The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.||05-05-2016|
|20160060074||PROCESS FOR DRAFT CONTROL ON FEEDING OF ELASTIC YARN - A method for unwinding yarn is provided that allows for maximizing the draft of the yarn, while monitoring tension. The method includes providing a yarn package including elastic yarn; choosing a selected draft for said elastic yarn; unwinding the elastic yarn from the yarn package from a driven roll to yarn processing equipment at the selected draft which is determined by a ratio of a speed of the yarn at the yarn processing equipment to a speed of the driven roll; measuring tension in the elastic yarn; and providing an alarm when said tension reaches a critical level.||03-03-2016|
|20130243984||POLYESTER POLYMERIZATION PROCESS - The present invention relates to a process for producing PET based on titanium catalyst having acceptable properties for resin used in the production of bottles for beverages. More particularly the invention relates to a process in which the incoming pre-polymer temperature is higher than the final outlet temperature in the final melt phase polycondensation reactor.||09-19-2013|
|20110311757||SOIL REPELLENCY AQUEOUS DISPERSIONS, SOIL REPELLANT SOFT ARTICLES, AND METHODS OF MAKING THE SAME - A soil repellency aqueous dispersion for treating various fibers, yarns, and textiles is disclosed. The dispersion provides superior soil resistance when compared to known fluorochemical and silicone fiber treatments. The dispersion comprises clay nanoparticle components and fluorochemicals that can be applied to the fibers, yarns, and textiles using known methods.||12-22-2011|
|20110073558||CARBON BLACK WITH LARGE PRIMARY PARTICLE SIZE AS REHEAT ADDITIVE FOR POLYESTER AND POLYPROPYLENE RESINS - Reheat characteristics of polyethylene and polypropylene resins, including reheating time and resin color, are improved by adding to the resin carbon black with a primary particle size in the range of 200 to 500 nm as an infrared absorber. Thermal carbon blacks having this primary particle size are preferred over Furnace carbon blacks. Injection stretch-blow molded bottles and other thermoformed products are made from resins with carbon black infrared absorber.||03-31-2011|

|20100209641||METHOD TO MAKE SINGLE-LAYER PET BOTTLES WITH HIGH BARRIER AND IMPROVED CLARITY - The present invention comprises a blend of polyester and a partially aromatic polyamide with an ionic compatibilizer and a cobalt salt. This blend can be processed into a container that has both active and passive oxygen barrier and carbon dioxide barrier properties at an improved color and clarity than containers known in the art. The partially aromatic polyamide is preferably meta-xylylene adipamide. The ionic compatibilizer is preferably 5-sodiumsulfoisophthalic acid or 5-zinesulfoisophthalic acid, or their dialkyl esters such as the dimethyl ester (SIM) and glycol ester (SIPEG). The cobalt salt is selected form the class of cobalt acetate, cobalt carbonate, cobalt chloride, cobalt hydroxide, cobalt naphthenate, cobalt oleate, cobalt linoleate, cobalt octoate, cobalt stearate, cobalt nitrate, cobalt phosphate, cobalt sulfate, cobalt (ethylene glycolate), or mixtures of two or more of these. The partially aromatic polyamide is present in a range from about 1 to about 10 wt. % of said composition. The ionic compatibilizer is present in a range from about 0.1 to about 2.0 mol-% of said composition. The cobalt salt is present in a range from about 20 to about 500 ppm of said composition.||08-19-2010|
