本研究首先以雙層組織之設計程式為工具,分別輸入兩個1/2斜紋為表、裏組織,將兩者之經、緯紗交錯排列,找出適當的接結點形成雙層組織。其次對表組織之正面進行色紗配列花紋圖設計,使雙層組織正面呈現花紋圖效果,而反面裏經紗全部使用竹炭紗,裏緯紗則使用竹炭紗與普通紗做不同比例配置:全竹炭紗、1:1、2:1,製作雙層樣布,並以紅外線熱像儀及熱電耦線數位溫度計檢測樣布蓄熱保溫性能。結果顯示:各樣布之正面呈現所設計之花紋圖而灰色竹炭紗位於反面,受到良好掩護,不影響樣布正面之花紋外觀,呈現外在之美觀,符合預期的設計。配置全竹炭緯紗樣布較無竹炭之普通緯紗樣布升溫值高出約3 ~ 7℃,蓄熱值約多1 ~ 2℃,顯示竹炭紗確實具有較佳之蓄熱保溫效果。
This article using double weave design tool inputs two 1/3 twill for face and back weaves and then intersect warp and weft yarns of those two weaves to form double weave by stitching points. Secondly, the tool arranging the color yarns sequence of face weave to form color effect appearance on face side of double weave and intersecting the bamboo charcoal and ordinary yarns of back weave to form reverse side. The backed warp is using all bamboo charcoal yarn, and the backed weft is using various ratio of bamboo charcoal yarn and ordinary yarns such as all bamboo charcoal yarn, 2:1, 1:1, all ordinary yarns. The double fabric samples are made to test their heat preservation by Infrared Camera Analysis System and Thermocouple Digital Thermometer. The results show the double fabrics conforming to the expecting design that possessing color effect appearance on their face sides and heat preservation of bamboo charcoal on reverse sides. The fabric using all bamboo charcoal yarn has better heat preservation than that using ordinary yarn: the higher elevation of temperature about 3~7℃ and accumulation of heat about 1~2 ℃
