Achieving excellent fabric fastness is a critical objective for any textile manufacturer. Fastness properties, such as resistance to washing, rubbing, and perspiration, directly impact the perceived quality and durability of a textile product. NINGBO INNO PHARMCHEM CO.,LTD. provides advanced formaldehyde-free fixing agents that are instrumental in enhancing these properties, particularly for fabrics dyed with reactive and direct dyes. This guide outlines the principles and practices for effectively utilizing these textile chemicals and auxiliaries.

The efficacy of our formaldehyde-free fixing agents lies in their cationic nature and advanced polymer chemistry. These agents form a protective complex with dye molecules, significantly improving their adherence to the textile fibers. For optimal results, it is crucial to follow recommended application processes. Typically, the fabric should be thoroughly washed and soaped after dyeing to remove unfixed dye. Following this, the fixing agent is applied in a fresh bath. The recommended dosage often varies based on the depth of the color and the specific dyeing process used, but common application rates for impregnation or exhaust processes range from 0.15% to 0.4% (O.W.F.) or 1.5-5 g/L for padding processes.

Key considerations during the application include maintaining the appropriate pH and temperature. For our formaldehyde-free cationic fixing agents, a pH range of 5-7 is generally recommended to ensure optimal interaction and complex formation. Temperatures between 40°C and 60°C are usually sufficient for effective fixation. It is also important to note that these cationic agents should not be used in the same bath as anionic products, as this can lead to precipitation and reduced efficacy. Careful bath preparation and sequencing of treatments are vital for maximizing the performance of the fixing agent.

NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of testing and process optimization. While general guidelines are provided, specific fabric types, dye lots, and processing equipment may require adjustments to dosage, temperature, or time.
