た。早急に商品化が望まれている。However, a diaper liner made of a single non-woven fabric such as rayon, cotton, polyester fiber or the like or a composite non-woven fabric thereof cannot be flowed into a toilet because it has no water dissolving property. In addition, when cellulose fibers in the research stage are processed with a binder such as CMC or PVA, the water strength of urine is weak, faeces leak into diapers, and there is a problem in water disintegration and dispersibility in toilets during use, and they are commercialized. It is not at present. In addition, it is the theory that the strength of the urine salt concentration at the time of use is given to the water-absorbent polymer and the non-woven fabric sheet of the cellulose fiber blend, and the water dispersibility is obtained by dispersing in the toilet water. When the water disintegration property increases, the water disintegration property deteriorates, and when the water disintegration property is improved, the strength decreases. A practical water disintegratable diaper liner having a good water disintegration property and a sufficient tensile strength for use has not been developed. The present invention uses a biodegradable material rayon and pulp fiber without using an adhesive to make a water-decomposable sheet, and uses a rayon fiber length of 15 mm or less to satisfy the contradictory conditions of water-decomposability and tensile strength during use. The present invention focuses on a water-disintegrable sheet in which pulp fibers are entangled with rayon fibers by a water jet entanglement method using fibers as a mixed web. Also, when taking out the water-disintegratable diaper liner from the diaper and flushing it to the toilet with feces, in order to prevent that the treatment accidentally pulls both ends of the water-disintegrable diaper liner outwards, causing fiber collapse and feces falling off In addition, a non-water-disintegrable porous sheet is detachably disposed on the outer side opposite to the skin side. Due to the increase of the elderly population, fecal disposal is difficult. It was unpleasant to leave sewage wrapped in feces for bedridden elderly care in urban apartments until the day of garbage collection. Immediate commercialization is desired.

る。In view of the above circumstances, the present invention provides a method of mixing pulp fibers with a fiber length of 15 mm or less using rayon, and mixing the pulp fibers with rayon fibers having an average fiber length of 2.0 mm to 10.0 mm. This is a water-disintegratable diaper liner characterized by using a fiber-blended web as a spunlace sheet by a water jet entanglement method. Further, in the water-disintegratable diaper liner, the above-mentioned diaper liner is disposed on the skin side, and another pulp-based hydrolyzed paper is joined to the outside to form a water-disintegratable diaper liner having two layers. Further, as a measure for preventing inconvenience in the case where fiber collapse occurs due to erroneous treatment when using a water-disintegratable diaper liner, the water-disintegratable diaper liner according to claim 1 or 2 is disposed on the skin side and non-water-disintegrable outside. The porous sheet is detachably arranged.

The direction is preferably 100 g or more. In order to improve the water disintegration, the ratio of the single fiber of the rayon fiber is increased to more than 50%, and the water disintegration is improved by increasing the fineness of the rayon. The quality of water disintegration depends on the enforcement regulations of waste treatment and cleaning (Showa 46

The water-disintegrable sheet layer 1a is the same sheet as the water-disintegratable diaper liner 1 of the embodiment 1 or a water jet entangled spunlace spunlace water-disintegrable sheet having a slightly reduced basis weight. Layer 1a. The pulp-based water-disintegrated paper sheet layer 4 is a layer appropriately using 1 to 4 plies of toilet paper 16 g / m 2 . The water-disintegrable sheet layer 1a and the pulp-based water-disintegrated paper sheet layer 4 are joined by an appropriate method such as a needle punch method, an embossing method, or a water jet entanglement method. The shape and dimensions of the water-disintegratable diaper liner 1 are the same as those in Example 1, but the basis weight is 30% in order to increase the amount of urine absorbed.
And the thickness should be increased by 20%. The mixing ratio of rayon and pulp in the water-disintegrable sheet layer 1a may be substantially the same. The water-disintegrable diaper liner 1 of Example 2 has the same water-disintegrable quality and tensile strength as those of Example 1 described above. By adding the pulp-based water-disintegrated paper sheet 4 to form two layers, the urine absorption during use is improved without increasing the cost and deteriorating the water-disintegrability, and the strength of the water-disintegratable sheet layer 1a on the upper surface is maintained.

えている。In the production method of the present invention, first, the above-mentioned rayon and pulp are mixed, and after wet paper making, a dry web sheet or a flowing cotton dry web sheet is made by a card machine. Next, the fibers in the web are entangled with a water jet to give a sheet having a strength and a soft texture that can withstand use. At this time, depending on the water pressure condition of the nozzle, the water dissolvability (dispersed within 15 times by a voluntary simple test water dissolving graduated cylinder agitation test method) that can be poured into the toilet and the tensile strength that can withstand user use are adjusted. The water jet method is a method developed by the US company Dupont, and there is no damage between fibers and the texture is very similar to knitting,
Since no adhesive is used, the use of a water jet entangled spunlace sheet for wet tissues is increasing.

It is expected that feces will fall off on the way. This embodiment prevents such a disadvantage. FIG. 4 shows a non-water-disintegrable porous sheet 8 removably attached to the outside of the water-disintegratable diaper liner 1 on the side opposite to the skin side. Non-water disintegrable porous sheet 8
Use a knitted fabric, a net fabric, or a non-water-disintegrable sheet in which a large number of holes are perforated using a non-water-disintegrable fiber. The non-water-disintegratable porous sheet 8 can be washed and repeatedly used by holding the end of the non-water-disintegratable porous sheet 8 and holding the water-disintegratable diaper liner 1 in the toilet. The water-disintegratable diaper liner 1 is supported from the lower surface to prevent shape collapse, and the porous unevenness generates air movement between the diaper and the diaper liner, thereby exhibiting an effect of preventing the diaper from being distorted.

てむれ防止の効果をも発揮するAs described above, according to the present invention, (1) rayon fiber of 15.0 mm or less and pulp fiber are mixed without an adhesive to obtain an average fiber length of 2.0 mm to 10.0 mm.
A very convenient water-disintegrating diaper liner that has never been used before, when physically entangled by the water jet confounding method and withstands the actual use strength, when stool is wrapped and flushed down the toilet, it is dispersed in the toilet flow. It is. (2) Since the raw materials used are rayon and pulp cellulose, it is biodegradable, and the decomposition in the toilet tank and in nature proceeds smoothly. (3) Without adhesive, the raw material used is cellulosic fiber, the same chemical composition as cotton underwear, it is not irritating to the skin and is allergic, atopic, and suitable for subjects with bedsores. (4) Water jet entanglement sheet Since it is a manufacturing method, it is soft and has a good texture due to a small amount of fine powder falling off due to the water flow at the time of manufacturing, so that the feeling of use is good. (5) Since the raw materials are pulp and rayon, there is an advantage that the raw material cost is half that of the cotton nonwoven fabric. (6) The non-water-disintegratable porous sheet 8 is a water-disintegratable diaper liner 1.
While supporting the garment from the bottom to prevent shape collapse, the porous irregularities also create air movement between the diaper and the diaper liner, and also exhibit the effect of preventing unevenness.
