Pretreatment makes all the difference. A high-quality, finished textile product that meets all the customer’s needs can only be achieved with optimised pretreatment products and processes. Whether scouring, desizing or bleaching, it is absolutely essential to have the proper detergents, wetting and sequestering agents and suitable peroxide stabilisers.
... work by complexing with or removing disruptive alkaline earth ions and water hardeners. Sequestering agents have a diverse set of tasks. They can complex with disruptive Ca, Mg, Fe and Mn ions, among others. Furthermore, they are able to reduce water hardness, disperse dyes or soil particles, stabilise hydrogen peroxide bleaching, prevent silica deposition and improve the cleaning power of detergents.
... are essential for cleaning all types of textiles. Detergents and wetting agents can quickly wet textiles, reliably remove oily contaminants or dirt, support wool milling or emulsify natural oils, waxes or silicone oils depending on the requirements. Special products take environmental aspects into account (washing with microparticles, for example) or are suitable for medical textile use.
... perform special functions during the bleaching of cotton or viscose with hydrogen peroxide. Classic bleaching agents stabilise the peroxide bleach, meaning they control the bleaching process to minimise the damage to fibres. Bleaching agents can also be activators, enabling a high degree of whiteness to be achieved starting at a bleaching temperature of 75 °C.
... protect textiles from thermal and storage yellowing. Thermal anti-yellowing agents not only reduce the tendency for PA or PA/EL goods to yellow during the heat-setting and moulding processes, they also lower the chance of CO/EL goods yellowing during heat-setting. Storage anti-yellowing agents reduce phenolic yellowing of PA and PA/L goods as well as PES/EL products and other blends. Depending on the application, there are special products that give goods a neutral pH value or help prevent unwanted brownish yellow spots caused by certain finishing processes.
