Uphuhliso kunye nophando lwelaphu elixhathisa i-UV; Ngenxa yophuhliso oluphezulu lwenzululwazi nobuchwepheshe, ngokungenakuphepheka kwazisa ukungalingani kwendalo, ukutshatyalaliswa kwezityalo zamahlathi, ukusetyenziswa kwe-fluorocarbon solvent kunye ne-freon ngobuninzi kwihlabathi jikelele, okukhokelela ekwandeni kwe-carbon dioxide. Ukutshatyalaliswa kwe-ozone kwi-atmospheric, ukwanda kokuvezwa kwimitha ye-ultraviolet kunye nokwanda kweemeko zomhlaza wolusu. Ngama-70s, i-tan yayiyimpawu yokufaneleka, kodwa namhlanje abantu baya kuqaphela ngakumbi ukuba ilanga liyintshaba yokunakekelwa kwesikhumba.Umvelisi welaphu le-Ripstop
Kwintsimi yezithambiso kunye nezinye iimveliso zokukhusela i-UV,Umvelisi welaphu le-Ripstopamalaphu ngoku acutshungulwa ikakhulu kwimveliso yemveliso yokhuselo lwe-UV, kwiminyaka yakutshanje, esungulwe kumazwe angaphandle ukubhloka i-UV ye-synthetic fiber ibe yinkwenkwezi entsha kushishino lwelaphu. Iintsinga ezintsha zidlula kuphela kwi-1/15 yokukhanya kwe-UV yamalaphu e-cotton kunye ne-1/6 yokukhanya kwe-UV yamalaphu okwenziwa.
Bakwabonelela ngokugquma ubushushu kunye nokupholisa. Ngenxa yokuba ifayibha yelaphu yongezwa ukubhloka izinto ze-UV,Umvelisi welaphu le-Ripstopngoko ayiyi kuhlanjwa kwaye ilahlekelwe ngumsebenzi we-sunscreen. Ngokutsho kwe-Australian Skin and Cancer Foundation, i-sweatshirt eyenziwe ngeepesenti ezingama-60 zeerayon kunye ne-40 yeepesenti yomqhaphu iyalingana ne-SPF egqibeleleyo, ngelixa i-UV isuti ye-UV eyenziwe nge-81 yeepesenti kunye ne-19 yepesenti ye-rayon. Ifayibha zokwenziwa ezintsha zinokulingana ne-SPF 36. Kwiminyaka yakutshanje, imarike yelaphu yamazwe ngamazwe ikwaphehlelele imveliso kunye nokusetyenzwa kobungqina be-ultraviolet. ikhadi ngomsonto kunye post-unyango kunye nendlela yokwaleka, oko kukuthi, inxalenye ilaphu kufuneka ukufunxa ukukhanya ultraviolet usebenzisa i-polymer emulsion okanye i-ultraviolet efunxayo kunye nomxube owomileyo we-acrylic, kwaye iqulethe i-oxide chin, i-zinc oxide, i-iron oxide kunye namanye amacandelo e-ceramic ukuqhubekeka. Okwangoku, kukho uphando oluninzi malunga nokuphuhliswa kweemveliso ze-infrared kwilizwe lethu, kodwa uphando kwiimveliso ze-ultraviolet alunanto. Ngoko ke, ukuphuhliswa kweemveliso ze-anti-ultraviolet zendwangu zineenzuzo ezithile zezoqoqosho kunye nokubaluleka okusebenzayo.
