The present invention provides an electret fiber sheet having superior recovery of airflow volume by heat treatment and having high air permeability. The electret fiber sheet of the present invention is a nonwoven fabric formed from long fibers that are formed from a thermoplastic resin and have an average single fiber diameter of 0.1 to 8.0 m, wherein a bulk density of the nonwoven fabric is 0.05 to 0.30 g/cm.sup.3 and the long fibers contain a crystal nucleating agent at 0.005 to 1.0% by mass.

A spunbond non-woven fabric includes a plurality of fibers. The fibers are formed from a polymer blend that includes at least one first polymer and at least one second polymer. A melt flow rate of the at least one first polymer is greater than a melt flow rate of the at least one second polymer, and the melt flow rate of the at least one second polymer is about 9 g/10 min to less than 18 g/10 min. The blend may include a percentage by weight of the second polymer that is greater than a percentage by weight of the first polymer.

A fiber aggregation contains fiber containing a thermoplastic resin, each of the fiber being mutually joined and aligned.

A head cover that can be worn by health care professionals is provided. The head cover includes an anterior portion with a height h, a posterior portion with a height h.sub.2, at least one side portion or panel which may be shaped and sized so as to connect the anterior portion of the head cover and the posterior portion of the head cover, and where the at least one side portion has a contoured section t that forms all or a portion of a bottom edge of the side portion and that is shaped and sized so as to cover the ears, scalp, and sideburns of a user as required by AORN guidelines while also remaining clear of a user's eyes and field of vision.

A wettable SMS material for personal protective equipment, such as a SMS fabric that has been treated to improve the wettability and absorbency properties of the SMS fabric is provided. A treated SMS fabric for personal protective equipment can retain its durability, breathability, and comfort, and may also provide the fabric with wettability and absorption properties. An article for personal protective equipment formed from a wettable SMS fabric is also provided.

A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.
