Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a three-dimensional warp knitted body having three-dimensional dimensions.

The warp knitted body of the present invention can be used as a horizontal blind material or a vertical blind material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The three-dimensional warp knitted body of the present invention and its manufacturing method will be explained with reference to figures showing one embodiment thereof.

The three-dimensional warp knitted body of the present invention is first knitted using a warp knitting machine as shown in FIG.

That is, it is manufactured by a double type warp knitting machine having a front needle bed 1 and a rear needle bed 2, both of length Q, which are arranged in parallel with a desired interval P between them.

The front needle bed 1 and the rear needle bed 2 of this double type warp knitting machine warp knit the surface warp warp A texture and the scarlet warp B texture having rough densities, respectively.

For example, as shown in FIG.
．． 4... and back yarn supply means 5, 5... are provided, and front knitting needles 6, 6... and back knitting needles 7, 7... are provided.

Therefore, the front warp warp surface A and the back warp warp surface B to be warp knitted have a structure in which the chain stitches a, . . . pass through the warp at each W interval, as shown in Figs. It will be done.

Although not shown in the drawing, each needle bed is provided with the same number of weft yarn supply means as the front yarn supply means and the back yarn supply means, and these chain stitches a and
. . . can be made by connecting adjacent warp chain stitches in the lateral direction with weft threads at intervals of V in the radial direction, resulting in an extremely coarse structure.

Further, pile yarn supply means 3 are provided at each position separated by a lateral distance ct between these needle beds 1 and 2.

A reciprocating texture C is created by reciprocating the pile yarn densely between the surface warp surface A and the crimson surface B, for example, for each chain stitch, by the neck swinging action of the pile yarn supplying means.

For example, as shown in FIG. 1, the horizontal spacing q of the pile yarn supply means 3 is set to 3W, and each pile yarn supply means 3 is provided to match the position of the chain knitting needles, and each The pile yarn is reciprocated one way between the front and rear needle beds 1 and 2 for each chain knitting, and entwined with the chain knitting needles to knit a dense reciprocating structure C at the same time.

Next, a heat setting mechanism made of synthetic resin and having a conventionally known structure is provided below each reciprocating weave position of the double warp knitting machine.

If the pile yarn is a heat-set synthetic resin yarn, the pile yarn can be solidified into a plate shape by the heat-setting mechanism.

Furthermore, after a heat-set synthetic resin or powder is sprayed and deposited, the reciprocating structure C can be solidified into a plate shape by passing it through the heat-setting mechanism. After being supplied to the reciprocating tissue from above, the reciprocating tissue C can be solidified into a plate shape while being bonded integrally with the reciprocating tissue C using a heat setting mechanism.

When the reciprocating structures C, C, . . . are solidified into a plate shape in this manner, a three-dimensional warp knitted body as shown in FIG.

In other words, it has a width close to the length Q of the needle bed, a thickness close to the distance P between both needle beds, and a plate-shaped reciprocating structure C, C... or the longitudinal direction at every distance q. It is possible to obtain a three-dimensional warp knitted body that is solidified.

In the example, a three-dimensional warp knitted body with the simplest structure was described for the sake of simplicity. In the structure C, the yarn feeding mechanism 3 is not necessarily used only for one pile yarn, but can also feed multiple pile yarns and reciprocate them, and can also feed reinforcing yarns in a direction perpendicular to the reciprocating pile yarns to create a woven fabric structure. It is also possible to create a reciprocating organization like this.

The three-dimensional warp knitted body of the present invention has two sets of needle beds arranged at a desired interval P.
By designing and manufacturing a double-type warp knitting machine with a special structure, products can be knitted extremely easily and at low cost.

The three-dimensional warp knitted body of the present invention has a reciprocating structure C7C that is heat-set and fixed using a heat-set synthetic resin, and this can be used as a slat equivalent for horizontal blinds and vertical blinds. This invention can be used as a material for blinds with special effects, and can be provided in large quantities at low cost.
