Embodiment 1

[0040]Preparation of inorganic nano-additives: Accurately weigh 10kg sodium dodecylsulfonate in 85Kg deionized water, add 5kg nano-ZnO under the action of ultrasonic waves with a frequency of 80,000 Hz, stir at high speed for 30min to disperse, and the stirring speed is 1500-2500 rev / min.

Embodiment 2

[0042] Add the accurately weighed emulsifier and antistatic agent into the reaction kettle. The emulsifier is 10kg of nonylphenol polyoxyethylene ether (OP type), 15kg of polyethylene glycol oleate, and 13kg of polyethylene glycol laurate; Antistatic agent: 10kg of nonylphenol polyoxyethylene ether phosphate potassium salt; heat to 35°C, stir for 30min; add 26kg of smoothing agent octyl stearate, 14kg of glyceryl oleate and the inorganic nano Add 5kg of additives into the reaction kettle, keep the temperature at 35°C, stir for 25min, then add additives: 4kg of oleic acid, 4kg of water-based silicone oil, stir for 20min until uniform, cool to 30°C, pass through a 200-mesh sieve, and pack.

Embodiment 3-7

[0044] Prepare the polyester FDY nano-spinning finish in the same way as in Example 2, and the specific raw material names and proportioning ratios used in Examples 3-7 are shown in Table 1.

[0045] Table 1: Raw materials and proportioning of Examples 3-10.

[0046] components

[0047] Polyoxyl Lauryl Alcohol

[0048] components

[0049] After analysis and testing, it shows that compared with the same spinning oil without adding nano-additives, the surface tension of FDY nano-spinning oil decreases, the viscosity of crude oil slightly increases, and the stability of oil and emulsion is improved, etc., these The performance shows that the performance of polyester FDY oil has been improved. The machine experiment also proves the excellent performance of FDY nano-spinning oil. The following is the comparison of its performance with similar indicators at home and abroad.

Abstract

The nanometer polyester fiber FDY spinning oil preparation consists of inorganic nanometer additive, smoothing agent, emulsifier, antistatic agent and other additive. Owing to the added nanometer material, the nanometer polyester fiber FDY spinning oil preparation has excellent smoothing performance, capability of raising the quality of spun yarn, high heat stability, no smoke, simple compounding process, certain antibiotic capacity and other advantages, and is suitable for use in the one-step FDY spinning production line.

Description

technical field [0001] The invention relates to a polyester FDY nano spinning oil agent and a preparation method thereof, belonging to the technical field of synthetic fiber processing. Background technique [0002] With the development of the synthetic fiber industry, the demand for related textile auxiliaries has also increased rapidly. Fiber oil agent is a kind of auxiliary agent used in the process of fiber production and processing. It mainly plays the role of adjusting fiber friction characteristics, preventing and eliminating static electricity accumulation, and endowing fibers with smooth and soft properties, so as to ensure that fibers can pass through spinning, Weaving and other processes. [0003] Polyester high-speed spinning and stretching deformation is a new process developed in the 1970s, which includes two processes of pre-oriented winding yarn (POY) and stretching deformation. FDY (Fully Drawn Yarn), that is, spinning and drawing one-step process route, i...
