Fuzzy Orthogonal Optimization of the Processing Parameters of Cocoon Cooking with Polyoxyethylene Castor Oil

以聚氧乙烯蓖麻油的滴加速度、低温渗透段温度、中水段温度、煮茧巡回时间为评价因子,实缫解舒率、万米吊糙、洁净分数为评价指标,采用模糊正交法对聚氧乙烯蓖麻油助剂辅助煮茧的工艺参数进行综合评价,得到最佳的工艺条件为聚氧乙烯蓖麻油的滴加速度2 mL/min,低温渗透段温度70℃,中水段温度80℃,煮茧巡回时间10 min。在此工艺条件下的实缫对比试验结果表明,聚氧乙烯蓖麻油能够改善煮茧效果,提高缫丝成绩。表明用模糊正交方法对其使用工艺参数进行优化是可行的。

Fuzzy orthogonal method was used to comprehensively evaluate the technological parameters of cocoon cooking with polyoxyethylene castor oil auxiliary.The polyoxyethylene castor oil dropping speed,permeability section temperature in low temperature,water temperature,cooking time were used as evaluation factors and reelability percentage,frequency of rushing upon cocoons per 10 000 m,neatness fraction were used as evaluation parameters.The results showed that the optimal technological conditions were the dropping speed 2 mL/min,the low temperature segment 70 ℃,the water temperature 80 ℃,cooking for 10 min.Under the optimal conditions polyoxyethylene castor oil could improve the cooking effect and increase silk reeling scores.The optimization of cocoon cooking parameters by orthogonal design is practical.
