The non-loop surface is important from the viewpoint of feel, flexibility and air permeability. The area of one non-thermocompression bonding part is 5mm 2
If it is less than 1, the area of each non-thermocompression bonding part is considerably small, so the loops existing in the non-thermocompression bonding part, and those near the thermocompression bonding part are fused by the influence of heat. In such a state, it becomes impossible to sufficiently function as a loop for engaging with the male member, so that there is a tendency that a sufficient engaging force cannot be obtained. Further, in consideration of the elongation and shape stability after the engagement with the male material and the form stability, the upper limit of the area of each non-thermocompression bonding portion is 35%.

If the single yarn fineness is less than 1 dtex, the strength of the loop that engages with the male hook becomes weak, so the loop is easily cut at the time of detachment from engagement with the male material, the engagement strength, and the durability in repeated use. Is significantly reduced. Also, when a loop is formed by needle punching, due to wear caused by penetration of the needle needle, etc.
The constituent fibers are easily broken, and it is difficult to obtain sufficient engaging strength as a hook-and-loop fastener. On the other hand, if it exceeds 11 dtex,
Although the strength of the filament is sufficient, the rigidity of the loop increases, making it difficult to engage with the male hook.In the case of a relatively low weight, the number of female material loops is relatively reduced, It becomes difficult to engage with male material,
Even in the female material itself, a loop-forming spot tends to occur, and an engaging spot causing a difference in the engaging force is likely to occur.

する。First, a loop is formed on one side of a nonwoven web on which thermoplastic synthetic long fibers are accumulated. As a method of forming a loop, a mechanical entanglement method by needle punching or a method of entanglement by high-pressure liquid flow treatment may be used, and it is possible to entangle the constituent fibers by these methods and simultaneously form a loop on one surface. it can. In particular,
A needle punching method which is excellent in forming a loop can be preferably used. In the case of the needle punching method, a loop is formed on the side where the needle needle enters, that is, on the side opposite to the side where the needle needle is installed, to form a loop surface.

止されているような状態を指している。In this case, when an embossing device including an embossing roll and a smoothing roll is used, the loop surface is arranged so as to contact the embossing roll, and the temperature of the embossing roll is set higher than the temperature of the smoothing roll. After setting, a partial thermocompression bonding process is performed. When the temperature of the embossing roll is lower than the temperature of the smoothing roll, the fibers in the partially thermocompression-bonded portion of the obtained nonwoven fabric for female material are not sufficiently hot-melted / fused, so the adhesion is insufficient. The nonwoven fabric having the shear strength intended by the present invention cannot be obtained, and the nonwoven fabric for female material easily expands and deforms at the time of disengagement. Also, if the temperature of the smooth roll is raised to increase the adhesive strength of the partial thermocompression bonding part, the fibers existing on the non-roll surface are affected by the heat, causing heat fusion, and the entire surface is turned into a film. Anyway, there is a problem that the air permeability decreases and the feel is inferior. The term "affected by heat" as used herein means that the fibers are densified by fusing as obtained when they come in contact with a high-temperature roll set at a temperature near the melting point of the thermoplastic fibers, and thereby prevent fluffing. Refers to such a state.

In this temperature range, it may be appropriately selected according to the linear pressure between the rolls and the processing speed.

ものを得ることができたものである。In the present invention, it is an important element in the present invention that the fibers and loops existing in the non-thermocompression bonded portion are not affected by heat. That is, in the generally known partially thermocompression bonded nonwoven fabric, having higher nonwoven fabric strength and having high air permeability and excellent flexibility are contradictory matters, and these are simultaneously It is difficult to obtain a satisfactory nonwoven fabric. In the manufacturing method of the present invention, the non-woven fabric is firmly pressed only at the partial thermo-compression bonding portion by not giving any heat to the non-thermo-compression bonding portion and making it substantially free of fusion. While having strong strength, the non-thermocompression bonding part maintains a state that is hardly affected by heat, so it is possible to obtain a product that satisfies both of them, combining high air permeability and excellent flexibility. It was done.

とになるため好ましくない。In order to obtain such a nonwoven fabric, the depth of the unevenness of the embossing roll (the difference between the convex and concave portions of the embossing roll) is preferably at least 1 mm, more preferably at least 2 mm. desirable. If it is less than 1 mm, the surface portion of the non-compression-bonded portion is fused by heat conduction from the high-temperature embossing roll, or the loop that plays an important role in the female fastener material is crushed or solidified. However, it has a fatal disadvantage that the engaging force is reduced, which is not preferable.

The measurement was carried out at a tensile speed of 20 cm / min, and an average value of N = 5 of the obtained results was obtained, which was defined as a 5% elongation strength (N). The strength at the time of 5% elongation was measured in both the MD direction and the CD direction. When the nonwoven fabric for a hook-and-loop fastener female material is actually used, the strength is often increased by about 5%. It can be said that it indicates the degree of sex. Further, as for Y (strength at 5% elongation) to be applied to the calculated value of the equation (2), the lower value of the measured values in the MD and CD directions is adopted, and the value of the equation (2) The calculated value was determined.

Then, the center part is stuck with tape to create a cylindrical sample. When the sample is placed on a flat plate and crushed by another flat plate perpendicular to the MD axis, the maximum strength applied to the flat plate is increased by a compression rate of 50 with RTM-500 using Tensilon manufactured by Toyo Baldwin Co., Ltd.
It was measured at mm / min and taken as the MD softness value. The direction of the cut sample was changed, and the compression stiffness value in the CD direction was obtained by the same method. The measurement was performed at n = 5 in each of the MD and CD directions, and the total average value was used as the compression bending resistance and used as an index of flexibility.
