CONSTITUTION:One side of woven fabric comprising synthetic fiber, natural fiber, mineral fiber, etc., is coated with a norbornene-based polymer having shape recovering properties in a layer state or the polymer melted in gap between warp and weft to give woven fabric having performance (e.g. automatic removal of wrinkles) of recovering a parent phase shape memorized at a temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a textile fabric that utilizes the shape recovery properties of norbornene-based polymers.

[Conventional technology] Conventionally, a glass transition temperature of 10°C or higher and a number average molecular weight of 1
A shape-recoverable molded article composed of a nobornene-based polymer of 1,000,000 or more is known (Japanese Patent Laid-Open No. 59-5
(See Publication No. 3528, etc.).

After this molded body is first molded into the matrix shape required for actual use, it can be deformed externally in a specific temperature range, cooled and solidified, and then heated again to a temperature above the specific temperature. is automatically removed and can be restored to its original shape or a shape close to it, and has conventionally been formed into a pipe, rod, or sheet shape.

[Problems to be Solved by the Invention] Conventional molded bodies are not suitable for use with adhesives, construction materials, construction fixing agents, medical equipment materials such as casts, tableware, stationery such as strawberries, ornaments, etc., especially objects. Although it has been used to transform into a specific shape or size by utilizing the properties of norbornene-based polymers, there has been a desire to develop further applications.

On the other hand, textiles used for clothing, obi, etc. are usually made of synthetic fibers, silk threads,
It is made of linen thread, wool, etc., and may wrinkle and lose its shape with use.

Therefore, the present invention proposes the application of norbornene polymers to the above-mentioned textiles as a new use, and aims to provide textiles from which wrinkles and the like due to use can be easily removed.

[Means for solving the problems] The woven fabric according to the present invention has at least one surface of the woven fabric body,
A norbornene-based polymer having shape recovery properties is coated in layers or melted and interposed in the gaps between the warp and weft.
It is characterized by

[Function] The woven fabric having such a structure is formed into a predetermined shape such as Japanese clothes or clothes, and then the correct shape (matrix shape) with creases necessary for actual use is memorized at a predetermined temperature. .

Therefore, even if these clothes etc. are stretched or bent and deformed during use, causing wrinkles, etc., the shape recovery properties of norbornene-based polymers will remove such wrinkles by heating them to a specific temperature again. is automatically removed and restored to its original shape.

[Example] Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is a woven fabric according to the present invention consisting of a woven fabric body 2 and a norbornene-based polymer molded body 3. The woven fabric body 2 is constructed by weaving a combination of threads made of twisted synthetic fibers, vegetable fibers, animal fibers, mineral fibers, etc. as warp and weft threads. The molded body 3 is made of norbornene-based polymer and is molded into a sheet shape, and is formed on one side of the woven fabric body 2 as shown in FIGS. 1 and 2 or on one side of the woven fabric body 2 as shown in FIG. 3. Laminated coating on both sides.

Here, as is conventionally known, the norbornene-based polymer has a glass transition temperature of 10°C or higher, preferably 20°C or higher, more preferably 30 to 60°C, and a number average molecular weight of 100°C or higher. It is more than 10,000.

Although the covering method is not particularly limited, for example, the sheet-like molded body 3 may be heat-sealed to the woven fabric body 2, or may be joined by a method such as adhesion. Further, the molten norbornene-based polymer may be applied to the surface of the woven fabric body 2, or may be melted and interposed between the warp and weft yarns.

The temperature and pressure when molding the norbornene polymer into a predetermined shape are not subject to any restrictions as long as the resulting molded product maintains a constant shape and exhibits strength properties that do not pose any practical problems, but usually the molding temperature is 100 to 200°C3, preferably 140 to 180°C, and the molding pressure is 1 to 200k
g/cm2°, preferably 50 to 150 kg/cm2.

Since the woven fabric 1 has a formed body 3 memorized in a sheet form joined to the woven fabric body 2 at the time of molding, even if wrinkles etc. occur, the woven fabric 1 can be properly treated within the range of above the deformation temperature and below the forming temperature. If the molded body 3 is heated by means of heating, the molded body 3 will try to recover into a sheet shape, so that the wrinkles and the like can be easily removed.

On the other hand, after forming clothes, Japanese clothes, etc. using this woven fabric 1, it is heated to a temperature higher than the above-mentioned forming temperature to memorize a predetermined matrix shape with creases necessary for actual use. Even if such occurrences occur, by heating to a predetermined temperature, wrinkles, etc. can be easily removed and the necessary creases can be restored in the same way as described above.

Next, examples of articles made of such textile fabric 1 will be explained based on FIGS. 4 to 6.

FIG. 4 shows trousers 4 as clothes made of the above-mentioned woven fabric l.

The pants 4 are memory-molded into the correct shape of the folds required for actual use as pants. Therefore, while worn, the pants 4 may stretch and their creases may come off, or they may become wrinkled due to bending, causing them to lose their shape.

In that case, please dry or iron these pants 4.
When heated with hot water or the like to a temperature above the deformation temperature and below the matrix forming temperature, for example 40 to 60°C, due to the shape recovery power of the norbornene polymer molded body 3 constituting the textile fabric l,
Clear creases are restored and wrinkles and the like disappear.

If the pants 4 are cooled after this heating deformation, the shape recovered to the original memorized shape is fixed.

The heating means is not particularly limited, and the pants may be heated to a temperature for restoring the matrix by ironing the pants, blowing hot air from a hair dryer, or soaking the pants in hot water.

In this case, the higher the temperature, the shorter the time required for shape recovery as long as the temperature is within the range of more than the deformation recovery temperature and less than the matrix forming temperature.

FIG. 5 and FIG. 6 respectively show the fabric l according to the present invention.
A packaging bag body 5 and a hat lining material 6 composed of
It shows.

The bag 5 is made by storing in advance a state in which the internal storage space is collapsed as a matrix form, and then heating it by soaking it in hot water for a few minutes to expand the internal storage space and inflate it. It is made into a bag shape, and this transformed shape is cooled and fixed. After this, when the packaged item is stored in the bag 5 during use and heated with a hair dryer, it will automatically return to its original flat shape, so the packaged item inside should be carefully monitored. It is packaged in a state in which

In addition, the lining material 6 of the hat is prepared by being transformed into a larger size than the matrix memory form, and after being worn on the head during use, it is gradually heated at a predetermined temperature to suit the size of the user. If heating is stopped when the shape has been reduced and recovered,
The deformed size is fixed at that point. Therefore, it can be modified and fixed to any size according to the size of the user's head.

The woven fabric l according to the present invention can be applied to various items such as Japanese clothes, belts, socks, helmets, supports for protecting joints, etc., in addition to clothes such as the above-mentioned pants.

[Effects of the Invention] The surface of the woven fabric of the present invention is coated with a norbornene-based polymer having shape recovery properties, or the norbornene-based polymer is melted and interposed between warp and weft yarns, so that the matrix shape is By memorizing this, even if wrinkles occur due to use, they can be easily removed by heating to a specific temperature.
