According to one embodiment of the present invention, the silk / rayon combined yarn of the silk yarn 21 dx 2 bonded yarn and the rayon 75 d is related.

The joint yarn generally means a yarn in which a plurality of single yarns are twisted together to form a twisted yarn. In the present invention, the joint yarn provides a double yarn twist yarn in which the silk yarn fixing yarn and the rayon yarn are joined together.

The silk thread is a thread drawn out of the cocoon, which means a thread which is not processed by refining or twisting. When silk life and death is oxidized in the air, the surface is covered with sericin, which is glossy and stiff. For this reason, refining with soapy water or the like and removing it removes only fibroin, which is used as a kneaded yarn because it has a specific luster and softness.

In the present invention, the fixing yarn of the silk yarn is used, and the fixing yarn means that the silk yarn is subjected to sericin fixing. Sericin fixation refers to a processing method in which silk sericin is chemically treated to change its solubility to coagulate closely to fibroin. A typical sericin fixing method is a method in which a yarn or fabric is immersed in a solution of sericin fixing agent to fix the whole.

The above-mentioned rayon is a fiber obtained by chemically modifying wood or cotton waste to chemically dissolve pulp made of pure fiber, and then solidifying it into a fiber. It feels soft and cold and has a strong metallic luster. It has low water resistance and good wrinkles.

In the process of manufacturing the combined yarn of the fusing yarn and the rayon of the silk yarn, a lot of cuts occurred in the initial stage. However, the present inventors adjusted the various yarn conditions so that the tension adjustment and the flexing effect were applied to solve the cut.

The silk / rayon sintered yarn can be preferably used for light use, the degree of twist is preferably 300 to 700 T / M, and the thickness is preferably about 140 to 150 d.

According to another embodiment of the present invention, a silk / rayon covering yarn covered with a silk yarn and a 21d × 3 fixing yarn is provided.

The covering yarn means a yarn wrapped around a core yarn with a covering yarn. In general, coverings are made to add other physical properties such as strength, elasticity, and touch to the examination.

The silk / rayon covering yarn can be preferably used for the above use, and preferably has a thickness of about 210 to 220 d.

According to another embodiment of the present invention, there are provided a sericin fixing step of fixing a first grade reagent under the conditions of a concentration of 5% owf, a temperature of 60 DEG C, a time of 60 minutes, a bath ratio of 1: 34, ≪ RTI ID = 0.0 > a < / RTI > reactive staining step of staining the silk / rayon yarn.

The present inventors initially tried to dye silk with an acid dye and dye the rayon with a reactive dye in two steps. However, in order to improve the fastness, sericin was fixed and the dyeing process was simplified by shortening the dyeing process by one bath to shorten the process. / Dyeing reliability was improved by using vinyl sulfonic dyes similar in cellulose conversion rate.

Hereinafter, the present invention will be described in more detail with reference to Examples. It will be apparent to those skilled in the art that these embodiments are merely illustrative of the present invention and that the scope of the present invention is not limited to these embodiments.

[Example 1]

The raw yarn 21dx2 and the rayon 75d were combined with general twisted yarn at 350T / M as shown in Table 1, and the twisted yarn 21dx3 yarn was produced as the covering yarn twisting yarn with rayon 120d.

[Example 1] Development of light-use combined speaker

In the initial phase of the 300T / M spinning process, a lot of truncation occurred, but tension was controlled by the adjustment of tension and flexing effect, and the combined story of 146d was developed.

[ Example  2] Above use Covering yarn  Development

The Rayon 120d twisted yarn was examined and covered with a 21d × 3 fixed yarn to develop a 216.4d covering yarn.

[Example 3] Development of fabric for silk sash / rayon combination yarn jacket

The slope is repeatedly arranged in two colors, each in a dark color and a color tone, and the company repeats the four colors in a dark color and a color tone respectively. As a graphic CAD system, the number of slopes was 5,760 (128 lines / inch). 4 patterns were developed as a simultaneous graphic design system. The patterns are shown in Table 2 below. Silk / Rayon yarn yarns were developed to weave 21dx2 yarns and rayon 75d yarns, weft yarns as 21dx3 yarn and rayon 120d, and the weaving machines were weaved using a Reiser G 6300 (Sulzer, Italy) loom.

[Example 4] Men's jacket fabric weaving

Silk / Rayon yarn yarns were developed to weave 21dx2 yarns and rayon 75d yarns, weft yarns as 21dx3 yarn and rayon 120d, and the weaving machines were weaved using a Reiser G 6300 (Sulzer, Italy) loom. Table 3 shows the pattern types of the developed fabrics. The developed fabrics were Sample No. 1 and No. 9, and the fabric patterns were made as ①, ②, ③, and ④, and the results are shown in FIG.

[Example 5] Development of an optimal dyeing process for silk / rayon blend yarn

The sericin fixing test was performed to improve dye fastness and shorten the process. Sericin 21 was used in two of silk 21 and three in 21. Sodium hydrosulfite, sodium bisulfite, and glutaraldehyde (GA) were used as the reagents used in the fixation. Sericin fixation by GA 5% owf, a temperature of 60 캜, a time of 60 minutes and a bath ratio of 1: 34, followed by washing with water. The sericin fixing process is shown in Fig. The results were the best at GA 5% and NaHSO ₃ 2%.

Next, the yarn was dyed with a reactive dyestuff in a cheese dyeing machine using 21 d / 2 mated fusing yarn and rayon 75 d, and the covered yarn 21 d / 3 mated fusing yarn and rayon 120 d combined yarn.

The amounts of trichloropyrimidine dyes are almost completely stained in silk and the vinyl sulfone dyes are slightly different depending on the type of dyes. . However, monochlorotriazine dyes are also slightly different depending on dyes. However, previous studies have shown that the cellulose part is slightly larger than silk, so in this study, vinyl sulfonic dyes having similar silk / cellulose conversion rates were used.

In the case of silk / rayon yarn, the color of the blue system was almost not dyed in rayon but only in silk yarn so that various reactive dyes were tested so that solid dye could be obtained. Reactive dyes were able to dye solid using Synozol Blue GN as an alternative to Levafix Blue E BRA dye.
