Abstract

PURPOSE:To obtain a long loopy fabric with excellent productivity by using soluble yarns in either of upper and lower ground weaves, simultaneously weaving the yarns so as to connect a space between the upper and lower ground weaves with a loopy material, then dissolving the aforementioned soluble yarns and removing either of the upper and lower ground weaves. CONSTITUTION:Soluble yarns such as water-soluble yarns are used in weft or warp yarns constituting either of upper and lower ground weaves and both upper and lower ground weaves are nearly simultaneously woven so as to connect a space between both the ground weaves with a loopy material. The aforementioned soluble yarns are then dissolved and treated to remove either of the upper and lower ground weaves.

Description

[Detailed description of the invention] [Industrial application field]

The method of the present invention relates to a method of manufacturing a long loop fabric by weaving a long loop fabric.

[Conventional technology]

When loops are formed on the upper surface of a fabric such as a towel or carpet, the weaving is done by loosening a predetermined warp thread by a predetermined amount due to the reciprocating movement of the reed. However, there is a limit to the size of the loop that can be formed using this method, and long loops cannot be formed. Therefore, conventionally, when forming a long loop, a core material of the desired loop length is interposed between a predetermined warp thread and woven, and then the core material is removed and a long loop fabric is woven. I have to.

[Problem to be solved by the invention]

Weaving long loop fabrics using the conventional method described above first requires a great deal of effort to place the core material in a predetermined position to form the loop, and to remove the core material after weaving. However, there were problems in that productivity was extremely poor and manufacturing costs were also high. Moreover, when the core material is removed after weaving, the loops are often damaged or cut by the core material, which poses a problem in that high-quality loops cannot be stably produced. Therefore, the present invention was proposed in view of the above problems.
It is an object of the present invention to provide a method for manufacturing a long loop fabric that can easily and stably weave a high quality long loop fabric.

[Means to solve the problem]

In order to achieve the above object, the method for manufacturing a long loop fabric according to the present invention involves weaving a top fabric and a base fabric almost simultaneously, and weaving a loop material between the two fabrics in a connected manner. The warp or / that forms the ground texture of either the base texture or the base texture
and the warp is woven with a dissolvable thread, and the dissolvable thread is dissolved after weaving the fabric to remove either the top fabric or the base fabric to form a long loop. It is something.

[For use]

For example, when planting a loop in the underlying tissue, the loop material forms part of the underlying tissue in the part of the underlying tissue where the loop is not implanted, and in the part where the loop is implanted, the underlying tissue changes from the underlying tissue to the overlying tissue. After moving on to form a part of the upper fabric, the weaving returns from the upper fabric to the underlying fabric, and continues to be woven to the part where the loops are to be planted while forming part of the underlying fabric again. Furthermore, when it comes to the part where the loops are to be planted, the above-mentioned operations are repeated, and the loop material is woven in a state in which the upper fabric, the underlying fabric, and the loop material are sewn between them. Next, when the dissolving yarns of the warp and/or warp that form the base texture of either the top texture or the base texture are dissolved, the texture is broken down into warp or warp threads and removed, and the long loops are removed. The formed underlying tissue remains.

【Example】

An embodiment of the method for manufacturing a long loop fabric according to the present invention will be described below with reference to the drawings. FIG. 1 shows a side view of the loop fabric during manufacture, and reference numeral 1 in the figure generally indicates a double-edged fabric consisting of a top fabric 2, a base fabric 3, and a loop material 4. This double-edged fabric 1 has, for example, warp threads 5 and 6 of the upper fabric 2.
The two healds are used to control the warp threads 7 and
a minimum of five healds (not shown), two healds for controlling the loop material 8, one heddle for controlling the loop material 4, a dobby device for controlling the opening of each of these healds, and a weft. Weaving is carried out using a yarn feeding device (not shown) formed of 9/10 shirt bolts or the like. For example, to explain the case where long loops 11 are planted in the base fabric 3, first, the healds of the loop material 4 have warps 7 and 8 of the base fabric 3 in the portions of the base fabric 3 where the loops 11 are not planted. Shedding is controlled along with one side of the weft l.
O forms part of the base structure 3. When it comes to the part where the loop 11 is to be planted, the healds of the loop material 4 move from the base fabric 3 to the top fabric 2, and the shedding is controlled along with one of the warps 5 and 6 of the top fabric 2, and the weft threads 9 Forms part of the ground tissue 2. At this time, the weft yarns 9 of the fabric fabric 2 are made of heat-melting yarns. After the loop material 4 forms a part of the top fabric 2 in this way, it returns from the top fabric 2 to the base fabric 3, and continues forming a part of the base fabric 3 again until it reaches the part where the loop 11 is to be planted. Furthermore, when it comes to the part where the loops 11 are to be planted, the above-mentioned operations are repeated to weave the fabric 1 in a state where the upper fabric 2 and the underlying fabric 3 are sewn together with the loop material 4. The double fibrous fabric 1 shown in FIG. is thermally melted and removed as shown in FIG.
The underlying tissue 2 is also removed at the same time, leaving the underlying tissue 3 in which long loops 11 are formed, as shown in FIG. Incidentally, in the above embodiment, a long loop is formed in the base tissue 3, but when a long loop is suspended from the top tissue 2, it can be formed in the same manner as described above. Further, in the above embodiment, the weft yarn is made of heat-melting yarn, but a part or all of the warp threads of the ground texture to be removed may be made of heat-melting yarn, or heat-melting yarn may be used as the weft yarn. Of course, it is also possible to use a water-soluble thread instead.

【Effect of the invention】

As explained above, according to the method for manufacturing a long loop fabric of the present invention, the top fabric and the base fabric are woven in a state entwined with the loop material, and the top fabric and the base fabric are woven together. The warp and/or warp that form either one of the ground textures are formed from dissolving threads, and the dissolving threads are dissolved and lengthened by simply processing the melted threads with a fabric post-processing device such as scouring or bleaching. Since it is possible to manufacture one-dimensional loop fabric, it is possible to omit the work of placing the core material at the predetermined position to form the loop and the work of removing the core material after weaving, which is required in conventional methods, resulting in increased productivity. This has made it possible to significantly reduce manufacturing costs through mass production. Another advantage is that when the core material is removed after weaving, the core material does not damage or cut the loops, making it possible to stably produce high-quality long loop fabrics.
