  • Patent number: 11963309
    Abstract: Processes for laminating a conductive-lubricant coated Printed Circuit Board (PCB) are disclosed. An example laminated PCB may include a lamination stack that may further include a core, an adhesive layer, and at least one graphene-metal structure or at least one hexagonal Boron Nitride metal (h-BN-metal) structure. The materials of the PCB may change in accordance with the invention described herein, including the materials of the core, the materials of the conductive-lubricant coatings, or the metal layers of the conductive-lubricant-metal structures. Doping processes for each change in materials used are also described herein. The conductive-lubricant of the conductive-lubricant-metal structure will promote high frequency performance and heat management within the PCB. Furthermore, a removal process of those materials post-lamination is described herein to promote protection of materials and subsequent removal of protective layers without breakage or tearing.

  • Patent number: 7597722
    Abstract: Process for manufacturing a fabric having distinctive and sharp differentially colored patterns or designs, which process comprises the steps of: (a) producing a first and a second polyamide, said polyamides having different concentrations of amine groups; (b) producing a first and a second polyamides having different concentrations of carboxyl end-groups and sulfonate groups; (c) producing a first yarn from said first polyamide and a second yarn from said second polyamide; (d) making a fabric having first surface areas defined by said first yarn and second surface areas defined by said second yarn; and (e) chemically dyeing said fabric in a dyeing bath comprising at least one anionic (acid) dyestuff and at least one cationic (basic) dyestuff, whereby said first yarn and therefore said first surface areas are dyed predominantly by said anionic dyestuff and said second yarn and therefore said second surface areas are dyed predominantly by said cationic dyestuff.

  • Patent number: 6524503
    Abstract: A process for the manufacturing of a differentially dyeable yarn includes the steps of: a) producing two polymers having a different concentration of amine end-groups; b) spinning yarns from said two polymers; and c) producing a yarn by intermingling said spun yarns made from said two polymers, in texturing, or draw twisting, or draw winding processes.
