SUMMERY OF THE UTILITY MODEL

Technical problem to be solved by the utility model

When silver threads are used as the warp threads of the woven fabric, the silver threads are blocked by the weft threads and are not easily damaged, but the silver threads are hardly visible from the outside. Therefore, the beautiful metallic luster unique to the silver thread cannot be positively utilized as a design of bedding. In addition, if the silver wire is blocked at the rear of the warp, it is difficult to exert an antibacterial action.

Therefore, an object of the present invention is to provide a bedding which has excellent antibacterial properties and also has excellent design properties.

Means for solving the technical problem

The present invention relates to bedding (bedding foods) in one form, and more particularly, to a bedding (textile) made of warp (warp) and weft (weft) by satin weave (satinweave), and sewn to a quilt lining (textile) or a quilt cover (textile) with the surface of weft with a greater float length as the outside, wherein the textile includes a region in which minimum silver thread units (word-making) are continuous, and the minimum silver thread units are silver threads (silver-containing threads) of the weft.

According to this aspect, since the bedding is configured by a woven fabric in which silver threads are not used for some of the warp threads and silver threads are used for some of the weft threads, and the satin weave is performed so that the float length of the weft threads is increased, the user can easily visually confirm the silver threads woven into the bedding. The design of the bedding is improved by the specific metal luster of the silver wires. In addition, the silver wire is not shielded at the rear part of the warp, so that the antibacterial property is improved.

In the above aspect, the minimum silver wire unit is constituted by a plurality of five-harness satin (5harness satin) weaves that are continuous in the warp yarn extending direction.

According to this aspect, the five satin weaves having the highest friction among the satin weaves are arranged in the extending direction of the warp threads to form the minimum silver thread unit, and therefore the antibacterial property and the designability are balanced with the fabric strength. Further, if the floating weft is too long, the woven fabric tends to be weak against rubbing.

In the above aspect, the silver wire contains a silver element (silver element) in an amount of 2 to 5 wt% based on the fabric.

According to this form, a bedding article having a balanced antibacterial action and silver usage amount can be provided.

Effect of the utility model

According to the present invention, a bedding excellent in antibacterial property and also excellent in design property can be provided.

Detailed Description

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, articles denoted by the same reference numerals have the same or similar structures. The bedding article 1 of the present invention is, for example, a quilt or a quilt cover. In the case where the bedding article 1 is a quilt, the inner cloth of the quilt constituting the outer layer of the quilt is composed of the silver-thread-attached cloth 10. In the case where the bedding article 1 is a quilt cover, the quilt cover is composed of a cloth 10 with silver threads.

The quilt inner cloth or the quilt cover is made by sewing a fabric woven by satin weave with the surface 10B of the weft 12 having a large length as the outer side. The utility model relates to a have a characteristic that silver-colored line cloth 10 has and be: silver wires are used for the weft wires 12 but not for the warp wires 11 (see fig. 1).

The cloth with silver threads 10 constituting the quilt inner cloth or the quilt cover is constituted by minimum silver thread units 5S continuously extending in the warp extending direction Y and the weft extending direction X, and the minimum silver thread units 5S include at least one silver thread 12 Ag. The minimum silver line unit 5S is formed by connecting the textures 5 such as five-leaf satin in the extending direction Y of the warp (see fig. 2).

Since the silver wires 12Ag are used for a part of the weft wires 12 and the satin weave is performed so that the floating length of the weft wires 12 is increased, the user can easily visually confirm the silver wires 12 Ag. The design of the bedding 1 is improved by the metallic luster unique to the silver wire 12 Ag. Further, the silver wires 12Ag are not shielded at the rear portions of the warp yarns 11, and thus the antibacterial property is improved. The silver component contained in the silver wire 12Ag is, for example, 2 to 5 wt% of the silver-wire-attached fabric 10. Next, each configuration will be described in detail with reference to fig. 1 to 4.

Fig. 1 is an enlarged plan view showing an example of a silver-thread-attached fabric 10 constituting a bedding article 1 according to an embodiment of the present invention. As shown in fig. 1, the silver-thread-attached fabric 10 is a fabric woven with warp yarns 11 and weft yarns 12 in a satin weave. The warp threads 11 extend in the Y direction. The weft yarns 12 extend in the X direction intersecting the Y direction.

A part of the weft wires 12 is made of silver wires 12Ag containing silver. The silver wire 12Ag is, for example, a wire obtained by cutting a silver foil into a long and thin strip shape. Further, the silver wire 12Ag may contain a component other than silver. For example, the silver wire 12Ag may be a wire obtained by cutting a resin film on which silver is deposited into a long, thin strip shape. For example, the silver wire 12Ag may be a strand of silver-coated resin wire.

The weft threads 12 and all the warp threads 11 except the silver threads 12Ag are formed of threads of natural fibers such as cotton or silk threads, for example. However, the material of the weft 12 and the warp 11 is not particularly limited except for the silver wire 12 Ag. For example, the warp yarns 11 and the weft yarns 12 may be synthetic fibers such as polyester fibers, or may be a yarn obtained by blending natural fibers and chemical fibers.

When the weft 12 is composed of the cotton thread 12CT and the silver thread 12Ag, for example, one silver thread 12Ag is woven in every twenty to fifty weft threads 12. Preferably, one silver wire 12Ag is woven into every twenty-five to thirty-five weft wires 12.

In the silver-wire-attached fabric 10, the silver component is contained, for example, in an amount of 2 to 5 wt%. Preferably, the silver component is contained in an amount of 4 to 5 wt%. Further, if the silver component is less than 2 wt% of the silver-wire-attached fabric 10, there is a risk that satisfactory antibacterial properties cannot be obtained. If the silver component is more than 5 wt% of the silver-containing fabric 10, the antibacterial property is not changed much although the amount of silver used increases and the cost increases.

Fig. 2 is a plan view showing a five-piece satin weave 5 constituting the silver-thread attached fabric 10 shown in fig. 1 and a minimum silver thread unit 5S in which the weave 5 is continuous in the warp extending direction Y. In fig. 2, one a is continuous with the other a. One B is continuous with the other B. One C is continuous with the other C. One D is continuous with the other D. That is, the minimum silver wire unit 5S is continuous from one end located at the upper left of fig. 2 to the other end located at the lower right.

In the illustrated example, the minimum silver line unit 5S includes a twenty-nine group of five-harness satin weave 5 and includes five silver lines 12 Ag. However, the structure of the minimum silver wire unit 5S is not limited to the illustrated example. For example, the minimum silver wire unit 5S may be configured to include six groups of the structures 5 and include one silver wire 12 Ag. For example, the minimum silver wire unit 5S may be configured to include twelve sets of the structures 5 and include two silver wires 12 Ag. In the latter case, the adjacent silver lines 12Ag may not be equally spaced.

The bedding article 1 is, for example, a feather comforter. The cloth 10 with silver threads used as a comforter lining may also be subjected to feathering so that feathers do not fly out of the comforter. Fig. 3 is a cross-sectional view schematically showing an example of the silver-wire-attached cloth 10 before the feather-proof processing. Fig. 4 is a cross-sectional view schematically showing an example of the silver-wire attached cloth 10 after the feathering prevention process.

As shown in fig. 3, in the silver-thread-attached fabric 10 in a state after weaving (woven using a machine), the silver threads 12Ag sandwiched by the cotton threads 12CT are curved in an arch shape. In the feather-proof process, the cloth 10 with silver wires is compressed by the roller to lower the air permeability of the cloth 10. As shown in fig. 4, in the silver-wire attached fabric 10 after the feathering process, the cotton wires 12CT and the silver wires 12Ag are all rolled into a flat elliptical shape. The soft cotton wire 12CT is more easily compressed than the hard silver wire 12 Ag. In the state after the feather-proof processing, the difference in the size and the cross-sectional shape between the cotton wire 12CT and the silver wire 12Ag is small.

In the first case (FS4200AG), one silver thread is woven in for every twenty-nine weft threads. In the first example, silver threads were woven so that the silver content became 4 wt%. The cotton fabric of the first example was subjected to an antibacterial test by a bacterial suspension absorption method. The results are shown in tables 1 and 2.

The antimicrobial activity value is an index value for determining the degree of antimicrobial effect, and if the antimicrobial activity value is 2.0 or more (a mortality of 99% or more), it can be determined that the antimicrobial activity is present. The antibacterial activity values described in tables 1 and 2 were calculated from the following values: the logarithmic value of the number of bacteria after 18 hours of cultivation as a control sample without processed product divided by the number of bacteria after 18 hours of cultivation as a test sample of antibacterial processed product. Further, the antibacterial activity value of the standard cotton cloth as the comparative example was 0 (0% mortality).

Antibacterial activity value ═ log (viable cell number after culture of control sample) -log (viable cell number after just inoculation of control sample) }

- { log (number of viable bacteria after culture of test sample) -log (number of viable bacteria just after inoculation of test sample) }

As shown in table 1, in FS4200AG in which 4 wt% of silver component was woven into cotton, the antibacterial activity value of staphylococcus aureus was 2.0 or more in either 0-time washing or 10-time washing. More specifically, the antibacterial activity value of staphylococcus aureus was 6.0 (99.9999% or more mortality). As shown in table 2, in FS4200AG, the antibacterial activity value of pneumococcus was 2.0 or more in either of 0 washing and 10 washing. In more detail, the antibacterial activity value was 6.3 (mortality of 99.99995% or more).

In the second example (pezilian AG), silver wire was woven so that the silver content became 4 wt%. For reference, the silk fabric of the second example was subjected to an antibacterial test by the bacterial solution absorption method in the same manner as the cotton fabric of the first example. However, as a control sample, the same standard cotton cloth as cotton was used instead of the standard silk. Since the silk fabric was not washed repeatedly like cotton fabric, the evaluation was performed 0 times. The results are shown in tables 1 and 2.

In Petzerlike AG obtained by weaving a silk fabric with 4 wt% of silver component, the antimicrobial activity value of Staphylococcus aureus was 2.0 or more as shown in Table 1. More specifically, the antibacterial activity value was 3.5 (mortality of 99.97% or more). In addition, as shown in table 2, the antibacterial activity value of pneumococcus was 2.0 or more in pezilliform AG. More specifically, the antibacterial activity value was 2.9 (mortality of 99.9% or more).

According to the bedding 1 of the present embodiment configured as described above, the silver wires 12Ag are used for a part of the weft wires 12, and the satin weave is performed so that the floating length of the weft wires 12 is increased, so that the user can easily visually confirm the silver wires 12 Ag. The design of the bedding 1 is improved by the metallic luster unique to the silver wire 12 Ag. Further, the silver wires 12Ag are not shielded at the rear portions of the warp yarns 11, and thus the antibacterial property is improved.

The above-described embodiments are for easy understanding of the present invention, and are not intended to limit the present invention. The elements provided in the embodiments, and the arrangement, materials, conditions, shapes, sizes, and the like thereof may be appropriately changed, and are not limited to the examples. In addition, the structures shown in the different embodiments may be partially replaced or combined with each other.
