【摘要】 为对比鲜茧生丝和干茧生丝表面形貌、真丝纱疵、力学及抱合等性能的差异,将原料来源相同的鲜茧生丝和干茧生丝分别在相同的实验条件下进行烘干、微脱胶等处理。实验结果表明:处理前,鲜茧生丝与干茧生丝的微观形貌有一定差异;相同条件下,鲜茧生丝与干茧生丝的脱胶率相近;处理前后,干茧生丝的电容糙疵变化程度大于鲜茧生丝,干茧生丝的电容大糙明显增加,而鲜茧生丝的电容大糙却明显减少;两种生丝的光电糙疵变化和条干均匀性变化差异性较小;鲜茧生丝的强伸力和抱合性能较干茧生丝下降更明显,且鲜茧生丝出现了强力脆弱点。更多还原

【Abstract】 In order to contrast on the surface morphology,silk yarn defects,mechanical property and adhesion property of fresh cocoon raw silk and dried cocoon raw silk,drying and microdegumming were conducted for fresh cocoon raw silk and dried cocoon raw silk with the same source of raw material under the same experimental conditions. The results indicate that prior to the treatment,microtopography of fresh cocoon raw silk and dried cocoon raw silk has certain differences. Under the same conditions,degumming rate of fresh cocoon raw silk and dried cocoon raw silk is close. Before and after the treatment,capacitance defect change of dried cocoon raw silk is greater than that of fresh cocoon raw silk,and capacitance of dried cocoon raw silk is large and rough and increases significantly,while capacitance of fresh cocoon raw silk is large and rough and decreases significantly. Photoelectrical roughness defect change of the two kinds of raw silk and yarn evenness change have small differences. Tensility and cohesion of fresh cocoon raw silk decline more significantly than dried cocoon raw silk. Besides,strong vulnerable point appears for fresh cocoon raw silk.更多还原
