  • Process for protecting dyed nylon fibers from colorants and chemical agents
    Patent number: 6814758
    Abstract: Nylon fibers are protected from colorant staining by treating them with at least 2% we/wt (weight dry SAC/weight dry nylon fiber) of sulfonated aromatic aldehyde condensation product. The treated fibers are then fixed by the wet heat method.
    Type: Grant
    Filed: April 22, 2002
    Date of Patent: November 9, 2004
    Assignee: Simco Holding Corporation
    Inventors: Joseph A. Pacifici, Daniel G. Sims
  • Nylon fiber protective finishing compositions and methods of manufacturing same
    Patent number: 6616856
    Abstract: A protective finishing composition for protecting nylon fibers comprises an aqueous mixture of a sulfonated aromatic aldehyde condensation stainblocker, a methacrylate stainblocker, a fluorocarbon-based repellant emulsion, and a naphthalene sulfonated salt fluorocarbon anti-coalescing agent in an amount effective to prevent said fluorocarbon based repellant emulsion from coalescing in the presence of the stainblockers.
    Type: Grant
    Filed: February 6, 2002
    Date of Patent: September 9, 2003
    Assignee: Simco Products, Inc.
    Inventors: Joseph A. Pacifici, Daniel G. Sims
  • Method of removing colorants from wastewater
    Patent number: 6059978
    Abstract: Cationic polymers are added to wastewater containing colorants to form a cationic polymer/colorant complex. Anionic polymers are then added to the wastewater to produce a flocculent precipitate that is separated from the wastewater.
    Type: Grant
    Filed: May 6, 1998
    Date of Patent: May 9, 2000
    Assignee: Simco Holding Corporation
    Inventors: Joseph A. Pacifici, Daniel G. Sims
  • Method for dyeing nylon fabrics in multiple colors
    Patent number: 5925149
    Abstract: When nylon fibers are dyed with a first anionic dye and then treated with a stainblocker, they can be woven into a fabric with untreated nylon fibers and then subjected to a second dyeing process using a second anionic dye of a different color than the color of the first anionic dye, without risk of dye bleed or dye blending during the second dyeing operation.
    Type: Grant
    Filed: February 17, 1998
    Date of Patent: July 20, 1999
    Assignee: Simco Holding Corporation
    Inventors: Joseph A. Pacifici, Daniel G. Sims
  • Nylon fiber protective finishing compositions and methods of manufacturing same
    Patent number: 5843328
    Abstract: Protective finishing compositions and methods of manufacturing such compositions for finishing carpet products with a stainblocker and fluorocarbon-based repellant in a one-step process, include first adding a naphthalene sulfonated salt to either a stainblocker or a fluorocarbon-based repellant and then adding the combination to the chemical not originally mixed with the naphthalene sulfonated salt.
    Type: Grant

  • Method of treating acid dyed nylon fibers to enhance colorfastness
    Patent number: 5417724
    Abstract: The cold water bleed propensity of acid and premetallized acid dyed cationic dyeable nylon fibers is substantially reduced by treating the fibers with both a nylon fixing agent and a cotton fixing agent. Colorfastness of acid and premetallized acid dyed nylon fibers, other than CD nylon fibers, is also enhanced by treating the fibers with both a cotton fixing agent and a nylon fixing agent.

    Inventors: Joseph A. Pacifici, Daniel G. Sims
  • Method of treating cationic dyeable nylon fibers to inhibit cold water bleed
    Patent number: 5342417
    Abstract: A method for reducing the cold water bleed propensity of acid and premetallized acid dyed cationic dyeable nylon fibers which comprises treating such fibers with sulfonated anionic polymers, useful as nylon fixing agents, and cationic amine based polymers, useful as cotton fixing agents.
    Type: Grant
