摘要
本研究用解舒率不同的两种鲜茧为试料,探讨了-7℃,-25℃两种温度下冷藏不同时间对茧丝工艺性质的影响。结果表明,-7℃区纤度较细,净度、强度略低,抱合略高,蛹体颜色深。鲜茧短时间冷藏对生丝强度有不良影响,对其他各项茧质无明显影响。鲜茧长期冷藏,解舒、抱合、出丝率下降,净度起伏变化,强度不随时间变化,伸长率不受冷藏影响。
Cocoon qualities were studied by storing two kinds of fresh cocoon of different reelability per-centagesat temperature -7℃ and-25℃.The results showed that have was finer,neetness and ten-acity slightly lower,cohesion strength slightly higher and pupal colour was darker at -7℃ than-25℃,but the difference of reelability percentage and elongation was inappreciable at -7℃.Ashorter time cold storage of the fresh cocoon deteriorated the silk strength elongation and didn'tobviously influence reclability percentage,etc.While the cocoon kept in a relatively long timecold storage,reeliability percentage and cohesion strength decressed,neetness went up and down,tenacity and elongation changed inappreciably with prolonged cold time.
