Description

  The present invention relates to a functional three-dimensional net knitted fabric sheet in which a spherical body exhibiting various functions is loaded in an internal space of a three-dimensional net knitted fabric sheet knitted with double raschel knitting.

  Conventionally, a three-dimensional net knitted fabric by double raschel knitting has been provided. This material is a monofilament connecting yarn that connects the front and back knitted fabrics made from polyester or nylon spun multifilament yarns into a net fabric structure and connects them so as to maintain a predetermined thickness interval. As a result, the nets on the front and back sides have a unique appearance as if they floated together with frost columns. It is extremely tough, superior in cushioning, body pressure dispersibility, drainage and breathability, and is a technically advanced fiber product. However, since the material characteristics are extremely different from the general characteristics required for fiber products, they are difficult to use in general applications despite being advanced fiber products.

Japanese Patent No. 2720985 JP 2001-89959 A Focusing on the toughness, cushioning properties, body pressure dispersibility, and breathability of three-dimensional net knitted fabrics, three-dimensional solid sheets suitable for chair cushion materials and chair cushion cushions Proposals have already been made (see Patent Document 1 and Patent Document 2). However, the spread of products using a three-dimensional net knitted fabric is low as a whole.

  The present invention has been made from the viewpoint of developing a novel sheet-like material by utilizing the unique characteristics of the above-described three-dimensional net knitted fabric, and is conscious of overcoming the drawbacks and problems of existing products. Not. The point of focus during development is the air gap that exists between the front knitted fabric and the back knitted fabric. That is, it is considered that the three-dimensional net knitted fabric can be applied to various uses by loading the voids with various compositions exhibiting a certain function.

  Therefore, the problem to be solved by the present invention is how to stably load what composition is in what form and in what way into the void of the three-dimensional net fabric. Specifically, a monofilament-like object cannot be loaded between the front knitted fabric and the back knitted fabric of the three-dimensional net knitted fabric because monofilament connecting yarns come and go like frost columns. A method of pouring a bead-like object from the cut end face of the three-dimensional net knitted fabric by free movement and binding the end face has also been attempted, but in this case, the deviation of the bead-like object cannot be controlled. The present invention is proposed to solve these problems and other incidental problems.

  The present invention adopts the following configuration as means for solving the above-mentioned problems.

  The functional three-dimensional net knitted fabric sheet according to claim 1 of the present invention is a surface knitted fabric obtained by knitting a multifilament yarn into a net fabric having coarse hexagonal net holes and a multifilament yarn having fine hexagonal net holes. A back knitted fabric knitted into a net fabric having a knitted fabric is connected at a predetermined thickness interval with a connecting yarn made of monofilament yarn knitted so as to travel between the front knitted fabric and the back knitted fabric. A large number of functional spherical bodies are loaded in the thickness interval of the three-dimensional net knitted fabric made by double raschel knitting. At this time, the functional spherical bodies pass through the hexagonal net holes of the front knitted fabric. It is shaped to a possible diameter and is tightly loaded through hexagonal net holes in the surface knitted fabric.

  Since the front knitted fabric and the back knitted fabric of the three-dimensional net knitted fabric having the above-described configuration are both formed by knitting multifilament yarns into a net fabric, great stretchability can be exhibited. That is, the hexagonal net holes of the front knitted fabric and the back knitted fabric can be forcibly opened by an external force. Here, the hexagonal net hole of the front knitted fabric is intentionally rough with respect to the hexagonal net hole of the back knitted fabric. Therefore, the three-dimensional net knitting is performed via the hexagonal net hole of the front knitted fabric which is coarse. The functional spherical body closely packed within the thickness interval of the ground cannot escape from the hexagonal net hole of the back knitted fabric which is fine. That is, the three-dimensional net knitted fabric is used as a carrier that holds a functional spherical body at a specific position. The functional spherical body may be loaded in all hexagonal net holes of the surface knitted fabric, or may be loaded only in some hexagonal net holes. Since the spherical body does not have directionality, it can be loaded without selecting the directionality, and the solid net knitted fabric in which the spherical body is neatly loaded exhibits a unique feel that the skin is massaged. . Therefore, it can be applied not only to the functional use of a spherical body but also to a use utilizing this touch. The composition and function of the spherical body are not particularly limited, and it is sufficient that the spherical body has a diameter that can be loaded through the hexagonal net hole of the surface knitted fabric.

  The functional three-dimensional net fabric sheet according to claim 2 of the present invention is loaded with a mixture of a plurality of types of spherical bodies having different functions within the thickness interval between the front knitted fabric and the back knitted fabric. It is characterized by.

  The functional three-dimensional net knitted fabric sheet having the above configuration is complex or synergistic unless the functions of two or more kinds of spherical bodies to be loaded are functions that cancel each other such as fragrance and deodorant. Therefore, it is possible to adapt to a wider range of applications by combining the functions.

  The functional three-dimensional net fabric sheet according to claim 3 of the present invention is characterized in that a spherical body to be loaded is a spherical molded product of a composition having ceramics having far infrared radiation as a main functional component. .

It is extremely comfortable when used as a mattress.

  The functional three-dimensional net knitted fabric sheet according to claim 4 of the present invention is characterized in that the spherical body to be loaded is a spherical molded product of a composition containing a ceramic having negative ion radioactivity as a main functional component. .

  The functional three-dimensional net knitted fabric sheet having the above-described configuration can exhibit an effect of deactivating the activity of odorous substances by a negative ion generated from a spherical body and a specific relaxation effect. It can be suitably used for a floor covering of a toilet floor, a backrest of a vehicle seat, a chair floor, and the like.

  The functional three-dimensional net fabric sheet according to claim 5 of the present invention is characterized in that a spherical body to be loaded is a spherical molded product of a composition containing a fragrance material having a fragrance releasing ability as a main functional component. To do.

  In the above configuration, it is preferable to use a natural aroma substance extracted from a natural plant as the aromatic material constituting the spherical body. For example, extracted essential oil components such as hinokitiol, vanilla, lavender, rose, rush, bamboo, bamboo grass, black moji, camphor tree and the like. Suitable for use on pillow covers, etc.

  The functional three-dimensional net fabric sheet according to claim 6 of the present invention is characterized in that a spherical body to be loaded is a spherical molded product of a composition containing a carbide having moisture conditioning ability as a main functional component.

  The functional three-dimensional net fabric sheet according to claim 7 of the present invention is characterized in that a spherical body to be loaded is a spherical molded product of a porous composition having an elastic recovery ability.

  In the functional three-dimensional net fabric sheet having the above-described configuration, the porous composition having elastic recovery ability refers to foamed rubber, a low-rebound or high-rebound sponge, and the like. Since the body pressure dispersibility can be adjusted by adjusting the elastic force of the spherical body to be loaded, it can be applied to various uses such as a cushion cover, a bed underlay and an overlay. Further, since the spherical body is deformed, the user can easily desorb the spherical body and use it as a personally preferable state.

  The functional three-dimensional net knitted fabric sheet of the present invention has coarse hexagonal net holes in the front knitted fabric knitted into the net fabric, and finely sets the hexagonal net holes in the back knitted fabric knitted into the net fabric. The hexagonal net of the front knitted fabric is made of various functional spherical bodies that are formed to have a diameter that allows the hexagonal net hole of the front knitted fabric to be expanded by passing through the thickness interval between the front knitted fabric and the back knitted fabric. By tightly loading through the holes, a sheet-like body holding a spherical body that can be optionally selected by a three-dimensional net knitted fabric can be formed, so it can be widely applied to various applications that match the function of the spherical body There is an effect that can be done.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The functional three-dimensional net fabric sheet 50 according to the present invention is composed of a large number of functional spherical bodies 35 and three-dimensional net fabric 20 (FIGS. 1 and 2).

  The three-dimensional net knitted fabric 20 is a net structure having a special structure knitted by a dedicated double raschel knitting machine, and is usually also referred to as “three-dimensional solid net”, “three-dimensional sheet”, “three-dimensional knitted fabric”, etc. It is for commercial use. The three-dimensional net knitted fabric 20 includes a front knitted fabric 21 and a back knitted fabric 22 each having a hexagonal net hole, and a connecting yarn 23 that is knitted so as to travel between the two. The connecting yarn 23 is connected to the front knitted fabric 21 and the back knitted fabric 22 while maintaining a predetermined thickness interval D1, and the three-dimensional net knitted fabric 20 is imparted with a cushioning property corresponding to the thickness interval by its deformability. The size of the hexagonal net hole 21H of the front knitted fabric 21, the size of the hexagonal net hole 22H of the back knitted fabric 22, and the thickness interval D1 can be individually changed by setting of the double raschel knitting machine.

  The fiber material usually used in the three-dimensional net knitted fabric 20 is nylon or polyester. In addition, the front knitted fabric 21 and the back knitted fabric 22 are made of multifilament yarns that are crimped to strength, and the connecting yarns 23 are made of monofilament yarns having a thick round cross section. As a result, the constituent yarn 21S constituting the front knitted fabric 21 and the back knitted fabric 22 can be extended to about 150% of the unit length L1 by a tensile external force (FIG. 3).

  In the three-dimensional net fabric 20 of the present invention, the hexagonal net holes 21 of the front knitted fabric 21 are coarse, the hexagonal net holes 22H of the back knitted fabric 22 are relatively fine, and the front knitted fabric 21 and the back A three-dimensional net knitted fabric 20 in which the thickness interval D1 between the knitted fabrics 22 is set to be equivalent to the diameter D2 of the functional spherical body 35 is used. Further, the size of the hexagonal net hole 21H of the front knitted fabric 21 and the diameter D2 of the spherical body 35 are such that the spherical body 35 can pass through the hexagonal net hole 21H by an artificial external force. After passing, the hexagonal net hole 21H is sized so as to fit within the diameter D2 of the spherical body 35 (FIG. 4).

  The spherical body 35 that can be used for the functional three-dimensional net knitted fabric sheet 50 of the present embodiment is extremely diverse. What is used in this embodiment is a general porcelain material to which a fine powder of silica is added. As the porcelain material and the fired fine powder of silica, commercially available ones are sufficient. However, it is preferable to use the fine powder of silica that has been provided for use in generating negative ions and far infrared rays. Since the porcelain material is usually provided in a clay plate state, it is cut into an appropriate size, and about 20% by weight of silica fine powder is added and sufficiently kneaded with water until uniform.

  The water-kneaded composition is pressure-dehydrated to a moisture content appropriate for granulation, applied to a granulator, and prepared to have a diameter D2 required in relation to the hexagonal net hole 21H. The composition granulated to a predetermined diameter D2 is naturally dried, and is subjected to primary baking at 800 to 900 degrees for about 20 minutes. Depending on the application of the three-dimensional net knitted fabric sheet 50, the composition that has undergone the primary firing can be used as it is as the spherical body 35 for the present invention. However, since the spherical body 35 in this state is in an unglazed state and has a rough surface, in order to improve the touch, a small amount of glaze is applied to the primary baked one, and this is applied at a temperature of 900 to 1000 degrees. By performing the main baking for about 120 minutes to 120 minutes, the spherical body 35 having an appropriate touch can be obtained. In addition, it is preferable to add about 20% by weight of silica to the glaze used at this time in order to secure the generation amount of negative ions and far infrared rays.

  The three-dimensional net knitted fabric 20 is cut into a use size for each application, and edge processing 25 is performed (FIG. 1). The completed spherical body 35 is pushed into the hexagonal net hole 21H from the front knitted fabric 21 side of the three-dimensional net knitted fabric 20. The spherical body 35 loaded in the thickness interval D1 of the three-dimensional net knitted fabric 20 through the hexagonal net hole 21H is restrained and held at the position by the front knitted fabric 21, the back knitted fabric 22 and the connecting yarn 23 ( FIG. 5). Although this operation is a manual operation at the present time, since the operation is not difficult, the operation of loading the spherical body 35 does not take time unexpectedly. However, rationalization of work such as winding the three-dimensional net fabric 20 around a roll and rolling on the spherical body 35 is under consideration.

  The functional three-dimensional net knitted fabric sheet 50 of this form can enjoy a peculiar touch with a negative ion bath, a far-infrared bath, and a massage feeling, for example, by laying it at the bottom of a bathtub. Although the spherical body 35 of this form is a hard substance, since each spherical body 35 is in the state mounted on the back knitted fabric 22 of the three-dimensional net knitted fabric 20, it does not contact a bathtub directly, but a bathtub. There are no inconveniences to hurt. Since the drainage is good, after use, it is possible to maintain a sanitary condition simply by putting shower water on the side of the bathtub. The functional three-dimensional net knitted fabric sheet 50 in this form has a deodorizing action of odorous substances due to negative ions, and therefore shows suitability as an underlay.

  The spherical body 35 is not limited to a hard material, and for example, a porous composition having elastic recovery ability such as foamed rubber or sponge can be used. The cushioning property in the case of only the three-dimensional net knitted fabric 20 depends solely on the connecting yarn 23, but the cushioning property can be freely adjusted by loading the three-dimensional net knitted fabric 20 with an elastic spherical body 35. A suitable personality can be imparted by backing or placing a seat of a chair or a vehicle. In this application, it is also a great advantage that the loading position and loading amount of the spherical body 35 can be changed according to personal preference.

  The functional three-dimensional net fabric sheet 50 of the present invention is also characterized in that a plurality of types of spherical bodies having different functions can be mixed and loaded on the three-dimensional net fabric 20. For example, even when used for a seat of a vehicle, it is easy to use such as loading a hard spherical body 35 at a position where a massage effect is desired and loading an elastic spherical body 35 at a position where a cushion effect is desired. Is realized.

  In addition, although the kind of the spherical body 35 which can be utilized for the functional three-dimensional net fabric sheet 50 of this invention is various as mentioned above, it cannot be said that manufacturing these all by itself is reasonable. The glass sphere 35 is from a toy marble supplier, the wooden sphere 35 is from a wood bead supplier, and the elastic sphere 35 is from a sponge ball manufacturer from a carbide sphere 35. Can be obtained from fuel suppliers, and can contribute to various industrial fields.
