Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a pre-wet size tank device suitable for a pre-wet sizing machine. Background technique [0002] As an important process of preparation before weaving, warp sizing directly affects weaving quality and weaving efficiency. The pre-weaving preparations in my country's textile industry have problems such as low sizing quality and inability to meet the sizing requirements of high-quality varieties, resulting in problems such as gray cloth grades, low added value, waste of sizing materials, and serious post-processing pollution; pre-wet sizing is an international The new sizing process has attracted widespread attention at home and abroad. In the pre-wet sizing, the warp yarns are soaked in hot water first, rolled and pressed by a pair of rolls to maintain a certain water content, and then sizing. Its advantages are: save size; improve the quality of warp yarn sizing; facilit...
