Abstract: Circular knit, elastic fabrics (10) of at least one of single jersey, French terry, and fleece are disclosed that include a bare elastomeric material (12) plated with spun and/or continuous filament hard yarns (14) . The circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are manufactured by a method that does not require a dry heat setting step. The method requires drafting the bare elastomeric material no more than about 2.5x its original length when knitting to form the circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece.

Abstract: The present invention relates to the combination of a tension gate (18) and an air shield (24) in the relax zone of a fiber production process. The combination provides a synergistic effect over an air shield (24) alone, or a tension gate (18) alone, or the added effect of both a tension gate (18) and an air shield (24). The air shield (24) is a plate like structure with or without perforations. The air shield plates (26, 28) are placed in close proximity to a pair of rolls (20, 22) following the tension gate (18). The plates (26, 28) are positioned inside of the threadline between the pair of rolls (20, 22). The tension gate (18) can be one or more air drag devices, one or more liquid drag devices, or one or more solid surface contact devices, or a combination of any of the above. The apparatus and the process for using the apparatus is disclosed and claimed.

Abstract: The invention provides a process for making permanent stain resistant polyamide carpets with light color. The process comprises dyeing a low amine end and cationic dyeable polyamide carpet with acid dyes, and imparting stain resist compositions onto the carpet. In addition to stain resist compositions, a fluoro-chemical is also applied to improve soil resistance. The resulted carpet displays a built-in permanent anti-stain and anti-soil resistance after many shampoo-washes.

Abstract: A process for making a solution of perfluorosulfonated ion exchange polymer is disclosed. The process involves heating a slurry containing a perfluorosulfonated ion exchange polymer resin, an organic ether compound and water in a mechanically agitated pressurized vessel to an elevated temperature, so as to totally dissolve the resin in the solution. The perfluorosulfonated ion exchange polymer solution is recovered, and the water and the organic ether compound are removed from the solution. A perfluorosulfonated ion exchange polymer resin remains, which can be coated onto a fabric, or converted into a film which can be laminated onto a fabric. The resulting fabric forms the basis for a chemical and/or biological agent barrier for use in certain types of apparel.

Abstract: Phosphonite ligands, catalyst compositions containing such ligands and a hydroformylation process using such catalyst compositions involving a bidentate phosphonite ligand having the structure represented by formula (I) wherein the Ar groups are either the same or different unbridged organic aromatic groups such as substituted or unsbustituted phenyl, substituted or unsubstituted naphthyl, mixtures thereof or the like are disclosed. The ligands in combination with a Group VIII metal or Group VIII metal compound are particularly useful in a hydroformylation process for reacting an ethylenically unsaturated compound to produce linear alkenals at high selectivity.

Abstract: The present invention relates to methods for making polyamide filaments, such as nylon 6,6, having high tensile strength. The invention also relates to yarns and other articles formed from such filaments. The invention is particularly useful for providing a filament yarn with tenacity equal or superior to the prior art at high spinning process speeds while retaining the ability to draw the yarn. The invention further relates to providing a filament yarn extruded from a delustered or pigmented polyamide polymer.

Abstract: The invention provides a method for knitting fabric with bare spandex comprising: providing bare spandex yarn; providing hard yarn; drafting the bare spandex; knitting fabric from the hard yarn and the drafted bare spandex with the hard yarn and the drafted bare spandex plated in every course; and contacting the knit fabric with a continuous phase aqueous solution under conditions of temperature and pressure for a time sufficient to set the bare spandex without heating the knit fabric on a tenter frame above 160° C. in air having a relative humidity of less than 50%. The invention further provides a bare spandex-containing knit fabric containing spandex in every knit course that has been exposed to manufacturing process temperature no higher than 160° C. as shown by molecular weight analysis of the spandex and that exhibits wash shrinkage of less than about 14%.

Abstract: Commercial spandex can be prepared with greater efficiency, improved consistency and at lower costs from a high-solids content polyurethaneurea polymer solution. The polyurethaneurea is prepared using a combination of 4,4'-MDI and 2,4'-MDI, and an amount of chain extenders and chain terminators such that the polymer solution, prior to spinning, is highly soluble and has an appropriate pre-spun IV and primary amine content. Such spandex fibers, and the fabrics and garments comprising them, have good dyeability and colorfastness, as well as other desirable characteristics.
