【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、繊維を熱融着し、もしくは熱可塑性樹脂を
介して接着し、或いは合成樹脂接着剤で接着して形成し

るための不織布の柔軟処理方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a flexible non-woven fabric formed by heat-sealing fibers, adhering them through a thermoplastic resin, or adhering with a synthetic resin adhesive. The present invention relates to a method of softening a non-woven fabric for imparting texture and improving texture, touch and the like.
不織布は、織布工程を経ないで、繊維を不定方向或いは
一定方向に配列させ、熱融着、熱可塑性樹脂を介在させ
ての接着、合成樹脂接着剤による接着などによって、相
互に構成繊維を接合することにより製造されている。A non-woven fabric is formed by arranging fibers in an indeterminate direction or a fixed direction without going through a woven process, and heat-sealing, bonding with a thermoplastic resin interposed, bonding with a synthetic resin adhesive, etc. It is manufactured by joining.
このため、不織布は、熱融着によって構成繊維相互を接

残ることになって、柔軟性に欠けるといった欠点があ
る。For this reason, when a non-woven fabric is formed by joining constituent fibers to each other by thermal fusion, the hardness at the fused contact portion will remain to some extent, and the non-woven fabric will be made of thermoplastic resin or synthetic resin adhesive. In the case where the fibers are adhered to each other, the produced nonwoven fabric retains the properties of the resin itself as they are, and thus has a drawback of lacking flexibility.
このような不織布に存在する硬さを消失させる改善方法
としては、従来、その不織布に対しカレンダー加工によ
る圧延処理を施すことが行なわれている程度である。As a method for improving the hardness existing in such a non-woven fabric, conventionally, the non-woven fabric is subjected to a rolling treatment by calendering.
しかしながら、カレンダー加工処理は、対向するローラ
間に不織布を通して高い圧力で不織布を挾圧するため、
その処理後の不織布には扁平感が生まれ、実際に厚みが
減少し、また表面に好ましくない光沢（テカリ）が発生
する等といった問題点がある。However, in the calendering process, since the nonwoven fabric is sandwiched between the rollers facing each other with high pressure,
The non-woven fabric after the treatment has a problem that a flatness is produced, the thickness is actually reduced, and unfavorable gloss (shiny) is generated on the surface.
そして、従来は、カレンダー加工処理の他に、不織布の
持つ硬さを改善するための有効な方法は無かった。And, conventionally, there has been no effective method for improving the hardness of the nonwoven fabric other than the calendering treatment.
そこで、この発明は、不織布に柔軟性を付与することが

れている。The nonwoven fabric softening method according to the present invention is a continuous steaming chamber filled with saturated steam or heating steam, or in a heating chamber in which atmospheric air is heated, the nonwoven fabric in the form of a long strip is continuously tensioned. By changing the contact position and contact area between the constituent fibers that make up the non-woven fabric by applying micro-vibration to the non-woven fabric over the entire width direction of the non-woven fabric while moving by the ultrasonic vibration device or high-frequency vibration device. It is characterized by making it.

した不織布が得られる。In the soft treatment method of the non-woven fabric according to the present invention, when the non-woven fabric is carried into a steaming chamber filled with saturated steam or heated steam, or when the atmospheric air is heated, the non-woven fabric is heated to a crystal structure of its constituent fibers. Change will occur.
The degree of this change depends on the type of fiber, and generally, the higher the content of olefin chains in the molecule, the more the fiber tends to soften. In any case, the constituent fibers of the nonwoven fabric are somewhat softened by heat. On the other hand, in many cases, the fused portions and adhesives that bond the constituent fibers together also tend to soften due to heat. In this manner, when the constituent fibers themselves, the adhesive, etc. are softened, and the tension in the traveling direction is applied to the nonwoven fabric as the nonwoven fabric is transferred, the contact positions between the constituent fibers move, and further The contact area changes as the fiber moves. Then, in the softened state of the constituent fibers, the adhesive, etc., when a slight vibration is applied to the nonwoven fabric in the tensioned state by the ultrasonic vibration device or the high frequency vibration device over the entire width direction of the nonwoven fabric, the constituent fibers The movement of the contact position and the change of the contact area between them are further promoted. When the non-woven fabric in which the contact position and the contact area between the constituent fibers are changed in this manner is carried out from the steam room or the like and cooled, a non-woven fabric having improved flexibility as compared with the non-treated non-woven fabric can be obtained.

られる。In this apparatus, vibration applying mechanisms B 1 , B 2 , ..., B 8 for applying vibration to the nonwoven fabric W between the tensioned guide rolls are installed. These vibration imparting mechanisms B 1 to B 8 are constituted by an ultrasonic vibration device or a high frequency vibration device. Fig. 2 shows a vibration imparting device of the oscillating rotation type, and Fig. 3 shows a vibration imparting device of the ultrasonic vibrating type. In each case, the vibrator makes line contact with the entire area of the nonwoven fabric W in the horizontal direction. The non-woven fabric W is brought into direct contact with the non-woven fabric W to give a slight vibration. That is,
FIG. 2 is a perspective view showing an oscillating rotation type vibration imparting apparatus. This apparatus uses a rotary drive motor 24 to rotate a rotary rod 20 having long grooves 22 on both side surfaces, for example, 7,000 times per minute. By rotationally driving the above, the structure is such that vibration is simultaneously given to the downward traveling non-woven fabric W and the upward traveling non-woven fabric W which are in contact with the both side surfaces. Further, FIG. 3 shows an ultrasonic vibration generator.
FIG. 11 is a perspective view showing a vibration applying device including a vibrator and a vibrator, and the vibrator is in contact with the nonwoven fabric W in a straight line in a horizontal direction, and applies a slight vibration to the nonwoven fabric W. And
Since these vibrations are applied while tension is applied to the nonwoven fabric W, the nonwoven fabric W is surely vibrated slightly.

The heat raises its temperature to near 100 ° C. Then, the non-woven fabric W passes through the guide rolls G 1 and G 2 and is then heated by the guide roll groups R 1 to R 10 and L 1 to L 11 in the heating chamber.
While being transferred in the tensioned state in the inside 10, slight vibrations are applied by the vibration applying mechanisms B 1 to B 8 . By this heating, tension, and vibration, the non-woven fabric W is rubbed and unraveled, and the contact position between the constituent fibers moves and the contact area changes, and the non-woven fabric W passes through the guide rolls G 3 and G 4 in the steam chamber. When it is carried out of the container 10, squeezed with a squeeze roll 18, and cooled, a nonwoven fabric having improved flexibility as compared with the untreated nonwoven fabric is obtained.
