820, a sheet made of rayon, polyamide, or polyester fibers mixed with low-melting point fibers and fused at intersections is used. These constituent fibers have a fineness of 20 microns or more: the opening of the nonwoven fabric is large.

Some products have a bulky structure to prevent wear, but even with the slightest pressure, they feel sagging or tight, which causes discomfort and sometimes causes skin rashes.

以下、本発明の詳細な説明する。The present invention will be explained in detail below.
肌に接する内層の不織布は、平均太さの１０ミクロン以

トでなくてはならない。Methods for producing nonwoven fabrics of hydrophobic ultrafine fibers include melt blowing, spunbonding, flash spinning, and gllii.
Any method such as the a-splitting method may be used, but it must be entangled or self-fused, have shape stability during use and handling, and be soft.

。As a material having such characteristics, an ultrafine fiber sheet such as that obtained by melt blow spinning of polypropylene is more desirable because it has a small opening, entanglement, self-fusion, and high hydrophobicity. The melt blow spinning method heat-melts the polymer to a low viscosity, discharges it from a nozzle, and tears it with high-temperature, high-speed airflow, making it easy to obtain a nonwoven fabric with an average fineness of 10 microns or less, entanglement, self-fusion, and small openings. be. Thick yarns may be mixed therein, and if the average thickness exceeds 10 microns, the texture will be impaired and the opening will become larger. On the other hand, in the case of melt blowing, when the average thickness is less than 0.1 micron, the fiber length becomes short and the degree of entanglement decreases. This results in a decrease in strength. Therefore, the average thickness is preferably about 0.1 to 10 microns.

良い。The above-mentioned non-woven fabric has morphological stability as it is, but in order to roughly perfect it, it is subjected to water set punching under the conditions of a nozzle diameter of 0.3 mm2, a nozzle pitch of 2.5 III m, and a water pressure of 5 to 15 kq/d. and more effective. Further, embossing may be applied to the extent that the fibers do not fuse together.

In this case, it is preferable that the nozzle diameter Q is 3 mm x, the nozzle pitch is 2.5 mm, and the water pressure is oscillated at 20 to 30 ki/ci.

動を早めても、本発明の使用にはならない。When urinating, it is necessary to quickly transfer urine to the absorbent material. Since we use hydrophobic fibers and a non-woven fabric with small openings, if there are too many, they will not move. The basis weight of the present invention is 30q/Tr1 due to the relationship between micturition temperature and micturition pressure.
It has been found that if it is 2 or less, it moves quickly. After the transfer, the temperature of urination decreases and the pressure during urination disappears, which can result in a non-woven inner layer of disposable diapers with very little urinary retention. However, if the basis weight is less than 5Q/m2, the opening will increase, it will be easy to move, and it will start to move back, so it is preferably 5 to 300/m2. In addition, in the range of the present invention where the fabric weight is high, even if a slight amount of a surfactant such as polyethylene glycol is added to the nonwoven fabric to accelerate the movement of urine, it will not be used in the present invention.
中層の吸収性材料としては、吸収紙、綿状パルプ、高分
子吸収体をそれぞれ例えばベビー用、大人用など使用目
的に合った保水能力に設定する。As the absorbent material for the middle layer, absorbent paper, cotton-like pulp, and polymeric absorbent material are each set to have a water retention capacity suitable for the purpose of use, such as for babies or adults.
外層の防水性シートは、排尿で衣料を汚さないようにす
るため、厚み３〜１０ミクロン程度のポリエチレンフィ
ルム、あるいはムレ感を少なくするため通気性ポリエチ
レンフィルム等を使用する。The waterproof sheet for the outer layer is a polyethylene film with a thickness of about 3 to 10 microns to prevent urine from staining clothing, or a breathable polyethylene film to reduce stuffiness.
特に内層と同じような疎水性極細繊維の不１ａ侑を外層
の防水性シートとして用いると通気性がおり、ムレ感を
解消することができる。In particular, if a waterproof sheet made of hydrophobic ultrafine fibers similar to those used in the inner layer is used as the waterproof sheet for the outer layer, it will have air permeability and eliminate the feeling of stuffiness.
