Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a knitted fabric having protrusions that are applied to tights, girdles, socks, supporters, and the like to produce an effective massage action, anti-skid action, and the like.
[0002]
[Prior art]
Conventionally, as this type of knitted fabric, Japanese Patent Application Laid-Open No. 11-152607 discloses a tuck stitch mesh as shown in FIG. 8, in which a conventional knitting yarn and a stretchable yarn are combined three-dimensionally and alternately. A girdle D in which a concave waveform 21 and a convex waveform 22 are formed has been proposed.
[0003]
However, the tuck stitch mesh, i.e., the tuck knitted structure, has a drawback that the stretchability is reduced as the ground thickness is increased, and a plurality of types of yarns including a conventional knitting yarn and a stretchable yarn, that is, a polyurethane elastic yarn must be prepared. Multi-threaded single-cylinder knitting machine that is complicated and has an uneven pattern that is limited to a corrugated pattern, that is, a chevron weave of woven fabric, and has little change. However, there are problems such as high costs due to necessary conditions.
[0004]
In registered utility model No. 3058883, a sock is proposed in which a pattern knitting structure having an uneven pattern is formed on the sole portion.
[0005]
However, various pattern structures are presented as the pattern knitting structure. However, since it is a complicated pattern knitting structure, an expensive double cylinder knitting machine is required, resulting in high costs and formation of large unevenness. Since this is not possible, there is a problem that the effect is limited.
[0006]
Registered Utility Model No. 30613334 proposes a sock in which a double-cylinder knitting machine is used to form a deer-shaped concavo-convex pattern on the sole by a knitting structure.
[0007]
However, Lynx knitting is a knitting structure that looks like an uneven pattern on the exterior, and has poor effects such as massage and anti-slip action, and the needle selector for lynx patterns that creates patterns alternately on both the front and back surfaces There is a problem that an expensive double cylinder knitting machine equipped with is required and the cost is increased.
[0008]
[Problems to be solved by the invention]
Therefore, the object of the present invention is to provide a projection with a completely new and simple knitting structure using an inexpensive single cylinder knitting machine, and to reduce the cost, and to determine the shape, size, arrangement, etc. of the projection. It is possible to select freely, and to provide a knitted fabric having projections on the back surface in contact with the skin and having a large massage action, anti-slip action, and the like.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, during weft knitting, 3 to 7 knitting needles are placed in a non-operating position so as to skip one knitting needle, and 5 to 30 courses are gradually reduced from the center to both sides. Then, after knitting, the knitting yarn at the non-operating position is contracted to form stitches adjacent to the core to form planar substantially circular or oval shaped projections having a wide projection surface, and the projections are formed on the back surface of the knitted fabric. They were separated from each other and evenly distributed .
[0010]
Further, the protrusions zigzag pattern like or arranged alternately may be provided in a checkered pattern.
[0011]
[Action]
The knitted fabric according to the present invention is knitted using a single cylinder knitting machine, and the whole is a flat knitted fabric and has a large stretchability and adheres well to the body, and also has a massaging action because the protrusion is present on the back side of the knitted fabric, Uneven effect such as non-slip action is large.
[0012]
Further, the structure of the protrusion is simple, the number of knitting needles and the number of inactive courses at the inactive position can be freely selected, and there is an advantage that the shape, size, and arrangement pattern of the protrusion can be changed as appropriate. . When the protrusions are arranged in a staggered pattern or checkered pattern, the concave and convex portions are alternately dispersed to increase the unevenness effect, and the durability against external force is improved.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0014]
FIG. 1 shows tights A formed with a knitted fabric of the present invention, and an electronic device capable of freely knitting a desired stitch structure by using a knitted yarn made of bulky processed filament such as nylon, cotton yarn, polyurethane elastic yarn, etc. A panty part 2 in which the entire body knitted from a controlled single cylinder circular knitting machine is of a flat knitted structure and is joined to the left and right bodies at the crotch center suture line 1 and below the panty part. It consists of a pair of left and right leg portions 3, 3. A waist band 4 is provided on the upper edge of the panty portion 2, and edge portions 5, 5 are provided on the lower edge of each leg portion 3, 3.
[0015]
Said body locations tights A is 2, 3, 4 and 5, in the weft knitting plain knitted fabric knitting, the knitting needles N ₁ of five, N _2, N _3, N _4, N ₅ is in the inoperative position, the knitting needles N ₁ and N _{5 at} both ends are knitted for 14 courses, the knitting needles N ₂ and N ₄ are for 16 courses, and the central knitting needle N ₃ is for 18 courses. A loop is not formed, and after knitting, the _two adjacent knitting yarns Y ₁ , Y ₂ , Y ₃ , Y ₄ , and Y ₅ at the inoperative position shrink the stitch adjacent to the core and the knitted fabric back surface 6 (FIG. 4). And a flat substantially oval projection 7 is formed in each case.
[0016]
The knitting needles at the inactive position are selected so as to skip one knitting needle, and chain stitches 8, 8, 8, 8 are formed between the knitting needles at the inactive position by the knitting needles of the normal action. In addition, the number of knitting needles in the inactive position is 1 to 10, preferably about 3 to 7.
[0017]
The protrusions 7, as shown in FIG. 3, is formed a number of inoperative course flat, substantially oval shape is gradually decreased from the center to both sides direction, a little away alternately knitted entirely provided in a staggered pattern like Since the projection surfaces are wide and alternately arranged, the pressing effect such as a massage action is large.
[0018]
In addition to knitting the projecting portion 7 into a substantially oval shape, a shape such as a substantially circular shape, a substantially rectangular shape, a substantially cross-beam shape, or a substantially triangular shape can be appropriately selected according to the application. the size of the protruding portion by changing the number of courses of knitting needles placed at the operating position, although Ru may be appropriately selected height, etc., as shown in FIGS. 3, 4 and 6, the size of the protrusions Are substantially the same size and are preferably evenly distributed.
[0019]
In the tights A, as shown in FIGS. 4 and 5, the protrusion 7 is formed on the back surface 6 so that the protruding portion 7 is formed in the inoperative position. For example, the knitting needle N ₅ closes the knitting yarn Y ₅ . This is because the escape from the old loop is stopped in the direction of the surface 9 while being held by the sword, and the adjacent moving knitting needle moves up and down while knitting the new loop sequentially into the old loop. After the predetermined number of courses are stopped, the knitting needle N ₅ is activated to form a loop and to be connected to the adjacent loop group. As described above, since the protruding portion 7 protrudes from the back face 6 that is in direct contact with the skin, there is an advantage that the pressing effect such as a massage action becomes particularly large.
[0020]
FIG. 6 shows a knitted fabric of another embodiment of the present invention, that is, a sock B, which is knitted by a single cylinder round sock knitting machine, and specific four knitting needles are knitted to the sole 10 during the knitting of the knitted fabric. Knitting about 15 courses, and the stitches adjacent to the core of the knitted yarn in the non-acting position after knitting contracted, and the substantially rectangular protrusions 12 approached alternately on the back side 11 of the knitted fabric, i.e., the inner surface. Is provided.
[0021]
In the socks B, when the protrusions 12 are alternately approached and the knitted fabric is thick, the yarns of the protrusions 12 are relatively tightly tightened, and the top surface of the protrusions is lateral, that is, the course direction. Since the knitting yarns Y are arranged in this manner, a large massage action and non-slip action occur when worn.
[0022]
In addition, the socks B can be provided on only the sole portion as described above, and can also be provided on the leg portion or the like according to the application.
[0023]
FIG. 7 shows a knitted fabric according to still another embodiment of the present invention, that is, a medical supporter C, which is knitted by a single cylinder circular knitting machine and is formed of a knitting yarn mainly composed of acrylic having heat retention and flexibility. The knitted fabric is knitted on the entire circumference and knitted for about 10 courses with the specific five knitting needles in the inactive position, and the horizontally long substantially oval projections 13 are provided in a zigzag pattern on the back surface. The rubber bands 14 and 14 are formed at both ends of the cylindrical body.
[0024]
The supporter C is a flat knitted fabric with a large stretch, and each protrusion is dispersed. The supporter C is soft and comfortable when worn on the legs and arms. The protrusion bulges on the inner surface to massage the affected area. In addition to providing a heat retaining action and the like, there are recesses between the projecting portions, and there are effects such as air permeability and difficulty in stuffiness.
[0025]
The knitted fabric according to the present invention is useful when applied to girdle, various supporters, shape-up pants, nursing underwear, sports socks, etc., in addition to the tights, socks, and supporters of the above embodiment.
[0026]
【The invention's effect】
According to the present invention, as described above, the protrusion can be knitted by a simple knitting structure by an inexpensive single cylinder knitting machine, and can be provided at a low cost. The effect of massage, anti-slip, etc. is particularly great because of its large nature and close contact with the body, as well as the bulge of the protrusion on the back of the knitted fabric.
[0027]
In addition, the protrusions can be easily selected in shape, size, height, arrangement pattern, etc., and provided in a staggered pattern or checkered pattern in which the protrusions are alternately arranged on the knitted ground, For example, in the case of the bottom of a sock, the external force applied to the protrusions is evenly distributed, the protrusions are difficult to flatten, the unevenness effect can be maintained over a long period of time, and the concave protrusions are evenly distributed, so that it is breathable and stuffy Hateful.
