AngelThread®

Core technology

Silver at the atomic scale, antimicrobial inside the fiber.

AngelThread® developed semiconductor-grade vacuum vapor deposition in Taiwan. A fab-floor physical process, brought into textile yarn — no chemistry, no coatings, no finishing.

Three scales, three fates

Why scale matters.

From bulk to nano to atomic, every order of magnitude smaller is an order of magnitude stronger — but "will it wash out" is what really decides.

Process

A physical process from the fab floor.

Traditional antimicrobial textiles depend on dyeing, coating or finishing. AngelThread® puts silver inside — not on top.

  1. 01

    Vacuum sputtering

    In a high-vacuum chamber, silver atoms are sputtered onto a polymer film — physical deposition, zero chemical solvents.

  2. 02

    Masterbatch

    Silver-bearing film is converted into PET masterbatch pellets with silver atoms uniformly distributed.

  3. 03

    Spinning extrusion

    Pellets are extruded into continuous filament. Silver is locked inside the PET structure, never on the surface.

  4. 04

    Weaving

    100% antimicrobial polyester yarn, or blended with cotton / nylon / elastane for brand customers.

How it works

Why Ag⁺ kills microbes.

AngelThread®'s silver is embedded atoms, not an added biocide. In contact with sweat and ambient moisture, trace Ag⁺ releases slowly. Three mechanisms — all well-documented in literature.

  1. 01

    Disrupts cell membrane

    Ag⁺ binds to negatively-charged membrane components, damaging structure and protective barrier.

  2. 02

    Inhibits enzymes

    Ag⁺ inactivates intracellular metabolic enzymes, blocking energy pathways. Cells can't sustain function.

  3. 03

    Blocks DNA replication

    Ag⁺ binds bacterial DNA, interfering with replication and division — reducing colony size at the base.

A side effect of doing silver right

AngelThread® atomic-silver antimicrobial technology replaces chemical biocide dyeing

83% average reduction.

Traditional antimicrobial finishing depends on silver chloride dipping, drying and post-treatment — water-heavy, energy-heavy, chemical-heavy, wastewater-heavy. Physical deposition swaps chemistry for physics. Internal LCA on 10,000-yard production:

-85%
Water use
-78%
Energy
-92%
Chemicals
-71%
CO₂ emissions
-89%
COD wastewater

Baseline: same yardage and fabric type with traditional silver chloride dyeing. ISO 14067 (carbon) and ISO 14046 (water) third-party verification in progress.
