The present invention relates to a method for treating dyed polyester fibers. Polyester fibers, whose main component is polyethylene terephthalate, have better clothing properties than other synthetic fibers and are used in a wide range of clothing applications. Disadvantages such as poor color development have been pointed out. In particular, the improvement of color development is an important issue in many fields where it competes with silk, which has good color development, and is therefore being actively researched by related parties. From the perspective of raw yarn, polymers have been developed that are modified to be dyeable with cationic dyes, and some have improved in terms of color development, but this type of modified polyester has poor dye fastness and poor clothing properties. However, the properties of polyester are insufficient and the original properties of polyester are not maintained, so it has not yet been widely used. The present inventor focused on the above-mentioned problem of coloring properties of polyester fibers, and completed the present invention after extensive research. The purpose of the present invention is to provide a processing method that improves the color development of dyed products without impairing the excellent properties of polyester fibers.
The above purpose is to treat a polyester fiber dyed product using a disperse dye with a solution containing a hydrosulfite reducing agent and a strong alkali to hydrolyze the skin layer of the dyed product by 5 to 35% by weight. This is achieved by The present invention will be explained in detail below. Generally, when polyester fibers are dyed with disperse dyes, a reduction cleaning treatment is applied after dyeing in order to improve the dye fastness, but this treatment is intended to remove unfixed dyes adhering to the outer skin of the fibers. be. For example, a solution containing 0.5 to 2 g of caustic soda (solid), 0.5 to 2 g of hydrosulfite, and 0.5 to 2 g of surfactant is treated at 75 to 85°C for about 5 to 15 minutes, which causes hydrolysis of the fibers. The conditions are not strong enough to cause any damage, and therefore hardly change the hue of the dyed product. In addition, for the purpose of creating a silk-like texture for polyester fibers or a soft texture for fabrics, the skin layer of the fibers may be hydrolyzed with a strong alkaline solution before dyeing. The impact on this is relatively small. Hydrolyzing fibers using a strong alkali after dyeing, as in the method of the present invention, is thought to be accompanied by discoloration due to a large amount of dye falling off, and is a method that has been avoided as common knowledge. There is no known phenomenon in which the color changes sharply and sharply or deeply, and the inventors were surprised by this unique phenomenon and effect. For example, disperse dye Sumikaron Blue S-BG
(manufactured by Sumitomo Chemical), 1% based on the fiber weight,
Fabrics that were dyed at different concentrations of 3%, 5%, and 10% and then reduced and washed, and fabrics that were dyed in the same way and then hydrolyzed to approximately 20% by fiber weight using the method of the present invention were tested using a Hunter color difference meter. Measure color with L, a, b
Find the value of. When the relationship curves between the saturation (√ 2 + 2 ) and the lightness (L) are drawn, as shown in FIG. 1, the curves are for the method 1 of the present invention and the conventional method 2 in which reduction cleaning is performed after dyeing. It can be said that the higher the saturation is, the clearer the image is at the same brightness, so clearly the fabric treated by the method of the present invention has better clarity. Furthermore, when we measure the color of a fabric that has been treated with a strong alkaline solution before dyeing to hydrolyze approximately 20% of the fiber weight, dyed in a similar manner, and then reduced and washed, we get the curve 3 in Figure 1, which is similar to the method of the present invention. There is no sharpness improvement effect. It is not clear why the method of the present invention gives dyed products a clear or deep color, but when polyester fibers are subjected to high-temperature hydrothermal treatment such as in the dyeing process, oligoesters migrate from the inner layers of the fibers and a considerable amount of the dyed products reach the epidermal layer. Both this oligoester and some undyed dye that remains even after reduction washing can become factors that inhibit color development. It is presumed that the effect of the method of the present invention is due to the complete dissolution and removal of these color development inhibiting substances. The problem of dye shedding when applying the treatment of the present invention can be kept to a relatively small amount by optimizing the concentration and temperature of the treatment agent, and if dyeing is carried out with the amount of shedding taken into account in advance, it is possible to dye the dye for the desired purpose. It is not that difficult to dye it to the desired hue. Reducing agents are also very effective in preventing dyes that have fallen off during processing from re-adhering to the fibers and impairing sharpness. Various known reducing agents for hydrosulfites used in the present invention can be used, and representative examples include hydrosulfites such as Na 2 S 2 O 4 and ZnS 2 O 4 and NaHSO 2 .CH 2 O・2H 2 O, Zn
(OH) HSO2CH2O , Zn( HSO2CH2O ) 2 ,
Examples include formaldehyde sulfoxylic acids such as ZnSO 2 .CH 2 O.H 2 O. The amount to be used varies depending on the density of the dyed product and the dye used, so it is difficult to define it unconditionally, but it is usually in the range of 0.5 to 20 g/. In addition to hydrosulfites, reducing agents include relatively unstable hydrogen compounds such as hydrogen sulfide and sodium borohydride, alkali metals,
There are many salts of highly electropositive metals such as aluminum and zinc, or their amalgams, and salts of metals in a low atomic state such as iron () and tin (). Hydrosulfites are also suitable as materials. Typical alkalis include caustic soda and caustic potash. The concentration to be used varies widely depending on the concentration of the dyed product, the dye used, the processing process, and the type of machine, and it is difficult to define it unconditionally. For example, (1) the fabric is immersed in an alkaline solution for a certain period of time,
In the soaked batch method, which reduces the amount by decomposition, it is 10 to 200 g/,
Desirably at a concentration of 15 to 60 g/2) After the fabric is continuously immersed in an alkaline solution and squeezed uniformly, or after the fabric is continuously and uniformly sprayed or coated with the alkaline solution, A: Continuous steam method B: Heating in a steamer to decompose and reduce weight Continuous curing method C: Heating with a heating cylinder method or hot air dryer to decompose and reduce weight C: Cold batch method where the weight is decomposed and reduced by being wound on a roll It is preferable to use the amount in the range of 50 to 300g/. The treatment temperature and treatment time for the immersion batch method are room temperature ~
100℃, preferably 60-100℃ for 15-180 minutes, continuous steam method: 95-160℃, preferably 100-145℃
for 30 seconds to 10 minutes, continuous curing method is 100 to 150
℃, preferably 110 to 130℃ for 30 seconds to 5 minutes, cold batch method room temperature to 100℃, preferably 40 to 70℃
Select the condition within the range of 8 to 48 hours. It is important that the conditions applied are capable of giving a hydrolytic loss of 5 to 35% relative to the fiber weight. In addition to the above-mentioned conditions, in the dyeing method, there are also
Lauryl dimethyl benzyl ammonium chioride Quaternary ammonium salt compounds such as 0.5 to 10 g/
Although it may be used to some extent, the effect of improving clarity is not particularly impaired in this case either. In short, it is sufficient to adopt conditions that result in hydrolysis and weight loss of 5 to 35% by weight. The polyester fibers used in the method of the present invention include ethylene terephthalate units, butylene terephthalate units, cyclohexane 1,4-dimethyl terephthalate units, ethylene 2,6-naphthalene dicarboxylate units, P-ethyleneoxybenzoate units, ethylene 1,2- (Phenoxyethane)
It is a fiber made of polyester containing 80 mol% or more of either P or P'-dicarboxylate units. Fiber structures to which the method of the present invention can be applied include filament yarns and spun yarns such as raw silk, real twisted yarn, false twisted yarn, interlaced yarn, mixed yarns of long and short fibers, and knitted fabrics and nonwoven fabrics made of these yarns. This includes fabrics such as. Next, the reason why the degree of hydrolysis of dyed products is limited to 5 to 35% by weight (hereinafter referred to as weight loss rate) in the method of the present invention will be explained using reference experimental examples. Reference experiment example A twill structure fabric made of polyethylene terephthalate yarn of 75D-24F in vertical and horizontal directions was subjected to normal scouring and heat setting, and then disperse dye Dianix was applied.
Black HG-FS (manufactured by Mitsubishi Kasei) was dyed at 130℃ for 60 minutes at a concentration of 15% of the fiber weight, and then treated with the method of the present invention to achieve the weight loss percentage shown in Table 1 to obtain a black color. The depth of flavor was compared. The treatment according to the present invention is a immersion method at 100°C in a solution containing 30 g of caustic soda (solid)/5 g of hydrosulfite. The degree of weight loss was controlled by the length of treatment time. After dyeing, those with a weight loss rate of 0% were subjected to reduction cleaning treatment at 80°C for 15 minutes with a solution of 2 g of caustic soda (solid), 1 g of hydrosulfite, and 1 g of non-ionic activator, giving a deep black color. The L value (lightness) was applied as the value. The smaller the L value is, the deeper the taste can be determined, and it corresponds well to the sensory evaluation. All of the products that lost weight in the range of 5 to 35% had a lower L value than those that did not lose weight, resulting in a deeper black color, but the most noticeable effect was achieved when the weight was reduced in the range of 10 to 25%. be. If the weight is reduced by more than 35%, the dye will fall off and become finer, making it impossible to see the deep black color.
