Description

Full-process open-width pad dyeing device and process for tension sensitive fabric Technical Field The invention relates to the technical field of open-width pad dyeing of tension sensitive fabrics, in particular to a full-flow open-width pad dyeing device and a full-flow open-width pad dyeing process of tension sensitive fabrics. Background The open width pad dyeing process is one of the most widely applied continuous dyeing modes in the textile dyeing and finishing field, and generally, the fabric is subjected to dip dyeing, pad dyeing and subsequent treatment procedures in sequence, so that the dye fully permeates into the fabric and a stable dyeing effect is obtained, in the existing open width pad dyeing production line, the fabric generally enters a dye pool to finish dip dyeing, and then, redundant dye is discharged between rollers in a mechanical extrusion mode, so that the liquid content of the fabric is controlled, and the dyeing uniformity is ensured; In the process, roller extrusion is a key link affecting the running stability of the fabric and the quality of a finished product, and because the fabric is usually filled with dye liquid in fiber gaps and the fabric structure after finishing dip dyeing, the dye liquid has incompressibility, when the fabric is extruded between rollers, a large amount of liquid needs to be discharged from the fabric in a very short time, and a large instantaneous liquid resistance is easily formed in the roller area, so that the fabric is subjected to abrupt mechanical load in the area; For conventional heavy fabrics or tension-resistant fabrics, the liquid resistance and the tension fluctuation generated by the liquid resistance can be tolerated by technological parameters within a certain range, however, with the wide application of functional fibers, superfine fibers, light and thin fabrics and composite structure fabrics, more and more fabrics show higher sensitivity to running tension changes, under the existing padding process conditions, tension stirring is easily generated due to overlarge instant liquid squeezing resistance when the tension-sensitive fabrics pass through a roller, so that the problems of fabric tensile deformation, tissue structure damage, unstable breadth, wrinkling, local fracture and the like are caused, and dyeing quality and finished product consistency are seriously influenced; In the prior art, in order to reduce the extrusion load at the roller, improvement modes such as reducing the roller force, reducing the linear speed, adjusting the roller coating material or adding a cloth guide roller before and after the roller are generally adopted for relieving, however, the modes mainly belong to passive adjustment of roller parameters or operation conditions, on one hand, insufficient liquid discharge, fluctuation of liquid content or uneven dyeing are easy to be caused, and on the other hand, resistance peaks generated in the moment of liquid extrusion are still difficult to be effectively restrained when the liquid content of the fabric is large, the viscosity of dye changes or working conditions fluctuate; in addition, in the existing open width pad dyeing process, the fabric always directly enters a roller area after dip dyeing is finished, and a transitional regulation and control means for the liquid state in the fabric is lacked, so that the fabric always enters a high-pressure extrusion area in a state of high liquid filling and low compressibility, the negative influence of the liquid incompressibility on the roller extrusion process is objectively amplified, meanwhile, the traditional tension control is mostly dependent on whole line tension setting or simple guide roller regulation, real-time and local tension compensation is difficult to be carried out aiming at the change of the liquid extrusion resistance of the roller, and the unstable risk of the tension sensitive fabric in the continuous operation process is further increased; Therefore, on the premise of not sacrificing dyeing uniformity and production efficiency, the stress state of the tension sensitive fabric in the whole open width pad dyeing process is effectively managed, especially, before the fabric is subjected to dip dyeing and enters a roller for extrusion, the instantaneous resistance of the liquid in the fabric to the extrusion process is reduced, and the stable control of the fabric tension is cooperatively realized, so that the tension sensitive fabric becomes a technical problem to be solved in the field.
