Kevlar (Kevlar) ndiro zita rechigadzirwa cheDuPont, inova rudzi rwepolymer zvinhu.Zita rayo remakemikari ndi "poly (terephthalamide)", inowanzozivikanwa se "aramid fiber".
Aramid izita rakajairika reanonhuwirira polyamide.Zvichienzaniswa nezvakajairwa zvepolyamide zvinhu zvakaita senaironi 6 uye naironi 66, aramid ine zvinhu zvakanakisa senge Ultra-yakakwirira simba, yakakwirira modulus uye yakakwirira tembiricha kuramba nekuti iyo yakapfava kabhoni cheni mucheni yemamorekuru inotsiviwa neiyo rigidne mhete chimiro.Kune mhando dzakawanda dzearamid fibers, uye aramid faibha 1313 uye aramid faibha 1414 anoshandiswa zvakanyanya.Kevlar inofanana nearamid fiber 1414. Zita remakemikari yearamid fiber 1313 inonzi polyphthalamide, inova chinhu chakanakisisa chisingadziviriri moto.
Parizvino, kudiwa kwepagore kwepara-aramid fiber (aramid fiber 1414) kuChina kunodarika 5,000 matani, kunyanya kuvimba nekutenga kunze kwenyika, uye mutengo wemusika wakakwirisa, ungangoita 200,000 yuan/ton.Vagadziri vakuru ndivo DuPont muUnited States uye Teijin muJapan.
Kana iri m-aramid fiber (aramid fiber 1313), "Taimeida" inogadzirwa neYantai Taihe New Materials Co., Ltd. ine chikamu chechipiri chepamusoro-soro chemusika munyika uye ine kukwikwidza kwakasimba kwemusika.Vatengesi vepasi rose ve m-aramid fiber vanonyanya kunzi DuPont muUnited States neTeijin muJapan.Dupont ine chikamu chepamusoro chemusika uye chakapfuma chigadzirwa, uye ichiri mutungamiri weindasitiri yepasi rose.
