摘要
对印度多化、二化松驰结构的蚕茧进行了压力煮茧的研究。实验按照正交排列布局L 2 7方法设计。研究了浸渍温度和时间 ,蒸汽渗透时间 ,水渗透时间和煮茧时间对丝质性状的影响。发现浸渍温度与废物率和洁净之间有密切关系 ,而浸渍时间与清洁百分率和拉伸率有显著相关 ;蒸汽渗透时间与解舒丝长、生丝率、清洁和生丝的抱合有显著相关 ,对生丝强力有显著影响 ;煮茧时间对生丝的清洁性状有重要影响。研究表明 ,经热空气干燥的多化、二化蚕茧能有效地用高压 (压力 )煮茧 。
The suitability of pressurised cooking for loose shell structured Indian multi×bivoltine cocoons was studied. The experiment was designed using orthogonal array layout L27 method.The effect of retting temperature and duration, steam permeation duration, water permeation temperature and cooking duration were studied with respect to various reeling and quality parameters. The retting temperature was found to have significant relation with waste percentage and neatness defects whereas retting duration has significant correlation with cleanness percentage and elongation percentage. The steam permeation duration was found to have significant relation with non-breakable filament length, raw silk percentage, cleanness defects and cohesion of raw silk and water permeation temperature was found to have significant effect on raw silk percentage and tenacity of raw silk. The cooking duration has significant influence on cleanness characteristics of raw silk. The study revealed that hot air dried multi×bivoltine cocoons can also be effectively cooked on pressurised cooking and the suitable cooking conditions were also derived from this study.
