Fiber structure

Technical field

The present invention relates to a fiber structure having water repellency, oil repellency and antifouling properties having excellent durability.

Background art

[0002] Conventionally, water repellency, repellency has been applied to fabrics made of synthetic fibers, natural fibers, and mixed fibers thereof.

As a method for imparting oiliness, many treatments of fabrics with fluorine-based compounds and silicon-based compounds are performed.

[0003] In recent years, consumer demands for water repellency and oil repellency have further increased, especially in the field of sports clothing such as wind wear, golf wear, ski wear, etc. In women's clothing such as blouses, slacks, and skirts, and in the uniform clothing field such as work clothes and uniforms, in addition to durable water and oil repellency, antifouling properties, especially stains on food and dirt that adheres to it, are removed by washing. The demand for easy things is increasing.

[0004] As a means for imparting washing-resistant water and oil repellency to fiber fabrics, a method of mixing an isocyanate compound (Patent Document 1), a method of treating with a isocyanate compound and then treating with a water repellent (Patent Document 2), a method of treating with a compound containing a polymerizable vinyl group and a condensable methylol group (Patent Document 3), after treatment with an aqueous fluorinated water / oil repellent, and a solvent-based fluorinated water / oil repellent. Examples include a method of treating with an oil (Patent Document 4) and a method of improving wear resistance during washing (Patent Document 5), but V and slippage are insufficient in washing durability and antifouling properties. Proposal of what has both, has been made.

[0005] In addition, water repellency and oil repellency are often required for swimsuits (Patent Documents 6 and 7). In particular, swimsuits for swimming are aimed at low resistance, and general swimsuits have low water resistance. It is intended to reduce health energy loss due to wettability. However, when wearing a swimsuit on a sandy beach, etc., swimsuits that are not water repellent or swimsuits that are water repellent but have low water repellency If the swimsuit and Z or sand get wet, the sand will adhere to the swimsuit, causing problems in appearance, and part of the sand will temporarily adhere to the gaps in the woven or knitted fabric. There are problems such as being stuck in and not being able to be removed by washing, but there are no proposals focusing on this problem.

[0029] The fiber structure of the present invention has water repellency after 20 washings of grade 4 or higher and oil repellency of grade 4 or higher. A state in which the organic fluoride compound is contained in the resin together with the triazine ring-containing compound by adhering through the resin coating, such as a triazine ring-containing compound that does not directly adhere to the fiber alone. In addition, the durability of washing with organic fluorine compounds is greatly improved by being fixed to single fibers, and the water and oil repellency is 4th grade or higher after 20 washings. It is shown.

[0030] Further, the film thickness of the triazine ring-containing compound-containing resin film is 5 to: LOOnm, and since it has a thin film structure, it is possible to further prevent the resin from falling off by washing and to improve washing durability. This is a significant improvement. Because of such high water and oil repellency, the fiber structure of the present invention exhibits excellent antifouling properties.

[0031] The fiber structure of the present invention has a soiling property of food stains after 20 washings, that is, it is difficult to attach 3 Grade and above, washability is grade 3 and above. Organic fluorinated compound and triazine ring-containing compound are uniformly formed on the fiber, and water and oil repellency after washing 20 times has the performance of grade 4 or more. It also exhibits excellent performance against contaminated food stains with a contamination level of 3 or higher and a laundry removal level of 3 or higher.

[0032] Further, the fiber structure of the present invention has a stain resistance of the ink-stained soil after 20 washings, that is, the hard-to-attach strength S3 or higher and the laundry removal power or higher. Ink juice contains glue and carbon, in addition to carbon, and has a property of being easily attached and difficult to fall off. However, similar to the above, an organic fluoride compound and a compound containing a triazine ring are used. A uniform film is formed on the fiber, and it has a water repellency and oil repellency level of 20 or more after washing. It exhibits performance that is above the grade.

[0034] When the fiber structure is worn as a swimsuit on a sandy beach, for example, the adhesion of sand is small, and the performance of the water repellency after washing 20 times or more is improved. The adhesion preventing effect can be improved. In addition, considering the adhesion of the sun oil wrapped in sun oil and the sun oil itself in the swimsuit, it is necessary to have high oil repellency. The fiber structure of the present invention also has oil repellency of grade 4 or higher after 20 washings. Therefore, it is possible to obtain a fiber structure having a sand adhesion preventing property of grade 3 or higher. Therefore, the fiber structure of the present invention is suitably used as a swimsuit.

[0035] Further, the mud dirt removing property after 20 washings of the fiber structure of the present invention is 4th grade or more. Mud is often rubbed in water and oil in daily life and sports. In such a case, in the present invention, the coating using the organic fluorine-based compound and the triazine ring-containing compound is uniformly formed on the fiber, and the water repellency and oil repellency strength after washing 20 times or more are higher. It is possible to prevent mud stains from directly adhering to the fiber, and it is possible to improve the anti-stain property of mud stains, and to obtain a fiber structure with a removability of grade 4 or higher.
