摘要
茧层上存在着无机物质,随着在水中浸渍时间延长,水的电导率和总硬度逐渐增加。茧层丝胶溶失率因水的总碱度和总硬度的差值增大而增加,主要影响物是NaHCO_3,其含量和茧层丝胶溶失率成直线关系。保持煮茧用水适当的碱度和硬度,使茧层丝胶的溶解和凝聚得到合适的平衡,是控制制丝用水的要点。通过Na型、H型软水、原水按比例混合的配水,合理控制煮茧用水的硬、碱度,能在不影响解舒率的情况下,较大幅度地提高出丝率。
When cocoons are dipped in water for a long time, the water electro-conductivity andtotal hardness will increase due to the inorganic substance existed in cocoon layers. Thesolubility of the sericin in cocoon layers will increase as the differences of total alkalinityand hardness increase. The substance which ahas main effect is NaHCO_3, the content ofwhich is linearly proportional to the solubility of the sericin in cocoon layers. The keypoint to control the water used for silk making is to maintain the proper alkalinity andhardness of water used for cocoon cooking so as to balance dissolving coagulating of thecocoon layer sericin. Mixing Na-type soft water, H-type soft water and raw water in pro-per proportion to gain reasonable hardness and alkalinity of cocoon cooking water, the rawsilk percentage of cocoon can be largerly increased with the reelability percentage unch-anged.
