A textile softening detergent composition contains from 5 to 70 wgt % surfactant, from 0.5 to 50 wgt % builder, from 1 to 20 wgt % crystalline laminated silicic acid and/or a corresponding alkali metal silicate and standard detergent aids. It is characterized in that the crystalline laminated silicic acid or its alkali metal salt of the general formula M.sub.2 Si.sub.x O.sub.2x+1 .multidot.y H.sub.2 O in which x stands for a number larger than 7.0, M stands for sodium, potassium or hydrogen, and y stands for a number of from 0 to 25, shows one or more reflexes unassignable to quartz, tridymite and cristobalite in the X-ray diffraction diagram in the range of the d-values of 3.0-4.0.multidot.10.sup.-8 cm. Process for rinsing textiles using the crystalline laminated silic acid or its alkali metal salts as a textile softening agent.
A textile softening detergent composition containing from 5 to 70 wgt % of at least one surfactant, from 0.5 to 50 wgt % of at least one builder, from 1 to 20 wgt % of at least one crystalline laminated silicic acid or its alkali metal salt, and standard detergent aids, the crystalline laminated silicic acid or its alkali metal salt being of the general formula
A process for rinsing textiles using a crystalline laminated silicic acid or an alkali metal salt thereof as a textile softening agent, the laminated silicic acid or its alkali metal salt of the general formula

The present invention relates to a textile softening detergent composition.
It is known that soft and fluffy textiles frequently washed in a drum washing machine become deprived of their initially pleasant feeling. The feeling becomes harder, especially when the textiles are repeatedly dried, hanging quiescently. This is due to an agglutination of fibers, also termed water stiffness, which occurs during drying.
This effect can be acted upon with the use of conditioning agents, preferably cationic surfactants, more preferably quaternary ammonium compounds. The softening effect on the textile generally has an antistatic effect associated with it. The term "softening" as used herein always means this conditioning effect on textiles; it does not relate to the softening of water by sequestration of calcium and magnesium ions inducing the hardness of water, in complex form.
Loop pile fabrics were washed 5 times in each case with one of the two following detergent compositions (the percentages being by wgt)
