Description

Silk Blend Yarn {Silk Union Yarn}

The present invention relates to a fiber material in which the advantages of each fiber are mixed through blending and teaching with other natural fibers such as silk / cotton and silk / hemp to compensate for the disadvantages of silk.

Recently, the value of consumer is changing from the era of pursuing simple function or performance of product to the era of creating new value such as health, environment, and intellectual ability. There is a need for the emergence of materials with new values and functions that can cope with them, and the research and development to use materials in which various fibers are composited from a single material as a means to solve them is active in almost all industries including the textile industry. Is going on.

In particular, in the clothing industry, the core of product planning is shifting to efficiently reflecting and satisfying the complex and dynamic emotions of consumers by harmonizing materials and styles. It is no exaggeration to say that the choice of material determines the product's sales, since the overall quality is determined by interaction with other elements in the final product. Therefore, in order to accurately reflect the delicate emotional demands of consumers in product planning, an integrated study on factors that may affect the fashion material image is necessary.

These expectations have created a boom of well-being for consumers, and a variety of fibers based on high-performance eco-friendly materials are emerging one after another in the textile and fashion fields. In order to maximize comfort and naturalness, natural materials such as silk, cotton, and hemp are used, or plants such as bamboo and corn are spotlighted as eco-friendly fiber raw materials. Development of materials is actively underway.

Representative examples of natural fiber materials which humans have long used for clothing can be summarized as silk, cotton, hemp and wool.

Cotton fiber is a natural cellulose fiber made of cotton wool, which is not only used for clothing but also for underwear and bedding because it gives a comfortable feeling without absorbing skin and absorbs moisture well. It is strong in alkali and acid and resistant to friction, but has a disadvantage of poor wrinkle recovery.

Hemp fibers are extracted from the stems and bark of plants, such as mossina and burlap. Hemp fiber is inflexible because of its inflexibility, but it is used for high-grade summer clothes because it has a cool feeling due to its excellent absorption and breathability.

Silk, in particular, has been known as a queen of textiles for a long time because of its unique luster and touch. The development of silk-like materials that mimic the superior properties of silk is one of the main goals of the development of synthetic fibers. Among them, the development of high-performance fibers has emerged as a key concern in the global textile industry today.

However, silk is expensive, and the biggest obstacle to product diversification and consumption increase is the lack of practicality such as wrinkle resistance, abrasion resistance, shrinkage resistance, washing resistance, and poor dye fastness that should be used as clothing. It is working.

Therefore, in order to satisfy consumer's taste, a method of improving the defects of silk by forming crosslinks on the silk or blocking functional groups through chemical methods has been attempted.

The chemical improvement method shows the same effect as the improvement of defects on the surface, but since the excellent characteristic of silk is damaged, the physical improvement method is urgently needed.

In Korea, the technology for manufacturing mixed yarn that recycled selvage, which is a waste silk generated in the weaving process, has been completed. The technology for producing mixed yarns of up to 30'S depending on the blending ratio of silk, wool and acrylic through woolen spinning facilities Some domestic weaving companies are using cotton, hemp, rayon, and poly yarns for non-blended yarns, but specific data are not established, and products using silk / cotton and silk / hem blend yarns are developed. It is not happening.

The present invention aims to develop a fiber material in which the advantages of each fiber are mixed through blending and teaching with other natural fibers such as silk / cotton and silk / hem, in order to compensate for the disadvantages of silk.

The present invention relates to a blended yarn in which the yarn is silken and blended with SILK yarn, RAMIE yarn and / or COTTON yarn.

The blended yarn may comprise all of the silk, hemp, and cotton, and a blended yarn composed of silk and hemp (abbreviated as silk / hemp blend yarn) or a blended yarn of silk and cotton (if desired) Abbreviated as 'silk / cotton blend', and optionally other natural fibers such as wool yarn or the like may be mixed. In the case of silk / cotton blend yarns, it can be used as casual clothes by breaking the stereotype of silk, and thus the range of application becomes wider. In addition, silk / hemp blend yarn can be used as a summer clothing with a unique touch by adding a refreshing feeling unique to hemp fiber to the softness of the silk.

In one preferred example, the silk may be mixed in 30 to 70% by weight, wherein the blending amount of the hemp yarn may be 0 to 60% by weight, the mixing ratio of the cotton yarn is 0 to 50% by weight Can be. At this time, any one of cotton or hemp yarn is of course 1% by weight or more.

In addition, in some cases, the blended yarn may be spun mixed after 0-50% by weight of the wool yarn (WOOL), in a preferred embodiment, by adding about 20% by weight of the wool yarn to increase the cohesion of silk and hemp It can increase.

On the other hand, the blended yarn of silk and hemp may cause problems with the homogeneity in the three times 1/20 to 1/36'S of woolen yarn, such as 3/14, 1/15, 1/16, 1/20, 1/24'S, etc. desirable. Further, in one preferred embodiment, the blended yarn may be 50% by weight cotton, 30% by weight silk, 20% by weight wool, preferably for 3, 5, 7, 12, 14 gauge.

The present invention also provides a method for producing a blended yarn comprising a combination of silk yarn, hemp yarn and / or cotton yarn in consideration of the mixing ratio, and then carrying out spinning spinning.

The spun spinning is a method of spinning short fibers into slivers, and can maintain the shape of the fibers, unlike combing with combing. After spinning spinning, give a twist to the sliver coming out. The woolen spinning yarn generally comprises a combination process, a carding process, a square process, a winding process, and a twisted yarn / ply yarn process, and may optionally undergo a visa process.

The 'combination' process is a refueling and aging process as a pretreatment process for opening the compressed and packed raw materials by uniform mixing of raw materials and preventing trouble from occurring in subsequent processes.

The 'carding' process is a constant size to facilitate the square process by splitting the fiber web to make a thin film of the fiber produced through the equilibrium of the fiber to the uniform mixing of the raw material of the raw material and the various raw materials used to the desired constant thickness. It is a process of winding in the irradiation state.

The 'square' process increases the strength of the yarn by stretching the irradiation produced in the carding process to make the arrangement of the fibers more uniform to improve the uniformity of the yarn and to increase the coefficient of friction between the fibers by twisting the twisted slivers. It is a process of winding the bobbin in the unit of cob molding and a certain unit so that the produced yarn is opened in the winding process.

The 'winding thread' process eliminates the defects of the yarns produced in the carding and long process, for example, slub neb, microsemi, and placenta to improve the uniformity and appearance effect of the yarns, thereby reducing fabric defects after weaving afterwards. It is a process to package branches to enable continuous work.

The 'twisted yarn / plywood' process is used as a woolen yarn, which requires highly bactericidal system or thicker thread depending on the use. Joining process for the purpose.

In the 'steam setting' process, when there is a lot of soft water in a single yarn, snaling occurs and it causes thread trimming. Therefore, it is set to steam (about 95 ° C) to fix the twist to reduce the original recovery force of the fiber. To prevent snalling.

The problem with spun yarn spun yarn lies in the significant difference between dry strength and wet strength. In other words, fiber damage occurs during the spinning process due to a sharp drop in strength during drying, whereas high moisture strength in the case of excessive moisture content causes carding machine damage, increased adsorption, and winding of cardiac rollers. Is the point.

In this regard, the inventors of the present application performed the experiment of moisture change of the fiber in the woolen spinning process, whereby the water content at the time of initial lubrication reached almost equilibrium moisture with little change with the progress of the process at the end of the carding process. do. However, when the external force is applied or the temperature is high, the rapid moisture damping occurs to reach the equilibrium moisture, but it falls below the equilibrium moisture. On the contrary, when the external force or its temperature drops, the moisture absorption occurs to reach the equilibrium moisture. .

In consideration of this, according to one embodiment of the present invention, the hemp yarn is put in a plastic bag inside the sack, after the sack packaging is 25 to 50 ℃, preferably 30 to 100 ℃ 24 to 100 hours, preferably After 72 hours of aging, moisture and oil can sufficiently penetrate the hemp fiber. Accordingly, strong stiffness peculiar to hemp fiber can be reduced, moisture evaporation can be prevented, and flexibility can be improved.

In the carding process, it is desirable to produce the single yarn in the card and the square after adjusting the number of yarns by calculating the final number of elongation at 10%, and the number of twists is made by using the long-fiber characteristics of the yarn in TPM = K√Nm. K = 100 can be used for dragons and K = 50 for single use.

As a result of calculation of the number of spinning yarns of the hemp yarn, it was confirmed that the spinning yarns and hook fibers were generated when 111 N fiber yarns were 27 in case of 12 Nm. It was.

In consideration of this, it is preferable that the average fiber length of the yarn yarn is less than 3 ', and the bag number is more than 12 Nm. Thus, in one preferred example, the hemp yarn may be cut into an average fiber length of 2 1/2 ", the bag number may be 15Nm.

In addition, it is necessary to eliminate the poor spunness such as trimming due to the cutting of the hook fiber and the spalling due to the formation of the hook fiber as the equilibrium of the soybean fiber when spinning the long fiber. Therefore, proper bag number should be determined and preventive measures should be taken for spinning.

Since hemp fiber has a lot of broken fibers due to the reduction of moisture content in the spinning spinning process, it is necessary to provide a method of supplying water again. In this regard, according to the experiments performed by the inventors, the hardness increases due to the decrease in flexibility due to the lack of moisture, which causes a lot of trimming at the time of burning (in the case of RING spinning machine), and short fibers (derma) generated in the carding process. It was confirmed that much scattered. In consideration of this, it can be seen that even when the initial oil supply is excessive, water content is low at the end of carding to prevent lepping.

Therefore, in one preferred example, the lubrication rate of the combination of hemp yarns can be lubricated with water 28% to 30%, antistatic agent 0.5%, woolen 4% based on owf.

In some cases, in the preparation of the blended yarn, the yarn may be dyed first, and then combined with consideration of the mixing ratio, and then spun yarn. Unlike dyeing after yarn production, prior to raw material dyeing, it is necessary to make a database of the combination process to obtain a desired color. After all, if the desired color is determined in advance, the color of the final product is determined through the combination process in consideration of the mixing ratio.

Dyes can be used for dyeing silk and wool, and dyes for hemp and cotton can be used.

Examples of the acid dyes include C.I. Acid Yellow 17 introduced chlorine atoms in the coupling components to provide clear colors and improved light fastness, and C.I. Acid Yellow Red 131 introduced a hydrophobic group to improve wet dryness, and C.I. Acid Green 27 is a milling acid dye.

As an example of the reactive dye, C.I. Reactive Yellow 2 has a good daylight fastness and is a red pigment mother dye, C.I. Reactive Red 17 has a high molecular absorption coefficient and strong light and chlorine resistance. C.I. which is an anthraquinone-based reactive dye which is a dyestuff of blue reactive dye. Reactive Blue 19 has clear color and good light fastness but lower molecular absorption coefficient than metal complex type.

In addition, natural dyeing is also possible, for example, the pigment component of cochinyl dye, a natural dye, is an animal dye, the English name is Cochineal, the scientific name is Coccus Cacti L., and the main ingredient is carminic acid, and the hydroxyl value (-OH) and acetic acid group. It has a chemical structure with (-COOH). Pigments are sensitive to pH and cause halochromism (colorlessness) by adding large amounts of dark acid and metal salts to colorless, pale yellow organic compounds. Easily soluble in water, alcohols and ethers, insoluble in benzene and chloroform.

Dyeing process can vary depending on the type of yarn, silk and wool can be dyed under the same dyeing conditions as in Figure 1 with an acid dye concentration of 0.01 ~ 1.4% (o.w.f) using a carrier dyeing machine.

In addition, cotton and hemp can be dyed under a field dyeing condition as shown in Figure 2 RIFA Fixf dye concentration 0.02 ~ 5.3% (o.w.f) using a carrier dyeing machine.

In the case of natural dyeing, the dye may be extracted first, and then dyeing may be performed by immersing the pre-embedded sample in a dye through a embedding process. The mordant for natural dyeing may include aluminum potassium sulfate (AlK (SO ₄ ) ₂ 12H ₂ O), forget-me-not (Na ₂ SO ₄ ) and soda ash (Na ₂ CO ₃ ), but is not limited thereto.

The present invention also provides a woven or knitted fabric woven using the blended yarn.

It is a dye-dyed silk blend yarn that uses jacquard looms to produce fabrics and knitted fabrics of various patterns. It is possible to produce spring and autumn products in woolen spinning, which mainly produces winter products.

In addition, when dyeing silk and wool, which are animal fibers having different dyeing properties, is mixed with hemp and cotton, which are vegetable fibers, yarns and melanges of various colors can be given through a combination process using pre-dyed raw materials.

In the teaching fabrics and knitted fabrics prepared according to the present invention, the daylight fastness was excellent in grade 3, wash fastness 4 or more, the tensile strength was high at least 20 kgf or more. Fineness can be produced in about 16Nm in consideration of bagability and commerciality, and can be used in combination of two to produce a blend yarn of 20Nm or more. Shrinkage was excellent within 3% of the fabric, but in the case of knitting, it is necessary to adjust the structure, density, etc. to compensate for the shape stability.

It is preferable to use a top saw that is not cut for hempness. In the case of 1/36'S, which is finer yarn, both silk and hemp have no crimp, so the twisting occurs in the knitting yarn due to the lack of cohesion of the fiber.

As a result of using silk and hemp slivers, it was about 6 cm, and the fine characteristics of the silk ensured that each roller gauge could be checked to prevent the winding of each roller.

In other words, since knitting yarns are not as elongated as conventional wool yarns, they can be produced by increasing the mule year by 15-20%, but without twisting the sweater. In addition, in the case of weaving yarn, since the yarn is not as elongated as the existing yarn, the twisting phenomenon occurs after the mule is produced, so the mule year should be reduced by 15-20% to be produced, but it should be avoided from falling out of the loom.

Appropriate lubrication data can be established by examining the combination and lubrication of silk and hemp in the combination process. In the spinning process, you can check the drape of silk and hemp in checking the hair loss condition and determining the card number.

In case of silk and hemp, it is preferable to proceed dyeing after pretreatment if softener treatment is required.

Once the silk / cotton and silk / hem blend conditions are established, it is difficult to wear and store, and it can be revived to the expectations of consumers by developing fabrics that have increased practicality by avoiding the stereotypes of silk that were previously recognized and used as high-end clothing. Production of the product is possible.

It is expected that the blending of natural fibers will lead to the development of products with added functionality, which will lead to an increase in demand. In addition, it can be used as a summer clothing with a unique touch by adding a refreshing feel unique to hemp fiber to silk softness.

Advantages and features of the present invention and methods of performing the same will be understood more readily by reference to the following detailed description of the embodiments and the accompanying drawings.

I. Washing fastness: Washing fastness was measured by KS K 0430 A-1 method.

Dyeing Fastness Evaluation Results

 [Table 4]

Table 4 shows the daylight and washing fastnesses of the fabric and knitted fabric using silk blend yarn as the weft yarn, and showed the highest fastness of grade 3 or higher in the daylight, which is the most disadvantage of silk. In addition, the wash fastness also showed excellent fastness to more than 4-5 grades. As a result, it was found that by using the fibers of the other disadvantages of the silk, it is possible to obtain the effect of improving the fastness and the physical properties.

Experimental Example 4 Evaluation of Mechanical Properties

Mechanism Evaluation Method

end. Tensile Elongation: Tensile strength was measured using a tensile strength tester (Shimadzu, AGS-500A, Japan) at a tensile rate of 100 mm / min by the KS K 0520 Revelled Strip method.

I. Shrinkage: Shrinkage was measured by KS K 0603 soap solution method.

All. Bending characteristics: Bending characteristics were measured in the warp and weft directions using the KES-FB2 System (Kato Tech., Japan).

la. Spindle degree: The spindle degree was measured by tilting and weft direction by KS K 0550 open angle method and expressed as wrinkle recovery angle (WRA).

Evaluation result of mechanical characteristics

Figure 7 shows the tensile strength of the fabric using the silk blended yarn spun as weft in the conditions as shown in Table 1, it can be seen that the impact on the number of yarns and the number of twists and mixing. The strengths were all greater than 20 kgf, especially in the case of A having a high mixing ratio of silk and a high number of twists.

Figure 8 shows the tensile strength of the fabric using the silk blended yarn spun as the weft yarn in the conditions as shown in Table 1, it can be seen that the impact on the number of yarns and the number of twists and mixing.

Figure 9 shows the shrinkage rate of the woven fabric and knitted fabrics with silk blend yarns, the lack of structural stability in the knitted fabrics are reduced in the direction of the wale while the opposite direction in the coarse direction needs to be improved by adjusting the texture and density. I think it is.

In the case of the fabric, silk yarn was used in the inclined direction, but the shrinkage was less than 5%. In the weft direction, the silk blended yarn was used to show the excellent shrinkage of less than 2%.

Table 5 below shows the relationship with the bending stiffness B. Since the value of B indicates that more power is required to bend, both silk and cotton show flexibility in processing conditions. It can be seen that it becomes more flexible.

The bending hysteresis width 2HB, which shows the elastic properties of bending behavior, is the difference in energy due to bending and restoration. Accordingly, the smaller the 2HB value, the lower the energy loss due to the restoration, and the smaller the deformation of the processed fabric, which indicates that the shape stability of the fabric is greater. Among the silk blend yarns, the 2HB value of the knitted fabric using H yarn was the smallest, and the shape stability was the best.

Table 5 Bending rigidity and bending hysteresis of sample fabrics.

On the other hand, since the fabric was used as the weft yarn of Taeseomdo, the bending characteristics could not be measured and the degree of spindle stability was measured to compare the shape stability of the fabric. Spinal cord represents the resilience to external force. The larger the value, the better the shape stability.

Table 6 shows the spindle degree of the fabric. The same silk silk yarn showed the same value, but showed the best morphological stability in the fabric using G (50 wt% silk and 50 wt% wool) among the silk blend yarns.
