Embodiment 1
[0060] 1. Oil formulation and preparation of oil emulsion
[0061] Each component in the following oil formula is mixed uniformly, and then the obtained mixture is formulated with deionized water to be an oil emulsion with an effective substance concentration of 0.2wt%:
[0066] For ease of comparison, the composition of the oil formulation is listed in Table 1.
[0067] 2. Preparation of oily fiber samples
[0068] At room temperature, immerse 20 grams of oil-free silk in 200 grams of the oil emulsion prepared in step 1 for 5 minutes, then centrifuge in a centrifuge for 3 minutes, take out the silk and dry it in an oven at 110 ° C for 4 hours, then dry it at 25 ° C , Cool in 65RH% environment to obtain the required oil-containing fiber sample. T...

Abstract
The invention relates to a preparation method of universal type polyester staple fiber oil. According to the technical scheme, the preparation method of the universal type polyester staple fiber oil comprises the step of mixing all components in the oil, and the oil comprises the following components: (1) an anionic surface active agent, and (2) a non-ionic surface active agent using a polyoxyethylene chain segment as a hydrophilic group, wherein the anionic surface active agent comprises at least one of phosphate ester A and phosphate ester B; phosphate ester A comprises at least one of a compound shown in the formula I and a compound shown in the formula II; phosphate ester B comprises at least one of a compound shown in the formula III and a compound shown in the formula IV; R1-R9 is alkyl, M1-M9 is H, alkali metal or ammonium, and n is equal to 1-5.
Description
technical field [0001] The invention relates to a preparation method of a general-purpose polyester staple fiber oil agent. Background technique [0002] With the development of polyester staple fiber spinning technology, the total denier of the tow is continuously increasing, and the spinning and drafting speed is greatly improved. It is 3.5-7 million dtex, and each silk barrel can hold 6-12 tons of silk. The variety of polyester staple fiber products gradually transitions from 1.67dtex→1.56dtex→1.33dtex→1.11dtex→0.89dtex. Tension heat setting uses 16-24 rollers. 20 seconds. This puts forward higher requirements on the antistatic property and friction performance of the oil agent. [0003] The oil film strength is a crucial indicator of the applicability of the oil. When the oil film strength is low, the oil film is easily damaged when the fiber is running at high speed, and the friction force increases at the same time, causing fiber damage. At present, in order to me...
