していた。(Problems to be Solved by the Invention) However, in the case of the above-mentioned tape fastener, peeling between the eyebrows becomes a problem.
It peels off into layers. In order to eliminate these delaminations, polyethylene film is laminated to allow the film to penetrate into the inside of the nonwoven fabric. However, when the film penetrates into the inside of the nonwoven fabric, there is a problem in that the tear strength decreases and the tape fastener breaks when worn.

を行った結果、本発明に到達したものである。(Means for Solving the Problems) The present inventors have arrived at the present invention as a result of intensive research to provide a tape fastener base material with less reduction in tear strength and without delamination. be.

る。Specifically, the present invention provides a polyolefin-based nonwoven fabric made of a core-sheath composite fiber having a core component of polyester whose main repeating unit is an ethylene terephthalate unit and a sheath component of polyolefin. The gist of the invention is a tape fastener base material that is bonded under heat and pressure at a temperature below the melting point of the material.

リコールジエチレングリコール等が使用される。The polyester constituting the core component of the core-sheath type composite fiber is a copolyester whose main repeating unit is ethylene terephthalate or ethylene terephthalate as a main component. As the copolymerization component, conventionally known acid components and glycol components can be used, and the acid components include isophthalic acid,
Propylene glycol diethylene glycol and the like are used as the glycol component such as adipic acid.

チレン−酢酸ビニル共重合体等が挙げられる。On the other hand, examples of the polyolefin constituting the sheath component include linear low-density polyethylene, high-density polyethylene, medium-density polyethylene, low-density polyethylene, polypropylene, ethylene-vinyl acetate copolymer, and the like.

を生じる。Next, regarding the ratio of core-sheath components, the polymer weight ratio is 1.
: It is preferable that it is 0.1-5. If the polymer weight ratio exceeds 1:5, the amount of polymer that flows during calendering is too large, resulting in a significant decrease in the tear strength of the nonwoven fabric. On the other hand, when the above weight ratio is less than 0.1, the fibers constituting the nonwoven fabric are mostly composed of polyester fibers, so although there is little decrease in tear strength, the amount of resin filled into the fiber spaces constituting the nonwoven fabric is small. Since the amount is too small, peeling of the nonwoven fabric occurs between the eyebrows.
したがって、１：０．１〜５の範囲内に芯鞘比（ポリマ
ー重量比）があるのが望ましい。Therefore, it is desirable that the core/sheath ratio (polymer weight ratio) be within the range of 1:0.1 to 5.

る方法で、その後。Next, the polyolefin long fiber nonwoven fabric can be efficiently obtained by a spunbond method. That is, using a conventionally known melt spinning apparatus having a core-sheath type composite spinneret, a continuous filament is drawn by an air sucker and then a nonwoven fabric is obtained directly on one collection surface.

を充填させ、低通気度の不織布を得る。Next, calendering is performed at a temperature below the melting point of the polyolefin constituting the sheath component of the polyolefin nonwoven fabric to soften and fluidize the polyolefin constituting the sheath component, thereby filling the fiber spaces constituting the nonwoven fabric with polyolefin resin. , obtain a nonwoven fabric with low air permeability.

のが好ましい。If the calendering temperature is higher than the melting point of the polyolefin, the molten polyolefin resin will adhere to the surface of the calender roll, making it difficult to obtain a stable nonwoven fabric sheet. Furthermore, when pressure is applied above the melting point of the polyolefin resin, since the polymer has good fluidity, the polyolefin resin fills the fiber spaces in all parts, making it paper-like and producing only a nonwoven sheet with low tear strength. Particularly in the present invention, the calendering temperature is preferably 10 to 30°C lower than the melting point of the polyolefin.

る。The tape fastener base material for disposable diapers of the present invention has the following advantages, unlike conventional tape fastener base materials made of polyester or nylon long fiber nonwoven fabric. In other words, in the case of conventional tape fastener base materials, an adhesive is applied to one side and a release agent is applied to the other side, but a film such as polyethylene is placed on both sides to prevent these agents from penetrating the other side. It is laminated.

It is possible to penetrate the back surface by coating the above chemicals.In order to achieve this, 1 air permeability test method JIS L-

ができる。(Function) According to the present invention, by calendering a long-fiber nonwoven fabric made of a core-sheath composite fiber using polyester as a core component and polyolefin as a sheath component at a temperature below the melting point of the polyolefin that constitutes the sheath component. It is possible to obtain a tape fastener base material that is free from delamination and exhibits less deterioration in tear strength.
この理由について１本発明者らは９次のように推察して
いる。The inventors of the present invention speculate as to the reason for this as follows.
鞘成分にポリオレフィンを用いた不織布をポリオレフィ

オレフイン成分が流動して不織布を構成する繊維間隙が
充填される。ところが１ポリオレフイン樹脂については
、完全に溶融していないため、その結合は弱いもので、
外力が付加されると、その結合が容易に解除されるもの
である。By calendering a nonwoven fabric using polyolefin as a sheath component at a temperature below the melting point of the polyolefin, the polyolefin component flows and fills the gaps between the fibers that make up the nonwoven fabric. However, 1 polyolefin resin is not completely melted, so its bond is weak.
When an external force is applied, the connection is easily released.

することが可能であるからである。Therefore, the flexibility of the fabric of the one-tape fastener base material remains, and it is thought that there is little decrease in tear strength. Also 1
One of the reasons for the low delamination is that the nonwoven fabric of the present invention is made of core-sheath composite fibers, and there is a large difference in melting point between the polymers constituting the core component and the sheath component. This is because it is possible to appropriately select temperature conditions that allow fiber-to-fiber bonding without completely converting the material into plastic.
