Embodiment 1
[0062] 1. Oil formulation and preparation of oil emulsion
[0063] 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%:
[0068] For ease of comparison, the composition of the oil formulation is listed in Table 1.
[0069] 2. Preparation of oily fiber samples
[0070] 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, and then dry it at 25 ° C. , Cool in 65RH% environment to obtain the required oil-containing fiber sampl...

Abstract
The invention relates to general terylene staple fiber oil, which mainly solves the problems of great pungent taste, instability of oil emulsion and the like of existing oil. The general terylene staple fiber oil comprises the following components: (1) an anionic surfactant and (2) a nonionic surfactant which uses polyoxyethylene chain segments as hydrophilic groups; the anionic surfactant comprises at least one of phosphate ester A and phosphate ester B; the phosphate ester A comprises at least one of a compound as shown in a formula I and a compound as shown in a formula II; the phosphate ester B comprises at least one of a compound as shown in a formula III and a compound as shown in a formula IV, wherein R1 to R9 are hydrocarbyl; M1 to M9 are selected from H, alkali metals or ammonium; n is equal to 1 to 5, so that the technical problem is solved, and the technical scheme can be used for industrial production of the general terylene staple fiber oil.
Description
technical field [0001] The invention relates to a general-purpose polyester staple fiber oil, which can be used in both the pre-spinning process and the post-spinning process of polyester staple fiber production. 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 fri...
