye saizi yejira uye fomu yesangano zvinosangana nezviyero zvakatemwa.

Semuyenzaniso: stentering - kushandisa faibha, sirika, makushe uye mamwe faibha mune nyoro kana hunyoro mamiriro ane imwe plasticity, jira upamhi zvishoma nezvishoma kukwevera kuhukuru hwakatarwa uye kugadzikana kuomesa kupedzisa muitiro, anonziwo tentering.

Kuisa kupisa - kunoreva tekinoroji yekugadzirisa yejira rekugadzira fiber pasi pekunetsekana kwekupisa kupisa kuita kuti saizi yayo uye chimiro chigadzikane.

(2) Kuvandudza chitarisiko chembatya machira

Kuvandudza kuchena uye kudhirowa kwejira, kunatsiridza kupenya kwejira kwejira uye kupa chimiro chepamusoro chejira.

Calender kupedzisa - necalender, semuenzaniso, kushushikana kwemagetsi, kuita kwekupisa uye kunyorova, nerubatsiro rwefiber plasticity, ita kuti faibha yepasi iratidze kurongeka kwakafanana, kuitira kuvandudza iyo yakatsetseka pamusoro roughness, chiedza chekuratidzira mitemo, uyezve kuwedzera jira ruvara uye kupenya.

Calender kupedzisa - Calender yekupedzisa muchina inoumbwa neyakaoma yakaoma roll uye yakapfava roll. Iyo pamusoro peiyo yakaoma roll yakanyorwa neYang pateni, uye iyo yakapfava roll yakanyorwa neYin pateni, iyo inopindirana kune mumwe nemumwe. Nekubatsirwa kwepurasitiki yemucheka pasi pemamiriro ekupisa uye ane hunyoro, mhedzisiro ye embossing pattern pamucheka inogadzirwa nekushandiswa kweyin-yang roller rolling.

Kukuya - Mushure mekupedza jira rinogona kuburitsa suede, inzwa yakavandudzwa, yakasununguka kupfeka, inogona kuitwa pamushini wekudhirowa, jira mushure mekupokana kwakadzokororwa kugadzira suede.

4. Kuvandudza kunzwa kwezvipfekojira

Kupa jira rakapfava, rakapfava kana rakasimba.

Semuyenzaniso: iyo yakapfava kupedzisa - ndeye gadzira jira rinonzwa kuomarara uye rough hurema hunoita iyo yakapfava machira ekugadzirisa maitiro. Kusanganisira mechanical soft finishing, kemikari yakapfava kupedzisa uye kupera kwakasimba.

Mechanical yakapfava kupedzisa inonyanya kushandisa nzira dzemakanika kukanya jira kakawanda mumamiriro ekunetsana kuti kuderedze kuomarara kwejira uye kudzosera kune kupfava kwakakodzera.

Iyo kemikari nzira inoshandisa chiito chekupfava kuti kuderedze coefficient of friction pakati pefibers kuti uwane nyoro.

Kupedzisa kuoma - kuita kuti jira rive rakatsetseka, rakaomarara, gobvu, kunzwa kwakazara, uye kunatsiridza simba uye kupfeka kuramba, kunogonawo kuvandudza kurembera uye kutaridzika.

Kuomesa kupedzisa kugadzirisa kunowanzo kusanganiswa nehupamhi hwakagadziriswa, kuwedzera kupfava kune slurry kuti uvandudze manzwiro akazara, zvakafanana, kupedzisa kupfava kwakapfava, kuwedzera kuomesa mumiriri kuwedzera mapfupa emuviri wayo.

5. Ipa machira zvinhu zvakakosha

Kupa jira zvimwe zvinhu zvekudzivirira kana kuvandudza mapfekero ejira.

Semuenzaniso: kudzivirira mvura, ndeyekupfekedza machira, mvura nemhepo hazvigone kupinda; Mvura inodzinga kupedzisa ndeye kushandura iyo hydrophilic pamusoro pefiber kuita hydrophobic, uye jira racho rinofema uye harisi nyore kunyorova nemvura.

Kupera kwemoto-retardant - jira rakapedzwa rine madhigirii akasiyana ekukwanisa kudzivirira kupararira kwemurazvo, uye rinogona kukurumidza kumira kupisa mushure mekusiya moto.
