Publication number: 20130122772Abstract: A nonwoven fabric is provided having a plurality of semi-crystalline filaments that are thermally bonded to each other and are formed of the same polymer and exhibit substantially the same melting temperature. The fabric is produced by melt spinning an amorphous crystallizable polymer to form two components having different levels of crystallinity. During spinning, a first component of the polymer is exposed to conditions that result in stress-induced crystallization such that the first polymer component is in a semi-crystalline state and serves as the matrix or strength component of the fabric. The second polymer component is not subjected to stress induced crystallization and thus remains in a substantially amorphous state which bonds well at relatively low temperatures. In a bonding step, the fabric is heated to soften and fuse the binder component. Under these conditions, the binder component undergoes thermal crystallization so that in the final product, both polymer components are semi-crystalline.Type: ApplicationFiled: January 11, 2013Publication date: May 16, 2013Applicant: FIBERWEB, INC.Inventor: Fiberweb, Inc.

Patent number: 8241747Abstract: Thermoplastic polyolefin polymer composition, polymer chip, fiber, woven or nonwoven fabric, film, closures, laminates can comprise a polymer, a polymer and a nonvolatile polymer-compatible carboxylic acid. Thermoplastic polyolefin polymer composition can also comprise a polymer, a cyclodextrin-modified polymer and a nonvolatile polymer-compatible carboxylic acid. The carboxylic acid moiety of the polymer composition can react with basic materials in the polymer environment and reduce release of the basic material. The cyclodextrin can act to absorb or trap other contaminants or odors in the environment.Type: GrantFiled: August 26, 2009Date of Patent: August 14, 2012Assignee: Cellresin Technologies, LLCInventors: Willard E. Wood, Neil J. Beaverson

Publication number: 20120190264Abstract: A self-adhesive fiber mat may include glass and/or polymer fibers and bi-component fibers intermixed therewith. The bi-component fibers may include a core material and an outer material surrounding the core material. The outer material may have a low melting point temperature relative to the core material that may soften when exposed to heat enabling the bi-component fiber to bond with fibers and/or surfaces adjacent to the bi-component fibers. Alternatively, the self-adhesive fiber mat may use a heat sensitive resin (bonding resin) as a binder instead of, or in addition to, the bi-component fibers. The heat sensitive resin may bind the fibers together and may also bond the self-adhesive fiber mat with an adjacent film or sheet. Bonding between the film or sheet and the self-adhesive fiber mat may occur as a result of the bi-component fibers or heat sensitive resin being exposed to heat and/or pressure.Type: ApplicationFiled: January 24, 2011Publication date: July 26, 2012Inventors: Shamsheer Mahammad, Souvik Nandi, David Earl Weller, JR., John P. Blanchard
