Dabayaaqadii 1920-meeyadii, intii lagu jiray niyad-jabka weyn ee Mareykanka, dowladdu waxay soo saartay sharci cajiib ah: mamnuucid. Mamnuuciddu waxay socotay muddo 14 sano ah, iyo kuwa soo saara dhalooyinka khamriga ayaa midba midka kale ku jiray dhibaato. Shirkadda Owens Illinois waxay ahayd soo saaraha dhalooyinka ugu weyn ee Maraykanka wakhtigaas. Waxa kaliya oo ay daawan kartaa foornooyinka dhalada ah oo dansan. Waqtigaan, nin sharaf leh, dilaaga ciyaaraha, ayaa ku dhacay foorno quraarad ah, wuxuuna ogaaday in qaar ka mid ah muraayadaha dareeraha ah ee daatay ay ku dhufteen qaabka fiber. Ciyaaruhu waxay u egyihiin in Newton uu madaxa kaga dhacay tufaax, iyofiber galaastan iyo markaas waxay ku jirtay masraxa taariikhda.
Sannad ka dib, dagaalkii labaad ee aduunka ayaa qarxay, agabkii caadiga ahaana wuu yaraa. Si loo daboolo baahiyaha diyaargarowga dagaalka milatari, fiber galaas ayaa noqday beddel.
Dadku waxay si tartiib tartiib ah u ogaadeen in maaddadan da'da yar ay leedahay faa'iidooyin badan - miisaanka fudud, xoogga sare, ilaalinta wanaagsan, ilaalinta kulaylka iyo kuleylka kuleylka. Sidaa darteed, taangiyada, diyaaradaha, hubka, jaakadaha xabadaha iyo wixii la mid ah waxay isticmaalaan fiber galaas ah.
Fiber galaaswaa mid aan dabiici ahayn oo cusubwax aan bir ahayn, kaas oo laga sameeyo macdanta dabiiciga ah sida kaolin, pyrophyllite, quartz ciid iyo limestone iyada oo loo marayo habab dhowr ah sida heerkulka sare ee dhalaalidda, sawirida fiilada iyo dabaysha iyadoo la raacayo qaacido gaar ah. Dhexroorkeeda monofilament wuxuu u dhexeeyaa dhowr microns iyo in ka badan 20 microns, taas oo u dhiganta 1 / 20-1 / 5 ee fiilada timaha. Xidhmo kasta oo horudhaca fiber-ku wuxuu ka kooban yahay boqollaal ama xitaa kumanaan monofilaments ah.
Warshadaha fiber galaas ee Shiinaha ayaa kor u kacay 1958. Kadib 60 sano oo horumar ah, ka hor dib-u-habaynta iyo furitaanka, waxay inta badan u adeegi jirtay difaaca qaranka iyo warshadaha milatariga, ka dibna waxay u weecday isticmaalka madaniga ah, waxayna gaadhay horumar degdeg ah.
