である。Detailed Description of the Invention (Field of Application for Industry 1) The present invention relates to a nonwoven fabric having a fixed nonwoven structure by point bonding a thermoplastic resin to a nonwoven fabric web, and particularly relates to a nonwoven fabric with a soft texture similar to that of knitted fabrics or woven fabrics. The present invention relates to a nonwoven fabric with excellent surface abrasion resistance, tear strength, etc., and a method for producing the same.
（従来の技術）
従来、不織布ウェブの接合方法に関しては種々のものが

融着する方法が主に知られている。(Prior Art) Conventionally, various methods for joining nonwoven fabric webs have been proposed. For example, a method in which a nonwoven fabric web is impregnated with a resin dispersion solution and then dried, and a method in which a nonwoven fabric web is partially heat-sealed are known.

は、まだ柔軟性等が解決されていない。However, the flexibility, surface abrasion resistance, and tear strength of nonwoven fabrics bonded by these methods are inferior to knitted fabrics,
It had the disadvantage that it was far from being comparable to that of textiles. Furthermore, a method is known in which a nonwoven fabric web is laminated with a low melting point resin powder (Japanese Patent Laid-Open No. 83-152472). However, although the characteristics of the nonwoven fabric webs to be joined are thought to affect the joining conditions (laminating conditions), flexibility and other issues have not yet been resolved with this method.

製造方法をその手段とするものである。(Step 1 to solve the problem) In order to solve the problem described in 4-, thermoplastic resin powder is added to the surface layer of the nonwoven fabric web and bonded, thereby creating a flexible texture and excellent surface abrasion resistance. The present invention was arrived at as a result of extensive investigation into the strength of nine fissures. That is, the present invention is characterized in that a thermoplastic resin powder having an average particle size determined by the gap between fibers constituting the nonwoven web is applied to at least one surface layer of the nonwoven web and is adhered to the surface of the nonwoven web. Thermoplastic resin powder having an average particle diameter larger than the gap between constituent fibers of the nonwoven web is evenly applied to at least one surface layer of the nonwoven fabric and the nonwoven web at an application amount of 1 to 30 cJ per 1 r1 of the nonwoven fabric web,
The method for producing a nonwoven fabric is then heated at a temperature below the melting point of the fibers constituting the nonwoven fabric web and at a temperature less than or equal to the melting point of the thermoplastic resin, followed by compression bonding or heating and pressure. It is something to do.

２０で求めた平均値の平方根であられした。In the present invention, the term "gap between the fibers constituting the nonwoven web" refers to the uniform spacing between the net-like fibers constituting the web. The gap was measured by optical microscopic observation, where n =
It was calculated by the square root of the average value obtained in step 20.

8 (1), the temperature should be about 100°C above the melting temperature in advance.
After maintaining the device at a low temperature until it stabilized, the melting rate was determined at a heating rate of 10°C per minute, and the apex of the peak was taken as the melting point (

次の測定方法による。This is because only the surface layer of the nonwoven fabric partially restrains (bonds) the nonwoven fabric web fibers and increases the degree of freedom of the web fibers in the inner layer of the nonwoven fabric web. Even if a thermoplastic resin having an average particle diameter smaller than the gap between the fibers constituting the nonwoven web is applied to the surface layer of the nonwoven web, this thermoplastic resin will enter the gap between the fibers constituting the web, and even the fibers in the inner layer of the nonwoven web will be restrained. The resulting nonwoven fabric behaves as if it were impregnated with resin. Therefore, it is no longer a nonwoven fabric that has a good balance of soft texture, surface abrasion resistance, and tear strength. Specifically, the average particle size of the thermoplastic resin is preferably 30 u to 200 u, more preferably 50 u to 150 u, particularly preferably 70 u to 150 u.

・Jf is desired. This is a thermal zero below 30 μm.
Even if an engineering plastic resin is applied to a nonwoven fabric web, the bonding force between the fibers that make up the nonwoven fabric web will be significantly reduced, and the MIIF plastic resin will enter the inner layer of the nonwoven fabric web, resulting in It behaves as if it has been impregnated and the texture becomes stiff. Also, 200/
Even if a thermoplastic resin exceeding JJ11 is applied, the fibers that make up the nonwoven web will be excessively bonded, and the degree of freedom of the constituent fibers will be restricted, resulting in a stiff texture. be. In addition, (1i, average particle size is

望ましい。A nonwoven fabric made under the conditions described above is one in which a thermoplastic resin is attached to the surface layer of the nonwoven fabric in the cross-sectional direction of the nonwoven fabric, and at least a part of the inner layer of the nonwoven fabric web is bonded with the thermoplastic resin. It is desirable that it be in a free state.
