Problems solved by technology

If such a treatment agent, that is, a treatment agent in a state where the components are separated, is attached to the synthetic fiber, the treatment agent cannot be uniformly attached to the synthetic fiber, which causes frequent problems in the yarn making process and the processing process.
Similarly, if the emulsion stability of the treatment agent is poor, the treatment agent cannot be uniformly attached to the synthetic fiber, which causes frequent problems in the yarn making process or processing process.

manufacture example 1

[0126] In a 2L autoclave (autoclave) capable of stirring and temperature regulation, with an alkylene oxide stuffing box, a nitrogen supply pipe, and a pressure regulating pump, put 193 g of C as alcohol. 12～13 Alcohol, 0.9 g potassium hydroxide as base catalyst. After replacing the inside of the autoclave with nitrogen, a dehydration operation was performed at 100 to 110° C. for 1 hour while stirring. Next, in order to achieve the desired molar ratio, at a gauge pressure of 0.0-0.4MPa and a reaction temperature of 140-150°C, 132g of ethylene oxide is put in as the first stage, and a mixture of 116g of propylene oxide and 132g of ethylene oxide is put in. As the second stage, 264 g of ethylene oxide was charged as the third stage, and the addition polymerization reaction was carried out for about 8 hours. Thereafter, the obtained polyoxyalkylene alkyl ether was neutralized and recovered with 1.4 g of lactic acid. Thus, polyoxyalkylene alkyl ether (POA-1) was obtained.

manufacture example 2～12 and manufacture comparative example 1～12

[0128] POA-2-12 and POA-D1-12 were obtained like manufacture example 1 except having changed the addition mole number of alcohol, ethylene oxide, and propylene oxide of each example described in Tables 1-4. The cloud point of a 1% by weight aqueous solution of polyoxyalkylene alkyl ether and the melting point of polyoxyalkylene alkyl ether were measured as follows.

[0129]

[0130] A 1% by weight aqueous solution of polyoxyalkylene alkyl ether was prepared. Next, the cloud point test solution was temporarily clouded by heating, and the temperature at which the cloudiness disappeared was defined as the cloud point.

[0131]

[0132] Take the polyoxyalkylene alkyl ether with a capillary tube of the specified size, make it close to the mercury bulb of the thermometer, raise the temperature slowly in the air bath, the sample melts, and take the temperature when it becomes opaque as the melting point .

[0143] Except having changed the addition mole number of alcohol, ethylene oxide, and propylene oxide described in Table 5, it carried out similarly to manufacture example 1, and obtained polyoxyalkylene alkyl ether. The obtained polyoxyalkylene alkyl ether is esterified with fatty acid as follows.

[0144] Add 775g of polyoxyalkylene alkyl ether and 248g of lauric acid in the reaction container with stirring blade, heating device and dehydration pipe, and carry out esterification reaction at 180~210° C. for 8 hours. Thus, polyoxyalkylene alkyl ether ester (POAEE-13) was obtained.

Abstract

The purpose of the present invention is to provide a synthetic fiber treatment agent having exceptional product stability when the synthetic fiber treatment agent is stored at low temperature, and exceptional emulsion stability. This synthetic fiber treatment agent contains a polyoxyalkylene alkyl ether represented by the following formula (1). RO-(EO)a-[(PO)b / (EO)c]-(EO)d-H (R indicates a C1-30 alkyl group or alkenyl group, and may have either a straight chain or branched chain structure. PO represents an oxypropylene group, and EO represents an oxyethylene group. a, b, c, and d each represent an average number of added moles; a = 1-10, b = 1-10, c = 1-10, and d = 1-40. [(PO)b / (EO)c] is a polyoxyalkylene group obtained by randomly adding b moles of PO and c moles of EO.)

Description

technical field [0001] The present invention relates to a treatment agent for synthetic fibers and its use. More specifically, it relates to a synthetic fiber treatment agent excellent in product stability during low-temperature storage and excellent in emulsion stability (emulsion stability) of the treatment agent, a synthetic fiber filament yarn using the synthetic fiber treatment agent, and a pseudo Manufacturing method of twisted yarn. Background technique [0002] In recent years, the production base of synthetic fibers has expanded, and synthetic fibers are being produced in various countries and regions. Accordingly, the conditions of use of the treatment agent for synthetic fibers also involve various aspects, for example, it is desired to be able to use it in a wide temperature range. [0003] In general, synthetic fiber processing agents are mainly composed of smoothing agents such as polyoxyalkylene alkyl ethers, polyether compounds, and ester compounds. [000...
