Nestogen - AST | Hydrophilic Soil Release / Antistatic Agent

• Product Information

  Nestogen - AST Application on Polyester:

  When applied to polyester, Nestogen - AST creates a robust polymer film that readily interacts with water, resulting in a hydrophilic finish. This polymer has the ability to absorb moisture from the atmosphere, preventing the accumulation of static charges on the polyester. The durable treatment imparts the following notable properties:

  1. Inhibition of Static Charge Formation:

     • Prevents the build-up of static charges on polyester.

  2. Drastic Enhancement of Wearer Comfort:

     • Significantly improves the overall comfort experienced by the wearer.

  3. Improvement in Polyester Wetting Action:

     • Enhances the moisture absorption capability of polyester.

  4. Soil Release Effect:

     • Facilitates easy cleaning of polyester by releasing oil-based stains and soils.
     • Prevents the deposition of stains, making polyester extremely easy to clean and maintain.

   

• Key Features & Benefits

   

  Nestogen - AST when applied on polyester forms a durable polymer film that interacts readily with water imparting a hydrophilic finish. This polymer absorbs moisture from the atmosphere that does not allow static charges to build up on the polyester. This durable treatment imparts the following properties:

  • Inhibits formation of Static charge
  • Enhances wearer comfort drastically
  • Improves wetting action of polyester
  • SOIL RELEASE effect: This Makes polyester extremely easy to clean by releasing oil based stains and soils and preventing deposition of stains.

• Application

  • A. By Exhaust (Yarn, Fabric & Garment)
  • Set bath at 40 °C & pH: 5 - 6 with acetic acid.
  • Add Nestogen - AST: 3-4% owf.
  • Raise temperature to 60-80° C & run for 20-30 minutes.
  • Dry the yarn/fabric/garment below 150° C.
  • B. HPHT Dyeing (Yarn & Fabric)
  • The preferred method of applying the product is during high-temperature dyeing with virtually no change in normal dyeing procedure.
  • Set bath at 40° C & pH: 5-6 with acetic acid.
  • Add Nestogen - AST: 3-4% owf.
  • Raise temperature to 60–65 °C.
  • Add disperse dye stuff before reaching 80 °C.
  • Keep the temperature at 80° C for 10-15 min for good exhaustion.
  • Continue with the usual dyeing process.
  • When dyeing heavy shades, raise temperature to 60° C and hold for 45 minutes, add dyestuffs, and continue with the usual dyeing process.
  • Application Notes:
  • Avoid drying temperature above 176 °C.
  • Avoid bath pH >8.0.
  • Avoid adding Nestogen - AST Copolymer after electrolytes or resins are in the mixing tank.

   

   

• Advantage

  Nestogen - AST Copolymer is a durable textile finish softener for polyester yarns and fabrics. It imparts soil-release, lubricity, antistatic properties and increased moisture absorbency to polyester fabrics.

  It is particularly effective on knit fabrics made from polyester yarns.
