Polyester-donjejira rakasanganiswarudzi rwakagadzirwa muChina mukutanga kwema1960.Iyi fiber yakaoma, yakatsetseka, inokurumidza kuomesa uye inopfeka isingachinji.Inofarirwa pakati pevatengi vakawanda.Mucheka wepolester-donje unoreva jira rakasanganiswa repolyester fiber uye fiber yekotoni, iyo isingangoratidzi chimiro chepolyester asiwo ine zvakanakira jira rekotoni.
Performance maitiro epolyester:
Sechinhu chitsva chakasiyaniswa fiber zvinhu,polyester fiberine zvimiro zvesimba repamusoro, hombe modulus, kurebesa kudiki uye yakanaka dimensional kugadzikana, etc. Iine yakapfava magadzirirwo, yakanaka cohesive simba, zvinyoro nyoro uye imwe core warming effect.Kunwa kwemwando kwepolyester kwakashata.Uye pasi pezvakajairwa mamiriro emuchadenga, mwando unowanikwa zvakare ungangoita 0.4%.Saka zvinopisa uye zvakapfava kupfeka jira rakachena repolyester.Asi machira epolyester ari nyore kushambidza uye kukurumidza kuomeswa, iyo ine zita rakanaka re "kushambidza uye kupfeka".Polyester ine yakakwira modulus, inongotora yechipiri kune hemp fiber, uye ine elasticity yakanaka.Naizvozvo, jira repolyester rakaoma uye rinopesana nekuwunyana.Yakagadzikana muhukuru uye ine chimiro chakanaka chekuchengetedza.Polyester ine yakanaka abrasive kuramba, iri padyo nenylon chete.Asi inosungirwa kupora uye mabhora haasi nyore kudonha.
Kuita maitiro ekotoni:
Iyo yemuchinjikwa chikamu chekotoni fiber haina kutenderedza chiuno chine midplane mukati.Kumucheto kwelongitudinal kwakavharwa tubular masero, akakora pakati uye akatetepa kumativi ose maviri.Natural crimp ndiyo yakakosha morphological maitiro ekotoni fiber.Cotton faibha inoshingirira alkali asi kwete asidi.Ine kunwa kwakasimba.Pasi pemamiriro akajairwa, kunyorova kwekotoni fiber ndeye 7 ~ 8%.Mushure mekuita kwemaawa masere pakupisa kwe100 ℃, simba rayo harina kukanganiswa.Pa150 ℃, fiber yekotoni ichaora, uye pa320 ℃, ichapisa.Cotton faibha ine yakaderera yakananga kuramba, izvo zvisiri nyore kugadzira static magetsi mukugadzirisa nekushandisa.
Kukwirira kwepolyester-cotton blends:
Polyester-cotton blended jira haisi kungosimbisa chimiro chepolyester, asiwo ine mukana wekotoni.Pasi pemamiriro akaoma uye emvura, ine elasticity yakanaka, yakanaka abrasive resistance, saizi yakagadzikana uye kuderera kudiki.Yakaoma, haisi nyore kucheka, iri nyore kugeza uye nekukurumidza kuomesa.Iine kupenya kwakajeka.Kunzwa kweruoko kwakatsetseka, kwakaoma uye elastic.Mushure mekupukuta ruoko, iyo crease haisi pachena uye inopora nekukurumidza.Asi zvakare ine zvikanganiso zvakafanana nekemikari fiber iyo chikamu chekukwesha chiri nyore kubhururuka uye kupora.Polyester-donje rakasanganiswa jira rine gobvu uye rakapfava ruoko.Zvinonyanya kusununguka kupfeka.Inogona kuchengetedza chimiro chayo mushure mekugezwa kakawanda pasina creasing kana kuderera.
Polyester-donje uye Cotton-polyester:
Polyester-donje uye donje-polyester marudzi maviri emachira akasiyana.
1.Polyester-cotton (TC) machira anotsanangurwa seanopfuura 50% polyester uye pasi pe50% yekotoni.
Zvakanakira: Kupenya kunopenya kupfuura jira redonje chairo.Mubato wakatsetseka, wakaoma uye wakaoma.Hazvina kugadzikana.Uye iyo yakawanda yepolyester, zvishoma zvingaita kuti jira racho riite kuunyana.
Zvakaipa: Chimiro cheganda chakashata kupfuura jira redonje rakachena.Hazvina kunyanya kugadzikana kupfeka pane jira rakachena rekotoni.
2.Cotton-polyester (CVC) jira rinongova reverse, iro rinotsanangurwa serinopfuura 50% yekotoni uye isingasviki 50% polyester.
Zvakanakira: Kupenya kunopenya zvishoma pane jira redonje rakachena.Musoro wejira wakatsetseka uye wakachena pasina tsvina yakaoma kana tsvina.Mubato wakatsetseka uye wakaoma.Inonyanya kurwisa kuunyana kupfuura jira redonje rakachena.
Zvakaipa: Chimiro cheganda chakashata kupfuura jira redonje rakachena.Hazvina kunyanya kugadzikana kupfeka pane jira rakachena rekotoni.
