According to DyStar, the product provides wet processing fastness that is higher than that offered by its Mordant Black 9 types and Reactive Black 5 types for wool black; and fiber coverage that is superior to that offered by its CI Reactive Black 5 types and Black PV types. Its shade and metamerism are identical to CI Mordant Black 9 types with good buildup. DyStar reports that Realan Black MF-PV is free of alkylphenol ethoxylate and adsorbable organic halides, and is in full compliance with Oeko-Tex® Standard 100 and the Restricted Substances Lists.

Flexsil brand for permanent silver based anti-bacterial protection

4Ag Flex Technologies, an Indian producer of yarns and fibres, is developing a new range of anti-bacterial products that cover various applications from life saving body armour fabrics to wound care dressings and lifestyle products, using a permanent proprietory metallisation technology. The company is working under the Flexsil brand to provide microbial protection, serving military, healthcare, home textiles, sports and consumer markets. Flexsil brand is not a treatment technology and its metallisation technology entails permanent chemical bonding between the substrate (nylon 66) with silver.

The various atoms of nylon get bonded with silver via a process called coordination bonding. The metalized nylon can be in the form of filament yarn, staple, chopped fibre, fabrics or foam. The silver on the surface of the substrate is said to be of highest purity (99.99%). When silver metal on the substrate comes in contact with bacteria or fungi, positive ions of silver are released. The ions first lyses the cell wall, then goes after the respiratory segment of bacteria and finally binds with DNA thereby completely killing the pathogenic bacteria. The company is also offering Smart Shirts having embroidered antennae using Flexsil multi filament silver yarns. The embroidered antennae can be used by devices worn by the user to transmit and receive radio signals or to boost the device’s own transmission range.
