Prediction of the Exposure Endpoint of Textile Color Fastness to Light

Abstract The color fastness to light of textile in the product standard is always tested by method 3 GB/T 8427, which determines endpoint exposure according discoloration blue wool sample. aging xenon lamp for resulted different sun times references required same level. As a result, difficulty testing increased, and test accuracy was also affected. In this paper, relationship between time service lamps studied through real-time monitoring accurately predict fastness. class curve fitted as: y 1 =10.4785+6.39539E −5 x +2.53603E −7 2 ; 4 underexposure =38.17692-0.00131x +2.78006E −6 -4.81015E −10 textiles wetted with artificial perspiration =13.78014-5.53089E −4 +1.53274E -2.92228E +1.02685E −14 . practical effective, has value textiles, important guiding significance daily future.
