Description

Blended yarn and its manufacturing method and its one-bath dyeing method {BLENDED YARN AND PREPARATION THEREOF AND ONE-BATH DYEING}

1 is a manufacturing process of the blended yarn according to an embodiment of the present invention.

Figure 2 is a dyeing process of the blended yarn according to an embodiment of the present invention.

The present invention relates to a blended yarn, a method of manufacturing the same, and a dyeing method of the bath, and in particular, a blended yarn and a method of manufacturing the same and a component thereof, which can express the advantages of both fibers by blending silk and bamboo fibers. It relates to a one-bath dyeing method for the fiber.

Silk fiber is a material that is easy to dye due to its excellent adsorptive power when it has warmer and elegant characteristics among natural fibers, but it has a high recoloring rate, poor fastness and difficult processing. On the other hand, bamboo fiber is known as a natural fiber that is good for humans and the environment, and is considered as an optimal fiber that can replace rayon materials in terms of resources, production process, production cost and biodegradability. Recently, related products using bamboo fiber have been developed and marketed one after another. Because bamboo fiber is somewhat lower than general fiber material in terms of physical properties, there is a growing need for complexation of synthetic fiber or other natural fibers or blending, rather than single material.

In view of this, Korean Patent Invention No. 467226 uses a cotton yarn as a local yarn, a mixed yarn of bamboo and cotton fibers as a weft yarn, and a weaving yarn using a mixed yarn of polyester and cotton yarn as a top yarn. The manufacturing method of the functional towel which was woven so that the surface which has a good water absorption effect by heat processing and the durable polyester is located in the inner layer was proposed. Although this suggests a mixed yarn of cotton and bamboo fibers, it is different from the present invention in that it is a mixture of cellulose fibers having strong surface friction characteristics.

Meanwhile, Korean Utility Model Model No. 36307 uses bamboo yarns made of lecture yarns of 1000 to 3000 T / M, and silk yarn surrounds the bamboo screening as an external yarn. A bamboo-silk composite yarn composed of a mixture of 5 to 80% by weight as a standard was proposed.

The composite yarn has a disadvantage in that it is difficult to be used in high-quality paper such as suiting in that there is a limitation in the number of production composite yarn or the method of manufacturing as a core yarn to improve the difficulty of spinning due to the surface characteristics of silk yarn.

In order to solve the above problems, an object of the present invention is to provide a blended yarn and a method for manufacturing the same that can complement the disadvantages while sharing the advantages of the silk fibers and bamboo fibers.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that in the drawings, the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

As used herein, the term "fabric" is used to include all articles, nonwoven fabrics and fibrous webs produced by weaving or knitting.

1 is a manufacturing process diagram of the blended yarn according to an embodiment of the present invention.

The blended yarn according to the present invention is a blended yarn mixed with silk fibers and bamboo fibers. Silk fiber is a material that is easy to dye due to its excellent adsorptive power when it has warm and elegant properties, but it has a high recoloration rate, poor fastness and difficult processing. Meanwhile, the bamboo fiber may be manufactured using a rayon method after processing into a bamboo pulp as a cellulose fiber. Bamboo fiber itself has a permanent cooling, antibacterial, deodorant and excellent UV protection and anion generation function, gives a refreshing texture due to the excellent breathability and light weight of the hollow structure, and has a soft touch and easy to dye.

Therefore, the blend of the two fibers will be said to be a very excellent combination that can complement each other while maximizing the advantages of each other in terms of reprinting or processing.

The silk fiber has a disadvantage that the surface friction coefficient is not suitable for spinning. Therefore, the silk fiber used in the blended yarn according to the embodiment of the present invention is subjected to the pretreatment of the silk fiber prepared in the form of a staple by cutting into a length suitable for crimping and spinning. Crimped silk fibers have improved surface friction properties and improved spinning properties.

Meanwhile, bamboo fibers are also cut to a certain length in accordance with the final number of times and supplied in staple form (bamboo fiber pretreatment step).

Each of the pretreated fibers is mixed in a blending process (mixing step). In this case, the blending ratio is preferably 50% by weight of bamboo fiber 50 / dog fiber to 10% by weight of bamboo fiber 90 / dog fiber. In the case of more than 50% by weight of the silk fiber, the loss rate of the silk fiber increases during the spinning process, which is a problem in productivity. In the case of less than 10% by weight of the silk fiber, the blending ratio of the silk fiber is low, so that the blending effect is very low. This is preferable.

The blended silk and bamboo fibers may be randomly distributed on the fiber cross section through the blending cotton.

The mixed fibers that pass through the blender are maintained in a lap form and formed into slivers through a carding step. In the carding step, the fibers can be arranged uniformly in the longitudinal direction of the yarn and remove dust or contaminants that may be included in the fibers.

The blended slivers that have undergone the carding step are combined into six to eight pieces and then reformed into one sliver through a draft (softening step). In a typical spinning process, after a carding step, a regular carding step is performed, but since both fibers are arranged in the longitudinal direction and combing is performed to a certain extent in the process of stapling, both of the fibers of the present invention In the method of producing a blended yarn it can be omitted.

The sliver having undergone the softening step optionally forms an irradiation with a certain thickness through an additional draft (prescription step). The spinning step may be omitted in the case where the number of times necessary for the number of the final yarn is large or the number is small.

The sliver having undergone the softening or roughening is subjected to a square step so as to match the final number and the number of twists. The square method may be formed by a ring square or a rotor square. After the spinning step, the blended yarn is wound on the bobbin so as to meet a predetermined weight while eliminating defects (thick, thin, weak, etc.).

Next, a method of dyeing the blended yarn will be described.

Blended yarn made of bamboo fiber and silk fiber has two components, and there are many things to consider when dyeing after weaving. First of all, bamboo fiber is a cellulose-based fiber, and silk fiber is difficult to select a suitable dye due to structural differences in terminal groups in terms of protein fiber. In addition, due to the difference in physical properties of each of these fibers, a dyeing method that can meet certain requirements such as daylight fastness should be studied. In particular, it is necessary to consider that the silk fibers do not differ from the dyeing properties of the bamboo fibers without impairing the gloss characteristic of the silk fibers. Furthermore, in terms of productivity, a dyeing method that can be realized in one bath is required.

In this respect, the present inventors propose the following method.

The blended yarn is used to weave or knit the fabric.

In the blended yarn, the bamboo fiber may be refined or mercerized by a pretreatment step in terms of cellulose-based fiber. Refining may be a means for improving dyeability by removing secondary impurities that may occur during blending or weaving. Meanwhile, prior to mercerizing, dyeing may be improved as the glossiness of the bamboo fiber is enhanced and the strength is increased.

The refining process uses a one bath refining method and may be performed at 70 to 90 ° C. for 10 to 15 minutes. The refining effect may be reduced when the refining step is performed at less than the temperature and time, and the physical properties (particularly, silk fibers) of the fiber may be reduced when the refining step is exceeded.

In the case of dyeing the blended yarn according to the present invention, since it is intended to dye the cellulose fibers and the protein fibers in one bath, it is preferable to use a reactive dye in which both fibers can be formed. Direct dyes may be used in dyeing cellulose fibers, but are not suitable for silk fibers and may be low in color fastness. It is known that acid dyes are not suitable for cellulose fibers. The basic dye is suitable for silk fibers, but there is a problem in that the dye is not richly dyed to cellulose fibers unless an acidic mordant is used. The mordant dye is not suitable because it has a problem of inhibiting the glossiness of the silk fiber is pre-treated with a metal salt in advance to fix the fiber. Bat dyes and azoic dyes are also undesirable because they are particularly suitable for cellulose fibers. After all, the reactive dye has an active reactive group capable of reacting with an amino group or a hydroxyl group in the dye molecule, and since it reacts with the amino group or the hydroxyl group of the fiber to form a covalent bond, it is most preferable for dyeing the blend of bamboo fiber and silk fiber according to the present invention. Judging. In addition, as a dyeing aid, a leveling agent, a chelating agent, or the like may be used. For example, sodium sulfate (Na ₂ SO ₂ ) may be used. Alkaline binders (particularly liquids) may be used as the leveling agent, which is believed to increase the dye fixation rate on each fiber. The dye treatment is preferably made for 40 to 60 minutes at 60 to 100 ℃. In addition, the amount of dye used may vary depending on the tone of the color to be produced. Preferably, it is 0.1000 to 5% (owf), but below or exceeding the above standard, predesigned color implementation is difficult and may result in low fastness.

Fabrics subjected to the dyeing step are subjected to a neutralization step, which can improve the glossiness of the silk as a humectant, for example, acetic acid. (Acid Brighting)

Afterwards, the dyeing can be completed by post-treatment as a shopping agent.
