維が用いられている。2. Description of the Related Art A nonwoven fabric formed by entwining a fibrous web with a high-pressure water stream is usually called a spunlace nonwoven fabric,
This spunlaced nonwoven fabric and its manufacturing method have been known for a long time without giving any examples. Further, regarding spunlaced nonwoven fabric having a large number of fine aperture patterns and its manufacturing technique, for example, Japanese Patent Publication No. 56-25547.
JP-A-63-243360. Water-absorbent fibers such as wood pulp fibers, cotton fibers or rayon are generally used for spunlaced nonwoven fabrics applied to wet tissues, towels, sanitary materials and the like.

らないという問題点がある。However, the spunlaced non-woven fabric made of the above-mentioned water-absorbent fiber is suitable for disposable wet tissues and towels because it is soft and has a good feel to the touch and is highly water-absorbent. Because of its low strength, it often breaks during use, and there is a problem in that the basis weight of the fiber must be increased to improve this easy breakability.

As disclosed in Japanese Patent Application Laid-Open No. 4-136254 or Japanese Patent Application Laid-Open No. 4-136254, this can be solved by interposing a net-like sheet or synthetic fiber card web on the fibrous web and performing a water stream treatment. However, such a reinforcing method merely improves the tensile strength of the low basis weight spunlaced non-woven fabric, and cannot form a spunlaced non-woven fabric having an arbitrary pattern.

な単純なものとなる。Further, the formation of a conventional patterned spunlaced nonwoven fabric pattern depends on the support of the fibrous web at the time of water treatment, as shown in, for example, Japanese Patent Publication No. 56-25547, and thus the formed pattern is It will be as simple as a wire mesh.

High-pressure columnar water treatment is applied from above, and the water-absorbent fiber web on each filmed portion of the spunbonded nonwoven fabric is moved and the water-absorbent fiber web is entangled with the spunbonded nonwoven fabric between the film-forming portions to spunlace. The above-mentioned problems were solved by using a non-woven fabric.

A spunbonded non-woven fabric obtained by melt-spinning a thermoplastic polymer that melts into a resin at a relatively low temperature, for example, polypropylene, polyethylene, an ethylene vinyl acetate copolymer, or a composite of two kinds of these polymers and melt-spinning by a spunbond method. preferable. And, it is convenient that the spunbonded nonwoven fabric has a relatively low fabric weight of about 15 to 50 g / m 2 . When the basis weight is 15 g / m 2 or less, it is difficult to form a water-impermeable film portion by hot embossing, and when the basis weight is 50 g / m 2 or more, patterning by heat embossing becomes unsmooth. Not only that, the water absorbency and flexibility of the spunlaced nonwoven fabric are impaired, which is not preferable. A polypropylene spunbonded nonwoven fabric having a basis weight of 15 to 30 g / m 2 is preferable in consideration of economy and ease of embossing.

の多数によって模様を発現させるものである。The film-formed portion of the spunbonded nonwoven fabric formed by hot embossing is formed into a film when a water-absorbent fiber web is superposed on the spunbonded nonwoven fabric and a high-pressure water stream is applied from the water-absorbent fiber web side. The water-absorbent fibers located above the film-forming portion are moved in all directions by blocking the passage of the water flow in the portion, thereby creating openings in the water-absorbent fiber web, and a pattern is developed by a large number of these openings. It is what makes me.

形成するとよい。Therefore, if one of the film-forming portions of the spunbonded nonwoven fabric formed by hot embossing is too small, the texture will be poor, and if it is too large, the fibers on it will not move in all directions. .
The size of the film-formed portion suitable for forming a clear opening in the water-absorbent fiber web and expressing a clear pattern by a large number of the openings has a diameter of about 1 to 10 mm and an area of 0.8 to 80 mm. About 2 and the distance between the adjacent filmed portions is preferably about 2 to 5 mm. The shape of the filmed portion may be circular, rectangular, polygonal, or the like, and a large number of these point-shaped filmed portions may form an arbitrary pattern.

となり鮮明な開口が発現しなくなる。The water absorbent fibrous web to be laminated on the spunbonded non-woven fabric has a fineness of 1 to 2 denier and a fiber length of 10 to 60 mm in consideration of water treatment.
Rayon's card web is preferred. The basis weight of the water absorbent fibrous web to be laminated on one surface of the spunbonded nonwoven fabric is preferably in the range of 15 to 50 g / m 2 . When the basis weight of the water-absorbent fiber web is less than 15 g / m 2 , not only the web is disturbed by the water flow treatment to make the openings unclear but also the water absorbency of the spunlaced nonwoven fabric is lowered. Further, the basis weight of the water-absorbent fiber web is 50 g / m 2
When it is larger than the above range, the movement of the fibers on the film-formed portion is not smooth, and a clear opening is not developed.

The water pressure at the time of water flow treatment suitable for is 30 to 90 kg / cm 2 . If the water pressure is too high, not only the texture will be disturbed, but also water flow lines will appear and the flexibility will be impaired.

に所望の用途に適した吸水性と柔軟性を与える。[Function] The spunbonded non-woven fabric having a pattern with a large number of filmed portions increases the tensile strength of the spunlaced non-woven fabric and spunbonds the superabsorbent fibrous web layer at the time of water flow treatment from the superposed water absorbent fibrous webs. The filmed portion of the non-woven fabric develops an exposed opening pattern. The water absorbent fibrous web layer then imparts to the spunlaced nonwoven a water absorbency and flexibility suitable for the desired application.

適となる。As described above, the spunlaced non-woven fabric with a pattern according to the present invention is embossed, and the heated portion is melted to form an arbitrary pattern due to a large number of filmed portions having a diameter of about 1 to 8 mm. Formed basis weight 15
On at least one surface of the spunbonded nonwoven fabric to 30 g / m 2, the basis weight 10 to 50 g / m 2 of absorbent fibrous webs superposed with water treated water-absorbing fibrous web side is given, the film moiety on The water-absorbent fibrous web located at is entangled with the spunbond nonwoven fabric and the water-absorbent fibrous web by the water flow, and an opening pattern is formed on the surface of the entangled water-absorbent web by the film forming portion of the spunbond nonwoven fabric. It has a higher strength than conventional water-absorbent spunlaced nonwoven fabrics, and the presence of numerous openings forming a pattern on the surface of the water-absorbent web layer causes unevenness on the surface of the water-absorbent web layer. It is applied and the wiping property is improved. Therefore, it is convenient as a cleaning sheet such as a wet tissue or a wiper, and since the large number of openings enhances the quality of the spunlaced nonwoven fabric as a pattern, it is suitable for various sanitary materials and packaging materials requiring water absorption.

できる。Moreover, as described above, a spunbonded non-woven fabric embossed to form a pattern of a large number of film portions is used as a reinforcing base fabric, and a water-absorbent fiber web is laid on at least one surface of the nonwoven fabric to absorb water. Since it can be obtained by subjecting the fiber web to water treatment,
A spunlaced nonwoven fabric with a pattern can be efficiently manufactured at low cost, and the pattern formed on the spunbonded nonwoven fabric can be exhibited in the water-absorbent fiber web layer.
