PERIWET EN is an Environmentally Friendly Deaerating and Wetting Agent
PERIWET EN is an excellent deaerating and wetting agent with foam-inhibiting properties. The formation of fine-pored, stable foam is prevented. PERIWET EN is low-foaming due to its well-balanced combination of surfactants and tensides. The product is well biodegradable and free from mineral oils. The deaerator is non-ionic and contains no alkylphenolethoxylates (APEO; nonylphenolethoxylates, NP, NPEO). Thus, a negative impact of the product on the environment is avoided.
Good Deaerator and Wetting Agent for Bleaching and Dyeing
PERIWET EN is used in all finishing processes, for example in bleaching and dyeing, which require good deaeration and wetting. With PERIWET EN you can achieve very short wetting times. The application of PERIWET EN allows a quick, even impregnation and wetting of the goods. This has a positive influence on the quality and levelness of dyeings. Furthermore, even tightly packed cones or flocks can be rapidly deaerated. Trapped air is quickly displaced which avoids floating of voluminous fabrics.
Effectiveness of Wetting Agents is Defined by Wetting Time
The effectiveness of surface-active agents and surfactants, such as of the wetting agent PERIWET EN, can be measured for example by determining its wetting time. This is the duration between dipping a standard fabric into the surfactant solution until it is plunging. The shorter the wetting time, the better the wetting power of a wetting agent.
Application of PERIWET EN
PERIWET EN has manifold application areas and can be applied in discontinuous exhaust processes as well as in continuous padding processes. It can be used for bleaching and dyeing of cotton or wool as well as their blends as flock, yarn or rope on all kinds of dyeing machines. It can also be added as rapid wetting agent for padding liquors. Apart from that it is used for dyeing of synthetic fibers in exhaust processes. A special application is the dyeing of stockings made of polyamide and its blends with elastane.
