As a result of our chemical application experience, Unichem is the sales representative for Gaston Systems, Inc.  Gaston Systems manufactures patented equipment for accurately applying water soluble or dispersible chemicals at very low moisture levels onto or into substrates such as fabrics, carpet, non-wovens, paper and other flexible materials.  Unichem and Gaston systems can provide you with a total solution-equipment, controls, and chemical formulation to meet your needs.  Together, Unichem and Gaston Systems are the world leader in chemical foam technology.  

Unique Features of CFS

  • The foam generator achieves blow ratios of over 100:1 through a unique foamer head design.

  • The parabolic applicator assures uniform application across the substrate width.

  • The control system provides precision application and repeatability independent of line speed.

CFS achieves precise, uniform application of chemicals to open-width substrates at wet pick-up levels as low as 5% and at speeds beyond 3,000 feet per minute.  Applying chemicals through a foam medium produces many benefits over traditional application methods.

  • Significant chemical savings without sacrificing performance.

  • Energy savings up to 60% due to less water to evaporate; pre-drying eliminated.

  • Increased line speeds.

  • Improved material aesthetics through more uniform chemical distribution, negligible migration, and elimination of after-treatment for softer hand.

  • Controlled chemical penetration into substrate.

  • Chemicals can be applied on back and face simultaneously.

  • Often produces improved seam strength at reduced latex add-on rates.

This photo of a nonwoven substrate, with pigment and finish applied to each side demonstrates the precision application of CFS.


CFS has been used for coating, finishing, pigmenting, and moisturizing a wide variety of substrates. Its unique ability to precisely control add-ons and penetrations allow replacement of pads, vacuum systems, sprays, kiss rolls, print screens, knife coaters, and other wet finishing techniques. A few examples of its flexibility are shown here:


  1. Latex application to nonwoven

  2. Latex treatment to back of  upholstery material

  3. Latex coating on drapery fabric

  4. Deep, one-sided penetration of binder into trunk liner material, providing a moldable product with a soft outer surface

  5. Binder applied completely through filler material

  6. One-sided resin finishing of apparel fabric

  7. Yarn treatment in slashing application

  8. Wetting agent applied to diaper material

  9. Pigment and finish applied to each side of nonwoven with very slight penetration
