Daim ntawv thov ntawm ib tug elastomeric yarn kom zoo ntawm cov ntaub

Cov khoom siv dag zog, cov khoom siv roj ntsha, thiab cov khoom siv hluav taws xob tsis muaj additives, muaj txo cov elasticity thiab tsis ncab txhua. Khoom los ntawm lawv crumple, stretch, nws yog yuav luag tsis rov qab los lawv qub tsos. Tsis tas li ntawd, nyob rau hauv xws li khaub ncaws nws tsis yog yooj yim heev tsiv. Los txhim kho qhov kev ua tiav ntawm cov ntaub, hluavtaws fiber - elastane ntxiv rau lawv cov khoom xyaw. Hauv Canada thiab hauv Teb Chaws Asmeskas, nws yog hu ua spandex, uas txhais tau tias "ncab".

Los ntawm keeb kwm ntawm keeb kwm

Rau thawj thawj zaug, ib qho hluavtaws elastomeric xov tau tshwm sim nyob rau hauv kev lig fifties ntawm lub xyoo dhau los ua tsaug rau lub tswv yim ntawm American tus kws tshawb fawb J. Shivers, ua haujlwm ntawm DuPont.

Tom qab, lub cim "Lycra" los ntawm Invista, ib tug tswv cuab ntawm ib lub koom haum Ameslikas Amelikas, tau sau npe.

Nyob rau hauv Nyiv, cov ntaub ntawv los ntawm xov elastomer yog ua nyob rau hauv hom "Dorlastan".

Khoom siv lus

Elastan yog ib lub tswv yim thiab ci ntsa iab, uas lawv xaws lub teeb, nyiam khaub ncaws. Nws rushes rau ib lub sij hawm ntev thiab tsis crumple. Qhov zoo tshaj plaws, ua tsaug rau cov khoom uas tau muaj qhov koob meej, yog kev siab zog. Qhov ntev ntawm elastane fibers tau nce ntau txog 5-8 zaug.

Ntxiv nrog rau elasticity, spandex muaj ib tug xov tooj ntawm cov khoom tseem ceeb:

• Elasticity - tom qab ncab rov qab los rau nws thawj daim ntawv.
• Durability - tsis ntshai ntawm loads, tsis hloov cov yam ntxwv hauv tus dej.
• Subtlety - thickness ntawm elastomeric threads yog tsawg, thiaj li hais tias lawv yuav woven mus rau hauv tej ntaub.
• Softness - cov khoom nrog ntxiv ntawm elastane yog saj zawg zog, yooj yim draped nrog soft folds.
• Lightness - kev siv ntawm cov khoom siv suab tsis hloov tag nrho qhov hnyav ntawm cov canvas.

Elastomeric xov nyob rau hauv cov nyob tus yee ntawm hluavtaws thiab ntuj fabrics ua rau nws tau txais breathable, elastic, xis thiab qab ntxiag rau cov ntaub ntawv kov. Cov khaub ncaws uas ua los ntawm cov ntaub npog no yeej tsis muaj ntsws ntswj, tuav nws qhov muag pom ntev ntev, tsis hnav thiab tsis khawm qhov taw.

Elastane (elastomeric) filaments tsim ci, dawb, opaque lossis pob tshab. Lub hauv paus muaj oval, puag ncig lossis dumbbell fibers ntawm Cross section.

Daim ntawv thov ntawm cov khoom ua los ntawm elastomeric yarns

Feem ntau, cov elastomer muaj nyob rau hauv daim ntawv ntawm threads mob ib ncig ntawm cov lus. Feem ntau, paj rwb, ntaub pua chaw, cov ntaub ntawv viscose lossis polyamide muab ntxiv rau nws, vim tias cov khoom siv polyurethane tsis yog siv hauv kev xyaum. Qhov no ua ke ua kom lub zog thiab elasticity ntawm cov khoom tiav, ua rau lawv zoo li ntau txaus nyiam. Qhov no yog vim li cas rau kev siv ib qho xov elastomer rau beadwork. Nyob rau tib lub sij hawm, hnav tsis ua hauj lwm. Ris tsho zoo dua rau ib tus neeg, tsis ua rau mob voos thiab qhuav ntawm daim tawv nqaij.

Qhov tsis muaj spandex yog ib qho instability rau tus cawv ntawm ultraviolet thiab dej nrog ib tug high school cov ntsiab lus ntawm chlorine. Tsis tas li ntawd, threads nrog elastane tuaj yeem ua ib qho kev ua xua, ces thaum muag nws tseem ceeb txaus siab rau lub cev muaj pes tsawg leeg.

Khaub ncaws nrog ntxiv ntawm elastomeric fibers

Nws pom zoo kom ntxiv 5 mus rau 15% elastane rau cov khoom pib. Feem ntau nrov ua ke ntawm polyurethane fibers nrog viscose - los ntawm cov ua ke ua ke, lawv ua ib qho kev ua kis las thiab khaub ncaws rau lub neej txhua hnub. Tsis tas li ntawd, los ntawm cov kua hluav taws xob nrog elastane ua nruj nreem rau cov tog hauv cocktail thiab kev ua koob tsheej.

Ua rau cov feem pua ntawm elastomer mus rau 20-30% muab cov khoom siv nrog kev hnyav ntxiv. Feem ntau ntawm sportswear, swimsuits, stockings thiab pantyhose yog sewn los ntawm nws.

Rau festive outfits thiab carnival dluab nyob rau hauv lub ntaub dhau li Lycra muaj Lurex. Elastomer yarns (pictured nram qab) kuj tau siv los ua cov ris tsho hnav ris tsho - ntxiv rau cotone, li 5% ntawm polyurethane filaments ntxiv.

Lub hero ntawm "Kab laug sab-txiv neej" thaum lub sij hawm ntawm filming tau hnav ntau tshaj li ib tug xws li nplua. Thiab cov zaj duab xis yog tsim nyog nws, thiab tag nrho cov ua tsaug rau cov khoom sib txuas. Lawv tau los ua lub ntiaj teb kev hnav khaub ncaws rau kev ua lag luam, kev ua si - txhua qhov chaw, qhov uas nws yuav tsum tau nrhiav kev ci ntsa iab thiab tshiab.

Muab kev saib xyuas ntawm cov khaub ncaws

Cov cai ntawm kev tu kom tiav cov khoom yog nyob ntawm seb cov ntaub ntawv muaj li cas hauv elastane. Cov lus pom zoo muaj nyob rau ntawm daim ntawv lo:

1. Ntxhua khaub ncaws los ntxuav muag lossis ntxuav tes. Dej kub yuav tsum qis dua 40 ° C.
2. Polyurethane yarns muaj peev xwm tawg, yog li thaum muab cov ris tsho, tsis txhob xav twv nws.
3. "Phaum" txhuam thiab tshuaj dawb ua kom sai sai, tab sis lawv yuav tsum raug tso tseg.
4. Txhawm kom cov duab, qhuav cov khoom nyob rau hauv ib txoj hauj lwm tav toj.
5. Nws yog qhov pom zoo kom hlau cov ntaub ntawm kub txog 150 ° C.

Xam ntawm lycra nyob rau hauv cov ntaub txawm nyob rau hauv ib tug me me tau tso cai rau ib tug zoo hloov nyob rau hauv qhov zoo ntawm cov khoom tiav. Ris tsho yuav tsis zoo nkauj thiab zoo heev, tab sis kuj check, vim yog lub elasticity muab los ntawm elastomeric xov. Tus nqi ntawm elastane khoom ncaj qha yog nyob ntawm seb qhov khoom ntawm no cov khoom nyob rau hauv cov lus qhia ntawm cov ntaub siv, thiab cov feem pua ntawm lwm cov ntaub ntawv ntxiv: cottons, lycra, polyurethane fibers, thiab lwm yam.
