[Effect] It is not necessary to iron each time after washing, and wrinkles do not occur even after washing about 20 times, and simple anti-wrinkle processing can be performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a simple and economical anti-wrinkle treatment for cotton clothing.

[0002]

2. Description of the Related Art The usage rate of cotton in cotton products or cotton blended products is as high as 40% or more of the total fibers, and it tends to increase more and more in the future. Under these circumstances, there is a problem that cotton products such as shirts are easily wrinkled, and many clothing manufacturers are trying to prevent wrinkles. Recently, anti-wrinkles such as VP processing, SSP processing and DA processing have been tried. Due to the development of processing technology, cotton products, which are characterized by being worn without iron after washing, are on the market.

[0003]

However, the above-mentioned products on the market are subjected to the wrinkle-proof treatment before they are put on the market, and the wrinkle-proof treatment cannot be performed at home. Therefore, at present, at home, ironing is carried out by spraying a mist to increase wrinkles, but wrinkles are generated by one washing, so ironing is performed each time.

If a cotton product can be easily subjected to a wrinkle-proof treatment at home, it can be worn without ironing each time it is washed, which saves labor and is economical. Therefore, the present invention eliminates the need to iron each time you wash,
It is an object of the present invention to provide a wrinkle-proof processing method capable of easily performing anti-wrinkle processing and an iron capable of the above-mentioned processing.

[0005]

In order to achieve the above object, the present invention uses a resin that directly cross-links with the cellulose of the cotton fiber, and uses an amorphous portion of the cellulose that causes wrinkles of the fiber. Is configured to reinforce, and wrinkles can be suppressed by this configuration.

[0006]

[Function] Using a heat-reactive water-soluble glyoxal resin,
A glyoxal-based resin aqueous solution is formed into a mist by a steam generator provided in an iron, sprayed onto clothes, and heat and pressure are applied while being dried with an iron, thereby applying glyoxal-based fibers between cellulose fibers. Since a cross-linking reaction with the resin occurs and the space between the cellulose is reinforced, the generation of wrinkles is suppressed, and the anti-wrinkle effect can be generated.

1 and 2 are schematic cross-sectional views of an iron with a wrinkle-proofing function according to an embodiment of the present invention, in which not only the wrinkle is extended by a heater, but also the iron is prevented at home. Wrinkle processing can be performed.

In FIGS. 1 and 2, reference numeral 1 is a container holding an aqueous solution of a wrinkle-preventing agent, and 2 is water used for steam generation. Reference numeral 3 is a valve that controls the amount of water output, and controls the amount of steam generated. 4 is a steam generating part, which utilizes heat of the heater 8. Reference numeral 5 is a nozzle for ejecting a steam, and 6 is a nozzle for sucking the processing agent aqueous solution. Reference numeral 7 is a mist, which sprays onto the clothes a mist of the aqueous processing agent solution that has been decompressed and pulled up by the steam. 9 is a temperature controller, and 10 is an iron handle. Reference numeral 11 is an electric pump or a manual pump.

Further, in FIG. 2, 11 is an electric pump or a manual pump, the spraying of the processing agent is performed by the electric pump or the manual pump, and the wrinkle-proof processing condition can be the same method as that shown in FIG. it can.

FIG. 3 shows a process chart of the wrinkle-proof processing method in the embodiment of the present invention.

First, an aqueous solution of a glyoxal resin as a wrinkle-preventing agent is placed in a container 1, the temperature of an iron is raised and water 2 is added to generate steam in a steam chamber 4 and jet it from a nozzle 5. By this, a decompressed state is created, and the processing aqueous solution is sucked up into fine water droplets, which are sprayed onto the clothes. The nozzle 5 has a structure in which the angle can be changed,
It is devised so that the sprayed state is properly irradiated to the clothes.

Next, the clothes uniformly sprayed with the aqueous processing agent solution are dried at a low temperature of 80 ° C. or lower, and then the temperature of the iron is raised to 160 to 190 ° C. to apply heat while stretching the wrinkles. It is possible to form a wrinkle-resistant state by directly cross-linking a certain glyoxal resin with cellulose which is the main component of the fiber.

The wrinkle-preventing effect and washing durability of the cotton product which has been subjected to the above-mentioned method will be described with reference to FIG. FIG. 4 shows the results obtained by changing the concentration of the glyoxal-based resin in the range of 3 to 20%. When the concentration of the glyoxal-based resin is 3%, the wrinkle-preventing effect is not so great, but the effect is sufficient in the range of 5% to 20%. It is within the usable range. On the other hand, if it exceeds 20%, although the anti-wrinkle effect is obtained, the clothes themselves become hard and uncomfortable to wear and cannot be used.

Also, the wrinkle-preventing effect remains after washing about 20 times, and it can be worn without ironing. However, if the effect is reduced, the same wrinkle-preventing treatment as described above is applied again to restore the original state. It can be used any number of times.

Furthermore, by adding 5% to 15% of a urethane resin, a silicone resin, or an ethylene resin to the glyoxal resin of the above-mentioned embodiment, it is possible to improve the feeling such as flexibility.

[0016]

EFFECTS OF THE INVENTION According to the method for preventing wrinkles of cotton clothes according to the present invention, the wrinkles can be easily treated at home and can be worn any number of times after washing the clothes without ironing. It is very convenient and energy saving. Further, the processing cost is low and it is economical because it can be worn 20 times or more in one treatment.
