This article aims to establish the region of whiteness and equation expressing the degree of whiteness on the basis of the factors relating to the whiteness of garments.
The fabrics slightly dyed near white were finished with various concentrations of fluorescent bright eners. The test samples were prepared by exposing the finished fabrics under the light of the weather-Ometer. These test samles were evaluated by the paird comparison and the semantic differential method under the predetermined viewing conditions. The equation expressing the region of whiteness are derived in such a manner that the equation conforms to the experimental data. Also, these data have been correlated with the CIE 1976 L^* u^* v^* values of colour measurement and the equation expressing the whiteness degree is obtained. The region of whiteness is expressed on the CIE chromaticity plane by the following linear equation:
y=1.448x-0.142 (0.306<x<0.324)
The degree of whiteness, which agrees well with the visual whiteness ranking, is expressed by:
W=100- { (L^*-L₀^*) ²+ (u^*-u₀^*) ₂+ (v^*-v₀^*) ₂} ^1/2
(L^*: 91.74, u^*: -2.44, v^*: -17.76)

This article aims to investigate influences of the fiber composition of face fabric and construction of base fabric on the dimensional change of textile laminates caused by fusing process and moisture absorption and desorption of fused laminates. The experiments have been carried out assuming that fusible interlinings are used in the front bodice of jackets. Fusible interlinings whose base fabric is plain-woven, knitted or non-woven fabric have been fused to the face cloth of different blending ratio of wool/polyester fibers. The results are summarized as follows:
(1) The dimensional change of fused laminates caused by a fusing process is dependent on the blending ratio of wool/polyester fibers of face fabrics.
(2) The shrinkage and its recovery of fused laminatee of higher blending ratio of wool fibers are dependent on the construction of base fabrics. The shrinkage of laminates fused fusible interlinings of plain weave base fabric is less than those of knit or non-woven base fabrics.
