  • Patent number: 11033844
    Abstract: Stabilized air filters formed from mats of crosslinked protein-containing fibers are provided. The fibers are formed into a mat with pores that allow air to pass through while physically filtering particulate matter. The protein in the protein-containing fibers also serves to chemically filter polluted air passed through the filter. Specifically, chemical functional groups from the many amino acids that comprise the protein of the protein-containing nanowire react with certain chemical pollutants (e.g., carbon monoxide and formaldehyde) in order to capture or otherwise neutralize the pollutant. Accordingly, the single fiber mat performs two filtering functions. Methods for making the air filters from crosslinked protein-containing nanofibers are also provided.

  • Patent number: 10807290
    Abstract: This invention involves a new and better solution to the problems associated with the premature softening of PLA filaments in the additive manufacturing of three dimensional articles. It is based upon the finding that poly(lactic acid) filaments with high crystallinity offer much better resistance to heat-induced softening. The crystalline poly(lactic acid) filament of this invention can accordingly be used in the additive manufacturing of three dimensional articles without encountering the problems associated with premature softening, such as poor quality and printer jamming. The crystalline poly(lactic acid) filaments of this invention can also be used in additive manufacturing of three dimensional articles without compromising the quality of the ultimate product, reducing printing speed, increasing cost, or leading to increased printer complexity.

There is also provided a method for manufacturing a web using this fiber bundle. There is also provided a web that is uniform and has excellent soft touch and bulkiness. This is achieved by a fiber bundle with a total denier of 10,000 to 500,000 dtex, obtained by bundling thermoplastic, conjugate, continuous fibers that have a single filament denier of 0.5 to 100 dtex/f and in which the center of gravity of conjugate components varies among the conjugate components in a fiber cross section, wherein the thermoplastic, conjugate, continuous fibers that make up the fiber bundle have a spontaneous crimp of 8 to 30 crimps per 2.

  • Patent number: 9388526
    Abstract: A method of making a fiber comprised of poly(p-phenylene terephthalamide) having monomer groups grafted onto the fiber surface, the method comprising the steps of (i) providing a fiber of poly(p-phenylene terephthalamide) that has been dried to remove adsorbed moisture, (ii) treating the fiber, in a non-polar solvent that will not dissolve the fiber, with a phosphazene base that exhibits a pKa in dimethylsulfoxide of at least 21 so as to generate anions at the amide sites on the surface of the poly(p-phenylene terephthalamide) fiber, (iii) washing the base-activated fiber with an aprotic solvent, (iv) grafting a monomer onto the anion sites so as to introduce reactive functional groups onto the surface of the poly(p-phenylene terephthalamide) fiber, and (v) washing the grafted fiber of step (iv) with a protic solvent to extract any residual base compounds and grafting agents that are unbound to the surface of the fibers.

  • Patent number: 9283125
    Abstract: In a disposable wearing article, a first waist region is elasticized and formed of an inner sheet and an outer sheet. The non-skin-facing side of the outer sheet is formed substantially over its entire area with a plurality of thermocompression-bonded spots regularly and intermittently arranged at predetermined intervals. The outer sheet has non-thermocompressed regions surrounded by a plurality of thermocompression-bonded spots. A fibrous layer lying at least on the outer surface of said outer sheet is formed of thermal adhesive crimped fibers which are bonded together by thermocompression-bonding treatment in the thermocompression-bonded spots. The outer sheet and the inner sheet are bonded to each other by adhesive applied on at least one of respective opposite surfaces thereof so that the crimped fibers in the non-thermocompressed regions may protrude outward in a thickness direction of the outer sheet as the inner sheet contracts in the direction of the transverse axis Q.
