Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a stretch laminate base cloth for laminating the surface of a cloth.

<Problems to be Solved by Conventional Techniques and Inventions> As a laminated base fabric which is required to have elasticity, a material knitted by a tricot machine has a half structure or 8-course mesh structure using polyamide or polyester filament fibers. However, there is a large difference in the elongation rate of the background and the compatibility with the surface fabric is poor, and there is a problem in the laminating process, the sewing process and the forming process. Further, there is a problem in that the tension of the sewing machine thread and the thread breakage of the base cloth by the sewing machine needle may occur during sewing after laminating.

Further, there is a drawback that the laminating process is difficult due to the winding of the base cloth unless the base cloth is set to a high temperature once.

Therefore, in this invention, the strength against tears and tears is increased while maintaining a proper stretchability even after being laminated on the stretch laminate base cloth, and the strength corresponding to the sewing machine needle is improved.

<Means for Solving the Problems> The stretchable laminate base fabric of the present invention for solving the above problems is
In a knitted fabric in which a 6-course tulle structure was knitted with a warp knitting machine in the front reed, the sinker loop foot was
It is formed by waving between two needles through a needle loop between the needles, and the yarn from the back reed is shook between three needles every three courses, and when shook between three needles, it does not get entangled in the sinker loop foot of the front tissue. By forming one loop as described above, a triangle is formed in the hexagonal tulle.

<Function> Since the 6-course tulle structure has a similar elongation in the background and it is difficult to wind around the ear, in this invention, the back reed structure is shaken by 3 stitches every 3 courses based on the 6-course tulle structure. At the time of shaking between 3 stitches, that is, one loop is formed every 3 courses so as not to be entangled with the sinker loop foot of the front reed. In addition to the hexagon tulle, the sinker loop foot is a needle loop between 2 stitches. Since it is formed by waving between two stitches through the needle, a hexagonal tulle is formed into a triangle with diagonal lines by the back reed and sinker loop legs, which makes the tulle coarse. Prevent
It functions to tighten the stitches, promotes an increase in the area of adhesion as a laminated base fabric, and can enhance the reinforcing effect more than the usual tulle structure.

<Example> The knitting structure of the laminated base fabric of the present invention is shown in FIG.

(5) in the tulle knitting structure in the figure is a sinker loop foot, which is formed by passing through a needle loop between two needles and shaking between the two needles.

For the hexagonal tulle (4) consisting of the front thread (1), the back thread (2) is swung 3 stitches every 3 courses, and the sinker of the front thread (1) is inserted where the hexagonal tulle (4) enters. Loop (3) so as not to get entangled in loop foot (5)
2 courses are inserted by continuing to fix with, and one hexagonal stitch (6) consisting of the oblique line of this back yarn is formed in this hexagonal tulle stitch (4).

A specific example of the structure for knitting the above-mentioned base fabric by using the two reeds of the warp knitting machine will be explained below. As the material, both the front yarn and the back yarn are made of polyester denier fiber 75 denier 36 filament yarn.

As an organization, (Front) 1-0 1-0 1-0 1-2 1-2-2 1-2 (back) 1-0 1-1 0-0 2-3 2-2 3-3 The result of knitting at 69 courses / inch, and laminating the laminated base fabric (10) to a knitted fabric (20) 100% polyester brushed shirring as the surface fabric to be used for car seats and chair seats, for example. (Fig. 2), the texture is good and the background keeps an appropriate elongation.
Strongly against the tension of the sewing machine thread and the sewing machine needle, the ground thread does not break.

Regarding the material, it can be selected in a timely manner in relation to the surface fabric, and even when it comes to the thickness, it can be selected in a timely manner between 15 denier and 300 denier depending on the strength required for the texture of the outer material.

The organization of the front reed may be closed or open.

<Effect of device> According to the structure of the device, the sinker loop foot is formed by swinging between the two needles through the needle loop between the two needles, and the thread by the back reed is three needles every three courses. By forming a loop so as not to get entangled in the sinker loop foot (5) by waving, a trigonal eye (6) is additionally formed in the hexagon tulle to prevent the tulle from becoming coarse. Will tighten the stitches. Then, it becomes possible to sufficiently exhibit the appropriate degree of elongation of the hexagonal tulle stitch (4), and it is reinforced by the triangle stitches (6) to prevent the stitches from becoming coarse, and as a laminated base fabric. When used, the strength is increased, and the triangular area (6) increases the adhesion area, which improves the peel strength.

In addition, the back fabric (2) is not frayed from the cut surface in any direction, and the back yarn (2) is swayed by 3 stitches for every 3 courses. Therefore, the back fabric (2) is stable in the background and hard to wind around, and the base fabric is easy to handle.
