[0009] Embodiments of the present invention will be described below with reference to the drawings.

[0010] -Jersey fabric- Figure 1 is a schematic plan view showing the surface of a jersey fabric according to one embodiment of the present invention, and Figure 2 is a schematic cross-sectional view of the jersey fabric. Figure 2 corresponds to the cross-sectional view along line II-II in Figure 1. Figures 3 and 4 are magnified photographs of the surface of the jersey fabric according to one embodiment of the present invention. The photographs in Figures 3 and 4 were taken under different conditions to show the surface shape of the jersey fabric. The photograph in Figure 3 was taken in direct light to show the surface (appearance), and the photograph in Figure 4 was taken against the light to show the weave. Figure 5 is a magnified photograph of the cross-section of the jersey fabric according to one embodiment.

[0011] The jersey fabric 1 shown in Figures 1-5 is a knitted fabric made of polyester. The polyester fibers that make up the jersey fabric 1 are water-repellent fibers that have been treated with a water-repellent agent, with the surface of each individual fiber coated with a water-repellent agent. The jersey fabric 1 comprises a single-layer section 2 consisting of a single knitted fabric and a double-layer section 3 consisting of a lining 3a and a front fabric 3b. The single-layer section 2 and the double-layer section 3 are arranged periodically and repeatedly in a two-dimensional direction (vertically and horizontally) as shown in Figure 1. A single knitted fabric refers to a knitted fabric in which the front and back surfaces are not separated. For example, even if the knitted fabric itself is two layers, if the loops of the front layer and the loops of the back layer are combined or intertwined as a whole, this is called a single layer and not a double layer in this specification.

[0012] In this embodiment, the multilayer section 3 is connected in a mesh or grid pattern as shown in Figure 1, and each mesh portion of the multilayer section 3 becomes a single layer section 2. Each single layer section 2 is surrounded all around by the multilayer section 3, and is separated from adjacent single layer sections 2 by the multilayer section 3. Per unit area of ​​the jersey fabric 1, the single layer section 2 has more than half the area of ​​the multilayer section 3, and in this embodiment, the areas of the single layer section 2 and the multilayer section 3 are approximately the same. In the cross-section of Figure 2, the single layer section 2 and the multilayer section 3 are formed alternately at a pitch of several millimeters. The single layer section 2 is made of a single knitted fabric, so it has a breathable structure with mesh-like openings in the knit. In contrast, the multilayer section 3 is made of two knitted fabrics, a lining 3a and an outer fabric 3b, so it has lower breathability than the single layer section 2 but is stronger.

[0013] Furthermore, in this embodiment, the mesh sizes of the single layer 2 and the multi-layer 3 are approximately the same, but for example, the mesh size of the single layer 2 may be relatively larger, and the mesh size of the multi-layer 3 (or its outer fabric 3b) may be relatively smaller. In this case, the mesh size of the multi-layer 3 can be set within a range where the surface tension that causes water to form droplets due to the water-repellent effect of the water-repellent fibers is greater than the force that tries to draw water into the mesh due to capillary action. On the other hand, when the mesh size of the single layer 2 is relatively large, it can be set within a range where the surface tension that causes water to form droplets due to the water-repellent effect of the water-repellent fibers is less than the force that tries to draw water into the mesh due to capillary action. In other words, the mesh size of the single layer 2 may be small enough that it cannot strongly hold water droplets, for example, about 0.1-0.3 mm in size. Also, the yarn constituting the single layer 2 may have a cross-sectional area similar to that of the yarn constituting the multi-layer 3 (or its outer fabric 3b), but thinner yarn may be used than the yarn of the multi-layer 3. In this case, the stitches of the single layer 2, which is knitted with thinner yarn, can be made larger by the difference in yarn thickness compared to the stitches of the multi-layer 3, which is knitted with thicker yarn, thereby further improving breathability.

[0014] The surface (front side) of the jersey fabric 1 is an uneven surface where the multi-layered section 3 protrudes from the single-layered section 2, whereas the lining 3a of the multi-layered section 3 is flat and continuous with the single-layered section 2, so the back side of the jersey fabric 1 is flat overall. Needless to say, the jersey fabric 1 is a flexible material, and "flat" here means that when the jersey fabric 1 is placed on a flat surface such as a desk, the back side becomes flat along the flat surface. The jersey fabric 1 is knitted together with a mesh-like front fabric 3b, and the part where the single knitted fabric is knitted together with the front fabric 3b to form two layers can be considered as the multi-layered section 3, and the part where the single knitted fabric is exposed without overlapping with the front fabric 3b can be considered as the single-layered section 2. In other words, the part of the single knitted fabric that faces the front fabric 3b is the lining 3a of the multi-layered section 3, and the part of the single knitted fabric excluding the lining 3a is the single-layered section 2. In Figure 5, the single layer 2 appears thicker due to the disorder of the fibers from the cut and frayed threads, but as can be seen from Figure 4, the single layer 2 has the fabric structure shown in Figure 2. The lining 3a of the multi-layered section 3 (the flat surface of the jersey fabric 1 excluding the single layer 2) has a smaller area than the outer fabric 3b, and the difference in area causes the outer fabric 3b to bulge in a dome shape relative to the flat lining 3a.

[0015] The outer fabric 3b of the mesh-like multilayer section 3 is connected to the lining 3a at the outline of the mesh (inner circumference), but the parts between the mesh are not connected to the lining 3a, and there is a cavity 3c between the lining 3a and the outer fabric 3b. After knitting, the jersey fabric 1 is heat-treated at a temperature above the glass transition point of polyester (70°C) and below the melting point of polyester (225°C) (for example, around 120-180°C). As a result, the shape of the polyester fibers in the outer fabric 3b is stabilized in a curved shape, and the cavity 3c of the multilayer section 3 is stably maintained. There are no fillers other than air in the cavity 3c. The multilayer section 3 also plays a role in ensuring the strength of the jersey fabric 1.

[0016] -Clothing- FIG. 6 is a view showing an example of clothing made of jersey fabric according to an embodiment of the present invention. The clothing 10 shown in the figure is made of jersey fabric 1. In the figure, the clothing 10 is exemplified by sports half pants, but it is needless to say that long jersey pants or sports clothing worn on the upper body can be made of the jersey fabric 1. Further, not limited to sports clothing, the jersey fabric 1 can be applied to various types of work clothing, home clothing, nightgowns, and the like. When applying the jersey fabric 1 to clothing, it is desirable to make the uneven surface face outward so that the flat back surface touches the skin.

[0017] -Effect- (1) The jersey fabric 1 has a structure in which the mesh-like single-layer portions 2 and the multi-layer portions 3 each composed of two knitted fabrics are alternately arranged in a two-dimensional direction. Therefore, the single-layer portion 2 ensures excellent flexibility, breathability, and lightness, and the multi-layer portion 3 compensates for the strength that may be insufficient with only the thin single-layer portion 2, ensuring sufficient strength for the entire fabric. In addition, unlike a fabric structure in which a plurality of knitted fabrics are joined at their opposing surfaces to form a layer and the stitches of the plurality of knitted fabrics block each other, the multi-layer portion 3 has a structure in which the single-layer lining 3a and the surface fabric 3b are separated via the cavity portion 3c. Therefore, the lining 3a and the surface fabric 3b do not block each other's stitches, and a decrease in breathability due to being composed of a plurality of knitted fabrics is suppressed. Thus, according to the present embodiment, it is possible to provide a jersey fabric 1 that is soft, lightweight, well-ventilated, and has sufficient strength.

[0018] As a result of conducting a tensile test on the jersey fabric 1 based on the JIS L 1096 strip method, good results of warp (wale) direction = 396.0 (N) / weft (course) direction = 313.0 (N) were obtained (reference value: warp = 200 (N) / weft = 200 (N)). Also, in a tear test based on the JIS L 1096 pendulum method, good results of warp (wale) direction = 45.9 (N) or more / weft (course) direction = 55.7 (N) were obtained (reference value: thin fabric = 7 (N) / thick fabric = 10 (N)).

[0019] (2) Since the multilayer part 3 has a two-layer structure of the lining 3a and the surface fabric 3b, it is difficult to see through. Because such a multilayer part 3 exists as a whole, the jersey fabric 1 also has the merit of being difficult to see through. In the evaluation of the ultraviolet ray shielding rate based on JIS L 1925, a good result with a shielding rate of 95.6% for wavelengths of 290 to 400 nm was obtained.

[0020] (3) In general, soft knitted fabrics are prone to forming lint balls. However, for the jersey fabric 1 of the present embodiment, by separately treating polyester, in addition to the effect of stabilizing the shape of the cavity part 3c, the effect of being difficult to form lint balls can also be obtained. In the evaluation of pilling based on the JIS L 1076A method, a good result of grade 5 was obtained.

[0021] (4) For example, a general jersey used as sportswear is made of a flat fabric and cannot express patterns without using colors. In contrast, for the clothing 10 of the present embodiment, since the uneven surface of the jersey fabric 1 itself forms a pattern, it has a unique aesthetic property.
