The present invention relates to desizing agents. More specifically, the present invention relates to a high performance desizing agent for textiles. Recently, polyvinyl alcohol and acrylic ester-based sizing agents have been frequently used as sizing agents for fibers. These glues change in quality over time and heat treatment, and end up sticking to the fibers. These stuck substances are difficult to remove during desizing scouring performed before the dyeing process, and cause various problems such as uneven dyeing during the dyeing process. At present, desizing methods that are relatively effective include a method using sodium bromite, a method using peroxide treatment, a method using an alkyl ether nonion and an alkylbenzene sulfonate,
There are methods using alkylaryl type nonions and alkyl ethoxy sulfate salts, but even after a long desizing process at high temperatures, complete desizing is not possible, and energy and water conservation has become an issue in the textile processing industry. However, there was a strong desire to develop a higher performance desizing agent. As a result of intensive studies to obtain a high-performance desizing agent, the present inventors found that the compounds shown below are extremely effective, and thus arrived at the present invention. The desizing agent of the present invention contains 20 to 100% by weight of the compound represented by the general formula () and 80 to 0% by weight of other surfactants or higher fatty acids. (However, R 1 is an alkyl group, alkenyl group, or alkylaryl group having 6 to 36 carbon atoms; A is an alkylene group having 3 to 4 carbon atoms; R 2 is an alkyl group or alkenyl group having 5 to 35 carbon atoms; a is 5 to 50, and b is a number of 3 to 70.) Here, the alkyl group, alkenyl group, or alkylaryl group having 6 to 36 carbon atoms represented by R1 is hexyl, heptyl, octyl, nonyl, decyl. , lauryl, myristyl, cetyl, stearyl, oleyl, behenyl, lanolin alkyl, octylphenyl, noniphenyl, dinoniphenyl, etc., are residues of alcohols or alkylphenols having natural or synthetic straight or side chains, and R 2 The acyl group possessed is a residue of a fatty acid such as caproic acid, caprylic acid, capric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid, linoleic acid, linoleic acid, behenic acid, and lanolin fatty acid. (AO) The moiety represented by a is a mole adduct of propylene oxide, butylene oxide, isobutylene oxide, tetrahydrofuran, etc. alone or in a mixture thereof. The number of added moles a of (AO) is 5 to 50
is preferable, and the number b of added moles of ethylene oxide is preferably 3 to 70. The addition method of these alkylene oxides may be either random or block, but the range of the addition amount is important, and good desizing effects cannot be obtained outside the range shown in the present invention. The compound of the general formula () used in the present invention can be produced by a known method, by adding a predetermined amount of an alkylene oxide having 3 to 4 carbon atoms and ethylene oxide to a monohydric alcohol or alkylphenol having 6 to 36 carbon atoms. It is a compound obtained by further esterifying the compound obtained by addition with a fatty acid having 6 to 36 carbon atoms. Any compound of the general formula () within the range shown in the present invention can be used as a desizing agent, but when workability is taken into account, the general formula ( ) and a compound of general formula () in which the ethylene oxide chain portion accounts for 20 to 50% by weight of the total molecular weight in a weight ratio of 1:5 to 2:1. It is particularly preferred because foaming inside is extremely small and foaming is prevented even in other steps. The desizing agent of the present invention must contain 20% by weight or more of the compound represented by the general formula (), and if the content is too small, the desired effect cannot be obtained. The desizing agent of the present invention may contain other surfactants or higher fatty acids in addition to the compound of general formula (), but the content thereof is preferably 80% by weight or less. Other surfactants include anions such as alkylbenzene sulfonates, alkyl sulfate ester salts, polyoxyethylene alkyl ether sulfate ester salts, dialkyl sulfosuccinate ester salts, alkanesulfonates, alkyl phosphate ester salts, and higher fatty acid salts. Surfactants: nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, sorbitan fatty acid ester, glycerin fatty acid ester; amphoteric surfactants such as alkyl betaine and alkyl glycine. Higher fatty acids include caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, and linolenic acid, which form salts in aqueous alkaline solutions to increase surface activity. show. The desizing agent of the present invention is preferably used at a desizing agent concentration of 0.02 to 2% by weight in an alkaline aqueous solution at a temperature of 30 to 100°C. When the desizing agent of the present invention is used, it is possible to perform almost complete desizing in a shorter time than with conventional products. That is, the processing time of the present invention is 1~
5 minutes is sufficient, which is less than half the time (about 1/10) of the 20 to 40 minutes required by conventional methods. In addition, since the process temperature of the present invention is sufficient at around 60°C, the amount of steam used is less than half that of the conventional method, which is carried out at around 80°C to 100°C.
It can also have great effects in terms of energy conservation and resource conservation, which are much talked about today. Examples will be given below to explain in more detail. Example 1 A desizing test was conducted on a polyester fabric using the method shown below. Method A: Put the desizing agent of the present invention shown in Table 1 into two beakers.
Take 0.5g, add 1 part of water at 60℃, dissolve, and make 3cm
Prewashing was performed for 30 seconds using a 3 cm x 3 cm test cloth*. In a separate container, dissolve 2 g of the desizing agent of the present invention and 2 g of caustic soda shown in Table 1 in 1 part of water at 60°C, soak the pre-washed test cloth, and stir for 2 minutes to perform desizing treatment. I did it. Next, the test cloth was taken out and washed three times in hot water at 60°C for 30 seconds each. Comparative Examples Nos. 9 to 11 were treated in the same manner as above. Method B (comparative example using sodium bromite) Using the same test cloth as in method A, prewashing was performed with water at 60° C. for 30 seconds. In beaker 2, add 5g of sodium bromite, 2g of soda ash, and 1g of Prisco M ** .
It was dissolved in water 1 at 100°C, a prewashed test cloth was immersed in it, and the mixture was stirred for 20 minutes while maintaining the temperature. Next, it was immersed in a solution of 5 g of sei soda dissolved in 1 part of water at 90°C, and stirred for 5 minutes while maintaining the temperature. Then, as in Method A, hot water washing was performed three times. *Test fabric: unrefined polyester fabric treated with acrylic ester glue. **Prisco M: Penetrant that does not consume effective bromine (manufactured by Ipposha Yushi Co., Ltd.). Measurement of desizing effect The test cloth that was desizing using Method A or Method B was
It was dyed using a red cationic dye that does not dye the polyester cloth but only dyes the glue, washed with water, and dried. Next, using a spectrophotometer, at a wavelength of 550 mμ,
The reflectance (%) of each test fabric was measured, setting the undyed fabric as 100. The larger the value, the greater the desizing effect. As a cationic dye, Kaya Acrylic Brilliant Pink B (manufactured by Nippon Kayaku Co., Ltd.)
was used. Table 1 shows the test results.
