A method for adhering the fibers of a nonwoven fabric to each other by mixing with the fibers constituting the nonwoven fabric. The present invention relates to hot-melt polyester flat conjugate fibers suitable for obtaining flexible nonwoven fabrics.

点がある。(Problems to be solved by the invention) In order to obtain a nonwoven fabric with good flexibility, single-component type fosotomel [fiber is preferable, but since this fiber has extremely low strength, it is mixed with a card or other opening machine. When opening, these fibers are cut and fall off in powder form. There are drawbacks such as variations in the I'i cotton ratio and scattering of fluff.

を有する不織布が得られないという問題がある。On the other hand, core-sheath type hot melt fibers do not have such drawbacks, but when they are heat-bonded, the core-sheath type hot melt fibers remain in a fixed form between the base fibers, increasing their rigidity and creating a flexible nonwoven fabric. The problem is that you can't get it.

本発明者らは、上記の問題を解決すべく鋭意検討の結果

題が解決されることを兇出し１本発明に到達した。(Means for Solving the Problem) As a result of intensive studies to solve the above problem, the present inventors flattened the cross section of the fiber, arranged a hot melt component with a low softening point at the tip, and The present invention was based on the discovery that the above-mentioned problems can be solved by creating a bosotomel type composite fiber by disposing a component with a high softening point in the fiber.
すなわち１本発明の要旨は次のとおりである。That is, the gist of the present invention is as follows.

度以］二はポリエステル■３が占めるようにすることが
好ましい。In the present invention, polyester A is placed at the tip of the flat cross-section fiber, but since polyester A has a lower melt viscosity than polyester B during melt spinning, it is bonded to cover the tip of polyester B. However, it is desirable to place the polyester A at the tip as much as possible. When the area where polyester 8 covers polyester B increases, polyester A completely covers polyester 13 before adhering to the base fiber during heat bonding, and the hot melt fiber becomes rigid, reducing the flexibility of the nonwoven fabric. Since Jiff movement occurs, it is preferable that about 30% or more of the fiber surface be occupied by polyester (3).

ース繊維の捲縮形態をといった問題が生ずる。Polyester A needs to have a softening point of 90 to 160°C. If the softening point of polyester A is less than 90°C, the melt viscosity during spinning will be too low and it will be difficult to place it at the tip, resulting in a decrease in adhesive strength.
If the temperature exceeds .degree. C., the heating bonding temperature must be increased, which causes problems such as the crimp form of the base fibers.

のとすることが必要である。Polyester B is preferably one with a softening point as high as possible within the range that can form a good composite fiber together with polyester 8, in order not to deteriorate the physical properties of the nonwoven fabric that is mixed and heat-bonded. It is necessary to have the following.

ポリエステルＡとＢとの軟化点の差が大きいときは。In addition, the composite ratio of polyesters A and B cannot be determined unconditionally depending on the shape of the spinning nozzle, spinning conditions, etc.
It is desirable that A/B = 0.2 to 2 in terms of weight. If this ratio is less than 0.2, it will be difficult to maintain a predetermined cross-sectional shape and the adhesive strength will be reduced. On the other hand, if it exceeds 2, polyester A will form a core-sheath type composite fiber coated with polyester B. It's so close that it's inappropriate. In addition,
When the difference in softening point between polyesters A and B is large.
ポリエステルＡがＢを被覆する形になりやすいので、こ
の比率を比較的低くするのがよい。Since polyester A tends to cover polyester B, it is better to keep this ratio relatively low.

ある。(Function) The fiber of the present invention is a flat cross-section fiber in which a hot melt component with a low softening point is arranged at the tip and a component with a high softening point is arranged in the center, so it can be mixed into a nonwoven fabric and heat-treated. Since the hot melt component remaining in the form of fibers is flat, it is easily deformed in the long axis direction of the cross section, and the hese fibers can be effectively bonded without impairing the flexibility of the nonwoven fabric.
