Problems solved by technology

[0006] One of the technical problems to be solved by the present invention is that the hydrophilicity of the existing polyester staple fiber oil is insufficient, and the fiber is higher than the electric group, which may easily cause problems such as difficulty in forming a non-woven fabric and spunlace. Spinning oil agent in the fiber production process, so that the short fibers produced have good hydrophilicity and antistatic properties

Embodiment 1

[0073] 1. Oil formulation and formulation of oil emulsion

[0074] The components in the following oil formulation are mixed uniformly, and then the obtained mixture is prepared into an oil emulsion with an effective substance concentration of 3wt% with deionized water:

[0075]

[0076]

[0077] For ease of comparison, the compositions of the oil formulations are listed in Table 1.

[0078] 2. Preparation of oily fiber samples

[0079] At room temperature, 25 grams of oil-free silk was immersed in 500 grams of the oil emulsion prepared in step 1 for 10 minutes, then centrifuged in a centrifuge for 5 minutes, and the silk was taken out and dried in an oven at 110 °C for 2 hours. , Cooling in a 65RH% environment to obtain the required oily fiber sample, the oily fiber sample with an oiling rate of 0.18 to 0.20 is determined for the determination of hydrophilicity and volume specific resistance. The measurement and calculation of the oiling rate are as follows:

[0080] ...

Embodiment 2

[0103] Except adopting the following oil formulation, other operation steps are identical with embodiment 1:

[0104]

[0105] For the convenience of comparison, the composition of the oil formulation is listed in Table 1, and the test results are shown in Table 2.

Embodiment 3

[0107] Except adopting the following oil formulation, other operation steps are identical with embodiment 1:

[0108]

[0109] For the convenience of comparison, the composition of the oil formulation is listed in Table 1, and the test results are shown in Table 2.

Abstract

The invention relates to a polyester staple fiber oil, and mainly solves the problems of insufficient hydrophilicity of the existing polyester staple fiber oil, high fiber specificity, and difficulty in forming a non-woven fabric and spunlace. Short fiber oil, in parts by weight, comprising the following components: 20-40 parts of secondary alkyl phosphate salt, 20-40 parts of fatty alcohol phosphate polyoxyethylene ether, 10-30 parts of fatty acid polyoxyethylene ester, fat The technical solution of 10-30 parts of amine polyoxyethylene polyoxypropylene ether solves the technical problem well, and can be used for spinning and drawing of polyester staple fibers and processing and production of non-woven fabrics.

Description

technical field [0001] The invention relates to a polyester staple fiber oil. The oil is suitable for production processes such as spinning and drawing of polyester staple fibers and non-woven fabric processing, and belongs to the technical field of chemical fiber spinning oil. Background technique [0002] With the development of polyester staple fiber spinning technology, the total denier of the tow continues to increase, and the spinning drafting speed is greatly increased. It is 3.5 to 7 million dtex, and each silk bucket can hold 6 to 12 tons of silk. The variety of polyester staple fiber products is gradually transitioned from 1.67dtex→1.56dtex→1.33dtex→1.11dtex→0.89dtex, and 16 to 24 rollers are used for tension heat setting. 20 seconds. This puts forward higher requirements for the antistatic and friction properties of the oil. [0003] Oil film strength is a crucial indicator of the applicability of oil. When the strength of the oil film is low, the oil film is...
