预湿上浆工艺与机理研究

经纱上浆大都采用传统的方法，即经纱从经轴上退绕下来直接进入浆槽进行上浆，而对采用预湿上浆的研究并不多见。文章通过预湿上浆工艺的实验，研究了其最佳工艺参数，并探讨了预湿上浆的作用机理，结果表明：预湿上浆是一种先进且适用的新型浆纱技术。

Pre-wet Sizing: Process and Mechanism

In mostcases, conventional process is adopted for warp sizing, i.e. the warp is unwound from the beam and directly sentinto thesizing box, and while pre-wetsizing method is seldom used. This paper studies the processing parameters of pre-wet sizing process through experiments and analyzes the mechanism of pre-wet sizing technique. The resultshows that pre-wet sizing is an advanced and applicablesizing technology.
