Mouh-Wahng Lee has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9963806
    Abstract: The invention relates to a thermoplastic polyurethane fibers, and process of making the same, where the described fiber has good dyeability, and in some embodiments, good flame retardant properties. Such fibers are made from a composition that includes (a) a thermoplastic polyurethane itself comprising the reaction product of: (i) one or more polyols, (ii) one or more diisocyanates, (iii) one or more chain extenders, (iv) optionally one or more crosslinking agents, and (v) one or more functional modifiers wherein each said functional modifier is a reaction product of an aminodiol and a Bronsted acid.
    Type: Grant

  • Patent number: 9688805
    Abstract: The present invention relates to elastomeric resins, fibers made from said resins, fabrics made with said fibers, and applications and uses for the resins, fibers and fabrics. The elastomer resins of the invention provide high strength fibers and well balanced fabrics with good physical properties and chemical resistance, making them attractive for use in various applications that use elastic fibers and fabrics.

  • Publication number: 20170127741
    Abstract: The invention relates to a fiber excellent in cool contact feeling which is excellent in hand and skin touch and capable of preventing unpleasant feeling in the wet state while also having excellent elasticity. The invention also relates to fabric, clothing, and underwear excellent in cool contact feeling and obtainable by using said fiber as well as the methods of making the fibers and articles thereof.

  • Publication number: 20170029982
    Abstract: Elastic fibers are disclosed which have a relatively flat modulus curve at between 100% and 200% elongation. The fibers can be made into garments having a very comfortable feel. The preferred elastic fibers are made from thermoplastic polyurethane polymers and are made by a unique melt spinning process where the fiber is wound into bobbins at a speed just slightly higher than the melt velocity of the polymer exiting the spinneret.

  • Publication number: 20160053408
    Abstract: The present invention relates to high strength fabrics made thereof from thin gauge constant compression elastic fibers. Elastic fibers are disclosed which have a relatively flat modulus curve, for example between 100% and 200% elongation. Garments made with the constant compression elastic fibers have a more comfortable feel to the wearer. The garments are also resistant to puncture due to the high strength fabric made with the elastic fibers.

  • Publication number: 20110183567
    Abstract: Elastic non-woven fabrics are disclosed which are made in a melt blown process or a spunbond process. The fabric is made from a thermoplastic polyurethane polymer mixed with a crosslinking agent to give high strength elastic non-woven fabric. The crosslinking agent is added to the polymer melt prior to the melt passing through the die which forms the individual fibers. Further processing the non-woven is also disclosed.
