Problems solved by technology

Among them, most of the emulsifiers contain alkylphenol compounds (alkylphenol AP, alkylphenol polyoxyethylene ether APEO), the biodegradation rate of these compounds is extremely low, and the biodegradation metabolites are also quite toxic to aquatic organisms

Abstract

The invention discloses a polyester DTY (draw texturing yarn) oil agent and a preparation method of the polyester DTY oil agent. The polyester DTY oil agent comprises the following compounded raw materials in percentage by weight: 75-95 percent of a smoothing agent, 3-15 percent of an emulsifying agent and 2-15 percent of an additive, wherein the sum of all components is 100 percent. The preparation method of the polyester DTY oil agent comprises the following process steps: according to the weight percentage of all raw material components of the polyester DTY oil agent, extracting the accurately metered smoothing agent into a reaction kettle, performing reaction at the temperature of 30-70 DEG C, and uniformly stirring the smoothing agent; then extracting the emulsifying agent and the additive into the reaction kettle, stirring the emulsifying agent and the additive for 3-8h, and performing cooling, filtering, discharging and packaging to obtain the polyester DTY oil agent.

Description

technical field [0001] The invention relates to the field of auxiliary agent manufacturing in synthetic fiber processing technology, in particular to a polyester DTY oil agent and a manufacturing method thereof. Background technique [0002] In the polyester filament high-speed spinning (ie POY-DTY) process, two oils are required, namely spinning oil and post-processing oil. Spinning oil is to meet the smooth progress of high-speed spinning winding and drawing twisting process. However, in the drawing and twisting process, due to heat, the oil on the silk is lost, so it must be oiled after the drawing and twisting process, that is, DTY oil is used. DTY oil should not only adapt to the oiling process under high-speed processing conditions, but also endow the fibers with good smoothness, antistatic properties, cohesion, and washability during the fiber spinning and texturing process, and its washing out The DTY oil should not contain non-biodegradable harmful substances. ...
