Problems solved by technology

[0003] Many existing spinning oils are mainly composed of polyether compounds. During the polyester POY–DTY process from drawing and oiling to twisting and winding, with continuous heating and water evaporation, the concentration of oil on the surface of the fiber increases from About 10% keeps increasing until it is close to anhydrous state. During this period, some polyether compounds in the oil agent, especially those monomer components with high polyoxyisopropylene content in the random polyether chain segment, at a certain concentration Phase separation is easy to occur in the temperature range, forming a shear-thickened anti-thixotropic fluid emulsion, which affects the spinning quality

Abstract

The invention discloses spinning oil for POY (polyester pre-oriented yarn) and a preparation method of the spinning oil. The spinning oil is prepared from, by weight, 10-15% of an emulsifier, 15-22% of a smoothing agent, 5-10% of an antistatic agent, 40-50% of deionized water and the balance additives, wherein the smoothing agent is a mixture of a polyether compound with one of mineral oil or C16-C18 alcohols, the polyether compound refers to C8-C12 fatty alcohol oxygen ethyleneoxy isotrimethylene random polyether or C12-C18 fatty acid amide polyethoxylated ester, and a preparation temperature is 30-40 DEG C. The spinning oil is stable, safe and harmless, and a preparation process saves energy and is low in cost.

Description

technical field [0001] The invention relates to an auxiliary agent for polyester spinning, in particular to a spinning oil for polyester filament POY and a preparation method thereof. Background technique [0002] The oil agent is a chemical additive sprayed on the surface of the fiber during the spinning, drawing and post-treatment of the chemical fiber to improve the smoothness, bundling and antistatic properties of the fiber, and improve the drawing, crimping and winding of the fiber. And textile processing performance, to avoid wool and broken ends in the production process, to ensure the smooth progress of the production process. Oil agent is an essential processing aid in spinning process such as polyester. [0003] Many existing spinning oils are mainly composed of polyether compounds. During the polyester POY–DTY process from drawing and oiling to twisting and winding, with continuous heating and water evaporation, the concentration of oil on the surface of the fibe...
