The present invention relates to a method for reducing weight of a polyester fiber structure by treating it with an alkaline solution. More specifically, a specific alkyl sulfate or alkyl sulfate ethylene oxide adduct and a lower alcohol are used in combination with the alkali solution to increase the permeability of the alkali solution into the polyester fiber structure and to perform a uniform alkali weight loss process. Regarding the method. In recent years, in order to improve the feel of polyester fiber fabrics and bring them closer to silk-like textures, a method has been widely adopted in which the fabrics are treated with an alkaline solution to decompose and remove some of the polyester fibers to reduce their weight. In addition, the method ranges from the batch method, such as the hanging kneading method, in which the polyester fiber fabric is immersed in an alkaline solution for a long time to decompose and reduce the weight, to the method in which the alkaline solution is attached to the fabric by a padding method, etc., and then heat treatment is performed. It is well known that there is a shift to a continuous method that can save labor and energy by decomposing and reducing the weight. However, one drawback of continuous methods such as this padding method is that it is necessary to use a highly concentrated alkaline solution, which increases the surface tension of the alkaline solution, resulting in poor wetting and permeability, which often results in uneven weight loss. This causes uneven color and texture. In order to solve these problems, conventional methods have been used to lower the surface tension of the alkaline liquid by adding lower alcohols such as methanol or ethanol or sodium alkylsulfonate to the alkaline liquid, but these methods have not been satisfactory. No effect has been obtained. In addition, as penetration aids when cellulose fibers are mercerized, alkali salts of phosphinic acid (Japanese Unexamined Patent Application Publication No. 49-48995), sulfoxide compounds (Japanese Patent Publication No. 47-6598), and alkali salts of olefinsulfonic acid (Unexamined Japanese Patent Publication No. 47-6598) are used. Methods using methods such as 187097/1982 have also been proposed, but when used for reducing the weight of polyester, all of these methods have poor alkali compatibility. It is not practical because it has some disadvantages such as inhibiting the weight loss effect, having strong foaming properties, and having poor penetration effect. The present inventors have conducted extensive research to solve these problems, and have found that in the alkali weight loss treatment of polyester fiber fabrics, that is, in continuous methods such as the padding method, in order to uniformly apply an alkaline solution to the fabric, It is necessary to use a penetrant that is highly compatible with alkali, has excellent penetration effects, and does not inhibit the weight loss effect, and specific alkyl sulfates or alkyl sulfate ethylene are used as penetrants with such properties. The present invention was achieved by discovering that a mixture of an oxide adduct and a lower alcohol is suitable. That is, the present invention provides a method for reducing the weight of a polyester fiber structure with an alkali solution, in which at least one compound of the following general formulas [] and [] and a compound of the following general formula [] are added. The present invention relates to a method for continuous weight loss of a polyester fiber structure, characterized in that the fiber structure is subjected to a weight loss treatment using an alkaline solution having a concentration of at least 5% by weight while running the fiber structure. [] C n H 2n+1 OSO 3 M [] C o H 2o+1 O (CH 2 CH 2 O) p SO 3 M [] C q H 2q+1 OH (However, in the formula, M: periodic law Table Group 1 alkali metals, m=4-10, n=4-10, p=1-3, q
= 1 to 6) As the polyester fiber structure in the present invention, fabrics such as knitted fabrics and nonwoven fabrics made of polyethylene terephthalate and copolyester thereof are generally used, but they are not particularly limited to these. This applies to all polyester fiber structures that can be decomposed and reduced in weight by alkaline solutions. The alkaline solution used for weight loss treatment is typically caustic soda or an aqueous solution of caustic potash, and its concentration depends on the structure and fineness of the fabric being treated, the degree of softness targeted, and the treatment conditions. Although there are differences depending on (temperature, time), usually 5
~50% by weight, preferably 10-30% by weight. The present invention is based on the general formula [],
It is characterized by the combined use of at least one of [ ] and the compound shown in [ ] as a penetrant, which significantly lowers the surface tension of the alkaline solution and improves the permeability of the alkali solution into the fabric. It is high and can be penetrated uniformly in a short time. Furthermore, since there is no effect of accelerating or inhibiting the rate of weight loss of polyester fibers caused by alkaline solution, there is also the advantage that control of alkali weight loss is extremely easy and work is easy. The content of the penetrant represented by the general formula [ ] or [ ] used in the present invention is generally based on the total weight of the alkaline solution.
Must be at least 0.1% by weight, 0.3-1.0% by weight
A range of is particularly preferred. If the content is too low, the surface tension of the alkaline solution will not be lowered, and if the content is too high, the disadvantage is that the effect corresponding to the content cannot be obtained. Further, it is preferable to use the lower alcohol represented by the general formula [] in an amount of 3 to 10% based on the total weight of the general formula [] or the compound represented by [] in terms of penetration, antifoaming effect, and efficiency. Furthermore, the carbon numbers of the compounds of the general formulas [], [], [] specified in the present invention are m, n = 4 to 10, p = 1 to 3, respectively.
q must be in the range of 1 to 6, and compounds outside this range have some disadvantages such as poor penetration effect, inhibiting weight loss effect, and excessive foaming. cannot be achieved and is not desirable. As M (alkali metal of Group 1 of the periodic table) shown in formulas [] and [], sodium and potassium are generally used, and sodium is preferably used industrially. A few specific examples of compounds of formula [] are C 4 H 9 OSO 3 Na, C 6 H 12 (C 2 H 5 )
Representative examples include OSO 3 Na and C 8 H 17 OSO 3 Na. A few specific examples of compounds of formula [] are:
C 4 H 9 OCH 2 CH 2 OSO 3 Na,
C 8 H 17 OCH 2 CH 2 OSO 3 Na, C 8 H 17 O
Examples include (CH 2 CH 2 O) 2 OSO 3 Na. Among the compounds represented by the formula [], examples of compounds preferably used include methanol, ethanol,
Examples include butyl alcohol and isopropyl alcohol, with butyl alcohol being particularly preferred. The continuous weight loss method for polyester fiber structures of the present invention is carried out by continuously dipping the fabric in an alkaline solution bath and squeezing it uniformly, or by continuously and uniformly spraying or applying an alkaline solution onto the fabric, and then Continuous steam method B in which the fabric is heated in a steamer at 100°C to 160°C to decompose and lose weight Continuous curing method in which the fabric is heated in a heating cylinder or hot air drying device at 80°C to 150°C to decompose and lose weight (an amount commensurate with the desired weight loss rate) is applied to a method of continuous deposition followed by decomposition and weight loss, since sufficient penetration effect can be obtained in a short period of time, which is effective. As described above, according to the method of the present invention, it is possible to uniformly infiltrate the polyester fabric with an alkaline solution in a short time, thereby improving productivity and making it possible to perform a high-quality weight loss treatment without uneven weight loss. In particular, the effect of the present invention is remarkable for fabrics such as high-density fabrics and highly twisted fabrics, which are difficult to penetrate with alkaline solutions and are prone to uneven weight loss. The method of the present invention will be explained in detail with reference to Examples below. Example 1 Methanol and commercially available penetrant A (main component: sodium alkyl sulfonate), commercially available penetrant B (main component: phosphate ester),
A solution to which 1.0% by weight of each commercially available mercerizing penetrant C (main component phosphonic acid derivative) was added;
Butyl sulfate (C 4 H 9 OSO 3 Na), octyl sulfate ethylene oxide adduct (C 8 H 17 OCH 2 CH 2 OSO 3 Na) and butyl alcohol (C 4 H 9 OH) were mixed in a ratio of 1:1:0.1. The solution mixed in proportion to the total weight of 20% alkaline solution
Create a solution containing 0.5% by weight, and check (1) Stability of alkaline solution (left at room temperature for 24 hours) (2) Foaming property of alkaline solution (measurement of defoaming time after shaking the solution under certain conditions) ) (3) Permeability of alkaline solution (vertical, horizontal, 75D-
Alkaline solution is applied with a syringe needle onto a twill fabric made of 24F polyethylene terephthalate fibers.
Table 3 shows the performance test results for three items: 0.005 cc was dropped and the time taken for it to be absorbed into the fabric was measured.

A 17.5% caustic soda solution was used as the alkaline solution, and 0.5% of the mixed solution of alkyl sulfate and butyl alcohol, the penetrant of the present invention used in the experiment of Example 1, was added to the alkaline solution.
% by weight was added. The Desine crepe fabric was passed continuously through this alkaline solution, and then squeezed with a mangle to remove excess alkaline solution, and then introduced into a continuous steam zone where it was steamed at 105° C. for 3 minutes. Next, the fabric was washed with water and dried, and the weight loss rate of the fabric was examined, and it was confirmed that the weight loss rate was 18%. Subsequently, the fabric was dyed and finished using a conventional method, and as a result of inspection, no uneven hue or texture due to uneven weight loss was observed, and the finished product had a good silk-like texture. For comparison, we used only alkaline solution and the commercially available phosphate ester penetrant B used in the experiment in Example 1 instead of the penetrant of the present invention, and the other conditions were exactly the same as above. When fabrics were processed and inspected, it was found that the fabrics treated with only caustic soda had uneven hue and texture over the entire fabric due to uneven weight loss, while the fabrics treated with commercially available penetrant B had an average of 11 Abnormal areas due to uneven weight loss were observed in several locations/50m.
