Moreover, the wiping property, hand feeling (texture) and touch were also good.
- Comparative Example 1 when the content of the cellulosic fiber exceeds 80% by mass, the touch is good, but the bulkiness of the nonwoven fabric is impaired. Since the system fiber retains the chemical solution in the fiber, the remaining rate is high, which causes a poor release of the chemical solution.

- Comparative Examples 3 to 7 when other irregular cross-section polyester fibers that are not flat are used, the liquid retention is increased, but the residual ratio is extremely low. Retention is weak and causes liquid flow when using nonwoven fabric. Moreover, since it is not flat, the texture is hard and the touch is remarkably deteriorated.

Abstract
Description
・扁平度(A/B)=2.0~3.0 ・・・ (1)
・異形度(C/D)=1.0~5.0 ・・・ (2)
本発明の不織布の好ましい態様によれば、前記の多葉扁平断面ポリエステル系繊維の横断面の最大長さAを対称軸とし、対向する両凸部頂点間線分のうち、横断面最大幅Bを除いて最長となる長さをEとするとき、下記式(3)で定義される凸部比を満足することである。
・凸部比(E/B)=0.6~0.9 ・・・ (3)
本発明の不織布の好ましい態様によれば、前記の扁平多葉断面ポリエステル系繊維の単繊維繊度は2.0dtex以下である。 That is, the nonwoven fabric of the present invention is a nonwoven fabric obtained by blending 20 to 80% by mass of flat multi-leaf cross-sectional polyester fiber and 20 to 80% by mass of cellulose-based fiber, and has a cross-sectional shape of the flat multi-leaf cross-sectional polyester fiber. Is a flat shape having 6 or more protrusions, and the flat multi-leaf cross-section polyester fiber connects the maximum length of the cross-section A, the maximum width B, and the vertices of adjacent protrusions in the maximum unevenness portion. When the length of the line is C, and the length of the perpendicular drawn from the line connecting the vertices of the convex portion to the bottom of the concave portion is D, the flatness of the following formula (1) and the following formula (2) A nonwoven fabric characterized by satisfying the degree of profile at the same time.
Flatness (A / B) = 2.0 to 3.0 (1)
・ Deformation degree (C / D) = 1.0 to 5.0 (2)
According to a preferred aspect of the nonwoven fabric of the present invention, the maximum length A of the cross section of the multi-leaf flat cross-sectional polyester fiber is set as the axis of symmetry, and the cross section maximum width B among the line segments between the opposite convex vertices. When the longest length excluding is E, the convex portion ratio defined by the following formula (3) is satisfied.
・ Convex ratio (E / B) = 0.6 to 0.9 (3)
According to the preferable aspect of the nonwoven fabric of this invention, the single fiber fineness of the said flat multi-leaf cross-section polyester fiber is 2.0 dtex or less.
・扁平度(A/B)=2.0~3.0 ・・・ (1)
・異形度(C/D)=1.0~5.0 ・・・ (2)
ここで、上記Aは、上記の扁平多葉形の横断面の最長の線分の長さである。上記Bは、線分の長さAに垂直に交わる凸部の頂点間を結ぶ最大幅の線分の長さをいう。上記Cは、上記の扁平多葉形のなす最も大きな凹凸で、隣り合う凸部の頂点間を結ぶ線分の長さをいう。そして、上記Dは、上記の凸部間を結ぶ線から凹部の底点に下ろした垂線の長さをいう。 The flat multilobal cross-sectional polyester fiber used in the present invention has a flat multilobal cross-sectional shape in a single fiber cross section that satisfies the flatness of the following formula (1) and the deformity of the following formula (2) at the same time. It consists of fibers.
Flatness (A / B) = 2.0 to 3.0 (1)
・ Deformation degree (C / D) = 1.0 to 5.0 (2)
Here, A is the length of the longest line segment of the cross section of the flat multilobal shape. Said B says the length of the largest line segment which connects between the vertexes of the convex part which intersects perpendicularly with the length A of the line segment. Said C is the largest unevenness which said flat multilobal form makes, and says the length of the line segment which connects between the vertexes of an adjacent convex part. And said D says the length of the perpendicular drawn from the line which connects between said convex parts to the bottom point of a recessed part.
・凸部比(E/B)=0.6~0.9 ・・・ (3)
凸部比(E/B)は、最大幅BおよびE、最大長さAの各凸部頂点を結ぶ線を描いた際に得られる略楕円形状の歪度合いを測る指標としての意味を持つ。凸部比があまりに小さい場合、凹部深さが減少するとともに、その横断面形状は限りなく扁平十字形に近似した形状となる。そのため、繊維間の空壁率が低下し、吸保水性が低下する。また、肌に触れた際、扁平十字形状に近しくなるために接触する凸部数が減少し、肌触り感とソフト性も低下する。従って、凸部比は0.6以上であることが好ましい。 The flat multilobal cross-section polyester fiber used in the present invention has the maximum length A of the cross section as the axis of symmetry, and is the longest length excluding the maximum cross section width B among the opposing line segments between the vertices. When the thickness is E, it is made of polyester fiber satisfying the convex portion ratio defined by the following formula (3).
・ Convex ratio (E / B) = 0.6 to 0.9 (3)
The convex portion ratio (E / B) has a meaning as an index for measuring the degree of distortion of a substantially elliptical shape obtained when a line connecting the convex vertices having the maximum widths B and E and the maximum length A is drawn. When the convex portion ratio is too small, the depth of the concave portion is reduced, and the cross-sectional shape thereof is infinitely approximate to a flat cross shape. Therefore, the void ratio between the fibers decreases, and the water absorption and retention capacity decreases. Moreover, when it touches skin, since it becomes close to a flat cross shape, the number of convex parts which contact is reduced, and a touch feeling and softness also fall. Therefore, the convex portion ratio is preferably 0.6 or more.
するため、本発明の目的とする対人向け清拭用や美容用の不織布として最適である。 The non-woven fabric produced and produced in this way has excellent water absorption and softness and is suitable as a non-woven fabric for personal wiping and beauty purposes.
