る。[0005] The nonwoven fabric of the present invention comprises a composite fiber A comprising two kinds of thermoplastic resin components having different melting points, and a fiber B having a higher melting point than the low melting point component of the thermoplastic component. A short-fiber nonwoven fabric integrated by melting a low-melting-point component, wherein the composite fiber A has a smaller fineness than the fiber B, and at least a part of the composite fiber A is crimped in a spiral shape. It is characterized by being.

高く、容易にスパイラル状となるからである。As the composite fiber A used for such a nonwoven fabric, there are a so-called bonded structure (side-by-side type) and a core-sheath structure. In the case of the core-sheath structure, the sheath is a low melting point component. Among them, the core-sheath structure is preferable because the problem of fiber breakage due to the needle punch hardly occurs, and among them, the one having the eccentric core-sheath structure is preferable. This is because the eccentric type has a high crimp ratio after heat treatment and easily becomes a spiral shape.

There should be. This is because the greater the number of crimps, the better the abrasion resistance and cushioning properties when used as a rug.

It is preferably present in a proportion of at least cm 2 . This is because the greater the proportion of crimped fibers, the better the abrasion resistance and cushioning properties when used as a rug. The number of the crimped fibers can be measured by observation with an electron microscope.

Can be obtained particularly effectively by increasing the heat treatment temperature (temperature for melting the low melting point component) of the conjugate fiber A to near the melting point of the high melting point component of the conjugate fiber A. Specifically, when the melting point of the low melting point component is (a) ° C. and the melting point of the high melting point component is (b) ° C., the heat treatment temperature (x)
It is preferred that the temperature satisfies the following equation. . (A) + 10 ≦ (x) <(b)

By doing so, the density of the composite fiber A having a small fineness increases on one side of the nonwoven fabric (the front side of the rug), and the composite fiber A can be strongly crimped in a state where the composite fiber A is point-bonded to the fiber B. Therefore, the surface on the front side of the nonwoven rug is substantially flat, but the opposite side has a fluffy feel.

ブレンドまたは共重合して得た繊維も含まれる。In the present invention, in particular, the fibers constituting the nonwoven fabric, that is, the composite fibers A and B are both made of polylactic acid-based fibers, so that the biodegradable nonwoven fabric can be processed without waste. Thus, it is possible to obtain products that can be widely used for rugs. Here, the polylactic acid-based fiber includes not only a polylactic acid fiber composed solely of a lactic acid monomer, but also a fiber obtained by blending or copolymerizing other components as long as biodegradability is not impaired.

に適した製品となることを可能とした。[0013] Conventionally, polylactic acid-based fibers are brittle and tend to break fibers, have low crimp elasticity, are hardly bulky, and have poor cushioning properties, compared to, for example, polyethylene terephthalate-based fibers. However, in the present invention, for example, a composite fiber A having a core-sheath structure composed of a polylactic acid-based component in both the core and the sheath, and a polylactic acid-based fiber B having a melting point substantially equal to that of the core component are combined. The composite fiber A has an eccentric core-sheath structure in which the composite fiber A is close to side-by-side, and the heat treatment temperature in the production of the nonwoven fabric is set close to the melting point of the core component of the composite fiber A (with the melting point of the core component). By increasing the difference (until the difference is about 5 to 15 ° C., particularly about 7 to 13 ° C.), the composite fiber A can be strongly crimped in a state where the composite fiber A is adhered to the fiber B,
As a result, it has become possible to provide a practically suitable product for a rug having abrasion resistance and cushioning properties even though it is a nonwoven fabric made entirely of polylactic acid-based fibers.

It is preferably about 0.
