The effectiveness of a textile softener is not solely determined by its chemical composition, but also by how it is applied. For hydrophilic cationic softener flakes, understanding the optimal processes ensures maximum benefit to the fabric. NINGBO INNO PHARMCHEM CO.,LTD. offers guidance on integrating these advanced textile auxiliaries into finishing workflows.

Two primary methods are commonly used for applying softener flakes: the padding process and the dipping process. Each method has its advantages and is suited to different production scales and fabric types.

Padding Process:

In the padding process, fabrics are passed through a trough containing a diluted working solution of the softener. The fabric then goes through squeeze rollers to remove excess liquor, ensuring a consistent application. For our Hydrophilic Cationic Softener Flake, a typical recommendation might involve a concentration of 30-50 g/L of a 10% diluted solution. The padding is usually carried out at a moderate temperature (30-40°C) with a rolling over rate of 70-90%. This method is efficient for continuous processing and large volumes of fabric.

Dipping Process:

The dipping process, often used for batch treatments or more delicate fabrics, involves immersing the fabric in a liquor bath. For the cationic softener flakes, a dosage of 3-8% (on weight of fabric, o.w.f.) of a 10% diluted solution is generally recommended. The bath ratio, typically 1:10 to 1:15, is important for ensuring adequate dilution and uniform treatment. The process is carried out at temperatures between 20-30°C for 15-30 minutes, followed by dehydration and drying. This method allows for precise control over the treatment duration and concentration.

Dilution Method:

Preparing the working solution from flakes is a critical first step. A warm dilution method is often preferred: pour the flakes slowly into room temperature water at a proportion of 5-10%, stirring for 3-5 minutes. Gradually heating the mixture to 65-75°C while continuing to stir ensures complete dissolution, forming a uniform paste. It's important to stir until the flakes are completely dissolved to prevent clumping and ensure a homogenous solution for application.

NINGBO INNO PHARMCHEM CO.,LTD. advises that proper dilution and adherence to recommended application parameters are key to unlocking the full potential of their hydrophilic cationic softener flakes. These processes help achieve the desired softness, hydrophilicity, and color fastness, ultimately enhancing the value of the finished textiles. Manufacturers are encouraged to consult specific product datasheets for precise instructions tailored to their unique production environments.
