Technical field

TECHNICAL FIELD [0001] The present invention relates to a three-dimensional warp knitted fabric excellent in tactile sensation and air permeability, which is formed by inserting and locking insertion threads exposed on the outer surface and inner surface of a ground structure of a three-dimensional warp knitted fabric made of fibers. . Background art

[0002] Three-dimensional knitted fabrics composed of front and back ground structures and connecting yarns connecting them, especially three-dimensional warp knitted fabrics knitted by warp knitting, are widely used due to their excellent resilience, cushioning, breathability, etc. Has been used over. In the apparel field, it is used as general apparel, sports apparel, and inner apparel. In the interior material field, it is widely used as a skin material for automobile seats, chairs, beds, and cushion materials. Furthermore, by providing unevenness on the surface of this three-dimensional knitted fabric, it is possible to reduce the area in contact with the skin and improve the air permeability and the touch.

[0003] Several methods have been proposed for reducing the area in contact with the skin in a three-dimensional knitted fabric such as a three-dimensional warp knitted fabric. For example, Patent Document 1 applies a high-pressure liquid flow to a woven or knitted fabric, It is disclosed to form a stripe pattern. Patent Document 2 discloses that a pattern is formed on the surface by heating and pressing a knitted fabric with a calendar roll or the like.

[0004] However, in the case of a ridge formation method using a high-pressure liquid flow, it is difficult to maintain the ridge shape on the surface of the knitted fabric for a long period of time. There is a risk that the texture may deteriorate due to hardening.

[0005] Further, there is known a method of forming irregularities on the surface with a knitted structure that is not based on such post-processing. For example, Patent Document 3 discloses a method of forming a concavo-convex structure on the surface of a knitted fabric using a mesh knitting, a needle-punched structure, or a tuck knitting. Patent Document 4 proposed by the present inventors discloses a method for forming irregularities by using two yarns having different thicknesses when knitting a knitted fabric and adjusting the swing width of the yarns. There is. In Patent Document 5, two or more types of distances (intervals) between the front and back fabric structures to be connected are adjusted by adjusting the runner value of the connecting yarn. A method is disclosed in which unevenness is formed on the surface by changing to the above.

[0006] However, in the method of Patent Document 3, irregularities are formed by pinching the ground structure with ground yarn, so that the ground texture becomes hard and the texture becomes poor. In the method of Patent Document 4, the needle loop of the ground structure is formed with a thick thread and a thin thread, and the unevenness is formed by forming the thread with a thread. As a result, the texture may become worse due to the harsh feel and may cause discomfort.

[0007] In addition, in the methods of Patent Documents 3 and 4, since the length of the thread such as a loop exposed on the surface is short, the air permeability is good. There was a problem that the texture was hardened even when using.

[0008] In addition, as a prior art for improving the tactile sensation of the surface, there is a technique of raising the surface, but there is a problem that the number of processing steps increases. In addition, there are problems such as jumping out of the connecting yarn caused by raising the surface and lowering the strength of the ground structure.

[0009] In addition, in the case of a ground tissue cache structure, there is a problem that the tactile feeling of the mesh opening force is also deteriorated due to the connecting yarn popping out.

[0010] Further, according to the method of Patent Document 5, the concave portion obtained by adjusting the connecting yarn does not have the effect of the concave and convex portions, and the ground structure is hardened by the loop of the ground texture being pulled by the connecting yarn in the concave portion. There was a problem.

[0018] Furthermore, it is possible to provide a three-dimensional structure that eliminates the insertion thread protruding from the ground structure surface, hardening of the ground texture surface, roughness, and the like.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described.

[0020] As a result of diligent research to solve the above-mentioned problems, the present inventors have found that in a three-dimensional structure warp knitted fabric in which two ground structures on the front and back sides and the both ground structures are connected with connecting yarns, As schematically shown in Fig. 1, at least one of the front and back fabrics 1, 2 is inserted into the outer fabric 1 of the ground fabric 1 Inserting and locking to be exposed to the In particular, the above-mentioned problem can be solved by inserting and locking the insertion thread 4 in the wel direction without forming a stitch (loop formation) between the loops la and la forming the ground texture 1. I found out.

[0021] In the present invention, the insertion locking of the insertion thread to the ground structure is, as shown in Fig. 1, at least one of the ground structures 1, 2 on the front and back sides, for example, the loop la forming the surface texture 1 The insertion thread 4 is inserted into the surface structure 1 by moving without insertion of a loop basically between the loop la from the outer surface to the inner surface side and from the inner surface to the outer surface side. The state of being locked.

[0022] In the figure, reference numeral 1 indicates a surface texture, reference numeral 2 indicates a lining texture, and la and 2a indicate loops of stitches that form the ground texture, respectively. Reference numeral 3 is a connecting thread for connecting the ground structures 1 and 2, reference numeral 4 is an insertion thread, reference numeral 4a is an exposed insertion thread located on the outer surface side of the ground texture, and 4b is a ground thread. The insertion thread portion exposed on the inner surface is shown.

[0023] As shown in Fig. 1, the insertion thread 4 is located on the outer surface of the surface yarn and weave 1 and the insertion thread portion 4a is exposed, and the insertion thread 4 is exposed on the inner surface. The ratio (exposure ratio) of the number of courses of each exposed portion of the yarn portion 4b is preferably 1: 1 to 1: 8, and more preferably 1: 2 to 1: 6. If the exposed ratio of the insertion thread between the outer surface and the inner surface of the ground structure is less than 1: 8 (1Z8), the tactile sensation may be impaired, and if it is larger than 1: 1 (1Z1), the tactile sensation will be worsened and further insertion will occur. There is a possibility that the yarn is easily pulled.

[0024] The number ratio SR of the insertion yarn in the course direction (knitting width direction) on the outer surface of the ground structure in which the insertion yarn is inserted and locked is 10 to 40%, and further 10 to 20%. It is preferable. If the ratio of the number of the insertion yarns is less than 10%, excellent surface touch and air permeability may not be obtained !, and if it is larger than 40%, the texture may become hard.

[0025] The number ratio SR (%) of inserted yarns in the course direction on the outer surface of the ground structure in the present invention is calculated by the following [Equation 1].

[0026] [Formula 1]

SR (%) = (A / B) X 100

···· Number of threads inserted in the course direction between 1 inch

コース · · · Number of loops in the course direction between 1 inch The above-mentioned number ratio SR (%) is calculated using a three-dimensional structure warp knitted fabric at the time of finishing through a normal dyeing finishing process such as fine milling, dyeing, and heat setting.

[0027] Further, the insertion thread 4 is on the outer surface side of the ground structure in a range of 2 to 30 courses at a predetermined interval in the wel direction (exposure ratio of insertion thread 1: 1 to 1: 8), in particular. It is preferable to insert and lock so that it is exposed in the range of 2 to 20 courses. In other words, if the exposure force of the insertion thread on the outer surface is less than the course, the exposure effect of the insertion thread on the outer surface may not be conspicuous, and the exposure of the outer surface may be less than 30 courses. When the size is increased, the insertion yarn exposed on the outer surface of the ground yarn and the woven fabric is easily pulled, and if pilling occurs, the wear resistance may be deteriorated, which is not preferable.

[0028] The insertion yarn that can be used in the present invention is a yarn of 167 to 1400 dtex, preferably 220 to 1 OOOdtex, a multifilament yarn thicker than the yarn constituting the ground structure, or a spun yarn corresponding to this fineness. Alternatively, various yarns such as these crimping yarns can be used. Further, those having soft side surfaces such as molding yarns, spun yarns, processed yarns, etc., in which the side surfaces of the yarn have a hairy tone are preferably used. In addition, the tactile sensation is improved by raising the insertion thread with a puff. Furthermore, hydrophilic fibers such as cotton and rayon, or fibers excellent in sweat absorption such as synthetic fibers subjected to sweat absorption may be used. When the fineness of the inserted yarn is less than 167 dtex, there is a risk that the inserted yarn will not be able to exert a sufficient tactile feel that is difficult to appear on the outer surface of the ground structure, or the inserted yarn may be easily damaged. If it is larger than 1400 dtex, irregularities on the outer surface of the ground tissue become too large, and the tactile sensation may be deteriorated.

[0029] Further, in the present invention, it is preferable that the insertion yarn 4 is inserted and locked in the wel direction (knitting direction) between the loops of the ground structure by a method of insertion knitting by warp knitting.

[0030] Further, the outer surface of the ground structure including the insertion thread 4, for example, the outer surface structure 1, and the insertion thread 4 on the outer surface side.

As shown in FIG. 2, the difference in height from the (exposed insertion yarn portion 4a) is the total thickness C of the three-dimensional structure warp knitted fabric including the insertion yarn 4, and the three-dimensional structure warp knitting of the portion without the insertion yarn ⁴ . It is represented by the difference A from the total thickness B of the ground. The height difference between the insertion thread 4 and the surface of the ground texture is preferably 0.1 mm to 2. Omm, more preferably 0.2 mm to l Omm. If the difference in height between the inserted yarn and the surface of the ground texture is less than 0.1 mm, there is a possibility that sufficient permeability cannot be obtained in which the inserted yarn is difficult to be exposed on the surface of the ground texture. Also 2 If it is larger than Omm, the touch on the human body (skin) contact surface may be impaired.

[0031] As described above, the insertion yarn 4 is grounded so that the insertion yarn 4 is exposed at a predetermined interval on the outer surface of at least one of the front and back ground yarns and weaves 1 and 2 (outer surface yarn and weaving 1). By inserting and locking to the tissue 1, it is possible to provide a three-dimensional warp knitted fabric having excellent design and excellent tactile sensation on the outer surface of the ground tissue without impairing air permeability. Fig. 3 is a schematic perspective view of an example of the above-mentioned three-dimensional warp knitted fabric. Fig. 4A and Fig. 4B are schematic views of the case where the insertion thread 4 is exposed on the outer surface of the ground structure and the case where it is exposed on the inner surface. FIG. 5 shows an enlarged schematic sectional view of the sectional view.

In addition, as shown in FIGS. 6 to 8, the other ground structure (for example, the surface texture 1) opposite to the ground structure (for example, the lining texture 2) to which the insertion thread 4 is inserted and locked, In addition to a plain structure, a structure having an opening 5 as shown (for example, a mesh structure) can be used. In this case, the insertion thread portion 4b exposed on the inner surface of the ground texture 2 of the insertion thread 4 inserted in the other ground texture 2 can be seen from the opening 5 and has an excellent design. A body structure can be provided. FIG. 6 is a schematic perspective view of the above-described three-dimensional warp knitted fabric, and FIGS. A schematic cross-sectional view is shown, and an enlarged schematic cross-sectional view is shown in FIG.

[0033] A method and a form of insertion locking of the insertion thread 4 are performed at a constant interval in the knitting direction, that is, the wel direction, over at least one ground structure (exposure ratio of the insertion thread 1: 1 to 1: 8). And inserted and locked between the loops of the ground structure. The insertion lock state of the insertion thread 4 with respect to the ground structure and the exposed state of the outer surface can be set as appropriate according to the application. However, as shown in FIGS. It can be inserted and locked so that it is exposed on the outer surface, or it can be inserted in any shape such as stripes, checkers, dots. Needless to say, the surface of the ground can be knitted with a suitable structure according to its use and purpose, such as mesh or plain tissue.

[0034] The knitting density in the warp direction (knitting direction) of the three-dimensional warp knitted fabric of the present invention is 20 to 70 course Z inches, preferably about 25 to 50 course Z inches. If the knitting density in the longitudinal direction is less than 20 course Z inches, there is no sense of density on the surface of the ground structure when knitted, and the product value is inferior. May become heavy [0035] The fiber used in the present invention does not hinder its effect when used in a three-dimensional knitted fabric, and the fineness is not particularly limited as long as it is a fiber, but the fineness of the yarn forming the front and back texture is not limited. Monofilament yarns, multifilament yarns, or kage yarns of 33 to 500 dtex and 22 to 220 dtex of connecting yarn forming the gap are used.

[0036] As the types of fibers that can be used, acrylic fibers, polyamide fibers, polyester fibers and the like are suitable, but polyester fibers are preferably used in terms of durability.

[0037] The present invention provides a warp knitted fabric excellent in touch if the material feel because a material having a good texture and texture on the side surface of the yarn can be used for the insertion yarn to be inserted into the ground structure. You can. Further, by inserting the insertion thread so as to be exposed on the outer surface of the ground structure, the loop forming the ground structure is located below the insertion thread and is less likely to appear on the surface in contact with the human body, etc. Since the insertion thread is inserted without forming a loop, undulations are unlikely to appear on the surface of the ground structure.

[0038] Furthermore, the warp knitted fabric of the present invention exhibits the original performance of the yarn because the side surface of the insertion yarn exposed on the outer surface comes into contact with the human body or the like. Is used, it has a good tactile sensation when touched with a hand, and can be preferably used for applications that touch the skin surface. In addition, since a moderate interval and height difference can be made between the insertion yarn and the ground texture surface, it is possible to provide a three-dimensional warp knitted fabric with excellent breathability and low stuffiness.

Further, in the present invention, since the insertion thread is only inserted into the ground structure without forming a loop, the insertion thread jumps out of the loop, the base fabric is hardened, the ground surface is rough, and the appearance is not good. Even if a thick thread that consumes less insertion thread is used, a three-dimensional structure with a good appearance on the surface of the ground structure can be provided.
