Description

  The present invention relates to a method for producing a fabric for roll blinds, pleated blinds, vertical blinds, or the like that is used indoors in a window or the like of a house or used indoors as a partition.

  Curtains used in ordinary houses are made with draped folds on the curtains, creating a pool of curtains to improve the beauty. However, such a curtain function requires space for storage, and there has been a problem in making the curtains and partitioning devices compact and simple. One method for solving this problem is a roll blind, a pleated blind, or a vertical blind curtain and a partition device. Using fabric with appropriate tension and hardness, folds are provided in a roll blind type that can be rolled up and down in the vertical direction, a vertical blind type that is separated into strips in the vertical direction, or pleated. If the pleated blind type that can be easily folded is used, the functionality can be improved by opening and closing the curtain in a compact manner. Furthermore, it is possible to improve the aesthetics with diversity, which is simple and clear, which is not found in ordinary curtains. For this reason, this type of blind type has been widely used in recent years.

These blind-type fabrics require appropriate tension and hardness so that they can be smoothly wound up or easily folded. In order to give the fabric proper tension and hardness, special resin processing is performed after knitting. In addition, flameproofing is also required, and processing is often performed at the same time. In this case, a processing method in which a resin imparting hardness and a flameproofing agent are simultaneously adhered to the fabric and heat-treated. However, in this method, hardness and flameproofness are generally contradictory to each other, so that advanced resin blending, technology, and experience are required, so that the processing cost is expensive. There is also a method of obtaining tension and hardness by heat treatment after weaving heat fusion yarn instead of hard finish resin processing, but it is difficult to control temperature and causes problems in fabric hardness variation. There is a case. An object of the present invention is to solve these problems.

The present invention is realized by the following means.
"Means 1"
In a knitting structure using a plurality of ground yarns, the warp A used for the ground fabric to be chain-knitted, the knitting yarn B used for the ground fabric to be inserted or knitted, or the knitting yarn B ′ used for the ground fabric to be further inserted and knitted, etc. In order to further increase the hardness of the fabric, the knitting yarn C used for the ground for inserting and knitting a denier yarn having a size of 10 to 50 and composed of a maximum of 15 single yarns. The above-described chain knitting warp A is passed through the chain stitches and locked in the transverse direction, or entangled in the chain stitches in the longitudinal direction, or a combination of the two, and several types such as A, B, B ′, etc. A method of manufacturing a blind type fabric using knitting yarn C as a means of adding a knitting yarn C to a knitting yarn structure.
"Means 2"
In the means 1, further, the heat-sealing yarn D is passed through the chain knitting warp and the left and right sides of the chain knitting yarn are locked, or tangled in the longitudinal direction of the chain knitting A, B, B ′, etc. , C, D Blind type fabric manufacturing method using knitting with several types of knitting yarn.
"Means 3"
In the means 1 or 2, the warp yarn A, the knitting yarn B, B ′, etc. or both the warp yarn A and the knitting yarn B, B ′, etc. A blind type fabric that does not require processing flameproofing.

1) By implementing the above means, the denier value of the single yarn size becomes extremely thicker than before, the rigidity of the fabric is increased, and the tension and hardness are optimal for the blind type fabric. In other words, the conventional hard finish resin treatment is unnecessary. Therefore, the manufacturing cost is low.
2) The present invention uses the optimum extra-thick yarn and, if necessary, the thermal fusion yarn in combination with the conventional method in which hardness is obtained only by heat treatment after weaving the thermal fusion yarn, Increased tension and hardness stability.
3) The conventional hard finishing process impairs the texture of the fabric because the resin adheres to the surface of the fabric, but since the resin is not used in the present invention, the texture of the fabric is utilized and the durability of the hardness is ensured. Is obtained.
4) Further, if necessary, knitting using a flameproof yarn for one or both of warp and knitting yarn can realize a blind type fabric that does not require post-flameproof processing.
5) Blind-type fabrics require moderate tension and hardness, and are also required to have flameproofing properties. However, it is difficult to obtain hardness and flameproofing functions by post-processing, so the processing cost is low. It was expensive. On the other hand, the present invention can be obtained at the same time by using the yarn used for knitting with the functions of hardness and flame resistance, and is inexpensive.

  This will be described below with reference to the drawings.

FIG. 1 is a diagram to which claim 1 of the present invention is applied. In order to knit the blind type fabric by knitting the yarn B on the chain warp A, and further increase the hardness of the fabric, a thick single yarn size knitting yarn C is applied to the above-described chain knitting warp A. The yarns are knitted with three types of knitting yarns A, B, and C while passing through the stitches and locked to the left or right, or tangling the chain stitches in the vertical direction. In FIG. 1, the trajectories of warp A, knitting yarn B, and thick single yarn knitting yarn C added to further increase the hardness are shown on the left side independently for each yarn. These yarn trajectories are created by a knitting jig called ground. And the figure which combined them and comprised the blind type fabric was shown on the right side, and the example of two knitting patterns is shown up and down. In other words, the knitting structure pattern 1 in the above figure expresses the case where the chain stitch is passed through and locked to the left and right, and the knitting yarn B is knitted zigzag across the two rows of warp A with respect to warp A. The thick single yarn knitting yarn C is an example in which the knitting yarn B is knitted in a zigzag manner over three rows of warp yarns A having a phase of 180 °. The knitting structure pattern 2 in the figure below is a warp A with chain knitting, while the knitting yarn B is knitted in a zigzag manner over the two rows of warp A, and the single knitting yarn C with a thick single yarn is one row of warp A. The knitting yarn B is an example of knitting at a position 180 degrees out of phase.
Claim 1 of the present invention is not limited to the example in FIG.
Denier is used as a unit of knitting yarn size. One denier means the size of a yarn when a 1 g weight of yarn material is stretched to 9000 m. FIG. 1 shows an embodiment of the present invention. As the knitting yarn C obtained by bundling four single knitting yarns having a large denier, a knitting yarn having a total amount of 60 deniers is used. In this case, the size of one single yarn is 60/4, that is, 15 denier single yarn. By increasing the total amount of 300 deniers and the number of single yarns to 10 and thus the single yarn size of 30 deniers, the hardness and tension can be further increased. Conventionally, the fabric is made up of chain knitted warp A and knitting yarns B, B ', etc., so that the necessary rigidity as a blind type fabric cannot be obtained simply by knitting with several types of knitting yarns. The fusion yarn was knitted, and then the hardness was obtained by heat treatment.
In contrast, in the present invention, a single yarn size of 10 to 50 and a denier knitting yarn C of 50 or less is further knitted with knitting yarns A, B, B ′, etc. By additionally knitting the yarn C, the hardness and tension of the blind-type fabric are increased by the synergistic effect of this knitting method and the knitting yarn C of a thick single yarn size.
In this case, the thick single yarn knitting yarn C is experimentally shown to have hardness and tension suitable for this application if the single yarn size is 10 or more and 50 or less and the number of single yarns is 1 or more and 15 or less. It is a practical range that I understand. That is, if the single yarn size is small, it is easy to knit, but the fabric has low rigidity. If the single yarn size is large, the rigidity increases but the knitting becomes difficult. There is an upper limit to the total amount of the knitting yarn C due to the rigidity and ease of knitting of the fabric, and the number of yarns is 15 or less from the above range.

FIG. 2 is a diagram to which a part of claim 2 of the present invention is applied. The trajectory of warp A, knitting yarn B, thick single yarn knitting yarn C to be added to increase the hardness, and heat fusion yarn D to be added if necessary to further increase the hardness is left for each yarn. The figure which was shown on the side and combined them to form a blind type fabric is shown on the right side. FIG. 2 also shows an example of two knitting patterns at the top and bottom. That is, in the knitting structure pattern 1 in the above figure, the knitting yarn B is knitted in a zigzag manner over two rows of the warp A with respect to the warp A, and the knitting yarn C of the thick single yarn is 180 ° in phase with the knitting yarn B In the upper pattern 1 in FIG. 1 of the example in which the warp yarn A is knitted over three rows, the thermal fusion yarn D is further zigzag across the two rows of warp yarn A with a phase difference of 180 ° from B. This is a braided example.
The lower knitting structure pattern 2 is an example in which the thick single yarn size knitting yarn C is zigzag across one row of warp yarns A at a position 180 degrees out of phase with B, compared to the upper drawing of FIG. It is. Claim 2 of the present invention is not limited to the example of FIG. 2, and the number of knitting yarns B is not limited to one, but may be a plurality of B ′ or the like.

FIG. 3 is a diagram adapted from a further part of claim 2 of the present invention. The trajectory of warp yarn A, knitting yarn B, thick single yarn size knitting yarn C added to further increase the hardness, and heat fusion yarn D is shown on the left side for each yarn individually, and they are combined to blind A diagram showing the type of fabric is shown on the right side. FIG. 3 also shows an example of two knitting patterns at the top and bottom. That is, in the knitting structure pattern 1 shown above, the knitting yarn B is knitted in a zigzag manner over two rows of the warp A with respect to the warp A, and the thick knitting yarn C is 180 ° out of phase with the knitting yarn B. In the upper pattern 1 in FIG. 1 of the example in which the warp yarn A is knitted in three rows of warp yarns A at the position where the heat fusion yarn D is knitted in a single row of warp yarn A in the same position as B. It is an example.
The knitting structure pattern 2 in the lower figure is different from the knitting structure pattern 1 in the upper figure in FIG. 3 in that the knitting yarn C having a large single yarn size is zigzag across one row of the warp yarn A at a position 180 degrees different from B. It is an example knitted into.
Claim 2 of the present invention is not limited to the example of FIG. 3, and the number of knitting yarns B is not limited to one, and a plurality of B's or the like may be used.

Although illustration is omitted, by using a flameproof yarn for both warp A or knitting yarn B, B ′ or the like, or warp A and knitting yarn B, B ′, etc., in addition to hardness, flameproofing Therefore, a blind type fabric that does not require post-processing flameproofing as in the prior art can be manufactured if necessary.

  The fabric made according to the present invention is a low-priced blind curtain that has the appropriate tension and hardness while making use of the texture of the fabric as a blind type fabric, and has practicality, grace, uniformity of quality, and low cost. Therefore, significant industrial contribution is expected.
