Description

Reduced ruptured fabric, knitting method thereof and design system using the same

The present invention relates to a fabric for reducing cracking, a method of weaving the same, and a design system using the same.

In the past, a double-sided needle circular knitting machine was used to weave a fabric that forms a space between the surface of the fabric and the back of the fabric. In recent years, in addition to the production of quilted fabrics with a medium woven fabric between the surface of the fabric and the back of the fabric at the production site of the fabric, quilt weaving, corrugated weaving, tubular weaving, etc. are used on the side of the double woven fabric. Fabrics, etc.

At the production site of the fabric, in this fabric, the motif pattern and the motif pattern on the surface of the fabric are enlarged, and so-called "breaking" occurs, resulting in a significant drop in the quality of the fabric.

For example, in the quilting weaving, in the case of double-sided jacquard weaving using a double-sided needle circular knitting machine, the pattern of the surface of the fabric is woven by a needle cylinder, and the back surface of the fabric is woven by a dial, in order to prevent use on the side of the cylinder The woven thread remains on the dial side, sometimes on the dial side Weave of the pattern. At this time, in a case where a plurality of types of threads are used, the subject pattern knitted in a certain area on the side of the cylinder is alternately and repeatedly knitted by each line, and the boundary between the motif pattern and the motif pattern on the side of the cylinder is opposite. The longitudinal direction is separated and the problem of cracking occurs. This is because the boundary line of the motif pattern in the wale direction at successive plurality of courses is caused by the rupture saliency at the boundary line in the case where the same position in the wale direction is continuous, and the quilted fabric can be seen. The problem of the middle cotton or the quilted fabric protruding from the inside of the fabric causes a significant drop in the quality of the fabric.

[Example 1]

In the following fabric manufacturing, the V-LEC6DSIB 38-inch syringe 20 machine needle of the double-sided needle selector manufactured by Fukuhara Seiki Co., Ltd. was used.

As shown in Fig. 1, in the rib knitting of the six-feed structure based on the three-color jacquard pattern in which one course is knitted by using the three supply paths, the white line 2 and the blue line of the polyester processing line of 167 dtex 48 filaments are used. 3. The three types of red line 4 are inserted into two polyester processing lines of 330 dtex as the sewing thread (middle cotton) 1.

In the pattern, the cylinder pattern that becomes the surface of the fabric is a jacquard pattern in which a plurality of non-textured motif patterns of a certain area made of one of a plurality of types of threads are combined, and the dial pattern on the back side of the fabric is to be placed on the needle. An irregular bird's eye pattern in which each line other than the line used in the tubular pattern is alternately woven into a circle or a floating line in a row and a longitudinal direction.

Fig. 2 is a conventional example in which the dial pattern is a conventional bird's eye pattern. The upper part shows the braided structure of the dial and the lower part shows the braided structure of the barrel. Until the motif pattern in the syringe pattern changes, the needle-knitted thread moves from the syringe needle to the dial needle, and at the same time, the needle-knitted thread from the dial needle to the syringe needle starts from the change of the motif pattern mobile.

At this time, at a position common to the first supply path (F1), the second supply path (F2), the fourth supply path (F4), and the fifth supply path (F5), the line moves from the syringe needle to the dial needle. Or moving from the dial needle to the syringe needle, creating a boundary line of the motif pattern to form the boundary line 5. At this time, as shown by the arrow marks in FIG. 2, the third supply path (F3) and the sixth supply path (F6) are in the dial. The woven structure adjacent to the boundary line 5 is woven into a loop and a floating line, and the interval between the knitting loops of the respective supply paths is vacant, so that a space is generated and large cracking easily occurs.

The knitting method of Fig. 3 of the dial pattern of the first embodiment of the present invention is also the first supply path (F1), the second supply path (F2), the fourth supply path (F4), and the fifth supply path (F5). At the position of the CCP, the line moves from the needle to the dial needle or from the dial needle to the needle, creating a boundary line of the motif pattern, but at the third supply path (F3) as indicated by the dashed circle The braided tissue adjacent to the boundary line 5 formed by the boundary line of the motif pattern is continuously woven into a loop, so that the space is narrow and the crack can be alleviated.

Fig. 4 shows a syringe pattern, Fig. 5 shows a conventional dial pattern, and Fig. 6 shows a dial pattern according to Embodiment 1 of the present invention, in which a woven loop structure exists corresponding to one piece, and the line of the displayed color is woven into a circle. Other colors are woven by floating lines. Moreover, for convenience of explanation, FIGS. 4, 5, and 6 are each a view of the fabric viewed from the outside of the knitting machine.

As shown in Fig. 5, the conventional dial pattern is composed of a line other than the line used for the needle pattern, and each line is set to be alternately knitted into a loop or a float, but with the longitudinal direction of the motif pattern by the surface of the fabric. All of the boundary lines formed by the dividing lines are woven in a circle of differently woven fabrics on the back side of the fabric, thereby creating a space where large cracks are likely to occur.

On the other hand, as shown in Fig. 6, with respect to the dial pattern of the embodiment 1 of the present invention, all the boundary lines formed with the boundary line in the wale direction of the motif pattern in the stencil pattern are on the back side of the fabric. In the adjacent weave structure, one of the consecutive two rows is necessarily continuous and the same thread is woven into a circle, so that the space is not formed and the crack is reduced.

Fig. 7 shows a dial basic pattern in the first embodiment of the present invention. The portion corresponding to the motif pattern of the syringe pattern in the dial pattern is formed by the repetition of the base pattern. In the dial pattern of the first embodiment of the present invention, (a) indicates the theme of using the white line in the cylinder pattern. a dial base pattern of a portion of the pattern, (b) a dial base pattern indicating a portion of the motif pattern in which the blue line is used in the cylinder pattern, and (c) a needle indicating a portion of the motif pattern in which the red line is used in the cylinder pattern Plate base pattern. As shown in Fig. 8, it is inevitable that it is possible to form a loop in the longitudinal direction regardless of which of the dial basic patterns of (a), (b), and (c) is changed to which dial basic pattern. The organization, thus reducing the space between the motif pattern and the motif pattern to reduce the breakage.

The pattern in the present embodiment is formed using a design system based on a syringe pattern to automatically form a dial pattern. This design system determines the dial pattern of the portion corresponding to the theme pattern based on the line used for the motif pattern of the cylinder pattern, and thus the pattern is automatically produced. By using this design system, it is possible to shorten the production time of the pattern of the fabric which is reduced in cracking.

In the same manner as in the second embodiment, (a) shows the dial base pattern of the portion of the motif pattern in which the white line is used in the cylinder pattern, and (b) shows the dial base pattern of the portion of the motif pattern in which the blue line is used in the cylinder pattern. (c) shows a dial basic pattern in which a portion of the motif pattern of the red line is used in the cylinder pattern, and (d) shows a dial base pattern in which a portion of the motif pattern of the green line is used in the cylinder pattern.

As shown in FIG. 13, when the boundary line 5 reaches the middle of the basic pattern, the basic pattern 3 corresponds to the base pattern before the change and the basic pattern after the change, regardless of which dial basic pattern is used. In the case where the dial basic pattern is changed, the knitting structure adjacent to the boundary line of the dial basic pattern is inevitably continuously woven into a circle in one row in the continuous three courses. In addition, FIG. 13 shows a case where the theme pattern ends at the second wales from the left side of the base pattern before the change, since the third wales are originally reached from the left side, so that the changed basic pattern becomes corresponding thereto. The basic pattern of the third vertical line from the left.

The present invention is not limited to these embodiments, and for example, the needle pattern and the dial pattern may be replaced with each other as long as it is at least one of a continuous course of the number of line types which is one less than the number of types of lines woven by the jacquard used. The knitting fabric adjacent to the boundary line formed by the boundary line of the column motif pattern is continuously woven into a loop, and may be a pattern other than the pattern of the present embodiment, or a pattern in which the base pattern is not used. Further, other configurations may be employed as long as the base pattern is a base pattern in which at least one of the knitting structures adjacent to the boundary line of the other basic patterns is continuously knitted into a loop.
