Elastane (Lycra, spandex) yog polyurethane hluavtaws cov khoom zoo sib xws los ntawm cov khoom ntawm roj hmab roj hmab. Hauv nws cov ntawv ntshiab, nws yuav luag tsis siv nyob rau hauv kev tsim khoom, nws yog ntxiv rau lwm lub ntuj lossis hluavtaws fibers. Spandex yog ib feem ntawm ntau hom kev sib xyaw hom kev sib xyaw: viscose, xaws, paj rwb, cov paj rwb, silk. Lub xub ntiag ntawm nws nyob rau hauv cov ntaub ntawv no ua rau lawv elastic.
Qhov ntau Elastan hauv cov canvas, qhov yooj yim dua nws yog ncab.
Tshwj xeeb yog tsim tau zoo tsim nws tus kheej hauv lub tshuab xaws ua ke ua ke sib zog ua ke thiab viscose - cov ntaub so ntswg no yog qhov zoo nkauj, muag thiab qab ntxiag rau kov.
Zaj liv xwm
Thawj qhov kev sim ntawm kev tsim ntawm Elastan tau ua los ntawm Dupont nyob rau xyoo 1946, thiab nws tus neeg ua tus tsim tawm yog Joseph Chulls, tus kws tshawb fawb tshuaj lom neeg. Cov ntaub ntawv no yog Ameslikas ua rau cov suab paj nruag lawj thiab corsets. Ib me ntsis tom qab pib siv rau hauv kev tsim cov khoom lag luam ntim khoom. Hauv 60s ntawm lub xyoo pua xeem, cov ntaub so ntswg no tau txais kev pom zoo ntawm cov neeg ntaus pob ncaws pob. Nyob rau hauv lub lig 70s, Lycra twb paub thoob ntiaj teb, nws tau nquag siv hauv kev tsim cov khaub ncaws thiab khoom siv.Muaj pes tsawg leeg thiab cov khoom
Elastane yog sigled polyurethane, nws muaj cov ntu hloov tau thiab cov leeg ua kom nruj. Ntu yog kev sib cuam tshuam los ntawm Bundles ("choj"), uas tiv thaiv cov fibers los ntawm kev tawg thaum ncab.
Ntawm cov ntau yam ntawm Spandex, ob hom yog nrov tshaj: ob-seem thiab plaub-seem. Ob-seem seem yog ncab rau hauv ib qho kev taw qhia, lossis hauv qhov dav, lossis ntev. Plaub-seem spandex, ntsig txog, ncab ob qho tib si hauv qhov dav, thiab qhov ntev.
Cov ntaub hauv lub nroog Lycra yog tam sim no muaj ntau lub zog zoo.:
- Zoo ncab: xov hluav taws xob 6-8 lub sij hawm.
- Elasticity: Tom qab ncab, cov canvas rov qab los rau tus thawj qauv.
- Kev nqus tau cov pa tau yooj yim: cov ntaub, uas suav nrog lub Lycra, breathable, nws "ua pa", lub cev yooj yim nyob hauv qab nws.
- Hnav Kuj: Spandex Fibers Qhia rau nws ua rau nws ruaj thiab ruaj, cov hnav tsis kam ntawm xws li Canvase nce mus rau 2 zaug.
- Yooj yim thiab subtlety. Lycra zaj xov yog me me, cov ntaub ntawm nws yog qhov zoo thiab yuav luag yam hnyav.
- Kuj rau cov teebmeem ntawm dej thiab lub hnub: tsis ploj, tsis hloov cov xim tom qab ntxuav thiab ziab.
- Kev tswj hwm: Elastane npuag tsis mloog thiab tsis yog deformed tom qab lub sijhawm ntev ntawm kev ua haujlwm.
- Qhov ceev faj: Zoo li qhov ntsuas ntom ntom rau 1.3 G / cm3, uas muab cov khoom siv ntawm ncab.

Kev tsim
Elastic ntaub tau tuaj yeem ua los ntawm plaub txoj kev:
- tshuaj lom neeg (kev tshaj lij) tsim;
- cov txheej txheem qhuav ntawm txoj kev sib sau los ntawm kev daws teeb meem;
- ib txoj kev ntub ntawm kev sib sau ua ke los ntawm kev daws teeb meem;
- Cov koob txhaj tshuaj (extrusion) los ntawm ob yaj ntawm cov khoom siv polymer.
Daim Ntawv Thov thiab Kev Saib Xyuas
Elastane ua ib feem ntawm cov ntaub so ntswg sib xyaw yog siv rau cov khaub ncaws ntau lawm rau kev ua si thiab seev cev (Trico, luv luv, leggings). Los ntawm ntom spandex xaws khaub ncaws rau cov neeg koom nrog kev caij ski, sib sau. Tsis tas li, cov kev nyiam yog siv rau hauv kev tsim cov ua luam dej thiab smelters. Cov canvas nrog Elastane du thiab ci, nws yog qhov zoo tagnrho rau kev txiav tawm ntawm Carnival thiab cov cim ntawm xws li Canvase kuj muaj xws li ib qho xov dab tsi ci iab. Cov. Kev tsim cov poj niam nruj thiab leggings yog lwm qhov kev taw qhia uas elastane siv. Spandex muaj cov paj rwb yog siv hauv kev tsim cov khoom saum, mascas thiab t-shirts. Ncab cov ris tsho, txhua yam thiab luv nqi kuj xaws tsis tau los ntawm cov ntaub npuag nrog ntxiv ntawm Spandex.
Cov kev cai saib xyuas:
- Ntxuav tes ntxuav hauv dej kub nrog kev siv cov muag muag muag hmoov rau cov ntaub so ntswg nyias, tig tau yooj yim yam tsis muaj suab nrov;
- Tshuab ntxuav ntawm "phau ntawv ntxuav" lossis "hom" hom nrog dej kub txog rau 40 degrees, tig tsis ntau tshaj li 400 qib;
- Lwv tawm Elastane ua raws nyias los ntawm tej yam dawb;
- Nws yog txwv tsis pub siv cov tshuab ziab khaub ncaws, stains thiab tshuaj dawb;
- Kom qhuav - ntawm qhov chaw du hauv daim ntawv polished, tsis muaj hnub ci ntsa iab;
- ironing hauv "lo lo ntxhuav" lossis "me me";
- Koj tsis tuaj yeem khaws qhov khoom ntawm cov kev nyiam ntev ntev hauv daim ntawv ncab (ntawm cov khuam khuam khawb ncaws-lub xub pwg).
Yuav ua li cas txiav txim siab txog Lwm Yam Loj Loj yog dab tsi?
Tshawb xyuas cov ntawv sau kom zoo rau ntawm cov khoom, cov cim ntawm cov khoom yuav tsum tau qhia. Txhawm rau kom paub tseeb tias Lycra yog qhov tseeb nyob rau hauv cov canvas, sim ncab qhov khoom, thiab tom qab ntawd cia mus. Yog tias cov canvas tau lees txais nws daim qauv qub, tom qab ntawd Spandex yog ib feem ntawm cov khoom siv Cov.
