Described are fiber materials having improved malodor scavenger properties and a process for the manufacture of said materials. In particular, described are fiber materials usable in the manufacture of disposable or washable diapers, incontinent products, sanitary napkins and other such hygiene and personal care articles with improved malodor scavenger properties, and to methods of manufacturing such materials. It has been found that the incorporation of, especially nanosized, metal particles and/or a cyclodextrin material into fibers creates a 'reactive' material having excellent malodor scavenging properties. More specifically, it has been found that the presence of nanosized metal or metal alloy particles and/or a cyclodextrin material in a fiber material, preferably a synthetic polymer material and more preferably a synthetic thermoplastic polymer fiber material leads to fiber materials or nonwovens having odor-controlling properties. The fiber material especially is useful in the manufacture of hygienic products like disposable diapers.

Fiber material having improved malodor scavenger properties

Described is a closure element for a container. The closure elements has a sealing element which contains a thermoplastic polymer, and an effective absorbing amount of an unmodified cyclodextrin material. The unmodified cyclodextrin material may be an &#x3b1;-cyclodextrin, &#x3b2;-cyclodextrin, &#x3b3;-cyclodextrin, and mixtures thereof. The sealing element can act as a barrier with respect to permeants, such as aromatic substances, trichloroanisole, aldehydes or ketones and/or impurities from the polymer.

Sealing element for vessel or container closures having improved barrier properties

Described is a packaging material which contains a matrix material coated with a thermoplastic polymer and an effective absorbing amount of a cyclodextrin material. The cyclodextrin material is selected from the group consisting of an &#x3b1;-cyclodextrin, a &#x3b2;-cyclodextrin, a &#x3b3;-cyclodextrin or mixtures thereof. The packing material can act as a barrier with respect to permeants, such as water vapor, aromatic and aliphatic hydrocarbons, monomer compositions and residues, off odors, off flavors, perfumes, smoke, pesticides, toxic materials, etc. The barrier properties of the cyclodextrin material may be altered by modifying the moisture content of the cyclodextrin material prior to incorporating into the matrix material.
