Qhov loj tshaj plaws ntawm Lycra stretch npuag yog siab elasticity, hu ua elastic fiber, uas tuaj yeem ncav cuag 4-7 npaug ntawm qhov ntev. Yuav luag txhua yam kev ua kis las hauv ntiaj teb niaj hnub no siv spandex. Tshwj xeeb tshaj yog gym suits thiab swimsuits. Lycra npuag yog cov ntaub ua los ntawm spandex fiber (luv rau Spandex polyurethane fiber), uas tseem hu ua "rub thav duab" (lub suab lus Cantonese ntawm Lycra) hauv thaj chaw Cantonese.

Hauv Tebchaws Meskas, qee zaum hu ua "spandex daim ntaub" ncaj qha. "Lycra" yog transliteration ntawm lus Askiv lo lus LYCRA. Nws tau ua tiav kev tshawb fawb los ntawm Bayer hauv lub teb chaws Yelemees xyoo 1937, thiab DuPont pib tsim hauv xyoo 1959. Nws yog ib lub npe lag luam ntawm DuPont spandex fiber ntau, uas tuaj yeem txhim kho cov elasticity thiab extensibility ntawm cov ntaub, thiab qhov zoo rov qab ntawm spandex tom qab ncab yog nws. qhov zoo tshaj plaws. Qhov txawv ntawm cov tsoos elastic fiber ntau yog tias nws tuaj yeem ncav cuag 500% thiab tuaj yeem rov qab los rau nws qhov qub.

Hauv lwm lo lus, cov fiber ntau no tuaj yeem ncab tau yooj yim heev, tab sis nws tuaj yeem lo rau saum npoo ntawm tib neeg lub cev tom qab rov qab los, thiab lub zog tswj ntawm tib neeg lub cev yog me me heev. Lycra fiber tuaj yeem siv nrog txhua yam ntaub. Nws yog hu ua "phooj ywg" fiber ntau, suav nrog cov ntaub plaub, hemp, txhob lo lo ntxhuav thiab paj rwb, txhawm rau ua kom lub ntsej muag zoo, elastic thiab xoob ntawm cov ntaub, thiab nws xav tias hloov tau yooj yim dua thaum tsiv. Ntxiv mus, Lycra yog txawv ntawm feem ntau cov xov paj spandex. Nws muaj cov qauv tshuaj tshwj xeeb thiab yuav tsis loj hlob tuaj pwm nyob rau hauv qhov chaw ntub dej thiab cua sov kaw tom qab ntub dej. Nws cov khoom zoo tau lees paub los ntawm cov phooj ywg. Tam sim no, tsuav yog cov khaub ncaws uas siv Lycra yuav dai nrog daim duab peb sab, daim ntawv no kuj tau dhau los ua lub cim ntawm qhov zoo.

Lycra stretch fabrics yuav tsis ntsws. Lycra yog hu ua "phooj ywg" fiber ntau, tsis yog vim nws tuaj yeem ua tiav nrog cov khoom siv ntuj tsim thiab tib neeg tsim, tab sis kuj tuaj yeem ua rau kom muaj kev nplij siab ntawm cov ntaub lossis khaub ncaws, kev nkag siab ntawm kev txwv, thiab kev ywj pheej ntawm kev txav thiab kev pabcuam. lub neej. Qhov zoo ntawm Lycra stretch npuag 1. Yooj yim heev

Nws tuaj yeem txhim kho elasticity ntawm cov ntaub. Nws tuaj yeem siv ua ke nrog ntau hom fibers sib txawv, txawm tias nws yog ntuj lossis tib neeg tsim fibers, nws yuav tsis hloov qhov tsos thiab kev ntxhib los mos ntawm cov ntaub. Piv txwv li, wool + Lycra fabrics tsis yog tsuas yog elastic, tab sis kuj zoo dua haum, zoo tuav, drape thiab hnav tom qab ntxuav; paj rwb + Lycra tsis tsuas yog muaj qhov zoo ntawm paj rwb fiber ntau kev nplij siab thiab breathability, tab sis kuj siv rau hauv cov paj rwb Nws tsis muaj cov yam ntxwv zoo elasticity thiab tsis yooj yim rau deform, uas ua rau cov ntaub ntau haum, haum, mos thiab xis. Lycra tuaj yeem ntxiv qhov tshwj xeeb zoo rau cov khaub ncaws: kev nplij siab zoo, kev ywj pheej ntawm kev txav mus los thiab kev tuav lub cev ntev.

2. Kev siv dav dav

Lycra tuaj yeem siv rau paj rwb knitted fabrics, ob-sided wool fabrics, txhob lo lo ntxhuav poplin, nylon fabrics thiab txawv paj rwb ntaub.

3. Kev nplij siab ntawm Lycra

Nyob rau hauv xyoo tas los no, cov neeg uas nyiam zam muaj kev nyuaj siab los ntawm kev tsis khoom thiab kev sib tw ntawm lub nroog. Lawv tsis xav tau cov khaub ncaws uas nrog lawv txhua hnub. Lawv yuav tsum tau koom ua ke nrog kev nplij siab thaum tuav cov khaub ncaws kom zoo. Lycra cov khaub ncaws muaj cov yam ntxwv ntawm kev sib haum xeeb thiab kev ywj pheej, uas ua tau raws li cov kev xav tau ntawm cov neeg nyob hauv lub neej niaj hnub rau khaub ncaws.

Lycra fiber ntau thiab nws daim ntawv thov

Lycra yog nyob rau hauv daim ntawv ntawm matt dawb, translucent los yog pob tshab filaments nrog ib tug fineness ntawm 11 dtex-1880 dtex. Lycra silk ntawm ntau yam finenesses yog siv nyob rau hauv: pob tshab stockings; ncig knitwear (cov ris tsho hauv qab, ncaws pob); txhais ceg thom khwm; nqaim siv duav; warp knitted fabrics rau poj niam lub ris tsho hauv qab thiab swimwear; cov khoom siv kho mob (puab daim, Bandages, thiab lwm yam); khau, thiab lwm yam.
