Description

  In the present invention, two warp knitted base fabrics and a three-dimensional warp knitted fabric formed by connecting the base fabrics at intervals with connecting yarns, commonly called warp knitted spacer fabrics, are formed of jacquard yarns on at least one base fabric. The present invention relates to a mesh structure.

  Conventionally, the spacer fabric has been widely used in the fields of bedding, clothing, various industrial materials such as vehicle-related products and medical supplies. As for the form, one base fabric is plain, and the other base fabric is mesh-like, or both base fabrics have the same mesh tone, or have different mesh sizes. Is provided. In particular, in order to enhance the decorative effect on the appearance, a combination of a mesh structure in a plain base fabric and a combination of multiple types of mesh structures were considered in order to obtain functionality for use. Things have been devised.

For example, the utility model registration publication No. 2554813 discloses a three-layer warp knitted fabric composed of front and rear base fabrics and connecting yarns for securing gaps provided between these base fabrics, at least on one side Each wale formed of a stitch row constituting the base fabric of the base fabric is changed by the individual control to the jacquard guide for guiding the jacquard yarn, so that the position of the jacquard yarn on the knitting needle row is changed, for example, a large mesh ( Holes) and small meshes (holes) are formed, and these are combined to show that a pattern is formed and applied to shoes as a single application using the formed warp knitted fabric Is disclosed.
Utility Model Registration Gazette No. 2554813

  In the above prior art, the hole, that is, the knitted structure constituting the mesh is formed by controlling the jacquard yarn guided from one row of jacquard ridges. Knitting yarns that act alternately on two knitting needles to form a needle loop by providing a knitting course that continuously acts only on one knitting needle row, and knitting with the other knitting needle in this knitting course Needless to say, the needle loop which is not made up is supplemented by a chain knitting yarn introduced from another ground where the chain knitting is formed in all the knitting needles.

  For this reason, the formed mesh is composed of a wale in which the knitting yarn forms a double needle loop and a wale that forms a single needle loop, and as a result, the mesh squeezing degree is low as the entire knitted fabric. As a result, the size of the mesh could not be clearly expressed. Further, since the mesh is not balanced in terms of the strength of the knitted fabric, it is difficult to obtain the required physical properties, and it cannot be said that it is particularly suitable for uses such as an upper material of shoes.

  The present invention is a spacer fabric formed by connecting two warp knitted base fabrics and these base fabrics with connecting yarns, and at least one of the base fabrics is a jacquard yarn in which the knitted structure of the mesh is jacquard controlled. Since the mesh formed is clearly expressed and the roughness of the mesh is mixed, the mesh can be balanced and can be designed in consideration of physical properties. And a spacer fabric manufactured by the method.

In order to solve the above-mentioned problems, the present invention uses a warp knitting machine having two rows of needle bars with at least two rows of jacquard ridges, and uses a warp knitting machine and a connecting yarn for connecting these base fabrics. A spacer fabric comprising a jacquard yarn formed by passing two rows of jacquard ridges as a base fabric forming yarn in the formation of one base fabric. Underwrapping is performed in opposite directions by jacquard control, and the main part of the mesh base structure in which at least a coarse mesh part and a fine mesh part are mixed is formed by a change structure of jacquard yarn. is there.
The above-mentioned “underwrapping in the reverse direction” means that the jacquard yarns threaded through the two rows of jacquard ridges are swung in opposite directions on the same knitting course in the knitting needle row direction. It means forming a loop part.

  Further, the present invention provides a jacquard constituting a mesh formed by threading two rows of jacquard ridges in one base fabric of a spacer fabric including front and rear base fabrics and connecting yarns for connecting these base fabrics. The card yarn is underwrapped in opposite directions to form a spacer fabric in which a main body portion of a mesh structure in which at least a coarse mesh portion and a fine mesh portion are mixed is formed.

  According to the manufacturing method of the present invention and the spacer fabric obtained by the manufacturing method, when forming the ground texture on the mesh, the ground yarn to be formed is made into a jacquard yarn formed by passing two rows of jacquard folds, The jacquard yarn carrying the main body is knitted by underwrapping in opposite directions under jacquard control, so that the jacquard yarn is always pulled in the opposite direction and the jacquard yarns are tightened together. Therefore, a clear mesh form is obtained, and in the obtained spacer fabric, the ground yarn forming the mesh is only jacquard yarn controlled by jacquard, and no supplementary chain knitting is required. The knitted structure becomes a balanced mesh base fabric, and has desired physical properties by designing in consideration of the arrangement and roughness of the mesh.

  By providing it on the base fabric in three or more stages from a coarse mesh part to a fine mesh part, the decorativeness of the mesh appearance can be enhanced along with the functionality such as ventilation.

  By combining the plain texture in the mesh texture, and by configuring the pattern with the plain texture, the mesh texture retains functionality, and by configuring the jacquard pattern with the plain texture, The decorativeness is further enhanced, and a product effect is exhibited by putting a logo or the like using a plain texture.

  In forming one base fabric, jacquard yarns threaded through two rows of jacquard folds are underwrapped in opposite directions, so that a mesh fabric in which at least a coarse mesh portion and a fine mesh portion are mixed is mixed. In addition to forming the main part of the tissue and forming the ground structure of the mesh in the formation of the other base fabric, the spacer fabric is improved in decorativeness by one side constituting the mesh part, and the other side In the mesh part, functionality is enhanced more effectively.
