  • Hardware specifications
  • Physical & Chemical Properties

    Appearance: Tan liquid

    Ionic Type: Anionic / Non‑ionic

    pH Value (1% aqueous solution): 7.0‑9.0

    Solubility: Dilutable with water at any ratio, disperses uniformly in aqueous solutions

     

    Features & Advantages

    It has strong affinity toward polyamide fibers. The agent bonds with fiber substrates and occupies dye sites at the initial dyeing stage, triggering competitive dye uptake against dyes to deliver retarding and leveling outcomes.

    Powerful migratory capacity boosts dye migration under high‑temperature processing, effectively eliminating fabric defects such as barré and mottled uneven dyeing.

    Elevates dye penetration to secure consistent, premium dyeing performance.

    Low‑foam formulation.

     

    Application Instructions

    Standard recommended dosages:

    Acid Leveling Agent YH‑2203: 0.5‑2.0% o.w.f; higher dosage is required for paler fabric shades

    Temperature & holding duration: 95‑120℃ with 30–60 minutes of holding time

    Dosage for re‑dyeing repair jobs: 2‑4% o.w.f

    Note: Conduct production trials matching your on‑site process conditions to finalize optimal dosage and processing parameters.

     

    Storage & Packaging

    Sealed goods retain a 6‑month shelf life inside dry, cool and ventilated warehouse storage. Standard packaging specifications are 50 kg and 125 kg plastic drums.
