Requirements of pad dyeing machine for rolling car

Pad dyeing machine is suitable for large-scale continuous printing and dyeing process with high labor efficiency and low production cost. It is the main dyeing equipment for cotton, chemical fiber and their blended fabrics. Rolling mill is the key equipment in continuous pad dyeing machine, its performance directly affects the quality of cloth. Requirements for rolling mill:

The rolling liquid should be uniform, and the liquid carrying rate of front, back, left, middle and right should be uniform. At present, the ideal rolling mill is the uniform rolling mill, which uses compressed air at both ends of the roller and oil pump inside the roller to pressurize. By adjusting, the pressure in the whole range is the same, which is not easy to cause deep and shallow defects in the edge and middle of the fabric. A pair of rolls of uniform rolling mill are all soft rolls. Dip rolling generally has several forms, such as one dip rolling, one dip two rolling, two dipping two rolling or multiple dip one rolling, depending on the fabric, equipment, dyes, etc. If the fabric is thick, poor in permeability and high in dye content, it is suitable to use one dip and one roll. During dip rolling, the liquid carrying rate of fabric should be lower, and the rolling residual rate should be high. The more serious the migration during drying, the more likely it is to produce uneven dyeing. When the moisture content is below a certain value, the migration is not significant.

The above is about today's pad dyeing machine content, we use hard sweat and constant persistence to create today's results, to create a better future for customers, today's small editor's explanation is here, more information welcome to inquire.
