Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing method for applying a size to a textile product that is durable against washing.

Sizing processing of textiles has been very common since ancient times.In the case of Tonto, a water-soluble sizing agent is used, so it takes 2 washes/! The glue falls off at -. Therefore, at the consumer level, starching is applied as needed when washing at home or at a laundry shop. The inventor of the present invention has conducted intensive research to improve the washing durability of the adhesive by improving the shortcomings of the sizing process, and as a result, has made the sizing agent insoluble in water after the sizing process. discovered that washing durability of the mesh side could be obtained and arrived at the present invention.

That is, in the present invention, a water-soluble sizing agent is applied to a textile product, and then a rare gas, 1-tonium chloride, is reduced in pressure to 0.1 to 5 Torr.

This is a sizing method for textiles, which is characterized by cold plug processing using nitrogen or a mixture of two or more of these gases.

The present invention will be explained in detail below. In the present invention, first, a water-soluble sizing agent (-1) is applied to the textile product to be treated.

The method of the present invention applies to all types of fiber products, including knitted items, woven fabrics, secondary products, and yarns, regardless of whether they are natural fibers or synthetic fibers, long fibers or short fibers, etc. can.

In the present invention, starches (wheat starch, rice flour, corn starch, zago starch, halet starch, tapioca starch, etc.) are used as the water-soluble sizing agent.

Modified starches (dextrin, pritish gum,
Apalatin, carboxymethyl starch, etc.) 2 fibers!
Derivatives (methyl cellulose, ethyl cellulose, hydroquine ethyl cellulose, carboxyl methyl cellulose, etc.), synthetic glues (borichinyl alcohol, polyacrylic acid, etc.), etc. are used.

It is possible to use these glues alone or in mixtures. No special method is required to apply the adhesive, and a commonly used method may be used.

In the present invention, the fibrous product to which the sizing agent is applied is
Processing is performed using low-temperature plasma of a rare gas, oxygen, nitrogen, or a mixture of two or more of these gases at a reduced pressure of Torr.

The low temperature plasma used in the present invention has a Q higher than 1 Torr, 5 Torr or less, 1 preferably 0.2 Torr or more, 4
High frequency (e.g. 13
．． 56 MHz). Low-temperature plasma has a gas decompression degree of 0.1T.
If it is less than orr, the processing effect is poor. If it is more than 5 Torr, the plasma generation becomes unstable, so it is necessary to perform the treatment in the range of Q, from 11'orr to 5 Torr. The gas used for plasma generation must have the ability to cause a crosslinking reaction in the glue.5 Examples of gases that have this ability include rare gases, oxygen, nitrogen, and mixtures of two or more of these gases. . When treated with such low-temperature gas plasma, the size applied to the textile is cross-linked, and even when the textile is washed, the size does not fall off and the original texture can be maintained for a long time. Moreover, the products after this low-temperature plasma treatment have high hydrophilicity, so dirt can be easily removed and dirt is difficult to re-adhere during washing, that is, SR performance (Soil
It also has release properties and antifouling properties. Since the plasma crosslinking properties of glues vary depending on the glue used, it is advisable to change the treatment conditions during plasma treatment depending on the glue used. For example, starch is relatively easy to cross-link, but povinyl alcohol is slightly cross-linked. Therefore, when using polyhinyl alcohol as a sizing agent, it is necessary to make the irradiation conditions stronger than for starch.

The method of the present invention focuses on the fact that when a water-soluble sizing agent is irradiated with plasma, network crosslinks are formed between the sizing agent molecules, making the sizing agent insoluble in water, and this is applied as a permanent sizing process for textile products.

The present invention has the above-mentioned configuration.According to the present invention, permanent sizing of textile products can be carried out extremely easily, and its industrial utility value is greater than that of non-electronic products.

Hereinafter, the method of the present invention will be explained in more detail with reference to examples, and the texture of the treated fabrics in the examples will be evaluated by Total Hunt (the sum of the front and back surfaces of the treated fabric using a texture meter manufactured by Ninoyama Kiko). The water absorption was measured using the JIS-L-1096 Hylenox method, and one drop of SR B heavy oil was added, and the stains were removed after being left overnight and washed using the JIS-L-0217 103 method (home washing method). The severity was judged on a five-level scale from grade 1 (bad) to grade 5 (good).
