本研究以水庫淤泥摻配無機性紡織污泥（乾燥取代重量百分比為10%～40%）製作雛粒，由兩種高溫設備進行1,200°C、1,250°C的輕質粒料燒製作業。連續式燒製得顆粒密度為1.00～2.00g/cm^3，吸水率介於7.2%～27.0%；兩段式燒製得顆粒密度介於0.40～1.20g/cm^3，吸水率為2.5%～19.6%，試驗結果顯示紡織污泥取代重量百分比以不大於30%為佳，可燒得符合輕質粒料規範要求之產品。紡織污泥輕質粒料雛粒經高溫燒製，燒失量約提高至5.5%～27.0%，此結果意味著添加之紡織污泥約達80%可燒失而提供相當之熱質，可以減少生產輕質粒料之能源消耗。本研究證明可以使用未經處理之原型紡織污泥做為原料產製高價值之營建材料（輕質粒料）。

The textile sludge with a replacement of dry weight percentage as 10% ~ 40% is mixed with the reservoir clay to make textile sludge lightweight pellets. With two firing types and the sintering temperature is carried out in 1,200°C and 1,250°C to produce the textile sludge lightweight aggregate. According to the test results, continuous firing can achieve a particle density of 1.00 ~ 2.00 g/cm^3 , and the water absorption rate is 7.2% ~ 27.0%. Two-stage firing can reach a particle density of 0.40 ~ 1.20 g/cm^3 , the water absorption rate is 2.5% ~ 19.6%. When the replacement of textile sludge is not more than 30%, the basic properties of the textile sludge lightweight aggregate match with the requirements. In addition, the loss on ignition is increased to about 5.5% ~ 27.0%. This result means that about 80% of the textile sludge can be burned and provide considerable amount of heat to energy consumption for producing lightweight aggregates. Finally, the experimental results of this study show that the original textile sludge can directly produce textile sludge lightweight aggregates.
