Weak Acid/Alkali Resistant Nonwoven

weak acid alkali resistant nonwoven

This fabric is engineered using acrylic fiber as the base material, chemically modified in a reactor vessel to create weakly acidic/alkaline fibers. It provides multifunctional benefits including deodorization, odor elimination, formaldehyde removal, and antiviral effects, serving as a durable, highly efficient, and safe antimicrobial and antiviral textile. Resistant to repeated washing with common household detergents, ensuring durability and performance retention even after multiple laundering cycles.







Advantages of Huiming Weak Acid/Alkali Resistant Nonwoven

  • Weakly Alkaline Fiber:

Appearing yellow in color, this fiber is loaded with carboxyl groups and can serve as a replacement for conventional weakly acidic ion-exchange resins. It features a large specific surface area, rapid ion-exchange kinetics, and strong anti-fouling resistance, making it ideal for applications requiring high efficiency and durability.

  • Weakly Acidic Fiber:

Exhibiting a red hue, this fiber is functionalized with primary, secondary, and tertiary amine groups, acting as a substitute for traditional weakly alkaline ion-exchange resins. It shares key advantages including high specific surface area, fast exchange rates, and robust anti-contamination performance, ensuring reliability in demanding environments.


Weak Acid/Alkali Resistant Nonwoven can be applied to the following fields

  • High-Purity Chemical Production

Utilizes the adsorption and separation capabilities of ion-exchange fibers to remove impurities from chemicals, refining low-purity feedstocks into high-purity products.

  • Air Purification in Specialized Environments

It exhibits high-efficiency adsorption capacity for acidic or alkaline gases in the air under anhydrous or humid environments, and also has high-efficiency adsorption capacity for charged dust particles.

  • Antimicrobial & Antiviral Filtration

Widely applied in healthcare and hygiene industries, ion-exchange materials exhibit:

Antimicrobial & antiviral properties: Inhibit bacterial/viral proliferation in air or liquids.

Odor adsorption: Neutralizes malodorous compounds.

Versatile formats: Engineered as fibers, nonwoven fabrics, or knitted textiles for diverse applications.

  • Purification of Organic Acids (e.g., Citric Acid, Lactic Acid)

By leveraging the excellent osmotic pressure stability of ion exchange fibers, it can meet the requirements of organic acids for ionic form conversion, dry-wet and swelling-shrinkage cycles, as well as the mechanical and chemical stability of materials.

  • Hydrometallurgy

It has a special adsorption and separation effect on metal ions in solutions. Additionally, due to the superior anti-pollution capability of ion exchange fibers compared to ion exchange resins, it has broad prospects in extracting precious metals from solutions.

  • Water Treatment  

In the treatment of water discharge in the environmental protection industry, it plays a role in ion adsorption and separation.
