Chimiro chejira chii chinonzi spandex?
Spandex imhando ye polyurethane fiber.Nekuda kwekunaka kwayo, inozivikanwawo se elastic fiber, iyo yakashandiswa zvakanyanya mumachira embatya.Hunhu hukuru hwemucheka we spandex ndeiyi:(1) Kunyungudika kwe spandex kwakakwira zvakanyanya.Kazhinji, zvigadzirwa hazvishandise 100% polyurethane, uye kazhinji, 5% kusvika 30% polyurethane inosanganiswa mumucheka, zvichiita kuti pave nemhando dzakasiyana dzemachira espandex anozvirumbidza 15% kusvika 45% yekugadzikana kwekugadzikana. 2) Mucheka we spandex unowanzo gadzirwa neshinda inosanganiswa.Zvinoreva kuti spandex ndiyo musimboti uye mamwe mafiber (akadai senaironi, polyester, nezvimwewo) ndiwo cortex yekugadzira jira rekuvhara jira, iro rinozvirumbidza kuchinjika zvakanaka kumuviri uye ndiro rakanakira mbichana mbichana, isingapi pfungwa. pressure.
(3) Chitarisiko uye kupfekeka kwe spandex elastic jira riri padyo neayo ezvakaita sezvigadzirwa zvakaita sejira rayo rekunze rakavharwa.
Ndezvipi zvinopenya zvembatya zvakagadzirwa nespandex?
1. Kubatsira kukuru kwemucheka wespandex ndiko kunaka kwayo, iyo inogona kutambanudzwa 5 kusvika ku8 nguva pasina kuchembera.Spandex haigoni kurukwa yoga uye inowanzorukwa nezvimwe zvinhu mbishi.Zviri mukati me spandex zvinenge 3 kusvika ku10%, uye kuti mumucheka wekushambira unogona kusvika 20%.
2. Spandex fiber is a synthetic fiber ine yakakwira elongation panguva yekuzorora (kupfuura 400%), yakaderera modulus uye yakakwirira elastic kupora rate.Iri ndiro zita rekutengesa reChinese remulti-block polyurethane fiber, inozivikanwawo se elastic fiber.Spandex ine yakakwira elongation (500% kusvika 700%), yakaderera elastic modulus (200% elongation, 0.04 kusvika 0.12 g/denier) uye yakakwira elastic recovery rate (200% elongation, 95% kusvika 99%).Hunhu hwayo hwepanyama uye hwemagetsi hwakanyanya kufanana neaya echisikigo latex waya kunze kwekusimba kwayo kukuru.Inoshingirira kuparara kwemakemikari kupfuura sirika ye latex, uye ine mwero wekudzikama kwekushisa nekupfava kunosvika 200 ℃ kana kudarika.Mazhinji madhayi uye maajenti ekupedzisa anoshandiswa mukugadzira uye mafibhi echisikigo akakodzerawo kudhaya uye kupedzisa spandex.Spandex inoshingirira kudikitira, mvura yegungwa uye dzakasiyana siyana dzakaoma dzakaoma uye mazhinji ezuva.Ichapera zvakare nekuratidzwa kwenguva refu kuchiedza chezuva kana chlorine bleach, asi dhigirii rekudzima rinosiyana zvakanyanya nerudzi rwe spandex.Spandex ndeye polyurethane fiber.Nekuda kwekunakisisa kwayo, inozivikanwa zvakare se elastic fiber, yakashandiswa zvakanyanya mumachira embatya ane hunhu hwakadai sehunyoro hwepamusoro.Spandex jira rinonyanya kushandiswa mukugadzira matinji, zvipfeko zvemitambo, tambo dzekudzivirira uye soles.Mhando dzayo zvichienderana nezvinodiwa zvekushandisa, dzinogona kukamurwa kuita warp elastic jira, weft elastic jira uye warp uye weft bi-directional elastic jira.
Hunhu hweSpandex Fiber Fabric uye Kushandiswa kweSpandex
Spandex imhando ye polyurethane fiber.Nekuda kwekunaka kwayo, inozivikanwawo se elastic fiber, iyo yakashandiswa zvakanyanya mumachira embatya.
1. Hunhu hukuru hwemucheka we spandex fiber
(1) Iyo elasticity yespandex yakakwira zvakanyanya.Kazhinji, zvigadzirwa hazvishandise 100% polyurethane, uye kazhinji, 5% kusvika 30% polyurethane inosanganiswa mumucheka, zvichiita kuti pave nemhando dzakasiyana dzemachira espandex anozvirumbidza 15% kusvika 45% yekugadzikana kwekugadzikana.
(2) Mucheka wespandex unowanzo gadzirwa neshinda inoumbwa.Zvinoreva kuti spandex ndiyo musimboti uye mamwe mafiber (akadai senaironi, polyester, nezvimwewo) ndiwo cortex yekugadzira jira rekuvhara jira, iro rinozvirumbidza kuchinjika zvakanaka kumuviri uye ndiro rakanakira mbichana mbichana, isingapi pfungwa. pressure.
(3) Chitarisiko uye kupfekeka kwe spandex elastic jira riri padyo neayo ezvakaita sezvigadzirwa zvakaita sejira rayo rekunze rakavharwa.
2. Kushandiswa kwe spandex
(1) Spandex fiber inogona kushandiswa kugadzira zvipfeko zvinogona kutambanudzwa kuti zvisangane nekunyaradza zvinodiwa.Semuyenzaniso: Mbatya dzemitambo dzehunyanzvi, hembe dzekurovedzera muviri uye zvipfeko zvekurovedzera muviri, sutu yekudhivha, sutu yekugezera, masutu ekugezera emutambo, mbatya dzebasketball, bra necondole belt, ski pants, mbatya dzedisco, jini, bhurugwa remazuva ese, masokisi, zvinodziya makumbo, manapukeni. , bhurugwa rinobata, bhande, zvipfeko zvemukati, majumpsuits, spandex close-fitting clothes, mabhandeji anoshandiswa nevarume vanotamba ballet, hembe dzinodzivirira pakuvhiyiwa, hembe dzinodzivirira dzinoshandiswa nesupport units, maoko mapfupi ekuchovha bhasikoro, wrestling vest, sutu yekukwira chikepe, underwear. , zvipfeko zvekuita, zvipfeko zvemhando yepamusoro, brassiere, zvekushongedza kumba, micro-bead pillow, nezvimwe.
(2) Spandex haiwanzo shandiswa muzvipfeko zvakajairika.MuNorth America, inoshandiswa zvishoma pane zvipfeko zvevarume uye zvakanyanya pazvipfeko zvevakadzi.Nokuti zvipfeko zvevakadzi zvinodiwa kuti zvive pedyo nemuviri.Mukushandiswa, ichave yakasanganiswa nehuwandu hukuru hwemamwe mafiibhi akadai sekotoni uye polyester kuitira kuderedza kupenya kusvika kushoma.
