Description
Technical Field
The invention relates to the technical field of continuous open-width cold batch dyeing/bleaching equipment, in particular to the aspects of structural improvement of a slot dyeing operation mode and a clamp dyeing operation mode.
Background
In continuous open width cold pad-batch dyeing/bleaching equipment, fabrics are typically subjected to wet loading by either a slot dye operation or a pad dye operation, followed by a leveling nip. In the case of open width cold pad-batch dyeing/bleaching equipment, in addition to the importance of the linear pressure and the average degree of the uniform rolling liquor, the liquor carrying effect before the uniform rolling liquor is very important, under the uniform rolling of the same linear pressure, various problems are caused by insufficient liquor carrying of the fabric, such as that the left, middle and right liquor carrying quantity of the fabric is insufficient during dyeing, the deviation of the liquor rolled by the uniform rolling liquor is easily caused to cause left, middle and right color difference or color pattern, such as that the liquor carrying quantity of the fabric is insufficient during cold pad-batch bleaching, the deviation of the liquor rolled by the uniform rolling liquor is easily caused to cause left, middle and right wool effect to be inconsistent, such as that the liquor carrying quantity of the front and rear sections of the fabric is unstable, the head and tail color difference of a fabric is easily caused to cause the deviation of the liquor rolled by the uniform rolling liquor during dyeing, and such as that the head and tail wool effect of the fabric is inconsistent. Therefore, the quality of fabric on open width cold pad-batch dyeing/bleaching depends strongly on the liquid-carrying effect before the homogeneous roller mangling.
In general, when the combed fabric is in open-width cold-batch dyeing/bleaching, because the combed fabric is compact in structure, a dip dyeing operation mode is adopted, so that the combed fabric has a long time to absorb working liquid in a dip tank when passing through one or more guide rollers in the dip tank, passes through a uniform roller from bottom to top for padding, and then is taken out for rolling. However, this has the disadvantage that the more guide rolls pass, the greater the running tension. Meanwhile, the capacity of the working solution in the immersion tank is directly influenced by the number of the guide rollers, and when the capacity of the working solution in the immersion tank is too high, the circulation time of the working solution is directly prolonged, the stability of the working solution is influenced, and head-tail color difference is easily caused.
The dip dyeing operation mode has the defect of large tension, so that in the ordinary condition, when the knitted fabric is subjected to open-width cold pad dyeing/bleaching, the structure of the knitted fabric is easy to change due to the tension and the quality is influenced, so that the dip dyeing operation mode is mostly used. However, the method has the disadvantages that the time for contacting the fabric with the working solution is very short, and for the existing high-count knitted fabric, the fabric does not have enough time for carrying out sufficient liquid, and then the fabric is subjected to liquid squeezing through a uniform roller, so that the problems of color difference and color shading are easily caused.
It is assumed that the same type of fluid-carrying operation is possible in open-width cold-pad dyeing/bleaching of the needle-combed fabric, and that the best solution is achieved under the three conditions, namely 1) under controllable tension, 2) under sufficient fluid-carrying effect, 3) under low working fluid capacity.
