Publication number: 20120135653Abstract: Disclosed is an artificial leather containing a non-woven fabric composed of ultra micro fibers and impregnated with an polymeric elastomer, wherein a residual shrinkage ratio of the artificial leather at 30% stretching is 10% or less in a machine direction and is 20% or less in a cross-machine direction. The artificial leather has optimal residual shrinkage ratios, and specifically a residual shrinkage ratio in a machine direction of 10% or less and a residual shrinkage ratio in a cross-machine direction of 20% or less, when the artificial leather is stretched by 30%. As a result, the artificial leather which has stretched during the process for shape-formation can easily contract and restore, and thus avoid creasing even when applied to the products having many curved parts.Type: ApplicationFiled: June 3, 2010Publication date: May 31, 2012Applicant: KOLON INDUSTRIES, INC.Inventors: Yeong Nam Hwang, Won Jun Kim, Jong Ho Park

Patent number: 6649689Abstract: This invention relates to hydrophilic curable alkoxylated silicone polymers for surface modification and are useful in, e.g., fiber and fabric care, hair care, skin care, surface care, and car care compositions. The compounds are curable silicone polymers which contain one or more polyalkyleneoxy groups, preferably polyalkyleneoxy pendant groups, comprising at least some ethyleneoxy units, said polyalkyleneoxy pendant groups are preferably capped with low molecular weight alkyl groups, such as C1-C6 alkyl groups. These compounds are substantive to the surface but keep the surface hydrophilic.Type: GrantFiled: November 15, 2001Date of Patent: November 18, 2003Assignee: The Procter & Gamble CompanyInventors: Eugene Paul Gosselink, Toan Trinh, Robb Richard Gardner

Publication number: 20030134118Abstract: Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. Such fibers (and thus the initial films and/or tubes) require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling.Type: ApplicationFiled: December 21, 2001Publication date: July 17, 2003Inventors: Brian G. Morin, Martin E. Cowan, Kenneth B. Higgins
