Problems solved by technology

At present, the silk cakes produced by domestic semi-continuous spunbond filament production enterprises with oil agents have always had the following problems, such as poor shape retention of the silk cakes, easy edge collapse when winding into a tube, and high end-break rate , the quality of the finished silk is low, which is not conducive to the use of downstream customers; the dry breaking strength and elongation of the dry breaking elongation of the inner and outer layers of the silk cake have large deviations, which is not conducive to the application in high-end textiles

Abstract

The invention discloses an oiling agent for semi-continuous spinning of viscose filaments as well as a preparation method and application of the oiling agent. The oiling agent is prepared from the following components in parts by mass: 60-90 parts of a lubricant, 10-20 parts of an emulsifier, 1-5 parts of an antistatic agent, 1-10 parts of a shape retention agent, 1-5 parts of oleic acid and 5-10 parts of deionized water. The oil agent prepared by the invention can form a stable emulsion with water, so that a spinning cake can be stiff and elastic and has proper shape retention, the dry strength and dry stretching deviation of inner and outer layer fibers of the spinning cake is smaller, and the edge collapse is less when the spinning cake is wound into a barrel, thereby reducing the end breakage rate of the spinning cake and improving the quality of the fibers.

Description

technical field [0001] The invention relates to the field of chemical oil agents, in particular to an oil agent for semi-continuous spun viscose filaments. Background technique [0002] Semi-continuous spun viscose filaments use cotton pulp or wood pulp as raw materials. After a series of chemical reactions and physical processes, viscose liquid is first prepared, and then silk cakes are made from viscose liquid on a semi-continuous spinning machine. Then it is made through a series of post-processing procedures. [0003] The oil agent is used in the oiling process in the post-processing process, and it mainly plays the role of lubrication, antistatic, cluster cohesion and so on. At present, the silk cakes produced by domestic semi-continuous spunbond filament production enterprises with oil agents have always had the following problems, such as poor shape retention of the silk cakes, easy edge collapse when winding into a tube, and high end-break rate , The quality of the...
