The present invention relates to a velvet woven fabric having excellent appearance and uprightness,

The present invention relates to a velvet fabric having an excellent upright stiffness of a pile fabric and having a beautiful appearance. The present invention relates to a velvet fabric having an excellent standing property of the pile yarn and maintaining a standing state of the pile yarn as much as possible to exhibit a high quality surface effect peculiar to the velvet fabric, , The fabric is not exposed to the outside and exhibits a rich surface effect.

Generally, a velvet fabric refers to a fabric which is formed by cutting a central portion of a pile fabric formed on a pile fabric so that a pile (fine hair) is formed on one side of the fabric. Such a velvet fabric is preferred as a garment have. In general, velvet fabrics are capable of manifesting a rich surface effect by making the texture of the surface not to be exposed and forming a directionality in the pile to give a slight glossiness, and in addition to being able to vary the color, It is widely used for interior decoration, seat cover and stuffed toys in addition to women's and men's clothes, hats and shawls because it can give various texture.

In general, a weaving process of a velvet fabric is described as follows. That is, a paper tissue is formed by the intersection of warp and weft, a pile is formed by reciprocating the pile tissue to form a pile tissue, do.

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, depending on the length of the pile and the method of weaving, various textures can be imparted to the surface, which has been treated as a high-grade fabric.

However, when the external force is applied to the velvet fabric, the shape of the velvet fabric tends to collapse, and it is difficult to maintain a constant direction. 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 that is damaged.

In order to solve the above problems, Korean Patent Registration No. 0737975 discloses a method of using a synthetic fiber long fiber or synthetic fiber alone or a mixed fiber of natural fiber and synthetic fiber for a warp and weft of a velvet fabric, A synthetic fiber multifilament having a fineness of 1 denier or less is used, and the filament yarn is subjected to twisting, twisting or sizing to put into a weaving machine.

Fabrics having such a configuration exhibit a dry feel and a good volume feel and provide a tactile appearance and appearance similar to fabrics woven using yarns of natural fibers. However, since the fabric is different from the core yarn and the effect yarn, the fabrication process is complicated. Further, when the fabric is applied to the fabric for the fabric of the velvet fabric, the fabric is exposed to the outside, It is possible to prevent some damage to the appearance of the velvet fabric. However, since the air-texturing process of the synthetic fiber causes the strength to be lower than that of the yarn, and the air-texturing process yarn has a large elasticity, There is a problem that the standing state of the file is easily collapsed to deteriorate the luxurious and beautiful appearance inherent in the velvet fabric.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed exemplary embodiments, but is capable of other various forms of implementation. The following examples are intended to be illustrative of the present invention, Is provided to fully inform the user. Also, for convenience of explanation, the components may be exaggerated or reduced in size.

The velvet fabric is a structure in which a pile fabric 40 having a predetermined length is formed in a pile fabric 30 composed of a weft 10 and a warp 20 as shown in Fig. 1, It plays an important role in determining the characteristics.

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, There is a problem that the tactile feeling becomes stiff. When the number of the file is increased in order to cover the paper tissue with the file, the manufacturing cost is increased and the tactile feeling is not smooth.

Therefore, as the type of the fibers constituting the velvet fabric of the present invention, the warp or weft of the ground structure may be composed of either nylon yarn or polyester yarn, and the filament yarn may be composed of acetate yarn. The nylon yarn and the polyester yarn have the advantage of being able to produce a solid ground structure with high strength. In addition, velvet fabrics have a difficulty in post-dyeing process compared with general fabrics in shape structure, and it is not easy to express clear patterns through post-dyeing. Therefore, when various fastness such as color fastness and washing fastness, It is preferable to use a polyester encapsulant in the paper tissue.

Acetate yarns used as pile yarns are not sharper in section and are rounded, so that they have a soft feel and a wrinkled cross section, which is more advantageous than nylon and polyester having a circular cross section.

The present invention also relates to the use of high-esthetic air-textured yarn (ATY) in velvet fabrics < RTI ID = 0.0 > (ATY) < / RTI > to improve the unique cold feel of synthetic fibers used in paper tissues and the problem of excessive surface gloss & To a technique for applying the present invention to a tissue of tissue.

In order to manifest the bulky characteristics of the yarn in the yarn processing process, a false-twisting method in which the yarn is twisted and twisted is applied, or two different yarns are entangled with high-pressure air to induce an artificial surface change The resulting air texturing ice-cream is the usual method.

However, in the present invention, the material yarn made of the same material, that is, the core yarn and the effect yarn are passed through the air entangling nozzle to form a natural loop, and the air filament is blown into the filament of the material yarn, Can be manufactured. That is, it is most preferable that the nylon air jet texturing yarn of the present invention uses a yarn made of the same material as the core yarn and the effect yarn. However, by using the texturing device including the air nozzle B specially designed according to the present invention, (Volume feeling) is imparted even when air jet texturing of the branch yarn is performed. Therefore, it is possible to manufacture a velvet fabric having an excellent uprightness and a beautiful appearance even if two different kinds of yarns are used for the core yarn and the effect yarn as in the prior art, and the core yarn and the effect yarn are made of the same material It is possible to manufacture a velvet fabric which is provided with a sufficient feeling of bulkiness (volume) even when it is used, and has an excellent standing property of the pile texture and a beautiful appearance. That is, in the present invention, even if at least one of the core thread and the effect yarn constituting the nylon air jet texturing yarn is composed of nylon multifilament, it is sufficient by the texturing apparatus including the air nozzle B It is possible to produce a velvet fabric having an excellent appearance and an excellent uprightness of the desired pile fabric. Thus, throughout the description of the present invention, the nylon air jet texturing yarn refers to an air jet texturing yarn made of nylon multifilament of at least one of core yarn or effect yarn.

In addition, the present invention can be applied to replace the conventional velvet fabric paper with the fabric for producing the air jet texturing yarn, thereby reducing 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 and to maintain the file structure uniformly and stably so as to manufacture a velvet fabric in which the uprightness of the pile yarn is maintained.

2. Description of the Related Art [0002] Conventional air-textured yarns (ATY) are generally classified into air yarns by separating two types of yarns into a core yarn yarn and an effect yarn, And then passing it through the process. In particular, the core yarn is subjected to a wetting device before being injected into the air nozzle.

The method of manufacturing an air jet texturing yarn of the present invention is a method of manufacturing an air jet texturing yarn having a thread guide identical to that of a conventional air texturing process but using a specially designed air nozzle without using a wetting device, It is possible to form a bell-like feeling and a natural disorder in the entirety of the above-mentioned material. In addition, the air jet texturing yarn manufactured has a soft touch feeling by a specialized nozzle, and when used in the paper web of the velvet fabric, the density of the pile is formed to play an important role in determining the uprightness and the high gloss characteristics. That is, as described above, even if the core yarn and the effect yarn are made of two different materials in the same manner as the conventional ATY (air texturing yarn) manufacturing method, or the core yarn and the effect yarn are made of the same material, A texturing device including an air nozzle (B) specially designed can be used to provide a nylon air jet texturing yarn with a sufficient embossing feeling so that it is possible to produce a velvet fabric having an excellent standing property and a beautiful appearance . That is, even when at least one of the core yarn and the effect yarn constituting the nylon air jet texturing yarn is composed of nylon multifilament, sufficient yarn feel is exhibited by the texturing device including the air nozzle (B) So that it is possible to manufacture a velvet fabric having an excellent uprightness and a beautiful appearance of a desired pile fabric.

Fig. 3 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.

3, the air nozzles A-1 and B-1 are arranged at an angle of 120 ° with respect to the air nozzles A-1 and B- 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. According to the structure of the air nozzle of the present invention as described above, not only the material made of the same material but also the material yarn made of different materials can sufficiently exhibit the winding feeling, the feeling of bell feel and the elastic recovery rate, and the nylon air Weaving velvet fabrics by weaving the ground tissue using jet texturing yarns makes it possible to produce velvet fabrics with excellent upstanding and good appearance of pile tissue.

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) The air inlet A-1 is disposed at the same position in the conventional air nozzle A so that the loop shape is large and strong. However, the nylon air jet texturing yarn of the present invention has the air inlet A- By varying the angle and position, the height of the loop is low and the width of the fiber is widened in the left and right direction, so that natural crimp feeling and pile feeling are formed and the elastic recovery rate is increased. In particular, when the nylon air jet texturing yarn of the present invention is used as a weft yarn or a warp yarn for the weaving of velvet fabrics, it provides the effect of tightly winding filaments by loops formed on the yarns, The shape stability is secured.

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, Pressure air to be supplied to the air supply port (B-1), air of 7 to 9 bar is required to be 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 ratio of 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 the loop effect is insufficient. However, in the air jet texturing apparatus including the specially designed air nozzle of the present invention, since the over feed rate can be freely adjusted, it is possible to use the core yarn and the effect yarn in the same manner as in the prior art, The loop can be sufficiently expressed in the air jet texturing yarn. In the air texturing apparatus according to the present invention, the overfeed ratio, which is the velocity ratio before and after the air nozzle B, is in the range of 15 to 25%. The nylon air jet texturing yarn of the present invention exhibits an abundant surface effect unique to the velvet fabric by expressing a loosely shaped loop from the above-mentioned over feed rate. 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.

Fig. 4 schematically shows a process for manufacturing an air jet texturing yarn according to the present invention, wherein the core yarn wound around the krill comprises a core yarn first feeding roller (-1) and a core yarn second feeding roller 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, the over feed rate can be precisely adjusted according to the rollers (the core yarn second supply roller, the effect yarn second supply roller, and the first discharge roller) supplying and discharging 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.

Accordingly, the surface of the roller can be surface-irregularized in the form of an orange ball like the roller D in Fig. 5, thereby minimizing the surface friction between the roller and the workpiece. Thus, an optimized over- The texturing effect can be maximized.

Fig. 6 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. Also, in the present invention, the paper tissue can be woven by using a nylon air jet texturing yarn or a polyester original yarn. The polyester original yarn can increase the color fastness to the velvet fabric, which is not easy to express a clear pattern, and the color fastness such as light fastness and washing fastness.

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 such a problem, in the present invention, it is possible to maximize the morphological stability and aesthetics of the paper tissue by using nylon air jet texturing yarn or polyester original yarn as the warp or weft constituting the paper tissue of the velvet fabric, It is possible to manufacture a velvet fabric having an excellent uprightness and a beautiful appearance.

Preferably, the warp and weft of the fabric constituting the paper structure has a fineness of 50 denier or more, and when the fineness of the paper structure is less than 50 deniers, the bending strength is low, and the external force is repeated, 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 the 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 fabric, and the pile paper has a fineness of 75 denier or more and a strength of less than 3 gf / It is preferable to have a touch.

As described above, the fineness of the warp or weft constituting the ground structure is 50 denier or more, the air jet texturing yarn of the strength of 3 gf / d or more, or the polyester origin yarn, and the filament yarn has a fineness of 75 denier or more and less than 3 gf / d , Even though the velvet fabric is deformed into an angular shape, the structure of the air jet texturing yarn constituting the ground structure is not easily exposed to the outside, and even when some of the ground structure is exposed at the angled portion, the air jet texturing Because of the bulky feel of the yarn and the luxurious gloss properties, the beautiful appearance of the velvet fabric can be maintained.

Typically, the cam structure of the velvet fabric and the cam structure of the pile fabric during the weaving operation is excellent in the uprightness of the pile but there is a limitation in pattern diversification and there is a disadvantage that the pile tissue is leaked to the outside. In this case, the inclination density should be increased in order to enhance the uprightness of the file. In this case, the load on the driving device is increased so that the inclination density can not be increased sufficiently.

Therefore, it is preferable that the ground structure and the pile structure of the velvet fabric according to the present invention are woven by selectively combining the cam type sheave driving device and the sheave type sheave driving device. That is, it is possible to manufacture the velvet fabric loom by providing both the cam type sheave drive device and the dovetail type sheave drive device, and connecting the ground structure and the file structure to either one of the cam type or dobichi type sheave type drive device, It is possible to produce the velvet fabric with a dense or loose density of the paper tissue constituting the velvety fabric and also to make the file solid in the paper tissue or to make the file stand upright And various types of velvet fabrics can be manufactured.

The velvet fabric of the present invention is characterized in that it exhibits excellent quality in terms of tactile and visual properties, has a high standing property of pile yarn and continues its shape even when an external force acts repeatedly. In addition, when the velvet fabric of the present invention was placed on a flat surface and the surface of the fabric was visually observed, the ground structure was not visible. When the ground structure was exposed by closely contacting the corner with the angled corners, the air jet texturing company The voluminous and luxurious luster characteristics are combined with the pile organization, which visually impair the appearance of the appearance and maintain the elegant and luxurious feel of the velvet fabric.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
