Japanese Patent Application No. 2000-204580 (5th and 6th pages, FIG. 5)

However, since such a functional fiber yarn is more expensive than a general fiber yarn, there is a problem that the manufacturing cost and the product cost are high.
In addition, since there are existing areas of use in thickness and density depending on the application used, and the product has been commercialized based on this, for example, it is optimal to take advantage of the deodorizing properties of the deodorizing fiber yarn. It does not necessarily correspond to the density and may be commercialized using more deodorizing fiber yarn than necessary.

  This invention is made | formed in view of said situation, The place made into the objective is to provide the deodorizing cloth provided with the favorable deodorizing effect, aiming at the cost reduction.

  The characteristic constitution of the first deodorizing fabric of the present invention is that the deodorizing fiber yarn is exposed on at least the surface of the fabric.

  According to such a configuration, for applications that require a deodorizing effect on the surface of the fabric, it is possible to manufacture and handle a deodorizing fabric in which the deodorizing fiber yarn is exposed on the surface of the fabric. For applications that require a deodorizing effect, it is possible to produce a deodorizing fabric in which the deodorizing fiber threads are exposed on both the front and back sides of the fabric.

  Therefore, since the deodorizing function of the deodorizing fiber yarn used for the cloth can be used for a necessary surface, it is possible to construct a deodorizing cloth with high use quality without waste.

  The characteristic configuration of the second deodorizing fabric of the present invention is that the ground yarn of the fabric is composed of a front yarn and a back yarn, and a pile group protruding outward in a loop shape with the front yarn. It is knitted and the surface yarn is composed of deodorizing fiber yarn.

According to such a configuration, the pile yarn combined with the front yarn protrudes outward in a loop shape and the surface of the yarn is exposed so that it can be easily exposed to the air. Therefore, the deodorizing fiber yarn has a sufficient deodorizing effect. It can be used for.
In addition, since the pile yarn is used as the front yarn, the deodorizing effect can be maintained even on the fabric surface excluding the pile forming portion.
In addition, since the back yarn forming the back surface is configured not to use the deodorizing fiber yarn, a fabric structure that concentrates the deodorizing effect only on the surface side of the fabric can be formed.

  Therefore, there is no deodorizing function on the back side of the fabric, and a deodorizing function can be provided on the surface side of the fabric. By using the fabric surface facing the deodorizing target side, a pile using deodorizing fiber yarn for all of the ground yarn Compared to fabrics, it provides a deodorizing effect that is less wasteful, and it is not necessary to use deodorizing fiber yarns, which are more expensive than general fiber yarns, for all ground yarns. .

  According to the third deodorizing fabric of the present invention, the ground yarn of the fabric is composed of a front yarn, a back yarn, and a pile yarn, and the outer yarn is outwardly looped by the front yarn and the pile yarn. The pile group which protrudes in this way is formed, and at least the pile yarn of the surface yarn and the pile yarn is composed of a deodorizing fiber yarn.

According to such a configuration, the deodorizing effect is greater when both the pile yarn and the front yarn are made of the deodorizing fiber yarn than when only the pile yarn is made of the deodorizing fiber yarn. Therefore, deodorizing fabrics having different deodorizing effects can be formed.
Moreover, since at least the pile yarn of the surface yarn and the pile yarn is composed of the deodorizing fiber yarn, the pile forming part is exposed and is in a state where it is easy to touch the air, so that the deodorizing effect of the deodorizing fiber yarn is sufficient. Can be used.
Further, even on the surface of the fabric excluding the pile forming portion, a deodorizing function can be formed on the surface of the fabric in which at least the pile yarn of the surface yarn and the pile yarn is composed of the deodorizing fiber yarn.
Further, since the deodorizing fiber yarn is not used for the back yarn forming the back surface, a fabric structure that concentrates the deodorizing effect only on the surface side of the fabric can be formed.

  Therefore, there is no deodorizing function on the back side of the fabric, and a deodorizing function can be provided on the surface side of the fabric. By using the fabric surface facing the deodorizing target side, a pile using deodorizing fiber yarn for all of the ground yarn Compared to fabrics, it provides a deodorizing effect that is less wasteful, and it is not necessary to use deodorizing fiber yarns, which are more expensive than general fiber yarns, for all ground yarns. .

Hereinafter, an embodiment of the soundproofing / soundproofing material of the present invention will be described with reference to the drawings.
[First Embodiment]
The deodorizing fabric of this embodiment is composed of a pile fabric A in which a pile 1 is piled on a net 1 made of knit.

  As shown in FIG. 1, the ground yarn constituting the pile fabric A is a surface yarn made of a single 20th to 30th cotton yarn or cotton acrylic blended yarn or a 20th to 30th wool yarn or wool acrylic blended yarn. 1a, and composed of elastic yarn (FTY) as a single back yarn 1b made of 20 denier polyurethane and 70 denier nylon, and the pile yarn 2 is composed of the front yarn 1a. Similarly to the front yarn 1a, it is composed of a single 20th to 30th cotton yarn or cotton acrylic blended yarn or a 20th to 30th wool yarn or wool acrylic blended yarn. The pile P group is formed by projecting the front yarn 1a outward in a loop shape.

  In addition, the proportion of the deodorizing fiber yarn in the pile fabric A of this embodiment, that is, the mixing ratio is about 25% to about 40%. A generally known deodorizing fiber yarn is used.

  This pile fabric A has a structure in which the deodorizing fiber yarn is not used for the back yarn forming the back surface, so that the deodorizing effect is concentrated only on the surface side of the fabric.

  Here, in the pile fabric A, when the deodorizing fiber yarn is used for all the ground yarns, the mixing ratio, which is the ratio occupied by the deodorizing fiber yarn of the fabric, is 100%, and the deodorizing fiber yarn is used for the back yarn The mixing ratio also changes depending on the knitting method of the pile fabric A, such as the protrusion of the pile forming portion that is a pile raising portion, and the knitting interval of the pile P group, each of the front yarn 1a and the back yarn 1b The mixing ratio varies depending on the number of yarns used and thread thickness.

According to such a configuration, the deodorizing fabric is constituted from the pile fabric A, the deodorizing fiber yarn is used for the pile yarn 2, and the pile yarn 2 protrudes outward in a loop shape so that the yarn surface is exposed. Therefore, the deodorizing effect of the deodorizing fiber yarn can be fully utilized.
Moreover, since the pile yarn 2 is constituted by the front yarn 1a, the deodorizing effect can be functioned even in the knitted fabric portion excluding the pile forming portion.

Examples of the use of the pile fabric A include, for example, underwear, incontinence underwear, underwear, pajamas, socks, towels, handkerchiefs, scarves, sportswear, sheets, masks, It can be suitably used for product lining materials, clothing core materials, and the like.
[Second Embodiment]
The deodorizing fabric of the second embodiment will be described with respect to differences from the first embodiment, and the same components will be denoted by the same reference numerals, and the details thereof will be omitted.

  The deodorizing fabric of this embodiment is composed of a pile fabric A in which a pile 1 is piled up with a surface yarn 1a and a pile yarn 2 on a net 1 made of knit.

  As shown in FIG. 2, the ground yarn constituting the pile fabric A is composed of a single 20th to 30th cotton yarn or cotton acrylic blended yarn or a 20th to 30th wool yarn or wool acrylic blended yarn as a yarn material. The front yarn 1a is made of deodorizing fiber yarns, and the elastic yarn (FTY) is used as one back yarn 1b made of 20 denier polyurethane and 70 denier nylon. Similarly to the surface yarn 1a, it is composed of a single 20th to 30th cotton yarn or a cotton acrylic blended yarn or a 20th to 30th wool yarn or a wool acrylic blended yarn with a deodorizing fiber yarn as a yarn material. The pile P group is formed by projecting each pile forming portion of the surface yarn 1a which is the ground yarn constituting the pile fabric A and the pile yarn 20 outward in a loop shape. Here, in this embodiment, an example is described in which a deodorizing fiber yarn using the same yarn material is used for the surface yarn and the pile yarn constituting the pile P. For example, a yarn material thicker than the surface yarn is used. The pile P group may be configured to have a volume using.

  Further, deodorizing fiber yarns are used for the surface yarn 1a and the pile yarn 2, and the surface yarn 1a and the pile yarn 20 protrude outward in a loop shape so that the surface of the yarn is exposed. The deodorizing effect of can be fully utilized.

  Furthermore, since the surface yarn 1a and the pile yarn 20 are knitted in the knitted fabric portion excluding the pile forming portion, a deodorizing function can be formed on the fabric surface.

  Since this pile fabric A has a structure in which the deodorizing fiber yarn is not used for the back yarn 1b forming the back surface, the back yarn 1b is exposed on the knitted back surface, and the front yarn 1a and the pile are on the surface. The yarn 20 is exposed, and a fabric structure that concentrates the deodorizing effect only on the surface side of the fabric can be formed.

Further, the proportion of the deodorizing fiber yarn in the pile fabric A of this embodiment, that is, the mixing ratio is about 50%.

  As a result of an experiment in which the pile fabric A of this embodiment was used as a test piece and this was housed in a sealed space with an ammonia concentration of 100 ppm and the ammonia concentration was measured after 2 hours, the result was less than 0.5 ppm after 2 hours. The deodorizing property was measured.

  The same experiment was conducted for acetic acid and isovaleric acid, and similar good results were measured.

  According to such a configuration, since both the pile yarn 20 and the surface yarn 1a forming the pile P group are made of the deodorizing fiber yarn, the ratio (mixing ratio) of the deodorizing fiber yarn to the fabric is about 50. %, And most of them are concentrated on the surface of the dough. Therefore, a deodorizing effect without waste can be obtained by using the surface in a face-to-face state for the object to be deodorized.

In the deodorizing fabric A of the second embodiment, the example in which the surface yarn 1a and the pile yarn 20 constituting the pile P are constituted by the deodorizing fiber yarn has been described, but only the pile yarn 20 is used as the deodorizing fiber. In this case, it is possible to reduce the mixing rate as compared with the case where the front yarn 1a and the pile yarn 20 are constituted by deodorizing fiber yarns, and applications that do not require a large deodorizing effect. Can be used.
Further, since the amount of the deodorizing fiber yarn, which is more expensive than the general fiber yarn, is reduced as the mixing ratio is reduced, an inexpensive deodorizing fabric can be formed while having a deodorizing effect.
