Kev lag luam textile tau ua haujlwm tas li ntawm qhov zoo, kom muaj nuj nqis thiab ua haujlwm ntawm cov ntaub. Txhim kho lawv cov kev ua tau zoo thiab tau txais cov khoom siv hluavtaws polyamide tau dhau los ua ib hom kev hloov pauv hauv cheeb tsam no. Yog li ntawd, nyob rau hauv lub 30s ntawm lub xyoo pua 20th nyob rau hauv Amelikas, W. Carothers, tus thawj kws tshuaj ntawm lub tuam txhab DuPont, yog thawj zaug rau synthesize ib 66-monopolymer, raws li tau zoo raws li ib tug hluavtaws polyamide, nylon, tau txais. Cov ntaub yog tsis tsim nyog hu ua "synthetic silk". Nws zoo kawg nkaus ua raws li cov ntaub ntuj tsim, muaj lub zog siab, elasticity thiab hnav tsis kam.

Ua raws li nylon, lycra, polyester thiab lwm cov fibers zoo sib xws. Lub sijhawm ntawm kev siv cov khoom siv hluavtaws tau pib. Xyoo 1939, DuPont tau qhib thawj lub Hoobkas rau kev tsim cov xov thiab cov ntaub los ntawm polyamide-6, 6. Tom qab xyoo 1940, cov tuam txhab tsim cov nylon kuj tau pib tsim hauv Ltalis thiab Tebchaws Askiv. Npuag keeb kwmtau siv los ua parachutes, nuv ntses nets, thiab tom qab ntawd tau siv dav hauv kev tsim cov khaub ncaws ntau yam.

Qhov txuj ci tseem ceeb fiber ntau, thawj zaug tau tshaj tawm xyoo 1940 ntawm New York Ntiaj Teb Kev Ncaj Ncees hauv daim ntawv nylon stockings, ua rau muaj kev sib tw loj heev. Nyob rau thawj hnub ntawm lawv qhov tshwm sim hauv Asmeskas, ntau dua 72 txhiab khub tau muag. Ntau lab tus poj niam txaus siab rau qhov zoo tshaj plaws novelty, uas tsis mus rau hauv unsightly folds thiab wrinkles. Nws cov tswv tau txais ntau qhov kev xav tshiab uas cov ntaub tshiab tau muab rau lawv. 100% nylon khawm ob txhais ceg zoo nkauj thiab tawm lub siab zoo. Kev muaj koob meej thiab kev xav tau nce mus rau qhov tsis txaus ntseeg, uas hloov pauv kev txhim kho ntxiv ntawm kev lag luam hosiery.

Polyamide-6, 6 threads tau siv dav hauv kev tsim cov khoom lag luam thiab kev lag luam textile. Qhov no polyamide hluavtaws fiber ntau, muaj zog, elastic, antistatic, resistant rau dabtsi yog khoov, puas thiab feem ntau cov tshuaj, yog tam sim no siv nyob rau hauv txhua lub tsev. Qhov tseem ceeb ntawm kev tsim nylon tau raug qhuas thoob plaws ntiaj teb, thiab nws tau raug hu ua ib qho tseem ceeb tshaj plaws kev tshawb pom ntawm lub xyoo pua 20th.

Ntawm tag nrho cov polyamide fibers, nylon yog suav tias yog cov khoom kim tshaj plaws thiab kim. Cov ntaub, cov khoom uas tau muab tso rau hauv cov txheej txheem ntawm nws cov khoom ntawm qib molecular, qiv nws tus kheej zoo rau dyeing, tso cai rau koj los tsim cov xim zoo kawg. Cov polyamide no tuaj yeem siv los ua ib qho ntawm cov khoom lag luam lossis hauv nws daim ntawv ntshiab.

Hnub no nws nyuaj rau xav txog thaj chaw uas tsis siv nylon. Cov ntaub yog siv los tsim cov knitwear, cov khoom ua si thiab cov khaub ncaws, tsho, swimwear, tsev textiles. Cov neeg tsim khoom siv nylon los ua cov khoom siv rau kev tsim cov kaus, lub hnab, cov koom haum, cov tub rog hnav khaub ncaws, lub cev armor, parachutes, lifejackets.

Cov polyamide no tau siv dav hauv kev tsim cov ntaub pua plag rau ntau chav, tsis hais lawv txoj haujlwm. Nws cov khoom, xws li elasticity thiab tawg tsis kam, tso cai rau nws siv rau kev tsim cov txheej txheej txiav. Txhawm rau txhim kho kev ua tau zoo, tshwj xeeb los tiv thaiv zoo li qub thiab yooj yim ntawm kev saib xyuas, cov fiber ntau tau kho nrog cov tshuaj tshwj xeeb.

Ib yam khoom siv hauv ntiaj teb yog nylon. Cov ntaub tau txais txiaj ntsig zoo heev vim nws cov khoom zoo heev. Nws tsis wrinkle, yooj yim los ntxuav thiab khaws nws cov tsos rau lub sijhawm ntev.
