Patent number: 8232335Abstract: Thermoplastic articles may be manufactured having a high degree of visual appeal to consumers. Clarifying agents may be employed as additives in such thermoplastic articles to produce high clarity articles. A coloring agent may be mixed with clarifying agents to form a first blend, and then such a first blend may be applied in very low loadings to form a clarified polymeric article. It is possible to achieve an observable visual benefit while using very low loadings of coloring agent in a polyolefin, such as polypropylene. Carbon black is a pigment that may provide such observable benefits in polypropylene.Type: GrantFiled: February 7, 2006Date of Patent: July 31, 2012Assignee: Milliken & CompanyInventors: Todd D.

Patent number: 8022133Abstract: It is possible to improve significantly the optical performance of diacetal or DBS-based nucleating or clarifying agents using a co-additive. Haze is a measure of the lack of clarity in a thermoplastic or plastic material. A low level of haze is usually quite desirable, and nucleating/clarifying agents are designed to reduce the degree of haze in a plastic or thermoplastic material. A co-additive may be used in connection with a nucleating/clarifying agents in a polymer or copolymer to achieve even greater results in terms of improved clarity (reduced haze), or in terms of a higher crystallization temperature (Tc) of the polymer. A method for reducing haze in polymer articles using a co-additive composition in addition to nucleating and clarifying agents is disclosed.Type: GrantFiled: January 28, 2005Date of Patent: September 20, 2011Assignee: Milliken & CompanyInventors: Jiannong Xu, Jiang Li, Benjamin W.

Patent number: 8012890Abstract: Provided herein are flame resistant fabrics having a thermoplastic fiber content of as much as 65% (where no more than 5% of the fibers are non-thermoplastic synthetic fibers). The flame resistant properties are imparted by treating the fabric with one or more flame retardant chemicals and then by curing the treated fabric at high temperatures. Optionally, softeners, stain release agents, soil repellent agents, permanent press resins, and the like may be added to the bath of flame retardant chemicals. Alternately, the treated fabric may be subjected to mechanical treatment to increase softness. The fabrics produced by the present process exhibit improved performance and tear strength, as compared to conventionally treated fabrics.Type: GrantFiled: October 30, 2008Date of Patent: September 6, 2011Assignee: Milliken & CompanyInventors: Shulong Li, Richard A.

Patent number: 8012891Abstract: A process for imparting flame resistance and the flame resistant fabrics produced by such process are provided. The process for imparting flame resistant properties involves treating a target fabric with one or more flame retardant chemicals (and, preferably, a softening agent) and then curing the treated fabric to durably affix the flame retardant to the fabric. In many cases, it may be desirable to subject the treated fabric to mechanical face finishing to increase softness. Optionally, stain release agents, soil repellent agents, permanent press resins, and the like may be added to the bath of flame retardant chemicals, eliminating the need for one or more additional manufacturing processes. Alternately, soil repellent agents may be applied to only one side of the treated fabric after the application of the flame retardant chemicals. The present fabrics exhibit improved performance and tear strength, even after repeated launderings, as compared to conventionally treated fabrics.Type: GrantFiled: April 30, 2010Date of Patent: September 6, 2011Assignee: Milliken & CompanyInventors: Shulong Li, Richard A. Mayernik

Patent number: 7858539Abstract: Provided herein are processes for topically applying an antimicrobial finish to a textile substrate, such as a yarn, a fabric, a composite, or an assembled article (for example, a garment). Specifically, the antimicrobial finish is based on hindered amine compounds that are applied in an aqueous bath (such as a commercial or home laundry setting), using the factors of pH and compound solubility to promote the formation of a durable antimicrobial halamine finish. Advantageously, the antimicrobial finish, which may be applied to fabrics made of any of a variety of fiber types and combinations of fiber types, has been found to be durable to repeated launderings.Type: GrantFiled: April 9, 2007Date of Patent: December 28, 2010Assignee: Milliken & CompanyInventors: Ling Li, Shulong Li, Jeffrey S.

Patent number: 7781511Abstract: Diacetals of sorbitols and xylitols are employed in polyolefins as nucleating agents. Diacetals of sorbitols and xylitol nucleating agents may be provided in granular or powder form from hoppers or mixing equipment into polyolefins during the formation of polymeric compositions and polymeric articles. Flow of diacetals of sorbitols and xylitols is improved by the use of certain silicas, in certain defined weight percentages. Submicron size range silica compounds may provide excellent flow enhancement properties when blended and used with diacetals of sorbitols and xylitols powder compounds. A hydrophobic silica mixed with diacetals of sorbitols and xylitols compounds also may provide enhanced flow properties for such mixture, as compared to mixtures using hydrophilic silica. Loading ranges of silica may be important in improving the flow of diacetals of sorbitols and xylitols compounds.Type: GrantFiled: September 12, 2005Date of Patent: August 24, 2010Assignee: Milliken & CompanyInventors: Jiang Li, Jiannong Xu, Michael J.
