Description

High density fabric with excellent water pressure and its manufacturing method

The present invention relates to a high-density fabric and a method for producing the same, which have excellent shape safety and surface feel, and have excellent water pressure without a coating process. High density fabric with excellent water pressure is mainly used for sports clothes such as jackets. Conventional techniques for manufacturing high-density fabrics with excellent water pressure include weaving microfibers with a single yarn fineness of 1.0 denier or less into the weft yarns and weaving them into a plain weave structure, or biaxial shrinkage produced by interweaving microfibers and high shrink yarns with single yarn fineness of 1.0 denier or less with air entanglement. There is a method of manufacturing a high-density fabric by arranging the blended yarn into a weft yarn and then weaving it into a plain weave tissue, and shrinking the high shrink yarn as much as possible in the post-processing process.

Of the existing manufacturing methods of high-density fabrics, the method of weaving microfibers with a single yarn fineness of 1.0 denier or less with the weft yarns and then weaving them with plain weave is the result of warp and weaving due to the use of three denier yarns during weaving. Not only is it lowered, but it is woven into plain weave, so the weft point of weft yarn is so high that it is difficult to make high density weaving with a coverage factor of 29 or more.

In addition, in order to prevent the warping phenomenon as described above, a method of using a warp yarn after attaching an arc after improving the converging property by air-crossing microfiber yarns has been proposed. It remains as it is, and causes small holes (hereinafter referred to as pinholes) on the fabric. Such a pinhole is a factor of lowering the water pressure of the fabric.

Next, a method of manufacturing a high-density fabric by arranging bispun horns yarns in which microfiber yarns with single yarn fineness of 1.0 or less are mixed with air entangled as a light yarn, weaving them into plain weave tissue, and shrinking the high shrink yarns as much as possible in the post-processing process. It is excellent in weaving due to the air entanglement of microfibers and high shrink yarns in silver processing, and it is difficult for the plain weave on the loom to exceed 29 or more. However, the entanglement point is formed by the air entanglement, and these act as pinholes on the fabric, which acts as a factor of lowering the water pressure.In addition, the manufacturing cost increases due to excessive shrinkage of high shrinkage yarns during processing, and the internal voids of the fabric increase, resulting in the fabric's water pressure. This has a problem of deterioration.

It is intended to provide a high-density fabric and a method of manufacturing the same, which have no pinhole and excellent compactness, have excellent water pressure without a coating process, and have excellent shape stability and surface feel.

FIG. 1 is an organization chart of plain weave, and FIG. 2 is a cross-sectional view showing a state of weft weave in a fabric woven into plain weave, and FIGS. 3 to 6 are organization charts of the fabric of the present invention composed of a plain weave and a back face thereof. 7 is a cross-sectional view showing the inclined weft arrangement on the fabric of the present invention.

1 to 7, 1 is weft 1, 2 is 2 weft, 3 is 3 weft, 4 is 4 weft, 5 is 5 weft, 6 is 6 weft And 7 is the slope.

The present invention relates to a high-density fabric having excellent shape stability and surface feel, and having excellent water pressure without a coating process, and a manufacturing method thereof.

Since the water pressure of the fabric depends on the density of the fabric and the presence of pinholes on the fabric, we have to weave it with high density while suppressing the occurrence of pinholes on the fabric.

The present invention relates to a microfiber yarn having a single yarn fineness of less than or equal to 1.0 denier, or a biaxial blended yarn containing 50% or more of the microfiber yarn, wherein the fabric surface is composed of a main fabric and the fabric fabric is a plain weave. will be. In another aspect, the present invention by using a microfiber yarn having a single yarn fineness of 1.0 denier or less in the warp and / or weft yarn or a biaxial blended yarn containing 50% or more of the microfiber yarn is woven into the tissue of FIGS. 3 to 6 to produce a high-density fabric It is about how to.

In the present invention, in order to improve the water pressure of the fabric by densifying the tissue, a microfiber yarn having a single yarn fineness of 1.0 denier or less as a warp and / or weft yarn or a biaxial blended yarn containing 50% or more of the microfiber yarn is used.

Microfiber is a nylon filament or polyester filament. If the fine yarn fineness of the microfibers exceeds 1.0 denier or less than 50% of the microfibers in the biaxial blending yarn are not included, the fabric texture cannot be tasted and the water pressure of the fabric decreases.

Using such yarns as warp and / or weft yarns, the surface of the fabric is woven into the tissue of FIGS.

When weaving only the plain weave tissue, the morphological stability of the fabric is improved, but it is difficult to manufacture a high-density fabric with a coverage of 29 or more due to the interwoven points of the weft yarns.

FIG. 1 is an organization chart of plain weave, and FIG. 2 is a cross sectional view showing a state of warp yarn arrangement on a fabric woven into plain weave. Every time the weft hanol is enclosed, the odd and even healds alternately move up and down.

As a result, the weft yarn number 1 (1) and the weft yarn number 2 (2) are alternating with an inclination (7) therebetween, resulting in an excessive intersection point on the fabric. Therefore, it is difficult to increase the density of the fabric. On the other hand, when weaving into a twill or runner tissue to reduce the fabric point of fabric, the fabric point is reduced and the coverage of fabric is improved, but the shape stability of the fabric is lowered, making it unsuitable for use in sports clothes such as jackets. .

In the present invention, in order to impart excellent shape stability to the fabric and at the same time excellent density, the fabric of the fabric of Figures 3 to 6 so that the surface of the fabric consists of a main fabric and the back of the fabric can be composed of plain weave.

3 to 6 are sectional views of the fabric of the present invention, and FIG. 7 is a cross-sectional view showing a state of the phase arrangement on the fabric woven into the structure of FIG.

When weaving weft yarn 1 (1), weft weft yarn 2 (2) and weft yarn 2 (2) are arranged next to weft yarn 1 because weft yarn 2 (2) does not form an intersection point with weft yarn 1 Are arranged under weft # 1 (1). When weft weft No. 3 (3), weft No. 3 (3) has a plain weave structure with the weft No. 2 (2). At this time, the weft yarn No. 2 (2) and the weft yarn No. 3 (3) has a number of teaching points to improve the shape stability of the fabric.

When weft weft 4 (4) enters the weft 4 (4) has a weft point 3 (3) and 1/5 of the weaving point compared to plain weave can be arranged as close to the weft 3 (3) as possible to increase the density Do.

The weft yarn 5 (5) has the same behavior as the weft yarn 2 (2) and the weft yarn 6 (6) has the same behavior as the weft yarn 3 (3), the surface of the fabric is a surface constituting the main job It mainly comes out, and the side constituting plain weave is mainly coming out.

In the high-density fabric of the present invention, since the surface is composed of a main weaving fabric and the back surface is composed of a plain weave, a difference in the feel between the surface and the back surface is expressed. The surface composed of the main fabric is softer than the back side due to its excellent fluidity. In addition, the back surface is composed of plain weave is formed a lot of teaching points to give shape safety to the fabric.

In the case of the conventional woven fabric of plain weave, the shape safety of the fabric is excellent due to many teaching points, but the touch of the surface and the back is not soft. The fabric of the present invention, which has a back surface composed of plain weave and a surface composed of a main weaving fabric woven in the tissues of FIGS. 3 to 6, is an inclined and / or weft yarn that has a single yarn fineness of 1.0 denier or less. The use of blended yarns also significantly reduces the occurrence of pinholes.

This effect is considered to be due to the two-layer structure of the fabric.

The fabric of the present invention has fewer pinholes on the fabric and is capable of high-density weaving, so that the water pressure is excellent without the coating process and the back surface is composed of plain weave, which is also excellent in form stability of the fabric. In addition, the surface is composed of the main fabric, and the softness is soft with the fine fluidity of fine fiber. Furthermore, we can use microspun yarn with single yarn fineness of 1.0 denier or less and biaxially blended blended yarn with air blended yarn with high-density yarn as inclined and / or weft yarn without any problem of pinholes on fabric. You can.
