Sei The Dispersion Fastness Yakashata?

Kuparadzira dhayi kunonyanya kushandisa tembiricha yepamusoro uye kudzvanywa kwepamusoro pakudhaya mapolyester fiber.Kunyange zvazvo mamorekuru edhayi anoparadzira ari madiki, haagone kuvimbisa kuti mamorekuru ese edhayi anopinda mufayibha panguva yekudhayiwa.Mamwe madhayi anoparadzira anonamatira kune fiber pamusoro, zvichikonzera kushanya kwakashata.Inoshandiswa kuparadza mamorekuru edhayi asina kupinda mufiber, kuvandudza kukurumidza, nekuvandudza mumvuri.

Kuparadzira dhayi yemachira epolyester, kunyanya mumavara epakati uye akasviba, kuti abvise zvizere mavara anoyangarara uye maoligomers akasara pamusoro pemucheka uye nekuvandudza kukurumidza kwekudhaya, zvinowanzodikanwa kuita kuderedza kuchenesa mushure mekudhaya.

Mucheka wakasanganiswa kazhinji unoreva shinda yakagadzirwa nezvikamu zviviri kana kupfuura zvakasanganiswa, saka jira iri rine zvakanakira zvinhu zviviri izvi.Uye nekugadzirisa chikamu chechikamu, mamwe maitiro eimwe yezvikamu anogona kuwanikwa.

Kusanganisa kunowanzo reva staple fiber blending, kureva kuti, mafiber maviri ezvikamu zvakasiyana anosanganiswa pamwe chete muchimiro chestaple fibers.Semuenzaniso: polyester-cotton blended fabric, inowanzonzi T / C, CVC.T/R, etc. Yakarukwa nemusanganiswa wepolyester staple fiber uye fiber yekotoni kana fiber yakagadzirwa nevanhu.Zvakanakira zvaro ndezvekuti: ine chitarisiko uye kunzwa kwese-donje jira, inonetesa kemikari fiber luster uye kemikari fiber inonzwa yemucheka wepolyester, uye inovandudza mwero.

Kuvandudzwa kwekukurumidza kwemavara, nekuti jira repolyester rine ruvara pakupisa kwepamusoro, kukurumidza kweruvara kwakakwira kupfuura kwekotoni, saka kukurumidza kweruvara rwepolyester-donje rakasanganiswa jira rinovandudzwa zvakare kana richienzaniswa nekotoni.

Nekudaro, kuti uvandudze kutsanya kwemavara emachira e-polyester-donje, kuchenesa kuderedzwa (inonzi R / C) kunofanirwa kuitwa, uye mushure mekurapa mushure mekupisa kwekushisa kwekudhaya uye kupararira.Iyo yakanakira kutsanya kwemavara inogona kuwanikwa chete mushure mekudzikisa uye kuchenesa.

Staple fiber blending inobvumira hunhu hwechikamu chimwe nechimwe kuti chionekwe zvakaenzana.Saizvozvo, kumwe kusanganiswa kwechikamu kunogonawo kutamba zvakanakira kusangana nezvimwe zvinoshanda kana kunyaradza kana hupfumi zvinodiwa.Zvisinei, machira akasanganiswa epolyester-cotton anoparadzirwa uye anodhayiwa pakupisa kwakanyanya.Pakati, nekuda kwekusanganiswa kwekotoni kana rayon fiber, uye tembiricha yekudhaya haigone kukwira kupfuura tembiricha yejira repolyester.Nekudaro, machira epolyester-donje kana polyester-donje rayon machira, pasi pekurudziro yealkali yakasimba kana sodium hydroxide, ichaita kuti simba refiber kana kubvarura simba ridonhe zvakanyanya, uye zvakaoma kuwana kunaka kwechigadzirwa mune zvinotevera zvinongedzo.

Iyo yekupisa yekutama maitiro ekuparadzira dhayi inogona kutsanangurwa sezvinotevera:

1. Mukuita kwekushisa kwekushisa kwepamusoro, chimiro chepolyester fiber chinosunungurwa, dhayi inoparadzira inopararira kubva pamusoro pefiber ichipinda mukati mefiber, uye inonyanya kushanda papolyester fiber nehydrogen bond, dipole attraction uye van der. Waals force.

2. Kana iyo fiber yakadhayiwa ichiiswa mukupisa kupisa kwakanyanya, simba rekupisa rinopa simba rekuita repamusoro kune polyester refu cheni, iyo inowedzera kuzunguzika kwecheni ye molecular, uye microstructure ye fiber inozorora zvakare, zvichikonzera kubatana pakati. mamwe mamorekuru edhayi uye cheni yepolyester Yapera simba.Naizvozvo, mamwe mamorekuru edhayi ane simba rekuita repamusoro uye dhigirii repamusoro rekuzvimiririra anotama kubva mukati mefiber kuenda kune faibha pamusoro pedhizaini ine yakasununguka chimiro, inosanganisa nefiber pamusoro kuti igadzire dhayi repamusoro.

3. Panguva yekunyorova kutsanya bvunzo.Mavara epamusoro asina kusungirirwa zvakasimba, uye dhayi anonamatira kune chikamu chinonamatira chekotoni, achasiya nyore nyore fiber kupinda mukugadzirisa uye kusvibisa jira jena;kana kunamatira zvakananga kune bvunzo jira jena nekukwesha, zvichiratidza kunyorova nekukurumidza uye kukwesha kwechigadzirwa chakadhayiwa kutsanya kunoderera.
