料の鞘芯型複合繊維に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to nonwoven fabrics used in needle punch carpets and the like, and fibers as raw materials thereof, and more specifically to nonwoven fabrics and fibers with excellent shape retention, light resistance, and abrasion fastness. The present invention relates to sheath-core composite fibers as raw materials.

らに車の床面形状に合わせて加熱加圧成形したカーペッ
トが主に用いられてきた。Conventionally, in the field of automotive carpets, polypropylene raw material colored fibers, which are lightweight and economical, are made into a non-woven fabric using a needle-punching method, etc., then lined with polyethylene sheets, etc., and then heated and pressure-molded to match the shape of the car's floor surface. Carpets have been mainly used.
ポリエステルを芯成分としポリエチレンを鞘成分とする
鞘芯型複合繊維は公知であシ、このような繊維を熱処理
しポリエチレンのみを融解させることにより繊維の接点
を接着させた不織布も良く知られている。Sheath-core type composite fibers having polyester as a core component and polyethylene as a sheath component are well known, and nonwoven fabrics made by heat-treating such fibers to melt only the polyethylene and bonding the contact points of the fibers are also well known. .

であるといった欠点が生じる。Carpets made of polypropylene fibers have disadvantages in that they tend to erode from the mold even after being molded under heat and pressure, and wrinkles tend to occur at the edges of the molded product. Although these drawbacks can be improved to some extent by using polyester fibers, they have the drawbacks of having a higher specific gravity and being more expensive than polypropylene fibers.

織布及びその原料繊維を提供することを目的とする。An object of the present invention is to eliminate the above-mentioned drawbacks of polyester fibers and polypropylene fibers, and to provide a nonwoven fabric that is lightweight, has good shape retention, and is inexpensive, and its raw material fibers.

れることを知シ、本発明を完成するに至った。As a result of intensive research in order to solve the above problems, the present inventors used a sheath-core type conjugate fiber containing polyester as a sheath component and polyolefin as a core component, and created a nonwoven fabric containing 30 weight percent or more of this conjugate fiber. The present invention was completed based on the knowledge that the intended purpose could be achieved by the following methods.

リエチレンテレフタレートあるいはポリ（エチレンテレ
フタレート／イソフタレート）が好ましく用いられる。The polyester used in the present invention is a polyester synthesized from dicarboxylic acids such as terephthalic acid, isophthalic acid, naphthalene-2,6-dicarboxylic acid, adipic acid, and sebacic acid, and diols such as ethylene glycol, diethylene glycol, and neopentyl glycol. It is. Among them, the melting point is 200-260°C and the intrinsic viscosity is 0.55-0.
88 (phenol/tetrafluorethane, 30°C) or poly(ethylene terephthalate/isophthalate) is preferably used.

にも特別の制限はなく、１〜１００デニールの範囲、な
かでも自動車用カーペットには６〜６０デニールのもの
が好適である。The polyester and polyolefin are composite-spun into a sheath-core type in which the polyester is a sheath component and the polyolefin is a core component. The ratio of the circumferential component is the volume ratio f80/20~20/
80, preferably in the range of 70/30 to 30/70. If the polyester content is less than 20%, the nonwoven fabric using this composite fiber will easily bleed from the mold, and if it exceeds 80%, the specific gravity will be large and the fabric will be expensive, both of which are undesirable. For other spinning conditions, conditions for ordinary polyester/polyolefin composite fibers can be used. There is no particular limit to the fineness, and a range of 1 to 100 deniers is preferred, with 6 to 60 deniers being particularly suitable for automobile carpets.

こともない。また、芯成分にのみ顔料を添加して着色し
たものは、鞘成分が保護層となるので、摩擦堅牢度や耐
光性の優れた原液着色繊維となる。The composite fibers obtained in this way have a low specific gravity due to the use of polyolefin for the core, are inexpensive, and are arranged in a cylindrical shape of highly rigid polyester, so the fibers themselves have high rigidity. Nonwoven fabrics using composite fibers also have good shape retention. Furthermore, when this nonwoven fabric is heated and pressure-molded at a temperature below the melting point of polyester and above the softening point of polyolefin, stress relaxation occurs in the polyolefin core component, improving shape retention and causing wrinkles at the edges. There's nothing to do. Furthermore, in the case where only the core component is colored by adding a pigment, the sheath component serves as a protective layer, resulting in solution-colored fibers with excellent abrasion fastness and light resistance.

等が例示できる。The nonwoven fabric of the present invention can be produced by using the above-mentioned conjugate fiber of the present invention, mixing it with other fibers as desired, and by a known method such as a needle punch method or a water needle method. Examples of other fibers that can be used in combination include rayon, polyamide fiber, polyester fiber, and acrylic fiber.
不織布中に含有される本発明の複合繊維の量が３０重量
係未満であると、加熱加圧成形した後の形状保持性が低
下するので好筐しくない。If the amount of the conjugate fiber of the present invention contained in the nonwoven fabric is less than 30% by weight, the shape retention after heating and pressure molding will be reduced, which is not desirable.

施例１と同様にニードルパンチして不織布を得た。これ
らの不織布の物性値を第２表に示した。Nonwoven fabric made only of composite fibers of the present invention (Examples 1 to 3)
The nonwoven fabric made of polyethylene terephthalate fiber (Comparative Example 1) has a higher bending stress and a smaller bending angle, so it has better shape retention. Composite fiber staples and rayon staples (fineness 2 denier, [4I length 51 cm) were mixed at various ratios shown in Table 2, and then needle punched in the same manner as in Example 1 to obtain a nonwoven fabric. Ta. Table 2 shows the physical properties of these nonwoven fabrics.
チレンを鞘成分とする複合繊維（比較例１）からなる不
織布は、曲げ応力が小さく折シ曲げ角度も９０”を超え
るのみならず、ポリエチレンの融着になる不織布は、形
状保持性ではポリプロピレン繊維（比較例３）からなる
不織布よりは優れているが実施例１〜３の不織布より形
状保持性が劣シ、摩擦堅牢度では実施例１〜３にはるか
に及ばない。The nonwoven fabric made of composite fibers containing tyrene as a sheath component (Comparative Example 1) not only has low bending stress and a bending angle of more than 90", but the nonwoven fabric that fuses polyethylene has a shape retention property that is superior to that of polypropylene fibers. Although it is superior to the nonwoven fabric of Comparative Example 3, its shape retention is inferior to the nonwoven fabrics of Examples 1 to 3, and its fastness to abrasion is far inferior to Examples 1 to 3.
比較例３の不織布はいずれの物性値にかいても実施例１
〜３に及ばない。The nonwoven fabric of Comparative Example 3 is better than Example 1 in any physical property value.
- Not as good as 3.
第２表に示されたデータから、本発明の複合繊維を３０
重重量板上含有する不織布（実施例４．５）は、その複
合繊維１００％から々る不織布（実施例２）に近似した
良い物性値を示すが、複合繊維含量が３０％未満の不織
布（比較例４）では形状保持性が大きく低下することが
分かる。From the data shown in Table 2, it was determined that the composite fiber of the present invention was
The nonwoven fabric contained on the heavy weight board (Example 4.5) shows good physical properties close to that of the nonwoven fabric made from 100% composite fibers (Example 2), but the nonwoven fabric containing less than 30% composite fiber ( It can be seen that in Comparative Example 4), the shape retention is greatly reduced.
以上that's all
