manufacture example 1

[0203] In the 3L autoclave that can be stirred, can be adjusted in temperature, and has an alkylene oxide feed box, a nitrogen supply pipe, and a pressure regulating valve, drop 221g of C as alcohol. 14-15 Branched chain alcohol, 3.5 g caustic potash 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. Then, at a desired molar ratio, under 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 1160g of propylene oxide and 880g of ethylene oxide is put in as the second stage. In the second stage, the addition polymerization reaction was carried out for about 15 hours. Thereafter, the obtained polyoxyalkylene alkyl ether was neutralized with 5.3 g of lactic acid, and recovered. Thus, polyoxyalkylene alkyl ether (POA-1) was obtained.

[0221] In Examples 1-10, the compounding component described in Table 3 and Table 4 was mixed and stirred, and the processing agent for synthetic fibers was prepared. In addition, the polyethers 1-3 in Table 3 and Table 4 are the following polyethers.

[0222] Polyether 1: PO / EO=50 / 50, weight average molecular weight 5000 random type

[0223] Polyether 2: PO / EO=25 / 75, weight average molecular weight 2000 random type

[0224] Polyether 3: PO / EO=50 / 50 polyoxyalkylene decyl ether, weight average molecular weight 800 random type

[0225] Next, water was added to the prepared synthetic fiber treatment agent to prepare an aqueous solution having a nonvolatile content of 10% by weight. Next, the polyethylene terephthalate full-dull yarn containing 2.5% of titanium oxide, which was spouted from the metal port by the extruder and cooled and solidified, was treated by using a metering pump device to supply oil to the nozzle. 130dtex / 72f (130デシテックス / 72フィラメメント) POY is spun into an aqueo...

Abstract

The invention provides a synthetic fiber treatment agent excellent in packaging appearance and reelability. In addition, the invention also provides a synthetic filament yarn using the synthetic fiber treatment agent and a method of manufacturing synthetic fibers. The synthetic fiber treatment agent contains a polyoxyalkylene alkyl ether (A) represented by the following formula (1), the concentration of non-volatile components of the treatment agent is that the kinematic viscosity of an aqueous solution of 10 weight % at 25 DEG C is 2.0-3.0 mm2/s, R1O-(PO)a/[(EO)b]-H (1) (R1 indicates a C14 or 15 branched alkyl. PO represents an oxypropylene group, and EO represents an oxyethylene group. a and b each represent an average number of added moles; a = 1 to 100, and b = 1 to 100. [(PO)a/(EO)b] is a polyoxyalkylene group obtained by randomly adding a moles of PO and b 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 treatment agent for synthetic fibers that has a good package appearance (curl shape) and thus is excellent in unwinding properties of fibers, a synthetic fiber filament yarn using the treatment agent, and a method for producing a false-twisted processed yarn. Background technique [0002] In recent years, the production speed of synthetic fibers has been further increased. On the other hand, the production of new forms of synthetic fibers such as synthetic fibers with low denier, synthetic fibers with multiple fibers, and synthetic fibers with special-shaped cross-sections There is a tendency to gradually increase. [0003] In general, the processing agent for synthetic fibers mainly contains a smoothing agent and is composed of an emulsifier, an antistatic agent, and the like. Existing treating agents for synthetic fibers have been...
