1 and 2 illustrate a process for producing a natural composite yarn according to an embodiment of the present invention.
Figures 3-5 illustrate a knitting design in accordance with an embodiment of the present invention.

Hereinafter, the present invention will be described in more detail.

Recently, well-being and eco-friendly fashion have attracted a great deal of consumers' preference for natural sensitive materials that have superior sensibility and natural functionality than conventional synthetic fibers. Modal and tencel, which are vegetable regenerated fibers produced from pulp, can be used to meet the needs of such consumers. However, when natural fibers are used as warp yarns as warp yarns, there are limits to the regular warp process such as warp, And it is difficult to use as a material for warp knitting.

Therefore, it is necessary to develop a natural complex differentiation material based on warp knitting. In view of the above circumstances, the present invention provides a natural composite yarn suitable for the warp knitting process, and provides a knitted fabric capable of satisfying consumer's sensibility needs by providing a cannon using the provided yarn and a knitting technique.

The natural composite spinning yarn suitable for the warp knitted fabric according to the present invention is obtained by kneading a natural fiber of Tencel or Modal and a polyester fiber of 0.7 to 2.0 denier in a weight ratio of 15:85 to 70:30, Preferably, the yarn yarn is a twisted yarn of 3.2 to 4.5 T / M as a mixed fiber of the natural fiber and polyester yarn using a time-compact device, a yarn having a twist of 20 to 1/80's / And may be a narrow-space spun yarn.

According to the present invention, the yarn yarn produced using the above-described interlaboratory compacting device is produced by simultaneously feeding two irradiating yarns (1, 2) to the irradiation interval guide (3) And the elongated two strands of the yarn are stretched by the back rollers 4 to the front rollers 8 which are the draft regions of the yarn squares and are fed to the front roller 6 and the feed roller 8, Compact yarn passing through the bundling mechanism 7 to tighten the irradiations 1 and 2 and then passing through the balloon prevention ring 9 and twisting through the ring traveler 10, Feature.

The natural composite yarn according to the present invention preferably has a coefficient of variation of 1.0 to 2.0 CV%, a yarn strength of 15 to 25 cN / tex, an elongation of 7 to 16%, a uniformity of 9.0 to 12.0 U%, a mowing index of 2.5 to 5.0 cm It is preferable to manufacture it so as to have physical properties.

If the physical properties are not satisfied, not only the efficiency of the mirror can be reduced but also the quality of the warp yarn may be affected. More specifically, when the coefficient of variation of the coefficient of variation is less than 1.0 CV%, there is a problem in that the feeling of naturalness on the fabric falls. When the coefficient of variation is more than 2.0 CV%, a barley phenomenon may occur in the appearance of band- If the quadratic strength is less than 15 cN / tex, there is a problem in that the pinhole is flawed due to truncation or light knitting in the cannon. In case of exceeding 25 cN / tex, If the elongation is less than 7%, there may be a problem that the cannon thread trimming occurs too much and the fixing efficiency decreases. If the elongation exceeds 16%, there is a problem that the workability of the warp thread is poor due to high elongation .

If the uniformity is less than 9.0 U%, there is a disadvantage that the natural feeling of fabric is lowered. If the uniformity is more than 12 U%, there may be a disadvantage that the appearance of the warp yarn is dirty. If it is more than 5.0 cm, there is a disadvantage that Nep is defective in the warp knitted fabric due to the gathering of moths during the regular work, and some moths are scattered and scattered and the working environment is lowered.

Another object of the present invention is to provide a method for producing the natural composite yarn, which is suitable for weaving knitted fabrics, and more particularly, to a method for manufacturing a natural composite yarn, It is an object of the present invention to provide a method for producing a spun yarn.

A method for manufacturing the above-described narrow-width yarn according to the present invention will be described in more detail with reference to FIG. 1 or FIG. 2,

Tencel or Modal natural fibers and 0.7 to 2.0 denier polyester fibers are prepared and blended with the natural fibers and polyester fibers to prepare a blend sliver, And then the sliver is supplied to the coagulant to produce irradiations (1, 2) having a weight of 120 to 200 gr / 30 yds, and then the irradiated two strands are simultaneously irradiated through one irradiation area guide (3) And the elongated irradiation passes through the air suction type focusing mechanism 7 located between the front roller 6 and the delivery roller 8 to make the fibers densely and then passes through the ring traveler 10 The twist number 3.2 to 4.5T / M is characterized by producing twist yarns.

At this time, it is preferable to feed the densely fabricated fibers through the balloon prevention ring 9 in order to prevent the balloon before it is supplied to the ring traveler 10.

The thus prepared yarn is wound and prepared in a cone shape (11).

According to the present invention, the silo-compact yarn is configured such that any one of natural fibers of Tencel or Modal and polyester fibers of 0.7 to 2.0 denier have a weight ratio of 20:80 to 70:30 . If the weight ratio of the natural fiber to the polyester fiber is out of the range, the tensile strength and tearing strength of the warp yarn are too low, or hygroscopicity and comfort are poor.

According to another aspect of the present invention, there is provided a yarn-compact yarn according to another aspect of the present invention, wherein the yarn-compact yarn is made of any one of Tencel or Modal natural fibers and 0.7 to 2.0 denier polyester fibers at a weight ratio of 20:80 to 70:30 And a composite spinning yarn can be produced at a spin rate of 12,000 to 19,000 rpm by applying a twist in the Z direction at 3.2 to 4.5 T / M.

According to the present invention, the soft-softening process preferably has a number of doubling strands of 6 to 8, a sliver weight of 200 to 300 gr / 6yds, a drafting load of 10 to 40 kgf, an R / O gauge of 47 to 52 mm, 1.3. ≪ / RTI >

If the number of doubling strands is less than 6, the homogeneity is lowered. If the number of doubling strands is more than 8, the stretching ratio in a draft region is high, so that the number of strands may become uneven.

In addition, when the Sliver Weight is less than 200 gr / 6yds, the productivity is decreased and the cost is increased. When the Sliver Weight is more than 300gr / 6yds, the posterior process causes the thickness of the irradiation to be uneven.

In addition, when the drafting load is less than 10 kgf, there is a disadvantage in that the uniformity is lowered, and when the drafting load is more than 40 kgf, there is a disadvantage that the abrading degree of the drafting roller is increased.

Also, when the R / O gauge is less than 47 mm, there is a disadvantage in that the uniformity is lowered due to the high force received by the fibers. When the R / O gauge is more than 52 mm,

If the Break Draft is less than 1.2, the preliminary elongation is hardly received and the homogeneity is reduced due to the action of the main draft. If the break draft is more than 1.3, the main draft is relatively lowered, There are disadvantages.

It is another object of the present invention to provide a method for preparing a warp yarn using any one of the natural composite yarns of the present invention. The yarn preparation method, the canopy process, the transparency process, (Looming) process,

The regularizing process was performed by arranging the warp yarns in parallel and setting the tension constant to 58 gauge 28 gauge knitting machines. 32 gauge knitting machine 672 It is the most important process to determine the quality of knitting by winding the yarn. In the regularity process, the yarn surface and the contamination are inspected on the basis of the first-in first-out yarn, and the irregularities and the abnormal portions are checked on the apostrophe, the discharge is cleaned and the static electricity is prevented, It is desirable to maintain the working environment at a temperature of 26 to 30 DEG C and a humidity of 60 to 70% in order to maintain the friction coefficient of the yarn.

In addition, in the regularizing process, it is preferable to change the tension according to the thickness of the yarn using the tension regulating device KFD, and to set the tension to 17-18G on the basis of the number of tencels 40. At this time, since the tension of the yarn is increased as the yarn is thicker, the tension of the tension must be increased, and the tension of the yarn is sensitive to the surrounding environment.

As described above, the natural composite spinning yarn provided by the present invention is a spinning yarn suitable for a warp knitting process using a sensitive woven material differentiated from conventional synthetic fibers, and by using the knitted fabric established in the present invention, . In particular, it can provide a 2-way tricot tricot product for premium fashion outdoors that can meet consumer needs.
