The present invention relates to a method for high-temperature scouring of polyester fibers. Polyester fibers are generally scoured at temperatures below 100°C for knitted or woven fabrics, but in order to improve dyeability and texture, polyester fibers, especially highly twisted woven fabrics, are scoured at temperatures below 100°C. Graining and relaxing processes are essential to increase added value, and scouring at 100°C or higher has been proposed for these purposes. At this time, if a normal surfactant is used for scouring, air bubbles are generated during the process, resulting in insufficient graining, unsatisfactory relaxation, and poor dyeability. Moreover, when the temperature exceeds 100°C, the pressure becomes high, so air is removed, but highly foamy products exhibit rapid foaming, which can cause trouble. The present inventors have arrived at the present invention as a result of intensive research into a high temperature scouring method at 100°C to 180°C. That is, the present invention uses polyester fibers.
At a temperature of 100℃ to 180℃, general formula R-O-(EO)n(PO)mH [R: alkyl group with 8 to 36 carbon atoms, 6 carbon atoms]
Alkylaryl group having ~30 alkyl groups, EO: oxyethylene group, PO: oxypropylene group n: an integer of 4 to 50 m: an integer of 1 to 50, provided that n≧m] A nonionic surfactant represented by The present invention provides a method for high-temperature scouring of polyester fibers, which comprises scouring polyester fibers in an aqueous system containing the following. Generally speaking, in the case of polyester hard-twisted fabrics, in order to improve the weaving properties during the weaving process, polyacrylic acid glues with high fluffing effects, esterified oils with smoothness, silicone oils, mineral oils, paraffin oils, etc. are used. As the focusing coating resin, water-soluble polyacrylic resins, water-soluble polyester resins, water-soluble polyamide resins, water-soluble polyurethane resins, etc. are used in combination or alone. In order to effectively remove these substances, scouring is generally carried out at 100°C or lower using an anionic, amphoteric, or nonionic surfactant in combination with an alkaline agent. However, processed yarn fabrics using highly twisted yarns require high-temperature conditions of 100℃ to 180℃ to fully untwist them, and package-type liquid jet scouring machines are used at low bath ratios to save energy. Currently, this is becoming more and more common. In this case, a low foaming surfactant is indispensable because the foaming property of the surfactant causes air to be drawn in and cause the flow rate to decrease. In addition, in order to achieve sufficient texturing, a mechanical beating effect is required at a low bath ratio, and surfactants with high foaming properties are not effective in this respect as well. However, polyester fiber fabrics contain the aforementioned water-insoluble oil and sizing agent, and require a surfactant with high emulsifying power. As a result of investigation, we found that surfactants with low foaming properties, strong emulsifying power, and do not separate in a scouring bath at temperatures of 100°C to 180°C have a carbon number of less than 8 in the alkyl group in the general formula above. When the number of carbon atoms in the alkyl group is larger than 36, or when the number of carbon atoms in the alkyl group is larger than 30, the penetrating power is high, but the emulsifying power is low. Larger alkylaryl groups showed poor water solubility and a tendency to separate. When the number of moles of propylene oxide added was greater than the number of moles added of ethylene oxide, the water solubility was similarly poor and there was a tendency for separation, and the detergency was also poor. The total number of moles of ethylene oxide added (n) and the number of moles of propylene oxide added (m) varies depending on the molecular weight of R, and generally, the larger R is,
The larger the number of n+m, the better the low foaming property and detergency. The reason why the compound represented by the above general formula exhibits excellent performance at high temperatures is not clear, but it is presumed that it lies in the balance between the penetrating power at low temperatures and the emulsifying power of oil at high temperatures. The reason for this is that R has 8 carbon atoms, which has higher penetrating power.
In the case of a smaller alkyl group, or in the case of an alkylaryl group in which the alkyl group has fewer than 6 carbon atoms, rapid expansion of the sizing agent occurs at a lower temperature to assist the permeability of the caustic soda used in combination. Judging from the fact that insoluble resins and oil agents are taken in, there is a tendency for darkening and poor dyeing properties.According to the above general formula compound, there is a certain degree of penetrating power, and by gradual untwisting, It is thought that it is better to emulsify and disperse the oil while forming the grain. It is well known that the compound represented by the above general formula has a clouding point, but since it does not separate even at high temperatures set to 100°C or higher, the compound represented by the general formula has a higher clouding point. There is no problem in adding alkyl polyethylene glycol, alkylaryl polyethylene glycol, amphoteric surfactant, and anionic surfactant to the extent that they do not impair low foaming properties. The present invention will be specifically explained below using examples. Example 1 Using the surfactants shown in Table 1, a temperature of 130
Table 1 shows the results of tests regarding emulsifying and foaming properties at ℃. In addition, for the emulsifying test, 1 g of oil/
1. After adding 1 g/1400 c.c. of surfactant and heating to 130°C, the emulsified state was observed. Evaluation method ○: Shows a cloudy, stable emulsified state, with no separation observed at all. △: Shows a cloudy and stable emulsified state, but separation and oil droplets are observed. x: Separation occurs without emulsification at all. Example 2 Using various surfactants shown in Table 2 and a commercially available high temperature and high pressure rotary washer model FW-100 [manufactured by Fukushin Kogyo Co., Ltd.], 300 kg of polyester strongly twisted yarn fabric and surface active Using 2 g/1 of agent and 2 g/1 of caustic soda (solid) at a bath ratio of 1:10, the drum was rotated 15 times, the temperature was increased from 50°C to 3°C/min, and after 30 minutes at 130°C, it was cooled. Table 2 shows the results of tests on graininess and scouring properties.
