The pump speed of described main pump circulation is 80 ~ 95% of normal speed, and frequency is 40 ~ 47.5HZ, and best pressure reduction is between 1.3 ~ 2.5bar.
Viscose filament yarn is that under a kind of cryogenic conditions, water-swellable rate is very high, can reach a few multiple of fiber own and the high density cheese formed; And the restriction that the density of cheese is subject to the mode that turns around cannot avoid the low-density technique that rationally meets all the time; High for the density uniformity requirement of the upper and lower side of bobbin at viscose cheese especially long filament, if occur just there will be uneven dyeing look flower under there is the slightly large prerequisite of density at which position of whole bobbin.Because the pressure exchanged and number of times are the emphasis determining dyeing quality, the control criterion of pressure differential and density are one of key factors determining dyeing quality in real process; Long filament causes the change of dry fiber and wet fiber condition to be clearly the uncontrollable and satisfied key exchanged that circulates of large bath raio for the shrinkage coefficient (absorption of water of internal organizational structure is very high) of thermal expansion and cold water; It is cause the obstacle exchanging dyeing so cannot meet the coloration requirements of the standard cartridge protonatomic mass (0.8-1.0KG) of fiber that the long filament viscose fiber staining of large bath raio can not be greater than outside pressure at the pressure of the main pump that is subject to circulating under the condition contaminating outer loop pressure; Large bath raio can be subject to too much water circulation impact and causes the injured formation mechanical damage of fiber filoplume and cannot meet quality in the process accelerating circulation main pump, if take the function of this equipment to carry out producing, coloured fibre physical injury becomes defective work; Short rayon fiber large bath raio in actual production process is also can only produce under low-density condition, but long filament comparatively short fiber require with change higher, this is material own to turning around, a lot of changes occurs in the requirement of equipment, technique; Especially the instability of the chemical fiber wire moulding process of long filament is to one of all process conditions new obstruction, the less cleaning position, local of fiber can be there is in (high temperature--high-alkali--desulfurization--is rolled and washed) technique in general long filament in producing shaped technique, this quality is be a large adjustment to finished product filament dyeing technique is also the very scabrous problem of existing market technology, and dew white flowers is very easy to produce.The present invention mainly solves the relevant issues such as density, pressure reduction, pH value in bobbin dyeing technology on the basis of above-mentioned research, thus achieves ultra-low bath ratio dyeing.
