Kudhinda, sekusiyaniswa kubva kudhayi, nzira iyo dhayi kana jira rinoshandiswa kune jira kuti riite muenzaniso.

Muna 1784, varume vatatu vekuFrance vakatanga fekitari yekutanga pasi rose yekudhinda donje.

Mumakore 230 apfuura, unyanzvi hwokudhinda hwakagadzirwa nenzira dzakasiyana-siyana.Nhasi, encyclopedia xiaobian ichaongorora mhando dzekudhinda

I. Classification maererano nekudhinda maitiro:

1. Kudhinda zvakananga (Kudhinda pamusoro, Kudhinda kwakanyorova)

Kudhinda kwakananga imhando yekudhinda yakananga pajira jena kana pamucheka wakagara wakadhayiwa.Iyo yekupedzisira inonzi overprint (inozivikanwawo seyepasi kudhinda), uye zvechokwadi kudhindwa kwakasviba zvakanyanya kupfuura ruvara rwepasi.Inenge 80% yemachira akadhindwa pamusika anodhindwa zvakananga.(Pano kudhinda kwakananga kunowanzo reva kudhindwa kwedhayi, inoshandiswa kusiyanisa kubva pakudhindwa kwependi pazasi)

Mubvunzo: Nzira yekusiyanisa sei chena kudhindwa kubva kune dhayi kudhindwa?

Kana ruvara rwemashure emucheka rwuri mumvuri wakafanana kumativi ose (nekuda kwechidimbu dhayi) uye kudhindwa kwakasviba zvakanyanya kupfuura ruvara rwemashure, zvino ivhavha yekuvhara, kana zvisina kudaro ichena kudhindwa.

2. Discharge kudhinda

Sarudza kwete dhayi kuti udhaye hwaro hwekuburitsa paste, kuramba kuoma, shandisa detergent ine discharge agent kana nekupokana kuburitsa panguva imwechete dhizaini uye ruvara rwedhayi yekudhinda paste kudhinda, post-processing, yakadhindwa muvhu inoparadzwa uye iyo decolorization yedhayi, ruvara rwepasi rwakaumba chena pateni (inonzi chena inobuda) kana ruvara pateni inoumbwa nedhizaini uye ruvara dhayi dhayi (inonzi kudhinda kwemavara).Iyo inozivikanwawo sekudhonza chena kana ruvara kudhonza.

Kusiyana nekudhinda kwakananga, mari yekugadzira micheka yakadhindwa yakakwirira, uye kuchenjerera kukuru uye kunyatsojeka kunofanira kutorwa kudzora kushandiswa kwemugadziri wekudzikisa anodiwa.

Mubvunzo: Nzira yekusiyanisa sei kana jira racho riri discharge print?

Kana jira rine ruvara rwakafanana kumativi ose emashure (nokuti dhayi yechidimbu), uye muenzaniso wakachena kana wakasiyana kubva kumashure, uye kumashure kwakasviba, kunogona kusimbiswa semucheka wekudhinda.

Kunyatsoongorora kuseri kwepatani kunoburitsa zvisaririra zveruvara rwepakutanga (izvi zvinoitika nekuti makemikari anoparadza dhayi haapinde zvizere mumucheka).

3, anti-dyeing kudhinda

Kemikari kana waxy resin yakadhindwa pamucheka muchena unodzivirira kana kudzivirira kupinda kwedhayi mumucheka.Chinangwa ndechekupa chigadziko chemavara chinozoratidza patani chena.Ziva kuti mhedzisiro yacho yakafanana neyekuburitsa kudhinda, zvisinei nzira inoshandiswa kuita iyi mhedzisiro inopesana nekuburitsa kudhinda.

Kudhinda dhinda nzira haisati yanyanya kushandiswa, kazhinji kumashure haigone kushandiswa mune yekubvisa.Kudhinda kwedhayi kwakawanda kunoitwa nenzira dzakaita sehunyanzvi kana kudhinda nemaoko (eg kudhinda wax) kwete pakugadzirwa kwehuwandu.

Nekuti kudhinda kudhinda uye kudhinda-dhayi kunoburitsa zvakafanana kudhinda, saka kazhinji kuburikidza nekutarisa kwakashama kwemaziso kazhinji hazvigone kuzivikanwa.

Kupisa print (Burn out print)

Chinyorwa chakaora chimiro chinodhindwa nekemikari inopwanya jira.Saka kusangana pakati pemakemikari nemucheka kunogona kuburitsa maburi.Mipendero yemaburi mune akadhinda akadhinda anogara akasakara nguva isati yakwana, saka jira racho harina kusakara kupfeka.

Imwe mhando yekudhinda yakaora ijira rakagadzirwa neshinda dzakasanganiswa, core-spun yarns, kana musanganiswa wemafiber maviri kana anopfuura.Makemikari anogona kuparadza faibha imwe (cellulose), ichisiya mamwe akasimba.Iyi nzira yekudhinda inogona kugadzira akawanda akakosha uye anonakidza machira ekudhinda.

5, kuunyana shrinkage ruva / furo kudhinda

Kushandisa nzira yekudhinda pamucheka wekushandiswa kweko kwemakemikari kunogona kuita kuti fiber iwedzere kana kuputika, kuburikidza nekurapa kwakakodzera, kuitira kuti chikamu chakadhindwa chefiber uye chikamu chisina kudhindwa chekuwedzera kwefiber kana kupesana kwekugadzirisa, kuitira kuti uwane. pamusoro peiyo nguva dzose concave uye convex muenzaniso wechigadzirwa.Zvakadai sekushandiswa kwe caustic soda puffing agent ye pure cotton yakadhindwa seersucker.Iyo inozivikanwawo seconvex kudhinda.

Tembiricha yekupupa inowanzoita 110C, nguva yacho masekonzi makumi matatu, uye sikirini yekudhinda ndeye 80-100 mesh.

6, Coating kudhinda (Pigment Print)

Nekuti iyo yekupfekedza haisi yemvura-inonyungudika yemavara zvinhu, hapana hukama kune faibha, ruvara rwayo runofanira kuvimba nefirimu rinogadzira polymer compound (adhesive) coating uye fiber adhesion kuti ibudirire.

Coating material printing inogona kushandiswa kugadzirisa chero machira efayibha, uye ine zvimwe zvakanakira kudhinda mablends uye interweave, uye maitirwo acho ari nyore, akafara spectrum, maruva chimiro rondedzero yakajeka, asi kunzwa hakuna kunaka, kukwesha. kutsanya hakuna kukwirira.

Kudhinda kwependi ndiko kudhindwa kwakananga kwepende, iyo inowanzonzi yakaoma kudhinda kuti isiyanise kubva pakadhinda nyoro (kana kudhinda dhayi).

Ivo vane yakanaka kana kunyange yakanakisa chiedza kukurumidza uye yakaoma kuchenesa kukurumidza, saka ivo vanoshandiswa zvakanyanya mumachira ekushongedza, machira emaketeni uye zvipfeko zvinoda kucheneswa kwakaoma.
