Iko kuvandudza uye kutsvagisa kweUV inodzivirira jira; Nekuda kwekukura kukuru kwesainzi uye tekinoroji, zvakaunza kusaenzana kwezvakatipoteredza, kuparadzwa kwezvinomera zvesango, kushandiswa kwefluorocarbon solvent uye freon yakawanda pasi rese, zvichikonzera kuwedzera kwecarbon dioxide. Kuparara kweozone layer mumhepo, kuwedzera kuratidzwa kune ultraviolet mwaranzi uye kuwedzera zviitiko zvegomarara reganda. Mune 70s, tan yaimbova chiratidzo chehutano, asi nhasi vanhu vari kuwedzera kuziva kuti zuva ndiro muvengi wekuchengetedza ganda.Ripstop jira mugadziri
Mumunda wezvizoro uye zvimwe zvigadzirwa zvekudzivirira UV,Ripstop jira mugadzirimachira ave kunyanya kugadziriswa kugadzirwa kwemaindasitiri ezvigadzirwa zvekudzivirira UV, mumakore achangopfuura, zvakatangwa munyika dzekunze kuvhara UV synthetic fiber yave nyeredzi nyowani muindasitiri yemachira. Iwo mafiber matsva anopfuura ne1/15 chete yeUV mwenje wemachira edonje uye 1/6 yeUV mwenje wemachira ekugadzira.
Vanopawo kupisa kwekudzivirira uye kutonhora. Nekuti iyo jira fiber inowedzerwa kuvhara UV zvikamu,Ripstop jira mugadzirisaka haizoshambidzwa uye kurasikirwa nebasa rezuva. Sekureva kweAustralia Skin and Cancer Foundation, sweatshirt yakagadzirwa ne60 per cent rayon uye makumi mana muzana yedonje yaizove yakaenzana neSPF yakakwana, ukuwo sutu yedonje yeUV yakagadzirwa ne81 muzana rayon uye 19 muzana ye new synthetic fiber ingangove yakaenzana neSPF 36. Mumakore achangopfuura, musika wepasi rose wemicheka wakatangisawo kugadzira nekugadzirisa ultraviolet humbowo. Kadhi yeshinda ine post-kurapwa uye yekupotera nzira, kureva, muchikamu chejira chinoda kutora ultraviolet mwenje uchishandisa polymer emulsion kana ultraviolet absorbent uye acrylic yakaoma musanganiswa, uye ine oxide chin, zinc oxide, iron oxide uye zvimwe zveceramic zvikamu zve. processing. Parizvino, kune kumwe kutsvagisa pamusoro pekuvandudzwa kwezvigadzirwa zve infrared munyika yedu, asi tsvagiridzo yezvigadzirwa zve ultraviolet haisati yashaikwa. Naizvozvo, kuvandudzwa kwe-anti-ultraviolet machira akatevedzana zvigadzirwa zvine humwe hupfumi hunobatsira uye hunoshanda kukosha.
