Description of the Related Art A surface fastener is usually composed of a pair of hook surfaces (engaging surface, male material) and loop surface (engaged surface, female material) and is used as an engaging tool for surface-pressing and fixing both. Has been. Since the engaging force (bonding strength) due to the entanglement is used, it is used for various purposes as a simple fastener that can be repeatedly used. For example, it is used in daily life applications such as surgical gowns, diaper covers, and hospital curtains, and in industrial material applications, it is used for fixing automobile interior materials and tunnel waterproofing work by taking advantage of its excellent two-dimensional anti-slip property. . A woven or knitted fabric or a non-woven fabric is generally used as the female material for the surface fastener, and various female materials for the surface fastener using the non-woven fabric have been proposed. For example, (1) two types of multifilaments are mixed by a fluid disturbing treatment, and a multifilament yarn having a large number of loops, coils, etc. on the surface is inserted into a woven fabric (Japanese Patent Laid-Open Publication No. 4 (1998) -26498)

Although there is no problem with the engaging force, the process is complicated and expensive, so it cannot be said that it is necessarily suitable for disposable articles. That is, an inexpensive surface fastener female material suitable for a disposable article, for example, a fastening material for a disposable diaper, which does not require a very strong engaging force and does not require durability with the number of engagements of several times, is still available. The current situation is not. The present invention has been made in view of the above problems, and is a thin surface fastener using a fiber laminate having excellent breathability and engaging properties, which is simple, has excellent flexibility and texture, and is inexpensive. The purpose is to provide disposable articles.

It means a long fiber non-woven fabric produced by having a spinning process, a fiber web forming process and a bonding process.
The long fiber means a fiber spun by a spinning method excluding a special method such as melt blowing, for example, a melt spinning method, a solution spinning method, a flash spinning method, or the like. For example, various non-woven fabrics such as spun-bonded non-woven fabrics and needle-punched non-woven fabrics using the long fibers can be mentioned.

的にも好ましい。Manufacturing Method The manufacturing method is not particularly limited, but a method including a web forming step and a bonding step can be mentioned. As a web forming method, there are a spunbond method, a flash spinning method and the like. The fibers of the non-woven fabric manufactured by the spunbond method according to the usual method are arranged in a substantially straight line,
The single fiber curvature described below is about 1.0 to 1.05, and when used as it is as a surface fastener female member, the engaging force is insufficient and does not function, but it is processed into a meandering fiber shape as described later. By doing so, a practical engagement force can be expressed. Further, the long fiber non-woven fabric produced by the flash spinning method has a smooth surface and is dense and therefore has no engaging property, and is not suitable for a female surface fastener in terms of cost. Further, as a bonding method, there are an adhesive method, a heat bonding method and the like. The adhesive method is a method of fixing the entanglement points of fibers with an adhesive, and although the obtained range of texture and physical properties is wide, the processing cost is extremely high and is not suitable for the present invention. The thermal bonding method is a method of partially softening and melting the fibers themselves to bond the fibers to each other. The thermal bonding method of bonding the heated two nip rolls, for example, between the embossing roll and the flat roll is a thin nonwoven fabric. Since high-speed and stable joining is possible, it is preferable in terms of quality and cost.

の平均値を算出した。(2) Single Fiber Curvature In the present invention, the single fiber curvature is an index showing the degree of meandering of the fiber, and is a linear distance (L) of at least 1 mm connecting any two points of the fiber. , The ratio S / L of the actual fiber length (S) between any two points is meant. The single fiber curvature can be changed depending on the size and shape of the mating male material when the long fiber nonwoven fabric is used as the female material of the surface fastener, but 1.2 or more is preferable because a stable engaging force can be obtained, 1.3 or more is more preferable. When the single fiber is linear, it is 1, and the higher the value is, the more meandering the fiber is. In the present invention, a surface observation photograph magnified about 40 times with a microscope is taken, and the curvature of 50 single fibers arbitrarily selected from the width of the fibers contained in the arbitrarily selected frame of 1 cm x 1 cm is calculated and averaged. The value was calculated.

とができる。There are no particular restrictions on the method for obtaining the long fiber laminate having such a single fiber curvature (meandering), but for example, a method of bending the fibers by applying cooling air in the spinning step or forming a web. In addition to the method of reciprocating the comb-shaped material in the lateral direction and bending in the step, there are methods such as kneading and stretching after the bonding step. Among them, the stretching method can easily and efficiently and stably obtain a laminate composed of meandering long fibers. For example, it may be uniaxially stretched in the longitudinal direction (direction in which the fibers are flowing), transversely (direction perpendicular to the longitudinal direction), or biaxially stretched in both directions. As a stretching method in the transverse direction, a nonwoven fabric may be developed by pressing with a hot roll, in addition to the tenter stretching method. As the stretching conditions, the stretching ratio is 1.4 to 4 times in the longitudinal uniaxial stretching, the stretching temperature is 100 to 140 ° C., and the nip roll interval is 0.
It is preferably 5 to 10 times. In the transverse uniaxial stretching, the stretching ratio is preferably 1.2 to 3 times and the stretching temperature is 100 to 140 ° C.
When biaxially stretching in both directions, the stretching ratio is 1.4 in the machine direction.
-4 times, 1.2 to 3 times the draw ratio in the transverse direction, the stretching temperature is 100 to 140 ° C in the longitudinal stretching, 20 to 140 ° C in the transverse stretching, and the nip roll interval in the longitudinal stretching is 0.5 of the original width. It is preferably 10 to 10. 2. Surface fastener In the present invention, the surface fastener is (I) JIS-L-
Items to which 3410 is applied (limited to those made of synthetic fibers),
And (II) means the same thing as (I) except that the resin is produced by injection molding. As the surface fastener male member to be joined to the surface fastener female member of the present invention, JIS-L-
Also included are hook tapes, mushroom tapes and tapes having the same shape as those defined by 3410, and those obtained by appropriately combining them. The female member of the surface fastener of the present invention means a member of the surface fastener joined to the above-mentioned male member, and a loop type and a braided and raised type can be mentioned as typical examples. By using the above fiber laminate,
It is possible to obtain a female member for a surface fastener having excellent breathability and flexibility without fibers falling off. II. Disposable Article The disposable article in the present invention means a disposable sanitary material, medical application, etc. in which the number of times of engagement such as a diaper, a headrest sheet, a mask, a disposable surgical gown, a bandage, and a tourniquet is about several times. By using the female surface fastener material of the present invention, a disposable article can be produced at low cost.
