好適な熱融着性複合繊維を得たものである。The present invention is characterized in that the high melting point component constituting the conjugate fiber contains an inorganic filler having a plate-like particle shape in an amount of 0.1 to 13% based on the weight of the high melting point component, whereby bulkiness and high melting point are obtained.

ない。Here, the term “plate-like particle shape” means not only a geometric plate-like particle shape but also all broad and flat plate-like particle shapes. Therefore, if it is flat, it may be rounded as a whole, or the edge may be rounded. Examples of the inorganic filler having such a plate-like particle shape include talc, mica (mica), alumina powder, clay, and sericite, but are not limited thereto.
板状粒子形状を有する無機系フィラーを高融点成分に
含有させた熱融着性複合繊維を使用すると、嵩高で融着
強度に優れた不織布が得られる理由は、以下の通りであ
る。The reason for using a heat-fusible conjugate fiber containing an inorganic filler having a plate-like particle shape in a high melting point component to obtain a bulky nonwoven fabric having excellent fusion strength is as follows.

性を向上させ、熱による収縮やヘタリを防止し、これに
より熱風融着加工時の繊維の融着交点の動きが抑えられ
るので、融着強度も大きくなる。That is, in the production of the heat-fusible conjugate fiber, when an inorganic filler having a plate-like particle shape is added to the high melting point component, the plate-like particles of the inorganic filler are oriented parallel to the fiber direction by spinning and drawing. Has been confirmed by microscopic observation. The orientation of the inorganic filler in this manner keeps the heat-fusible conjugate fibers high in rigidity. Therefore, in the production of a nonwoven fabric by hot-air fusion of a web of heat-fusible conjugate fibers, And a bulky nonwoven fabric can be obtained without losing pressure. In addition, the inorganic filler added to the high melting point component improves the heat resistance of the heat-fusible conjugate fiber, prevents shrinkage and settling due to heat, and thus moves the fusion intersection of the fiber during hot-air fusion processing. , The fusion strength is also increased.

機系フィラーを使用したことにより、嵩高で融着強度の
強い不織布が得られる理由は上述の通りであるが、この
無機系フィラーの量が高融点成分の重量に対して0.1％
未満であると、不織布は融着強度は満足するが嵩高にな

強度は小さくなる。これに対し、0.1〜13％の範囲であ
ると嵩高で高融着強度を有する不織布が得られる。従っ
て無機系フィターの量は0.1〜13％に限定される。In the heat-fusible conjugate fiber, by using the inorganic filler having a plate-like particle shape, the reason why a nonwoven fabric having a high fusible strength with a large bulk is obtained is as described above. 0.1% by weight of high melting point component
If it is less than 1, the nonwoven fabric will satisfy the fusion strength but will not be bulky. If it exceeds 13%, the nonwoven fabric will be bulky, but the fusion strength will be small. On the other hand, when the content is in the range of 0.1 to 13%, a nonwoven fabric having bulkiness and high fusion strength can be obtained. Therefore, the amount of the inorganic filter is limited to 0.1 to 13%.
なお、板状粒子形状を有する無機系フィラーの粒径は
150メッシュ全通（110μ以下）であるのが好ましい。そ
の理由は、150メッシュで残渣のある無機系フィラーを
用いると、紡糸性が悪化し、またフィルターづまりによ

る。無機系フィラーの特に好ましい粒径は200メッシュ
全通（75μ以下）である。The particle size of the inorganic filler having a plate-like particle shape is
It is preferably 150 mesh (110 μ or less). The reason is that when an inorganic filler having a residue of 150 mesh is used, spinnability deteriorates, and productivity is remarkably lowered due to an increase in discharge pressure due to filter clogging. A particularly preferred particle size of the inorganic filler is 200 mesh (75 μ or less).

ある。From FIGS. 1 and 2, in the nonwoven fabrics obtained from the composite fibers of Comparative Examples 2 to 6, the respective plots are almost positioned on a straight line having a negative gradient, and the breaking length increases with the increase in the specific volume. It is apparent that it is difficult to decrease, that is, to simultaneously satisfy both bulkiness and high fusion strength.

D, MD), the fusion strength of the nonwoven fabric of Comparative Example 5 is much lower than the fusion strength of the nonwoven fabrics of Examples 2, 4, and 5, and as a result, the nonwoven fabric obtained from the composite fiber of the present invention. The advantage of is obvious.
比較例７〜８ タルクの代りに、本発明で用いられる板状粒子形状を

不織布を得た。Comparative Examples 7 to 8 Instead of talc, calcium carbonate (2480K manufactured by Takehara Chemical Co., Ltd.) and titanium oxide, which are not included in the inorganic filler having a plate-like particle shape used in the present invention, were added to the weight of the high melting point component. Examples 1 to 6 except that 2% was used for each.
After obtaining the sheath-core type composite fibers of Comparative Examples 7 and 8 in the same manner as in Example 1, nonwoven fabrics were obtained from these composite fibers in the same manner as in Examples 1 to 6.
比較例７及び８の複合繊維から得られた不織布の比容
積及び裂断長（TD,MD）の値を表−１に、そして比容積
と裂断長との関係を第１図及び第２図に示す。Table 1 shows the values of the specific volume and the breaking length (TD, MD) of the nonwoven fabric obtained from the composite fibers of Comparative Examples 7 and 8, and FIGS. 1 and 2 show the relationship between the specific volume and the breaking length.

融点成分中にあってマイナスの作用をするからと考えら
れる。As is clear from FIGS. 1 and 2, even if calcium carbonate or titanium oxide is used, bulkiness and high fusion strength cannot be simultaneously satisfied, and on the contrary, it is inferior to the case where no additive is added. Results were also obtained. This is because calcium carbonate and titanium oxide used as additives have a spherical particle shape instead of a plate-like particle shape, so that they do not contribute to simultaneous achievement of bulkiness and high fusion strength, This is considered to be due to a negative effect in the high melting point component in some cases.
