For improving the polymeric unwinding easy zbility of polymerization workshop section, be employed in a certain amount of agent dolomol that relaxes of separating of adding in the condensate usually, find through experiment; Influence main two additions that factor is a dolomol of polymeric unwinding easy zbility, and the particle diameter of dolomol, confirm that finally at the dolomol addition be 0.1-1.5% (mass content); When particle diameter is 0.3-5 μ m; Has unwinding easy zbility preferably, when selecting particle diameter to be the dolomol of 0.3-2 μ m, because particle diameter is littler, it is narrower to distribute; Controlling the dolomol addition simultaneously is 0.5-1%, has optimum efficiency.
(2), spinning: in the operation that oils, finish is selected organic silicone oil, in organic silicone oil, is added with dolomol, and the quality percentage composition of dolomol is 0.5-1.5%, the rate that oils 4-6%; In the coiling operation, preliminary draft is 0.8-1.1, connects to press to be 10-15Kg.
The selection of spinning oil: for guaranteeing the unwinding easy zbility of spandex silk; Need carry out oiling treatment to the spandex silk in spinning workshop section, the addition of the selecting for use of finish kind, dolomol and the finish rate that oils directly have influence on the unwinding easy zbility during the road uses behind the spandex silk.Find through experiment: finish selects to contain the organic silicone oil of dolomol, and the addition of dolomol is 0.5-1.5% (mass content), and control oils rate when 4-6%, can effectively improve the unwinding easy zbility of spandex silk; Especially the addition of controlling dolomol is 0.5-1% (mass content), and when selecting the transparent liquid dolomol, best results; This is that easy zbility is better because the dispersiveness of transparent liquid dolomol is better.
Preliminary draft: for improving the unwinding property of fine denier spandex silk, the selection of spinning process condition is extremely important, and the preliminary draft of spinning connects the setting of pressure with reeling; With the unwinding property that directly has influence on spandex; Confirm that through experiment to the fine denier spandex silk, the preliminary draft of spinning is 0.8-1.1; Connect and press, can obtain unwinding property very to 10-15Kg.
Beneficial effect of the present invention is following:
A kind of preparation method who is applicable to the spandex fibre in high-speed unwinding field of the present invention; Be applicable to the low stress fine denier filament (below 20 dawn) in preparation high-speed unwinding field; Aspect three of unwinding easy zbility that improves polymeric unwinding easy zbility, spinning workshop section raising spinning oil in polymerization workshop section and the unwinding easy zbilities that improves spinning technique etc.; Process conditions and technological parameter are optimized, have improved the unwinding easy zbility of spandex silk effectively, through detecting; Adopt the 20D polyurethane fiber thin denier silk of the present invention's preparation, its unwinding property can reach 27%.
Below in conjunction with the specific embodiment the present invention is described further.
