Description

TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a high-esthetic air jet texturing yarn, and a method of manufacturing a high-esthetic air jet texturing yarn,

The present invention relates to an air jet texturing yarn which is produced by making an air jet texturing yarn optimized for the warp or weft of a velvet fabric structure by changing the air nozzle structure of an air jet texturing yarn manufacturing apparatus, And to provide a velvet fabric using the texturing yarn. BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a method of manufacturing a high-esthetic air jet texturing yarn,

Velvet fabrics are woven fabrics with a certain length of pile in weft or warp constituting the ground weave and are widely used for upholstery, seat cover, sewing toys in addition to dresses, coats, hats and shawls .

Generally, the production of velvet fabric is made by alternately weaving the pile fabric and the pile fabric, cutting it into a cut pile after the weaving, and making the annular loop appear to be densely appearing on the surface Or by the intersection of warp and weft, the pile yarn is made to reciprocate to the upper and lower side tissues in the process of weaving with the double yarns of the upper and lower side tissues to form the pile structure and cut the middle part of the pile structure to be two pile fabrics Thereby causing the cut file organization to become a file and appear on the surface of the fabric.

The velvet fabric gives a directionality to the pile to give a slight luster, and the light and shade are expressed by the difference of the light reflectance of the end and the side of the pile, and the pile and the beauty are provided to manifest the abundant surface effect, In addition, various patterns can be imparted to the surface depending on the length of the pile and the method of weaving, and the pile has been treated as a high-grade fabric.

However, the conventional structure of the velvet fabric is made of nylon for the stable shape of the fabric itself and the polyester yarn as the weft for emphasizing the esthetics. However, since the manufacturing cost of the polyester yarn is high, It is required to develop a relatively low-cost alternative material while maintaining the characteristics.

In addition, a file characteristic of a velvet fabric is difficult to keep in a certain direction because the form is easily collapsed when an external force is applied. If the external force is repeatedly applied, the file can not be returned to its original shape even after the external force is removed, There is a problem.

In addition, when the number of files is increased to increase the surface density so that the paper texture of the velvet fabric is not exposed to the outside, the soft touch of the pile yarn is reduced. When the file length is increased while the number of the pile file is decreased, And the upright shape is easily collapsed by an external force.

Especially, when embossing with a velvet fabric or wrapping an edge or the like, the pile is split in both directions around the angled portion, and the paper tissue at the angled portion is exposed to the outside, thereby deteriorating the beautiful appearance of the velvet fabric.

In order to solve the above problems, Korean Patent Laid-Open Publication No. 2011-0008210, Korean Patent Publication No. 1508847 and Korean Patent Publication No. 1611012 disclose a honeycomb structure having cross- There has been proposed a method of producing a yarn for a velvet fabric having a flat, M-shaped, and triangular cross-section by discharging a molten polymer using a spinneret having a discharge hole having a straight shape, an M shape and a triangular shape, The velvet fabric is produced, the pile-up phenomenon of the file is reduced, the softness is improved due to the bulky characteristics, and the effect of producing the soft and strong gloss is provided.

However, even if the cross-sectional shape of the yarn for the velvet fabric is changed, it is difficult to expect changes in the physical properties such as the strength and elongation of the yarn, so that even if the velvet fabric is made using the same, the morphology stability is similar to the conventional one, , The exposed tissue will detract from the overall appearance of the velvet fabric due to the apparent difference in appearance to the pile tissue.

Korean Patent Registration No. 0919467 discloses a nylon air texturing yarn as a warp yarn, a core yarn of polytrimethylene terephthalate multifilament as a weft yarn, a nylon multifilament yarn and a polyethylene terephthalate multifilament yarn and a polytrimethylene terephthalate multifilament yarn A method of weaving a denim synthetic fiber fabric using a composite air texturing yarn in which an effect yarn made up of a selected one type of multifilament is air-textured has been proposed. The fabric using such an air texturing yarn has excellent stretchability in the direction of weft, , Dry feeling and good volume feeling, and synthetic fiber was used, but it provides a touch and appearance similar to that of a woven fabric using a natural fiber spun yarn.

When the fabric is applied to the fabric of the velvet fabric, even if the fabric is exposed to the outside, the appearance of the fabric can be prevented to some extent due to the characteristics of the air texturing fabric constituting the fabric. However, Since the air-texturing process has a lower strength than that of the yarn and the air-texturing yarn has a large elasticity, the shape stability of the fabric for the fabric is low, so that the standing of the file easily collapses due to the use of the velvet fabric, There is a problem of damage.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a velvet fabric which can prevent appearance damage caused by exposure of the fabric structure to the outside without increasing the number of files of the velvet fabric, And to provide a method of manufacturing an air jet texturing yarn optimized for warp yarns or weft yarns.

In order to solve the above-described problems, the present invention provides a method for supplying air to an air nozzle (B) of an air texturing apparatus while supplying a material yarn to an air supply port (B-1) (B-1) composed of a plurality of air nozzles (B-1) is arranged on the outer circumferential surface of the air nozzle (B) 2 are disposed at different positions on the material yarn passage B-2 at an angle of 25 to 35 degrees with the material yarn passage B-2, or a part of the air supply port B-1 is disposed at the same position, The air pressure to be supplied to the air supply port B-1 is 7 to 9 bar and the speed ratio between the supply speed of the yarn before and after the air nozzle B and the discharge speed Speed) / discharge rate x 100) is 15 to 25%, and the number of yarns before and after the heater The speed ratio between ((discharge speed - feed rate) / feed rate × 100) between the feed rate and feed rate is 4.0 to 5.5%. (Rate of withdrawal speed-discharge rate of the downstream end of the heater / discharge rate of the downstream end of the heater × 100) between the above-mentioned winding speed and the discharge rate of the rear end of the heater (D) is 9 to 10% Wherein the roller for supplying and discharging the yarn is surface-roughened in the form of an orange ball.

The present invention also provides a velvet fabric using an air jet texturing yarn produced by the above method as a warp or weft of fabric constituting the fabric of the velvet fabric.

At this time, the warp or weft yarn is nylon yarn or polyester yarn having a fineness of 70 denier or more and a strength of 3 gf / d (load / denier) or more and a filament yarn fixed to the weave pattern has a fineness of 75 to 200 denier and a yarn count of less than 3 gf / Of acetate.

It is also preferred that the velvet fabric is woven selectively connected to the cam-type sheathed drive device and the dovetail sheathed drive device.

The air jet texturing yarns produced by the method of the present invention are characterized in that the loops are randomly formed at a low height from the center of the yarn so that they are less stretchable compared to conventional air jet texturing yarns, So as to give a smooth surface feel.

In addition, by woven the ground structure of the velvet fabric with such an air jet texturing yarn, it is possible to impart to the ground structure of the velvet fabric the improved baldness of the air jet texturing yarn, the expansion and contraction characteristics by the loops and the shape stability, By keeping the file organization stable, the paper organization is not easily exposed to the outside, and even when some of the paper organization is exposed, the air jet texturing company's bulkiness and luxurious gloss characteristics can maintain the beautiful appearance of the velvet fabric.

The present invention proposes a method of producing a high-esthetic air-textured yarn (ATY), which has the unique cold feeling of conventional synthetic fibers and the problem of reduced excessive surface gloss and handle, The present invention relates to a technique for weaving an air jet texturing yarn produced by a method into a fabric of a velvet fabric.

In order to manifest the bulky characteristic in the processing of the yarn, a false-twisting method in which the yarn is twisted and twisted is used, or a method in which two yarns are entangled with high-pressure air to induce an artificial surface change However, in the present invention, it is necessary to separate from the false twisting process or the air texturing process, which is a conventional yarn processing process, to pass through a specialized air entraining nozzle using a single material to form a natural loop, To produce an air jet texturing yarn.

Further, by applying the conventional air-jet texturing yarn fabric of the present invention as an alternative to the conventional fabric of the velvet fabric, it is possible to reduce the feather feeling (volume feeling) due to cold feeling and tension, which is a disadvantage of synthetic fibers, It is possible to compensate for the lack of stability and to stabilize the structure of the paper tissue uniformly and stably, and weaving the paper tissue and the file structure by selectively connecting the cam type sheave drive apparatus and the dovetail type sheave drive apparatus, To make a velvet fabric.

A conventional air jet texturing yarn (ATY), as shown in FIG. 1, generally comprises two types of yarns separated into a core yarn yarn and an effect yarn to form an air nozzle, And then passing it through the process.

The method of manufacturing an air jet texturing yarn of the present invention has the same thread guide as that of a conventional air texturing process, but using a specially designed air nozzle without using a wetting device, The produced air jet texturing yarn has a soft touch feeling by a specialized nozzle and forms a density feeling of a pile when it is used in a pile fabric of a velvet fabric and plays an important role in determining the uprightness and the high gloss characteristics.

Fig. 2 shows a detailed structure of a conventional air nozzle A used in the process of manufacturing an air jet texturing yarn and an air nozzle B specially designed according to the present invention.

As shown in Fig. 2, air nozzles A-1 and B-1 are arranged at an angle of 120 degrees with respect to the air nozzle 3, and are supplied to the material passing through the center of the air nozzle. The supply port A-1 concentrates supply of air to one point of the material yarn passage A-2 while forming an angle of 45 ° with the material yarn path A-2, (B-1) are arranged at different positions on the material yarn passage (B-2), or two air supply ports (B-1) The air supply port B-1 at a certain position is disposed at one point on the material yarn passage B-2, and the remaining air supply port B-1 is disposed at another position.

To be more specific, the conventional air supply port A-1 is located at a distance of about 9 mm on the basis of the tip of the discharge port on the material thread passage A-2 of the air nozzle A, One of the air supply ports B-1 is spaced apart from the tip of the discharge port by 12 to 16 mm, and the remaining two positions are spaced by 7 to 11 mm similar to the conventional one, so that one of the air supply ports B- It can be disposed closer to the entrance of the air nozzle (A) than the remaining two.

Although the air supply port B-1 of the present invention has been described in the above, three or more air supply ports B-1 may be provided. Alternatively, four or more air supply ports B- 1 may be disposed at different positions on the material yarn passage B-2, or some of the air supply ports B-1 may be disposed at the same position and others may be disposed at different positions.

As described above, the air supply angle of the air supply port B-1 is made smaller than that of the conventional air supply port B-1, thereby lowering the resistance force of the air supplied to the material yarn in the air nozzle B, (B-1) of the air supply port (B-1) of the present invention, the entire filament constituting the material is naturally disturbed.

In detail, the material prepared on a creel is unwound and supplied to the material thread passage (B-2) of the air texturing apparatus. At this time, the speed of the material yarn supplied to the air nozzle of the air texturing apparatus is controlled at a rate And a loop is formed in the workpiece that has passed through the air nozzle by the overfeeding and the turbulent effect of the air current supplied from the air supply port B-1 of the air nozzle.

 At this time, the filament shape of the material yarn is changed according to the air supply angle of the air supply port (B-1), and in order to realize a shape in which the filament made of one material is naturally disturbed, And position changes are essential.

That is, in the air texturing mechanism, the lengths of the straight sections of the material yarn passages A-2 and B-2, the positions of the air supply ports A-1 and B- -1), the shape of the loop of the air jet texturing yarn manufactured according to the angle change of the air nozzle (A, B) outlet section of the tapered airflow tube like a fallopian tube (sudden expansion or gentle gradual expansion) In the conventional air nozzle A, the air supply port A-1 is disposed at the same position, so that the loop shape is large and strong. In the present invention, the angle and position of the air supply port B- And the elasticity recovery rate is increased. The elasticity recovery rate is increased by using the upper slope of the fabric of the velvet fabric to provide the effect of tightening the dough tissue tightly. Thus, Even if it is composed of the same number and density as water, the shape stability is ensured.

In the air texturing apparatus, high pressure air has an effect of twisting the filament shape of the material yarn. The air pressure supplied to the air nozzle (A) of the conventional air jet texturing yarn manufacturing apparatus varies depending on the fineness of the material yarn. The air nozzle B having a special design as in the present invention is required to supply low-pressure air, and air having an air pressure of 7 to 9 bar.g is supplied to the air supply port B- 1).

Since each of the filaments of the material yarn independently and naturally forms an inflated shape by forming a loop with air having a low pressure as described above, the air jet texturing yarn manufactured according to the present invention is naturally A luxurious shine can be imparted to the tissue of the velvet fabric.

In the air nozzle B of the present invention, the air velocity distribution of the air currents is nonuniform due to the position and shape of the specially designed air supply port (B-1), and the flow force of air applied to the filament of each over- Therefore, when the material yarn passes through the air nozzle, an instantaneous loop is formed in a part of the filaments constituting the yarn, while the remaining air flow forces affect the rest The filaments of the filaments run parallel to each other in a straight line and form a layer. In this process, the filaments are tangled with each other due to different air flow forces, resulting in a naturally more disturbed shape compared to the conventional air jet texturing yarn.

In the air texturing apparatus, the overfeed rate, which is the speed ratio before and after the air nozzle (B), is conventionally controlled in the range of 12 to 18%. If the overfeed rate is low, the degree of loop effect is insufficient. However, in the air nozzle designed specifically according to the present invention, the overfeed rate can be freely adjusted, and even when the core yarn and the effect yarn are formed of the same material without using different kinds of yarns as in the conventional art, .

In addition to the structure change of the air nozzle B of the present invention, the above-described loop manifestation effect is greatly influenced by the operating conditions of the manufacturing process, and therefore, it is necessary to adjust operating conditions before and after the air nozzle B.

3, the core yarn wound around the krill is divided into a core yarn first feeding roller (-1) and a core yarn second feeding roller (-2) And the effect yarn B is supplied to the air nozzle B through the first supply roller 1 and the second supply roller 2 of the effect yarn After the core yarn (A) and the effect yarn (B) are air-textured in the air nozzle (B), they are heated and set in the heater (La) between the first discharge roller (Bar).

At this time, the speed ratio between the core yarn second feeding roller (-2) and the first discharge roller (c) (core yarn second feeding roller speed - first discharge roller speed) / first discharge roller speed x 100} 15 (Second discharge roller speed - first discharge roller speed) / first discharge roller speed x 100} 4.0 to 5.5% between the first discharge roller (c) and the second discharge roller It is preferable that the speed ratio between the second discharge roller (e) and the winding roller (bar) {(winding roller speed - second discharge roller speed) / second discharge roller speed x 100} is 9 to 10%.

In the air texturing apparatus, the tension of the core yarn (A) and the effect yarn (B) supplied to the air nozzle (B) is a very important factor for forming the loop of the air jet texturing yarn, So that the shape of the loop is varied according to the speed ratio between the core yarn second supplying roller (-2) and the first discharging roller (c) in the above speed ratio, and the effect yarn The difference in the feed rate between the core yarn (A) and the effect yarn (B) varies according to the speed ratio, that is, the speed ratio between the second yarn supplying roller (2) and the first yarn discharging roller Various irregularities can be produced on the surface.

Further, the speed ratio between the first discharge roller (C) and the second discharge roller (E) affects the heat setting time in the heater (R) and the speed ratio between the second discharge roller Affects the tension that winds the air jet texturing yarn on the bobbin after the air-texturing process, and is involved in the maintenance and damage of the formed loop shape.

At this time, it is preferable to set the production speed of the air jet texturing yarn (first discharge roller speed) to 350 to 450 mpm (meters per minute) and the heater (La) to operate at 160 to 180 ° C., Pressure air at a different angle than the conventional one at different positions of the material yarn passage in the blower B to optimize the air-permeability by optimizing the over-feed rate before and after the air nozzle B, before and after the heater (R) And air jet texturing yarns optimized for the paper texture properties of the velvet fabric can be manufactured because the extensibility is not lower than that of the conventional air jet texturing yarns and the bulge property is not decreased by the tension.

Further, it is possible to precisely adjust the overfeed rate according to the rollers (the core yarn second supply roller, the effect yarn second supply roller, and the first discharge roller) that feed and discharge the yarn to the air nozzle, The surface of the conventional roller C has a mirror-like surface with a smooth surface. Therefore, even when the same overfeed rate is given due to a severe frictional resistance during traveling of the material, surface frictional force generated between the roller surface and the filament There is a drawback that it is not applicable.

Thus, the surface of the roller can be surface-irregularized in the form of an orange ball like the roller D in Fig. 4, thereby minimizing the surface friction between the roller and the workpiece, thereby providing an optimized over- The texturing effect can be maximized.

FIG. 5 schematically shows a loop shape (E) of the conventional air jet texturing yarn and a loop shape (F) according to the present invention. The air jet texturing yarn (E) the air jet texturing yarn F of the present invention is formed in a disordered manner at a low height from the center of the yarn to provide a high esthetic natural surface effect.

In general, the air jet texturing yarn has a smaller strength as compared with a material yarn, and a decrease in the strength is increased as the air pressure and the over feed rate are increased. By changing the air nozzle, the overfeed rate, And it is possible to reduce the decrease in the strength of the air jet texturing yarn and to form a fine fine fleece loops on the surface of the air jet texturing yarn as a whole so that the stretchability is low compared with the conventional air jet texturing yarn, To give a soft touch and appearance and physical properties show properties similar to spinning yarn.

Next, the velvet fabric is woven by using the air jet texturing yarn produced as described above as a fabric for fabricating the velvet fabric.

A velvet fabric is a structure in which a certain length of a file is formed in a tissue composed of a weft and a slope, and an externally exposed file plays an important role in determining the characteristics of the velvet fabric.

In order to maintain the luxurious characteristics of the velvet fabric, it is important to maintain the standing state of the file and to prevent the paper organization from being exposed to the outside by the file. In order to increase the standing of the file, If there is a problem that the tactile feeling becomes stiff and the number of the file is increased in order to cover the tissue with the file, the tactile feeling is not smooth with the increase of the manufacturing cost.

In order to solve this problem, in the present invention, the air jet texturing yarn manufactured as described above is used as the warp or weft of the fabric constituting the fabric of the velvet fabric, thereby maximizing the morphological stability and aesthetics of the fabric.

Preferably, the warp and weft of the fabric constituting the paper structure has a fineness of 70 denier or more, and if the fineness of the paper structure is less than 70 deniers, the bending strength is low and the shape stability of the fabric is maintained And the surface area of the fine loops of fine hairs formed on the surface of the air jet texturing yarn is reduced and the aesthetic effect is deteriorated.

In the present invention, the air jet texturing yarn used in the present invention has air pressure, over feed rate, and surface pressure applied to a yarn in a specialized air nozzle. By minimizing the frictional force and forming fine loose-loop loops on the surface of the air jet texturing yarn, the mechanical strength inherent in the synthetic fibers is maintained, and the loop structure of the paper is softened by the looping effect of the surface, Can be given.

The warp and weft constituting the paper tissue have a strength of not less than 3 gf / d (load / denier) so as to firmly support the pile structure and the pile has a fineness of 75 denier or more, a denier of 200 denier or less, and a strength of less than 3 gf / So as to have a soft touch.

As described above, a velvet fabric composed of an air jet texturing yarn having a fineness of at least 70 denier and a strength of at least 3 gf / d of warp or weft forming the ground structure is deformed into an angular shape, but due to the morphological stability of the air jet texturing yarn constituting the ground structure, Even when the tissue is not easily exposed to the outside and some of the ground structure is exposed at the angled portion, the air jet texturing yarn can maintain the beautiful appearance of the velvet fabric due to the bulky feel and the high gloss property.

Nylon or polyester air jet texturing yarns having a high or low tilt of the ground structure are used as the types of the fibers constituting the velvet fabric of the present invention, and the pile is acetate yarn, dull). Acetate yarns are advantageous in that they have better covering properties than nylon yarns and polyester yarns having a circular cross section because the cross section of the acetate yarn is not sharp and rounded, so that the feel is smooth and the cross-sectional shape is corrugated.

Since the velvet fabric has a complicated post-dyeing process compared to general fabric in the form structure and it is not easy to express a clear pattern through post-dyeing, when all kinds of fastness such as color fastness and washing fastness are required along with color expression, It is preferable to use an acetate raw material.

Conventional velvet fabrics of 120 denier or less acetate can be woven by a cam-type sheathed drive device, but a velvet fabric composed of an air jet texturing yarn of 70 denier or more, which has many hairs and loops on its surface, It is difficult to work and it is not easy to make the length of the file constantly and precisely.

In addition, the cam-type sheathed drive device has a merit in that the file is highly upright, but there is a limitation in pattern diversification and there is a disadvantage that the paper tissue is leaked to the outside. When the dobby sheath drive device is used, At this time, the load on the driving device increases and the warp density can not be increased sufficiently. When the warp tension is increased, quality defects of yarn and pile fabric occur.

Therefore, it is preferable to weave the ground structure and the file structure of the velvet fabric according to the present invention by selectively combining the cam type sheave driving device and the dobby sheath driving device. In the velvet loom, both the cam type sheathed driving device and the dobby sheathed driving device It is possible to manufacture the fabric by selectively connecting the ground structure and the file structure to either one of the cam type or the Doby type sheave driving device or to selectively manufacture these sheath driving devices in combination, Various types of velvet fabrics can be made, such as making the density of the tissue tissue denser or looser, making the file rigid in the tissue tissue or making the file stand upright.

Hereinafter, a velvet loom having a cam type sheathed driving device for weaving a velvet fabric and a dobby sheathed driving device integrated with the present invention will be described.

[

The power transmitting portion 50 is constituted by a chain gear, a chain and a bevel gear for driving the dobial sheath drive device 10 and the cam-type sheathed drive device 20. [

An air jet texturing yarn was prepared in the same manner as above except that polyester yarn was supplied to an air nozzle (B) in place of nylon yarn, and the yarn number and filament count of nylon yarn and polyester yarn were changed to 3 gf / A nylon air jet texturing yarn with a fineness of 70 denier and a polyester air jet texturing yarn with a fineness of 80 denier.

Next, a grounding weave was connected to the cam-type sheathed driving device, weaving the ground tissue using the above prepared 80 denier polyester air jet texturing yarn as the warp, and the 70 denier nylon air jet texturing yarn as the weft, The filamentous shear drive was connected to a pile sheeting and filed with an acetate yarn with a fineness of less than 3 gf / d and a fineness of 135 d / 34 F and a filament count of 118 o / inch in an oblique direction and 102 o / Was applied to the tissue to prepare a 85% velvet fabric with a cover factor (4 x pile fiber cross sectional area x number of pile per unit area per unit area x 100).

<Test Example>

The physical properties of the velvet fabric prepared in the above examples were measured using a KES-F7 Labo tester (Kato Tech, Japan).

The measurement result is shown in Fig. 10, and the total hand value (THV) is a value expressing quality and quality by integrating the feel of touching the fabric with the visual and aesthetic sense at the time of viewing, The higher the value, the better the characteristic. As shown in FIG. 10, the velvet fabric of the embodiment according to the present invention is measured to be 2.93, which indicates excellent quality in terms of tactile and visual quality.

The KOSHI value is a measure of the stiffness of the fibers. The KOSHI value indicates the sense of plasticity, repulsion, and elasticity due to the touch of the hand. The higher the KOSHI value, the higher the repulsive force and elasticity. And the velvet fabric of the embodiment is measured to be 11.11, so that it can be seen that the velvet fabric of the embodiment according to the present invention has a high uprightness and the shape can be maintained even when the external force is repeatedly operated.

When the velvet fabric of the above embodiment was placed on a flat surface and the surface of the fabric was observed with naked eyes, the paper texture was not visible. When the paper texture was brought into close contact with the angled corners, the air jet texturing The company's bulky feel and luxurious luster matched the pile organization, so visual damage to the appearance was minimal and the luxurious feel of the velvet fabric was maintained.
