Abstract
Description
本発明は着用時に圧迫力が加わる弾性ストッキングに関する。 The present invention relates to an elastic stocking to which a pressing force is applied when worn.
下肢静脈流の還流を改善するのに弾性ストッキングが用いられている。
また、リンパ浮腫における圧迫療法の１つとして医療用弾性ストッキングが用いられている。
静脈血やリンパ液を心臓方向へ流れやすくするために、この弾性ストッキングは足首の圧迫圧が一番強く、太ももに向かって圧迫圧が弱くなっている。
よって、弾性ストッキングは比較的厚手の生地で製作されており、夏季において発汗し蒸れ感が生じる課題があった。
患者らは、皮膚の掻痒感により掻把行動を惹起し、皮膚創傷を生じることがある。
また、蒸れ感から不快感を生じ患者の治療モチベーション低下や装着中断といった問題が生じることもある。
これらの行動は浮腫増加や蜂窩織炎発症要因となるリスクを有しており、患者らが安心してリンパ浮腫管理を継続できる環境整備が求められている。
Elastic stockings are used to improve the return of lower limb venous flow.
Moreover, elastic stockings for medical use are used as one of the compression therapies for lymphedema.
In order to facilitate the flow of venous blood and lymph in the direction of the heart, this elastic stocking has the strongest pressure at the ankle and the pressure at the thigh is weaker.
Therefore, the elastic stockings are made of a relatively thick fabric, and there is a problem in which sweating occurs and a feeling of stuffiness occurs in the summer.
Patients may provoke scratching behavior due to itching of the skin, resulting in skin wounds.
In addition, the feeling of stuffiness may cause discomfort and cause problems such as reduced patient motivation and interruption of wearing.
These behaviors have the risk of increasing edema and causing cellulitis, and there is a need for an environment that allows patients to continue to manage lymphedema with peace of mind.
特許文献１には蒸れ感を軽減する目的で、ポリアミド繊維と弾性繊維からなるストッキングにおいて少なくともレッグ部に吸湿差率ΔＭＲが２．５％以上である生地が使用されている血流速促進弾性ストッキングを開示する。
しかし、この弾性ストッキングは接触冷感を有するものではない。
Patent Document 1 discloses a blood flow velocity promoting elastic stocking in which a fabric having a moisture absorption difference ΔMR of 2.5% or more is used at least in a leg part of a stocking made of polyamide fiber and elastic fiber for the purpose of reducing the feeling of stuffiness. Is disclosed.
However, this elastic stocking does not have a cold feeling of contact.
本発明は、夏季において接触冷感に優れ、且つ薄さ及び紡糸安定性に優れた弾性ストッキングの提供を目的とする。 An object of the present invention is to provide an elastic stocking that is excellent in cool contact feeling in summer and excellent in thinness and spinning stability.
本発明に係る弾性ストッキングは、キュプラとポリエステルとの混撚糸を用いたものであることを特徴とする。 The elastic stocking according to the present invention is characterized by using a mixed twisted yarn of cupra and polyester.
キュプラは、綿花を採取した後の綿実の表面に密生している２〜６ｍｍのコットンリンターと称される繊維を原料としたものである。
シルクに似た光沢があり、しなやかで肌触りが良く吸湿性がある。
キュプラはセルロース系繊維であり、このセルロース系繊維としては木材パルプを原料としたレーヨンがある。
これらセルロース系繊維は、肌に接触したときの接触冷感が生じる。
本発明では、レーヨンよりも繊維の細いキュプラを用いた。
しかし、キュプラだけでは弾性ストッキングに要求される圧迫圧が充分に得られないので、本発明は弾性糸にすべく紡績する際に、キュプラとポリエステルとの糸を撚り合せたものである。
ポリエステルはエステル縮合された合成繊維であり、高強度であるとともに後述するように糖アルコールを付加しやすい。
本発明において、キュプラとポリエステルの割合はキュプラの配合比率として２０〜４０％の範囲が好ましい。
また、キュプラ，ポリエステルに例えば、ポリウレタン等の他の弾性糸を撚り合せてもよい。
Cupra is made from fibers called cotton linters of 2 to 6 mm that are densely grown on the surface of cotton seeds after collecting cotton.
It has a luster similar to silk, is supple, soft and hygroscopic.
Cupra is a cellulosic fiber, and the cellulosic fiber includes rayon made from wood pulp.
These cellulosic fibers produce a feeling of cool contact when in contact with the skin.
In the present invention, a cupra having finer fibers than rayon is used.
However, since the compression pressure required for the elastic stockings cannot be obtained sufficiently only with cupra, the present invention is obtained by twisting cupra and polyester yarns when spinning to make an elastic yarn.
Polyester is an ester-condensed synthetic fiber that has high strength and is easy to add sugar alcohol as described later.
In the present invention, the ratio of cupra to polyester is preferably in the range of 20 to 40% as the blending ratio of cupra.
Moreover, you may twist other elastic yarns, such as a polyurethane, to a cupra and polyester, for example.
本発明において、前記混撚糸は天然物由来の糖アルコールによる涼感加工が施されているのが好ましい。
糖アルコールにて涼感加工を行うと、キュプラによる接触冷感に持続性を付与することができる。
糖アルコールとしては、キシリトール，ソルビトール，グリセロール，エリスリトール，マルチトール，マンニトール等が例として挙げられる。
本発明においては、天然物から抽出したキシリトールが好ましい。
涼感加工としては繊維への練り込み、吸着、あるいはマイクロカプセル吸着等、各種方法が採用される。
In the present invention, the mixed twisted yarn is preferably subjected to a cool feeling processing with a sugar alcohol derived from a natural product.
When a cool sensation process is performed with sugar alcohol, sustainability can be imparted to the cold feeling of contact by cupra.
Examples of sugar alcohols include xylitol, sorbitol, glycerol, erythritol, maltitol, mannitol and the like.
In the present invention, xylitol extracted from natural products is preferred.
As the cool feeling processing, various methods such as kneading into fibers, adsorption, or microcapsule adsorption are employed.
本発明に係る弾性ストッキングは、前記混撚糸を用いて筒状に丸編みで構成されていてよく、丸編みはメッシュ編みで構成されていてよい。
弾性ストッキングとしては、足首の圧迫圧が１０〜４０ｍｍＨｇ、好ましくは２０〜４０ｍｍＨｇがよい。
The elastic stocking according to the present invention may be configured by circular knitting in a cylindrical shape using the mixed yarn, and the circular knitting may be configured by mesh knitting.
As an elastic stocking, the pressure of an ankle is 10 to 40 mmHg, preferably 20 to 40 mmHg.
本発明に係る弾性ストッキングは、キュプラとポリエステルを組み合せることで、さらには糖アルコールによる涼感加工を行うことで、これまで市販されている医療用の弾性ストッキングと同等の圧迫圧を確保しつつ、涼感性に優れた弾性ストッキングが得られる。
また、本発明に係る弾性ストッキングは冷凍庫に保管した後に使用するとさらに効果的である。
The elastic stocking according to the present invention is a combination of cupra and polyester, and further by performing a cool feeling processing with sugar alcohol, while ensuring a compression pressure equivalent to a medical elastic stocking that has been marketed so far, An elastic stocking with excellent coolness can be obtained.
The elastic stocking according to the present invention is more effective when used after being stored in a freezer.
