摘要
The study and the practical utilization of the infrared inthe textile field is analysed simply.The test method ofthe infrared transmittance(α_T)and the reflectance(α_R)in the fabric is introduced.The test results of aset of polyester/cotton plain fabrlcs show that the infra-red reflecting regulation can be expressed by quasi-co-sine function.The parameters affecting the α_T and α_Rare analysed, α_T decreases according to negative expo-nent function as the weight per square meter of the fab-ric increases,and α_R increases.Both α_T and α_R will in-crease when the mode of wavelength(λ_m) of the infra-red decreases.It can be deduced that the infrared ab-sorptance of the fabric will increase as λ_m increases inthe studied range.
The study and the practical utilization of the infrared in the textile field is analysed simply. The test method of the infrared transmittance (αT) and the reflectance (αR) in the fabric is Introduced. The test results of a set of polyester/cotton plain fabrics show that the infrared reflecting regulation can be expressed by quasi - cosine function. The parameters affecting the αT and αR are analysed, aT decreases according to negative exponent function as the weight per square meter of the fabric Increases, and αR Increases. Both αT and αR will Increase when the mode of wavelength (λm) of the infrared decreases. It can be deduced that the infrared ab-sorptance of the fabric will increase as λm increases in the studied range.
