DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel patterning method and apparatus for a knitted fabric, a knitted fabric obtained by the method, a pleated fabric made from the knitted fabric, and a pleated fabric made from the pleated fabric. Related to knitwear.

[0002]

2. Description of the Related Art Hitherto, a predetermined portion of a knitted fabric has been cut out, a knitted fabric has been intentionally applied to the cutout portion with a different weaving line, and a pattern has been obtained. After forming into the desired outer shape (semi-finished product or product),
Techniques for performing pleat processing while the folds are folded are well known. However, these techniques require processing such as cutting and cutting of the knitted fabric itself, and the pattern and form to be expressed are intentional, and are not continuous with the flow of the weaving streaks of the knitted fabric.

[0003]

SUMMARY OF THE INVENTION According to the present invention, it is possible to express a continuous spiral pattern along the flow of the woven streaks of a knitted fabric by using its elasticity without performing any processing on the knitted fabric. A knit fabric patterning method and a device therefor which are provided as described above, and a knit fabric having a rich taste and a natural feel by the method and the device, and a pleated fabric made from the knit fabric, The purpose is to obtain knitwear made from the pleated fabric.

[0004]

In order to achieve the above object, according to the present invention, a tension frame 3 is inserted into an opening 2a of a bag 2 sewn with a knitted fabric 1 to tension the knitted fabric 1. Then, the endless lower frame 5 is placed on the lower side of the bag body 2, the endless lower frame 5 is tightly fitted to the outside of the endless lower frame 5 from above, and then the endless upper frame 6 is placed. In the framed state, the endless upper frame 6 and the endless lower frame 5 are rotated by an arbitrary angle and placed in a fixed state, and the dry heat table 4 is operated to dry and heat the entire knitted fabric 1 by heat spraying. Endless upper frame 6,
This is a knitted fabric patterning method characterized in that the endless lower frame 5 is removed, and a continuous pattern 8 based on a vortex along the flow of the weave is shrunk and exposed in the framed portion.

[0005] Further, in the above method, there is provided a knit fabric patterning method in which the endless lower frame 5 and the endless upper frame 6 are framed in a multilayered manner.

A knitted fabric obtained by each of the above methods, a pleated fabric 9 obtained by folding the knitted fabric to a predetermined pitch by a pleating machine, and further comprising a pleated fabric. It is knitwear sewn from the ground 9.

[0007] An endless upper frame 6 is fixed to the lower end immediately above the dry heat table 4 and reciprocates up and down with the upper dead surface of the dry heat table 4 as a bottom dead center and a set angle rotation operation at the bottom dead center. This is a device used for carrying out a knit fabric patterning method including an endless lower frame 5 and a tension frame 3 of the bag body 2 of the knit fabric 1 separately mounted on a step-down rotating shaft 7 provided with a stop operation.

Further, in the above-mentioned apparatus, the step-down rotary shaft 7 is composed of concentric sheaths 7a, 7b, 7c..., And has an endless upper frame 6 having a gradually increasing diameter from the lower side at each lower end.
a, 6b, 6c... are fixed in a multilayer manner, and separately provided with endless lower frames 5a, 5b, 5c.

[0009]

Now, the method of the present invention will be described in the order of steps with reference to the apparatus shown in FIG. (A) From the opening 2a of the bag 2 of the knitted fabric 1, the tension frame 3
The knitted fabric 1 is placed on the dry heat table 4 in a state where the knitted fabric 1 is tensioned, and an endless lower frame 5 is placed under the desired knitted fabric 1 bag 2.
Are arranged (FIG. 5A). (B) The operation switch (not shown) of the step-down rotary shaft 7 is pressed to lower the step-down rotary shaft 7, and the endless upper frame 6 fixed to the lower end thereof is fitted into the endless lower frame 5 (FIG. 5B). (C) At the same time as the endless upper frame 6 is fitted into the endless lower frame 5,
The step-down rotating shaft 7 and, therefore, the endless upper frame 6 and the endless lower frame 5 are both rotated by a set angle and placed in a fixed state (FIG. 6C). (D) Step on the foot switch 10 of the dry heat stand 4 to heat and heat the entire knitted fabric 1 by blowing the heat (Fig. 6d). Thermal irradiation may be performed several times depending on conditions. (E) With the heat radiation stopped, the step-down rotating shaft 7 is raised, and the bag 2 of the knitted fabric 1 after the drying and the remaining endless lower frame 5 are removed from the drying heat table 4 (FIG. 7E). (F) Finally, the tension frame 3 is removed from the bag 2 of the dry heat knitted fabric 1 to obtain a patterned knitted fabric 1 in a contracted state (FIG. 7F). (G) Pleated fabric 9 obtained by folding (pleating) the dry heat knitted fabric 1 from which the bag body 2 has been released at a predetermined pitch by a pleating machine is shown in FIG.

[0010]

[Embodiment of the Apparatus] An endless upper frame 6 is fixed to the lower end of the dry heat table 4 directly above the dry heat table 4, and the upper and lower sides of the dry heat table 4 are reciprocated vertically and the set angle rotation at the lower dead point. The step-down rotating shaft 7 to which the operation and the stop operation are given is mounted on the shaft. And separately, the endless lower frame 5 having a size closely fitted inside the endless upper frame 6.
And a tension frame 3 of the bag 2 of the knitted fabric 1. In the above description, the tension frame 3 may be the one that has been used for drying and heating the knitted fabric, and is preferably of a type that can adjust the length and width.

In the above apparatus, the step-down rotary shaft 7 is constituted by concentric sheaths of multi-axis shafts 7a, 7b, 7c..., And has endless upper frames 6a, 6b each having a gradually increasing diameter from the lower end. , 6c
Are fixed in layers, and the endless lower frames 5a, 5b, 5
It is also conceivable to provide an embodiment provided with c. According to this embodiment, it is possible to form a more complicated multilayer pattern.

[0012]

As described above, the present invention utilizes the stretchability of the knitted fabric to make it possible to display the continuous spiral pattern 8 along the flow of the weaving streaks of the knitted fabric. Therefore, both the processing time and the equipment therefor (although a certain equipment cost is required in a mode in which the step-down rotary shaft 7 on which the endless upper frame 6 is mounted is required), the frame stretching work, the endless lower frame 5 and the endless upper frame According to the means for manually rotating the frame 6 and twisting the framed portion with a weight or the like mounted thereon, the cost can be extremely low.

[0013] Since the embodiment of the pattern expressed by the present invention is the continuous spiral pattern 8 along the flow of the weaving streaks of the knitted fabric as described above, the knitted fabric has a natural feel and a rich taste. And pleats made from the knitted fabric,
Knitwear made from the pleated fabric can be obtained. The continuous pattern 8 can have various changes depending on the shapes and sizes of the upper frame and the lower frame, and with a multi-layered framework. It brings a change and adds to the beauty of the knit itself. The present invention will stimulate new demand for semi-finished knit products.
