粗真空前处理低温煮茧法

Rough Vaccum Pretreatment and Low-Temperature Cocoon Cooking

针对原料薄头茧多、茧层结构疏松、毛脚率高的特点，通过常规温差渗透煮茧和粗真空低温渗透煮茧工艺对照试验比较和生产实践，表明后者在降低缫折、提高出丝率方面效果显著，是对该特殊性质原料茧行之有效的工艺新技术。

Regular temperature-difference permeation cocoon cooking and rough vaccum low-temperature permeation cocoon cooking respectively applied to excessive then-end and early-gathered cocoons with loose shelled structure in comparative experiment and large-scale reduction show the latter achieves much better results in reducing renditta and enhancing silk yielding, becoming new technology well applicable to the above-mentioned specific cocoons.
