PureFresh™ AM34-Bio
Protect the textile.
Preserve freshness.
A chitosan-based textile technology combining antimicrobial performance and odor adsorption to help treated fabrics stay fresh between washes.
100%
Bio-based content
50
Home washes of durability
2 functions
Antimicrobial + odor adsorption
TWO ROUTES TO FRESHNESS
Antimicrobial performance.
Direct odor control.
Address microorganisms on the textile and odor compounds already present with one bio-based finishing technology.
01
Antimicrobial protection
Helps inhibit bacteria, yeast, and fungi on treated textiles.
02
Odor adsorption
Captures existing odor compounds, including ammonia, alongside antimicrobial activity.
03
Non-leaching design
The active is retained within a fiber-bound biopolymer matrix, supporting non-leaching performance.
04
Durable performance
Designed for functional performance through 50 home washes, subject to the substrate and application conditions.
Assess antimicrobial activity with ASTM E2149 and odor adsorption with a method suited to the target odorant. Compare treated and untreated fabrics before and after laundering.
CHITOSAN. ENGINEERED FOR TEXTILES.
Two mechanisms.
One textile treatment.
AM34-Bio stabilizes chitosan within a biopolymer matrix that bonds to textile fibers. This combines antimicrobial activity with direct capture of odor compounds.
01 Bind
The biopolymer matrix fixes the active to the textile, supporting uniform treatment and non-leaching performance.
02 Inhibit
Positively charged amino groups in chitosan interact with negatively charged components of microbial membranes, disrupting their integrity and inhibiting growth.
03 Adsorb
The matrix also captures existing odor compounds, including ammonia, addressing odors that antimicrobial activity alone may leave behind.
DESIGNED FOR YOUR PROCESS
Performance that fits production.
Evaluate AM34-Bio through padding, exhaust, or spray application. Match the treatment to your substrate, equipment, and performance requirements.
Apply AM34-Bio in a finishing bath with controlled wet pickup. Confirm uniform add-on, fixation, and performance on the intended fabric.
Evaluate substrate compatibility and treatment uptake in the proposed exhaust process. Confirm uniformity and the required finishing conditions through trials.
Use controlled spray application to distribute the treatment uniformly. Verify coverage, add-on, curing, and performance after laundering.
Confirm dosage, bath compatibility, add-on, curing, and wash durability through fabric trials. The technical presentation lists a curing profile of 150°C for 45 seconds; confirm the appropriate conditions with AGS before production.
BIO-BASED BY DESIGN
Bio-based chemistry.
Bound to the textile.
AM34-Bio uses chitosan as its active ingredient within a bio-based formulation. Its fiber-bound matrix is designed to retain the active within the treated textile.
100% bio-based
The AGS technical presentation identifies PureFresh AM34-Bio as a 100% bio-based technology.
Non-leaching design
The active remains stabilized within the polymer matrix rather than relying on release from the textile.
The formulation is ready to use without an additional binding agent, as described in the technical presentation. Confirm process compatibility and finished-fabric performance through trials.
A CLOSER LOOK
Your questions, answered.
What does PureFresh™ AM34-Bio provide?
AM34-Bio combines antimicrobial activity with direct odor adsorption. Chitosan is stabilized within a biopolymer matrix that bonds to textile fibers.
How do the two mechanisms differ?
Antimicrobial activity inhibits microorganisms on the treated textile. Odor adsorption captures existing compounds, including ammonia, that can remain even when microbial growth is controlled.
What does non-leaching mean here?
The active is retained within the polymer matrix on the treated textile. The treatment is designed to function without releasing the active as its mechanism of action.
How durable is the performance?
The AGS technical presentation specifies 50 home washes. Validate the antimicrobial and odor-control performance on your substrate under the intended application and laundering conditions.
How should performance be verified?
Assess antimicrobial performance using ASTM E2149 and select an odor adsorption test suited to the target odorant. Compare treated fabric with an untreated control and repeat testing after laundering.
