上浆要素内在关系及其对高压上浆工艺的影响

Correlation of sizing factors and their influence on high pressure sizing

从上浆工艺的基本原理出发,通过推导,以公式的形式揭示经纱上浆后上浆率、压出加重率、浆液含固率、压出浆纱回潮率、压出经纱吸水率、经纱回潮率等要素之间的内在联系,据此对高压上浆的影响因素和实现途径进行分析。利用这些公式间接测定主要压浆工艺参数,以期通过实验做到准确、快速调整工艺,指导生产的目的。同时验证了德国学者托特(J Trauter)所提出的关于经纱吸水率与浆液含固率、上浆率之间关系式的合理性,并对之进行了相关修正。

Based on the basic principle of sizing and through deduction, this paper has revealed, by a series of formulas, the internal correlation of key sizing factors such as sizing regain, weight added ratio after squeezing, moisture regain after squeezing, solid content, absorption ratio of warp after squeezing, moisture regain of raw warp. And their impact on high pressure sizing is studied. In addition, by means of these formulas, experiments of ＂the process parameters in sizing＂ by indirect test methods are implemented, which focus on guiding sizing production accurately and rapidly, as well as adjustment of technique. Moreover, this paper has testified reasonable section of the experienced formula set up by Mr J Trauter from Germany, focusing on relation among the key sizing factors such as absorption ratio of warp after squeezing, solid content, sizing regain, and some revision is made to it.
