Hydrophilic Textile Softener by Wacker for effective textile finishing

June 22, 2016 written by

Munich-based chemical company Wacker, has launched an innovative hydrophilic fabric softener, WETSOFT® NE 750 for factory textile finishing. This does not only improve the softness of textiles, but also increases the ability of the textile to absorb water. This is particularly important for towels and knitted materials that need to remain absorbent after finishing. The silicone fluid formulation is marketed as a water-free concentrate. It just needs to be diluted with water to produce a ready-to-use emulsion. WETSOFT® NE 750 is a new premium product for high-quality textiles that imparts a pleasant and full soft feel as well as excellent absorbency.

The drop test proves that textiles that have been treated with WETSOFT® NE 750 are extremely absorbent. The emulsion penetrates to the base of the fabric, even with a long pile, which facilitates water uptake. Re-dying of the material is also not a problem.

The main constituents of WETSOFT®NE 750 are block copolymers based on aminofunctional silicones and polyglycol. The silicone fluid segments arranges themselves in free-moving loops on the outside of the fabric and reduces friction between the fibres. This provides the fabric with an excellent soft feel, which even remains after washing. The polyglycol segments, on the other hand, ensure that the silicone finish, which is normally water-repellent, remains permeable to water.

The combination of softness and water absorbency is of crucial importance for high-quality textiles. Tests show that materials treated with WETSOFT® NE 750 have a pleasant, soft and full hand feel while remaining absorbent. As a result, they quickly take up moisture from skin and hair. This is due to the fact that the emulsion penetrates to the core of the fabric, even when the fabric contains long pile fibers. From a textile manufacturer’s point of view, it is important that subsequent textile corrections, such as re-dying of the material, can easily be made after the textile has been treated with the product.

WETSOFT® NE 750 offers significant advantages for textile-auxiliary formulators too.Both cotton and blended fabrics containing polyester can be finished with the product.
