摘要:
A melt-spun polymer fiber is provided having a cross-section and a length. A detectable particulate has a size of less than 31 microns and present in an amount of 2.0 to 50.0 weight percent loadings of metal or 10 to 80 weight percent loadings of radiopaque particles to render the polymer fiber detectable by metal (magnetic) or X-ray detection, alone or in combination with a secondary functional particulate distributed in or on the polymer fiber to render the polymer fiber chemically responsive to a chemical reactant, change in pH or temperature. The detectable particulate and the secondary functional particulate are each independently present in a core, a sheath, or both portions of polymer matrix. A process of detecting a fabric made from such a fiber. The fabric article passes through detector. A signal is collected from the detector indicative of the presence of the fabric article.

Described are improved x-ray and gamma ray radiation protective compositions, fibers, and clothing. Also described are methods for producing lightweight, radiation- shielding, protective textiles for protecting the human body and/or methods of producing radiation-shielding coating materials that can be used for coating textiles.

A composite undergarment fabric has an inner side fabric layer of synthetic yarn and an outer side fabric layer of yarn selected from among moisture-absorbent hydrophilic yarn, synthetic yarn rendered hydrophilic, and combinations thereof, an inner surface of the inner side fabric layer having a non-continuous treatment of durable, water repellent chemical, and the outer side fabric layer being relatively more hydrophilic than the inner side fabric layer. The inner and outer side fabric layers may be formed concurrently by knitting a plaited construction. In another implementation, the composite undergarment fabric has a pseudo plaited construction of a body of hydrophilic material with an inner side surface having a non-continuous treatment of durable water repellent chemical.

The invention provides spandex having an initial CIE whiteness of at least about 95 as measured by AATCC Test Method 110-1994, the spandex comprising an optical brightener selected from the group consisting of an oxazole, a biphenyl, a coumarin, a stilbene, a pyrazolene, a rhodamine, and a fluorescein, or a combination of such members, and an ultraviolet screener selected from the group consisting of a triazine, a benzotriazole, an oxalanilide, a benzophenone, and a bismalonate, or a combination of such members.
摘要:
An absorbent article has a liner adapted for contiguous relationship with the wearer's body, an outer cover in generally opposed relationship with the liner, and an absorbent body disposed between the liner and the outer cover. The absorbent body has an absorbent structure constructed of absorbent fibers and binder fibers activated to form inter-fiber bonds within the absorbent structure. The absorbent structure has a generally unstable configuration and is predisposed to bend toward a generally stable, bent configuration. In a process for making such an absorbent structure, the absorbent structure is airformed, bent to a bent configuration, stabilized in the bent configuration, and then compressed to planarize the absorbent structure.
摘要:
An absorbent article having a liner and an outer cover in generally opposed relationship with the liner. An absorbent body disposed therebetween includes a non-woven absorbent structure having a length, a width and a thickness. The absorbent structure is constructed of absorbent fibers and binder fibers activatable to form inter-fiber bonds within the absorbent structure, with the binder fibers being multi-component fibers in which at leastone binder fiber component has a melt temperature that is lower than a melt temperature of at least one other binder fiber component. The width of the absorbent structure is non-uniform along its length prior to activation of the binder fibers. In another embodiment, the absorbent structure is of unitary construction and the concentration of binder fibers therein is non-uniform along at least one of the length, the width and the thickness of the absorbent structure.
