Abstract

The invention relates to an antistatic polyurethane production technology which is characterized in that spinning dope for producing urethane elastic fire is added with antistatic agent; the addition amount of the antistatic agent is 1 to 5 percent of the solid content in the spinning dope; and the antistatic agent is anionic antistatic agent, cationic antistatic agent, ampholytic type antistatic agent or non-ionic antistatic agent. The antistatic performance of the antistatic polyurethane filament prepared by the technology has significant advantages to the conventional polyurethane filament under the condition of using same spinning finish; under the conditions with the temperature of 25 DEG C and the relative humidity of 65 percent, the half life of the antistatic polyurethane filament is near 0s, the static voltage is less than 1kV, and the specific resistance is less than 108 omega*cm; and the invention is suitable for back-end purposes such as high-speed tricot warping, cotton bale, and the like.

Description

technical field [0001] The invention relates to a spandex production process, in particular to an antistatic spandex production process. Background technique [0002] Due to the poor antistatic effect of spandex fibers, in order to prevent the fibers from attracting each other due to static electricity in the subsequent use process, as well as attracting short fibers to fly and causing problems such as broken filaments and uneven tension, the traditional production process needs to be added to the spinning oil. A certain proportion of antistatic agent. However, the antistatic agent will cause the instability of the spinning oil, and a higher oiling rate is required to ensure the antistatic effect, and an excessively high oiling rate makes it easy to "rewind" during the unwinding process of spandex yarn The phenomenon of broken wires. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an antistatic spandex producti...
