法に関する。TECHNICAL FIELD The present invention relates to a method for producing a cloth having water and oil repellency. More specifically, it relates to a process for producing a cloth having excellent water-repellent and oil-repellent fabric, which is excellent in processing stability and is treated with a fluorine-containing water- and oil-repellent agent containing an organic solvent.

る。It has been widely known that a water-repellent and oil-repellent property can be imparted by treating a fiber material with a fluorine-containing water- and oil-repellent agent containing water as a dispersion medium. However, when naturally dried, there was a problem that the water repellency was significantly reduced. Further, it is widely known that a fiber material can be treated with a fluorine-containing water / oil repellent agent using an organic solvent as a solvent to impart durable water / oil repellent performance, for example, JP-A-5-302271. Has been proposed by.

鎖アルコール、炭化水素、植物油は消泡効果が小さく、
効果を出すためには添加量のアップが必要で、撥水撥油
性能の低下は免れない。However, when fibers are treated with a treatment liquid containing a fluorine-containing water and oil repellent agent using an organic solvent as a solvent,
A large amount of foam is generated in the treatment liquid, and the foam adheres to the fabric and dries, resulting in a partial increase in the amount of the fluorine-containing water and oil repellent agent attached, causing spot-like stains, and improving the surface quality of the fiber material. There was a problem of significantly lowering it. On the other hand, as a method for suppressing the generation of bubbles in a treatment method using a water and oil repellent agent using an organic solvent as a solvent, an antifoaming agent is generally used together.
Examples of the defoaming agent include long-chain alcohols, hydrocarbons, vegetable oils, alkylpolysiloxanes, etc., but long-chain alcohols, hydrocarbons and vegetable oils have a small defoaming effect,
In order to bring out the effect, it is necessary to increase the amount added, and it is unavoidable that the water / oil repellency is deteriorated.

いう問題があった。In general, even if an alkylpolysiloxane having a high defoaming effect is used, the defoaming effect is small with a treatment liquid containing a water and oil repellent agent using an organic solvent as a solvent. Therefore, there is a problem that not only the water and oil repellency is deteriorated, but also the seam slippage and the anti-snag property of the cloth are deteriorated, and the texture has a slimy characteristic peculiar to silicone.

Defoaming agent containing a fluorine compound obtained by emulsifying 5 parts by weight, 94.5 parts by weight of toluene, and 2 parts by weight of a perfluoropolyether compound with 2 parts by weight of a nonionic surfactant in an n-heptane solution. After being dipped in a treatment liquid consisting of parts by weight, and then uniformly squeezed with a nipple roll to a squeezing rate of 60%, the fluorinated water repellent was dried in a hot air dryer at 160 ° C for 3 minutes. A fabric was obtained in which the active ingredient was adhered to the fabric by 0.50% in solid content.

It processed like Example 2. Table 2 shows the results of the water repellency, oil repellency, and surface quality of the fabrics of Examples 1 and 2 and Comparative Examples 1 to 4. Regarding the foaming property, the treatment liquid containing the water and oil repellent agent using the organic solvent of Example 1 and Comparative Examples 2 and 3 as a solvent was used, and the dyed taffeta obtained in Example 1 was used as the test piece. The evaluation was performed and the results are shown in Table 3.

It was excellent in processing stability. In the second embodiment,
By performing the water / oil repellent treatment using water as a dispersion medium before the water / oil repellent treatment using an organic solvent as a solvent, a fabric having water / oil repellency with further improved durability can be obtained. It was
