Description
Technical Field
The invention relates to the technical field of boiling-off and bleaching one-step one-bath production process equipment, in particular to a multi-temperature-control-area spray box and a continuous dipping and bleaching process.
Background
At present, there are two methods for desizing, scouring and bleaching the fabrics containing size: batch impregnation and continuous roll steaming. The batch impregnation method has the advantages that: the fabric is placed in a heating medium-water and is uniformly heated, a linear temperature rise curve from low temperature to high temperature (from room temperature to 100 ℃) can be realized, and besides the size and various impurities on the fabric can be effectively removed, the damage degree of the fiber can be well controlled; the disadvantages are that: the scouring and bleaching quality stability is poor, the dyeing and printing stability is influenced, the consumption of water, electricity and steam is high, the labor intensity is high and the like, so that the intermittent impregnation method is rarely adopted. The continuous rolling steaming method has the advantages of good scouring and bleaching quality stability, small water, electricity and steam consumption, low labor intensity and the like, and is a method commonly adopted in the current industry.
However, the treatment process before the continuous roll steaming method has prominent defects, and no matter whether the desizing, the scouring and the hydrogen peroxide bleaching are carried out independently, or the desizing and the scouring are carried out in one step, the scouring and the hydrogen peroxide bleaching are carried out in one step, and the desizing, the scouring and the hydrogen peroxide bleaching are carried out in one step, only the hydrogen peroxide is used, because the high-temperature steaming temperature (100 ℃) is directly adopted, the temperature rise speed difference of the fabrics in and out of the stacked fabric layer with certain density and certain thickness is large, the decomposition conditions of the hydrogen peroxide are inevitably different, the uniformity of the scouring and bleaching effect (whiteness and capillary effect) and the damage degree of the fibers are also large, even the local fibers of the fabrics are severely damaged, and the excessive fiber damage can influence the subsequent processing, such as the phenomenon of edge breakage in mercerization and the like.
The desizing, scouring and bleaching one-bath one-step rolling-steaming pretreatment process is rarely applied to actual production, and a three-step process for desizing, scouring and bleaching is adopted in most cases, wherein the process flow and the main process conditions are as follows:
padding desizing liquid → steaming (100 ℃ multiplied by 60-90 minutes) or hot piling (60-70 ℃ multiplied by more than 6 hours) → washing → padding scouring liquid → steaming (100 ℃ multiplied by 60-90 minutes) → washing → padding bleaching liquid → steaming (100 ℃ multiplied by 45-60 minutes) → washing.
In summary, when bleaching or scouring, bleaching-bath one-step treatment or desizing, scouring and bleaching-bath one-step treatment are carried out by using hydrogen peroxide, controlling the decomposition direction (various decomposition products) and the decomposition speed of the hydrogen peroxide is the key of the process technology, wherein the control of the temperature rise speed requires slow temperature rise, namely the higher the temperature rise speed is, the more oxygen generated by decomposition of the hydrogen peroxide and the more radical seriously damaging fibers are, so that the whiteness of the fabric is reduced, and more importantly, the damage degree of the fibers is increased.
