Problems solved by technology

In fact, the influence of temperature on the refractive index of different substances is different, and the existing temperature deviation coefficient or temperature deviation table for temperature correction is not suitable for most other substances
Therefore, there is a deviation in the determination of the concentration of the oil mother liquor with a refractometer

Abstract

The invention relates to the technical field of spinning, and discloses a device and method for controlling oil-containing uniformity and stability of tows during acrylic fiber oiling. The device comprises a concentrated oil agent supplementing line, an oil agent circulating line, an oil agent mother liquor conveying line, a tempering oiling tank, a thin oil agent recycling line and a tempering tank which are sequentially connected in the flowing direction; the oil agent circulating line is connected with an outlet of the tempering tank, and the oil agent mother liquor conveying line is provided with an oil agent mother liquor backflow line flowing to the tempering tank; and the oil agent mother liquor conveying line is sequentially provided with an oil agent filter, an oil agent heater, aCoriolis mass flow controller and a differential pressure type mass flow controller in the flowing direction. According to the device and method, the Coriolis mass flow controller and the differential pressure type mass flow controller are connected to the oil agent mother liquor conveying line in series in the front-back direction, the flow of oil agent mother liquor can be accurately and stablycontrolled and the composition of an oil agent mother line can be adjusted through the combined control of the two mass flow controllers, and therefore acrylic fibers can be oiled uniformly and stably.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a device and a method for controlling the uniform oil-containing stability of acrylic fiber when oiling. Background technique [0002] As we all know, in the chemical fiber spinning process, oiling the fibers is an essential step. The reason is that the spinnability of chemical fibers is poor, and the spinning oil is coated on the surface of the fibers when oiling, which can make the fibers have good lubricating properties, excellent antistatic properties and a certain oil film strength, so that there is no fuzz in the fiber production process. , Broken head, reduce white powder, precipitates, etc. In addition, the spinning oil also has a great influence on the post-spinning processing of fibers (including spinning, and then to the processing of the final fabric). High-quality spinning oils should ensure that the post-processing process can also proceed smoothly. In the spinni...
