Detailed Description

Hereinafter, a blanket according to an embodiment of the present invention will be described in detail with reference to the drawings.

It should be noted that, in the drawings, the sizes of the components are not consistent with the actual sizes, and the components need to be considered with reference to the actual cases.

Blanket

As shown in fig. 1, the carpet 1 has a substantially rectangular shape, has a longitudinal direction L and a width direction W, and has rounded corners formed at four corners. However, the blanket 1 of the present invention may have other shapes than a rectangular shape, for example, various shapes such as a circle, a triangle, and a diamond. In addition, the blanket 1 of the present invention may not have a round corner.

As shown in fig. 1, the carpet 1 has a carpet main body 2 and a hem member 3 sewn along a peripheral portion of the carpet main body 2. However, the carpet 1 of the present invention may not have the edge covering member 3, and may have only the carpet body 2.

The size of the edge covering member 3 can be arbitrarily selected according to actual requirements. For example, the area of the edge covering member 3 may be 5% or more of the entire area of the carpet body 2.

The blanket body 2 may be formed of a woven fabric in which warp yarns and weft yarns are alternately woven, and the weight per unit area of the blanket body 2 may be set to 160 to 250g/m². The weight per unit area of the blanket body 2 is set to 160g/m²As described above, the blanket body 2 has a weight per unit area of 250g/m, which improves the heat retention property²The weight reduction and antibacterial properties are improved as follows.

The specific weave pattern of the warp and weft yarns may be chosen arbitrarily according to practical requirements. For example, as shown in fig. 1, the warp yarns and the weft yarns may be alternately woven in units of one warp yarn and one weft yarn, respectively. Further, the warp yarns and the weft yarns may be alternately woven in units of a plurality of warp yarns and a plurality of weft yarns, respectively, and the number of warp yarns and the number of weft yarns may be the same or different. In addition, various patterns designed in advance can be woven by using the warp yarns and the weft yarns through computer control.

The carpet body 2 may have a warp density of 8 to 16 warps/cm and a weft density of 8 to 16 wefts/cm. The warp density of the warp yarns and the weft density of the weft yarns may be the same or different. The ratio of warp yarn density to weft yarn density may be set to 1: 0.8 to 1.2. In addition, the ratio of the warp yarn density to the weft yarn density may be further set to 1: 1 to 1.2.

The warp density refers to the number of warp yarns arranged in a unit length of the felt body, and the weft density refers to the number of weft yarns arranged in a unit length of the felt body.

In addition, the warp yarns can be formed by the modacrylic yarns with the counts of 8-16 s, and the weft yarns can be formed by the modacrylic yarns with the counts of 8-16 s. The number of modacrylic yarns forming the warp yarns may be the same as or different from the number of modacrylic yarns forming the weft yarns. The carpet is improved in lightweight property and antibacterial property by setting the count of the modacrylic yarn constituting the warp and the weft to 8s or more. The felt has improved heat retention properties by setting the count of the modacrylic yarn constituting the warp and the weft to 16s or less.

Wherein the count of 1s represents the thickness of 453 g of yarn at 768 m. The larger the count, the thinner the yarn. For example, the count of a 453 g yarn at 1536 m is 2 s.

As described above, the carpet body 2 may be made of a fabric woven from modacrylic yarn. For example, modacrylic may be used in an amount of 90% by weight or more of the blanket body 2. The covering member 3 may be a fabric woven from modacrylic yarn, as in the felt body 2. For example, modacrylic may be used in an amount of 90% by weight or more of the covering member 3. The number of modacrylic yarns constituting the covering member 3 may be set to 8 to 16 seconds. The weight per unit area of the edge covering member 3 may be set to 320 to 750g/m²。

In general, the production process of a felt includes various steps such as raw cotton, spinning, knitting, and drying.

The felt 1 of the present embodiment can use, as raw cotton, modacrylic having a fineness of 1.5 to 3.3dtex (for example, 1.7dtex or 3.3 dtex). The modacrylic raw cotton tends to have a fineness of 1.5dtex or more, and thus has good spinning processability. By setting the fineness of modacrylic raw cotton to 3.3dtex or less, the warmth retention property, strength and antibacterial property of the blanket tend to be better.

Effect of action

The utility model discloses a woollen blanket can compromise lightweight nature, warmth retention, bacterinertness and fire resistance through the structure that has above-mentioned first technical scheme.

The utility model discloses in, what adopt is thinner lighter machine weaving woollen blanket, compare with raschel woollen blanket, can compromise lightweight and warmth retention. Further, the warp and weft are constituted by the modacrylic yarn, so that lightness, warmth retention, antibacterial property, and flame retardancy can be simultaneously ensured. Further, since the woven blanket has no standing hair and can suppress depilation as compared with a raschel blanket, the possibility that the depilation hair is attached to the user is reduced, which is preferable from the viewpoint of reducing unpleasant feeling and burden on the user.

In addition, in the present invention, the number of modacrylic yarns constituting the warp and weft is set to 8 to 16 s. The blanket body 2 has a weight per unit area of 160 to 250g/m². The fineness of the raw cotton was 1.5 to 3.3 dtex. This can achieve a balance between lightweight properties, heat retention properties, antibacterial properties, and flame retardancy.

Furthermore, in the present invention, the warp density is set to 8 to 16 pieces/cm, and the weft density is set to 8 to 16 pieces/cm. The ratio of warp density to weft density was set to 1: 0.8 to 1.2. This can more reliably achieve a balance between lightweight properties, heat retention properties, antibacterial properties, and flame retardancy. In addition, the ratio of the warp yarn density to the weft yarn density is preferably further set to 1: 1 to 1.2. This can further reliably achieve a balance between lightweight properties, heat retention properties, antibacterial properties, and flame retardancy.

Examples

Example 1

5 blankets shown in FIG. 1 (modacrylic fiber 100%; blanket body having a basis weight of 200 g/m) were prepared²(ii) a The number of the warp yarns and the weft yarns is 10 s; warp and weft densities of 12 threads/cm) as an example of the invention.

The results of the evaluation of the antibacterial property, the lightweight property, and the heat retention property by the methods described later on for the felt of the present example were that the felt had an excellent balance of properties as compared with the felt used in the comparative example.

Comparative example 1

The felt was produced in the same manner as in the examples, except that the raschel felt (meyer felt) formed of modacrylic fiber was used instead of the woven felt. The lightness of the blanket is inferior to that of the embodiment. In addition, usability (easy to fall down, attached to clothes and face) including durability is also poor.

Comparative example 2

Except that the warp and weft constituting the felt main body use warp with count of 5sThe felt was produced in the same manner as in the examples except for the yarns and the weft yarns. The blanket body of the blanket has a weight per unit area of more than 250g/m². The carpet is less lightweight and less antibacterial than the embodiment carpet.

Comparative example 3

A felt was produced in the same manner as in the examples, except that warp yarns and weft yarns having a count of 20s were used as the warp yarns and weft yarns constituting the felt main body. The blanket body of the blanket has a weight per unit area of less than 160g/m². The blanket had inferior warmth retention compared to the blanket of the example.

Comparative example 4

A felt was produced in the same manner as in the examples, except that the densities of the warp and weft constituting the felt main body were set to 6 yarns/cm, respectively. The blanket had inferior warmth retention compared to the blanket of the example.

Comparative example 5

A felt was produced in the same manner as in the examples, except that polyester fibers were used for the warp and weft constituting the felt main body. Compared with the blanket of the embodiment, the blanket has obviously poorer antibacterial property and poorer heat retention property.

Method for evaluating blanket

The blankets of each example and comparative example were placed 5 each in the economy class of the aircraft at the same time for use by passengers. The used carpets were collected and placed in the same room, and the time required for odor generation or odor generated within a certain period of time were recorded, and the average value was recorded for each carpet, thereby evaluating the antibacterial properties of each carpet.

In addition, regarding the warmth retention property and the lightweight property, sensory evaluation was performed for each of the blankets by touching ten users with hands, and the average value of the evaluation results was calculated to perform the evaluation.

As a result, the carpet of the present embodiment was found to have significantly improved antibacterial properties, heat retention properties and lightweight properties, as compared with the comparative examples. Further, since the felt body is made of modacrylic yarn, the felt of the present example is excellent in flame retardancy.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
