Definitions
- the present invention relates to a method for treatment of a textile, and a treated textile. More particularly, it relates to a method for treatment of a textile, which method maintains durable water- and oil-repellency even after long-term use including the washing and the like and further maintains a touch, a feeling and a flexibility of fiber itself, by a modification treatment of the textile.
- a fluorine-containing compound having a fluoroalkyl group gives excellent water- and oil-repellency to a textile.
- an acrylic polymer treating agent having a fluoroalkyl group has been practically used.
- a touch, a feeling and a flexibility of the treated textile are remarkably deteriorated and the resultant water repellency is remarkably deteriorated by the washing or abrasion.
- a combined agent has been used on the treatment, together with the acrylic polymer having the fluoroalkyl group.
- Examples of combined agent include a melamine resin, a urea resin and the like.
- these resins are used in combination, the durability is improved in comparison with the case when using the polymer alone, but the touch, feeling and flexibility of fiber itself are liable to be deteriorated. Accordingly, it can be said that the durability and the touch, feeling and flexibility of fiber itself are contrary each other when using the fluorine-containing polymer.
- Japanese Patent Kokai Publication No. 98568/1993 discloses that animal hair fibers are treated with an alkylphosphate salt to impart the water repellency and flexibility to the animal hair fibers. However, the treated fibers are inferior in durability because they are not treated with a fluorine-containing water- and oil-repellent.
- a chromium complex of carboxylic acid has also been used as a processing agent for a textile or paper for the purpose of imparting a water repellency.
- a chromium complex of carboxylic acid having a perfluoroalkyl group has been used for the purpose of imparting an oil repellency in addition to the water repellency (cf. Japanese Patent Kokoku Publication Nos. 466/1958 and 3274/1969).
- an effect of these chromium complexes is not always sufficient, and a further enhancement in effect has been required.
- An object of the present invention is to maintain a durable water- and oil-repellency even after long-term use including the washing and the like, and to maintain a touch, a feeling and a flexibility of fiber itself even after the treatment of textile.
- the present invention provides a method for treatment of a textile, which comprises:
- the present also provide a textile treated by the above method for treatment.
- treatment means that a textile is contact with a treating liquid containing the modifier, the fixing agent, the metal complex or the fluorine-containing water- and oil-repellent.
- the treatment may he conducted, for example, by an immersion, an impregnation, a pad method, a coating method and the like.
- the textile may be treated with the modifier after treated with the fixing agent.
- a textile may be treated with the fixing agent after treated with the modifier.
- the modifier used in the first stage of treatment is the phosphoric acid derivative represented by the above general formula (I) or the salt thereof.

- a temperature of the acid solution is usually from 5 to 90°C, preferably from 20 to 70°C.
- An immersion time in each of the fixing agent solution, the modifier solution and the acid solution is usually at least 10 seconds, preferably from 1 to 120 minutes, more preferably from 1 to 30 minutes.
- a retention time in the bath adjusted to the pH of 1 to 5 is usually at least 10 seconds, preferably from 1 to 30 minutes.
- a drying temperature is usually from 10 to 70°C, preferably room temperature.
- the drying time varies depending on the drying condition (particularly, the drying temperature), but is usually within 24 hours, preferably from 0.1 to 10 hours.
- a weight ratio of the fixing agent to the modifier in the bath is usually from 0.1:1 to 10:1.
- a carboxylic acid-metal complex is obtained by reacting the metal salt compound with the carboxylic acid.
- a chromium complex is obtained by reacting a carboxylic acid with a chromium compound.

- a drying temperature can be adjusted within the range from 10 to 140°C, but it is practically sufficient to air-dry at room temperature.
- the aqueous solution may contain an acid.
- the acid include mineral acids such as hydrochloric acid and sulfuric acid and organic acids such as formic acid, acetic acid and propionic acid.
- the textile which has already been subjected to the first stage of treatment is treated with a usual fluorine-containing water- and oil-repellent as described hereinafter, in the second stage (B) of treatment.
- the method may be a method which has hitherto been used.
- the treatment is conducted by an immersion, a pad method, a coating method or the like, followed by drying.
- the combined agent such as the melamine resin and the urea resin may be used in combination.
- a heat treatment, a calendering and the like may be conducted.
- a treating agent e.g. a silicon compound

- a water-soluble lower alcohol or ketone isopropyl alcohol is particularly preferred
- an amount of 0.1 to 10% by weight preferably from 1 to 5% by weight based on the emulsion, in view of penetration of the fluorine-containing water- and oil-repellent.
- the second stage of treatment can be applied to any textile.
- a resultant carpet or fabric
- the second stage of treatment can be conducted on raw yarns or raw hairs used for the carpet, and the carpet can be produced by using the treated raw yarns or raw hairs.
- the raw yarns and raw hairs may be subjected to the first stage of treatment and then the resultant carpet may be subjected to the second stage of treatment.
- the water- and oil-repellency is obtained only at the surface of the textile fabric because the phosphoric acid derivative or carboxylic-metal complex is penetrated into the interior of a fiber bundle and then fixed. It is possible to impart the advantageous effect in the interior of textile even if the textile has a large thickness. Since the second stage of treatment is further conducted by using the fluorine-containing water- and oil-repellent, the durability becomes stronger. When using the phosphoric acid derivative, the deterioration of the feeling and flexibility of the textile which has not hitherto been avoided by using the fluorine-containing water- and oil-repellent alone, is improved surprisingly.
- the textile to be treated includes a yarn, a woven fabric, a knitted fabric, a nonwoven fabric, an artificial leather and the like which are formed from the fiber, in addition to the textile having the form of the fiber as such.
- the fiber there can be used chemical fibers including synthetic fibers such as polyester and nylon in addition to natural fibers such as cotton, wool and silk. It is also possible to use a textile blend of natural fibers and synthetic fibers.
- the woven fabric and artificial leather comprising superfine fibers, which have recently been remarkably developed, are suitable for the present invention in view of the fact that the feeling and touch are considered to be important.
- the superfine fibers usually have a fineness of not more than 1 denier, preferably not more than 0.8 denier, more preferably from 0.8 to 0.0001 denier, most preferably from 0.1 to 0.001 denier.
- the textile obtained by the present invention has the above excellent advantages and, therefore, it is suitably used for applications where water and oil repellency as well as stainproofing properties are required.
- the textile which is suitable for the present invention may be, for example, a carpet.
- the material of the carpet may be a polyamide such as nylon, a polyester, an acryl, a wool and the like, and is not specifically limited.
- the present invention is particularly effective for a nylon carpet which is usually used under a severe condition.
- the structure, the weaving type, the pile length of the carpet are not specifically limited.
- the textile obtained according to the present invention can be used for outdoor applications exposed to rainwater.
- Examples thereof include a tent, an automobile cover, a motorbike cover, a hood for rear deck of track, a coated sheet for construction, an umbrella and clothes (particularly, rainwears such as a raincoat and a poncho).
- the present invention can be used for the textiles used for a cover of a cap, a foot wear (e.g. shoes, slippers), a bag, a pouch or a seat (e.g. a car seat, a seat, a sofa and a chair), interior goods such as a curtain, a carpet, a wall and ceiling of buildings and vehicles (e.g. an automobile, a train, an aircraft and a ship) and various displays.

- Example 2 (in case (ii) that the treatment is conducted using a carboxylic acid-metal complex)
- a fabric consisting of superfine fibers (Artificial Leather SOFRINATIAL (trade name) manufactured by KURARAY CO., LTD) was immersed in an aqueous solution (bath ratio: 250%) containing 2% (solid content) of a perfluoroalkyl group-containing carboxylic acid-chromium complex (SCOTCHGUARD 233A manufactured by 3M CO.) of the formula: and 0.4% of formic acid and then subjected to a rotating treatment at 40°C using a dyeing test machine (manufactured by TSUZII SENKI KOGYO CO., LTD.) for 30 minutes. After swish off of water, the fabric was squeezed so that a wet pickup was 80%, and then the fabric was air-dried at room temperature.
- a perfluoroalkyl group-containing carboxylic acid-chromium complex (SCOTCHGUARD 233A manufactured by 3M CO.) of the formula: and 0.4% of formic acid
- a fluorine-containing water- and oil-repellent (TEXGUARD TG-520 manufactured by DAIKIN INDUSTRIES, LTD.) was diluted with tap water so that a solid content was 1%. Further, 2% of a blocked isocyanate (ELASTRON BN-69 manufactured by DAIICHI KOGYO SEIYAKU CO., LTD.) as a combined agent, 0.2% of a catalyst (ELASTORON CATALYST manufactured by DAIICHI KOGYO SEIYAKU CO., LTD.) and 3% of isopropyl alcohol were added to prepare a treating liquid.

- Example 2 The textile sample used in Example 2 was subjected to only the same treatment as the second stage of treatment used in Example 2, except that the solid content of the fluorine-containing water- and oil-repellent in the liquid was increased to two times that of Example 2. The feeling, water repellency, oil repellency, water absorption property and water resistance before and after washing were measured. The results are shown in Table 6.
- Example 2 The textile sample used in Example 2 was subjected to only the same treatment as the first stage of treatment used in Example 2, except that the solid content of the carboxylic acid-chromium complex in the solution was increased to two times that of Example 2.
- the feeling, water repellency, oil repellency, water absorption property and water resistance before and after washing were measured. The results are shown in Table 6.
- Example 2 L0 100+ 4 5.3 150 L20 70 1 6.8 112 Com.
- Ex. 3 100+ 4 10.6 109 L20 50 0 72.6 79 Com.
