"Sunscreen fabric" yog ib hom hnub ci-shading textile uas tsim los ntawm cov txheej txheem sib npaug siab -lub zog polyester lossis fiberglass fibers nrog hloov PVC. Cov txheej txheem no tsim cov hloov kho PVC-coated filaments, uas yog tom qab ntawd woven thiab raug rau cov kev kho mob tom ntej. Daim ntawv thov ntawm kev hloov kho PVC txheej rau ib tus neeg fibers yog thawj qhov txawv ntawm cov txheej txheem tsim khoom rau cov khoom lag luam no.
Txij li xyoo 2013, cov txheej txheem tsim khoom hauv khw feem ntau tau poob rau hauv ob pawg loj: (1) PVC-coated fibers, thiab (2) fibers impregnated nrog PVC. Hauv tsev, polyester-raws li fabrics feem ntau siv cov txheej txheem txheej (xws li, PANGEAE Sunscreen Fabrics los ntawm Teb Chaws Asmeskas); thoob ntiaj teb, txawm li cas los xij, fiberglass-raws li fabrics ntau zaus siv txoj kev impregnation (xws li, CITEL Sunscreen Fabrics los ntawm Spain). Raws li kev hloov pauv hauv cov ntaub ntawv thiab lub teeb- tswj cov txheej txheem, cov ntaub no tuaj yeem muab faib ua ntau hom: qauv qauv, fiberglass qauv, dual- txheej lub teeb- kho cov qauv, thiab jacquard{15}} qauv qauv. Qee lub lag luam (xws li Zhejiang Xidamen New Materials Co., Ltd.) tau tsim muaj kev sib koom ua ke ntau lawm cov saw hlau uas suav nrog txhua theem ntawm granulation, monofilament txheej, thiab weaving rau txheej daim ntawv thov, kev kho cua sov, thiab cov khoom kawg sib dhos. Tsis tas li ntawd, kev tshaj tawm tshwj xeeb- cov txheej txheem ua tiav- xws li ua npuas ncauj - txheej nrog cov xim dawb - tau ua haujlwm los txhim kho cov khoom ua haujlwm zoo (xws li, lub teeb- thaiv thiab UV tsis kam) thiab tiv thaiv "kev tawm tsam- los ntawm" (cov ntaub ntawv rov qab).
