Kuvandudzwa kweReactive Dyeing Technology
Mumakore achangopfuura, nzira itsva yekudhaya yekudhaya inoshanduka yakakurumidza kukura.Ikozvino reactive dhayi maitiro anosanganisira: reactive dhayi pad dhayi uye pfupi steaming dhayi, reactive dhayi dip dyeing pfupi nzira, reactive dhayi yakaderera tembiricha uye inotonhora pad batch dyeing, uye kwazvakarerekera fixing agent dhayi , Reactive dhayi yakaderera-munyu uye isina munyu dhayi, shandisa "inotsiva munyu" reactive dhayi yakaderera-munyu dhayi, reactive dhayi yakaderera-alkali uye kusarerekera dhayi.
1.Reactive dhayi pad dyeing uye kunyorova pfupi steam dyeing.Pad dyeing ndiyo imwe yedzakakosha nzira dzekudhaya dzeanoshanda dhayi.Nekudaro, mushure mekuti jira racho rakamisikidzwa nepedhi dhayi mhinduro, kuomeswa kwepakati kunodiwa kufambisa kunotevera kupisa, kana kuwedzera kukurumidza kwekugadzirisa panguva yekubika nekugadzirisa.Uye kuderedza dhayi hydrolysis, uye kuwana yakakwirira fixation mwero uye ruvara kukurumidza.Kuomeswa kwepakati kuchaunza matambudziko mazhinji: kushandiswa kwesimba, huwandu hwakawanda hwesimba hwekupisa hunopedzwa pakuomesa micheka yakanyorova kuti ibudise mvura;madhayi anowanzoita kutama panguva yekuomeswa, zvichikonzera kusiyana kwemavara uye kuderedzwa kwemavara kukurumidza, uye kudhaya kubereka zvakare kwakashata;Kuomeswa mushure mekunyura mhinduro yekudhaya hakungowedzeri maitiro ekugadzirisa uye hazvigoneke kubata, asiwo kana jira rakaoma richipisa, dhayi nemakemikari zvinofanirwa kutora mvura kuti iparadze zvakare.Mucheka wakaoma unobudisa kupisa kana unotora unyoro, zvichikonzera kupisa, izvo zvinokanganisa kudhaya nekugadzirisa.Naizvozvo, kupfungaira ivavariro yenguva refu iyo vanhu vanoronda.Zvakaoma zvikuru kupfungaira machira anedhayi.Chekutanga, jira rakanyorova rinobikwa zvakananga.Nemhaka yokuti unyoro hunotora kupisa uye hunoputika, jira rekupisa rinononoka, iro rinowedzera nguva yekupisa nekugadzirisa;chechipiri, jira rine hunyoro hwakawanda (kazhinji chiyero chemvura mushure mekuputira ndeye 60% kusvika 70%), mukugadzirwa kwekupisa uye kupisa, madhayi anogadzirisa pamucheka achawana yakawanda ye hydrolysis, iyo inoderedza kugadzirisa. chiyero uye kutsanya kwemavara.Hunyoro huri pamucheka hune nyika dzakawanda, dzinogona kukamurwa kuita zvikamu zviviri: iyo fiber yakanyura mvura uye yemahara mvura pamucheka.Mvura yakasungwa nekemikari inotora mvura (inonyanya kusungirirwa kune fiber molecular chain kuburikidza nehydrogen bonds) inonziwo unfreeze mvura (inotonhora yakadzika kudarika 0 ° C).Ichi chikamu chemukati memvura hachina zvakawanda, uye mukana wekuita nedhayi zvakare kushoma, nekuti Haikwanise kufamba zvakasununguka.Chikamu chikuru chemvura yakanyungudutswa iri mufiber pores.Iyo fiber pores yakanyanya kutetepa.Ichi chikamu chemvura hachisi nyore kuyerera zvakasununguka, saka chinonziwo mvura yakasungwa.Maitiro ayo ekuita nedhayi zvakare yakaderera.Kunyange zvazvo chikamu chemvura yakasununguka kunze kwefiber iri mu-inter-fiber capillary uye haisi nyore kuyerera nekuda kweiyo capillary effect, yakawanda inogona kuyerera yakasununguka.Mvura iri mumatunhu maviri aya kunze kwefiber iri nyore kuita nedhayi.Kana iyo dhayi yakakwira, inodiwa kuti dhayi irege kuita yakawanda ye hydrolysis, uye kukurumidza kugadzirisa kunoitika mushure mekusvika pakupisa kwakanyanya.Nechikonzero ichi, iyo alkali agent yakakodzera kushandiswa inofanirwa kuve isina kusimba, kana alkalinity haifanirwe kuve yakasimba kana mwando wejira wakakwira (kusanganisira yakasanganiswa alkali yekubika soda kana soda ash uye mamwe alkali agents), kana yakaderera alkali. kana kusarerekera kugadzika kunoitwa Mhedzisiro ichava nani.Zvidzidzo zvakaona kuti kushandiswa kweasina kwazvakarerekera kugadzirisa agent kugadzirisa ruvara kune yakanaka mhedzisiro pa120～130℃ kana 180℃.
2.Short reactive dye dip dyeing process inopfupisa reactive dye dyeing process, inovandudza kugadzirwa kwekugadzira, inochengetedza simba, inochengetedza mvura, uye inoderedza kuyerera kwetsvina.Kudhaya mupfunga mupfupi wakanyorova inzira pfupi yekudhaya dhayi padhi.Iyo pfupi-yekuyerera dhayi maitiro e dip dyeing zvakare itariso yekutsvagisa mumakore achangopfuura, kuvandudza michina, kupfupisa nguva yekudhaya, uye zvakanyanya kukosha, zvine musoro kudzora maitiro ekudhaya, uye otomatiki kutonga komputa kunogona kupfupisa kudhaya, kugadzirisa uye kuwacha. nguva.Mumakore achangopfuura, makambani akawanda anogadzira dhayi akagadzira nzira dzekudhaya nekukurumidza kuitira kuti vashambadzire zvigadzirwa zvavo.Nheyo yekukurumidza kudhaya maitiro ndeyekusarudza madhayi zvine hungwaru maererano nehunhu hwawo, uye kupfupisa nguva yese yekudhaya pasi pechimiro chekuona kuenzana kwakanaka uye kuberekana.Tora inodzorwa metering uye inoenderera yekuwedzera, iyo inogona kupfupisa nguva.Chengetedza zvakanyanya dhayi, alkali uye munyu, uye kuderedza kuyerera kwetsvina.Mamwe maitiro anodzorawo otomatiki kugeza mushure mekudhaya kuti uwedzere kuchengetedza mvura uye kuderedza tsvina.Vamwe vagadziri vedhayi kana midziyo vakagadzirawo akasiyana-siyana akazvipira anodzora ekudhaya software.
Isu tiri Reactive Dyeing mutengesi.Kana iwe uchifarira zvigadzirwa zvedu, ndapota inzwa wakasununguka kutibata nesu.
