A process is provided for making a soft, high density, absorbent material with improved characteristics. A web is formed from material that includes a mixture of cellulosic fibers and synthetic polymer fibers. Then, the web is preferably compacted and embossed at an elevated temperature to further increase the web density and preferably to also create liquid-stable bonds between the synthetic polymer fibers and the cellulosic fibers in spaced-apart regions of the web.

A process for making a unitary fibrous structure comprises steps of: providing a fibrous web comprising a plurality of cellulosic fibers randomly distributed throughout the fibrous web and a plurality of synthetic fibers randomly distributed throughout the fibrous web; and causing co-joining of at least a portion of the synthetic fibers with the cellulosic fibers and the synthetic fibers, wherein the co-joining occurs in areas having a non-random and repeating pattern. A unitary fibrous structure comprises a plurality of cellulosic fibers randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers distributed throughout the fibrous structure in a non-random repeating pattern. In another embodiment, a unitary fibrous structure comprises a plurality of cellulosic fibers randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers randomly distributed throughout the fibrous structure, wherein at least a portion of the plurality of synthetic fibers comprises co-joined fibers, which are co-joined with the synthetic fibers and / or with the cellulosic fibers.

An absorbent article comprising a nonwoven fibrous structure comprising a plurality of synthetic fibers. The synthetic fibers may be associated with one or more hydrophilizing agents. A process for making the nonwoven fibrous structure involves association of the synthetic fibers with one or more hydrophilizing agents.

A tobacco solution atomizing device for electronic cigarette is disclosed the device comprises an atomizer installed in a fixing sleeve; a suction nozzle component and electrode connectors coupled on respective ends of the fixing sleeve, wherein the electrode connectors comprises a positive electrode connector and a negative electrode connector; the atomizer comprising a glass fiber tube, a glass fiber yarn, a heating coil, a cotton cloth layer and a synthetic fiber layer, wherein the glass fiber yarn is insert into the heating coil which is then located inside the glass fiber tube; the ends of the glass fiber silk and two wires which are used to electronically connect the heating coil to the positive and negative electrode connectors extends outward through the glass fiber tube; the cotton cloth layer enwraps the outside wall of the glass fiber tube and reveal ends of the glass fiber yarn are pressed tightly between the cotton cloth layer and the glass fiber tube; a synthetic fiber layer is filled within the annular shape space between the cotton cloth layer and the fixing sleeve for holding the tobacco solution.

A method for forming a nonwoven fibrous structure comprising a plurality of synthetic fibers. The method employs a hydrophilizing agent. The synthetic fibers may associate with one or more hydrophilizing agents.

An anti-microbial and / or anti-fungal synthetic fiber that comprises various thermoplastic polymers and additives in a bi-component form in either a core-sheath or side-by-side configurations. The anti-microbial synthetic fibers comprise inorganic anti-microbial additives, distributed in certain areas to reduce the amount of the anti-microbial agents being used, and therefore the cost of such fibers. The fibers can incorporate anti-microbial additives so that they are not removed by repeating washing in boiling water and in dry clean cycles and become ineffective and conversely enhance access to the additives by washing or the like. The fibers comprise high tenacity polymers (e.g. PET) in one portion and hydrolysis resistance polymers (e.g. PCT) in another portion with the additives. The fibers can further be blended with non-anti-microbial fibers such as cotton, wool, polyester, acrylic, nylon etc. to provide anti-microbial finished fabrics. In one such embodiment, binder fibers are used which are mixed with other fibers.

The present invention provides a yarn with antimicrobial effects. The antimicrobial antifungal effect of the yarn is derived from nanosilver particles (diameter between 1 and 100 nm) which are adhered to the yarn. The yarn contains fibers which are made of cotton, linen, silk, wool, leather, blending fabric, synthetic fiber, or any combination thereof. The yarn can be used to make cloth to be used particularly for treating patients with burns or wound. The cloth made from the antimicrobial yarn can be further used to make clothes such as underwears, socks, shoe cushions, shoe linings, bed sheets, pillow cases, towels, women hygiene products, laboratory coats, and medical robes. The present invention also provides a method for making the antimicrobial yarn.

The embodiments provide an absorbent garment, such as a disposable diaper, incontinent pad, sanitary napkin, and the like, that has an absorbent core that provides for a long term dryness profile. The dryness profile reflects real world long term usage of absorbent products. Such new absorbent garments can be constructed with absorbent cores containing synthetic fibers and super absorbent particulates.

A nonwoven fibrous structure comprises a plurality of synthetic fibers. The synthetic fibers may be associated with one or more hydrophilizing agents. A process for making the nonwoven fibrous structure involves association of the synthetic fibers with one or more hydrophilizing agents.
