Description

Dry-process antistatic spandex spinning oil agent and preparation method thereof
Technical Field
The invention belongs to the field of chemical industry, and relates to a dry spinning oil agent, in particular to a dry antistatic spandex spinning oil agent and a preparation method thereof.
Background
Polyurethane elastic fiber, namely spandex in short in the conventional name, is called as 'flavor-essence-like' textile raw material essential to the modern textile clothing industry due to excellent elasticity and good comprehensive performance, and can be used for all fabrics needing good elasticity recovery rate due to excellent elongation at break and breaking strength, so that the polyurethane elastic fiber has a good development prospect with high application value. The spandex spinning process mainly includes dry spinning, melt spinning, wet spinning, reaction spinning and the like, wherein the dry spinning yield reaches 80 percent of the total spandex yield in the world, and the spandex spinning process belongs to the main spinning methods and is typically represented by Lycra fibers of the Invidata company and Dorlastan fibers of the Bayer company.
The total yield of spandex in 2019 in China is about 85 ten thousand tons, the yield of spandex in 2013 to 2019 in China is increased by 6.63 percent in a combined yield year, and the yield tends to be further increased. Along with the increasing of the yield of the spandex, the yield of spandex spinning oil agents is correspondingly increased. The spandex oil agent is applied by an oil nozzle or a roller to form a layer of protective film on the surface of spandex fiber, so that the adhesion between the fibers is prevented. The good spandex oil agent can enable the silk threads spun after the spandex silk is oiled to have good smoothness, bundling property and antistatic property, and the inner layer and the outer layer of the spandex silk threads are good in revolving and unwinding property, continuous in silk and non-slip in the processing process after the spandex silk threads are formed into cakes.
At present, the companies for producing spandex oil mainly include the U.S. Golston company, the Japan bamboo oil and fat company and the Songbo oil and fat company abroad, and the domestic companies such as Shandong Dayi, Beijing Zhonghan Haitian Ningbo Hitachi, and the like. Although there are many companies for producing spandex spinning oil at home and abroad, the variety and specification of the oil are also many, but there are some problems of irreconcilability, such as generally poor antistatic performance of the oil in the spinning process, collapse and filament breakage of spandex filaments in the using process of the subsequent process, poor unwinding performance between the internal energy and the outer layer, slow unwinding speed and the like. For example, the spandex spinning oil agent described in patent US3717575 is composed of single mineral oil, silicone oil and amino modified silicone oil, and such oil agent is characterized in that the spun spandex has good hand feeling and smoothness, but one fatal defect is poor antistatic performance in the using process. Patent CN101525788 is to mix polydimethylsiloxane and phosphate as an antistatic agent to be added into the spinning solution, so that the product has antistatic property, but the usage amount of raw materials is large, the cost is high, the process is complex, and the practical application and popularization are not facilitated. Patent CN106521965B adopts a large amount of dimethyl silicone oil as smoothing agent and graphite alkene to use, has played antistatic effect to a certain extent, but the drawback is exactly that the cost promotes by a wide margin, is unfavorable for promoting equally. Patent CN104372446A adopts quaternary ammonium salt cationic surfactant as antistatic agent added into oil agent, which has a certain antistatic property, but the defects of edge collapse, filament breakage and poor unwinding property are easy to occur in later use, and the requirement in the actual spandex spinning process can not be completely met.
