Description

本発明は、軽量性に優れた透湿防水性布帛および該透湿防水性布帛を用いてなる繊維製品に関する。   The present invention relates to a moisture-permeable and waterproof fabric excellent in lightness and a fiber product using the moisture-permeable and waterproof fabric.

従来、スポーツ衣料やユニフォーム衣料などに使用されている透湿防水性布帛において、透湿性および防水性を備えた樹脂製の薄膜が広く使用されている。例えば、織編物などの基布に、多孔質または無孔質ポリウレタンをコーティングしたものや、ポリウレタンなどの多孔質または無孔質樹脂製フィルムを接着剤により基布にラミネーションしたものなどがある。多孔質樹脂製薄膜はその孔の大きさにより、また、無孔質樹脂製薄膜の場合は孔が無いものの吸湿性物質を含有することで親水性とし、雨やその他の水を通さず、湿気(水蒸気)を通すことにより透湿防水性を呈している。   Conventionally, in a moisture-permeable and waterproof fabric used for sports clothing, uniform clothing, and the like, a resin thin film having moisture permeability and waterproof properties has been widely used. For example, a base fabric such as woven or knitted fabric is coated with porous or nonporous polyurethane, or a porous or nonporous resin film such as polyurethane is laminated on the base fabric with an adhesive. Porous resin thin films are made hydrophilic by the size of their pores, and nonporous resin thin films do not have pores but contain hygroscopic substances so that they do not pass rain or other water. Moisture permeable and waterproof properties are exhibited by passing (water vapor).

これらの従来の透湿防水性布帛では、肌や内側の衣服との磨耗から透湿防水層を保護するため、透湿防水層の上にさらにトリコットや織物を積層する方法が採用されている(例えば、特許文献1参照)。しかしながら、かかる透湿防水性布帛では、生地が重くなるため着用快適性が損なわれるという問題があった。   In these conventional moisture permeable waterproof fabrics, a method of further laminating a tricot or a fabric on the moisture permeable waterproof layer is employed in order to protect the moisture permeable waterproof layer from abrasion with the skin and inner clothes ( For example, see Patent Document 1). However, such a moisture-permeable and waterproof fabric has a problem that wearing comfort is impaired because the fabric becomes heavy.

本発明の透湿防水性布帛において、基布の片面に積層される透湿防水層としては、透湿性を有するウレタン樹脂からなるフィルム、ウレタン樹脂コーティング、アクリル樹脂コーティング、ポリテトラフロロエチレン樹脂フィルム、ポリエステルフィルムなどがあげられが限定されるものではない。特に、ケミカルリサイクル処理により再度ポリエステルの原料として再生可能であり何度でもリサイクル使用できる点で省資源かつ環境保全できる点より、より好ましくは無色透明のポリエステルフィルムであるほうがよい。  In the moisture permeable waterproof fabric of the present invention, as the moisture permeable waterproof layer laminated on one side of the base fabric, a film made of urethane resin having moisture permeability, urethane resin coating, acrylic resin coating, polytetrafluoroethylene resin film, Examples include, but are not limited to, polyester films. In particular, a colorless and transparent polyester film is more preferable from the viewpoint that it can be recycled as a raw material of polyester again by chemical recycling treatment and can be reused any number of times, thus saving resources and protecting the environment.

かかるポリエステルフィルムとしては、ポリエーテル−エステル系エラストマーやPBT(ポリブチレンテレフタレート)からなるポリエステルフィルムが好適に用いられる。また、上記フィルムは透湿性を有するが、該フィルムは多孔質でもよいが、透湿性を有するポリエステルを主成分とする無孔質フィルムであることが好ましい。多孔質フィルムである場合、無色透明にはなり得ないからである。ポリエステルに透湿性を付与するには、特に限定されるものではないが、ポリエチレングリコールなどの吸湿性材料をポリエステルに共重合する方法が好適に用いられる。   As such a polyester film, a polyester film made of a polyether-ester elastomer or PBT (polybutylene terephthalate) is preferably used. Moreover, although the said film has moisture permeability, this film may be porous, but it is preferable that it is a nonporous film which has polyester which has moisture permeability as a main component. This is because a porous film cannot be colorless and transparent. To impart moisture permeability to the polyester, although not particularly limited, a method of copolymerizing a hygroscopic material such as polyethylene glycol with the polyester is preferably used.

上記ポリエーテル−エステル系エラストマーは、長鎖エステル単位および短鎖エステル単位からなり、該短鎖エステル単位は、全ポリエーテル−エステル系エラストマーの30〜70重量%の範囲にあることが好ましい。上記短鎖エステル単位の割合が、30重量%未満であるポリエーテル−エステル系エラストマーは比較的低融点であって、加工性が不良であり、また、該短鎖エステル単位が、70重量%を超えるポリエーテル−エステル系エラストマーの場合には、比較的高融点であり、加工性が不良である。   The polyether-ester elastomer is composed of a long-chain ester unit and a short-chain ester unit, and the short-chain ester unit is preferably in the range of 30 to 70% by weight of the total polyether-ester elastomer.

Alternatively, it can be obtained by removing the solvent by a wet method. It is preferable that such a polyether-ester elastomer is coated on at least a part of one side of the fabric, or a film made of a polyether-ester elastomer is laminated on at least one side of the base fabric. . It is preferred that such a sintered-ester elastomer is coated on at least a part of one side of the fabric, or a film made of a sintered-ester elastomer is laminated on at least one side of the base fabric.

エチレンホルマールを用いる場合は、該ポリエーテル−エステル系エラストマーを2〜30重量%、好ましくは、5〜20重量%の範囲で使用して、50〜60℃の温度でエチレンホルマールに溶解させ溶液を調合する。 When ethylene formal is used, the polyether-ester elastomer is used in the range of 2 to 30% by weight, preferably 5 to 20% by weight, and dissolved in ethylene formal at a temperature of 50 to 60 ° C. to prepare a solution. Formulate. Solvents in which the polyether-ester elastomer can be dissolved include dimethylformamide, dioxane, ethylene formal, toluene, chloroform, methylene chloride, or two or more organic solvents. In view of the above, it is most preferable to use ethylene formal. Solvents in which the sintered-ester elastomer can be dissolved include dimethylformamide, dioxane, ethylene formal, toluene, chloroform, methylene chloride, or two or more organic solvents.

Mix.

また、布帛上にコーティングする方法としては、通常のコーティング法、例えば、ナイフコーター等を用いて行えばよいが、コーティングの量としては、コーティング層が5〜50μm、好ましくは、10〜20μmの範囲となるように行えばよい。該コーティング層が5μm未満の場合には、均一な皮膜を形成することが困難であり、また、50μmを超える場合には風合として弾性が強くなり、また、透湿性も低下するので好ましくない。   Moreover, as a method of coating on the fabric, a normal coating method, for example, a knife coater or the like may be used, but the amount of coating is 5 to 50 μm, preferably 10 to 20 μm. It can be done so that If the coating layer is less than 5 μm, it is difficult to form a uniform film. If the coating layer exceeds 50 μm, the elasticity becomes strong and the moisture permeability decreases, which is not preferable.

It is preferable to use a uniform film. When the thickness of the film is less than 2 μm, the laminating operation becomes difficult and there is a possibility that uniform water pressure resistance may not be obtained, and the strength of the moisture permeable waterproof layer is significantly reduced. If the thickness exceeds 30 μm, the moisture permeability may be lowered, and the bending hardness of the waterproof and moisture-permeable layer becomes hard, so that the entire fabric becomes hard.
