【摘要】 对影响黄麻、红麻脱胶的水质、温度、ｐＨ值、无机盐、浴比和麻的特性等因素的研究结果表明，天然水源中细菌含量变化于１０￣４—１０￣６ｃｆｕ／ｍｌ之间，沤麻后增至１０￣７—１０￣８ｃｆＵ／ｍｌ；沤过麻的水只要控制其ＣＯＤ在４００ｍｇ／Ｌ以下便可加速再次沤麻；沤麻最适水温和起始ｐＨ为３８℃和５．０；添加麻重０．１％的尿素可缩短脱胶时间４０％，浴比在１：１５—１：３０时脱胶效果无差异；红麻较黄麻易脱胶，鲜皮脱胶比鲜茎快。更多还原

【Abstract】 Effect factors of jute and kenaf retting, such as water resources, microbial population,temperature, pH value, COD, mineral additon, ratio of plant material to water and characteristics of bast fibre crops,were all reported in this paper.It showes from the researches that microbial quantity in natural water is 10￣4 10￣6 cfu/ml. After Retting, it gets up to 10￣7-10￣8 cfu/ml. Retting duration of second time can be reduced by retting effluent diluted properly with fresh water if COD in retting water is not over 400 mg/L.The optimum retting temperature is 38℃ .The best effect can be obtained at primary pH 5.0 Urea added into retting water by 0.1% of green stem or ribbon weight can cut down retting time by 40%.There is no difference in retting effects when ratio of green stem or ribbon to water is 1:5-1:30. Kenaf retting is easier than jute retting, and green ribbon is easier than green stem retting.更多还原
