The single factor analysis of 5 PEG additional amount of embodiment
Using the method for embodiment 4, in the case where only changing PEG additional amount, to the odd-shaped cross section viscose rayon of preparation
Degree of hollowness, spinning change the influence of a rate, dry breaking strength, are shown in Table 1.
Table 1 changes PEG additional amount, changes a rate to the degree of hollowness of odd-shaped cross section viscose rayon, spinning, does breaking strength
It influences
As can be seen from the above table, when PEG relative to first fibre in spinning viscose additional amount be 2.4 wt% when, preparation it is different
Tee section viscose rayon indices are best.Therefore embodiment 9 is optimum embodiment of the present invention.
Al is not added in 12 coagulating bath of embodiment2(SO4)3Single factor analysis
Using the method for embodiment 4, Al is not being added in coagulating bath2(SO4)3In the case where to the performance indicator of fiber such as
The following table 2:
Table 2: Al is not added in coagulating bath2(SO4)3Influence to the fibre quality index of preparation
Upper table, which can be seen that, does not add Al in coagulating bath2(SO4)3In the case where, in the viscose filament with abnormal section of preparation
Reciprocal of duty cycle, which has, largely to be declined, and moisture pick-up properties and quick-drying the performance decline of fiber are obvious.
Al in 14 coagulating bath of embodiment2(SO4)3Concentration single factor analysis
Using the method for embodiment 4, only change Al in coagulating bath2(SO4)3Concentration, it is long to the odd-shaped cross section viscose glue of preparation
The influence of silk indices performance, is shown in Table 3
Table 3 changes Al in coagulating bath2(SO4)3Concentration, the influence to the viscose filament with abnormal section index performance of preparation
As can be seen from the above table, as Al in coagulating bath2(SO4)3Concentration when being 11-12 g/l, the odd-shaped cross section of preparation is viscous
The degree of hollowness of glue long filament is higher, moisture pick-up properties and quick-drying better performances.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
