Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on the production of breathable, moisture-permeable and waterproof fabrics, and is based on the use of yarns that are used in the production of breathable, moisture-permeable, and waterproof fabrics. A yarn for use in breathable wet waterproof fabric, characterized in that it is a yarn consisting of lower fibers, and the surface of each of the fibers is coated with a film containing a fluorine-containing compound. □ ・In recent years, 4X, moisture-permeable, waterproof products have been developed in the market for new clothing.Many of them are made by laminating a synthetic resin film with micropores onto fabric. In both cases, ηhg is integrated into the fabric and film or the fabric. As it is a product with a high density, it is not good enough for 9 products.In order to improve this defect, fucaine denier fibers are woven and woven to a bulk density to make them water repellent and processed 1. (Additional calendar processing if necessary) The method of □ is attracting attention, but the fibers that make up the fabric! Since the gap 1 is necessarily small, it is difficult to coat the water repellent agent uniformly on each paper, making it waterproof.

The current situation is that the problem of not being able to maintain a balance between groove permeation performance and texture has arisen, and the situation has not yet reached a stage where it is fully satisfactory. ′
□ □ The present inventors □ have developed a fabric from this situation.

#i made of polyvinyl chloride, polyvinylidene chloride, etc.
It is a li fiber, and the single filament diameter of 'f: must be 10/l or less, preferably 9μ or less. This is because fibers thicker than 10μ often lack waterproof effect when formed into a fabric, but in the case of a two-circle cross section, polyethylene terephthalate has a thickness of about 1d or less, and nylon 6 has a thickness of about 0.8dl.
! Corresponds to the bottom.

It should be noted that the fibers of the present invention are of course not limited to conventional circular cross-section fibers, but can also include hollow or irregularly shaped fibers.
11 1, there may be a chi, and its r゛equivalent diameter' is included! In general, it is sufficient if it is less than 10 μm'J.

Next, in the present invention, the fluorine-containing compound refers to a fluorinated α-substance which is usually used as a water- and oil-repellent imparting agent for textile products, but a polymer made from a heavy compound represented by the following general formula is suitable. .

It may also be copolymerized with other polymerizable monomers to improve oil repellency, flexibility, adhesion, etc.

The present invention is characterized in that the surface of each of the fibers forming the thread is coated with a film of a fluorinated metal, and the fibers in such a shape can be formed by any method. II'
! (a), but after applying a liquid containing a fluorinated metal substance to an undrawn fiber thread, drawing the thread and heat-fixing the fluorine-containing compound are applied simultaneously or separately. (The heat fixing treatment may be performed after 1ml of weaving) has the effect of obtaining fibers coated with a fluorine-containing compound directly from undrawn fiber yarns, as well as excellent adhesion between the skin l111 and the fibers. This method is particularly recommended because of its advantages. The film of the fluorine-containing compound formed on the C fibers should preferably have a fluorine content of 15% by weight or more, preferably 20% by weight, and the amount of the film is determined based on the fiber.

It is preferable that the amount of Ii is 15% or more.

Of course, these amounts will vary depending on the type of fiber and the required properties.

The C value is adjusted as appropriate depending on the application.

The yarn of the present invention has high density by using all or part of this! I
By using IRfa weave, we provide a product that has excellent wind and breathability, moisture permeability, and waterproof properties.

Hereinafter, the present invention will be described in more detail with reference to Examples. The air permeability and moisture permeability + #J water pressure t1]1 constant of the fabric was determined by the following method.

As is clear from this table, the fiber yarn of the present invention has an air/moisture permeability of 1 (b), which is extremely suitable for the production of water woven fabric.

In addition, the fabrics of Examples 1 to 7 also had a surface resistance C of post-processed products (2S made of polyethylene prephthalate fibers).
It is extremely supple and durable compared to high-density tuff (water-repellent treated). child.
