WETSOFT® NE 820
WETSOFT® NE 820 is a self-dispersible polyether-amino-functional silicone fluid.
Properties
By improving hand and hydrophilic properties, WETSOFT® NE 820 considerably improves the wear comfort of textiles and is therefore particularly suitable for use with nonwovens and terry goods.
The hydrophilic properties are the result of the special orientation of WETSOFT® NE 820 on the fiber surface. This allows unrestricted moisture transport within the fabric, together with the excellent hand that is generally associated with high-quality silicone fabric softeners.
WETSOFT® NE 820 bonds more strongly to the fiber surface than glycol- and quat-functional polysiloxanes. This leads to better exhaustibility and wash resistance.
Formulations based on WETSOFT® NE 820 have a pH-stability that extends well into the alkaline range, and offer good shear resistance.
Because of its cationic structure, WETSOFT® NE 820 has limited compatibility with anionic auxiliaries such as optical brighteners. Compatibility tests should be carried out before it is used together with other chemicals.
WETSOFT® NE 820 can be used for hydrophilic treatment of fibers and textiles in diluted form, either on its own or mixed with WETSOFT® NE 810. WETSOFT® NE 820 is an ideal active substance in hydrophilic fabric softeners for treating fibers and textiles of all kinds. Hydrophobic substrates such as polyester show a distinct improvement in wetting properties. Using a formulation based on WETSOFT® NE 820 and WETSOFT® NE 810 on hydrophilic substrates can improve their hand even further without changing the spontaneous wettability.
WETSOFT® NE 820 provides woven goods and knitwear with a natural soft, silky, and supple hand.
WETSOFT® NE 820 has only little effect on the degree of whiteness in a softener formulation. As a rule no adverse effect on the shade or color fastness properties of coloured goods is observed.
WETSOFT® NE 820 formulations are used for padding, in the exhaust process and can also be used on their own or together with organic fabric softeners, polyethylene waxes and other finishing agents. The compatibility should be tested on a case-by-case basis.
Processing:
For padding, it is recommended to use a 10 to 30 g/l (25%) WETSOFT® NE 820 formulation. For the exhaust process, 0.3 to 0.8% WETSOFT® NE 820 is used, based on the weight of the textile. WETSOFT® NE 820 can easily be diluted with warm water to produce stable formulations.
Typical formulation
50.0 parts demineralized water (40 °C)
4.0 parts i-tridecyl-O-(EtO)10-H (HLB 14)
10.0 - 25.0 parts WETSOFT® NE 820
35.9 - 20.9 parts demineralized water
0.1 parts preservative
The emulsifier is dissolved in the warm (40 °C) demineralized water, then gradually add WETSOFT® NE 820 and mix until the product is clear and homogenous. Finally the second amount of water and preservative agent are added.
Even without emulsifier clear dilutions of WETSOFT® NE 820 can be produced, but might show instability if stored at elevated temperatures.
If cold water is used a high-viscosity gel phase occasionally forms, which must be thoroughly mixed in to produce a homogeneous final product. It is alternatively possible to reduce the viscosity by adding solvents such as diethyleneglycolmonobutylether.
