Spandex silicone oil-free agent

Abstract

The invention discloses a spandex silicone oil-free agent which is prepared by mixing the following components in percent by mass: 20-90% of mineral oil, 1-40% of an emulsifier, 1-20% of an antistaticagent and 1-45% of a lubricant at a certain temperature, for a certain time and at a certain stirring speed. An oil agent contained in a fabric containing spandex before dyeing is more easily cleanedthoroughly, so that the fabric is more uniformly dyed, and the cleaned silicone oil-free agent is more easily degraded, and therefore, permanent pollution to the environment is avoided.

Description

technical field [0001] The invention relates to a spandex spinning oil, in particular to a non-silicon oil for spandex spinning. Background technique [0002] Polyurethane elastic fibers usually refer to fibers containing at least 85% polyurethane segments in synthetic fibers. In the United States, the commercial name of polyurethane elastic fibers is commonly known as spandex, in the UK it is Elastane, in Japan it is ESPA . However, most countries in the world have followed the name of the United States and called this type of fiber Spandex. At present, according to the naming habit of traditional fibers in my country, this type of elastic fiber is called spandex. The real large-scale commercial production of spandex was realized in 1958 by Du Pont Company of the United States. into large-scale commercial production. Due to its excellent mechanical properties and characteristics, countries all over the world have successively invested in production. The production of sp...

[0005] Secondly, when the existing spandex waste silk is spun back, because there is a silicon-containing oil agent on the surface of the waste silk, the silicon raw material contained in the spinning stock solution prepared after dissolving the spandex waste silk is easily oxidized into silicon dioxide at high temperature in the tunnel. During the recovery process, the hot air adheres to the return air filter of the upper tunnel and causes blockage (Jiangsu Qiaoxin Fiber Co., Ltd. and Jiangsu Zecheng Fiber Co., Ltd. currently have this problem), which eventually leads to abnormal production, and the filter needs to be cleaned regularly to maintain stable production
