the alkali treatment of jute yarn enhances yarn「s elongation percentage to 5 times and it」s elastic extension to 6.8times, decreaces it's strengtll a little.
适当的堿变性处理工艺可使洋麻纱比普通洋麻纱全伸长弹性增加6.8倍;伸长率增加5倍;
the result is that the agc system of locking mill elastic extension is better than that of locking roll-load and mill gap.
