Description

DETAILED DESCRIPTION OF THE INVENTION (N) Purpose of the Invention (1) Regarding Prior Art and Weaving The present invention relates to a widening fabric and a weaving method as described in item 7.

Conventionally, there were shrinkable yarns made of chemically synthesized fibers that only contracted unilaterally when heated, and there were fabrics woven from such yarns and non-shrinkable fiber yarns that were made to shrink throughout the area by heat processing. @ However, this shrinkable chemical synthetic fiber yarn shrinks infinitely when exposed to heat, so the product shrinks and at the same time the non-shrinkable yarn that is woven or twisted with the shrinkable chemical synthetic fiber yarn. This has the disadvantage that it becomes a ring and embossed on the surface of the woven fabric, reducing the value of the part as a woven fabric product and making the product unusable. Therefore, in homes, etc., such products have the inconvenience of not being able to get them close to a heat source such as a stove, and this is something that the general public has often experienced.

(2) Problems to be solved by the present invention In view of the above-mentioned problems of the prior art, the present invention provides a method for producing textiles in a wide range of areas using a single chemical synthetic fiber yarn that is stabilized in elongation by heat treatment at foot temperature. We provide textile products that do not shrink below a certain temperature, and when weaving, we use narrow-width fabrics (therefore, if we do not have a loom that can weave fabrics of the desired width, we only use fabrics that are narrower than the desired width). It is an object of the present invention to provide a woven fabric and a method thereof, which can be woven using a loom that cannot be woven, and which can be woven to a desired width using an appropriate back width machine or finishing machine, and can be finished at the same time.

+31 Regarding the structure of the invention The present invention is provided for the above-mentioned purpose, and the structure will be explained next.O First, a constant expansion/contraction rate at a constant temperature! A twisted yarn (3) is made of a stretchable chemical synthetic fiber (1) which is made to be stable and stretchable at a certain rate by heat treatment, and a non-stretchable fiber (2) which does not stretch by heat treatment etc. ), and the twisted yarn (3) is heat treated at a temperature higher than the stable temperature to shrink at a constant rate. For example, if you want to weave a 1.5m wide fabric, you may not have a loom capable of weaving a 1.5m wide fabric, or if you were weaving a 1.5m wide fabric, it would take time. C: If you don't have a kitten due for delivery, you can quickly make two pieces using a loom that can weave 1 meter wide fabric! It is extremely efficient to weave and then widen the fabric to a width of 1.5 m, or, depending on the type of fabric, to perform finishing and width shaping at the same time. Therefore, in such a case, the twisted yarn (length of 3J is 1.5
Using a twisted yarn (3) using a stretchable chemical synthetic fiber (1) that shrinks by 50 an when heat-treated at m ) is contracted by the length, and the twisted yarn (3') 7a, which has been contracted by the length during this time, is woven using a loom that weaves a 1 m wide fabric as the weft. Next, this 1 m wide fabric (41) was put through a width-setting machine (7) having a 1.5 m inside and a heating device (6), and heated to a temperature higher than the shrinking heat treatment temperature using the heating device (6). Woven fabric (4)! While being heated and conveyed by the conveyor belt (IQ) of the width-setting machine (7), the weft yarn (3')' is stretched and restored to the length before contraction. With a width of 5 m, the stretchable chemical synthetic fiber is stable and becomes a woven fabric that does not shrink at temperatures below the opening heat treatment temperature.

Note that the width adjustment process may be performed simultaneously by attaching a heating device (9) to a finishing machine (8) having a 1.5 m interior. Further, as a heat treatment method, treatment with hot water, steam, or hot air may be used, and the technique does not matter.

(4) Functions and Effects of the Invention The present invention has the above-described configuration, and its functions and effects will be described next.

Figure 1 shows stretchable chemical synthetic fibers (1) and non-stretchable fibers (1).
All you have to do is leave the twisted yarn (3) twisted together with 2).
Currently, such stretchable chemical synthetic fibers (υ) have been developed, so manufacturers can use the twisted yarn (3) according to the width of their P9r* looms. Of course, it is possible to use twisted yarn (3') that has been shrunk at a certain rate, or textile manufacturers themselves can heat-treat the twisted yarn (3) to shrink it at a certain rate and use it. .

As shown in the second figure, the elastic chemical synthetic fiber (1) shrinks at a certain rate and the non-stretchable fiber (2) shrinks due to heat treatment. I
J is in a state where he is being held back. This twisted yarn (3
) Using 'I', for example, when weaving a fabric with a finished width of 150an, if the loom is for 120an width, then 2
Shrinkage rate of 0! Twisted yarn (3 strands or twisted yarn (3')) using the stretchable chemical synthetic fiber (1) may be selectively used as the weft yarn.

In such a case, a 120-width cloth is produced on a 120-width loom, and then a heating device [193 is attached to the textile finishing machine (8)] is used to finish the fabric on a textile finishing machine (8). Heating at a temperature that is at least higher than the dye heating temperature, finishing and widening are performed at the same time to increase the width by an amount equivalent to 20% of the previous shrinkage, resulting in the required 150cro paper fabric, and elastic chemical synthesis. The fiber (1) is stabilized at the temperature. The heat treatment temperature for widening processing varies depending on the intended use of the fabric, but for example, if it is used around a stove at home, the temperature is 14°C.
We offer heat treatment at around 0℃! It is desirable to do so. Therefore, when used as a textile or product, the maximum temperature that the product will experience in the environment in which it will be used! Assuming,
If the heat treatment is performed at a temperature higher than that and the stretching process is performed, the stretchable synthetic fiber (1) will be stable at the temperature, and will not shrink unless the temperature is higher than the temperature.

Note that, of course, the width adjustment may be performed using a width adjustment machine (7) having a heating device kt6JY. No matter which method is used to widen the width, both sides of the fabric (4) (1)) 'a' are stretched before the width is contracted, and the stretchable synthetic fiber (1) is pulled up during contraction. The non-stretchable fibers (2) that had been stretched are also stretched and restored to the length before contraction.

If you use the above method to make a weaving cloth, the cost will be 151'r. Keniso σ who abuses even when he does not own the loom to weave
Not only is it possible to select T31 twisted yarn or twisted yarn (3 ribs) and weave it into a fabric with a width of 100,000 yen to the required width, but it can also be used as a woven fabric with a narrow width initially. Since the weaving is narrow, the weaving efficiency is improved and the weft insertion round trip time is shortened.) Also, the width of the fabric is stable at the heat treatment temperature for width-out processing, so it is stable at that temperature. Stretchable chemical synthetic fibers (1) have the advantage of not shrinking even when exposed to the following temperatures, and the component value of the fabric is also increased.

Furthermore, since the temperature for the widening heat treatment need only be equal to or higher than the shrinkage heat treatment temperature, there is an advantage that the widening heat treatment temperature can be freely selected depending on the intended use of the fabric.

There is no need for a wide loom to support the loom, so there is an advantage in terms of location for installing the loom, and it is economical. Since it can be cut, it has the advantage of being able to produce fabrics that exceed the capabilities of the loom.

Furthermore, it has many advantageous effects, such as the ability to weave a fabric of any width even within the elongation rate range of the stretchable chemical synthetic fiber (1).
