Wetting Agents are specialty chemicals in the Surface Active Agents group, typically known as surfactants. Their primary function is to aid in the dyeing process of fabrics. They have been in vogue in the textile industry since their inception in science laboratories, primarily to facilitate optimum dye particle incorporation into the fabrics. Powerful wetting agents boast high water absorbency and premium alkaline stability, which are indispensable for the best colour dispersion.
In this blog, we analyse the potential of Primasol NF as an effective wetting agent, focusing on the parameters that set it apart and lend a radical twist to its auxiliary properties.
Significance of Wetting Agents
Cellulosic fibres like Cotton, Jute, Flax, Rayon, and Hemp need thorough pre-treatment with appropriate auxiliaries to enhance their porosity for even and long-lasting colouration. Soaking such fabrics in a wetting agent enlarges the fabric pores, heightening the penetrability of the chemical dye. Wetting Agents are a distinctive batch of textile auxiliaries used to treat fabrics to elevate their absorbing capacity before applying the dyeing chemical. These chemicals enhance and accelerate the colouring of fabrics by reducing the cohesion between water molecules and making the fabric material more pliant towards absorbing the dye.
Working Principle of Wetting Agents Specialty Chemicals
Raw yarns need to be processed appropriately to enable them to absorb water. Soaking textiles in wetting agents facilitates maximum dye penetration, which warrants a desirable colour outcome. The textile to be treated acts as the substrate, while the dye and wetting agent solutions act as the two immiscible reacting phases with water as the medium. The wetting agent auxiliaries are formulated so that the potent cationic or anionic components minimise the distance between the two by lowering the high surface tension, allowing uniform colouration of the fabric. The lowest possible surface tension achieved, called Critical Micellar Concentration or CMC, opens the ionic gates, making the colouring particles fit for penetrating the fabric materials.
Primasol NF: Potency as a Wetting Agent
Primasol NF is a high-performance new-age anionic wetting agent responsible for textile fabrics’ vibrant and long-lasting colours. It is low-foaming and ensures uniform colouration while arresting colour bleeding. Due to its powerful intermolecular force, hard water has always been an inhibitor in textile dyeing. Vigorous cohesive bond between the molecules accounts for the impeccable surface tension of hard water. Similar specialty textile chemicals contain one hydrophilic head and a hydrophobic tail. In the aqueous solution of the de-aeration chamber, the hydrophilic end goes in between water molecules, lowering their cohesive forces as well as the surface tension of the entire aqueous phase, leaving the fabric pores open to allow the dye material to settle at a prime concentration.
Gaining leverage in the modern textile industry
The textile industry is based on several verticals, from raw material production, spinning yarn, weaving/knitting, fabric dyeing/printing, and finishing to final garment manufacturing. A lot of synchronisation goes into ensuring optimal colour settlement into the fabric. The primary reagent of Primasol NF, known as Sodium Dodecyl Sulphate (SDS), is hailed as a force due to its prompt action on textile fabrics, low-foaming and vapour scavenging properties, smooth finish, its ability to impart long-lasting colour and increased durability of textiles. Primasol NF has proven to be biodegradable, affordable and non-hazardous. More and more companies are embracing it as a magic component to pre-treat their fabrics. It stimulates productivity, ensures bulk output, and provides longer life to the garments.
