Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of weaving a composite fabric including a leno structure and a woven structure using a single beam wound with a tension-balanced yarn,

TECHNICAL FIELD The present invention relates to a composite weaving technique, and more particularly, to a technique for producing a composite fabric including a leno structure and a woven structure together.

Currently, various apparatuses and methods for producing a composite fabric have been commercialized, and various studies and developments thereof have been conducted. Such a composite fabric includes a composite fabric including a plurality of structures, a composite fabric composed of a plurality of layers, a composite fabric woven by a plurality of different yarns, and the like.

A representative example of a composite fabric comprising a plurality of tissues is a Lenovo composite fabric alternately comprising a leno structure and a woven structure. The weaving of the Lenovo woven composite fabric is accomplished using a double-beam beam, in which the leno weave yarn is wound and the woven yarn for the woven tissue is wound.

Because of the nature of the tissue, the speed at which the leno tissue yarn unwinds is faster than the speed at which the woven tissue yarn unwinds, so that a single beam of both the leno tissue yarn and the woven tissue yarn is wound, that is, a single beam ), It is difficult to weave a blended fabric including a Leno structure and a woven structure.

However, if a composite fabric including a Leno structure and a woven structure can be woven using a single beam rather than a double beam, the structure and complex weaving process of the composite weaving machine can be simplified and the work space can be reduced, The manufacturing cost of the composite fabric may be lowered, and the efficiency of manufacturing the composite fabric and the utilization of the work space may be increased.

For a better understanding of the present invention, its operational advantages and features, and the objects attained by the practice of the present invention, reference should be made to the accompanying drawings, which form a preferred embodiment of the invention, and the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a flow chart illustrating an example of a method of weaving a composite fabric including leno and woven tissue using a single beam of tension-balanced yarn wound according to the present invention. Hereinafter, the composite fabric manufacturing method will be described with reference to necessary drawings.

First, an additional tension is applied to the stretchable woven tissue yarn, and the yarn for woven tissue and the leno tissue yarn are wound into a single beam (S100). It is preferable that the yarn for woven tissue has elasticity corresponding to the difference in length of the yarn required for weaving the leno structure and for weaving the woven structure and that the tension applied to the woven tissue yarn is applied to such an extent that the stretchability is canceled Do.

In other words, the stretchability imparted to the woven tissue yarn can be determined by the difference between the rectilinear shrinkage occurring at the time of weaving the leno tissue and the straightness occurring at the time of weaving the woven tissue. As used herein, the term " rectilinear " may mean a rate at which the length of the woven fabric decreases in relation to the length of the yarn supplied at the time of weaving the fabric. This direct axis is larger in Leno tissues than in Woven tissues. This is because, in the case of the woven structure, the warp and weft are simply woven while the warp and weft are orthogonal, while the Leno structure is woven while the warp is twisted and orthogonal to the weft.

When the single beam with the stretched woven fabric yarn wound thereon is rotated, the leno tissue yarn and the woven tissue yarn are provided from the rotating single yarn (S110). Then, the leno tissue yarn and the woven tissue yarn provided from the single beam are supplied to a weaving module via a drop bar, a heald, and a body (S120). On the other hand, the yarns are yarns for constituting the inclination of the composite fabric.

At this time, the leno tissue yarn and the woven tissue yarn provided from the rotating single beam are provided at the same speed (i.e., the same length). This is because the tension applied to the woven tissue yarn is released in the weaving process and the stretchability of the woven tissue yarn is thereby developed to eliminate the difference in yarn length required for weaving the Leno and woven tissues.

Then, in the weaving module, the composite fabric including the supplied leno fabric and woven fabric is woven (S130). That is, according to the composite fabric weaving method of the present invention, stretch imparting and tension balancing yarn for woven tissue and yarn for Leno organization are taken together by taking a difference in yarn length required for weaving of the Leno and woven tissues together So that the composite fabric including the Leno structure and the woven structure can be woven.

That is, according to the composite fabric weaving method of the present invention, the configuration of the composite weaving machine and the complex weaving process can be simplified compared to the conventional composite weaving method using a double beam. As a result, the manufacturing cost of the composite fabric can be lowered, the manufacturing efficiency of the composite fabric can be enhanced, and the work space usability can be improved.

FIG. 2 is a conceptual illustration of an example of a composite fabric manufactured according to the method of manufacturing a Lenovo composite fabric according to the present invention.

Referring to FIG. 2 (a), it can be seen that the composite fabric includes a woven structure and a leno structure alternately. In this case, the stretchable woven fabric yarn and the Leno fabric yarn to which the tension is applied should be alternately arranged in the single beam.

Referring to FIG. 2 (b), it can be seen that the composite fabric includes woven fabric, hollow fiber fabric, and Leno fabric alternately. Here, the term "openworking" means an organization in which weaving is not carried out. That is, there may be a gap between the woven structure and the Leno structure in the composite fabric that is not woven. Also in this case, the composite yarn can be woven by woven yarn for woven organization yarns alternately wound with leno organization yarns in a single beam, and woven in a state where a body hole corresponding to the hollow structure is left empty.

3 is a block diagram of a composite weaving machine 100 for conceptually explaining a process of performing a composite fabric manufacturing method according to the present invention. FIG. 4 is a block diagram of a device for conceptually explaining a process of performing a conventional method of manufacturing a resonator composite fabric.

Referring to FIG. 3, a composite weaving machine 100 according to the present invention includes a single beam 110, a drop bar module 120, a shear module 130, and a body module (not shown) 140). The components of the composite weaving machine 100 shown in Fig. 3 are not required, so that the upper composite weaving machine 100 may have more or fewer components.

4, the conventional composite weaving machine 200 includes the double beams 210 and 220, the tension adjuster 230, the drop bar module 240, the shear module 250, and the body module 260). The difference between the two configurations is the presence or absence of a single beam, a double beam, and a tension adjusting device. Hereinafter, differences between the two will be described in detail.

In the composite weaving machine 100 according to the present invention, the yarn for woven tissue and the yarn for leno tissue are supplied together while the single beam 110 is rotated. Of course, as described above, the yarn for woven tissue should have the elasticity in consideration of the difference in the required amount of the yarn for leno, and the yarn must be wound to the single beam 110 in a tension-balanced state.

However, in the conventional composite weaving machine 200, the yarn for woven tissue is provided in the first beam 210, and the yarn for leno is provided in the second beam 220. In the conventional composite weaving machine 200, the yarn for woven tissue is supplied to the drop bar module 240 through the tension adjusting device 230 once more.

That is, when weaving a composite fabric including both a woven structure and a Leno structure, the composite weaving machine 100 according to the present invention uses one beam unlike the conventional composite weaving machine 200, Since the adjustment device is not required, the construction of the composite weaving machine and the complex weaving process can be simplified and the work space can also be damped. Accordingly, when the composite weaving machine 100 according to the present invention is used, the manufacturing cost of the composite fabric is lowered, the manufacturing efficiency of the composite fabric is improved, and the usability of the work space can be improved.

FIG. 5 is a view for explaining an example in which elasticity imparted to a yarn for woven tissues is calculated in the method for producing a Lenovo composite fabric according to the present invention. The stretchability imparted to the woven tissue yarn can be determined by the difference between a straight axis occurring at the time of weaving the leno structure and a straight axis occurring at the time of weaving the woven structure.

The straightness of the woven structure can be calculated according to the following equation (1).

Here, k1 is a constant indicating the degree of flatness of the woven structure.

The number of intersections per inch of the warp yarn can be calculated according to the following equation (1), and the diameter of the warp yarn can be calculated according to the following equation (3).

Here, the density may mean the number of slopes per inch.

Where N may be the number of slopes.

On the other hand, the rectilinear axis of the Leno structure can be calculated according to the following equation (4).

Here, the number of intersections per inch and the diameter of the tilt of the tilt can be calculated from Equations (2) and (2). And k2 is a constant indicating the degree of flatness of the leno structure.

In the above, the stretchability imparted to the woven tissue yarn is the same as the number of the leno tissue yarn and the woven tissue yarn, and the density of the leno tissue and the woven tissue The number of intersections per inch of the Leno structure can be determined.

Hereinafter, with reference to Equations 1 to 4, we calculate the elasticity of the yarn for woven fabric for weaving of the composite fabric including the woven fabric and the Leno fabric shown in Figs. 5A and 5B I try. Assuming that the density per inch of each of the woven structure and the leno structure is 50 and that the diameter of each of the woven fabric yarn and the leno organization yarn is 2 in total and 60 in number (that is, a single yarn number of 30) We assume that the flatness of the Leno structure is 2/3.

The diameter of the inclination is calculated as 0.0232 by substituting N = 30 in Equation (2). The number of intersections per inch of slope is calculated as 50 by substituting 50 for density, 2 for weft number per slice and 2 for slope, and 4 for each repeater in equation (3). This can be applied to both woven and leno tissues.

Substituting Equation 3 for the number of intersections per inch and the constant 2/3 of the calculated warp diameter and warp, the straightness of the woven fabric is calculated to be 0.1933. This means that a straight axis of 0.1933 centimeters per inch occurs. Dividing this by 2.54 corresponding to 1 inch, 0.761 is calculated. This means that a 7.61 percent straightening of the woven tissue occurs.

On the other hand, the rectilinear axis of the Leno structure is determined by adding (relative to the wavenumber) / (4) * (1/2), which is an additional portion of the equation (4) in Equation (4). This is because the latter part of Equation (4) is the same as Equation (3). The rectilinear axis of the Leno structure is 0.0967 centimeters more per inch than the rectilinear axis of the woven tissue. This is calculated by substituting 50, which is calculated before the number of intersections per inch of the slope, in the front part of the above Equation (4). Dividing this by 2.54, which corresponds to 1 inch, it is 0.0381, which means that the linearity of the Leno structure is 3.81% more than the Woven structure.

That is, in order to weave the composite fabric including the woven structure and the Leno structure shown in Fig. 5 into a single beam subjected to a cannulated yarn in consideration of tension balancing of the yarn, the yarn for woven tissue has a stretchability of 3.81% When a single beam is regularly formed, a tension may be applied so that the stretchability is exhibited in the weaving process, and the original may be regularized.

Figure 6 shows an example (1 repeat) of a Lenovo woven composite fabric made according to the method of making a composite fabric according to the present invention. 7 shows an organization chart of the Lenovo composite fabric shown in Fig.

Referring to FIGS. 6 and 7, it can be seen that a plurality of leno tissues and a plurality of woven tissues are alternately included in one repeat of the composite fabric. The composite fabric includes a portion of the Leno structure not including the Leno and Woven structures, which corresponds to the structure shown in FIG. 2 (b).

In the composite fabric, the warp yarns for the woven fabric of different thicknesses alternately form a woven structure. In addition, it can be seen that the gradient of the Leno structure is the same in thickness, and the position of the Reno twist through which the weft of the Leno structure passes is changed as the Leno structure is repeated.

Meanwhile, the composite fabric shown in FIGS. 5 and 6 is merely an example of a composite fabric manufactured according to the method of manufacturing a composite fabric according to the present invention, and it is possible to manufacture a composite fabric having various and different structures according to the present invention It will be readily apparent to those skilled in the art to which the present invention pertains.

Fig. 8 shows an example of a tension adjusting device 300 of a canonical device, which is able to squeeze a single beam by applying different tension to the yarn for leno organization and the yarn for woven organization in the composite fabric weaving method according to the present invention.

The tension adjusting device 300 includes a support 310, a shaft 320 vertically coupled to the center of the support 310, and a washer 330 inserted into and removed from the shaft 320. The yarn to be wound is supplied from a yarn supply source (not shown) and passes through the shaft 320 while passing through the shaft 320. The tension applied to the yarn can be adjusted by the weight (or number) of the washer 330.

In the composite fabric weaving method according to the present invention, the woven fabric yarn should be given a stronger tension than the leno fabric yarn in consideration of the stretchability to be exhibited in the weaving process. That is, tension balancing is required between the two yarns. This tension balancing can be solved by making the weight of the washer of the tension regulating device corresponding to the woven fabric yarn heavier than the weight of the washer of the tension regulating device corresponding to the leno fabric yarn.

This tension balancing can also be performed by controlling the angle (?) Formed by the yarn passing through the tension adjusting device. For example, by making the angle corresponding to the woven organization yarn smaller than the angle corresponding to the leno organization yarn, a stronger tension can be given to the woven organization yarn.

On the other hand, although not shown in the drawing, the tension balancing for the woven fabric yarn and the leno fabric yarn may be performed by giving different tension to the yarns in the tension guide bar through which the yarn passes. However, the tension balancing method between the yarns used in the composite fabric weaving method according to the present invention is not limited to the above examples.

While the invention has been shown and described with reference to certain preferred 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 spirit and scope of the invention as defined by the appended claims. This is possible.

Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
