Description

The present invention relates to textile products containing chemical fibers, particularly garments containing chemical fibers.

Many of the textiles and garments sold today, especially functional garments made from outdoor clothing or other synthetic fibers, are formed from synthetic resin fibers in a non-negligible proportion. Such textile products have a drawback that the synthetic resin fiber or the synthetic resin fiber piece is washed off or falls off during washing, and it flows out into the environment together with the wastewater. Since the synthetic resin fibers to be washed off are usually extremely small and short fibers or fiber pieces, the fibers cannot be sufficiently collected by the drain filter of a conventional washing machine. Sewage treatment plants can collect a certain percentage of synthetic resin fibers in wastewater, but at the same time allow a relatively large proportion of such fibers to pass through, which promotes river and marine pollution to a non-negligible level. It is then taken up into the food chain by predation by animals.

Of course, it is ideal that washing machines, sewage treatment plants, etc. are equipped with appropriate microplastic filters, but this is not yet comprehensively achievable.

In this regard, according to Unpublished Patent Document 1, it is known that clothing containing synthetic resin fibers is washed in a washing machine using a specially formed washing bag for accommodating clothing. The washing bag functions as a means for collecting synthetic resin fibers washed off from clothing during the washing process. The synthetic resin fibers accumulated in the washing bag during the washing process can be taken out from the washing bag and properly disposed of after the washing process is completed, which contributes to the reduction of wastewater pollution by the synthetic resin fibers. However, this eco-friendly effect is only achieved by households who decide to buy similar laundry bags for environmental protection reasons.

Further, for example, from the prior arts described in Patent Document 2, Patent Document 3, and Patent Document 4, a washing bag for mechanically washing a fragile textile product is already known. Such a laundry bag is a protection for clothing contained in the bag during the washing process, such as a brassiere, or other textile products that are washed simultaneously during the same washing process, such as during the washing process. It acts as a protection against hooks that may be present on the clothing contained in the laundry bag. This laundry bag has no role in terms of environmental protection.

German Patent Application No. 1020116100493 German Utility Model No. 8404746 (U1) German Utility Model No. 20104636 (U1) U.S. Pat. No. 4,630,312

From the viewpoint of the above-mentioned prior art, an object of the present invention is to significantly reduce wastewater contamination by synthetic resin fibers when washing textile products or clothing containing synthetic resin fibers by an extremely simple and easy method for the user. To improve as much as possible.

The above-mentioned problem is solved by the textile product containing the synthetic resin fiber according to claim 1. Further, preferred additional configurations of the invention will be revealed by the dependent claims and the detailed description of the invention.

The textile product according to the present invention can be preferably made into clothing, but the textile product contains a closed wash bag, and the wash bag is heat-cured with an average mesh width in the range of 5 μm to 200 μm. When formed from a sex synthetic resin mesh structure, and the size of the washing bag is suitable for fully containing clothing, and during the washing process of storing textiles in a closed washing bag. It is characterized by functioning as a collecting means for synthetic resin fibers washed off from textile products that may be present.

Since the laundry bag provided according to the present invention is built into the textile product, the laundry bag can be suitably used in all the washing steps of the textile product. That is, the textile product to be washed may be simply housed in the washing bag built in the textile product and the washing bag may be closed, and then the environment for the washing bag and the textile product contained therein in the washing machine. It is possible to carry out a washing process in consideration of. In addition, the laundry bag is adapted to the textile product to be washed with it in terms of its size, especially volume, so that the laundry bag is always only the (minimum) size required to accommodate the textile product. It is preferable to have. However, it is also preferable to select the laundry bag to be (slightly) larger so that additional textile products / clothing, optionally containing synthetic resin fibers, can be accommodated during the washing process.

In addition, it is highly suitable to form the laundry bag from a thermosetting synthetic resin net structure having an average mesh width in the range of 5 μm to 200 μm. Experiments have shown that the use of such laundry bags can achieve a reliable collection effect of synthetic resin fibers washed off from textile products that reach a collection rate of approximately 100% on the one hand, and good washing on the other hand. The results were also shown to be achievable. It is preferred that a collection rate of at least 90% or at least 95% be achieved. By applying the thermosetting synthetic resin net structure according to the present invention, the synthetic resin fiber of the textile product that has normally flowed out into the environment is accurately adjusted to the required (average) mesh width for effectively collecting the synthetic resin fiber. Will be possible.

At that time, within the framework of the present invention, the average mesh width of the synthetic resin net structure can be adapted to the specific synthetic resin fiber used for the textile product, and therefore the mesh width of the synthetic resin net structure can be adjusted to, for example, the corresponding textile product. It is also preferable that the synthetic resin fiber can be selected according to the type and thickness of the synthetic resin fiber used therein. Therefore, for example, a washing bag having a small mesh width is used for textile products containing extremely fine synthetic resin fibers, and a washing bag having a larger mesh width is used for textile products containing thicker fibers. can do.

As mentioned above, the laundry bag is built into the textile product, so it is highly desirable to allow the laundry bag to be permanently fixed in or on the textile product in an appropriate manner, especially by sewing, but a laundry bag is required. Releasable fixation using appropriate fixing means (zippers, snap buttons, etc.) if required to be removable from the textile, depending on (eg, for separate use for washing another garment) Is also possible.

Irregular fluctuations during the washing process in the washing machine and the action of water pressure on the washing bag from the outside and inside contributes to the efficiency of the present invention. Due to the extremely smooth surface of the thermosetting synthetic resin net structure, the fiber fragments adhering to the inner surface of the bag are washed away by the inflowing and outflowing water, thereby preventing the formation of the filter cake. As a result, the stagnation pressure is reduced, the bag material that functions as a filter is kept clean, and high filter capacity is guaranteed.

According to the preferred configuration form of the present invention, when the textile product or clothing is used in an appropriate manner, the textile product or clothing is placed in an inconspicuous place in a manner that makes it invisible and not recognized by others. A laundry bag is placed.

Therefore, in the case of clothing, it is preferable to place the laundry bag on the inner surface of the clothing, in or on the lining, or in the area of the collar of the clothing.

Within the framework of the present invention, the laundry bag is further provided with a zipper that points to the inside or outside of the garment, and when the zipper is open, the garment is flipped over and stored in the internal space of the laundry bag through the zipper. It is preferable to be able to obtain and to be able to close the laundry bag containing the clothing with a zipper. It is clear that this makes the handling of the laundry bag according to the present invention practical. In addition, the laundry bag can be used as a kind of bag that can be closed by a zipper during use / transportation of the garment as needed by appropriately forming the garment.

According to the preferred configuration of the present invention, the average mesh width of the tissue used for the laundry bag is in the range of 5 μm to 100 μm, particularly about 50 to 80 μm, whereby the efficiency of the desired filtering action is good. Optimized while ensuring washing capacity at the same time.

The synthetic resin network structure used in the present invention is preferably a thermosetting polyamide, particularly polyamide 6.6 (PA6.6). According to this, a sustained heat resistance of 100 ° C. (wet) is particularly achieved, which is optimal for the application of the present invention. Of course, within the framework of the present invention, another material may be used as long as it is sufficiently stable under general ambient conditions during the washing process (particularly by machine).

Further, it is also effective to use a single fiber structure, which can be used as a monolayer on the other hand. The present invention uses a single-layer, single-fiber mesh structure made of PA6.6 having a structure thickness of about 80 μm, a tolerance of 50 μm ± 10% for each of the weft and warp mesh widths, and a net opening area of 27%. It turned out to be extremely suitable for.

As mentioned above, the washing bag can be closed in an appropriate manner, and therefore the closing tool of the washing bag should of course assist the collecting function, and therefore has a length of about 100 μm (or less) as described above. It is at least almost impermeable to synthetic resin fibers.

In addition, the laundry bag is also provided with a closure that also blocks synthetic resin fibers, particularly with a zipper that is appropriately fine (preferably substantially water resistant) and / or optionally blocked by a layer of the laundry bag. It is preferable that the can be closed.

However, as a preferred closing means, the laundry bag is rolled up in the area of the opening after accommodating the textile product to be washed, and then using a particularly suitable closing element (eg, a snap button provided on the reinforcement of the washing bag or It is also possible to close the opening provided on the edge side of the laundry bag by fixing it in a rolled-up state (using a zipper). As a result, it is possible to prevent the synthetic resin fibers collected in the washing bag caught in the area of the opening by a kind of labyrinth seal method from flowing out from the washing bag.

Next, the present invention will be described in detail below with reference to the accompanying drawings.
