Description

【０００１】
【発明の属する技術分野】
この発明は、通気性のよい使い捨て着用物品に関する。
【０００２】
【従来の技術】
従来、不織布製の使い捨て着用物品の通気性を向上させる手段として着用物品の所要部位にメッシュ生地を使用したり、不織布に通気孔を設けたりすることはよく知られている。
【０００３】
【発明が解決しようとする課題】
前記従来技術のうち、所要部位にメッシュ生地を使用する場合には、不織布の他にメッシュ生地を用意しなければならないという材料調達の繁雑さに加え、不織布の裁断が複雑になるとか、不織布とメッシュ生地とを接合する時間を要するとかという煩わしさがある。また、不織布に通気孔を設けるときには、それに使用する機械装置にもよるが、比較的小さい通気孔を互いに接近させることが難しい。例えば、不織布の繊維間隙よりも僅かに大きい程度の通気孔を繊維径程度に互いに接近させて形成することが難しい。
【０００４】
そこで、この発明が課題とするのは、不織布製の着用物品において、メッシュ生地のような別部材を使用することなく、所要部位に多数の微細な通気孔を形成することにある。
【０００５】
【課題を解決するための手段】
前記課題解決のために、この発明が対象とするのは、不織布によって身体を被覆する使い捨ての着用物品であり、この発明が特徴とするところは、前記不織布において、所要部位が延伸されて複数条のひだを形成するとともに、前記ひだの部分において前記不織布を構成する繊維の間隙が前記所要部位周辺における繊維の間隙よりも拡大していること、にある。
【０００６】
かかる発明には、次の実施態様がある。
（１）前記不織布が使い捨てのガウン、シャツ、ズボン、パンツ、帽子いずれかのものである。
（２）前記所要部位が使い捨てガウンの前身頃、後身頃、袖、およびマスクのいずれかに位置している。
【０００７】
【発明の実施の形態】
添付の図面を参照し、この発明に係る使い捨て着用物品の詳細を説明すると、以下のとおりである。
【０００８】
図１，２は、使い捨て着用物品の一例である使い捨ての手術用ガウン１の正面図と背面図である。ガウン１は、前身頃２と、後身頃３と、一対の袖４と、マスク６とを有する。後身頃３は不織布製のもので、開閉できるように第１，２不織布３Ａと３Ｂとに二分され、これら両不織布３Ａ，３Ｂが止着用テープ７を使用して閉じられている。マスク６は、口許に対する被覆部８と、頭部に掛回する伸縮性の掛けひも９とを有する。前身頃２は、２枚の不織布１１，１２を中央の線１３で縫合または溶着することにより形成されている。後身頃３の第１不織布３Ａは、胴周り側部の線１４で前身頃２の不織布１２に取り付けられ、後身頃３の第２不織布３Ｂは胴周り側部の線１５で前身頃２の不織布１１に取り付けられている。袖４は、前身頃２と後身頃３とに対して取り付けられている。
【０００９】
図２に示されるように、第１，２不織布３Ａ，３Ｂが着用者の背中に当接する部位１６，１７と、マスク６の被覆部８の中央部位２０とには、多数のギャザー２１，２２，２３が形成されている。
【００１０】
図３は、図２で仮想線によって囲まれた第２不織布３Ｂの部分ＩＩＩの拡大図である。部分ＩＩＩは、ギャザー２２のある部位１７と、部位１７の近傍でギャザー２２のない部位１８とを含んでいる。部位１７では、第２不織布３Ｂが室温または加熱下でプレス加工されて変形し、起伏を繰り返すギャザー２２を形成している。部位１８はプレス加工されておらず、第２不織布３Ｂが平坦な状態にある。
【００１１】
図４は、図３に示された第２不織布３Ｂの部分ＩＩＩの端面を拡大した図面である。部位１７では不織布がプレス加工を施されて伸長することに伴い、第２不織布３Ｂの構成繊維２６が互いに離間し、繊維間隙が比較的大きくなっている。プレス加工されていない部位１８では、繊維２６が互いに密着しており、繊維間隙が部位１７のそれよりも小さい。それゆえ、第２不織布３Ｂでは、部位１７における通気性が部位１８のそれよりも高くなる。また、多数のギャザー２２からなる部位１７は、部位１７を平面的に見たときよりも実際の表面積が大きく、そうしたことによっても部位１７は通気性が高くなる。後身頃３の第１不織布３Ａは、第２不織布３Ｂと同様に形成されており、部位１６はその周辺よりも高い通気性を有する。
【００１２】
一例として、第２不織布３Ｂが坪量１６ｇ／ｍ２ のポリプロピレンのメルトブローン不織布の上下に坪量１６ｇ／ｍ２ のポリプロピレンのスパンボンド不織布を重ねて間欠的に溶着することによって得たものである場合、部位１８におけるＪＩＳ Ｌ １０９６による通気度は２０〜７０ｃｃ／ｃｍ２ ／ｓｅｃであり、これに２．５ｍｍ幅で深さ２．５ｍｍの溝を２．５ｍｍ間隔でプレス加工してひだ２２の代わりとした部位１７の通気度は相対的に高く、５０〜１２０ｃｃ／ｃｍ２ ／ｓｅｃであった。
【００１３】
不織布は、それを製造するときの機械方向（ＭＤ方向）に向かって構成繊維が配向する傾向にあるから、この発明で形成するひだ２１や２２，２３はそれがＭＤ方向へ延びるようにして、不織布がそれと交差する方向（ＣＤ方向）へ延伸されるようにすれば、構成繊維は繊維間隙が比較的大きくなるように動く。一方、ひだ２１や２２，２３がＣＤ方向へ延びるようにして、不織布がＭＤ方向へ延伸されるようにすれば繊維間隙はあまり大きくならない。繊維間隙は、不織布の延伸度合によって大きく左右されるが、この発明に係る着用物品では、構成繊維の配向方向に対してひだ２１〜２３の延びる方向を様々に変化させることによっても繊維間隙の大きさを調整することができる。
【００１４】
マスク６における中央部位２０は、部位１７と同様にプレス加工によって生じた多数のギャザー２３を有し、ギャザー２３のないその周辺の部位に比べて高い通気性を有する。このマスク６は、それが着用されたときには、鼻や口許の***に対応してギャザー２３が伸長してマスク６が適度にふくらみ、顔面によくフィットする。このように、マスク６のギャザー２３は、マスク６の局所的な通気性の向上と、フィット性の向上とに寄与する。
【００１５】
ガウン１を例にして説明したこの発明は、不織布製の使い捨てのシャツ、ズボン、パンツ、帽子等によって実施することもできる。
【００１６】
【発明の効果】
この発明に係る着用物品は、物品の通気性を局部的に向上させるのにメッシュ生地のような別部材を必要としないから、物品の通気性を向上させることが容易である。通気性の向上は、物品に使用した不織布を延伸して繊維間隙を拡大することによるから、微細な通気性の間隙を局部的に密着させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a disposable wearing article having good air permeability.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, it is well known that a mesh cloth is used at a required portion of a worn article or a ventilation hole is provided in a nonwoven fabric as a means for improving the air permeability of a disposable wearing article made of a nonwoven fabric.
[0003]
[Problems to be solved by the invention]
Among the above-mentioned conventional techniques, when using a mesh fabric for a required part, in addition to the complexity of material procurement that a mesh fabric must be prepared in addition to the nonwoven fabric, the cutting of the nonwoven fabric becomes complicated, There is an annoyance that it takes time to join the mesh fabric. In addition, when vents are provided in the nonwoven fabric, it is difficult to make relatively small vents close to each other, depending on the mechanical device used for the vents. For example, it is difficult to form air holes slightly larger than the fiber gap of the nonwoven fabric so as to be close to each other with a fiber diameter.
[0004]
Therefore, an object of the present invention is to form a large number of fine ventilation holes in required portions of a nonwoven fabric wearing article without using a separate member such as a mesh fabric.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, an object of the present invention is a disposable wearing article covering a body with a nonwoven fabric, and the present invention is characterized in that a required portion of the nonwoven fabric is stretched to a plurality of articles. And the gap between the fibers constituting the nonwoven fabric at the fold is larger than the gap between the fibers around the required portion.
[0006]
This invention has the following embodiments.
(1) The nonwoven fabric is one of disposable gowns, shirts, pants, pants, and hats.
(2) The required part is located on one of a front body, a back body, a sleeve, and a mask of the disposable gown.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
The details of the disposable wearing article according to the present invention will be described below with reference to the accompanying drawings.
[0008]
1 and 2 are a front view and a rear view of a disposable surgical gown 1 which is an example of a disposable wearing article. The gown 1 has a front body 2, a back body 3, a pair of sleeves 4, and a mask 6. The back body 3 is made of a non-woven fabric, and is divided into first and second non-woven fabrics 3A and 3B so as to be opened and closed. Both non-woven fabrics 3A and 3B are closed using a fastening tape 7. The mask 6 has a covering portion 8 for the mouth and an elastic lace 9 wrapped around the head. The front body 2 is formed by sewing or welding two nonwoven fabrics 11 and 12 at a center line 13. The first nonwoven 3A of the back body 3 is attached to the nonwoven fabric 12 of the front body 2 by the line 14 of the waist side, second nonwoven fabric 3B of the back body 3 is the waist side lines 1 5 of the front body 2 It is attached to the nonwoven fabric 11. The sleeve 4 is attached to the front body 2 and the back body 3.
[0009]
As shown in FIG. 2, a large number of gathers 21 and 22 are provided at the portions 16 and 17 where the first and second nonwoven fabrics 3 </ b> A and 3 </ b> B abut on the back of the wearer and at the central portion 20 of the covering portion 8 of the mask 6. , 23 are formed.
[0010]
FIG. 3 is an enlarged view of a portion III of the second nonwoven fabric 3B surrounded by a virtual line in FIG. The part III includes a portion 17 having gathers 22 and a portion 18 having no gathers 22 near the portion 17. In the portion 17, the second nonwoven fabric 3B is deformed by press working at room temperature or under heating to form a gather 22 which repeats undulations. The portion 18 is not pressed, and the second nonwoven fabric 3B is in a flat state.
[0011]
FIG. 4 is an enlarged view of an end face of a portion III of the second nonwoven fabric 3B shown in FIG. In the portion 17, the nonwoven fabric is subjected to the press working and stretched, so that the constituent fibers 26 of the second nonwoven fabric 3B are separated from each other and the fiber gap is relatively large. In the non-pressed part 18, the fibers 26 are in close contact with each other, and the fiber gap is smaller than that in the part 17. Therefore, in the second nonwoven fabric 3B, the air permeability at the portion 17 is higher than that at the portion 18. In addition, the portion 17 including a large number of gathers 22 has a larger actual surface area than when the portion 17 is viewed in a plan view, and thus the portion 17 has high air permeability. The first nonwoven fabric 3A of the back body 3 is formed similarly to the second nonwoven fabric 3B, and the portion 16 has higher air permeability than the periphery thereof.
[0012]
As an example, if it were obtained by the second non-woven fabric 3B is intermittently welded superimposed spunbonded nonwoven polypropylene having a basis weight of 16g / m 2 and below the melt blown nonwoven fabric of polypropylene having a basis weight of 16g / m 2 The air permeability according to JIS L 1096 at the portion 18 is 20 to 70 cc / cm 2 / sec, and a groove having a width of 2.5 mm and a depth of 2.5 mm is pressed at intervals of 2.5 mm to replace the fold 22. The air permeability of the portion 17 was relatively high, and was 50 to 120 cc / cm 2 / sec.
[0013]
Since the constituent fibers of a nonwoven fabric tend to be oriented in the machine direction (MD direction) when the nonwoven fabric is manufactured, the folds 21, 22, and 23 formed in the present invention are arranged so that they extend in the MD direction. When the nonwoven fabric is stretched in a direction crossing the same (CD direction), the constituent fibers move so that the fiber gap is relatively large. On the other hand, if the folds 21, 22, and 23 are extended in the CD direction and the nonwoven fabric is stretched in the MD direction, the fiber gap is not so large. Although the fiber gap is greatly affected by the degree of stretching of the nonwoven fabric, in the wearing article according to the present invention, the size of the fiber gap is also changed by changing the extending direction of the folds 21 to 23 with respect to the orientation direction of the constituent fibers. Can be adjusted.
[0014]
The central portion 20 of the mask 6 has a large number of gathers 23 formed by press working like the portion 17 and has higher air permeability than the surrounding portion without the gathers 23. When the mask 6 is worn, the gathers 23 are extended corresponding to the bulges of the nose and mouth, so that the mask 6 swells appropriately and fits well on the face. Thus, the gathers 23 of the mask 6 contribute to the improvement of the local air permeability of the mask 6 and the improvement of the fit.
[0015]
The present invention described by taking the gown 1 as an example can also be implemented by a disposable shirt, pants, pants, hat, and the like made of nonwoven fabric.
[0016]
【The invention's effect】
Since the wearing article according to the present invention does not require a separate member such as a mesh fabric to locally improve the air permeability of the article, it is easy to improve the air permeability of the article. The improvement in air permeability is achieved by stretching the nonwoven fabric used in the article to expand the fiber gap, so that the fine air gap can be locally adhered.
