摘要： The present invention relates to a method for a superabsorbent polymer. The preparation method controls the time from the addition of a foaming agent to the initiation of a polymerization reaction, thereby forming an appropriate pore structure in a superabsorbent polymer. The superabsorbent polymer produced through the preparation method can exhibit a remarkably improved absorption rate while exhibiting excellent absorption performance.

摘要： An enzyme-degradable system for undergarments and feminine hygiene articles works to decompose the undergarments and feminine hygiene articles upon being triggered by bodily fluids, such as urine. The undergarment or feminine hygiene article comprises an absorbent core, an inner sheet of biodegradable material, and an outer sheet of biodegradable material. The core includes at least one of the following: a cellulose material, a wood pulp, a biodegradable and bioactive thermoplastic aliphatic polyester derived from renewable resources (polylactic acid plastic—PLA), and a superabsorbent polymer (SAP). The inner and outer sheets comprise a plant based cellulosic nonwoven material. The cellulase enzyme decomposes the absorbent core, the inner sheet, and the outer sheet upon contact with a bodily fluid. The cellulase enzyme may include DIS-1018 Cellulose-AN, a pH buffer, and additives. Fasteners made from a resilient, biodegradable material help secure the undergarments and feminine hygiene articles to the body.

摘要： There is provided an absorbent article with its front-surface sheet composed of cotton fibers by which liquid reversion is prevented and water retention on the front-surface sheet is minimized. An incontinence pad 1 is provided that is configured to absorb urine at medium or more volume that is 20 cc or more. A front-surface sheet 3 is formed of a spunlace nonwoven fabric 100 wt % of which is composed of cotton fibers and which is coated with a water repellent agent, and has, at least at a portion corresponding to an excreting hole, numerous front-face/back-face penetrating openings 10 that are longer shaped in the longitudinal direction of the incontinence pad 1. The cotton fibers form numerous longitudinal streaks 11 and numerous lateral streaks 12, the longitudinal streaks extending along the longitudinal direction of the incontinence pad 1 and being formed with an interval in the width direction of the incontinence pad 1, and the lateral streaks extending along the width direction of the incontinence pad 1 and connecting together the longitudinal streaks formed with an interval in the longitudinal direction of the incontinence pad 1. The openings 10 are formed within portions surrounded by the longitudinal streaks 11 and the lateral streaks 12. The longitudinal streaks 11 have more fibers and are formed at a higher density than the lateral streaks 12.
