書櫃用材對紙張表面顏色之影響

Effect of Wood Used for Book-cabinet on the Surface Color of Papers

摘要


本試驗之主要目的係研究書櫃與書架用材對紙張表面顏色之影響,所測試的六種試材包括肖楠、扁柏、紅檜天然木、紅檜造林木、鐵杉與粒片板六種,紙張表面顏色之變化則以明度留存率、色差值與黃化指數加以比較,由試驗結果得知肖楠、扁柏與紅檜天然木會使紙張黃化,影響之程度以肖楠最為明顯,其次為扁柏,再其次為紅檜天然木,而紅檜造林木、鐵杉與粒片板三種用材對紙張顏色的影響甚為輕微。

The main objective of this study is to examine the effect of wood used for book-cabinet on the surface color of papers. Several different woody materials including Taiwan incense-cedar, Taiwan yellow cypress, Taiwan red cypress, Taiwan hemlock and particleboard have been investigated. The changes in surface color of papers stored with different woody materials are compared based upon the variations of brightness retention, color difference and yellowness index. The results obtained demonstrate that Taiwan incense-cedar, Taiwan yellow cypress and Taiwan red cypress cause the yellowing on paper surface. The yellowing tendency induced by woods in decreasing order is: Taiwan incense-cedar>Taiwan yellow cypress>Taiwan red cypress.
