Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be embodied in other specific forms than those described herein, and it will be apparent to those skilled in the art that the present invention may be practiced without departing from the spirit and scope of the present invention.

Please refer to fig. 1-1, which is a schematic diagram of a conventional cubic box-shaped fabric structure, and in order to research the cubic forming principle, a reverse thinking manner is adopted, E, F is the middle points of AD and BC respectively, the fabric is folded outwards along the plane where the middle points of the bottom surface and the top surface are located, and is unfolded to fig. 1-2, the box body part belongs to a conventional cylindrical knitting structure with front and back pieces having equal width and equal height, the longitudinal coils at the box bottom are connected with the horizontal coils of the box body one by one according to the arrow direction, and the realization cannot be realized in the actual knitting, after the vertical coils are knitted, the vertical coils are pulled into a cloth rolling device by a roller, and cannot be rewound to be sewn with the horizontal coils in time. The horizontal stitches can BE knitted first and then the vertical stitches are knitted, as shown in fig. 1-2, in which the vertical side A F ' of the front panel ABE ' F ' on the top surface is connected to the horizontal side AF of the cylinder, the vertical stitches are connected to the horizontal stitches while knitting, and the vertical stitches are connected to the horizontal stitches while knitting, which is an easy part to realize in the full-forming knitting.

Through the analysis, the bottom surface can not be directly woven according to the unfolding diagram of the drawing 1-2, and must be transformed and deformed, and the practical application is considered, such as a seat cover, a paper extraction box and the like, the bottom surface belongs to a plane covered on a desktop and the bottom surface, and is not directly exposed in a visual line, and the bottom surface does not need to be closed so as to smoothly put other objects such as paper extraction, a chair and the like, so that the objects can be wrapped by adopting a four-piece cross folding nesting method with reference to the bottom surface of a conventional paper box as shown in the drawing 2, and after transformation, as shown in the drawing 3, the weaving height d of each piece needs to be more than b/2, and an overlapped and crossed part is reserved.

To further illustrate the weaving method after conversion, the weaving process of the full-forming cubic fabric with a wider bottom surface comprises the following steps:

(1) unfolding and converting the cubic box-shaped fabric along a central line into a shape 3, wherein the shape comprises a box bottom part, a box body part and a box cover part, the box bottom part comprises a box bottom back piece facing to the outside and a box bottom front piece facing to the inside, the box body part is connected into a cylinder shape by the box body back piece facing to the outside and the box body front piece facing to the inside, the box cover part comprises a box cover back piece facing to the outside and a box cover front piece facing to the inside, and the box cover back piece and the box cover front piece are symmetrical along the central line of the cubic fabric;

(2) knitting is carried out on the four needle beds, a box bottom back piece, a box body back piece and a box cover back piece are knitted on the back needle bed, and a box bottom front piece, a box body front piece and a box cover front piece are knitted on the front needle bed;

(3) the box bottom part and the box body part are respectively knitted into a conventional tubular fabric on a front needle bed and a back needle bed;

(4) as shown in fig. 4, wherein 1-n are schematic knitting diagrams of the junction of the box body and the box cover; specifically, the method comprises the following steps:

step a, continuously knitting the box cover part upwards after the box body part is knitted, as shown in figure 1, the middle light-color coil is a part to be knitted on the box cover and corresponds to a plane with the width a and the height b/2 in figure 3, and the two side dark-color coils are parts to be stopped from knitting and gradually move needles and correspond to a plane with the width b/2 and the height c in figure 3;

step b, weaving the rear piece of the box cover to the right, and meanwhile, moving a needle inwards for connecting the left box body coil with the box cover;

step c, weaving the front piece of the box cover leftwards, and meanwhile, moving a needle inwards to connect the box cover by the right box body coil;

d, repeating the step b and the step c until the coil of the box body in the step n is completely moved to the part of the box cover, and completing the connection of the box body and the box cover;

in the step (4), the edge connection of the box cover and the box body part can be regarded as a connection model of a T-shirt and a large body, and when the box cover is woven, the horizontal coils at the edges of the side edges of the box body are connected with the longitudinal coils of the box cover one by one according to a certain weaving proportion;

(5) after the box cover is connected with the side edge of the box body, the front piece and the rear piece of the box cover are closed and sewed by adopting a shoulder narrowing model.

By adopting the weaving process, the three-dimensional braided fabric is unfolded along the central line, when the bottom surface is higher, the situation that the back piece is woven for a longer time and the front piece is always kept still can not be generated, the difficulty in actual weaving is avoided, and therefore the weaving can be smoothly carried out without increasing the performance of a sinker or tension.

In order to ensure the wear resistance of the bottom surface, yarns with higher twist can be adopted as the upper bottom surface of the raw material, a double-faced weave structure or a yarn clamping structure and the like can be adopted as the weave structure, and the thickness and the durability of the fabric are improved. To ensure that the four pieces are independent of each other, four yarn jets are used to knit the four pieces of area separately.

The weaving process of the fully-formed cubic fabric with a wide bottom surface provided by the application is described in detail, the principle and the implementation mode of the application are explained by applying specific examples, and the description of the examples is only used for helping to understand the method and the core idea of the application; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
