[Industrial Application Field] The present invention relates to a processing method for preventing a silk fabric using highly twisted yarn from shrinking at each stage after processing. [Prior Art] Silk fabrics using highly twisted yarns as wefts have a unique texture at the expense of their untwisting ability, and are so-called crepe fabrics. Crepe, which is a highly twisted silk yarn fabric, shrinks considerably in width and length when it is scoured, and mechanical tentering processing is performed to return it to the standard dimensions, but the subsequent processing is still difficult. This is a major drawback as it tends to shrink during handling. Traditionally, acrylic, styrene,
Resin processing using epoxy, silicone, fluorine, urethane, melamine, glyoxal, and mixtures of these resins, processing methods using increased amounts of tin, sericin fixation, and the like have been studied. However, there are few processing methods that have focused on shrink-proofing properties, and almost no processing methods have been developed that solve the drawback of silk fabrics, which tend to shrink during various processing steps such as dyeing after scouring, and during distribution and consumption. By the way, in order to solve the above-mentioned problems, the present applicant filed a patent application (Patent Application No. 71672, 1983) for an invention called "Preshrunk processing method for silk fabrics" in March 1988.
That's what I did. The invention of the previous application is a processing method in which a highly twisted silk fabric (white fabric) after scouring is immersed in water or other solvent in a taut state and heated for a predetermined period of time.
Considerably excellent shrink-proofing properties were obtained. However, since the invention of the previous application was only at the experimental stage, if it was implemented in the actual mass production stage, the shrink-proofing properties would be considerably reduced and even stronger conditions would be required. It has become clear that scratches and scratches are more likely to occur, and that a means to prevent them is desired. [Problems to be Solved by the Invention] The present invention aims to solve the above-mentioned problems, and it has achieved excellent shrink-proofing properties even in the mass production stage, does not yellow, and has a unique wind effect using highly twisted yarn. The purpose of the present invention is to provide a shrink-proofing method that alleviates and eliminates the disadvantage that crepe with a bond shrinks during various processing stages and distribution and consumption stages, and provides shrink-proof properties that meet the needs of the recent market. [Means for Solving the Problem] As a result of various studies to achieve the above object, the inventors of the present invention obtained good results even when immersed in a relatively low temperature heating bath of 25 to 70°C at the experimental stage. However, in the mass production stage, high temperatures of 90 to 130 degrees Celsius are required, and it is also suitable to wrap it using a beam, and it must be bleached and washed to prevent yellowing and scratching. They discovered that it is desirable to add hydrosulfite as a PH regulator, and found that this processing method does not necessarily require the scouring stage, but can be used at either the white dough or gray dough stage. That is, in the present invention, a white silk fabric or gray fabric using highly twisted yarn is wrapped around a beam and heated to a temperature of 90 to 130°C under tension in a hot water bath to which a minimum amount of hydrosulfite is added as a bleaching and PH adjusting agent. The gist of this invention is a method for shrink-proofing silk fabric, which is characterized by soaking it in water for a predetermined period of time. In the method of the present invention, not only white fabrics but also gray fabrics are subject to processing, and since the shrinkage characteristics, texture, and grain characteristics differ depending on the type of silk fabric,
Depending on the situation, you can choose between white fabric stage processing and gray fabric stage processing. For example, depending on the variety, the fabric area is about 10% larger than white fabric in order to keep the woven fabric stronger and more uniformly taut.
It may be more efficient to use gray fabric with a wider area and firmer texture, as it can create stronger tension and be more efficient.
In addition, in order to prevent deterioration of texture and grain as much as possible,
In some cases, it is better to pre-shrunk the material before scouring. Note that it is desirable to conduct a preliminary test in advance to confirm whether the white cloth stage or the gray cloth stage is better. In the present invention, as described above, a white silk fabric or a gray fabric (hereinafter collectively referred to as crepe) using highly twisted yarn is subjected to a shrink-proofing process in the following steps. First, this crepe (usually 40 to 45 cm wide for gray fabric and 35 to 38 cm wide for white fabric) is evenly wrapped around a beam (perforated cylindrical roll) using a tension process. Since it is not in a loose state, it is sufficient to wrap it around the beam with a moderate amount of tension, and the degree of tension will naturally increase due to the self-contraction force that tends to contract during the immersion heat treatment. Next, the beam with the crepe wrapped in tension in this way is immersed in a heated water bath.The temperature conditions for this heating are 90 to 130℃;
If the temperature is below 130℃, the shrink-proofing effect will be low, and depending on the temperature conditions of post-processing, there is a risk that the shrinkage rate will not be suppressed.On the other hand, if the temperature exceeds 130℃, the pressure will increase, which is dangerous, and may cause yellowing. It has become so severe that it cannot be prevented. The temperature of this heating immersion is 20 to 40 minutes, usually about 30 minutes is sufficient; if it is less than 20 minutes, the shrink-proofing effect will be slightly reduced, and if it is immersed for more than 40 minutes, the effect will not change much. In the present invention, the reason why the preshrunk is wrapped around the beam is that the woven fabric, each 10 meters long, is kept under strong tension in a hot water bath at the above temperature (the tension becomes stronger when heated).
In order to keep the temperature compact, it is difficult to use a flat bed type tenter system, and a high pressure cooker is required to create hot water bath conditions of over 100℃, so a compact beam type tenter method is suitable. be. Furthermore, by forming the material into a beam shape, it is possible to process multiple sheets at the same time, and there is also the advantage that it is easy to adjust the vertical tension when winding the material into a beam. The above-mentioned shape is usually preferably about 20 to 30 cm in diameter and 45 to 50 cm in height.
~55% is desirable. Furthermore, it is necessary to add hydrosulfite to the hot water bath in the present invention, and the reason for this is as follows.
This is because silk fabrics generally tend to yellow when subjected to high-temperature treatment, so it is necessary to prevent this yellowing and maintain whiteness. Note that the reductive bleaching mechanism of hydrosulfite is based on the following formula. H 2 SO 3 +O→H 2 SO 4 H 2 SO 2 +O 2 →H 2 SO 4The amount of hydrosulfite added may be the minimum amount, and is usually about 0.25 to 0.5%. In addition, the addition of this hydrosulfite makes the pH in the bath slightly acidic, around 6.0, which alleviates the increase in pH caused by soap and alkaline content contained in the white fabric, and prevents overscouring and scratches on the alkaline side. The occurrence of this can be prevented to some extent. Although the method of the present invention is as described above, it is desirable to appropriately adjust the water bath temperature and the tension of wrapping around the beam depending on the type of silk fabric. In other words, there are varieties of chirimen such as Ichikoshi, Kodai, Kawari Ichikoshi, Kawari Mitsukoshi, Kawari Kodai, and Shinonome, but each uses different threads such as twisting and weaving, and weaving techniques, so the shrinkage characteristics and The texture and grain characteristics are different, so it is desirable to find processing conditions that are appropriate for each product type. Suitable results can be obtained by selecting an appropriate processing temperature. [Function] When the processing method of the present invention having the above-mentioned configuration is applied to crepe at the mass production stage, the originally significant shrinkage shrinkage changes to crepe with a small shrinkage rate, and an excellent shrinkproof effect is achieved. be. For example, Ichikoshi and Kodai pre-shrunk products use particularly strong high-twist yarns, so the horizontal shrinkage is large and can shrink by 20-25% if untreated.
Products processed according to the present invention have a shrinkage rate of 11 to 12% depending on the conditions. In addition, other types such as Ichikoshi, Mitsukoshi, Kodai, Shinonome, etc. have even better shrink resistance. The reason why the processing method of the present invention exhibits such an excellent shrink-proofing effect is thought to be that the strain in the structure is relaxed, and the untwisting torque of the twisted yarn causes misalignment of the fiber micelles in the twisting direction. However, this is promoted by the intrusion of water molecules and the temperature effect, making it difficult to shrink. In addition, in the method of the present invention, by adding hydrosulfite as a bleaching agent, the whiteness is high and almost the same as that of unprocessed products even if the processing temperature conditions are quite strong. Yellowing is completely prevented. As mentioned above, the action of hydrosulfite makes it easier to prevent scratches, but it goes without saying that this prevention of scratches also prevents the occurrence of thread flaws and fluffing. [Example] Processing (a) Processing conditions: white fabric, temperature 100°C (normal pressure) 12 pieces of each of the 6 types of crepe white fabric shown in Table 1 were
~16m (1 roll) was used to perform the following processing. Each beam with a diameter of 250 mm, a height of 500 mm, and a porosity of about 50% was wrapped with crepe uniformly under slight tension, and placed in a 100℃ water bath (normal pressure cooker) with 0.5% hydrosulfite added. Soaked for 30 minutes. Note that the slight tension means that the white fabric stretches easily, so it should be rolled just enough to avoid wrinkles. After the immersion, the material was rewound to a suspended kneaded state for texture adjustment, washed lightly in a very dilute soap bath, and then finished in the usual manner. Processing (b) Processing conditions: white fabric, temperature 120°C (high pressure) Six types of crepe white fabric were used in the same way as in processing (a), but only the temperature was changed to a 120°C water bath (high pressure cooker). Other than that, everything else was processed under the same conditions as in processing (a), and the same sorting and finishing was performed. Processing (c) Processing conditions: Gray fabric, temperature 100℃ (normal pressure) As in processing (a), using six types of gray fabric that have not yet been scoured, similar beams were uniformly processed while applying a slight tension. Wrap it in a 100℃ water bath (normal pressure cooker) with 0.5% hydrosulfite added.
It was soaked for 30 minutes, followed by normal scouring and finishing. Processing (d) Processing conditions: Gray fabric, temperature 120℃ (high pressure) Using the same six types of gray fabric as in processing (c), only the temperature was changed to a 120℃ water bath (high pressure cooker).
Everything else was processed under the same conditions as in processing (c), and the same scouring and finishing was performed. Shrinkage tests and whiteness measurements were conducted for the above processing (a) to (d). (a) Shrinkage test results The shrinkage percentage of each crepe obtained in processing (a) to (d) was determined by JIS-L.
-Measured using the 1042A method. For comparison, the shrinkage rate was also measured for unprocessed (white fabric). These results are shown in Table 1.

[Table] From Table 1, it can be determined that the shrinkage rate of each product type can be significantly suppressed depending on the processing conditions. Ichikoshi and Kodai, which use strong twist yarns that have a high shrinkage rate, have somewhat low shrink resistance, but it is thought that this can be further improved by adjusting the tension of wrapping around the beam. Because the weaving techniques of Kawari Ichikoshi and Kawari Mitsukoshi are similar, they exhibited almost the same shrink-proof properties, and the shrinkage rate was reduced to about half. For Shinonome and Kojiro Kodai, processing (d) dramatically improved the shrinkage rate, but at the same time the texture and grain decreased, so it was judged that milder processing conditions were appropriate. (b) Whiteness measurement results The whiteness of each crepe and unprocessed white fabric obtained by the above processing (a) to (d) was measured using Hunter Lab of JIS-Z-8730.

[Table] From Table 2, there is almost no overall decrease in whiteness due to the processing according to the present invention, and only a very slight decrease in whiteness is observed in processing (d) using gray fabric. In addition, when the reduction rate was measured for samples processed by each process, almost no difference was observed depending on the process. [Effects of the Invention] An effect of the present invention is that the ``easiness to shrink'', which is considered to be a major drawback of silk fabrics using highly twisted yarns, is alleviated and eliminated by a relatively simple processing method. In other words, the method of the present invention is simple and highly effective as a method for preshrinking silk fabrics, and is useful as a practical method without any chemical disadvantages.
Moreover, it has been confirmed that the present invention can be implemented in the actual mass production stage, and its effects will be immediately exerted on the silk textile industry. In addition, in the method of the present invention, the shrinkage rate, texture, and grain will vary depending on the processing conditions, so
It is important to determine the processing conditions that will yield commercial value for each type of product, and further improvement in effectiveness can be expected by considering the use of low-tension finishing and flexible processing in combination.
