20110047718 | Dyeable Polyester Fibers, Methods for Preparing the Same and Applications Thereof - A method for dyeing a modified polyester fiber is provided. A polyester composition is melt blended with a modifying agent to form a thermoplastic composition. The modifying agent is an aliphatic-aromatic co-polyester, and present in an amount of about 1 to 16 parts by weight per 100 parts by weight of the thermoplastic composition. The thermoplastic composition is melt spun to obtain the modified polyester fiber, and the modified polyester fiber is dyed with a disperse dye at a temperature between about 100° C. and about 130° C. | 03-03-2011 |
20120180232 | PRODUCING SPINNABLE AND DYEABLE POLYESTER FIBERS - The present invention relates to a process for producing dyed polyester fibers (C) from a terephthalate polyester (A), at least one polyester-containing additive (B) and optionally at least one component (G). The polyester-containing additive is obtainable by condensation of the monomers of an aliphatic 1,ω-diol, of an aliphatic 1,ω-dicarboxylic acid and of an aromatic 1,ω-dicarboxylic acid. Optionally, chain extenders (V) are also used in the production of the polyester-containing additive (B). For fiber production, the components (A), (B) and optionally (G) are mixed, melted in an extruder and extruded through spinneret dies. These polyester fibers (C) are preferably used in the production of dyed textile fabrics (F). | 07-19-2012 |
20120198634 | Process For Dyeing Carpets With Unused Yarns - Overdyed carpets, as well as other textiles, and methods of producing the same are provided. Overdyeing can be performed on predyed and/or undyed fibers to produce an overdyed carpet with a predominant hue throughout. Predyed fibers can differ in hue, saturation, or value, or any combination thereof from each other and/or from the overdye. The overdyed carpet can include at least one auxiliary chemical. A single auxiliary chemical or a combination of auxiliary chemicals can provide stain resistance, color fastness, and/or bleach resistance, or any combination thereof. These carpets and methods provide aesthetic, financial, and environmental benefits by allowing for utilization of waste fiber, yarn, carpet, and other textiles that would otherwise require resale at substantial discount or landfill disposal. | 08-09-2012 |
20130000057 | PREPARATION OF INDIGO-DYED COTTON DENIM FABRICS AND GARMENTS - Disclosed herein is the preparation of indigo-dyed cotton denim fabrics suitable for use in making cotton denim garments and other denim articles. These indigo-dyed fabrics are prepared from cotton warp yarn which has been pre-treated with an emulsion copolymer prior to being contacted with an aqueous dye liquor comprising a dispersion of an indigo dyestuff. Such copolymer-treated cotton warp yarn can be woven or knitted into cotton denim griege fabrics along with untreated cotton weft yarn. Such griege denim fabric can then be indigo-dyed using the aqueous dye liquor. Alternatively, the emulsion copolymer-treated cotton warp yarn can be indigo-dyed by contact with the aqueous dye liquor before this warp yarn is incorporated into denim fabric along with the untreated cotton weft yarn. The cotton denim fabric produced by either method has the appearance of conventional ring-dyed indigo fabrics. | 01-03-2013 |
20140150187 | PREPARATION OF INDIGO-DYED COTTON DENIM FABRICS AND GARMENTS - Disclosed herein is the preparation of indigo-dyed cotton denim fabrics suitable for use in making cotton denim garments and other denim articles. These indigo-dyed fabrics are prepared from cotton warp yarn which has been pre-treated with an emulsion copolymer prior to being contacted with an aqueous dye liquor comprising a dispersion of an indigo dyestuff.

The cotton denim fabric produced by either method has the appearance of conventional ring-dyed indigo fabrics. | 06-05-2014 |
20150322624 | TREATMENT OF FIBERS FOR IMPROVED DYEABILITY - The present technology is directed to devices and methods for dyeing a fiber, including pretreatment of the fiber before contacting it with a dye. The present technology is also directed to methods of improving the dyeability of a fiber, as well as increasing the efficiency of the dyeing process and minimizing waste and loss of dye. | 11-12-2015 |
