レスのような熱処理が不可欠であった。However, even with this excellent performance, there is a significant decrease in water and oil repellency when wearing on children, and in order to bring out this performance again, conventional methods such as ironing and heat pressing have been used. Heat treatment was essential.

の都度面倒なものである上K。This is due to a structural problem with the fluorine thread water and oil repellent, and rearrangement of the fluorofurkyl groups or fluorofurkyl groups is required to fully develop water and oil repellency. However, for consumers who actually use water- and oil-repellent textiles, ironing them after washing is a hassle.

不要な撥水・撥油処理方法の開発が待たれている。Items with complex shapes may be difficult to iron (for example, clothing made of pile fabric with piles on the surface), and some items, such as diaper covers, are not normally ironed. The development of a water and oil repellent treatment method that does not require ironing is awaited.

A desirable example is - to 1% owf. If the amount of each used is less than this, the durability of the water repellent effect will be poor, and if it is more than this, problems such as a hard texture will occur, which is not preferable.

の被膜強化が行われる。(51 Effect of the Invention) The water repellency of woven and knitted fabrics that are treated with a fluorine water and oil repellent is reduced by washing when washed. This is thought to be due to disordered arrangement.In order to prevent such disordered arrangement of fluorofurkyl groups or fluoroalkylkenyl groups due to washing,
The coating of fluorine-based water and oil repellents is strengthened using ethyleneimine compounds.

。In the method of the present invention, the durability is dramatically improved by using a melamine compound in addition to a fluorine water/oil repellent and an ethyleneimine compound. That is, in the method of the present invention, the fluorine-based water and oil repellent is crosslinked with an ethyleneimine compound and a melamine resin, so that the fluorine-based water and oil repellent polymer is maintained in an extremely strong structure. Although it is thought that the purpose is to prevent the arrangement of fluoroalkyl groups or fluoroalkylkenyl groups from being disturbed by washing (Example 1), filament yarns made of polyethylene terephthalate (
75de/36f + S twist 300T/M) was used for the warp and weft, woven into a plain tuck fabric, and the temperature was 70℃.
After scouring and relaxing for 20 minutes at a temperature of 180°C, and setting the temperature for 1 minute at a temperature of 180°C, high-temperature dyeing was performed at a temperature of 130°C for 45 minutes using a 1-bath reducing agent (Bisnol P70).
Reduction cleaning was performed using 9/1 at a temperature of 80° C. for 20 minutes.
