Functional silicone fluids have a decades-long successful track record as softeners in the treatment of fibers, yarns or textile fabrics. The most important starting materials for silicone manufacture, and therefore for manufacturing textile softeners, are silicon and methanol. Methanol is first converted to methyl chloride, and then reacted with elemental silicon in the Müller-Rochow process to form a mixture of different methylchlorosilanes, which are important starting materials for silicone production. In this process, Wacker uses both petrochemical and plant-based methanol.
3 functional silicone fluids are now available from the company as “eco” products: Wetsoft eco LV 810, Wacker Finish eco WR 1100 LV and Wacker Finish eco WR 1300 LV. Instead of fossil methanol, Wacker Chemie AG, Munich/Germany, uses plant-based methanol for the manufacture of these products. The method, which is based on the biomass balance method used in production, has now been certified by TÜV Nord according to the REDcert² standard.
Wetsoft eco 810 LV, particularly suitable for treating absorbent textiles such as towels, underwear and T-shirts, is based on biomethanol, which ensures resource-efficient production. It is a self-dispersing polyether-amino-functional silicone fluid with reduced volatiles content. The fluid provides textiles with the soft hand that is typical of silicones, without affecting their absorbency.
Wacker Finish eco WR 1100 LV and Finish eco WR 1300 LV are made of polydimethylsiloxanes with amino side groups and reactive chain ends. In addition to their very good effect as softeners, they also offer a certain amount of protection against moisture and stains. Finish eco WR 1100 LV is particularly well suited for treatment of synthetic or mixed fabrics. The Finish eco WR 1300 LV version is ideal for viscose or for natural fibers such as cotton or wool.
