Problems solved by technology

However, when wearing swimwear on the beach, etc., if the swimwear and / or the sand are wet, the sand will adhere to the swimwear, and the appearance In addition, some sand does not just adhere temporarily, but penetrates into the gaps in the fabric, causing problems that cannot be removed even if it is washed. There is no proposal that focuses on this problem.

Embodiment 1～7、 comparative example 1～6

[0107] Using 84dtex, 72F twisted textured yarn made of polyethylene terephthalate for warp and weft, it was woven into a plain weave, and then the fabric was passed through an opensoaper type continuous refiner at a temperature of 95°C Refined, washed with hot water at 60°C, washed with water, dried at 130°C, dyed light yellow at 130°C by flow dyeing, washed with hot water, dried at 130°C, The setting was performed with a pin tenter at a temperature of 170° C. to obtain a fabric having a warp density / weft density of 138 / 90 pieces / 2.54 cm. This dyed fabric was subjected to the following fiber surface coating treatment and organic fluorine-containing compound treatment, and the properties of the obtained fabric were evaluated, and the results are shown in Table 1.

Abstract

The invention stably provides a fiber structure having excellent washing durability, water / oil repellency and antifouling properties. A fiber structure characterized in that each of the single fibers used in it is covered, on the surface thereof, with a resin film containing an organic fluorochemicals via a resin film containing a triazine ring-containing compound or containing an organic fluorochemicals and a triazine ring-containing compound, and that said fiber structure has a water repellency level of grade 4 or higher and an oil repellency level of grade 4 or higher after 20 times of washing.

Description

technical field [0001] The present invention relates to a fibrous structure having hydrophobicity, oleophobicity and antifouling properties excellent in durability. Background technique [0002] Conventionally, as a method for obtaining hydrophobicity and oleophobicity for fabrics formed from synthetic fibers, natural fibers, and their blended fibers, a method of treating fabrics with fluorine-based compounds, silicon-based compounds, and the like has been widely performed. [0003] In recent years, consumers have higher requirements for hydrophobicity and oleophobicity, especially in the field of sports clothing such as windproof clothing, golf clothing, ski clothing and other sports clothing, there is a strong demand for fabrics with excellent cleaning durability. In the field of women's clothing and uniform clothing such as work clothes and professional wear, not only durable hydrophobicity and oleophobicity, but also antifouling properties, especially antifouling propert...
