FAST COOLING

The 50/1 interlock jersey made from 100% cotton with Liquid Ammonia Treatment (LAT) achieves a high QMAX value (cooling sensation) for the following key reasons:

 

1. Fiber structure optimization
The liquid ammonia treatment causes the cotton fibers to swell, reorganizing the cellulose molecules to increase crystallinity and reduce surface roughness. This results in a smoother fiber surface, lowers thermal resistance, and enables faster heat conduction from the skin to the fabric.

 

2. Fabric surface and contact efficiency
The dense and uniform structure of the interlock jersey (195 gsm, fine 50/1 yarn), combined with the defibrillation effect of LAT, creates a flatter and more homogeneous surface. This increases the actual contact area with the skin, accelerating instantaneous heat transfer (the primary factor determining QMAX).

 

3. Synergy between moisture absorption and heat dissipation
The LAT treatment enhances the moisture absorption and transport properties of cotton. When moisture from the skin is absorbed by the fabric, it evaporates quickly; this latent heat loss amplifies the cooling sensation and significantly increases the measured QMAX value (well above the standard 0.15 typical of untreated cotton).

 

NO IRON (Easy Care)
Our 100% cotton interlock fabric with LAT technology (Liquid Ammonia Technology) achieves an industrial-grade no-iron rating of 3.5 (the gold standard for wrinkle resistance) and exceeds expectations by maintaining a 3.5 rating even after 5 washes (well above the minimum requirement of ≥ 3.0).

Made with a premium 195 gsm double-knit 50s/1 structure, the LAT treatment modifies the cotton fibers to ensure long-lasting smoothness, validated by rigorous ISO 7768:2009 / 6330:2012 testing.
Medium and light shades easily achieve a no-iron level of 3.5, while dark colors reach an even higher Grade 4 smoothness—combining the comfort of pure cotton with outstanding wrinkle resistance, even after numerous washes.

 

ANTIBACTERIAL
The process describes a method for creating an antibacterial cotton fabric with durable covalent bonding using UV light irradiation. The sequence involves several specific stages:

• Pre-impregnation: The cotton fabric is soaked in a solution containing both antibacterial agents and photoinitiators.

• UV light exposure: The fabric is exposed to ultraviolet light.

• Initiation: UV light induces the photoinitiators to generate highly reactive free radicals.

• Covalent bonding: These free radicals trigger a chemical reaction in which the antibacterial agents form permanent covalent bonds with the hydroxyl groups present on the cotton fibers.

• Bacteriostasis: The result is a modified fabric with long-lasting (permanent) bacteriostatic properties, meaning it inhibits bacterial growth even after repeated washing.

This method is considered an effective way to functionalize cellulose-based textiles because the bond is chemical rather than physical adsorption, ensuring that the antibacterial properties do not easily wash out.
