项目摘要

Demand for high-quality raw silk has been increasing greatly in Japan in recent years. The material is produced in specially bred races of silkworm, by reeling off the cocoon. The raw silk production process consists of four main stages : drying and cooking the cocoon, reeling, and bandling. Drying and cooking are the most important stages in the entire process. The quality of the cocoon filament and raw silk and subsequent stages in the process are directly affected by the quality of the drying step. Moreover, a very costly machine is required for cocoon drying. In these studies, a new filature process based on ethylene oxide gas (EOG), which is used to sterilize microorganisms, was investigated as an alternative to cocoon drying. 1. Effects of EOG : (1) Pupae in the cocoons were dead within 15-20 minutes of applying EOG.(2) Functional paralysis of pupal tissue was suggested as the cause of death by EOG.(3) Fresh raw cocoon could be kept for long periods under natural ventilation. 2. Certification of raw silk treated with EOG : (1) High-quality fresh silk was obtained in slow-speed reeling at 90 C.The cocoon quality was 86% in reelability, 3.0 denier in size and 1.167m in cocoon filament length. 3. Trial production of gas-paks and containers for EOG application : (1) Gaspaks made of polyethylene film and containers constructed from aluminum alloy were manufactured, for convenience and simplicity. (2) 100g of EOG per container was sufficient for the treatment of 30kg of fresh raw cocoons, at a cost of about 28 yens per treatment.

近年来，日本对高质量生丝的需求量大大增加。这种材料是由特别培育的家蚕品种通过缫丝而产生的。生丝的生产过程包括四个主要阶段：烘茧、煮茧、缫丝和缠丝。干燥和烹饪是整个过程中最重要的阶段。干燥工序的质量直接影响到茧丝和生丝的质量以及加工过程中的后续阶段。此外，蚕茧干燥需要非常昂贵的机器。在这些研究中，一种新的缫丝工艺的基础上，环氧乙烷气体（EOG），这是用来灭菌微生物，作为一种替代蚕茧干燥进行了研究。1. EOG的效果：（1）用药15-20分钟，茧内蛹死亡; (2)眼电图提示蛹组织功能性麻痹为死亡原因。(3)鲜茧在自然通风条件下可长期保存。2.经EOG处理的生丝鉴定结果：（1）90 ℃慢速缫丝，可获得优质鲜丝，茧质舒解率86%，纤度3.0旦尼尔，茧丝长1.167米。3. EOG用气袋和容器的试制：（1）为方便和简单起见，制作了聚乙烯薄膜气袋和铝合金容器。(2)每箱100克EOG足以处理30公斤新鲜生茧，每次处理的费用约为28日元。
