- the smectite clay mineral is a bentonite.
- bentonite consists for the most part of montmorillonite.
- the aluminosilicate montmorillonite is a three-layer material, composed of two SiO 4 tetrahedral layers, between which there is an octahedral layer of predominantly aluminum ions. Isomorphous replacement of the trivalent aluminum ions by divalent ions, such as calcium or magnesium, produces a negative excess charge, which can be compensated by Mg 2+ , Ca 2+ , Na + , for example.
- the bentonite By exchanging these cations, the bentonite also acts as an ion exchanger. In addition to the different charges, cations such as Na + and Ca 2+ also significantly influence the swelling behavior of the bentonite.

- the clay mineral in particular the bentonite, is present in activated form, ie divalent or trivalent cations stored between the layers are exchanged for monovalent ions, such as sodium ions or protons.

These sub- Divide mainly by the manufacturing process. Both groups have the same basic structure of a linear or branched hydrophobic hydrocarbon chain (C x ) and a hydrophilic ethylene oxide chain (EO y ) with terminal alcohol group (s). These control both the efficiency, ie the required amount of surfactant, and the temperature sensitivity of the surfactant class. Within the hydrophilic ethylene oxide group, moreover, individual ethylene oxide units can be exchanged for propylene oxide units. The resulting changes in the hydrophobic / hydrophilic character can be used specifically in the selection of surfactants.

- the use of water glass also avoids the formation of compact flocs of charged polymers and oppositely charged clay fins, which on the one hand dissolve worse and on the other hand would therefore also deposit on the fiber to a lesser extent. This effect can be circumvented by using an aqueous binder system based on a waterglass.

This may be added in a separate aqueous solution or mixed in a common solution with surfactant and N-vinylpyrollidone copolymer with the clay mineral. The addition of carrageenan while the softness is surprisingly further improved.

- Nessler's reagent (Merck, Art. No. 9028); Boric acid solution, 2%; Caustic soda, 32%; 0.1 N hydrochloric acid; NaCl solution, 0.1%; KCl solution, 0.1%
- Detection of the ionic freedom of the wash water is carried out on NH 4 + ions with the sensitive Nessler's reagent.
- the washing rate may vary between 30 minutes and 3 days depending on the type of clay.
- the washed out NH 4 + clay is removed from the filter, dried at 110 0 C for 2 hours, ground, sieved (63 micron sieve) and dried again at 110 0 C for 2 hours. Thereafter, the NH 4 + content of the clay is determined according to Kjeldahl.
- Calculation of the CEC The CEC of the clay is the Kjeldahl NH 4 + content of the NH 4 + clay (CEC of some clay minerals, see Appendix). The data are given in meq / 100 g clay.
- the cations released by the exchange are in the wash water (filtrate).
- the proportion and the type of monovalent cations ("exchangeable cations") was determined spectroscopically in the filtrate according to DIN 38406, part 22.
- the wash water (filtrate) is concentrated for AAS determination, transferred to a 250 ml volumetric flask and filled with deionized water to the measuring mark. Suitable measuring conditions for FAAS can be found in the following tables.
- the methylene blue value is a measure of the inner surface of the clay materials.
- the test of the clay material is carried out in the same way as for the test bentonite. From the used amount of methylene blue solution, the inner surface of the clay material can be calculated.
- 381 mg methylene blue / g clay correspond to a content of 100% montmorillonite according to this method.
- the clay mineral provided (as described in Table 4) is mixed with an aqueous solution of the surfactant and the copolymer used in each case.
- the following solutions 1 and 2 were prepared:
