Patent number: 6878767Abstract: A paint which contains a multitude of extremely thin platelets having a large area/thickness ratio, which serve to greatly reduce permeability of the paint when applied and dried. The formulation comprising at least a filmogen, a pigment, and a multitude of chemically-treated platelets about one nanometer thick. The platelets being dispersed in the formulation so that after application and solidification of a coating of the paint the platelets form a barrier substantially impermeable to both liquids and gases.Type: GrantFiled: October 25, 2001Date of Patent: April 12, 2005Assignee: Shenkar College of Textile Technology & FashionInventor: Shmuel Kenig

Patent number: 6105622Abstract: The present invention relates to a method for weaving a three dimensional structure by providing a set of planar warp yarns arranged in a plurality of planes, where each plane contains yarns arranged in a decreasing spacing from top to bottom. The plurality of planes are also positioned in a perpendicular direction so that the spacing between adjacent planes decrease from top to bottom, and a weft yarn is inserted between the adjacent planes at a point where the spacing is largest. A moving rod and shaped reed are used to pull and beat the weft yarns into the three dimensional structure situated at a base of the planar warp yarns, where the shaped reed has reed wires arranged in decreasing spacing from top to bottom.Type: GrantFiled: March 2, 1998Date of Patent: August 22, 2000Assignee: Shenkar College of Textile, Technology and FashionInventors: Alon Sternheim, Percy Grosberg

Patent number: 5504975Abstract: A method and apparatus for combing wool in which the wool is heated prior to being fed to the combing process. The wool is heated by heat rollers or other means to a temperature such that it becomes more plasticized and better lubricated due to the liquification of the natural fat of wool which then acts better as a lubricant. As a result of this process, there is a reduction in the amount of noil produced. The invention is also applicable to various other animal-based natural fibers.Type: GrantFiled: April 6, 1996Date of Patent: April 9, 1996Assignee: Shenkar College of Textile Technology & FashionInventors: Herzel Bar, Amotz Weinberg

Patent number: 5449025Abstract: Methods for weaving three-dimensional fabric structures which have a desired cross-sectional shape and devices for such weaving in each of two mutually perpendicular directions allow sheds to be formed in planar warps. The sheds enable the insertion of parallel weft yarns through rows of warp yarns. High density three-dimensional fabrics which may be used in the manufacture of advanced composite materials can be woven.Type: GrantFiled: September 16, 1993Date of Patent: September 12, 1995Assignee: Shenkar College of Textile Technology & FashionInventor: Amotz Weinberg

Patent number: 4989297Abstract: The invention relates to a process for rendering harmless sticky material adhering to cotton fibers, termed "honeydew". According to the process the cotton is heated for a brief period of time to a temperature adequate to render said honeydew hard and brittle, and this without adversely affecting the cotton fibers. There are also provided means for effecting such treatment of cotton fibers in a continuous manner.Type: GrantFiled: June 15, 1988Date of Patent: February 5, 1991Assignee: Shenkar College of Textile Technology and FashionInventors: Herzel B. Yecheskel, Gan Alon, Eliezer Beck
