Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present application.

Referring to fig. 1 and 2, in the conventional weft-knitted packing fabric, a general packing yarn passes between upper and lower needle beds of a double-sided circular weft knitting machine, does not participate in any knitting motion, and exists only below a knitting needle, and a knitting pattern of a yarn packing area is shown in fig. 1, and a knitting pattern of a connecting area is shown in fig. 2. As can be seen from fig. 1 and 2, the filling jacquard fabric obtained in this way has filling yarns and threads between the upper and lower needle beds without participating in any knitting action, and the upper and lower needle bed loops are vertically wrapped in the fabric, so that the filling effect is embodied. However, the fabric has the most remarkable characteristic in cutting, the filling yarn can be easily extracted, and yarn running or yarn missing can occur in the subsequent cutting or sewing process, so that the situations of different thicknesses, uneven filling effect and fabric yarn missing are caused.

Aiming at the problems of the traditional weft knitting filling cloth, the invention develops a new manufacturing process to solve the problems and well improves the condition of filling yarn running. Generally, the technical scheme of the invention is to enable the filling yarns to participate in weaving, but the thickness of the filling part is not thicker than that of other parts, namely the obtained filling fabric is flat on the whole.

The technical scheme of the invention is elaborated as follows:

the preparation process of the weft-knitted filling yarn fabric capable of preventing yarn running comprises the following steps of:

designing an organization structure and carrying out full-computerized jacquard;

threading: the yarn filling area penetrates filling raw material yarns through a No. 2 yarn nozzle of the previous path of the yarn filling area which is completely discharged on the upper dial, in other specific embodiments, the yarn filling area can be used for any path, as long as the yarn is fed in the previous path of the yarn filling area which is completely discharged on the upper dial;

knitting the yarn fill area, the connecting area, and the yarn participating in a knitting area, wherein,

the knitting method of the yarn filling area comprises the following steps: the former path of the yarn which is completely discharged from the upper dial is filled with raw material yarn, passes through between the upper dial and the lower needle cylinder and is not woven; knitting the upper dial into a loop tissue; the lower needle cylinder is knitted into a loop tissue, and a specific knitting drawing is shown in figure 3;

the weaving method of the connecting area comprises the following steps: weaving lower looping and upper looping in sequence corresponding to the corresponding positions of the yarn filling areas; upper looping-floating; the lower looping-floating thread, the specific weave pattern is shown in figure 4.

The weaving is integrally woven by adopting a double-sided circular weft knitting machine, and different knitting instructions input into a computer are executed by knitting needles on the circular weft knitting machine when different parts are knitted. In the specific operation process, the initial height and the front and back of the yarn nozzle are manually adjusted and controlled by matching with a tuner so as to control the height of the yarn nozzle to adapt to the knitting requirements of different parts. The other operations are the same as the traditional weft-knitted filling fabric.

Referring to fig. 5 and 6, in the weft-knitted filling yarn fabrics for preventing yarn running provided by the two embodiments, the yarn-participating knitting regions do not represent the color of the filling material yarn of the yarn-filling region, that is, the yarn-participating knitting regions only represent one color of the used yarns, and have a larger contrast with the color of the filling material yarn of the yarn-filling region. And the yarn filling area comprises an inner layer, a filling layer and a surface layer, the surface layer is the surface exposed outside, and the surface layer is formed by weaving transparent fishing silks through a lower needle cylinder looping tissue. Therefore, the yarn form and the color of the yarn filled in the filling layer can be clearly seen through the transparent surface layer, and various patterns and designs can be designed in the yarn filling area according to a preset computer knitting diagram to form different cloth cover effects. And the layer which is not exposed outside when the inner layer of the filling fabric is used shows the color of all raw material yarns. The weft-knitted filling yarn fabric capable of preventing yarn running provided by the embodiment of the invention does not cause unevenness of the fabric due to the fact that the filling increases the thickness of the yarn filling area, and still keeps a flat plane.

The weft-knitted filling yarn fabric for preventing yarn leakage, which is prepared by the preparation process, is used for producing shoes, clothes, bags, sofas, bedding and the like, and can be cut, sewn and spliced according to requirements to obtain different products.

Compared with the filling yarn fabric provided by the traditional process, the filling yarn fabric provided by the invention has the greatest improvement that the phenomenon of yarn leakage and yarn leakage can not occur in the fabric cutting or sewing process, and the integrity and stability of the fabric can be still maintained even if the cut surface is in the yarn filling area and the yarn is not drawn or run. On the basis of enriching the appearance of the filling yarn fabric, the stability of the filling yarn fabric is greatly enhanced, and the application field of the weft-knitted filling yarn fabric is expanded.

It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
