Textile jira post kupedzisa inzira yehunyanzvi yekurapa iyo inopa maitiro eruvara, morphological athari (yakapfava, suede, starching, nezvimwewo) uye inoshanda mhedzisiro (isingapindiki, isiri-inofeta, isiri-ironing, isiri-moth, murazvo kuramba, nezvimwewo) kumucheka.Kupedzisa post inzira inovandudza kutaridzika uye kunzwa kwejira uye inovandudza mapfekero ekuitaiyo yakakosha pakugadzira yakakwira kukosha wedzera chigadzirwa uye kuwedzera fekitorimakwikwi.
Saka ngationei kuti ndezvipi uye zvavanogona kuziva.Isu tiripo kwauri yakakwana textile project solution.Ndapota inzwa wakasununguka taura nesu.
Stentering kupedzisa inzira inoita kushandisa kwepurasitiki ye cellulose, silika, mvere uye mamwe mafibhi pasi pemamiriro emvura kuti zvishoma nezvishoma awedzere hupamhi hwejira kune saizi yakatarwa uye kuomesa, panguva imwe chete kudzikamisa chiyero chejira.Mune mamwe maitiro akadai sekukorobha uye bleaching, kudhinda uye dhayi usati wapedza, jira rinowanzoiswa kune warp tension, iyo inomanikidza jira kuti ritambanuke munzira yewarp uye kuderera munzira yeweft, uye kuitika zvimwe zvikanganiso, senge hupamhi husina kuenzana. , mipendero yejira isina kuenzana, kunzwa kwakashata, nezvimwewo Kuti jira rive neyunifomu uye yakagadzikana upamhi, uye kuvandudza zvikanganiso zviri pamusoro uye kuderedza deformation yemucheka mukupfeka, mushure mokunge dhayi uye kupera kwakanyatsopera, jira rinoda kugadzirwa.
Ndokumbira utarise mutsva stener muchina, kuti uwane rumwe ruzivo.
2. Pre-Kuderera
Preshrinking inzira yekuderedza shrinkage yemachira mushure mekunyudzwa mumvura nenzira dzemuviri.Mukuita kuruka, kudhaya uye kupedza, jira rinosungirirwa munzira yewap, uye buckling wave kureba munzira yewarp inoderedzwa, saka kureba kuchaitika.Kana iyo hydrophilic fiber jira rakazara nemvura, iyo fiber inoputika, uye dhayamita yewarp uye weft warn inowedzera, iyo inowedzera iyo warp buckling wave kureba, inopfupisa kureba kwejira, uye inoita shrinkage.Kana jira racho rakaoma, kuzvimba kunopera, asi kukakavara pakati peshinda kuchiri kuchengetedza jira muchibvumirano chechibvumirano.Mechanical preshrinking ndeyekupfapfaidza chiutsi kana kupfapfaidza kunyorovesa jira kutanga, wozoisa
mechanical extrusion mu warp direction yekuwedzera buckling wave kureba, wobva wasunungura omesa jira.Iyo shrinkage ye pre shrunk donje jira inogona kuderedzwa kusvika pasi pe1%, uye kupfava kwejira kuchavandudzwa nekuda kweiyo mutual extrusion uye nekukwesha pakati pefiber neshinda.Mucheka wemvere wemvere unogona kuve wakare shrunk nekuzorora.Mushure mokunyikwa uye kukungurutswa mumvura inodziya kana kusaswa nemhepo, jira rinoomeswa zvishoma nezvishoma mumamiriro akasununguka, kuitira kuti jira racho ridzike mumativi ose ewarp uye weft.Mucheka shrinkage inoenderanawo nechimiro chayo.Iyo shrinkage level yemachira inowanzoongororwa ne shrinkagerate.
3.Crease-Kuramba
Iyo nzira yekushandura iyo yekutanga kuumbwa uye chimiro chefayibha, kuvandudza kusimba kwayo, uye kuita kuti jira riome pakupfeka kunonzi crease resisting finishing.Inonyanya kushandiswa kune micheka yakachena kana yakasanganiswa ye cellulose fiber, uye inogonawo kushandiswa kumucheka wesilika.After crease resistant finishing, pfuma yekudzorera yemucheka inowedzera, uye zvimwe zvinhu zvesimba uye kupfeka zvinhu zvinovandudzwa.Semuenzaniso, iyo crease resistance uye dimensional kugadzikana kwemachira ekotoni yakagadziridzwa zvakanyanya, uye kugona kwekugezesa uye nekukurumidza kuomesa kuita kunogona kuvandudzwa.Kunyangwe iyo simba uye kupfeka kuramba kunoderera kune akasiyana madhigirii, pasi pekutonga kweyakajairwa maitiro mamiriro, kuita kwayo kwekupfeka hakukanganiswe.Mukuwedzera kune crease resistance, simba rekuputsika rejira re viscose rakawedzerawo zvishoma, kunyanya kunyorova kuputsa simba.Nekudaro, crease inopokana kupedzisa kune imwe mhedzisiro pane zvimwe zvine hukama zvivakwa, senge kuputsa kurebesa kwejira kunodzikira kusvika kune akasiyana madhigirii, kushomeka kwekugeza kunosiyana neanopedzisa agent, uye kukurumidza kugeza kwezvigadzirwa zvedhayi kunovandudza, asi mamwe maajenti ekupedzisa anoderedza. kutsanya kwemamwe madhayi.
4.Kuisa Kupisa,
Thermosetting inzira yekugadzira thermoplastic fibers uye misanganiswa yavo kana machira akarukwa akagadzikana.Inonyanya kushandiswa pakugadzirisa mafibhi ekugadzira uye kusanganiswa kwawo, senge nylon kana polyester, iyo iri nyore kudonha uye kukanganisa mushure mekupisa.Thermoplastic faibha machira anoburitsa kushushikana kwemukati mukati mekugadzira machira, uye anowanzo kukwenya uye deformation pasi pekuita kwehunyoro, kupisa uye simba rekunze mukudhaya uye kupedzisa maitiro.Naizvozvo, mukugadzirwa (kunyanya mukunyorova kwekupisa senge kudhaya kana kudhinda), kazhinji, jira rinobatwa pane tembiricha yakakwira zvishoma pane iyo inotevera maitiro pasi pekunetsekana, ndiko kuti, kugadzika kwekupisa, kuitira kudzivirira shrinkage uye deformation. jira uye kufambisa kunotevera kugadzirisa.Pamusoro pezvo, shinda yarastiki (filament), yakaderera elastic yarn (filament) uye shinda yakakura inogona zvakare kugadzirwa nekupisa kuseta maitiro akasanganiswa nemamwe emuviri kana mechanic mhedzisiro.
Mukuwedzera pakuvandudza kugadzikana kwedimensional, zvimwe zvinhu zvejira rinopisa rinewo shanduko dzinoenderana, dzakadai semvura inogadzirisa pfuma uye pilling resistance property inovandudzwa, uye mubato wacho wakanyanya kuoma;Iyo yekutsemuka kurebesa kweiyo thermoplastic fiber inodzikira nekuwedzera kwekupisa kwekuisa tension, asi simba rinochinja zvishoma.Kana tembiricha yekumisa yakanyanya, ese ari maviri anoderera zvakanyanya;Shanduko yezvivakwa zvekudhaya mushure mekupisa kupisa kunosiyana nemhando dzefiber.
