and in that hydrophilic state of hydrophilic copolymer is dependent on ionisation of said ionisable groups, moieties or monomers; kit and device comprising the material and process for preparation thereof; and use in detecting or sensing microbes or pH.

Provided is a stretchable film having excellent stretchability, excellent air permeability, and an excellent deodorizing property. Also provided is an article including such stretchable film. A stretchable film of the present invention is a film having stretchability, and includes a deodorant. The stretchable film of the present invention is a film having stretchability, and has a deodorization efficiency for each of ammonia and hydrogen sulfide 3 hours after the start of a deodorization test, the deodorization efficiency being measured by a detector tube method, of 10% or more.

Absorbent materials configured to sequester trimethylamine (TMA), absorbent articles made therefrom, related methods of use, methods of measuring a reduction of free TMA, and related methods of making absorbent articles are described.

An adhesive device is capable of releasing fragrances, specifically scent patches. The adhesive device is used in the treatment of side effects associated with incontinence or an ileostomy.

The present disclosure relates to an environmentally friendly sanitary napkin including: a permeable inner sheet configured to come into contact with a skin and allow secretions to pass therethrough; an impermeable waterproof outer sheet having the same size and shape as those of the inner sheet and bonded to the inner sheet by fusion; an absorbent pad fixedly inserted between the inner sheet and the waterproof outer sheet and configured to absorb secretions such as menstrual blood that passes through the inner sheet; and an adhesive pad inserted into an appropriate position between the absorbent pad and the waterproof outer sheet, and provided on the absorbent pad and the lower surface of the waterproof outer sheet, and configured to fix the sanitary napkin by adhesion to the inside of underwear, wherein the inner sheet, the waterproof outer sheet, the absorbent pad and the adhesive pad are degradable in water or are biodegradable.

The environmentally friendly sanitary napkin of the present disclosure is degradable by a large amount of water in a septic tank when flushed down a toilet bowl after use, and is biodegradable in soil, thus preventing environmental pollution problems.

In addition, the environmentally friendly sanitary napkin may exhibit antimicrobial effects against harmful bacteria in the vagina and exhibit an excellent effect on sanitariness by suppressing the generation of odor caused by secretions.

A feminine hygiene pad is disclosed. The pad may include a topsheet comprising a nonwoven web, and a fluid management layer beneath the topsheet. The web may include bicomponent staple fibers having an average denier of 1.5 to 2.5 and a sheath-core configuration, have a basis weight of about 18 gsm to 40 gsm, and a plurality of randomly-distributed inter-fiber bonds wherein sheaths of adjacent fibers are fusion-bonded together without compression. The sheaths may comprise PE and the cores may comprise PET, in a weight ratio of 40:60 to 60:40. The web may be formed predominantly of hydrophobic fibers, or the web may include a blend of hydrophilic fibers and hydrophobic fibers, in a weight ratio of 30:70 to 70:30, wherein fiber hydrophilicity is effected by application of a surface treatment composition. The topsheet may bear an application of an anti-stick agent and/or have a pattern of apertures therethrough.

A disposable diaper includes: a top sheet constituting a use-side surface; a liquid impervious sheet disposed on a back surface side; and an absorbent element interposed therebetween. A moisturizing agent mainly containing glycerin is applied to the top sheet, an application region of the moisturizing agent is an exposed region that can be at least visually recognized directly from a use surface side in an unfolded state of the product, and the exposed region has high concentration application regions Q of the moisturizing agent in at least one of peripheral portions in a front-back direction and peripheral portions in a width direction, and a low concentration application region MZ of the moisturizing agent in an intermediate region between the high concentration application regions.

Disclosed is a particulate water-absorbent resin composition containing at least one selected from the group consisting of a microporous inorganic material, silver, and a silver compound, and a polymer particle, in which the polymer particle contains an inorganic reducing agent.

A method for alignment of a pattern printed on a material for an absorbent article by a rotary printing device, including providing a first composition from a first chamber; providing a second composition including a detectable agent from a second chamber; wherein the first composition from the first chamber and the second composition from the second chamber are supplied to the same anilox roller or directly to the same rotary printing cylinder; and printing the first and second compositions on the material for an absorbent article by a rotary printing cylinder.
