Problems solved by technology

[0007] However, the upper sheet disclosed in Patent Document 1 must undergo a special bleaching treatment for the bleaching of raw cotton fibers, and even if the special treatment is performed, the natural oils and fats have to be reduced, and furthermore, due to the , using the water washing effect of the water flow exchange process, the oil has to be reduced. As a result, the water resistance is not sufficient, the adhesion phenomenon caused by the residual liquid on the surface cannot be sufficiently prevented, and the excretion fluid absorbed cannot be fully concealed.
[0008] In addition, there is a problem that the water repellency of the upper sheet disclosed in Patent Document 1 depends on the remaining amount of natural oils and fats adhering to the raw cotton, so if a high proportion of cotton fibers is added to maintain the properties of cotton fibers, the water repellency will decrease. , the reduction in the concealment of the adhesion and absorption of excreted fluid due to surface residue becomes more significant
[0009] Furthermore, there is a problem that it is difficult to finely adjust waterproofness and impart partial waterproofness in the upper sheet disclosed in Patent Document 1.

Embodiment

[0071] manufacturing with Figure 1 ~ Figure 3 Absorbent articles having the same structure, except for the constituent fibers of the upper sheet and the conditions of whether or not to apply a water repellent were used as Examples and Comparative Examples 1 and 2. Meanwhile, a conventional product was made into comparative example 3. Table 1 shows the manufacturing conditions of the absorbent articles of Examples and Comparative Examples 1-3. The cotton fiber in the table is bleached cotton, and the synthetic fiber is polyethylene / polypropylene composite fiber (denier: 5.6 dtex). An oil agent mainly composed of a stearic acid compound is used as a water repellent.

Abstract

The present invention provides an absorbability article, having an upper sheet material made of cotton fibre with a good skin feel, and capable of ensuring sufficient waterproofness of the upper sheet material and preventing the surface from residual liquid. Said upper sheet material is made of hydro-entangled nonwoven fabric which is composed of 40-100 wt% cotton fibre and 60-0 wt% synthetic fiber. The nonwoven fabric is provided with a plurality of through openings, and waterproof agent is coated on one side or two sides. A water absorption degree (JIS L 1907Byreck method) of a skin contact surface of the sheet material is set 0-5mm.

Description

technical field [0001] The present invention relates to a disposable absorbent article such as a sanitary napkin, a panty liner, a urine absorbent liner, a disposable diaper, etc. for absorbing menstrual blood and leucorrhea. Background technique [0002] Currently, as absorbent articles such as panty liners, sanitary napkins, and incontinence pads, liquid-impermeable back sheets such as polyethylene sheets or polyethylene sheets laminated with non-woven fabrics, and non-woven fabrics are used. Or an article in which a compression-recoverable absorber made of cotton-like pulp or the like is sandwiched between a liquid-permeable upper sheet such as a liquid-permeable plastic sheet. [0003] Since the upper sheet forms a skin-contacting surface, it is required to be soft, provide a dry skin feeling even after excretion is absorbed, and be less irritating to the skin. As raw materials satisfying such demands, synthetic fiber nonwoven fabrics and resin mesh fabric sheets are wi...
