摘要:
An absorbent layer containing water-absorbing polymeric particles that are surface-treated and that are immobilized by a matrix, formed from a thermoplastic adhesive component, including a thermoplastic polymers and a specific plasticizer, and being free of low weight average molecular weight (e.g. below 1000, or below 2000 or even below 3000 g/mole) tackifiers and plasticizers. The absorbent articles may for example be adult incontinence articles, infant (e.g. baby, toddler) diapers, including training pants, and feminine hygiene articles, such as sanitary napkins.
摘要:
An absorbent article includes a liquid-pervious sheet, an outer covering sheet, and an absorbent structure sandwiched between the liquid-pervious sheet and the outer covering sheet. The absorbent structure includes a liquid-absorbent mixture composed of super-absorbent polymer particles and fluff pulp and nonwoven fabric sheet formed from long fibers of thermoplastic resin. The nonwoven fabric sheet is put in contact, along at least one surface thereof, with the liquid-absorbent mixture and has cross points at which the long fiber sealed together, and a nap height defined by a difference between a thickness measured before a napping test and a thickness measured after the napping test is at least 0.5 mm.
摘要:
A fiber is provided wherein the fiber contains an energy receptive additive. The fiber provides rapid heating when subjected to dielectric energy such as radio frequency or microwave radiation. The energy receptive additive has a dielectric loss of between about 0.5 and 15, preferably between 1 and 15 and most preferably between 5 and 15. The fibers may be crimped, extensible or elastic.
摘要:
Absorbent article such as a diaper, pant diaper, incontinence guard, sanitary napkin, wound dressing or the like comprising a layer of continuous fibers (9), so called tow, which is bonded in points, spots or lines in a bonding pattern (10), but where the fibers otherwise are substantially unbonded to each other. Said layer can either be used as a liquid acquisition layer (5) in the article under the topsheet (2), as a topsheet (12) or as a combined topsheet and liquid acquisition layer (22).
摘要:
A sanitary article which comprises an absorbent layer, a leak-proof sheet and a surface sheet, at least one of the absorbent layer, leak-proof sheet and surface sheet having a porous aggregate of fibers integrated therewith.
摘要:
A tampon having a single layer wrap of fibers attached together by a powder binder. The wrap is embossed around a tampon pledget. The wrap in one embodiment includes a blend of hydrophobic synthetic fibers and hydrophilic cellulosic fibers laminated together with bonding powder. Another embodiment has only hydrophilic cellulosic fibers laminated together with bonding powder.
摘要:
An absorbent product, for example a diaper, comprises an absorbent member (3), for example a pad formed of comminuted cellulose fibres or a superabsorbent polymer, and a particle-bonded nonwoven material (1) having an outer phase (4) that is in an unlofted state and an inner phase (5) that is in a lofted state. The nonwoven may be formed of polyester fibres bonded with a polyester adhesive. The product may also comprise a liquid-impermeable backing sheet (2).
摘要:
A pantiliner consisting essentially of an overwrap and a resilient element. The overwrap is a soft, smooth, compliant, porous material while the resilient element is compressible, conformable, and resilient. The former can be any material commonly used as a topsheet for sanitary napkins while the latter is preferably a mass of moisture insensitive fibers which can be bonded one to another at their points of contact. Preferably, the surfaces of the fibers are hydrophilic. Adhesive attachment means are preferably associated with the pantiliner.
摘要:
A fibrous web, such as a nonwoven liquid-pervious fibrous web, has reinforced marginal portions and an unreinforced medial portion, the fibers of the reinforced marginal portions being at least partially thermally fused or embedded within a cured bonding medium. A process for forming reinforced marginal portions on a fibrous web includes the steps of passing said fibrous web through a pair of nip rollers having heated marginal surface portions and at least partially thermally fusing fibers of the marginal portions, but not the medial portion, of the fibrous web. Alternatively, the method comprises applying a curable medium to the marginal portions of the fibrous web, but not to the medial portion, and curing the curable medium to embed the fibers of the marginal portions within the cured medium. The fibrous web article of the invention may suitably be employed as a liquid-pervious topsheet in an article comprising a substantially liquid-impervious backsheet, such topsheet and an absorbent body disposed therebetween.
摘要:
An absorbent pad containing a nonwoven hydrophilic thermoplastic filamentary microfibrous web as part of the absorbent material is provided. The microfibrous web exhibits good wicking and fluid retention properties.
