Fiber Fixing Agent for Polyester Nylon and Blends

Fiber Fixing Agent Description

• 22307 is mainly composed of polyamine polymer.
• In the setting process for polyester/ cotton fabrics, it can react with hydroxide radical on cotton fibers and have an auto reaction to crosslink to form a film, which can decrease the influence on fastness by sublimation of disperse dyes and improve the soaping color fastness and steam ironing color fastness.
• It is suitable for polyester/cotton fabrics, which can decrease the influence on fastness after setting.

Fiber Fixing Agent Features

1. Contains no formaldehyde, APEO, or heavy metal ions. Fits environmental protection requirements.
2. Has a certain inhibiting effect on the sublimation of dispersed dyes in the setting process, especially dyes of bright red, black and blue.
3. Do not influence the hand feeling or color shade of fabrics.
4. Reduces one-time middle setting. Shortens process.
5. Easy to use. Can be used together with silicone oil in the same bath in the setting machine.

Fiber Fixing Agent Typical Properties

Fiber Fixing Agent Instruction

Padding process:

• Reference dosage of 22307: 10~40 g/L
• Reference dosage of softener: X g/L
• Dipping and padding (Pickup: 70~100%) → Drying and setting (130~160℃)

Application Example

To improve the fastness of double-sided fabric of 50/50 polyester/cotton:

（1）Dyeing polyester:

• Bright red: Disperse dye of bright red GS: 1.5%, High temperature leveling agent: 1 g/L, Acetic acid: 0.5 g/L
• Turquoise blue: Disperse dye of turquoise blue SGL: 1.5%, High temperature leveling agent: 1 g/L, Acetic acid: 0.5 g/L
• 25℃ → 130℃×40 min (2℃/min) → Water washing

（2）Reduction clearing:

• Sodium hydrosulfite: 3 g/L
• Caustic soda: 2 g/L
• 80℃×15 min (2℃/min) → Water washing

（3）Dyeing cotton:

• Turquoise blue: Reactive dye of turquoise blue BGFN: 1.5%, Reactive dye of brilliant blue KN-R: 1%,
• Anhydrous sodium sulphate: 60 g/L, Caustic soda: 20 g/L
• Bright red: Reactive dye of bright red 3BS: 2%, Reactive dye of yellow 3RS: 1%,
• Anhydrous sodium sulphate: 60 g/L, Caustic soda: 20 g/L
• 25℃ → 60℃×60 min (2℃/min) → Water washing

（4）Soaping:

• Non-foaming soaping agent: 2 g/L
• 95℃×20 min (2℃/ min) → Water washing

（5）Fixing:

• Formaldehyde-free fixing agent: 1%
• 40℃×20 min → Drying

（6）Setting:

• Fixing Agent 22307: 0, 20, 40 g/L
• Dipping and padding → Setting (170℃×about 90s)
