Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary agents in synthetic fiber processing technology, and particularly relates to a method for preparing a water-soluble environmentally friendly DTY oil agent. Background Art

[0002] DTY oil, also known as finished product oil or coning oil, is used in the DTY process of polyester high-speed spinning (POY-DTY) and is used in the yarn finishing process. During the stretching and twisting process, some of the pre-spinning oil is lost, necessitating a post-processing re-apply of oil, often referred to as DTY oil, to ensure smooth unwinding of the yarn from the bobbin and meet the yarn performance requirements of the weaving process.

[0003] DTY oil needs to be suitable for high-speed processing and provide good smoothness, antistatic properties and washability. At the same time, the oil washed out should not contain non-biodegradable harmful substances to ensure the environmental protection of the production process.

[0004] my country's chemical fiber industry has grown rapidly in recent years, particularly with the expansion of the polyester industry. This has led to an increasing demand for DTY finishes, both in terms of variety and quantity. However, current DTY finishes on the market present several challenges. First, they are environmentally unfriendly and may contribute to new pollution. Second, their unstable antistatic properties can lead to fiber entanglement and breakage when used in dry seasons.

[0005] Therefore, it is necessary to find a preparation method of a water-soluble environmentally friendly DTY oil with a new formula, and a preparation method thereof, wherein the prepared DTY oil is green and environmentally friendly and has excellent antistatic and smoothness. Summary of the Invention
