Dab tsi tau pib ua ib feem ntawm kev daws teeb meem los pab txhim kho cov tub ntxhais hluas hauv nroog hauv lub cev lub cev hauv xyoo 1950s sprouted rau hauv tag nrho kev lag luam mob siab rau kev tsim cov nyom nyom.
Ford Foundation's Education Facilities Laboratory, koom tes nrog Monsanto Industries thiab Chemstrand, txhawb kev siv cov ntaub pua tsev hluavtaws hauv tsev kawm ntawv. Los ntawm 1962 mus txog 1966, Lub Creative Group, Chemstrand lub koom haum tshawb fawb, tau sim cov hluavtaws turf ntaub pua plag rau nplaim taws, dej ntws tawm thiab ua haujlwm, thiab ua haujlwm ntev ntawm ko taw traction.
Thawj qhov loj hluavtaws nyom teeb tsa tau tshwm sim hauv 1964 ntawm Moses Brown Tsev Kawm Ntawv hauv Providence, Rhode Island. Cov nyom tau raug hu ua "Chemgrass."
Xyoo 1965 Houston's Astrodome yog qhov xav tau ntawm qhov chaw ua si zoo ib yam li ib puag ncig tsis tau tso cai rau qhov chaw zoo rau kev loj hlob ntawm cov nyom. Hloov chaw feem ntau coated nrog cov xim ntsuab ntawm cov av thiab thaj tsam ntawm cov nyom, Astrodome tus kws txiav txim plaub Hofheinz tau sab laj Monsanto txog kev txhim kho Chemgrass.
Pab Koomtes Major League Baseball, Houston Astros, tau pib lawv lub caij xyoo 1966 pov pob thiab tsoo lub tsev khiav saum Chemgrass, rov hu ua "Astroturf," lub npe tsev neeg paub ntau ntawm Asmeskas niaj hnub no. Tsim los ntawm James M. Faria thiab Robert T. Wright ntawm Lub Tuam Txhab Chemstrand, Astroturf thawj tiam hluavtaws nyom showcased tightly curled nylon fibers woven rau hauv ib tug npuas backing.
Daim Ntawv Pov Thawj patent tau tshaj tawm rau cov khoom siv dag zog thaum Lub Xya Hli 25, 1967.
Tom qab Astrodome txoj kev vam meej, Indiana State University tau teeb tsa cov nyom dag rau thawj qhov chaw ua si sab nraum zoov hauv xyoo 1967.
Artificial turf tau dhau los ua qhov kev vam meej uas txuas ntxiv nce qeeb tab sis muaj tseeb dhau los ntawm xyoo 1970 nrog cov kis las kis las thoob plaws hauv Tebchaws Meskas thiab Canada. Cincinnati's Riverfront Stadium, Philadelphia's Veterans Stadium, thiab Pittsburgh's Three Rivers Stadium ua raws li cov khoom siv turf.
Raws li xyoo 1970s tuaj rau hauv tag nrho viav vias, kev lag luam turf ua raws li cov ntaub pua plag shag thiab qhia "shag turf." Cov yarns ntev tau tsim los ntawm cov khoom siv polypropylene softer, ntau tus neeg siv-phooj ywg ntau dua li nws thawj tiam neeg ua ntej. Cov kev ua si xws li teb hockey tau txais txiaj ntsig los ntawm qhov chaw no. Txawm li cas los xij, ncaws pob tau tso rau hauv cov plua plav vim yog lub pob ncaws pob cov tshuaj tiv thaiv rau cov nyom saum npoo.
Ceev nrooj mus rau nruab nrab ntawm xyoo 1990 mus rau tiam thib peb-tiam turf, uas muaj ntau yam softer polyethylene hniav fiber ntau. Koj yuav pom qhov turf no ntawm txhua qhov chaw nyob, kev lag luam lossis kev ua si toj roob hauv pes niaj hnub no. Cov nyom hluavtaws thib peb kuj tseem muaj cov fibers ntev ntev sib nrug deb thiab "thatch," los yog cov nyom nyom tuag, nyob nruab nrab ntawm cov nyom thiab cov nraub qaum. Rau zoo tagnrho turf daim ntawv, muaj nuj nqi thiab stability, infill yog kis thoob plaws rau kev nplij siab ntxiv thaum muab txaus ko taw traction.
