Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a multi-layered cloth, a part of which is integrally joined. More specifically, the present invention relates to a winding method in which a wrinkle does not occur in a multiple cloth having a bag portion.

[0002]

2. Description of the Related Art A multi-layered fabric in which a plurality of fabrics are laminated is
Used in various fields such as clothing, interiors, and industrial materials. Until such a fabric is finished into a final product, it starts with a weaving or knitting process, and then undergoes many processes such as inspection, scouring, drying, heat setting, dyeing, and finishing such as resin processing. Go through.

In these steps, in order to maintain the quality of the multiple cloth, in many cases, it is wound into a roll and operated and conveyed in each step. That is, in one step, it is unwound from the roll, subjected to some treatment, and then wound again on the roll. At this time, in the multiple fabric having the bag-shaped portion, the non-joined portions other than the integrally joined portion move freely to some extent, and a shift occurs between the fabrics. Therefore, when winding a multi-layered cloth having a large thickness, the winding diameters among a large number of cloths constituting the multi-layered cloth are different although they are minute. That is,
Since the cloth located closer to the inside has a smaller winding diameter, wrinkles are likely to occur during winding.

The wrinkles are good if they are slight, but if they are stored for a long period of time or if the multiple fabrics are wound while the temperature is high, the wrinkles will remain semipermanently and will not disappear in the subsequent steps. Will reduce the quality of. Therefore, in the past, the tension was extremely soft and soft when winding.
Alternatively, instead of winding it in a roll, it was shaken off on a dolly or the like so that no wrinkles would remain. However, the former requires a special winding device capable of adjusting tension, and it is difficult to increase the winding amount. Although the latter does not cause wrinkles, it does not have a practical solution because it causes creases and requires more storage space than winding.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for winding multiple fabrics in which winding wrinkles do not occur.

[0006]

DISCLOSURE OF THE INVENTION The present inventors have found that when a multi-layered fabric, in which a part of a plurality of laminated fabrics is integrally joined in the thickness direction, is wound on a cylindrical tube, it has a wrinkled state. The present invention has been achieved through intensive research. That is, the present invention is a method of winding a multiple cloth, in which a plurality of laminated cloths are partially integrally joined in the thickness direction, onto a winding core of a cylindrical tube, in which a cushioning material is wound on the surface of the winding core in advance. A method for winding a multiplex fabric, comprising the step of attaching and then winding up the multiplex fabric over the cushioning material.

The present invention is a method for eliminating the occurrence of winding wrinkles by winding a multi-layered cloth, which is likely to cause winding wrinkles and is partially integrally joined, in advance on a cylindrical tube around which a cushioning material has been wound. .. In the present invention, it is important that the cushioning material is wound around the core of the cylindrical tube for winding the multiple fabric having the bag-shaped portion in advance. Due to the cushioning effect of this cushioning material, an extremely flat surface state is maintained without unevenly pressing the wound multi-layered fabric and fixing the wrinkles that occur.

The cushioning material referred to in the present invention may be any cushioning material that does not fix the wrinkle when the multiple cloth is wound up, but it is a cushioning material having some degree of repulsion. For example, a concavo-convex molded sheet, a corrugated sheet, various foamed sheets, a sheet having an air column, an air cap seal sheet, a cloth rich in elasticity, a laminate of these, a composite sheet, and the like, but are not limited thereto. Absent.

The core of the cylindrical tube for winding the multi-layered cloth having the bag-like portion used in the present invention may be selected from those usually used in the manufacturing and processing of the cloth, for example, paper tube, wood tube, Examples include metal pipes, hanging pipes, and composites of these. In addition, the multiple fabric targeted by the method of the present invention is most effective in the case of a fabric having a bag-shaped hollow portion surrounded by these joint portions, where the integrally joined portions are continuous. However, the shape, spacing, ratio to the total area of the fabric, etc. of the hollow portions are not limited.

Further, a plurality of cloths constituting the multiple cloth includes woven fabric, knitted fabric, non-woven fabric, sheet, film, net,
It is a planar body such as a lattice-like sheet, or a laminate of these. The method for integrally joining a plurality of cloths may be any method such as a weaving method, a cloth making method that is performed at the same time as knitting, a stitching sewing method, a stitch method, an adhesion method such as adhesion or welding, or a composite method thereof. It is not particularly limited. Further, these multiple fabrics may be laminated with resin, rubber, film, sheet, etc. in order to impart airtightness, or in order to impart designability,
It may be dyed or printed.

The winding method of the present invention may be applied to any process as long as it is a process for handling multiple fabrics, and may be applied to a plurality of processes. The material of the fiber yarn used for the fabric constituting the multiple fabric of the present invention is not particularly limited. For example, polyamide fiber such as nylon 6, 66, 46, aramid fiber represented by paraphenylene terephthalamide, copolymer with aromatic ether, polyester fiber represented by polyalkylene phthalate, wholly aromatic polyester fiber, Vinylon fiber, rayon fiber, polyolefin fiber such as ultra high molecular weight polyethylene, polyoxymethylene fiber, sulfone-based fiber such as paraphenylene sulfone and polysulfone, polyether ether ketone fiber, polyimide fiber, polyether imide fiber, carbon fiber, etc. However, in some cases, inorganic fibers such as glass fibers, ceramic fibers, and metal fibers may be used alone or in combination.

The material of the fiber yarn may contain various additives which are usually used for the productivity in the manufacturing process or the processing process of the raw yarn or for improving the characteristics.
For example, it may contain a heat stabilizer, an antioxidant, a light stabilizer, a smoothing agent, a plasticizer, a thickener, a pigment, a gloss imparting agent, a flame retardant and the like. As described above, the winding method of the present invention can maintain the quality of the multiplex fabric at an extremely high quality, but the end use of the fabric is not particularly limited.
Depending on the shape of the integrally joined portion, there are, for example, a rectangular, polygonal, circular, oval, or other bag-shaped cloth, or a striped or ridged bag-shaped cloth, and the cloth may be used as a whole or a bag. It may be separated from the cloth and used as a bag for storing gas, liquid, solid, powder, granules and the like.
